+# Context Pack: worker-applied-keys-dedup
+
+## Run Metadata
+
+| Field | Value |
+| ----- | ----- |
+| Run ID | `feat-prime-time-worker-applied-keys-dedup--impl` |
+| Branch | `feat/prime-time/worker-applied-keys-dedup` |
+| Current phase | `implement` |
+| Archetype | `ARCHETYPE-3 - Runtime / Behavior` |
+| Scope overlays | `SCOPE-service` |
+
+## Current State
+
+Implementation is complete for worker consumer-side applied-keys dedup. The branch carries the core
+message/port contract, key resolver, KV store, dispatcher gates, trigger producer propagation,
+composition wiring, tests, docs, and gate evidence.
+
+## Completed
+
+- Read harness/doctrine/tooling/PR instructions and the approved slice plan artifacts.
+- Confirmed branch `feat/prime-time/worker-applied-keys-dedup` tracks
+  `origin/feat/prime-time/worker-applied-keys-dedup`.
+- Created implementation run artifacts.
+- Implemented all approved contracts and tests for this slice.
+- Ran scoped static gates, targeted runtime tests, JSR audit, doc lint, and publish dry-run.
+
+## In Progress
+
+- Final docs/evidence commit and PR completion comment.
+
+## Next Steps
+
+1. Push final docs/evidence commit.
+2. Comment PR #79 ready for IMPL-EVAL.
+
+## Key Decisions
+
+| Decision | Source | Notes |
+| -------- | ------ | ----- |
+| Worker idempotency is required | `plan.md` | Production must not silently fall back to no-op/in-memory. |
+| Store uses shared `getKv()` | `plan.md` | Same durable KV handle as worker runtime state. |
+| Queue remains read-only | `research.md` | Consumer-side applied-key dedup is the defect site. |
+
+## Files Changed
+
+| Path | Status | Notes |
+| ---- | ------ | ----- |
+| `.llm/tmp/run/feat-prime-time-worker-applied-keys-dedup--impl/*` | new | Harness implementation artifacts. |
+| `packages/plugin-workers-core/src/ports/worker-idempotency-port.ts` | new | Storage-agnostic worker idempotency port. |
+| `packages/plugin-workers-core/src/runtime/worker-idempotency.ts` | new | Key resolver and hash fallback. |
+| `plugins/workers/worker/worker-idempotency-store.ts` | new | KV-backed applied-keys store. |
+| `plugins/workers/worker/job-dispatcher.ts` | changed | Claim/skip/mark/release gate for job and task effects. |
+| `plugins/triggers/src/runtime/trigger-runtime-processor.ts` | changed | Stamps idempotency key on `JobMessage`. |
+
+## Gates
+
+| Gate family | Current status | Evidence |
+| ----------- | -------------- | -------- |
+| Static | PASS | Scoped check/lint/fmt green for workers-core, workers, triggers. |
+| Fitness | PASS_WITH_EXISTING_ARCH_DEBT | JSR audit/doc lint/publish green; repo-wide `arch:check` fails on pre-existing unrelated debt. |
+| Runtime | PASS | Combined targeted run passed 35 tests. |
+| Consumer | PASS | workers-core, workers plugin, and triggers tests passed. |
+
+## Open Questions
+
+- None.
+
+## Drift and Debt
+
+- Drift: minor commit-order drift, composition wiring folded into consumer commit to preserve a
+  compiling branch after each push.
+- Debt: no new debt accepted.

+# Drift Log: worker-applied-keys-dedup
+
+Drift is append-only. Record facts that diverge from the plan, RFC, doctrine, or current-state
+documentation.
+
+## 2026-06-20 — Initialized
+
+- **What:** Implementation artifacts initialized from the PLAN-EVAL-passed brief.
+- **Source:** `.llm/tmp/run/feat-framework-prime-time--supervisor/slices/worker-applied-keys-dedup/implement-brief.md`
+- **Expected:** Implementation starts from approved plan artifacts.
+- **Actual:** No drift.
+- **Severity:** minor
+- **Action:** accept
+- **Evidence:** This run directory.
+
+## 2026-06-20 — Composition Wiring Folded Into Consumer Commit
+
+- **What:** Composition wiring is committed with the consumer gate instead of as a later standalone
+  commit slice.
+- **Source:** `plugins/workers/worker/worker-options.ts` makes `WorkerOptions.idempotency`
+  required.
+- **Expected:** Plan listed consumer gate before composition wiring.
+- **Actual:** Pushing consumer gate alone would leave in-repo `new Worker(...)` call sites
+  non-compiling until a later commit.
+- **Severity:** minor
+- **Action:** accept
+- **Evidence:** `plugins/workers/bin/runtime.ts`, `plugins/workers/services/src/service-runtime.ts`,
+  and `plugins/workers/services/src/routers/router-context.ts` are included with the consumer gate
+  commit to keep each pushed branch state type-checkable.

+## Contracts verified
+
+- `runtime-types.ts`: `idempotencyKey?: string` on both `JobMessage` and `TaskMessage`.
+- `worker-idempotency-port.ts`: `WorkerIdempotencyPort` + `WorkerIdempotencyInput` + `WorkerIdempotencyClaim` + `WorkerIdempotencySource` (matches plan spec).
+- `ports/mod.ts` re-export + `public/mod.ts` re-export via `public-schema.ts` named exports.
+- `worker-idempotency-store.ts`: concrete `KvWorkerIdempotencyStore` over `@netscript/kv` (getKv-shared).
+- `worker-options.ts`: `WorkerDispatchContext.idempotency` required; `WorkerOptions.idempotency` required.
+- `trigger-runtime-processor_test.ts`: producer stamps `idempotencyKey` onto `JobMessage` body.
+- `router-context.ts`: `WorkersServiceRuntime` exposes `idempotency: KvWorkerIdempotencyStore`.
+
+## Test plan vs delivery
+
+- Unit resolver precedence (caller > message-id > payload-hash): ✓ `worker-idempotency_test.ts` (3 tests).
+- Unit store (first-claim, duplicate, release, markApplied, TTL, non-durable-backend throw): ✓ `worker-idempotency-store_test.ts` (5 tests).
+- Integration dispatcher redelivery + failure-path + task gate: ✓ `job-dispatcher_test.ts` (3 tests).
+- Producer propagation: ✓ `trigger-runtime-processor_test.ts` (stamps idempotencyKey onto JobMessage).
+- publish:dry-run surface: ✓ passes.
+
+## Production bar checks
+
+- **Durable persistence (NOT in-memory):** KV-backed, shared `getKv()` handle, TTL-bounded (active `expireIn`, applied `expireIn`). ✓
+- **Idempotency under retry:** claim → markApplied / release flow; TTL releases crashed claims; no permanent wedge. ✓
+- **No in-memory-only set:** confirmed — port in core, KV impl in plugin; constructor throws if backend cannot guarantee durability. ✓
+- **Observability:** span event `worker.job.idempotent_skip` / `worker.task.idempotent_skip` + dedup metric attribute. ✓
+- **Structured already-applied (skip, not failure):** confirmed in dispatcher and test output. ✓
+- **Graceful shutdown:** TTL bounds guarantee no dangling active claims. ✓
+
+## Lock hygiene
+
+`deno.lock` not modified during the run. No stray files generated.
+
+## Slice-specific note (durable + idempotent under retry)
+
+Verified: `KvWorkerIdempotencyStore` persists to KV (`['workers','idempotency','active'|'applied', key]`), uses atomic when available with sequential-has+set fallback, and rejects non-durable backends. The retry path is exercised by `KvWorkerIdempotencyStore release allows a failed delivery to retry` and `processWorkerJob releases a failed claim so redelivery can re-run`.
+
+## Gaps
+
+None.

+### Contracts Verified
+
+- ✓ `JobMessage.idempotencyKey?: string` and `TaskMessage.idempotencyKey?: string` (runtime-types.ts)
+- ✓ `WorkerIdempotencyPort` interface with `claim/markApplied/release` (worker-idempotency-port.ts)
+- ✓ `KvWorkerIdempotencyStore` using KV atomic operations with TTL (worker-idempotency-store.ts)
+- ✓ Dispatcher integration: claim before dispatch, release on failure, markApplied on success
+- ✓ Trigger producer propagates `idempotencyKey` to job messages
+- ✓ Service runtime injects store into Worker instances via composition root
+
+### Production Bar Assessment
+
+- **Durable persistence:** ✅ KV-backed store with atomic versionstamp checks and TTL expiry (no in-memory-only set)
+- **Idempotency guarantees:** ✅ claim/markApplied/release lifecycle prevents double-apply on redelivery
+- **Failure recovery:** ✅ `release()` on failure allows retry; TTL expiry prevents permanent wedging
+- **Observability:** ✅ Skip telemetry events, idempotent skip counters, claim source tracking
+- **Graceful degradation:** ✅ Store throws on initialization if KV unavailable (no silent fallback)
+
+### Slice-Specific Verification
+
+**Applied-keys durability and idempotency under retry:**
+
+- KV atomic operations with `versionstamp: null` ensure exactly-once claims
+- Active claims have 15-minute TTL; applied markers have 24-hour TTL
+- Failed dispatches call `release()` to remove active claim, enabling retry
+- Test `KvWorkerIdempotencyStore release allows a failed delivery to retry` validates this path
+- No in-memory-only Set or Map used for deduplication
+
+### Test Plan Coverage
+
+- ✓ Unit: key resolution precedence (caller > message-id > payload-hash)
+- ✓ Unit: store operations (claim, markApplied, release, TTL expiry, non-durable rejection)
+- ✓ Integration: dispatcher redelivery prevention (job and task paths)
+- ✓ Integration: failure release and retry
+- ✓ Integration: trigger producer key propagation
+
+### Gaps
+
+None identified.
+
+### Verdict Rationale
+
+All required gates pass with comprehensive test coverage. The implementation correctly achieves exactly-once-effective semantics for worker job execution through durable KV-backed idempotency keys. The slice meets the production bar for persistence, error handling, idempotency, observability, and graceful failure recovery. No in-memory-only deduplication mechanisms are present. The implementation fully satisfies the locked contracts specified in plan-meta.json.
