Four hostile reviews ran in parallel: correctness, operations, performance, design coherence. Findings synthesized below in priority order. + +## Status: spec needs revision before implementation + +The spec is bundled into one design but contains two independent changes (stateless protocol + out-of-process janitor). Three concrete design problems are unresolved. Several existing CLAUDE.md invariants are contradicted without justification. + +## Critical blockers + +### B1. Fence rule change does not actually decouple commit from compaction on FDB + +**Status: resolved in revised spec.** + +The original framing was "fence on field X vs Y." That framing dissolved when both fences (generation + head_txid) were dropped from the release hot path entirely (pegboard exclusivity is the contract; debug-mode sentinels only). What remains is a pure key-locality problem: commit and compaction both write the same META *key*, regardless of which fields they touch. + +The revised spec resolves this by **splitting META into multiple keys**: + +``` +META — head_txid, db_size_pages, static fields (commit-owned) +META/compact — materialized_txid (compaction-owned) +QUOTA — sqlite_storage_used (FDB atomic counter) +``` + +- Commits write `META` + `atomic_add(QUOTA, +bytes)` + PIDX + DELTA. +- Compactions write `META/compact` + `atomic_add(QUOTA, -bytes)` + PIDX deletes + DELTA deletes + SHARD writes. Reads `META.head_txid` as snapshot read (no conflict range). +- FDB atomic adds compose without conflict ranges. + +Net: commit and compaction never conflict on META or QUOTA. The remaining contention surface is PIDX deletes when compaction folds a pgno that a recent commit also wrote — bounded and small. The revised spec uses a conflict-range read on PIDX during compaction (option 1 in its concurrency section), with per-pgno CAS as a fallback if it ever starves. + +Breaking changes are acceptable per the revised spec, so the META split lands cleanly without a migration path. + +### B2. Single-shot commit removes the only path for large blobs + +**The claim**: "Drop multi-chunk staging; UDB chunks values internally." + +**Why it's wrong**: Today's slow path exists specifically because there's an upper bound the fast path can't handle (`SQLITE_MAX_DELTA_BYTES` cutoff plus FDB ~10MB tx-size limit). Engine CLAUDE.md explicitly says "slow-path finalize must accept larger encoded DELTA blobs because UniversalDB chunks logical values internally" — meaning today's slow path is the safety valve. Removing it makes any commit larger than the fast-path cap return `SqliteCommitTooLarge` with no fallback. + +**Resolution options**: +- Option (a) — keep multi-chunk staging as a fallback. `pending_stages` stays. Wire protocol unchanged for the slow path. Recommended for v1. +- Option (b) — client-side commit splitting. Client breaks a too-large logical commit into multiple sequential server-side commits. Requires VFS-side coordination so the user-code-level transaction stays atomic. Bigger redesign. + +**Severity**: blocker. Functional regression for any actor with non-trivial commits. + +### B3. Recovery folded into single takeover tx may exceed FDB's 5s tx limit + +**The claim**: "Fold `build_recovery_plan` into the takeover write tx." + +**Why it's wrong**: `build_recovery_plan` does three full prefix scans (DELTA, PIDX, SHARD). For actors with millions of accumulated keys after long uptime, scan + deletes + META rewrite blows FDB's tx-age budget. Today's `open()` does the scans *outside* the small atomic write, so it doesn't hit this. The spec hand-waves "same cost, different home" — not actually the same. + +**Resolution**: chunked-recovery mode with a "recovery in progress" state in META. Takeover bumps generation atomically and starts orphan cleanup; new envoy serves traffic while a dedicated recovery task (or the janitor) finishes incrementally. The orphan set is defined by `head_txid` and `db_size_pages` frozen at the takeover moment, so correctness holds across multiple txs. + +**Severity**: blocker for actors with large key counts. + +### B4. Existing CLAUDE.md fence invariant directly contradicted + +**Status: resolved in revised spec.** + +The CLAUDE.md invariant said: "sqlite-storage compaction must re-read META inside its write transaction and fence on `generation` plus `head_txid`." This existed because compaction and commit both wrote the same META key, and without the fence, compaction could rewind the head. + +In the revised spec, compaction does not write `head_txid` at all — that field lives in the `META` key, which is commit-owned. Compaction writes `META/compact` (its own key). The head-rewind risk vanishes because there is no shared write target. The fence is therefore unnecessary in release. + +The CLAUDE.md note will need updating once the revised spec lands. Action item: when the META split is implemented, update the relevant `engine/CLAUDE.md` `## SQLite storage tests` bullet to describe the new key layout instead of the fence rule. + +### B5. v1→v2 migration path is broken + +`engine/packages/pegboard/src/actor_sqlite.rs:131-138` calls `prepare_v1_migration` → `open` → `commit_stage_begin/stage/finalize`. The spec deletes all four downstream methods. Migration path silently breaks. Spec doesn't mention v1 migration at all. + +**Resolution**: either preserve the migration code path with the multi-chunk methods, or design a single-shot migration commit. + +**Severity**: blocker. + +## Major issues — fix in spec + +### M1. The "v3.bare" deliverable is mislabeled + +There is no separately-versioned `ToRivetSqlite` schema crate. The relevant ops live in `engine/sdks/schemas/envoy-protocol/v2.bare`. The actual change is a VBARE bump on envoy-protocol. Runner-protocol does NOT change. Spec mislabels deliverable and confuses readers about which protocol crate is affected. + +### M2. VBARE migration story missing entirely + +Per `engine/CLAUDE.md` "VBARE migrations": every variant must be reconstructed field-by-field, never byte-passthrough. Spec doesn't specify v2→v3 converter for `ToRivetSqliteRequestData` / `ToEnvoySqliteResponseData`, doesn't mention `versioned.rs`. Need explicit converter implementation guidance. + +### M3. Trust-boundary regression: client claims actor_id in every request + +Today, `open()` ties `(actor_id, generation)` to a specific WS connection at start. After: any envoy could claim any `actor_id`. The actual binding probably comes from the existing actor-start handshake (the WS is already pinned to one actor), but the spec doesn't say so. Easy fix: state the invariant explicitly. Verify it's actually enforced in pegboard-envoy WS setup. + +### M4. NATS publish is not free + +`async_nats::Client::publish()` is `async fn` that awaits a bounded mpsc and allocates. Spec says "fire-and-forget after WS response" but doesn't specify mechanism. Without `tokio::spawn` or `try_send`, publish runs inline on the commit response path and can backpressure under NATS slowness. Need to specify: `tokio::spawn(nats.publish(...))` so it never blocks the commit response. + +### M5. PIDX cache cold-start does duplicated scan after takeover + +Recovery's `live_pidx` BTreeMap (built during takeover-tx) is thrown away after commit; the next `get_pages` then does its own PIDX prefix scan. Two scans where today there's one (today's `open()` preloads the cache from recovery's scan). Resolution: takeover should ship the recovery's PIDX result to the new envoy via some path (e.g., a pre-warmed META hint, or the next `get_pages` accepts a "skip cache load" flag). Or accept the cost — it's one extra prefix scan per takeover, not per request. + +### M6. Lifecycle wiring is unaddressed + +`open()`/`close()`/`force_close()` are called from `actor_lifecycle.rs:189-201,237-250` on actor lifecycle events, not WS frames. Spec says "ws_to_tunnel_task" without specifying: +- Which lifecycle call sites are deleted vs retained +- How `page_indices` is evicted on actor stop +- How dev-mode (single-process) handles the janitor (in-process tokio task variant?) + +### M7. Janitor pod death loses the trigger forever + +No durability, no acks. "Next commit republishes" is only true for actively-writing actors. An actor that hits threshold and goes idle (e.g., scheduled batch job) has no recovery path until next write. Resolution: either accept this risk (with monitoring on `head_txid - materialized_txid` lag), or add a periodic safety sweep. + +### M8. NATS partition / outage scenarios + +Spec claims "next commit republishes" makes trigger loss tolerable. But: +- Bursty actors that go idle right after threshold don't retrigger +- Cross-tenant blast radius (one noisy tenant floods queue, blocks others) +- Subject namespace `sqlite.compact` is global — should be per-tenant or have priority + +Plus: no monitoring metric exists today for "how many triggers were dropped." Need a Prometheus counter on publish failure. + +### M9. Cross-process compaction trigger latency increase + +mpsc::send: sub-µs. NATS publish + queue routing + janitor pod scheduling + janitor's META read tx: 10–50ms. For sustained writes, in-flight backlog grows. Document the SLO target. + +### M10. Monitoring gaps + +Spec requires zero metrics. Operability needs: +- Per-actor `head_txid - materialized_txid` lag histogram +- NATS publish success/drop counter +- Compaction conflict-abort rate +- Takeover recovery duration histogram +- Janitor pod queue-group consumer count +- Compaction worker concurrency + +None are in scope. Required for production rollout. + +### M11. Open questions that aren't actually open + +- "PIDX-key-count optimization": deferred work, not open. Move to non-goals. +- "NATS partition handling acceptable?": already decided "yes". Not open. +- "Periodic safety sweep": decided "not in v1". Move to non-goals. +- "Single-shot commit size limit": this is genuinely B2. Promote to blocker. +- "Janitor lag SLO": genuinely open, must answer before shipping. + +## Minor issues — revision suggestions + +- **Cross-pod duplicate compaction quota math**: the math (`existing_shard_size`, `compacted_pidx_size`, `deleted_delta_size`) is computed against stale snapshots. Pod B can double-decrement bytes Pod A already decremented. Self-healing eventually but fragile. Worth a closer read of `compaction/shard.rs:288-294`. +- **Fixed-point quota recompute** required on takeover recovery (per CLAUDE.md "META writes need fixed-point sqlite_storage_used recomputation"). Spec says "recompute" without naming the fixed-point requirement. +- **PIDX cache memory bound** unspecified. With ~10K concurrent actors, K=1000 LRU entries × ~16MB each = GB-scale RAM at adversarial actor counts. Need a concrete bound. +- **Memory pressure** on single-shot commit: 8MB blob lives in three live copies (WS frame, dirty_pages Vec, LTX encoder buffer). Acceptable but worth measuring. +- **Process-wide `OnceCell` content** after the change isn't enumerated. SqliteEngine retains `page_indices`, but NATS connection, metrics handles, op_counter all need explicit homes. +- **Inspector protocol interaction** unspecified. Inspector reads SQLite META; with no `open()`, how does inspector access work? +- **Pegboard actor exclusivity** invariant (repo CLAUDE.md) should be explicitly cited as the basis for removing in-process exclusivity check. + +## Open design problems (require real design work, not just spec edits) + +In order of risk: + +1. **Compaction fence decoupling on FDB** (B1). **Resolved.** Revised spec splits META into commit-owned `META`, compaction-owned `META/compact`, and an FDB atomic-counter `QUOTA`. Plus snapshot reads on the compaction side and conflict-range PIDX reads for fold-vs-commit pgno overlap. +2. **Large-commit story** (B2). Option (a) keep slow path as fallback (lower risk, recommended for v1). Option (b) client-side splitting (bigger redesign). Pick one. +3. **Takeover tx size for big-orphan actors** (B3). Need chunked-recovery mode with "recovery in progress" META state. + +## Recommended next steps + +1. **Split spec into two**: + - **Spec A — Stateless wire protocol**: Remove `open`/`close`, drop multi-chunk staging only after option (a) is decided, fold recovery into takeover-tx with chunked-recovery mode for large actors. No janitor split. Address B2, B3, B5, M1, M2, M3, M5, M6. + - **Spec B — Out-of-process janitor**: Move compaction to separate process via NATS. Keep wire protocol unchanged. Address B1, B4, M4, M7, M8, M9, M10. + + These changes are independent and can ship separately. Bundling forces wider blast radius on rollout. + +2. **Resolve the three open design problems** (B1, B2, B3) with concrete sketches before either spec is final. + +3. **Address contradicted CLAUDE.md invariants** explicitly — either justify the change with a written rationale, or update the invariant. + +## Issues considered noise / overblown + +- Some compaction-vs-commit data-loss scenarios in correctness review depend on edge cases the existing "compare against all global PIDX refs" rule already protects against. +- Dev-mode in-process variant: easy to handle as a tokio task variant of janitor binary, not a real blocker. +- Three-copy memory pressure on 8MB single-shot commits: fine in practice. +- Cold-start race for new janitor pods joining NATS queue group: real but standard NATS behavior, not specific to this design. + +## Files referenced during review + +- `/home/nathan/r2/engine/packages/sqlite-storage/src/{engine,open,commit,read,page_index,udb}.rs` +- `/home/nathan/r2/engine/packages/sqlite-storage/src/compaction/{mod,shard,worker}.rs` +- `/home/nathan/r2/engine/packages/pegboard-envoy/src/{actor_lifecycle,sqlite_runtime,ws_to_tunnel_task}.rs` +- `/home/nathan/r2/engine/packages/pegboard/src/actor_sqlite.rs` +- `/home/nathan/r2/engine/sdks/schemas/envoy-protocol/v2.bare` +- `/home/nathan/r2/engine/packages/universaldb/src/tx_ops.rs` +- `/home/nathan/r2/CLAUDE.md`, `/home/nathan/r2/engine/CLAUDE.md` diff --git a/.agent/specs/sqlite-storage-stateless.md b/.agent/specs/sqlite-storage-stateless.md new file mode 100644 index 0000000000..cd1497025d --- /dev/null +++ b/.agent/specs/sqlite-storage-stateless.md @@ -0,0 +1,798 @@ +# Stateless SQLite Storage + Out-of-Process Compactor + +## Goals + +1. **Actor-side (pegboard-envoy) must be stateless.** No `open` / `close` ops. Every request self-describes its fence and runs against the current KV state. An actor must be safely takeoverable at any time without coordination with the previous host. In-memory state on pegboard-envoy is allowed only as a perf cache — never as the source of truth, never as a correctness fence, never as something that must survive across requests. +2. **Compactor (compaction + background work) lives in a separate process and is allowed to be stateful.** Compactor pods can hold per-actor in-memory state (in-flight tracking, plan caches, lease tables, etc.) if it helps. The actor-side is the constraint; the compactor-side is free to be stateful when it serves throughput, dedup, or latency. +3. **Must support the same SQL workload as vanilla SQLite, within UDB's transaction constraints.** Large transactions, large dirty-page sets, multi-MB blobs all need to work. The protocol cannot impose a tighter cap than UDB itself does. Where UDB has hard limits (per-tx size, per-tx age), the design must explicitly handle them — either by streaming/staging at the wire level, splitting transactions, or surfacing a clear error that the client knows how to recover from. +4. **Minimize hot-path latency.** Drop everything that isn't required for correctness on `get_pages` and `commit`. +5. **No extra reads/writes for defensive checks in release.** Trust the surrounding system contracts (pegboard exclusivity, the lost-timeout + ping protocol, UDB tx isolation) and design the hot path for perf. Defensive checks for "this should never happen" invariant violations belong behind `#[cfg(debug_assertions)]` so they fire loudly during development and CI but cost zero RTTs, zero KV ops, and zero comparisons in release builds.

If diagnostics ever need it later, add an optional return field — saves a `u64` on the wire today. + +Debug builds may carry optional `expected_generation` and `expected_head_txid` fields for invariant assertion (see "Debug-mode sentinels" below).

This system has not shipped to production.** No backwards compatibility, no migration period, no dual-running protocols. Wire shape, on-disk key layout, and `DBHead`/META schema are all free to change. The new protocol is a clean replacement. + +### What's removed from `SqliteEngine` + +The legacy `SqliteEngine` struct goes away entirely. The replacement is `ActorDb`, instantiated per-actor by the WS conn (see "What's kept" below). + +- `open_dbs` — generation cache deleted. No fence to fast-fail on in release. Debug-mode sentinel reads `META.generation` in-tx (free, piggybacks on the existing META read). +- `pending_stages` — multi-chunk staging is gone. Replaced by single-shot commit. +- `compaction_tx` — replaced by `compactor::publish_compact_trigger` (UPS publish). +- `page_indices` (process-wide HashMap) — moved into `ActorDb` (per-actor instance, cached in the WS conn's `HashMap>`). +- `open()`, `close()`, `force_close()`, `ensure_open()` — methods deleted. +- `commit_stage_begin`, `commit_stage`, `commit_finalize` — collapsed into `commit`. + +### What's kept + +- `DeltaPageIndex` (PIDX cache) — perf cache only, no protocol meaning. The cache lives **inside `ActorDb`**, scoped to that actor's lifetime on the conn (one cache per actor, dropped when the actor's `ActorDb` is removed from the conn's HashMap or when the conn drops). + +The crate exports a single per-actor type, `ActorDb`. There is no `Pump` struct, no process-wide registry, no per-conn wrapper inside sqlite-storage. The WS conn (in pegboard-envoy) owns the `HashMap>` directly: + +```rust +// Exported from sqlite_storage::pump +pub struct ActorDb { + udb: Arc, + actor_id: String, + cache: parking_lot::Mutex, + /// Cached `/META/quota`. Loaded once on the first UDB tx (whichever of + /// `get_pages` or `commit` arrives first), mutated in-process on every + /// commit.

The check happens against the in-memory cache before any UDB writes. + +Cold-cache cost: the first `get_pages` for a given actor on a given WS conn does a PIDX prefix scan inside its UDB tx. Subsequent calls on the same `ActorDb` hit RAM. Tracked via `sqlite_pump_pidx_cold_scan_total` metric. + +### Why no active-actor tracking on the WS conn + +An envoy can reconnect to a different pegboard-envoy worker node mid-flight while an actor is still active on the envoy host. When that happens, the new worker node never receives the original `CommandStartActor` for any actors that started before the reconnect — pegboard sends `start_actor` once when scheduling, not on every reconnect. So a per-conn `active_actors` HashMap (or any presence-tracking structure) would be empty/incomplete relative to what's actually running. + +Treat the WS conn as **stateless w.r.t. actor identity**. There is no authoritative per-conn list of which actors are active and no `start_actor` handler. The only per-conn state is the perf cache `HashMap>`, populated lazily as `get_pages` / `commit` requests arrive. `command_stop_actor` is the only lifecycle command kept; its sole responsibility is to remove the entry from that HashMap (and thereby drop the cache). Stale entries that survive because `stop_actor` never arrived (envoy reconnected to a different worker before pegboard noticed) are bounded by WS-conn lifetime — they evict on conn drop. + +### Quota enforcement + +`ActorDb` carries an in-memory cache of `/META/quota` (the `storage_used: Mutex>` field). The cache loads from UDB on the first request that opens a UDB tx — whichever of `get_pages` or `commit` arrives first. On all subsequent commits, the cap check is a local comparison against the cached value with no extra UDB read on the steady-state path. + +Commit flow: + +1. Take the cached `storage_used` value (loaded lazily on the first tx). +2. Compute `would_be = cached + delta_bytes` where `delta_bytes` is the sum of bytes added across META/PIDX/DELTA writes for this commit, computed before any UDB mutation. +3. If `would_be > SQLITE_MAX_STORAGE_BYTES` → reject with `SqliteStorageQuotaExceeded { remaining_bytes, payload_size }` (same shape as actor KV's `errors::Actor::KvStorageQuotaExceeded` in `engine/packages/pegboard/src/actor_kv/`). +4. Otherwise: proceed with commit, `atomic_add(/META/quota, +delta_bytes)`, and update the cache locally. + +The cap is a Rust constant in `pump::quota`: + +```rust +pub const SQLITE_MAX_STORAGE_BYTES: i64 = 10 * 1024 * 1024 * 1024; // 10 GiB +``` + +**Why the cache is safe.** The only writers to `/META/quota` are (a) commits on this exact `ActorDb` under pegboard exclusivity, and (b) the compactor (only ever decreases). The cached value is therefore always `>= true value`. Worst case: over-rejection (conservative — never lets a user write past the limit). The cache refreshes naturally on the next conn (a new `ActorDb` re-loads it). + +**Hot-path overhead.** Zero new RTTs on steady-state commits. The first commit on a new `ActorDb` reads `/META/quota` alongside `/META/head` (parallelized via `tokio::try_join!`). One extra in-memory comparison per commit. The metering pipeline is not contacted on commit at all. + +### META key split + +`META` is split into four sub-keys, each with a single writer (or atomic semantics). All live under the existing per-actor prefix `[0x02][actor_id]`. (Free to do this — the system isn't shipped, so the on-disk key layout has zero compatibility constraints.) + +``` +/META/head — head_txid, db_size_pages (commit-owned, vbare blob) +/META/compact — materialized_txid (compaction-owned, vbare blob) +/META/quota — sqlite_storage_used (atomic counter, raw i64 LE) +/META/compactor_lease — { holder_id, expires_at_ms } (compaction lease, vbare blob) +``` + +Previously-stored fields are now Rust constants. `page_size` and `shard_size` live as `PAGE_SIZE` / `SHARD_SIZE` in `pump::keys`. The per-actor cap lives as `SQLITE_MAX_STORAGE_BYTES` in `pump::quota`. There is no `/META/static` key. There is no on-disk `schema_version`, `creation_ts_ms`, or origin tag — there is one schema, and any future bump detects version by presence/absence of new fields. + +Optional: `generation` field on `/META/head` if kept for debug-mode sentinels. Not load-bearing in release. + +`/META/quota` is **value-only fixed-width little-endian signed `i64`**, not a vbare blob — FDB atomic-add expects a fixed-width LE integer. Commits do `atomic_add(/META/quota, +bytes_written as i64)`; compaction does `atomic_add(/META/quota, (-bytes_freed as i64).to_le_bytes())`. Atomic adds compose without taking conflict ranges, so commit and compaction never conflict on quota. + +**Atomic counter encoding.** The value at `/META/quota` is exactly 8 bytes. Increments encode `bytes_written` as `i64::to_le_bytes()`. Decrements encode the negative as `(-(bytes_freed as i64)).to_le_bytes()` so FDB's atomic-add sums them into a signed running total. Reads of `/META/quota` interpret the bytes as `i64::from_le_bytes`; the value should always be non-negative under correct operation. The field is signed so an out-of-order arithmetic could not corrupt the encoding, but FDB atomic-add is exact integer addition and the counter is correct as long as every code path that mutates billable bytes emits the matching atomic-add delta. There is no drift in steady state — a non-zero error means there is a bug in a quota-mutating code path, not entropy. Bugs get fixed at the call site, not by periodic recompute. + +Other breaking changes: + +- **Drop `next_txid`.** Single-shot commits derive `T = head_txid + 1` in-tx. The reservation counter only existed to support multi-chunk staging (allocate-then-stream-then-finalize). With single-shot, allocation and commit happen atomically in the same UDB tx — there is no allocated-but-not-yet-committed window. + +### Hot-path key reads + +| Op | Reads | Writes | +|---|---|---| +| `get_pages` | `/META/head` (db_size_pages) + PIDX scan + DELTA/SHARD blobs | none | +| `commit` (steady state) | `/META/head` + (PIDX upserts for dirty pgnos) | `/META/head` + DELTA chunks + PIDX upserts + `atomic_add(/META/quota, +bytes)` | +| `commit` (first on a new ActorDb, cold quota cache) | `/META/head` + `/META/quota` (in parallel via `try_join!`) + (PIDX upserts for dirty pgnos) | `/META/head` + DELTA chunks + PIDX upserts + `atomic_add(/META/quota, +bytes)` | +| compaction | `/META/compactor_lease` + `/META/head` + `/META/compact` + PIDX (snapshot) + DELTA blobs to fold + SHARD blobs being merged into | `/META/compactor_lease` (take) + `/META/compact` + SHARD writes + PIDX `COMPARE_AND_CLEAR` + DELTA deletes + `atomic_add(/META/quota, -bytes)` | +| takeover (release) | none | none | +| takeover (debug, `cfg(debug_assertions)`) | DELTA/PIDX/SHARD prefix scans for orphan classification (assert-only) | none | +| first commit (lazy META init) | `/META/head` (absent) | `/META/head` + DELTA chunks + PIDX upserts + initial `/META/quota` | + +Steady-state hot-path reads cost a single key fetch (`/META/head`) within one tx — no `try_join!` is needed because there is only one key. The first commit on a new `ActorDb` reads two keys (`/META/head` + `/META/quota` for the in-memory quota cache load); those two gets must be issued concurrently via `tokio::try_join!(tx.get(/META/head), tx.get(/META/quota))`. UDB's `tx.get()` does NOT pipeline by itself; on FDB native, `try_join!` gets real parallelism, and on RocksDB it saves the await-between-sends gap. Without `try_join!` on that first-commit path, the two gets are serialized and add a real RTT. + +Hot-path writes are unchanged in count: commit writes `head` (plus `quota` via atomic add, which doesn't take a conflict range). + +### Debug-mode sentinels + +Under `#[cfg(debug_assertions)]`, the engine asserts pegboard's exclusivity contract on every op: + +```rust +#[cfg(debug_assertions)] +{ + if let Some(expected) = request.expected_generation { + if head.generation != expected { + tracing::error!( + actor_id = %actor_id, expected, actual = head.generation, + "sqlite generation fence mismatch — pegboard exclusivity violated" + ); + return Err(SqliteStorageError::FenceMismatch { ... }.into()); + } + } + if let Some(expected) = request.expected_head_txid { + if head.head_txid != expected { + tracing::error!( + actor_id = %actor_id, expected, actual = head.head_txid, + "sqlite head_txid OCC mismatch — concurrent writer detected" + ); + return Err(SqliteStorageError::FenceMismatch { ... }.into()); + } + } +} +``` + +Release builds skip the comparison block entirely. The `expected_*` fields are parsed (small wire cost) but unused. No extra KV ops, no extra RTTs, no comparisons. + +If pegboard exclusivity is ever violated in production, the result is undefined — the engine will not catch it. Acceptable per goal 5: defensive checks must not slow the hot path. + +### Takeover + +**There is no takeover work in release.** Pegboard's reassignment transaction does not touch sqlite-storage at all in release builds. The combination of (a) v2's atomic single-shot commits, (b) UDB tx isolation, and (c) pegboard exclusivity makes orphans impossible to produce in steady state — there is no half-state to reconcile. Whatever the previous host left in UDB is, by construction, a coherent v2 actor state. + +The new envoy gets no setup signal at all. Pegboard reassigns the actor; the envoy starts receiving SQLite requests for it; on the first request, the WS conn lazily inserts an `ActorDb` into `actor_dbs`; on the first commit, that `ActorDb` seeds `/META/head` if missing as part of the commit's own UDB tx. + +**Lazy first-commit META init.** The commit path must check whether `/META/head` exists at the start of its tx. If absent, this is the first commit on this actor — seed `/META/head` with `head_txid=0`, `db_size_pages=1`, and skip the atomic-add on `/META/quota` (initial state is zero, so leave the key absent — atomic-add will set it on first non-zero delta). One extra `tx.get(/META/head)` on the first commit; runs once per actor lifetime. + +**Debug-only invariant check.** Under `#[cfg(debug_assertions)]`, `ActorDb::new` may run `takeover::reconcile(udb, actor_id)` to scan PIDX / DELTA / SHARD prefixes and assert no orphans exist. If the scan finds anything → loud structured error log identifying the violated invariant + panic in tests. This is a development-time invariant verification, not a production cleanup pass. Release builds skip this entirely; `ActorDb::new` does no UDB work. + +The `takeover.rs` module exposes a single function: `pub async fn reconcile(udb: &Database, actor_id: &str) -> Result<()>`, gated `#[cfg(debug_assertions)]`. There is no `takeover::create_actor` because creation is folded into the lazy first-commit init. + +The legacy STAGE/ key prefix from the multi-chunk staging protocol does not exist in the new design. Nothing in release cleans STAGE keys. Since SQLite v2 has not shipped, no actor in production has v2-format data; sqlite-storage exposes no migration helper. The actor v2 workflow's existing migration code (which writes SQLite state during actor v1 → actor v2) will need its destination schema updated to match this spec's v2 layout — that update is the workflow's concern, not sqlite-storage's. + +### Compactor service + +- Lives in `sqlite-storage::compactor`. Exposes `pub async fn start(config: rivet_config::Config, pools: rivet_pools::Pools) -> Result<()>`, registered as `ServiceKind::Standalone` with `restart=true` in `engine/packages/engine/src/run_config.rs`. Same pattern as `pegboard_outbound` (see `engine/packages/pegboard-outbound/src/lib.rs:85-156`). +- Uses **UPS** (`engine/packages/universalpubsub/`), not NATS directly. UPS already supports queue-group semantics (`queue_subscribe`) on all drivers (memory, NATS, postgres). No UPS changes needed. +- Internal shape: construct `StandaloneCtx::new(...)`, get UPS via `ctx.ups()?`, get UDB via `ctx.udb()?`. Same plumbing as `pegboard_outbound`. +- Subscribes to `SqliteCompactSubject` with queue group `"compactor"` (typed subject struct in `compactor::subjects`). +- Select loop with `TermSignal::get()` for graceful shutdown. On shutdown, **release any held leases before exiting** (not optional — held leases stall the next compaction by up to TTL). +- On `NextOutput::Unsubscribed`: bail out and let the supervisor restart the service. Same behavior as `pegboard_outbound`. +- Stateless: each UPS message is independent. On receiving a trigger, the per-trigger handler runs in a `tokio::spawn`d task. The handler takes the actor's `/META/compactor_lease` (skipping if another pod holds it), reads META, decides if compaction is needed (`head_txid - materialized_txid` ≥ threshold), runs `compact_default_batch`, releases the lease, exits. Aborts on fatal error. +- HPA-scaled. Adding/removing pods is just engine binary instances churning their UPS connections. +- No leader election, no distributed coordination, no sweeper task in v1. The UDB-backed lease replaces all of these for cross-pod coordination. + +**Test entrypoint convention.** `compactor::start` factors as a public `pub async fn start(config, pools) -> Result<()>` outer plus a `pub(crate) async fn run(udb, ups, term_signal) -> Result<()>` inner. Tests inject the UPS memory driver and an explicit UDB handle directly via the inner entrypoint, bypassing the engine's `Pools` plumbing. + +**`CompactorConfig`.** Exposed from `sqlite_storage::compactor`: + +```rust +pub struct CompactorConfig { + pub lease_ttl_ms: u64, // default 30_000 — must exceed FDB tx age (5s) + pub lease_renew_interval_ms: u64, // default 10_000 — TTL/3 + pub lease_margin_ms: u64, // default 5_000 — TTL/6, must exceed FDB tx age + pub compaction_delta_threshold: u32, // default 32 — head_txid - materialized_txid threshold + pub batch_size_deltas: u32, // default 32 — max deltas folded per pass + pub max_concurrent_workers: u32, // default 64 — per-pod tokio::spawn cap on triggers + pub ups_subject: String, // default "sqlite.compact" + #[cfg(debug_assertions)] + pub quota_validate_every: u32, // debug only; default 16 — manually re-tally /META/quota every Nth pass +} + +impl Default for CompactorConfig { /* ... */ } +``` + +The struct is registered inline in `engine/packages/engine/src/run_config.rs`, e.g.: + +```rust +Service::new( + "sqlite_compactor", + ServiceKind::Standalone, + |config, pools| Box::pin(sqlite_storage::compactor::start(config, pools, CompactorConfig::default())), + true, +) +``` + +**Idle-actor stuck behavior is acceptable.** An actor that crosses the compaction threshold then goes idle and loses its trigger to a UPS hiccup will not compact until it next writes. This is acceptable because storage isn't actively growing while the actor is idle, and there is no urgency. A periodic safety sweep (e.g. a CronJob iterating actors that haven't been compacted recently) is deferred to future work. + +### Metering rollup + +After every successful compaction pass, the compactor rolls up per-actor storage metrics into the namespace-level metering pipeline using the same `MetricKey` structure actor KV uses (`engine/packages/pegboard/src/namespace/keys/metric.rs`). Three new variants: + +- `SqliteStorageUsed { actor_name }` — current bytes in `/META/quota`; emitted every pass (point-in-time gauge). +- `SqliteCommitBytes { actor_name }` — bytes written across commits since the last rollup. +- `SqliteReadBytes { actor_name }` — bytes read across `get_pages` calls since the last rollup. + +For commit/read byte counters, `ActorDb` maintains in-memory per-actor counters (`commit_bytes_since_rollup` / `read_bytes_since_rollup` — see "What's kept" above). The hot path increments these counters locally on each commit and `get_pages`; no UDB writes happen for metering on the hot path. The compactor reads + zeros these counters on each pass and emits via `atomic_add` against the `MetricKey`. The counters use `parking_lot::Mutex` for the same forced-sync-context reasons as the quota cache. + +Round commit/read byte deltas to 10 KB chunks before emitting (matching actor KV's `KV_BILLABLE_CHUNK` convention — see `engine/packages/pegboard/src/actor_kv/mod.rs:164-166, 327-329`). + +The compactor is already reading `/META/quota` for the pass, so emitting `SqliteStorageUsed` costs nothing extra. The commit/read byte counters live in envoy memory, not UDB — the compactor and envoy run in different processes, so the counter values must travel via the same channel as the compaction trigger. The UPS trigger payload carries `commit_bytes_since_rollup` / `read_bytes_since_rollup` snapshots that the envoy zeroes locally as it builds the message; the compactor reads those values out of the trigger and emits the metering atomic-adds. + +**Idle-actor caveat.** Actors that never compact never emit metering. For low-activity actors this means stale billing snapshots until they next compact. Acceptable because: (a) low-activity actors have low storage churn so usage is roughly stable, (b) if billing freshness is needed for idle actors later, the existing `pegboard_actor_metrics` workflow can read `/META/quota` for SQLite actors as a one-line addition. + +**Hot-path overhead.** Zero. `ActorDb` increments local counters on commit/read; the compactor pulls them out periodically. No metering UDB writes on the hot path. + +### Compaction trigger + +After every successful commit-that-crosses-threshold, pegboard-envoy calls `sqlite_storage::compactor::publish_compact_trigger(ups, actor_id)`. The helper internally `tokio::spawn`s a UPS publish — strictly fire-and-forget, must not be awaited before sending the WS commit response. The trigger is a hint; loss is tolerable because the next commit republishes (subject to the throttle described below). + +UPS subject naming follows the existing convention (`pegboard::pubsub_subjects::ServerlessOutboundSubject` style): a typed struct implementing `Display`, owned by the storage crate. + +**Per-actor throttle.** A naive "publish on every commit at-or-above threshold" floods the compactor: a hot actor doing 100 commits/sec at threshold = 100 redundant publishes/sec, each costing UPS publish + UPS deliver + a `/META/compactor_lease` read on the receiver. To bound this, `ActorDb` throttles publishes per actor: + +- `last_trigger_at: parking_lot::Mutex>` — local-only, no UDB. +- On commit-crosses-threshold, check `now - last_trigger_at`. If `< trigger_throttle_ms` (default 500ms), skip the publish. Otherwise publish and update `last_trigger_at`. +- **First commit fires immediately.** Subsequent commits within the window are dropped. (This is throttle, not debounce — debounce would defer indefinitely under sustained load and starve hot actors of compaction.) + +**Trigger-loss safety net.** If the throttle suppresses publishes for an extended window (e.g. all triggers landed in a UPS partition or got dropped on the receiver), an actor at-or-above threshold could go indefinitely without a trigger. Cap the throttle: if `now - last_trigger_at > trigger_max_silence_ms` (default 30s) AND the actor is still at-or-above threshold, force a publish regardless of recent activity. In practice this rarely fires — UPS isn't that flaky and compaction passes finish in seconds — but it closes the loop on trigger-loss recovery for actively-committing actors. + +The throttle constants are constants in `pump::quota` (or `pump::trigger`) module, not on `CompactorConfig` — they're envoy-side, not compactor-side. + +### Debug-only quota validation + +Under `#[cfg(debug_assertions)]`, the compactor periodically verifies that `/META/quota`'s atomic-add running total matches a manually-tallied byte count from a full PIDX/DELTA/SHARD scan. Runs every Nth compaction pass per actor (default `quota_validate_every = 16`, exposed on `CompactorConfig`). + +Procedure: + +1. After the compaction pass completes, in a separate read-only UDB tx: scan PIDX + DELTA + SHARD prefixes, total billable bytes manually. +2. Read `/META/quota`. +3. Assert `manual_total == counter`. On mismatch → structured error log identifying actor + delta, panic in tests. + +This is a development-time invariant verification of atomic-add correctness. It does NOT correct the counter. Drift (if observed) means a quota-mutating call site has a bug; the fix is at the bug site, not by recompute. + +**Strictly debug-only.** Release builds skip this entirely — no extra scan, no extra read, zero overhead. Goal 5 applies. + +## Concurrency model + +The design uses two mechanisms total: pegboard exclusivity for envoy writers, and a UDB-backed lease for compaction. Plus one atomic op (`COMPARE_AND_CLEAR`) for the residual commit-vs-compaction PIDX race. + +### Envoy writers: pegboard exclusivity + +Per `engine/CLAUDE.md`: at most one envoy hosts an actor at a time. Pegboard's lost-timeout + ping protocol is the source of truth. Storage layer trusts this contract and does **not** add separate KV concurrency fences. Per goal 5, defensive in-tx checks for "two writers detected" are debug-only. + +### Compaction lease + +A compactor pod takes a UDB-backed lease before running compaction for an actor: + +``` +/META/compactor_lease → { holder_id: NodeId, expires_at_ms: i64 } +``` + +Lease take procedure: + +``` +1. Regular read (NOT snapshot read) of `/META/compactor_lease`. + The regular read takes a conflict range — two pods racing the take get + FDB OCC abort on the loser. A snapshot read here would let both pods + "take" the lease. +2. If exists, holder != me, expires_at_ms > now: skip; another pod is working. +3. Else: write `/META/compactor_lease = { my_id, now + TTL }`. +4. Run compaction work under a CancellationToken (see Lease lifecycle). +5. On graceful exit, clear the lease so the next trigger doesn't wait for TTL. +``` + +**TTL > FDB tx age (5s).** Default 30s. + +If a pod dies mid-compaction, the actor's compaction stalls for at most TTL before another pod takes over. Acceptable because compaction is throughput-bound, not latency-bound. + +The lease eliminates concurrent compactions entirely. Compaction can use snapshot reads on SHARD blobs and plain `set()` for `/META/compact` — no atomic MAX, no quota reconciliation, no SHARD-content races to defend against. + +### Lease lifecycle + +The lease is held via a local timer, a cooperative cancellation token, and a periodic renewal task. **No /META/compactor_lease reads happen inside compaction work transactions.** Renewal is the only place /META/compactor_lease is read during a compaction pass. + +Constants: + +- `lease_ttl_ms = 30_000` (TTL = 30s) +- `lease_renew_interval_ms = 10_000` (renew every TTL/3 ≈ 10s) +- `lease_margin_ms = 5_000` (margin = TTL/6 ≈ 5s, chosen > FDB tx age (5s)) + +On lease take, the compactor computes `deadline = lease_acquired_at + TTL - margin` and arms a local `tokio::time::sleep_until(deadline)`. The compaction pass runs under a `CancellationToken`. The token is tripped by either: + +- the local deadline timer firing (sleep_until completes), OR +- the renewal task observing a renewal failure. + +Renewal task (runs every `lease_renew_interval_ms`): + +1. Open a small UDB tx. +2. Regular-read /META/compactor_lease. +3. Assert `holder == me && expires_at_ms > now`. If either fails, the lease has been stolen or expired. +4. Write `expires_at_ms = now + TTL`. Commit. +5. On success: extend the local deadline. Replace the existing `sleep_until` with a fresh `sleep_until` at the new deadline. +6. On failure (lease stolen, UDB error, RPC timeout shorter than `deadline - now`): trip the cancellation token immediately. + +Compaction work checks the cancellation token before each FDB tx. Token tripped → abort, do not start new work. + +In-flight FDB transactions when the token trips are not aborted explicitly. They either commit successfully (within tx age, lease still valid) or abort on tx-age. Both outcomes are safe because the lease still grants exclusivity at commit time on the success path, and an aborted tx writes nothing on the failure path. + +This design avoids per-tx lease re-validation reads inside compaction work. It also sidesteps the "lease expired but my tx commits anyway" pathology: any tx that completes within tx-age must have started while the lease was valid, and the renewal margin keeps the deadline ahead of in-flight commits. + +### META key split (commit/compaction decoupling) + +Even with the lease preventing concurrent compactions, commit and compaction still race because they run in different processes (envoy vs. compactor). Splitting META into per-owner sub-keys decouples them at the FDB conflict-range level (full key layout in the [META key split section](#meta-key-split) above): + +``` +/META/head — commit-owned +/META/compact — compaction-owned +/META/quota — atomic counter +/META/compactor_lease — compaction lease +``` + +**Commit writes:** `/META/head` + `atomic_add(/META/quota, +bytes_written)` + PIDX upserts + DELTA chunk writes. +**Compaction writes:** `/META/compact` + `atomic_add(/META/quota, -bytes_freed)` + conditional PIDX deletes (see below) + DELTA blob deletes + SHARD blob writes. + +Compaction reads `/META/head.head_txid` (upper bound for which DELTAs are eligible) using a **snapshot read** — no conflict range taken. + +`/META/quota` uses FDB atomic add. Two atomic adds compose without taking conflict ranges. Lease ensures no two compactions decrement at once, so the "double-decrement" concern doesn't apply. + +Net effect: commits and compaction never conflict on any `/META/*` sub-key. + +### PIDX deletes: COMPARE_AND_CLEAR + +Compaction must delete PIDX entries for pages it folded into a shard. If a commit writes a *newer* PIDX entry for the same pgno between compaction's plan phase and its commit, blindly deleting would erase the new commit's claim. + +Compaction uses FDB's `COMPARE_AND_CLEAR(key, expected_value)` atomic op. The op clears the key iff its current value equals `expected_value`, atomically at commit time. **It takes no read conflict range** — the value comparison happens during commit application, not via OCC. + +``` +Plan phase (snapshot reads, no conflicts): + for each delta T in compaction window: + decode T's LTX → page set + for each pgno in union of page sets: + snapshot_get(PIDX[pgno]) → owner_txid + if owner_txid in {our K folded deltas}: + add (pgno, owner_txid) to fold plan + +Write phase (no conflicts on PIDX): + set SHARD blobs + for each (pgno, expected_txid) in fold plan: + COMPARE_AND_CLEAR(PIDX[pgno], expected_txid_be_bytes) + clear_range each folded DELTA's chunks + set /META/compact, atomic_add /META/quota +``` + +Race resolution: if a commit writes `PIDX[5] = T_new` between compaction's snapshot and commit, the COMPARE_AND_CLEAR sees `T_new ≠ T_old` and no-ops. Newer commit's claim survives. The SHARD write is shadowed by the newer DELTA — harmless because PIDX shadows SHARD on read. + +UDB needs to expose `COMPARE_AND_CLEAR`. FDB has it natively (`MutationType::COMPARE_AND_CLEAR`). Small wrapper-only addition in `engine/packages/universaldb/` if not already present. + +### PIDX deletion atomicity + +When compaction folds deltas into a shard, the old DELTA blobs **and** their PIDX `COMPARE_AND_CLEAR` ops must be in the same UDB tx as the shard write. Otherwise reads pay extra "stale-PIDX → shard fallback" round-trips until the entries are cleaned. + +### Compaction concurrent with reads + +UDB tx isolation: reads see consistent snapshot. If pegboard-envoy's PIDX cache points to a delta that compaction just deleted, the existing stale-PIDX fallback (`read.rs:144-150`) handles it — reads the shard instead, evicts the stale cache row. Self-healing. + +### Shrink race during compaction + +A commit that lowers `db_size_pages` orphans pages above the new EOF. CLAUDE.md requires shrink to delete above-EOF PIDX rows AND above-EOF SHARD blobs in the same tx as the commit. + +This creates a race with compaction: if compaction reads `/META/head.db_size_pages` via snapshot at plan time, runs against the old EOF, then writes a SHARD that's now above EOF — that SHARD is leaked permanently and the quota counter drifts downward only. + +**Fix:** the compactor's WRITE tx does a REGULAR (non-snapshot) read of `/META/head.db_size_pages` at the start of the write phase. A concurrent shrink commit then conflicts on `/META/head` and the compactor's tx aborts and retries with the new EOF. Cost: one extra in-tx read; recreates a brief `/META/head` conflict only during the write-phase window, not during the snapshot-heavy plan phase. + +The other concern that comes up around shrink + compaction — "stale SHARD bytes for un-compacted-but-superseded pgnos" — is self-healing via PIDX shadowing on read and is not a bug. A SHARD blob whose bytes are obsolete is harmless as long as some PIDX row points to a newer DELTA, because reads go through PIDX first. + +## Engine infrastructure dependency + +This spec depends on a new `NodeId` type added to `rivet_pools::Pools`. The `NodeId` is generated at engine startup as `Uuid::new_v4()`, accessed via `pools.node_id() -> NodeId`. It is random, **not** derived from `HOSTNAME` or any other deployment-shaped identifier. + +The `NodeId` infrastructure is a separate engine-wide change to `engine/packages/pools/` that lands before the compactor work in this spec. + +The compactor uses `pools.node_id()` as the `/META/compactor_lease.holder_id` value. The lease's `holder_id` field is a `NodeId` (essentially a `Uuid`) — not the earlier proposed `LeaseHolder { pod_name, instance_uuid }` shape. All metrics emitted by the compactor and pump include a `node_id` label sourced from `pools.node_id()`. + +## Hot-path latency analysis + +Steady-state `get_pages` / `commit` reads only `/META/head` — a single key fetch, no `try_join!` needed. The first commit on a new `ActorDb` reads `/META/head` and `/META/quota` concurrently via `tokio::try_join!`; without it the two gets are serialized and add a real RTT. + +| Op | Before | After | Change | +|---|---|---|---| +| `open()` | 1 RTT + 3 prefix scans + atomic write | gone | removed | +| `close()` | 1 RTT, in-mem cleanup | gone | removed | +| `get_pages` (warm cache) | 1 RTT, identical UDB ops | 1 RTT (`/META/head` + PIDX cache hit + DELTA/SHARD) | 0 | +| `get_pages` (cold cache, post-takeover) | 1 RTT (PIDX preloaded by `open`) | 1 RTT (PIDX prefix scan in-tx; tracked via `sqlite_pump_pidx_cold_scan_total`) | 0 RTT but extra in-tx scan once per WS conn | +| `commit` (steady state) | 1 RTT, identical UDB ops | 1 RTT, identical UDB ops | 0 | +| `commit` (first on a new ActorDb) | n/a | 1 RTT (`/META/head` + `/META/quota` via `try_join!`) | 0 (with `try_join!`) | +| `commit` (multi-chunk) | `2 + N` RTT × tx | 1 RTT × tx | -N to -(N+1) | +| `ensure_open` per op | HashMap lookup | gone | -sub-µs | +| Compaction trigger | `mpsc::send` (free) | `ups.publish` via `tokio::spawn` (~tens of µs, off path) | +negligible | + +No UDB op gets heavier on the hot path.

No real NATS broker required. +- **Crash-recovery tests** use `checkpoint_test_db()` + `reopen_test_db()` for real persisted-restart state. +- **Latency tests** live in a dedicated integration test binary because UDB caches `UDB_SIMULATED_LATENCY_MS` once via `OnceLock`; mixing latency and non-latency tests in the same binary corrupts the cached value across tests. +- **Failure-injection tests** use `MemoryStore::snapshot()`. Note that the `fail_after_ops` budget continues consuming after the first injected error. +- **Lease-expiry tests** use `tokio::time::pause()` + `advance()` for determinism. +- **COMPARE_AND_CLEAR conflict tests** verify the no-op path on stale-PIDX (commit writes `PIDX[pgno] = T_new` before compaction's CAS lands). +- **Test entrypoint convention.** `compactor::start` factors into a public `start(config, pools)` outer and a `pub(crate) async fn run(udb, ups, term_signal)` inner. Tests inject the memory-driver UPS directly via the inner entrypoint without going through the engine's `Pools` plumbing. + +## Implementation strategy + +**Stages do not need to leave the codebase in a working/compilable state at intermediate boundaries.** The rewrite is a single LLM-assisted greenfield effort. The stage breakdown organizes the work but does not gate intermediate ships. The legacy and new crates can coexist as non-compiling intermediate state during the rewrite; only the final delivery needs to compile and pass tests. + +This is a rewrite, not an in-place edit. The scope of change (new wire shape, new key layout, new concurrency model, new compactor service) is too large for incremental modification.

Battle-tested, format unchanged. Subtle correctness properties documented in `engine/CLAUDE.md` (zeroed 6-byte sentinel, varint page index, page-frame layout). Do not rewrite. +- `page_index.rs` → `pump/page_index.rs` — `DeltaPageIndex` data structure. Cache semantics carry forward unchanged. +- `error.rs` → `pump/error.rs` — error types. Lift, then prune variants that no longer apply (e.g., `FenceMismatch` becomes debug-only, multi-chunk error variants delete entirely). +- PIDX value encoding — raw big-endian `u64`. Same in the new design. +- `test_utils/` — lift unchanged. + +**Do not lift:** + +- The legacy quota fixed-point recompute math. `/META/quota` is a fresh FDB atomic counter; the legacy recompute math is **not** needed. It existed only because quota lived in the head's serialized blob and the encoded size depended on the field itself. With `/META/quota` as a separate atomic counter that property is gone, and the math is obsolete. + +**Rewrite from scratch in `pump/`:** + +- `actor_db.rs` — `ActorDb` struct (replaces legacy `SqliteEngine`). Per-actor handle owning UDB ref clone, actor_id, and `parking_lot::Mutex` cache. Public surface: `new(udb, actor_id)`, `get_pages(pgnos)`, `commit(dirty_pages, db_size_pages, now_ms)`. No `open_dbs`, no `pending_stages`, no `compaction_tx`, no process-wide HashMap, no `Pump` struct. +- `commit.rs` — single-shot only. Delete `commit_stage_begin` / `commit_stage` / `commit_finalize`. The new `commit` is dramatically smaller. Reads `/META/head` only on the steady-state path; on the first commit for a new `ActorDb`, reads `/META/head` + `/META/quota` concurrently via `tokio::try_join!` to seed the in-memory quota cache. +- `read.rs` — simpler. No fence check, no `ensure_open` call. Reads `/META/head` only. +- `keys.rs` — new layout: `/META/{head,compact,quota,compactor_lease}` (no `/META/static`). Plus existing `/SHARD`, `/DELTA`, `/PIDX` unchanged. Owns the `PAGE_SIZE: u32 = 4096` and `SHARD_SIZE: u32 = 64` constants. +- `types.rs` — `DBHead` schema changes (drop `next_txid`, optional `generation` for debug-only). No `SqliteOrigin` enum. `SqliteMeta` shape is reduced to only the fields actually persisted on `/META/head` and `/META/compact`. +- `udb.rs` — add `COMPARE_AND_CLEAR` wrapper if `universaldb` doesn't already expose it. Otherwise lift unchanged. + +**Not in `pump/`:** + +- `open.rs` — delete entirely from new code. No `open()`, `close()`, `force_close()`, `ensure_open()`. Takeover logic moves to `takeover.rs` (Stage 4). +- `compaction/` — moves to `compactor/` (Stage 3). + +All tests rewrite (wire shape change). New tests under `tests/`, not inline. + +### Stage 3: greenfield `compactor/` module + +Inside `sqlite-storage/src/compactor/`. Pure greenfield. Depends on `pump/` for storage primitives. + +- `worker.rs` — `pub async fn start(config, pools) -> Result<()>`. Connects UPS, queue-subscribes `SqliteCompactSubject` with group `"compactor"`, runs select loop with `TermSignal`. Same shape as `engine/packages/pegboard-outbound/src/lib.rs:158-163`. +- `subjects.rs` — `SqliteCompactSubject` typed struct implementing `Display`. Convention from `pegboard::pubsub_subjects`. +- `publish.rs` — `publish_compact_trigger(ups, actor_id)`. Fire-and-forget; internally `tokio::spawn`s the publish so callers can't forget to detach. +- `lease.rs` — `/META/compactor_lease` take/check/release helpers. Pure UDB, no UPS. +- `compact.rs` — `compact_default_batch(&pump, actor_id)`. Port of `sqlite-storage-legacy/src/compaction/`, adapted for new key layout, lease-based concurrency, and `COMPARE_AND_CLEAR` for PIDX deletes. +- `shard.rs` — per-shard fold + merge logic. Lift the fold math from legacy `compaction/shard.rs`; rewrite the orchestration around it. + +Service registration: add one line to `engine/packages/engine/src/run_config.rs`: + +```rust +Service::new( + "sqlite_compactor", + ServiceKind::Standalone, + |config, pools| Box::pin(sqlite_storage::compactor::start(config, pools)), + true, +), +``` + +### Stage 4: debug-only invariant check (`takeover.rs`) + +`sqlite-storage/src/takeover.rs`. Gated entirely behind `#[cfg(debug_assertions)]`. Not compiled in release. + +- Public surface (debug only): `pub async fn reconcile(udb: &Database, actor_id: &str) -> Result<()>`. +- Behavior: scan PIDX / DELTA / SHARD prefixes; classify any rows as orphans (above EOF, above `head_txid`, dangling DELTA refs, etc.); if any are found → structured error log + panic in tests. Does NOT delete anything; this is invariant verification, not cleanup. +- Lift: orphan classification logic from `sqlite-storage-legacy/src/open.rs::build_recovery_plan` for the classification rules. Drop the mutation-builder code — debug-only just asserts. +- Wired into `ActorDb::new` under the same `#[cfg(debug_assertions)]` gate. Pegboard does not call this. Pegboard does not import `sqlite_storage::takeover` at all; it imports nothing sqlite-related on takeover. + +Release build behavior: `ActorDb::new` does no UDB work. Trust v2 invariants. If an invariant violation actually occurs in production, behavior is undefined (acceptable per goal 5). + +### Stage 5: rewire pegboard-envoy + +Mostly net deletion. + +- `engine/packages/pegboard-envoy/src/conn.rs` — **delete the `active_actors` HashMap entirely.** The conn holds no authoritative per-actor state. Add a single field `actor_dbs: scc::HashMap>` for the per-WS-conn cache. Entries are upserted lazily by the SQLite request handlers (first `get_pages` or `commit` for an actor on this conn calls `entry_async(...).or_insert_with(|| Arc::new(ActorDb::new(udb.clone(), actor_id)))`). See "Why no active-actor tracking on the WS conn" above for the reconnection rationale. +- `engine/packages/pegboard-envoy/src/actor_lifecycle.rs` — **delete `start_actor` entirely** (and the `open()` / `close()` / `force_close()` call sites at lines `189-201`, `237-250`). **Keep `stop_actor`**, but its sole responsibility shrinks to `conn.actor_dbs.remove_async(&actor_id).await` — no `close()` call, no `active_actors` mutation, no generation tracking. +- `engine/packages/pegboard-envoy/src/conn.rs` command dispatch — drop the `CommandStartActor` branch entirely (the WS conn doesn't react to start_actor; actor presence is implicit via the SQLite request stream). Keep the `CommandStopActor` branch routing to the new lightweight `stop_actor`. +- When pegboard destroys an actor (lifecycle teardown that clears `/META`, `/SHARD`, `/DELTA`, `/PIDX`), it must **also clear `/META/compactor_lease`** for that actor in the same teardown transaction. Otherwise dead lease keys accumulate in UDB indefinitely. +- `engine/packages/pegboard-envoy/src/sqlite_runtime.rs` — delete `CompactionCoordinator` spawn. Hold the conn's UDB ref and a UPS handle. +- `engine/packages/pegboard-envoy/src/ws_to_tunnel_task.rs` — delete open/close/stage handlers. SQLite request handlers (`get_pages`, `commit`) look up or lazily insert the `Arc` in `conn.actor_dbs`, then call methods directly: `actor_db.get_pages(pgnos).await?` / `actor_db.commit(...).await?`. After a commit-crosses-threshold, call `sqlite_storage::compactor::publish_compact_trigger(&ups, actor_id)`. + +### Stage 6: wire-protocol schema + +- New schema in `engine/sdks/schemas/envoy-protocol/`. The current schema is `v2.bare`; this is a VBARE bump to `v3.bare` (or whatever the next version is — confirm with `engine/CLAUDE.md` "VBARE migrations" rules). +- **Write the new protocol as a fresh schema. No reverse compatibility, no field-by-field converter** — breaking changes are unconditionally acceptable since the system has not shipped to production. +- Note: this contradicts the general `engine/CLAUDE.md` "VBARE migrations" guidance ("never byte-passthrough; always reconstruct"). That rule exists for production-shipped schemas; this one hasn't shipped, so the rule doesn't apply. +- Update `PROTOCOL_VERSION` constants in matched envoy-protocol crates. + +### Stage 7: delete legacy + +Once Stage 5 is complete and tests pass: + +``` +rm -rf engine/packages/sqlite-storage-legacy +``` + +Drop the workspace entry, update any remaining imports. + +### Stage 8: update `engine/CLAUDE.md` + +Update the SQLite-storage section in `engine/CLAUDE.md` to match the new design: + +- **Remove**: the bullet that says "compaction must re-read META inside its write transaction and fence on `generation` plus `head_txid`." That note is obsoleted by the META key split — compaction writes `/META/compact` (its own key) while commits write `/META/head`, so no shared write target exists and the fence is unnecessary. +- **Remove**: the takeover "in one atomic_write" bullet entirely. There is no takeover work in release; pegboard's reassignment transaction does not touch sqlite-storage. v2's atomic single-shot commits make orphans impossible by construction. Debug builds run an invariant scan via `takeover::reconcile` (see Stage 4) but this is verification-only, not cleanup. +- **Verify** (still applies): "shrink writes must delete above-EOF PIDX rows and SHARD blobs in same commit/takeover transaction" — this rule is preserved and enforced (see the Shrink race during compaction subsection). +- **Update**: any "process-wide `OnceCell` SqliteEngine" reference becomes "per-actor `ActorDb` instances cached on the WS conn." Any `CompactionCoordinator` reference is gone (replaced by the standalone compactor service). +- **Remove**: STAGE-related notes (multi-chunk staging is gone; the STAGE/ key prefix does not exist in the new design). +- **Keep**: PIDX value encoding (raw big-endian `u64`) — unchanged. +- **Update test conventions**: tests live in `engine/packages/sqlite-storage/tests/`, not inline. This overrides any older "keep coverage inline" bullet. + +## Open questions + +- **PIDX-key-count optimization.** Today commit reads existing PIDX entries per pgno for quota math (`commit.rs:285-303`) when cache is cold. An incremental counter in META would skip those reads. Worth doing? Direct latency win on cold-cache commits, small META change. Not required by the three goals but serves goal 3. +- **Compactor lag SLO.** Need a target for `head_txid - materialized_txid` lag and HPA tuning. What's the alert threshold? +- **UPS partition handling.** If pegboard-envoy publishes during a UPS/NATS outage, the trigger is lost. Recovery: next commit republishes. Acceptable? +- **Single-shot commit size limit.** UDB chunks values internally but there's a practical upper bound. What's the cutoff before we'd need to reintroduce streaming? Likely above any actor's typical write set, but worth verifying. + +## Future work + +Out of scope for this spec but worth scoping next: + +- **Migrate KV to SQLite.** Today actor KV (`actor_kv` ops) is a separate UDB-backed key/value store, distinct from the SQLite engine. With stateless SQLite in place and the compactor handling background work, the KV store becomes a candidate to fold into a single `_kv` table on the actor's SQLite database. Benefits: one storage backend per actor, KV transactions become real SQL transactions, KV reads benefit from the same PIDX/SHARD caching, no separate quota accounting. Open questions: backwards-compat for existing KV data, transactional semantics across what was previously two stores, whether the existing 128 KB KV value limit changes. + +## Files affected + +### Renamed +- `engine/packages/sqlite-storage/` → `engine/packages/sqlite-storage-legacy/` (Stage 1; deleted entirely in Stage 7). + +### Greenfield in `sqlite-storage/src/pump/` (Stage 2) +- `mod.rs` — exports `ActorDb` (the per-actor handle, replaces legacy `SqliteEngine`). +- `actor_db.rs` — `ActorDb` struct: per-actor UDB ref + `actor_id` + `Mutex` cache.

Each story targets one failing (or skipped-but-expected-to-run) test. After fixing, update `.agent/notes/driver-test-progress.md` to mark the corresponding entry `[x]` and append a PASS log line.\n\n===== FAILING / SKIPPED TESTS =====\n\nFast suite:\n1. actor-conn > Large Payloads > should reject request exceeding maxIncomingMessageSize (timed out 30s)\n2. actor-conn > Large Payloads > should reject response exceeding maxOutgoingMessageSize (timed out 30s)\n3. actor-inspector > POST /inspector/workflow/replay rejects workflows that are currently in flight (timed out 30s)\n4. actor-workflow > workflow steps can destroy the actor (AssertionError: actor still running)\n5. conn-error-serialization > error thrown in createConnState preserves group and code through WebSocket serialization (timed out 30s)\n\nSlow suite:\n6. actor-sleep-db > schedule.after in onSleep persists and fires on wake (AssertionError: expected startCount 2, got 3)\n7. hibernatable-websocket-protocol > SKIP under bare/static — whole suite is gated behind `driverTestConfig.features?.hibernatableWebSocketProtocol`. Needs a plan to actually run the suite.\n\n===== ARCHITECTURAL CONTEXT =====\n\n- rivetkit-core (Rust) owns all lifecycle/state/dispatch state machine.\n- rivetkit-napi (Rust) is the NAPI binding layer; no load-bearing logic.\n- rivetkit (TypeScript) is the user-facing SDK; owns workflow engine, agent-os, client library, and Zod validation.\n- CBOR at all cross-language boundaries. JSON only for HTTP inspector endpoints.\n- Errors cross boundaries as universal `RivetError` (group/code/message/metadata).\n\n===== INVARIANTS =====\n\n- Every story must root-cause the failure; no retry-loop flake masking. Tests that time out at 30s almost always indicate a bug in core/napi/typescript that never completes or never surfaces an error, not a 'slow test' that needs a longer timeout.\n- Never use `vi.mock`, `jest.mock`, or module-level mocking; tests run against real infrastructure.\n- Every `vi.waitFor` call must have a one-line comment explaining why polling is necessary.\n- Errors thrown in core/napi/typescript paths must reach the client as structured `RivetError` (group/code/message/metadata) through the relevant transport (WebSocket, HTTP, SSE).\n- If the failure reveals a missing enforcement in core, fix in core (not TS). If it reveals missing translation at the NAPI boundary, fix in NAPI. TS fixes only if the test is itself wrong OR the logic is TS-only (workflow engine, Zod validation).\n\n===== RUN COMMANDS =====\n\nFrom repo root:\n\n- Build TS: `pnpm build -F rivetkit`.\n- Build NAPI (only when Rust under rivetkit-napi or sqlite-native changes): `pnpm --filter @rivetkit/rivetkit-napi build:force`.\n- Targeted driver test (single test): `pnpm -F rivetkit test tests/driver/.test.ts -t \"\"`.\n- Whole driver test file: `pnpm -F rivetkit test tests/driver/.test.ts`.\n- Per `.claude/reference/testing.md`: prefer the single test file via its filename and the `-t` filter while iterating. Verification must run the full file without `-t`.\n\n===== ACCEPTANCE RULE FOR EVERY STORY =====\n\nEvery story MUST include, as acceptance criteria, that the ENTIRE relevant test file (not just the single `-t` filter) passes under the static/http/bare matrix. Individual-test filtered runs are fine while iterating, but verification uses the whole file so we catch regressions in sibling tests introduced by the fix.\n\n===== READ BEFORE STARTING =====\n\n- `.agent/notes/driver-test-progress.md` — the failure log this PRD works from.\n- `CLAUDE.md` at repo root — layer constraints, error handling rules, fail-by-default runtime rules.\n- `rivetkit-typescript/CLAUDE.md` — tree-shaking boundaries, raw KV limits, workflow context guards, NAPI receive loop invariants.\n- `.claude/reference/testing.md` — Vitest filter gotchas, driver-test parity workflow.", + "userStories": [ + { + "id": "DT-001", + "title": "Fix actor-conn: reject request exceeding maxIncomingMessageSize", + "description": "`tests/driver/actor-conn.test.ts:652` (`should reject request exceeding maxIncomingMessageSize`) times out at 30s.

Scope is the `rivetkit-typescript/` workspace, with PRIMARY focus on `packages/rivetkit/package.json`. Secondary focus: every other published package in `rivetkit-typescript/packages/*/package.json` (not the fixture/example packages and not `rivetkit-napi` native build deps).\n\nGoal: the `dependencies` field of each PUBLISHED package should list ONLY what its runtime source code actually imports under `src/` at runtime. Everything else gets deleted outright, moved to `devDependencies`, or moved to `peerDependencies` (with an explicit reason).\n\nCURRENT DEPENDENCIES of `packages/rivetkit` to audit (direct runtime deps list):\n\n- `@hono/node-server`, `@hono/node-ws`, `@hono/zod-openapi`\n- `@rivet-dev/agent-os-core`\n- `@rivetkit/bare-ts`, `@rivetkit/engine-cli`, `@rivetkit/engine-envoy-protocol`\n- `@rivetkit/rivetkit-napi`, `@rivetkit/traces`, `@rivetkit/virtual-websocket`, `@rivetkit/workflow-engine`\n- `cbor-x`, `get-port`, `hono`, `invariant`, `p-retry`, `pino`, `uuid`, `vbare`, `zod`\n- peerDependencies: `drizzle-kit`, `eventsource`, `ws`\n\nMETHOD (do this for every published package in `rivetkit-typescript/packages/*`):\n\n1. For each declared dependency `X`, run a search for any runtime import — `import ... from \"X\"` or `require(\"X\")` or `import(\"X\")` — across `src/` of that package. Ignore matches in `tests/`, `fixtures/`, `scripts/`, `docs/`, `*.test.ts`, `*.spec.ts`, `vitest.config.*`, `tsup.config.*`, and build config files. Skip type-only imports from `@types/*` — those should be devDependencies.\n2. Categorize each dep into one of:\n - `RUNTIME` — imported by code under `src/` that ships in the built output. Keep in `dependencies`.\n - `DEV-ONLY` — only used by tests, fixtures, build tooling, scripts, or codegen. MOVE to `devDependencies`.\n - `PEER` — consumers are expected to install this themselves (optional adapters like drizzle/eventsource/ws). Keep or promote to `peerDependencies` (mark optional if appropriate).\n - `UNUSED` — no runtime AND no dev-tool caller anywhere in the package. DELETE.\n3. For tree-shakeable optional subpaths (e.g. things gated behind a specific import entrypoint such as `rivetkit/workflow` or `rivetkit/db`), confirm the import graph is tree-shake-clean: importing the main entrypoint must not pull the optional dep. If it does, fix imports before demoting.\n4. Respect `rivetkit-typescript/CLAUDE.md`'s tree-shaking boundaries:\n - `@rivetkit/workflow-engine` must not be imported outside the `rivetkit/workflow` entrypoint.\n - SQLite runtime must stay on `@rivetkit/rivetkit-napi`; do NOT reintroduce WASM SQLite.\n - `rivetkit/db` is the opt-in for SQLite.\n - Core drivers remain SQLite-agnostic.\n5. For each dep you move or delete, write a one-line justification in the story's final progress note in `.agent/notes/dep-audit-rivetkit-typescript.md` (new file). Format: `| package | dep | decision | reason |` table.\n\nCONSTRAINTS:\n\n- Do NOT break any driver tests. Run the static/http/bare fast + slow driver suites end-to-end before marking this story `passes: true`.\n- Do NOT rewrite functionality just to shed a dep. If a dep is load-bearing, leave it alone and note it.\n- Do NOT touch native build-time deps in `packages/rivetkit-napi/package.json` (napi-rs, Cargo deps via `build:force`).\n- Peer-dep changes are user-visible. Each peer-dep addition or promotion needs a one-line CHANGELOG entry in the package.\n\nINCLUDE IN SCOPE: every published package.

READ THAT SPEC FIRST. This story supersedes the deleted `handler-serve-restoration.md` spec; the old TS-reverse-proxy approach was wrong.\n\nCORE INSIGHT: `.handler()` is not a user-traffic gateway. It is the four-route serverless runner endpoint (`GET /`, `GET /health`, `GET /metadata`, `POST /start`) that the engine calls to wake a runner inside a serverless function's request lifespan. The meaningful route is `POST /start`, which accepts a binary envoy-protocol payload, opens an SSE stream back to the engine, calls `envoy.start_serverless_actor(payload)`, and keeps the SSE alive with pings until the envoy stops or the request aborts.\n\nLAYER SPLIT (per spec section 'Architecture'):\n\n1. `rivetkit-core` (Rust) gets a new `serverless` module owning: URL routing for `/api/rivet/*` (configurable base path), `x-rivet-{endpoint,token,pool-name,namespace}` header parsing, endpoint/namespace validation (port `normalizeEndpointUrl` + `endpointsMatch` + regional-hostname logic from `feat/sqlite-vfs-v2:rivetkit-typescript/packages/rivetkit/src/serverless/router.ts` with identical behavior + unit tests), envoy startup reuse, `envoy.start_serverless_actor(payload)` invocation, SSE framing + ping keepalive loop, abort propagation. Single entrypoint: `async fn handle_request(req: ServerlessRequest) -> ServerlessResponseStream`. Rust-only; no NAPI changes yet in this step — core comes first with Rust tests.\n\n2. `rivetkit-napi` exposes exactly one new method: `CoreRegistry.handleServerlessRequest({ method, url, headers, body: Buffer }, { writeChunk, endStream }, abortSignal)`. Returns `Promise<{ status, headers }>`; body chunks flow through `writeChunk` TSF callback; stream terminates via `endStream` (with optional `{ group, code, message }` on error); abort via the passed `AbortSignal` hooked through the existing `cancellation_token.rs` TSF pattern. Thin binding; no logic.\n\n3. `rivetkit-typescript/packages/rivetkit`: `Registry.handler(req)` builds the NAPI payload, creates a `ReadableStream` whose controller is fed by `writeChunk` + closed by `endStream`, returns `new Response(stream, { status, headers })`. `Registry.serve()` returns `{ fetch: (req) => this.handler(req) }`. Drop the `removedLegacyRoutingError` throws from `src/registry/index.ts:75-95`.\n\nSTREAMING SHAPE:\n- Response body streams from Rust to JS via a `ThreadsafeFunction` (`writeChunk`). Core writes pre-framed SSE bytes (e.g. `event: ping\\ndata:\\n\\n`); TS never parses SSE.\n- Request body is a single `Buffer` (CBOR-wrap `{method, url, headers, body}` once on the TS side; pass the Buffer through to Rust without per-chunk inbound streaming — `/start` payloads are bounded and read-once).\n- `req.signal` forwarded as `abortSignal`. `ReadableStream` cancel callback calls a NAPI `cancel()` to stop the Rust SSE loop.\n\nHIGH-LEVEL `registry.start()`:\n- Three-line convenience: `await startEnvoy(); printWelcome();`. The engine subprocess already binds user-facing ports when `startEngine: true`.\n- Static-file serving: check if the engine subprocess already has a `staticDir` flag. If yes, wire `RegistryConfig.staticDir` through to the engine args. If no, document the gap in CHANGELOG and punt to a follow-up story.\n- No new HTTP listeners in rivetkit-typescript.\n\nSCOPE / EXCLUSIONS:\n- Node primary (Bun should also work since it supports NAPI + standard `fetch`/`Response`). Cloudflare Workers / Deno are OUT of scope for v1 (NAPI doesn't load on V8-only runtimes).\n- Inbound request-body streaming is out of scope (bounded `/start` payload only).\n- Response streaming is SSE only in v1 (same framing as old `streamSSE`).

Do NOT run this on the default `04-22-chore_rivetkit_core_napi_typescript_follow_up_review` branch.\n\n- Worktree: `/tmp/rivet-publish-fix` (NOT `/home/nathan/r5`)\n- Branch: `04-22-chore_fix_remaining_issues_with_rivetkit-core` (this is PR #4701)\n- State: clean, tracking origin, 5 commits ahead of `8264cd3f7`.\n- ALL edits, builds, `cargo tree` checks, commits, and pushes happen INSIDE `/tmp/rivet-publish-fix`.\n- Do NOT touch `/home/nathan/r5` for this story.\n\n===== WHY =====\n\nPublished `@rivetkit/rivetkit-napi-linux-x64-gnu@0.0.0-pr.4701.a818b77` fails to load on Debian 12 Bookworm:\n\n Error: libssl.so.1.1: cannot open shared object file\n\n`ldd` on the `.node` shows `libssl.so.1.1` / `libcrypto.so.1.1 => not found`. Build host is `rust:1.89.0-bullseye` (Debian 11, OpenSSL 1.1); consumer hosts on Bookworm+/Ubuntu 22.04+/RHEL 9+ have `libssl.so.3`. Every modern Linux consumer is broken.\n\n===== ROOT CAUSE =====\n\nThe `.node` is a pre-compiled blob. The `openssl` dep is not in any npm tree — it was baked in at Rust build time via:\n\n rivetkit-napi → rivetkit-core → rivet-pools → rivet-metrics\n → opentelemetry-otlp → opentelemetry-http\n → reqwest (default features → default-tls → native-tls on Linux → openssl-sys)\n\nEverything else in the workspace already uses rustls (tokio-tungstenite configured with rustls features; `rivetkit-rust/packages/client` explicitly passes rustls). The workspace-level `reqwest` is the leak — it does NOT set `default-features = false`, so every transitive user gets the native-tls default.\n\n===== EXISTING REQWEST USAGES (AUDIT) =====\n\n- `engine/sdks/rust/api-full/Cargo.toml:15`: `reqwest = { version = \"^0.12\", default-features = false, features = [\"json\", \"multipart\"] }` — no TLS features. If the crate makes https calls, add rustls features; if http only, leave as-is. Check with `grep -rn 'https://' engine/sdks/rust/api-full/src/`.\n- `engine/sdks/rust/api-full/rust/Cargo.toml:15`: same as above, duplicate path. Apply same treatment.\n- `rivetkit-rust/packages/client/Cargo.toml:17`: already uses `rustls-tls-native-roots` + `rustls-tls-webpki-roots`. Do NOT touch.\n- Workspace `Cargo.toml`: `[workspace.dependencies.reqwest] version = \"0.12.22\", features = [\"json\"]` — missing `default-features = false` AND missing rustls features. THIS IS THE PRIMARY FIX SITE (grep for `workspace.dependencies.reqwest`, ~line 280ish).\n\n===== VENDORED OPENSSL: BACK IT OUT =====\n\nCommit `f43bc26e8` on this branch added vendored openssl for `aarch64-linux-gnu` as a tactical workaround. That is superseded by this rustls fix. Do NOT revert the commit. Instead, delete the block at the bottom of `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml`:\n\n [target.'cfg(all(target_arch = \"aarch64\", target_env = \"gnu\"))'.dependencies]\n openssl = { version = \"0.10\", features = [\"vendored\"] }\n\nDelete that block AND the preceding comment block. Make the final tree correct; let the reviewer read the diff.\n\n===== WHAT TO DO =====\n\n1. In `/tmp/rivet-publish-fix/Cargo.toml` update the workspace reqwest dep (~line 280ish; grep for `workspace.dependencies.reqwest`):\n```toml\n[workspace.dependencies.reqwest]\nversion = \"0.12.22\"\ndefault-features = false\nfeatures = [\"json\", \"rustls-tls-native-roots\", \"rustls-tls-webpki-roots\"]\n```\nMatch the feature set `tokio-tungstenite` already uses. Don't add `http2` / `charset` unless `cargo tree` shows something needs them.\n\n2. Audit `engine/sdks/rust/api-full` (both Cargo.toml paths). If the crate hits https, add the same rustls features. If http-only (internal service?), leave as-is. Check with `grep -rn 'https://' engine/sdks/rust/api-full/src/`.\n\n3. Remove the vendored-openssl block from `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml` (described above).\n\n4. Update `/tmp/rivet-publish-fix/CLAUDE.md` — add a new short section after `## Async Rust Locks` (~line 161) OR alongside the existing TLS trust roots reference. Style: one-line bullets only (per the `## CLAUDE.md conventions` section):\n```\n## TLS / HTTP clients\n\n- Always use rustls. Never enable `native-tls` / `default-tls` on `reqwest` or anything else on Linux. Consumers (especially `.node` addons published via npm) must have no runtime `libssl.so` dependency.\n- `reqwest` workspace dep must set `default-features = false` and enable `rustls-tls-native-roots` + `rustls-tls-webpki-roots`. Per-crate overrides must keep the same.\n- Never vendor openssl as a workaround. If `openssl-sys` shows up in `cargo tree`, trace the transitive dep (usually `reqwest` default features) and switch it to rustls.\n```\n\n5. Verify with `cargo tree` for each of these packages:\n```bash\ncd /tmp/rivet-publish-fix\nfor p in rivetkit-napi rivetkit-core rivet-envoy-client rivet-engine; do\n echo \"=== $p ===\"\n cargo tree -p $p -i openssl-sys 2>&1 | head -5\n cargo tree -p $p -i native-tls 2>&1 | head -5\ndone\n```\nExpected: `package 'openssl-sys' not found` / `package 'native-tls' not found` for each (this `not found` phrasing is the success signal, not a failure). Anything else means something still pulls native-tls and needs a per-crate override.\n\n6. Commit + push from `/tmp/rivet-publish-fix`:\n - Commit 1 (primary): `feat(deps): switch reqwest to rustls workspace-wide, drop openssl`.\n - Commit 2 (docs): `docs(claude): require rustls for all HTTP/TLS clients`.\n - Optionally fold the openssl-removal into commit 1.\n - Push.\n\n7. Monitor the publish workflow on the new SHA:\n```bash\ngh run list --workflow publish.yaml --branch 04-22-chore_fix_remaining_issues_with_rivetkit-core --limit 1\n```\nPoll until `status=completed`. All 15 jobs should remain green (prior run on `3823a5f13` was fully green).\n\n8. Re-run the sanity-check skill on the new pkg-pr-new version:\n - Skill: `/home/nathan/r5/.claude/skills/sanity-check/SKILL.md`.\n - pkg-pr-new version format: `0.0.0-pr.4701.`. Pull the exact version from the publish run log (grep `gh run view --job --log | grep 'Bump package versions for build' -A1`) — sha length may differ from `git rev-parse --short HEAD`.\n - Copy `examples/hello-world/src` + `tsconfig.json` into a temp dir; install the two deps; run `test.mjs`.\n - The prior failure (`libssl.so.1.1: cannot open shared object file`) must be gone.\n - Belt-and-suspenders: `ldd` on the resulting `.node` should show NO `libssl` / `libcrypto` lines.\n\n===== REPO CONVENTIONS (from `/home/nathan/r5/CLAUDE.md`) =====\n\n- Hard tabs in Rust.\n- Conventional single-line commit messages, no co-author: `chore(pkg): foo`.\n- Do NOT run `cargo fmt` or `./scripts/cargo/fix.sh`.\n- CLAUDE.md additions: one-line bullets only, no paragraphs (per the `## CLAUDE.md conventions` section).\n- Trust boundary context: client↔engine is untrusted; TLS choice matters for actor/runner handshakes AND outbound metrics.\n\n===== GOTCHAS =====\n\n- `cargo tree` success phrasing is `error: package 'X' not found (in dependency graph)` — that IS the success signal.\n- Pre-commit hook runs lefthook (cargo-lock, cargo-fmt check, pnpm-lock).

Use `request_save_and_wait(...)` when the caller must observe save-request delivery failures. +- `pnpm -F rivetkit check-types` compiles every file under `rivetkit-typescript/packages/rivetkit/src/**/*`, not just tsup entrypoints. Exclude dead legacy sources in `tsconfig.json` or they will block unrelated stories. +- `getOrCreate` is only truly "ready" once the runtime adapter has acked its startup preamble. If core replies before that, the first action can beat `onWake` or `run` startup and read stale state. +- Keep the root `*ContextOf` helper surface synced across `rivetkit-typescript/packages/rivetkit/src/actor/contexts/index.ts`, the `src/actor/mod.ts` re-export list, and the docs pages `website/src/content/docs/actors/types.mdx` and `website/src/content/docs/actors/index.mdx`. +- Keep the TypeScript `ActorKey` and `ActorContext.key` surfaces string-only unless `client/query.ts`, key serialization, and gateway query parsing are widened end to end in the same change. +- Native adapter required-path config failures in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` should throw structured `RivetError`s, not plain `Error`, so `group` and `code` survive the bridge back to callers. +- Driver `actor_ready_timeout` failures can hide underlying `no_envoys` scheduling errors. Check actor lookup logs before assuming the bug is only in the transport or reply path. +- In `rivetkit-typescript/packages/rivetkit/tests/`, keep each `vi.waitFor(...)` reason on the immediately preceding `//` line. `pnpm run check:wait-for-comments` only enforces adjacency, so the comment still needs to explain the async reason for polling. +- When a driver test has a real event boundary, wait on a captured Promise or event collector instead of wrapping the action itself in `vi.waitFor(...)`. Reserve polling for state changes that have no direct hook. +- Bare `test.skip(...)` in `rivetkit-typescript/packages/rivetkit/tests/` needs an adjacent `// TODO(): ...` comment. `pnpm run check:test-skips` enforces that policy. +- Native `saveState` persistence coverage should live in driver tests with a real actor plus `hardCrashActor` and an observer actor; do not mock `NativeActorContext` for that path. +- When a TypeScript test needs deterministic monotonic time, patch `globalThis.performance.now` on the existing object. Replacing `globalThis.performance` can miss code that already captured the original object reference. +- In `rivetkit-core/tests/modules/task.rs`, any test that installs a tracing subscriber with `set_default(...)` needs `test_hook_lock()` first or full `cargo test` parallelism makes the log capture flaky. +- Intentional `rivetkit` package-surface removals should be documented in the root `CHANGELOG.md` with a direct before/after migration snippet, not left implicit in the code diff. +- Before deleting a `rivetkit/*` package export, grep `examples/`, `website/`, and `frontend/` for self-imports; docs and app code often still depend on those subpaths even after internal refactors. +- Use rustls for Rust HTTP/TLS clients; `reqwest`, Hyper clients, and published NAPI paths must not pull `native-tls`, `openssl-sys`, `libssl`, or `libcrypto`. +- Do not run the long `actor-lifecycle.test.ts` driver verifier in parallel with heavy Rust builds or `cargo test`; the extra load can trigger bogus `guard.actor_ready_timeout` failures in lifecycle race tests. +- NAPI lifecycle `ready`/`started` flags must forward to core `ActorContext`; do not keep a second copy in `ActorContextShared` or sleep gating drifts between layers. +- JS-only native actor caches in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` should live on `ActorContext.runtimeState()`, not on actorId-keyed module globals. Same-key recreates must get a fresh bag. +- Actor-connect WebSocket setup failures should send a protocol `Error` frame before closing; JSON/CBOR connection-level errors must include `actionId: null`. +- Actor-connect WebSocket setup also needs a registry-level timeout; the HTTP upgrade can finish before `connection_open` replies, so wedged setup must emit a structured error and close instead of idling until the client times out. +- Flush the envoy `WebSocketSender` after queueing required setup/error frames and before an immediate close, so the outgoing task handles the frame before termination. +- Actor-connect protocol `actionId` values are nullable; `0` is a valid action ID, and only `null` means a connection-level error. +- Gateway actor-connect must preserve tunnel messages queued between the envoy open ack and the websocket forwarding task; setup-error close frames can arrive immediately after open. +- If an omitted optional value passes in bare but fails in CBOR or JSON, inspect whether the cross-encoding path is coercing `undefined` into `null`. +- Opaque user payloads that must preserve JS `undefined` through Rust JSON/CBOR bridges should use `encodeCborCompat` / `decodeCborCompat`; do not run structural request envelopes through those helpers or optional API fields turn into bogus sentinel arrays. +- When validating Linux NAPI preview packages, run the sanity check in Docker `node:22` if the host already has a `rivet-engine` on port `6420`. +- Serverless `/start` driver tests need the start payload actor ID to exist in the same engine namespace as the serverless envoy headers, or startup fails at KV load with `actor does not exist`. +- Serverless `/start` tests must upsert a normal runner config for the temporary pool before starting the native serverless envoy. +- Raw `db()` uses the native database provider only; custom raw database client overrides are removed. +- Queue enqueue-and-wait must register the completion waiter before publishing the queue message to KV; otherwise a fast consumer can complete the message before the waiter exists. +- If Rust under `rivetkit-core` changes, make sure the local NAPI `.node` artifact is newer than the changed Rust files before rerunning driver tests. +- A driver story is not really dead until the matrix-shaped fast/slow verifier stays green; if the exact same file/test regresses there, reopen the existing story instead of spawning a duplicate. +- DT-008 verifier sweeps should use the explicit fast/slow driver file lists from the progress buckets; `tests/driver -t "static registry.*encoding \(bare\)"` is broader and muddies the counts. +- Close a stale driver story only after the exact targeted repro, the whole driver file, the relevant matrix slice, and typecheck all pass on the current branch. +- Native dispatch cancellation should flow as `CancellationToken` objects from NAPI TSF payloads into `registry/native.ts`. Do not reintroduce BigInt token registries or polling loops for cancel propagation. +- Clean `run` exit is not terminal in `rivetkit-core`; the actor generation must stay alive until the guaranteed `Stop` drives `SleepGrace` or `DestroyGrace`, and only then may it become `Terminated`. +- SQLite v2 shrink paths must delete above-EOF PIDX rows and fully-above-EOF SHARD blobs in the same commit or takeover transaction; compaction only cleans partial shards by filtering pages at or below `head.db_size_pages`. +- A fresh `CommandStartActor`/Allocate is authoritative for a crashed v1 SQLite migration; reset staged v1 rows immediately on restart instead of waiting for the stale-owner lease to expire. +- `getForId(actorId)` teardown assertions in driver tests are real but slow because actor lookup polls until the registry drops the actor; use them when you specifically need post-destroy unreachability, not as casual filler. +- Native database providers in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` must close on sleep via `closeDatabase(false)` after user `onSleep`, or provider `onDestroy` cleanup runs on destroy only and lifecycle cleanup tests stick at `0`. + +## 2026-04-23T11:45:04Z - DT-000 +- Implemented the urgent Linux NAPI publish fix in `/tmp/rivet-publish-fix` on branch `04-22-chore_fix_remaining_issues_with_rivetkit-core`. +- Switched workspace `reqwest` to rustls with default features disabled, replaced direct `hyper-tls` users with `hyper-rustls`, and removed the vendored OpenSSL block from `rivetkit-napi`. +- Added `CLAUDE.md` TLS rules requiring rustls and forbidding vendored OpenSSL workarounds. +- Files changed: `Cargo.toml`, `Cargo.lock`, `engine/packages/pools/{Cargo.toml,src/db/clickhouse.rs}`, `engine/packages/guard-core/{Cargo.toml,src/proxy_service.rs}`, `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml`, `CLAUDE.md`. +- Verification: `cargo tree -p {rivetkit-napi,rivetkit-core,rivet-envoy-client,rivet-engine} -i {openssl-sys,native-tls}` returned Cargo's package-not-found success signal;

Needs a plan to actually run the suite.\n\n===== ARCHITECTURAL CONTEXT =====\n\n- rivetkit-core (Rust) owns all lifecycle/state/dispatch state machine.\n- rivetkit-napi (Rust) is the NAPI binding layer; no load-bearing logic.\n- rivetkit (TypeScript) is the user-facing SDK; owns workflow engine, agent-os, client library, and Zod validation.\n- CBOR at all cross-language boundaries. JSON only for HTTP inspector endpoints.\n- Errors cross boundaries as universal `RivetError` (group/code/message/metadata).\n\n===== INVARIANTS =====\n\n- Every story must root-cause the failure; no retry-loop flake masking. Tests that time out at 30s almost always indicate a bug in core/napi/typescript that never completes or never surfaces an error, not a 'slow test' that needs a longer timeout.\n- Never use `vi.mock`, `jest.mock`, or module-level mocking; tests run against real infrastructure.\n- Every `vi.waitFor` call must have a one-line comment explaining why polling is necessary.\n- Errors thrown in core/napi/typescript paths must reach the client as structured `RivetError` (group/code/message/metadata) through the relevant transport (WebSocket, HTTP, SSE).\n- If the failure reveals a missing enforcement in core, fix in core (not TS). If it reveals missing translation at the NAPI boundary, fix in NAPI. TS fixes only if the test is itself wrong OR the logic is TS-only (workflow engine, Zod validation).\n\n===== RUN COMMANDS =====\n\nFrom repo root:\n\n- Build TS: `pnpm build -F rivetkit`.\n- Build NAPI (only when Rust under rivetkit-napi or sqlite-native changes): `pnpm --filter @rivetkit/rivetkit-napi build:force`.\n- Targeted driver test (single test): `pnpm -F rivetkit test tests/driver/.test.ts -t \"\"`.\n- Whole driver test file: `pnpm -F rivetkit test tests/driver/.test.ts`.\n- Per `.claude/reference/testing.md`: prefer the single test file via its filename and the `-t` filter while iterating. Verification must run the full file without `-t`.\n\n===== ACCEPTANCE RULE FOR EVERY STORY =====\n\nEvery story MUST include, as acceptance criteria, that the ENTIRE relevant test file (not just the single `-t` filter) passes under the static/http/bare matrix. Individual-test filtered runs are fine while iterating, but verification uses the whole file so we catch regressions in sibling tests introduced by the fix.\n\n===== READ BEFORE STARTING =====\n\n- `.agent/notes/driver-test-progress.md` — the failure log this PRD works from.\n- `CLAUDE.md` at repo root — layer constraints, error handling rules, fail-by-default runtime rules.\n- `rivetkit-typescript/CLAUDE.md` — tree-shaking boundaries, raw KV limits, workflow context guards, NAPI receive loop invariants.\n- `.claude/reference/testing.md` — Vitest filter gotchas, driver-test parity workflow.", + "project": "sqlite-storage-stateless", + "branchName": "ralph/sqlite-storage-stateless", + "description": "Rewrite the SQLite v2 storage engine to be stateless on the actor side (pegboard-envoy) and move compaction to a separate, stateful HPA-scaled service. Hot-path ops collapse to two RPCs (`get_pages`, `commit`) with no `open`/`close` lifecycle, no fence inputs on the wire, and pegboard exclusivity as the only writer fence. Compaction triggers go through UPS (queue-group balanced) and use a UDB-backed `/META/compactor_lease` to prevent concurrent compactions. META splits into four sub-keys (`/META/head`, `/META/compact`, `/META/quota`, `/META/compactor_lease`) so commit and compaction never conflict on the same key. Quota is an FDB atomic-add counter at `/META/quota`; the cap (10 GiB) is a Rust constant, enforced via an in-memory cache loaded lazily on the first UDB tx. Spec lives at `.agent/specs/sqlite-storage-stateless.md`. Read the spec first.\n\n===== KEY INVARIANTS =====\n\n- Actor-side (pegboard-envoy) is stateless. No `open`/`close`, no per-conn `active_actors` HashMap, no presence tracking. Only per-conn state is a perf-only `scc::HashMap>` populated lazily by SQLite request handlers.\n- The crate exports a single per-actor type `ActorDb`. No `Pump` struct, no process-wide registry, no per-conn wrapper inside sqlite-storage.\n- Pegboard exclusivity is the only writer fence in release. Defensive in-tx checks for 'two writers detected' are `#[cfg(debug_assertions)]` only.\n- No takeover work in release. Pegboard's reassignment transaction does not touch sqlite-storage. Lazy first-commit META init seeds `/META/head` if absent. Debug builds run `takeover::reconcile` for invariant verification only (no cleanup).\n- META sub-keys: `/META/head` (commit-owned, vbare), `/META/compact` (compaction-owned, vbare), `/META/quota` (raw i64 LE atomic counter), `/META/compactor_lease` (vbare).\n- `/META/quota` is fixed-width i64 LE. FDB atomic-add is exact integer addition (no drift). Mismatch = bug at the call site.\n- Quota cap is a Rust constant: `SQLITE_MAX_STORAGE_BYTES = 10 * 1024 * 1024 * 1024` in `pump::quota`. No `/META/static` key; remove it entirely.\n- Compactor service is `ServiceKind::Standalone` registered in `engine/packages/engine/src/run_config.rs`, same pattern as `pegboard_outbound`. UPS queue-group `\"compactor\"` balances work across pods.\n- Lease lifecycle uses a local timer + cancellation token + periodic renewal task. No `/META/compactor_lease` reads inside compaction work transactions.\n- PIDX deletes use FDB `COMPARE_AND_CLEAR` to resolve commit-vs-compaction races without taking conflict ranges.\n- Per-actor compaction trigger throttle (500ms window, 30s safety net). First trigger fires immediately; subsequent ones in the window are dropped. This is throttle, not debounce.\n- Breaking changes are unconditionally acceptable. The system has not shipped to production. Wire shape, on-disk key layout, and `DBHead`/META schema are all free to change.\n\n===== ARCHITECTURAL CONTEXT =====\n\n- Single crate `engine/packages/sqlite-storage/` with two top-level modules (`pump/` and `compactor/`) plus a top-level `takeover.rs`.\n- `pump/` is the hot path. Used by pegboard-envoy. Exports `ActorDb`.\n- `compactor/` is the background service. Registered as a Standalone service.\n- `takeover.rs` is debug-only invariant verification. Not compiled in release.\n- The legacy crate gets renamed to `sqlite-storage-legacy` for reference during the rewrite, then deleted in the final stage.\n- All tests live under `tests/` (no inline `#[cfg(test)] mod tests` in `src/`).\n- Metrics use `lazy_static!` global statics. All metrics include a `node_id` label sourced from `pools.node_id()` (see US-001).\n\n===== RUN COMMANDS =====\n\nFrom repo root:\n\n- Compile-check a crate: `cargo check -p ` (preferred for verification).\n- Build a crate: `cargo build -p `.\n- Run all tests for a crate: `cargo test -p `.\n- Run a single test file: `cargo test -p sqlite-storage --test `.\n- Run a single test: `cargo test -p -- --nocapture`.\n- Never run `cargo fmt` or `./scripts/cargo/fix.sh` — the team formats at merge time.\n\n===== READ BEFORE STARTING =====\n\n- `.agent/specs/sqlite-storage-stateless.md` — the full spec this PRD implements.\n- `engine/CLAUDE.md` — VBARE migration rules, Epoxy keys, SQLite storage tests, Pegboard Envoy notes.\n- `CLAUDE.md` at repo root — layer constraints, fail-by-default rules, async lock rules, error handling.\n- `docs-internal/engine/sqlite-storage.md` — current SQLite storage crash course (META/PIDX/DELTA/SHARD layout, read/write/compaction paths).\n- `docs-internal/engine/sqlite-vfs.md` — VFS parity rules.\n- `engine/packages/sqlite-storage/src/` — legacy code to lift from (after Stage 1 rename, this will be `sqlite-storage-legacy`).\n- `engine/packages/pegboard-outbound/src/lib.rs` — reference pattern for Standalone service registration.\n- `engine/packages/pegboard/src/actor_kv/` — reference for namespace-level metering pipeline (MetricKey, KV_BILLABLE_CHUNK).", "userStories": [ { - "id": "DT-001", - "title": "Fix actor-conn: reject request exceeding maxIncomingMessageSize", - "description": "`tests/driver/actor-conn.test.ts:652` (`should reject request exceeding maxIncomingMessageSize`) times out at 30s.

Scope is the `rivetkit-typescript/` workspace, with PRIMARY focus on `packages/rivetkit/package.json`. Secondary focus: every other published package in `rivetkit-typescript/packages/*/package.json` (not the fixture/example packages and not `rivetkit-napi` native build deps).\n\nGoal: the `dependencies` field of each PUBLISHED package should list ONLY what its runtime source code actually imports under `src/` at runtime. Everything else gets deleted outright, moved to `devDependencies`, or moved to `peerDependencies` (with an explicit reason).\n\nCURRENT DEPENDENCIES of `packages/rivetkit` to audit (direct runtime deps list):\n\n- `@hono/node-server`, `@hono/node-ws`, `@hono/zod-openapi`\n- `@rivet-dev/agent-os-core`\n- `@rivetkit/bare-ts`, `@rivetkit/engine-cli`, `@rivetkit/engine-envoy-protocol`\n- `@rivetkit/rivetkit-napi`, `@rivetkit/traces`, `@rivetkit/virtual-websocket`, `@rivetkit/workflow-engine`\n- `cbor-x`, `get-port`, `hono`, `invariant`, `p-retry`, `pino`, `uuid`, `vbare`, `zod`\n- peerDependencies: `drizzle-kit`, `eventsource`, `ws`\n\nMETHOD (do this for every published package in `rivetkit-typescript/packages/*`):\n\n1. For each declared dependency `X`, run a search for any runtime import — `import ... from \"X\"` or `require(\"X\")` or `import(\"X\")` — across `src/` of that package. Ignore matches in `tests/`, `fixtures/`, `scripts/`, `docs/`, `*.test.ts`, `*.spec.ts`, `vitest.config.*`, `tsup.config.*`, and build config files. Skip type-only imports from `@types/*` — those should be devDependencies.\n2. Categorize each dep into one of:\n - `RUNTIME` — imported by code under `src/` that ships in the built output. Keep in `dependencies`.\n - `DEV-ONLY` — only used by tests, fixtures, build tooling, scripts, or codegen. MOVE to `devDependencies`.\n - `PEER` — consumers are expected to install this themselves (optional adapters like drizzle/eventsource/ws). Keep or promote to `peerDependencies` (mark optional if appropriate).\n - `UNUSED` — no runtime AND no dev-tool caller anywhere in the package. DELETE.\n3. For tree-shakeable optional subpaths (e.g. things gated behind a specific import entrypoint such as `rivetkit/workflow` or `rivetkit/db`), confirm the import graph is tree-shake-clean: importing the main entrypoint must not pull the optional dep. If it does, fix imports before demoting.\n4. Respect `rivetkit-typescript/CLAUDE.md`'s tree-shaking boundaries:\n - `@rivetkit/workflow-engine` must not be imported outside the `rivetkit/workflow` entrypoint.\n - SQLite runtime must stay on `@rivetkit/rivetkit-napi`; do NOT reintroduce WASM SQLite.\n - `rivetkit/db` is the opt-in for SQLite.\n - Core drivers remain SQLite-agnostic.\n5. For each dep you move or delete, write a one-line justification in the story's final progress note in `.agent/notes/dep-audit-rivetkit-typescript.md` (new file). Format: `| package | dep | decision | reason |` table.\n\nCONSTRAINTS:\n\n- Do NOT break any driver tests. Run the static/http/bare fast + slow driver suites end-to-end before marking this story `passes: true`.\n- Do NOT rewrite functionality just to shed a dep. If a dep is load-bearing, leave it alone and note it.\n- Do NOT touch native build-time deps in `packages/rivetkit-napi/package.json` (napi-rs, Cargo deps via `build:force`).\n- Peer-dep changes are user-visible. Each peer-dep addition or promotion needs a one-line CHANGELOG entry in the package.\n\nINCLUDE IN SCOPE: every published package.

READ THAT SPEC FIRST. This story supersedes the deleted `handler-serve-restoration.md` spec; the old TS-reverse-proxy approach was wrong.\n\nCORE INSIGHT: `.handler()` is not a user-traffic gateway. It is the four-route serverless runner endpoint (`GET /`, `GET /health`, `GET /metadata`, `POST /start`) that the engine calls to wake a runner inside a serverless function's request lifespan. The meaningful route is `POST /start`, which accepts a binary envoy-protocol payload, opens an SSE stream back to the engine, calls `envoy.start_serverless_actor(payload)`, and keeps the SSE alive with pings until the envoy stops or the request aborts.\n\nLAYER SPLIT (per spec section 'Architecture'):\n\n1. `rivetkit-core` (Rust) gets a new `serverless` module owning: URL routing for `/api/rivet/*` (configurable base path), `x-rivet-{endpoint,token,pool-name,namespace}` header parsing, endpoint/namespace validation (port `normalizeEndpointUrl` + `endpointsMatch` + regional-hostname logic from `feat/sqlite-vfs-v2:rivetkit-typescript/packages/rivetkit/src/serverless/router.ts` with identical behavior + unit tests), envoy startup reuse, `envoy.start_serverless_actor(payload)` invocation, SSE framing + ping keepalive loop, abort propagation. Single entrypoint: `async fn handle_request(req: ServerlessRequest) -> ServerlessResponseStream`. Rust-only; no NAPI changes yet in this step — core comes first with Rust tests.\n\n2. `rivetkit-napi` exposes exactly one new method: `CoreRegistry.handleServerlessRequest({ method, url, headers, body: Buffer }, { writeChunk, endStream }, abortSignal)`. Returns `Promise<{ status, headers }>`; body chunks flow through `writeChunk` TSF callback; stream terminates via `endStream` (with optional `{ group, code, message }` on error); abort via the passed `AbortSignal` hooked through the existing `cancellation_token.rs` TSF pattern. Thin binding; no logic.\n\n3. `rivetkit-typescript/packages/rivetkit`: `Registry.handler(req)` builds the NAPI payload, creates a `ReadableStream` whose controller is fed by `writeChunk` + closed by `endStream`, returns `new Response(stream, { status, headers })`. `Registry.serve()` returns `{ fetch: (req) => this.handler(req) }`. Drop the `removedLegacyRoutingError` throws from `src/registry/index.ts:75-95`.\n\nSTREAMING SHAPE:\n- Response body streams from Rust to JS via a `ThreadsafeFunction` (`writeChunk`). Core writes pre-framed SSE bytes (e.g. `event: ping\\ndata:\\n\\n`); TS never parses SSE.\n- Request body is a single `Buffer` (CBOR-wrap `{method, url, headers, body}` once on the TS side; pass the Buffer through to Rust without per-chunk inbound streaming — `/start` payloads are bounded and read-once).\n- `req.signal` forwarded as `abortSignal`. `ReadableStream` cancel callback calls a NAPI `cancel()` to stop the Rust SSE loop.\n\nHIGH-LEVEL `registry.start()`:\n- Three-line convenience: `await startEnvoy(); printWelcome();`. The engine subprocess already binds user-facing ports when `startEngine: true`.\n- Static-file serving: check if the engine subprocess already has a `staticDir` flag. If yes, wire `RegistryConfig.staticDir` through to the engine args. If no, document the gap in CHANGELOG and punt to a follow-up story.\n- No new HTTP listeners in rivetkit-typescript.\n\nSCOPE / EXCLUSIONS:\n- Node primary (Bun should also work since it supports NAPI + standard `fetch`/`Response`). Cloudflare Workers / Deno are OUT of scope for v1 (NAPI doesn't load on V8-only runtimes).\n- Inbound request-body streaming is out of scope (bounded `/start` payload only).\n- Response streaming is SSE only in v1 (same framing as old `streamSSE`).

Build host is `rust:1.89.0-bullseye` (Debian 11, OpenSSL 1.1); consumer hosts on Bookworm+/Ubuntu 22.04+/RHEL 9+ have `libssl.so.3`. Every modern Linux consumer is broken.\n\n===== ROOT CAUSE =====\n\nThe `.node` is a pre-compiled blob. The `openssl` dep is not in any npm tree — it was baked in at Rust build time via:\n\n rivetkit-napi → rivetkit-core → rivet-pools → rivet-metrics\n → opentelemetry-otlp → opentelemetry-http\n → reqwest (default features → default-tls → native-tls on Linux → openssl-sys)\n\nEverything else in the workspace already uses rustls (tokio-tungstenite configured with rustls features; `rivetkit-rust/packages/client` explicitly passes rustls). The workspace-level `reqwest` is the leak — it does NOT set `default-features = false`, so every transitive user gets the native-tls default.\n\n===== EXISTING REQWEST USAGES (AUDIT) =====\n\n- `engine/sdks/rust/api-full/Cargo.toml:15`: `reqwest = { version = \"^0.12\", default-features = false, features = [\"json\", \"multipart\"] }` — no TLS features. If the crate makes https calls, add rustls features; if http only, leave as-is. Check with `grep -rn 'https://' engine/sdks/rust/api-full/src/`.\n- `engine/sdks/rust/api-full/rust/Cargo.toml:15`: same as above, duplicate path. Apply same treatment.\n- `rivetkit-rust/packages/client/Cargo.toml:17`: already uses `rustls-tls-native-roots` + `rustls-tls-webpki-roots`. Do NOT touch.\n- Workspace `Cargo.toml`: `[workspace.dependencies.reqwest] version = \"0.12.22\", features = [\"json\"]` — missing `default-features = false` AND missing rustls features. THIS IS THE PRIMARY FIX SITE (grep for `workspace.dependencies.reqwest`, ~line 280ish).\n\n===== VENDORED OPENSSL: BACK IT OUT =====\n\nCommit `f43bc26e8` on this branch added vendored openssl for `aarch64-linux-gnu` as a tactical workaround. That is superseded by this rustls fix. Do NOT revert the commit. Instead, delete the block at the bottom of `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml`:\n\n [target.'cfg(all(target_arch = \"aarch64\", target_env = \"gnu\"))'.dependencies]\n openssl = { version = \"0.10\", features = [\"vendored\"] }\n\nDelete that block AND the preceding comment block. Make the final tree correct; let the reviewer read the diff.\n\n===== WHAT TO DO =====\n\n1. In `/tmp/rivet-publish-fix/Cargo.toml` update the workspace reqwest dep (~line 280ish; grep for `workspace.dependencies.reqwest`):\n```toml\n[workspace.dependencies.reqwest]\nversion = \"0.12.22\"\ndefault-features = false\nfeatures = [\"json\", \"rustls-tls-native-roots\", \"rustls-tls-webpki-roots\"]\n```\nMatch the feature set `tokio-tungstenite` already uses. Don't add `http2` / `charset` unless `cargo tree` shows something needs them.\n\n2. Audit `engine/sdks/rust/api-full` (both Cargo.toml paths). If the crate hits https, add the same rustls features. If http-only (internal service?), leave as-is. Check with `grep -rn 'https://' engine/sdks/rust/api-full/src/`.\n\n3. Remove the vendored-openssl block from `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml` (described above).\n\n4. Update `/tmp/rivet-publish-fix/CLAUDE.md` — add a new short section after `## Async Rust Locks` (~line 161) OR alongside the existing TLS trust roots reference. Style: one-line bullets only (per the `## CLAUDE.md conventions` section):\n```\n## TLS / HTTP clients\n\n- Always use rustls. Never enable `native-tls` / `default-tls` on `reqwest` or anything else on Linux. Consumers (especially `.node` addons published via npm) must have no runtime `libssl.so` dependency.\n- `reqwest` workspace dep must set `default-features = false` and enable `rustls-tls-native-roots` + `rustls-tls-webpki-roots`. Per-crate overrides must keep the same.\n- Never vendor openssl as a workaround. If `openssl-sys` shows up in `cargo tree`, trace the transitive dep (usually `reqwest` default features) and switch it to rustls.\n```\n\n5. Verify with `cargo tree` for each of these packages:\n```bash\ncd /tmp/rivet-publish-fix\nfor p in rivetkit-napi rivetkit-core rivet-envoy-client rivet-engine; do\n echo \"=== $p ===\"\n cargo tree -p $p -i openssl-sys 2>&1 | head -5\n cargo tree -p $p -i native-tls 2>&1 | head -5\ndone\n```\nExpected: `package 'openssl-sys' not found` / `package 'native-tls' not found` for each (this `not found` phrasing is the success signal, not a failure). Anything else means something still pulls native-tls and needs a per-crate override.\n\n6. Commit + push from `/tmp/rivet-publish-fix`:\n - Commit 1 (primary): `feat(deps): switch reqwest to rustls workspace-wide, drop openssl`.\n - Commit 2 (docs): `docs(claude): require rustls for all HTTP/TLS clients`.\n - Optionally fold the openssl-removal into commit 1.\n - Push.\n\n7. Monitor the publish workflow on the new SHA:\n```bash\ngh run list --workflow publish.yaml --branch 04-22-chore_fix_remaining_issues_with_rivetkit-core --limit 1\n```\nPoll until `status=completed`. All 15 jobs should remain green (prior run on `3823a5f13` was fully green).\n\n8. Re-run the sanity-check skill on the new pkg-pr-new version:\n - Skill: `/home/nathan/r5/.claude/skills/sanity-check/SKILL.md`.\n - pkg-pr-new version format: `0.0.0-pr.4701.`. Pull the exact version from the publish run log (grep `gh run view --job --log | grep 'Bump package versions for build' -A1`) — sha length may differ from `git rev-parse --short HEAD`.\n - Copy `examples/hello-world/src` + `tsconfig.json` into a temp dir; install the two deps; run `test.mjs`.\n - The prior failure (`libssl.so.1.1: cannot open shared object file`) must be gone.\n - Belt-and-suspenders: `ldd` on the resulting `.node` should show NO `libssl` / `libcrypto` lines.\n\n===== REPO CONVENTIONS (from `/home/nathan/r5/CLAUDE.md`) =====\n\n- Hard tabs in Rust.\n- Conventional single-line commit messages, no co-author: `chore(pkg): foo`.\n- Do NOT run `cargo fmt` or `./scripts/cargo/fix.sh`.\n- CLAUDE.md additions: one-line bullets only, no paragraphs (per the `## CLAUDE.md conventions` section).\n- Trust boundary context: client↔engine is untrusted; TLS choice matters for actor/runner handshakes AND outbound metrics.\n\n===== GOTCHAS =====\n\n- `cargo tree` success phrasing is `error: package 'X' not found (in dependency graph)` — that IS the success signal.\n- Pre-commit hook runs lefthook (cargo-lock, cargo-fmt check, pnpm-lock).

Use `request_save_and_wait(...)` when the caller must observe save-request delivery failures. -- `pnpm -F rivetkit check-types` compiles every file under `rivetkit-typescript/packages/rivetkit/src/**/*`, not just tsup entrypoints. Exclude dead legacy sources in `tsconfig.json` or they will block unrelated stories. -- `getOrCreate` is only truly "ready" once the runtime adapter has acked its startup preamble. If core replies before that, the first action can beat `onWake` or `run` startup and read stale state. -- Keep the root `*ContextOf` helper surface synced across `rivetkit-typescript/packages/rivetkit/src/actor/contexts/index.ts`, the `src/actor/mod.ts` re-export list, and the docs pages `website/src/content/docs/actors/types.mdx` and `website/src/content/docs/actors/index.mdx`. -- Keep the TypeScript `ActorKey` and `ActorContext.key` surfaces string-only unless `client/query.ts`, key serialization, and gateway query parsing are widened end to end in the same change. -- Native adapter required-path config failures in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` should throw structured `RivetError`s, not plain `Error`, so `group` and `code` survive the bridge back to callers. -- Driver `actor_ready_timeout` failures can hide underlying `no_envoys` scheduling errors. Check actor lookup logs before assuming the bug is only in the transport or reply path. -- In `rivetkit-typescript/packages/rivetkit/tests/`, keep each `vi.waitFor(...)` reason on the immediately preceding `//` line. `pnpm run check:wait-for-comments` only enforces adjacency, so the comment still needs to explain the async reason for polling. -- When a driver test has a real event boundary, wait on a captured Promise or event collector instead of wrapping the action itself in `vi.waitFor(...)`. Reserve polling for state changes that have no direct hook. -- Bare `test.skip(...)` in `rivetkit-typescript/packages/rivetkit/tests/` needs an adjacent `// TODO(): ...` comment. `pnpm run check:test-skips` enforces that policy. -- Native `saveState` persistence coverage should live in driver tests with a real actor plus `hardCrashActor` and an observer actor; do not mock `NativeActorContext` for that path. -- When a TypeScript test needs deterministic monotonic time, patch `globalThis.performance.now` on the existing object. Replacing `globalThis.performance` can miss code that already captured the original object reference. -- In `rivetkit-core/tests/modules/task.rs`, any test that installs a tracing subscriber with `set_default(...)` needs `test_hook_lock()` first or full `cargo test` parallelism makes the log capture flaky. -- Intentional `rivetkit` package-surface removals should be documented in the root `CHANGELOG.md` with a direct before/after migration snippet, not left implicit in the code diff. -- Before deleting a `rivetkit/*` package export, grep `examples/`, `website/`, and `frontend/` for self-imports; docs and app code often still depend on those subpaths even after internal refactors. -- Use rustls for Rust HTTP/TLS clients; `reqwest`, Hyper clients, and published NAPI paths must not pull `native-tls`, `openssl-sys`, `libssl`, or `libcrypto`. -- Do not run the long `actor-lifecycle.test.ts` driver verifier in parallel with heavy Rust builds or `cargo test`; the extra load can trigger bogus `guard.actor_ready_timeout` failures in lifecycle race tests. -- NAPI lifecycle `ready`/`started` flags must forward to core `ActorContext`; do not keep a second copy in `ActorContextShared` or sleep gating drifts between layers. -- JS-only native actor caches in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` should live on `ActorContext.runtimeState()`, not on actorId-keyed module globals. Same-key recreates must get a fresh bag. -- Actor-connect WebSocket setup failures should send a protocol `Error` frame before closing; JSON/CBOR connection-level errors must include `actionId: null`. -- Actor-connect WebSocket setup also needs a registry-level timeout; the HTTP upgrade can finish before `connection_open` replies, so wedged setup must emit a structured error and close instead of idling until the client times out. -- Flush the envoy `WebSocketSender` after queueing required setup/error frames and before an immediate close, so the outgoing task handles the frame before termination. -- Actor-connect protocol `actionId` values are nullable; `0` is a valid action ID, and only `null` means a connection-level error. -- Gateway actor-connect must preserve tunnel messages queued between the envoy open ack and the websocket forwarding task; setup-error close frames can arrive immediately after open. -- If an omitted optional value passes in bare but fails in CBOR or JSON, inspect whether the cross-encoding path is coercing `undefined` into `null`. -- Opaque user payloads that must preserve JS `undefined` through Rust JSON/CBOR bridges should use `encodeCborCompat` / `decodeCborCompat`; do not run structural request envelopes through those helpers or optional API fields turn into bogus sentinel arrays. -- When validating Linux NAPI preview packages, run the sanity check in Docker `node:22` if the host already has a `rivet-engine` on port `6420`. -- Serverless `/start` driver tests need the start payload actor ID to exist in the same engine namespace as the serverless envoy headers, or startup fails at KV load with `actor does not exist`. -- Serverless `/start` tests must upsert a normal runner config for the temporary pool before starting the native serverless envoy. -- Raw `db()` uses the native database provider only; custom raw database client overrides are removed. -- Queue enqueue-and-wait must register the completion waiter before publishing the queue message to KV; otherwise a fast consumer can complete the message before the waiter exists. -- If Rust under `rivetkit-core` changes, make sure the local NAPI `.node` artifact is newer than the changed Rust files before rerunning driver tests. -- A driver story is not really dead until the matrix-shaped fast/slow verifier stays green; if the exact same file/test regresses there, reopen the existing story instead of spawning a duplicate. -- DT-008 verifier sweeps should use the explicit fast/slow driver file lists from the progress buckets; `tests/driver -t "static registry.*encoding \(bare\)"` is broader and muddies the counts. -- Close a stale driver story only after the exact targeted repro, the whole driver file, the relevant matrix slice, and typecheck all pass on the current branch. -- Native dispatch cancellation should flow as `CancellationToken` objects from NAPI TSF payloads into `registry/native.ts`. Do not reintroduce BigInt token registries or polling loops for cancel propagation. -- Clean `run` exit is not terminal in `rivetkit-core`; the actor generation must stay alive until the guaranteed `Stop` drives `SleepGrace` or `DestroyGrace`, and only then may it become `Terminated`. -- SQLite v2 shrink paths must delete above-EOF PIDX rows and fully-above-EOF SHARD blobs in the same commit or takeover transaction; compaction only cleans partial shards by filtering pages at or below `head.db_size_pages`. -- A fresh `CommandStartActor`/Allocate is authoritative for a crashed v1 SQLite migration; reset staged v1 rows immediately on restart instead of waiting for the stale-owner lease to expire. -- `getForId(actorId)` teardown assertions in driver tests are real but slow because actor lookup polls until the registry drops the actor; use them when you specifically need post-destroy unreachability, not as casual filler. -- Native database providers in `rivetkit-typescript/packages/rivetkit/src/registry/native.ts` must close on sleep via `closeDatabase(false)` after user `onSleep`, or provider `onDestroy` cleanup runs on destroy only and lifecycle cleanup tests stick at `0`. - -## 2026-04-23T11:45:04Z - DT-000 -- Implemented the urgent Linux NAPI publish fix in `/tmp/rivet-publish-fix` on branch `04-22-chore_fix_remaining_issues_with_rivetkit-core`. -- Switched workspace `reqwest` to rustls with default features disabled, replaced direct `hyper-tls` users with `hyper-rustls`, and removed the vendored OpenSSL block from `rivetkit-napi`. -- Added `CLAUDE.md` TLS rules requiring rustls and forbidding vendored OpenSSL workarounds. -- Files changed: `Cargo.toml`, `Cargo.lock`, `engine/packages/pools/{Cargo.toml,src/db/clickhouse.rs}`, `engine/packages/guard-core/{Cargo.toml,src/proxy_service.rs}`, `rivetkit-typescript/packages/rivetkit-napi/Cargo.toml`, `CLAUDE.md`. -- Verification: `cargo tree -p {rivetkit-napi,rivetkit-core,rivet-envoy-client,rivet-engine} -i {openssl-sys,native-tls}` returned Cargo's package-not-found success signal;

Hot-path ops collapse to two RPCs (`get_pages`, `commit`) with no `open`/`close` lifecycle, no fence inputs on the wire, and pegboard exclusivity as the only writer fence. Compaction triggers go through UPS (queue-group balanced) and use a UDB-backed `/META/compactor_lease` to prevent concurrent compactions. META splits into four sub-keys (`/META/head`, `/META/compact`, `/META/quota`, `/META/compactor_lease`) so commit and compaction never conflict on the same key. Quota is an FDB atomic-add counter at `/META/quota`; the cap (10 GiB) is a Rust constant, enforced via an in-memory cache loaded lazily on the first UDB tx. Spec lives at `.agent/specs/sqlite-storage-stateless.md`. Read the spec first.\n\n===== KEY INVARIANTS =====\n\n- Actor-side (pegboard-envoy) is stateless. No `open`/`close`, no per-conn `active_actors` HashMap, no presence tracking. Only per-conn state is a perf-only `scc::HashMap>` populated lazily by SQLite request handlers.\n- The crate exports a single per-actor type `ActorDb`. No `Pump` struct, no process-wide registry, no per-conn wrapper inside sqlite-storage.\n- Pegboard exclusivity is the only writer fence in release. Defensive in-tx checks for 'two writers detected' are `#[cfg(debug_assertions)]` only.\n- No takeover work in release. Pegboard's reassignment transaction does not touch sqlite-storage. Lazy first-commit META init seeds `/META/head` if absent. Debug builds run `takeover::reconcile` for invariant verification only (no cleanup).\n- META sub-keys: `/META/head` (commit-owned, vbare), `/META/compact` (compaction-owned, vbare), `/META/quota` (raw i64 LE atomic counter), `/META/compactor_lease` (vbare).\n- `/META/quota` is fixed-width i64 LE. FDB atomic-add is exact integer addition (no drift). Mismatch = bug at the call site.\n- Quota cap is a Rust constant: `SQLITE_MAX_STORAGE_BYTES = 10 * 1024 * 1024 * 1024` in `pump::quota`. No `/META/static` key; remove it entirely.\n- Compactor service is `ServiceKind::Standalone` registered in `engine/packages/engine/src/run_config.rs`, same pattern as `pegboard_outbound`. UPS queue-group `\"compactor\"` balances work across pods.\n- Lease lifecycle uses a local timer + cancellation token + periodic renewal task. No `/META/compactor_lease` reads inside compaction work transactions.\n- PIDX deletes use FDB `COMPARE_AND_CLEAR` to resolve commit-vs-compaction races without taking conflict ranges.\n- Per-actor compaction trigger throttle (500ms window, 30s safety net). First trigger fires immediately; subsequent ones in the window are dropped. This is throttle, not debounce.\n- Breaking changes are unconditionally acceptable. The system has not shipped to production. Wire shape, on-disk key layout, and `DBHead`/META schema are all free to change.\n\n===== ARCHITECTURAL CONTEXT =====\n\n- Single crate `engine/packages/sqlite-storage/` with two top-level modules (`pump/` and `compactor/`) plus a top-level `takeover.rs`.\n- `pump/` is the hot path. Used by pegboard-envoy. Exports `ActorDb`.\n- `compactor/` is the background service. Registered as a Standalone service.\n- `takeover.rs` is debug-only invariant verification. Not compiled in release.\n- The legacy crate gets renamed to `sqlite-storage-legacy` for reference during the rewrite, then deleted in the final stage.\n- All tests live under `tests/` (no inline `#[cfg(test)] mod tests` in `src/`).\n- Metrics use `lazy_static!` global statics. All metrics include a `node_id` label sourced from `pools.node_id()` (see US-001).\n\n===== RUN COMMANDS =====\n\nFrom repo root:\n\n- Compile-check a crate: `cargo check -p ` (preferred for verification).\n- Build a crate: `cargo build -p `.\n- Run all tests for a crate: `cargo test -p `.\n- Run a single test file: `cargo test -p sqlite-storage --test `.\n- Run a single test: `cargo test -p -- --nocapture`.\n- Never run `cargo fmt` or `./scripts/cargo/fix.sh` — the team formats at merge time.\n\n===== READ BEFORE STARTING =====\n\n- `.agent/specs/sqlite-storage-stateless.md` — the full spec this PRD implements.\n- `engine/CLAUDE.md` — VBARE migration rules, Epoxy keys, SQLite storage tests, Pegboard Envoy notes.\n- `CLAUDE.md` at repo root — layer constraints, fail-by-default rules, async lock rules, error handling.\n- `docs-internal/engine/sqlite-storage.md` — current SQLite storage crash course (META/PIDX/DELTA/SHARD layout, read/write/compaction paths).\n- `docs-internal/engine/sqlite-vfs.md` — VFS parity rules.\n- `engine/packages/sqlite-storage/src/` — legacy code to lift from (after Stage 1 rename, this will be `sqlite-storage-legacy`).\n- `engine/packages/pegboard-outbound/src/lib.rs` — reference pattern for Standalone service registration.\n- `engine/packages/pegboard/src/actor_kv/` — reference for namespace-level metering pipeline (MetricKey, KV_BILLABLE_CHUNK).", + "userStories": [ + { + "id": "US-001", + "title": "Add NodeId type and accessor to rivet_pools::Pools", + "description": "As the compactor lease and metrics, I need a stable per-process NodeId so leases can identify holders and metrics can label by node.

Hot-path ops collapse to two RPCs (`get_pages`, `commit`) with no `open`/`close` lifecycle, no fence inputs on the wire, and pegboard exclusivity as the only writer fence. Compaction triggers go through UPS (queue-group balanced) and use a UDB-backed `/META/compactor_lease` to prevent concurrent compactions. META splits into four sub-keys (`/META/head`, `/META/compact`, `/META/quota`, `/META/compactor_lease`) so commit and compaction never conflict on the same key. Quota is an FDB atomic-add counter at `/META/quota`; the cap (10 GiB) is a Rust constant, enforced via an in-memory cache loaded lazily on the first UDB tx. Spec lives at `.agent/specs/sqlite-storage-stateless.md`. Read the spec first.\n\n===== KEY INVARIANTS =====\n\n- Actor-side (pegboard-envoy) is stateless. No `open`/`close`, no per-conn `active_actors` HashMap, no presence tracking. Only per-conn state is a perf-only `scc::HashMap>` populated lazily by SQLite request handlers.\n- The crate exports a single per-actor type `ActorDb`. No `Pump` struct, no process-wide registry, no per-conn wrapper inside sqlite-storage.\n- Pegboard exclusivity is the only writer fence in release. Defensive in-tx checks for 'two writers detected' are `#[cfg(debug_assertions)]` only.\n- No takeover work in release. Pegboard's reassignment transaction does not touch sqlite-storage. Lazy first-commit META init seeds `/META/head` if absent. Debug builds run `takeover::reconcile` for invariant verification only (no cleanup).\n- META sub-keys: `/META/head` (commit-owned, vbare), `/META/compact` (compaction-owned, vbare), `/META/quota` (raw i64 LE atomic counter), `/META/compactor_lease` (vbare).\n- `/META/quota` is fixed-width i64 LE. FDB atomic-add is exact integer addition (no drift). Mismatch = bug at the call site.\n- Quota cap is a Rust constant: `SQLITE_MAX_STORAGE_BYTES = 10 * 1024 * 1024 * 1024` in `pump::quota`. No `/META/static` key; remove it entirely.\n- Compactor service is `ServiceKind::Standalone` registered in `engine/packages/engine/src/run_config.rs`, same pattern as `pegboard_outbound`. UPS queue-group `\"compactor\"` balances work across pods.\n- Lease lifecycle uses a local timer + cancellation token + periodic renewal task. No `/META/compactor_lease` reads inside compaction work transactions.\n- PIDX deletes use FDB `COMPARE_AND_CLEAR` to resolve commit-vs-compaction races without taking conflict ranges.\n- Per-actor compaction trigger throttle (500ms window, 30s safety net). First trigger fires immediately; subsequent ones in the window are dropped. This is throttle, not debounce.\n- Breaking changes are unconditionally acceptable. The system has not shipped to production. Wire shape, on-disk key layout, and `DBHead`/META schema are all free to change.\n\n===== ARCHITECTURAL CONTEXT =====\n\n- Single crate `engine/packages/sqlite-storage/` with two top-level modules (`pump/` and `compactor/`) plus a top-level `takeover.rs`.\n- `pump/` is the hot path. Used by pegboard-envoy. Exports `ActorDb`.\n- `compactor/` is the background service. Registered as a Standalone service.\n- `takeover.rs` is debug-only invariant verification. Not compiled in release.\n- The legacy crate gets renamed to `sqlite-storage-legacy` for reference during the rewrite, then deleted in the final stage.\n- All tests live under `tests/` (no inline `#[cfg(test)] mod tests` in `src/`).\n- Metrics use `lazy_static!` global statics. All metrics include a `node_id` label sourced from `pools.node_id()` (see US-001).\n\n===== RUN COMMANDS =====\n\nFrom repo root:\n\n- Compile-check a crate: `cargo check -p ` (preferred for verification).\n- Build a crate: `cargo build -p `.\n- Run all tests for a crate: `cargo test -p `.\n- Run a single test file: `cargo test -p sqlite-storage --test `.\n- Run a single test: `cargo test -p -- --nocapture`.\n- Never run `cargo fmt` or `./scripts/cargo/fix.sh` — the team formats at merge time.\n\n===== READ BEFORE STARTING =====\n\n- `.agent/specs/sqlite-storage-stateless.md` — the full spec this PRD implements.\n- `engine/CLAUDE.md` — VBARE migration rules, Epoxy keys, SQLite storage tests, Pegboard Envoy notes.\n- `CLAUDE.md` at repo root — layer constraints, fail-by-default rules, async lock rules, error handling.\n- `docs-internal/engine/sqlite-storage.md` — current SQLite storage crash course (META/PIDX/DELTA/SHARD layout, read/write/compaction paths).\n- `docs-internal/engine/sqlite-vfs.md` — VFS parity rules.\n- `engine/packages/sqlite-storage/src/` — legacy code to lift from (after Stage 1 rename, this will be `sqlite-storage-legacy`).\n- `engine/packages/pegboard-outbound/src/lib.rs` — reference pattern for Standalone service registration.\n- `engine/packages/pegboard/src/actor_kv/` — reference for namespace-level metering pipeline

Read that first. The new design here adds two operator-facing features: point-in-time recovery (PITR) and actor forking. Both are layered on top of the stateless storage + standalone compactor described in the base spec. + +> **PITR is logical recovery, not infrastructure DR.** This system protects against logical errors (bad commit, accidental delete, corrupt application state) by allowing rollback within a configurable retention window. It is NOT a backup against FoundationDB cluster loss, multi-region failure, or hardware corruption. If FDB itself loses data, all checkpoints are lost too. External backups + object-store tiering (Open Questions) are the eventual DR story. + +## Goals + +1. **Point-in-time recovery.** Restore an actor's SQLite state to any committed `txid` within a configurable retention window. Granularity = single commit (within retention) or single checkpoint (older). +2. **Forking.** Create a new actor whose initial SQLite state is a copy of an existing actor's state at a specified `txid`. +3. **Bounded storage.** Retention overhead is predictable and configurable, both per-actor and per-namespace. +4. **No hot-path overhead.** `get_pages` and `commit` latency must not change. PITR/fork machinery lives in the compactor and admin pipelines, not on the actor path. The single exception is the restore-in-progress commit guard (see "Concurrency model"). +5. **Off by default, opt-in per namespace.** Default `retention_ms = 0` and `allow_pitr = false`. Consumers who do not need PITR pay zero storage overhead. +6. **User-atomic admin ops.** From the user's perspective, `actor.restore(...)` is a single API call. Suspend/resume orchestration is internal. +7. **Survives pod failures.** Long-running ops (restore, fork) are idempotent and resumable across compactor pod failures via persisted operation state. + +## Non-goals + +- Cross-actor consistent snapshot bundles (multi-actor coordinated point-in-time). Each PITR/fork is per-actor. +- Read-only "time travel" — mounting an actor's SQLite at a prior txid for queries without modifying the head. v1 supports only destructive restore + fork-into-new-actor; read-only mount is future work. +- Continuous external backup to object stores. Out of scope (see Open Questions). +- Cross-region replication. Out of scope. +- Automatic incident-driven rollback. Operator-triggered only. +- Changing the `commit` / `get_pages` wire shape (the base-spec hot path). PITR/fork operations live on a *separate* admin protocol. + +## How the stateless base spec breaks PITR + +The base-spec compactor folds DELTAs into SHARDs and **deletes the DELTA blobs**. Once compacted, per-commit history is gone — there's no way to reconstruct page state at any prior `txid`. + +To support PITR + fork without abandoning the stateless design, this spec adds two on-disk constructs and one hot-path guard: + +1. **Checkpoints** — frozen full-state snapshots at specific `txid`s, in their own keyspace. Created periodically by the compactor. +2. **Retention-aware DELTA cleanup** — DELTAs are only deleted by compaction once they are both (a) covered by a newer checkpoint and (b) older than the retention window. Within the window, DELTAs are preserved untouched, giving per-commit restore granularity. +3. **Commit guard against in-flight restore** — commits check whether a restore is in progress and bail. This is the only hot-path overhead introduced (one optional cached read per first commit). + +PITR restore re-applies preserved DELTAs against the most recent checkpoint ≤ target. Fork copies the same checkpoint + replays DELTAs into a fresh actor's keyspace. + +## Data structures + +New per-actor key prefixes (under existing `[0x02][actor_id]`): + +``` +/CHECKPOINT/{ckp_txid: u64 BE}/META — vbare blob: { taken_at_ms, head_txid, db_size_pages, byte_count, refcount: u32, pinned_reason: optional } +/CHECKPOINT/{ckp_txid: u64 BE}/SHARD/{shard_id: u32 BE} — frozen SHARD blob (full copy) +/CHECKPOINT/{ckp_txid: u64 BE}/PIDX/delta/{pgno: u32 BE} — frozen PIDX entry (only if PIDX still pointed to a DELTA at checkpoint time) +/META/retention — vbare blob: RetentionConfig +/META/checkpoints — vbare blob: ordered list of { ckp_txid, taken_at_ms, byte_count, refcount } +/DELTA/{txid: u64 BE}/META — vbare blob: { taken_at_ms, byte_count, refcount: u32 } +/META/restore_in_progress — vbare blob: RestoreMarker (absent when no restore active) +/META/fork_in_progress — vbare blob: ForkMarker (absent when no fork active; on the dst actor's prefix) +/META/admin_op/{operation_id: Uuid} — vbare blob: AdminOpRecord (lifecycle + progress for an in-flight or recently-completed op; TTL-cleaned) +/META/storage_used_live — atomic i64 LE counter (live data only) +/META/storage_used_pitr — atomic i64 LE counter (PITR overhead: checkpoints + retained DELTAs) +``` + +`/META/quota` from the base spec **splits** into `/META/storage_used_live` and `/META/storage_used_pitr`. Total bytes still equals `live + pitr`. The split is required so commits can enforce only the live cap (predictable user-visible quota) while PITR overhead is governed by a separate per-namespace budget. Migration: on first read after the split, sum existing `/META/quota` into `/META/storage_used_live` and zero `/META/storage_used_pitr`. + +`/DELTA/{T}/META` adds a `refcount` field beyond the original spec's `taken_at_ms` + `byte_count`. The refcount pins individual DELTAs while a fork is replaying them (fixes correctness issue C3 from review). + +`RetentionConfig` (vbare): + +```rust +pub struct RetentionConfig { + pub retention_ms: u64, // 0 = PITR disabled; default 0 + pub checkpoint_interval_ms: u64, // default 3_600_000 (1h) + pub max_checkpoints: u32, // default 25 (24h retention + 1 safety) +} +``` + +`/META/checkpoints` stays under the 16 KiB FDB single-value chunk threshold at default retention. Refcount is mirrored here (also stored authoritative on `/CHECKPOINT/{T}/META.refcount`) so a single read of `/META/checkpoints` powers `DescribeRetention` without scanning every checkpoint. Updated atomically with refcount changes (see "Refcount semantics" below). + +`AdminOpRecord` (vbare): + +```rust +pub struct AdminOpRecord { + pub operation_id: Uuid, + pub op_kind: OpKind, // Restore | Fork | Other + pub actor_id: String, // src for fork; subject for restore + pub created_at_ms: i64, + pub last_progress_at_ms: i64, + pub status: OpStatus, // Pending | InProgress | Completed | Failed | Orphaned + pub holder_id: Option, // pod currently working it; None when terminal + pub progress: Option, + pub result: Option, + pub audit: AuditFields, // caller_id, request_origin_ts_ms, namespace_id +} + +pub struct OpProgress { + pub step: String, // human-readable + pub bytes_done: u64, + pub bytes_total: u64, + pub started_at_ms: i64, + pub eta_ms: Option, + pub current_tx_index: u32, + pub total_tx_count: u32, +} +``` + +`AdminOpRecord` lives in UDB (NOT in-memory on a pod) so an HTTP poll endpoint always has the source of truth, even after the working pod dies.

Plan phase (snapshot reads): + - Read /META/head — capture ckp_txid_candidate = head.head_txid (use this exact value for the rest of the pass). + - Read /META/compact, /META/checkpoints, /META/retention. + - Identify deltas to fold; classify each as fold-only or fold-and-may-delete (retention math). +2.

Old-checkpoint cleanup: any /CHECKPOINT/{T} where T < (now - retention_ms_in_txid_terms) AND refcount == 0 AND T is not the latest checkpoint → delete (multi-tx); atomic_add /META/storage_used_pitr (-bytes). +``` + +**Quota check at checkpoint creation** (review #8): if `(storage_used_live + storage_used_pitr + estimated_checkpoint_bytes) > namespace.pitr_max_bytes_per_actor`, skip the checkpoint and increment `sqlite_checkpoint_skipped_quota_total{actor_namespace}`. Operator gets an alert; fix is to lower retention or raise the namespace budget. + +`max_concurrent_checkpoints` is a separate `CompactorConfig` knob (default 16, lower than `max_concurrent_workers = 64`) since checkpoints are 10-100× heavier than regular compactions. + +### Retention-aware DELTA cleanup (replaces base spec's "delete folded DELTAs") + +``` +DELTA T may be deleted iff: + T <= latest_checkpoint.txid + AND + DELTA[T].taken_at_ms < (now - retention_ms) + AND + DELTA[T].refcount == 0 +``` + +The refcount clause (review C3) ensures an in-flight fork that needs to replay a delta keeps it alive even past retention. + +If `retention_ms == 0` the time clause collapses to "always", behavior matches the base spec exactly. + +The compactor reads `/DELTA/{T}/META` during plan phase to evaluate retention. + +### Refcount semantics (review C3, M2, M4) + +Two separate refcounts: +- **Checkpoint refcount** at `/CHECKPOINT/{T}/META.refcount` and mirrored in `/META/checkpoints[i].refcount`. +- **Delta refcount** at `/DELTA/{T}/META.refcount`. + +Both are pinned by an in-flight fork. They are released by the fork-completion path (success or aborted-with-cleanup). + +Mandatory tx sequencing for refcount mutations: + +1. Refcount increment is in its own committed tx, before the lease that protected the read of the candidate ckp/deltas is released. Sequence: `Tx A: atomic_add(+1) on every pinned key; commit. Tx B: release lease; commit.` +2. Refcount decrement is in its own committed tx after work using the pinned object completes. +3. Decrement-on-abort uses the same separate-tx pattern; never combined with read-then-conditional-decrement in one tx (atomic-add visibility within a tx is undefined in this codebase's UDB). + +Auto-recovery for leaked refcounts (review #3): the compactor scans `/CHECKPOINT/*/META.refcount` and `/DELTA/*/META.refcount` once per pass. Any refcount > 0 with no live `/META/admin_op/{id}` referencing the actor is a leak. After `lease_ttl_ms × 10` of staying leaked, the compactor logs `sqlite_checkpoint_refcount_leak_total` AND **resets to 0**. The first-class admin op `ClearRefcount(actor_id, ckp_txid)` (or `(actor_id, delta_txid)`) is exposed for manual operator recovery. + +## Restore procedure + +User-facing flow (atomic): + +``` +api-public POST /actors/{id}/sqlite/restore { target: RestoreTarget, mode: RestoreMode } → +{ operation_id: Uuid, status: "pending" } +``` + +User polls `GET /actors/{id}/sqlite/operations/{operation_id}` (or subscribes via SSE).

Allocates `operation_id`; writes `AdminOpRecord{ status: Pending }` at `/META/admin_op/{id}`. +3. Calls `pegboard.suspend(actor_id, reason="sqlite_restore", op_id)` and waits for confirmation.

Cached: if the WS conn observes `/META/restore_in_progress` is absent on any commit, it sets `ActorDb.restore_observed_clear = AtomicBool(true)` and skips the read on subsequent commits within the same WS conn lifetime. Restore happens at most once per actor lifetime under normal operation, so the cache saves nearly all reads. + +When restore enters Tx 0 it writes `/META/restore_in_progress`. A concurrent commit reading the marker now sees it and bails.
