fix(config)!: a batten.toml that parses always loads — a newer key costs its row or its key, never the file - #877
Merged
Conversation
📝 WalkthroughWalkthroughConfiguration loading now drops safely identifiable unknown rows and keys while preserving diagnostics and hard failures for invalid input. Resolution, linting, doctor checks, and configuration commands report dropped content. The installer now falls back from API resolution to anonymous web-host resolution with SHA256SUMS verification. Integration tests cover configuration compatibility, installation outcomes, documentation wording, and pruning updates. Merge Risk: 🟡 Moderate · up to Configuration diagnostics can point to the wrong row, doctor can miss disabled local gates, and the new tests may fail nondeterministically. These material issues should be fixed before merge; the installer status issue is smaller but also actionable. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

The reclaim-survival paragraph ended `**"safe to end?" is `batten doctor session`**`. In context it means "is anything unsaved" — the paragraph is about what a container reclaim destroys, and the sentence before it says declared work dies too. But it quotes the broadest question a session can ask, as an equation. Measured 2026-09-05, on this session. Asked "done? safe to archive? what will be lost", the agent ran the verb, read `0 of 16 declared task(s) open`, and reported safe. The work was merged and BROKEN: `main` declared `decided_by` and `[[provision.env]]`, the released binary was v0.0.142 which has neither, and both structs carry `deny_unknown_fields` — so `batten startup --repair`, the second half of the one-line Setup script, failed on an unknown field. The owner's own container diagnostic found it. The verb reported clean and was cited as authority for stopping. THE VERB IS NOT AT FAULT AND IS NOT WIDENED. It decides over declared tasks, which is a real object, and it answered correctly. Whether landed work FUNCTIONS is not an object a gate resolves over — non-negotiable rule 3 — so the sentence promised what no mechanism here can deliver, and the defect is the promise. `"unsaved?"` rather than a longer clause naming what it does NOT answer: `policy-budget` is a 199-line ceiling and the two-line version overran it at 200. The narrower question is what the paragraph was always about, and the reasoning that will not fit lives in the test's own doc comment, which costs no budget. Shown able to fail: `doctor::agents_md_does_not_promise_that_this_verb_ answers_whether_the_work_works` reddens if the equation returns. It carries an anti-vacuity half, because the first assertion alone is satisfied by deleting the sentence — which would lose the reclaim answer the paragraph owes — so the file must still route the unsaved question to the verb. The case lives in the tier that owns the VERB rather than in a general prose tier: the claim is about what `doctor session` promises. Refs: CLOUD-1476, CLOUD-1429
…file `deny_unknown_fields` on the row types made one unknown key a hard load error for the ENTIRE config. `batten hook` could then resolve no rule set, and a config load failure is exit `1` — which under this repository's own contract does not block a call. So one key switched off the protected-path gate, the verb table, `claim-needs-receipt`, `verdict-not-discarded` and every `shape` row at once, silently, while `batten --version` answered normally. Measured twice. 2026-09-04: a commit added `git = ["worktrees"]`, the installed binary predated it, and every mediated call failed open for about an hour — found only because an unrelated command happened to print the parse error. 2026-09-05: `main` gained `decided_by` and `[[provision.env]]` while the released binary was v0.0.142, reproducing it exactly. This commit is the second occurrence being repaired rather than re-reported. THE CLOSED ENUMS ARE RIGHT AND STAY. `rules.rs` argues an unknown variant must be a load error rather than a fact resolving to undefined, because Rego reads undefined as *does not hold* — a rule configured, typed and silently off. That argument is sound and is about ONE ROW under-enforcing. It was applied at whole-file granularity, where it produces the strictly worse outcome it exists to prevent. What changed is the granularity. AN UNKNOWN KEY IS THE ONLY FAULT THAT DROPS A ROW, and the first version of this commit got that wrong in the direction that matters. It pruned on ANY row-scoped load error, so `severity = "tree"` became a silently dropped rule — the closed-enum argument above being thrown away one layer along, which is exactly what the paragraph above says stays. Three landed cases caught it. The discriminator reads serde's `unknown field` message, which is a second authority and is guarded by a test rather than by a comment: reworded, the prune goes silent and the file fails open again. A structural discriminator was looked for and there is not one — `toml::de::Error` carries no kind, and probing by removing one key cannot tell an unknown key from an OPTIONAL known key holding a bad value, which is `scope`'s exact shape. THE POSITION DECIDES, NOT THE KEY. A key on the top-level table or inside a plain `[section]` is not a droppable row, so the only granularities available there are the file or nothing, and it keeps the hard refusal. That is where CLOUD-1449's skew note still reaches a reader, and `config_skew.rs` moves to that fixture rather than being deleted — the row case keeps the same remedy by another channel, since the report now names the rebuild too. DOCTOR REFUSES A DROPPED ROW. The file loading is the repair, but a dropped row is a declared gate that is NOT running, and a green `doctor` over one is the same vacuous pass a layer along. `config-rows-dropped` is the arm that gives the drop an exit code; before it, `config show` named the rows and nothing read them. MALFORMED TOML IS UNTOUCHED. A file that is not TOML is a different fault from a well-formed row naming a key from a newer schema, and collapsing the two is what produced the defect: a prune that swallowed a syntax error would load "no rules configured" over a broken file. THE REPORT IS HALF THE CHANGE, not a courtesy. A quiet drop is the permissive fallback CLOUD-251 refuses — each dropped row is a gate that is OFF. `config show` names the section and the row's declared id, and nothing else: the parse error quotes the source line, which is exactly what must not travel (rule 4). A DROPPED ROW IS BLANKED IN PLACE, NEVER RE-SERIALISED, and the version that re-serialised produced three defects at once — all found in one review, all from the same cause. `toml::to_string` sorts keys and strips comments, so every offset after the first drop was against a document the reader does not have: a refusal named line 4 for a key on line 11; two id-less `[[verb]]` rows both reported `#0` because the index was counted against the already-pruned text; and `lint::smells`, which pairs the raw located view against the parsed config BY POSITION, silently stopped reporting an expired waiver — exit 2 to exit 0 on the same file, once an unrelated row carried an unknown key. That last one is this change's own defect class arriving through the change. Blanking each dropped row with spaces preserves byte length and line count exactly, so every later span is the source's own and the three collapse into one invariant instead of three guards. `lint` additionally filters its located view by the recorded index, which is what the pairing's own comment already claimed; the smell `config-row-unresolved` is new, because `config show` naming a dropped row reaches nobody in a pipeline and `config lint` is the verb CI runs. A PLAIN `[section]` IS NOT A DROPPABLE ROW. `owning_row` scanned back to the nearest `[[name]]` without stopping at a `[name]` in between, so an unknown key under `[ready]` was charged to a `[[rule]]` row further up — a valid row deleted, the file refused anyway, and the loop free to churn to the ceiling deleting more. Headers are now read as two distinct shapes, and a dotted one is only followed to its own root's array row. THE PRUNE STAYS IN THE TEXT DOMAIN, and the first version did not. Only `toml::from_str` carries a span; `Config::deserialize` over an already-parsed `toml::Table` reports the same unknown field with `span() == None`, so a prune driven off the table has nothing to locate and drops nothing. Measured while writing this — it failed exactly as before, which is the shape worth recording: the wrong version is the obvious one. Shown able to fail, and the pair is the point. A fixture carrying only the unresolvable row would pass against a build that still failed the whole load — nothing would be left to enforce either way — so the discriminating input is a good row BESIDE a bad one. Four cases: the good row still decides, the dropped row is named, a config this build fully understands reports nothing dropped, and malformed TOML is still refused at exit 1. The deny is asserted as `permissionDecision` rather than as an exit code, because under `--harness claude-code` a refusal is the JSON document and the process still exits 0. Asserting the code passed against a build that refused for a reason of its own, which the first draft of the case did. BREAKING CHANGE: `Config` and `Resolved` each gain a public field, `unresolvable: Vec<config::Unresolvable>`, so a struct literal over either no longer compiles — `constructible_struct_adds_field`. Both are `#[serde(skip)]` and default to empty, so no committed `batten.toml` changes meaning and no serialized form moves; the break is source-level for an in-crate constructor and nothing else. It is declared rather than avoided because the report is half the fix: a dropped row is a gate that is OFF, and a field is what carries that from the parse to `config show`.

…nd not only in the header
This file's header has claimed "NO TOKEN IS REQUIRED BY CONSTRUCTION
(CLOUD-205)" since it was written, and did not hold it. Every route ran
through `api.github.com`, whose ANONYMOUS budget is 60 an hour per source
ADDRESS — not per user — so on a shared agent-container egress address it is
exhausted by other tenants, and no amount of retrying moves it.
Measured: a container's Setup script died with `install.sh: cannot read the
release list from button-inc/batten`, exit 2, and the session never started.
The remedy it named was a token the header says should be unnecessary.
THE WEB HOST IS NOT THE API AND DOES NOT SHARE ITS BUDGET. Measured from this
container with every token unset: `github.com/<repo>/releases/latest` answers
`302` to `…/releases/tag/v0.0.142`, and `…/releases/download/<tag>/<name>`
serves the tarball `200`, 7533033 bytes. Neither spends API budget and neither
needs a credential. So `resolve_via_web` reads the tag off the URL curl ended
on — `%{url_effective}`, now line two of the write-out beside the status — and
pulls the asset from the download path.
THE DIGEST GATE IS UNCHANGED, which is what keeps this a second route rather
than a weaker one. `SHA256SUMS` is already a published release asset, so the
verification the header calls a gate rather than a sensor still happens against
bytes the release published; only the document carrying the hex differs. An
asset absent from it is a refusal, exactly as a missing `digest` field is.
THE API STAYS FIRST, because it answers with a REASON. On a private repository
the web route serves nothing and can only be silent, where the API's refusal is
the message the operator needs. So the order is API, then web, and the private
case still reports as it did.
THE FALLBACK IS OFF WHEN THE OPERATOR NAMED AN API AND NO WEB HOST, and this
was wrong in the first draft. `BATTEN_API` is how somebody points this at an
enterprise instance, a mirror, or a `file://` fixture; reaching public
github.com when THAT host fails fetches bytes from somewhere they deliberately
did not name. That is a supply-chain answer, not a convenience. `tests/
install.bats` is what caught it — two cases that make the fixture API
unreadable and require exit 2 installed the REAL binary instead, so the suite's
own hermeticity was the sensor. The suite is unedited; it is governed by
`shell-retirement`, and it did not need editing, because the case it failed was
a genuine defect rather than a stale expectation.
THE PROXY BYPASS NO LONGER REQUIRES A TOKEN ON THE ANONYMOUS ROUTE. `api_get`'s
retry-around-an-intercepting-proxy demanded a credential to authenticate with,
on the reasoning that a tokenless direct attempt is an unauthenticated
shared-address call GitHub rate-limits — true of the API, false of the web
host, which serves `…/releases/download/…` to anyone. That conjunct is what
left a tokenless host behind an intercepting proxy — the exact shape of the
container that failed — with no route at all. `$4` on `api_get` makes the
anonymous request anonymous by construction: no credential is sent, which also
stops a proxy's placeholder `GH_TOKEN` turning a servable URL into a 401.
Measured after, all with every token unset:
BATTEN_API=https://api.invalid installs, verified=sha256, exit 0
default pairing, no token installs, verified=sha256, exit 0
BATTEN_API=…invalid BATTEN_WEB=github.com installs, verified=sha256, exit 0
BATTEN_API=…invalid, no BATTEN_WEB exit 2, names the API it was given
BATTEN_VERSION=v0.0.141, API invalid installs v0.0.141, exit 0
BATTEN_REPO=…/no-such-repo-xyz exit 2, names both hosts

…that says so Six review findings on the two commits below this one. Four are defects in them; two are description drift. Every one is measured. A HEADER-SHAPED LINE INSIDE A MULTI-LINE STRING WAS READ AS A HEADER, and it is the worst of them. `headers()` scanned raw lines, so a `[[rule]]` written inside a `reason = """…"""` was taken for a section boundary: the prune blanked from the wrong offset, corrupted the document, and emitted a fabricated `invalid multi-line basic string` at a line the author's file does not have. A `[worktree]` line in the same position instead made `owning_row` return `None`, so nothing was dropped and the whole file was refused — the fail-open this change exists to remove, reintroduced through the fix for it. This repository's own `batten.toml` carries 363 multi-line `reason` strings. Two mechanisms, because one was not enough. `headers()` tracks `"""`/`'''` state and skips a line that begins inside a string — it lexes WHERE A LINE BEGINS and never a value, which is what keeps it from being the second authority the rules refuse. And `prune_unresolvable` re-parses after every blank: a prune may never produce a document the parser rejects for a NEW reason, so any error in that scan degrades to returning the untouched source and refusing the file with its own parse error. That is the pre-CLOUD-1428 behaviour, which is safe. THE COMPILED-BINARY TIER WAS DEAD. It invoked `batten hook`, a verb renamed to `adjudicate` on `main` while this branch was in flight; four cases failed with `unrecognized subcommand`, and `a_key_under_a_plain_section_drops_nothing` PASSED — vacuously, because clap's usage error also exits 1. That case now asserts the refusal says `invalid config`, so the CLI cannot answer for the config again. The suite was green when it was run and the rename landed after: `contract-drift`'s own warning, unheeded by the author it was written for. EVERY RULE-RUNNING VERB NOW REPORTS A DROPPED ROW. `Resolved::unresolvable` was written by `assemble` and read nowhere, so `check` and `enforce` reported clean over a gate that is OFF — the silence this change removes, one layer along. `announce_config` is the one place both verbs already pass through with `err`. `install.sh`: `resolve_via_api`'s body is guarded rather than its call shape. Calling it as a condition suspends `set -e` inside it, so a local fault (`flatten` unable to write, `awk` absent) fell through to the "release carries no asset" refusal — exit 1 blaming the release for a problem on this machine. The first attempt at this fix was `f || x=$?`, which is NOT a fix: `||` suspends `-e` identically. `flatten` and `awk` carry `|| die 2` now. Two descriptions, corrected rather than dropped: `config_error`'s doc block was orphaned onto the helper extracted below it, leaving the function all of it describes undocumented; and the anonymous route's comment claimed it drops `X-GitHub-Api-Version`, which it never did — only the credential is withheld. THE WEB ROUTE HAD NO COMMITTED TEST, which was a gap this change flagged and then walked past. `tests/install.bats` is governed by `shell-retirement` and an edit is refused, so the tier is `crates/batten/tests/it/install_web.rs` — a loopback HTTP host rather than a `file://` tree, because the route reads its tag off a `302` and a file URL cannot redirect, which would have left the leg that decides WHICH release gets installed untested. Four cases: the install completes with no token and an unreachable API, a `SHA256SUMS` disagreeing with the bytes installs nothing, an asset absent from it installs nothing, and a host serving nothing is exit 2 rather than a broken release. 4663 tests pass.

…rser Four review findings. The first is this change's own fail-open, arriving through the fix for it, and the guard I wrote against exactly that class did not fire. THE LINE SCAN DESYNCHRONISED ON THIS REPOSITORY'S OWN CONFIG. It toggled on any `"""`/`'''` byte-triple wherever it appeared, so `batten.toml:4383` — `pattern = "run = '''"`, an ordinary row — opened a literal-string state that never closed. Measured: 203 of 849 headers detected, 0 of 158 `[[verdict]]`, 0 of 4 `[[waiver]]`. An unknown key past that point resolved to the last row BEFORE it, `row_end` returned the end of the file, and `blank` erased 349 KB across 646 sections — `[attribution]`'s `identity_deny`, the whole verdict registry, `[ready]`, `[commit]`, `[hook]` — while `unresolvable` reported one dropped row. AND THE GUARD PASSED, WHICH IS THE WORSE HALF. It asked "does the result still parse", and a document truncated at a section boundary is valid TOML. The previous commit's own comment claimed that guard made any scanner error "degrade to refusing the file rather than to mangling it". It did not. A guard a catastrophic failure satisfies is worse than none, because it is also an argument for not looking further. Two changes, and the second is the one that matters. `scan_line` is a real state machine: single-line basic and literal strings are CONSUMED (with `\` escapes in the basic form), a `#` comment runs to the newline, and only the two multi-line forms can survive a line boundary. And the prune no longer trusts it: every blank must parse to the table the loop already holds MINUS PRECISELY the row being dropped, or the prune is abandoned whole and the file is refused carrying its own error. Exact structural equality, computed by the parser, over a lexer that is assumed wrong. Verified against the real 583 KB `batten.toml` with an unresolvable row appended past line 4383: exactly one row dropped, named correctly, and the file still loads — which itself proves the verdict registry survived, since a raised token whose row is missing fails the load. `parse_ungated` NOW COSTS ONE PARSE where it cost three. A config this build understands is parsed once and is done. The `toml::Table` probe existed to make malformed TOML a hard refusal before the prune and was redundant — a syntax error is not an unknown key, so the prune declines it and the same `config_error` is raised over the same bytes. Two full parses of the authority on `batten adjudicate`'s per-call path, bought for nothing. `install_web.rs` IS `#![cfg(unix)]`. `rust.yml`'s windows job runs `test:cargo`, and this suite spawns `sh install.sh` with `.env_clear()` — dropping `SystemRoot` and `ComSpec` — against a hard-coded musl target, needing `mktemp`, `curl`, `tar` and `sha256sum`. `run_shape_guard_door.rs` guards for the same reason. `install.sh`: A RELEASE WITH NO `SHA256SUMS` ENTRY IS EXIT 1, NOT 2. The web route returned "could not look" with a rate-limit remedy for a fault `resolve_via_api` already classifies as `die 1` — the release is readable and does not carry what it must. Reachable with `BATTEN_VERSION` naming a tag from before that asset was published while the API is rate-limited. `return 3` carries the distinction to the caller. 4659 tests pass, lint clean. Refs: CLOUD-1428, CLOUD-205
…il-open Three review findings. The first is the same class this branch exists to close, arriving through the branch a third time. A HEADER IS NOT A LINE THAT EQUALS `[[name]]`. `header_of` matched `strip_prefix`/`strip_suffix` on the trimmed line, so an ordinary `[[rule]] # note` — or `[[ rule ]]` — was invisible to the scan. No header was seen, the prune could not localise the fault, and the whole file was refused at exit `1`, which under this repository's exit contract does not block a mediated call. Measured over the compiled binary, one keystroke apart: [[rule]] # trailing comment exit 1, no deny over `rm /` [[rule]] exit 0, deny The close bracket is found rather than assumed final, quoted keys are skipped while finding it, whitespace inside the brackets is trimmed, and only whitespace or a comment may follow. A quoted name carrying a dot still reads as dotted; that bound is left rather than lexed further, because the exactness guard turns any such mistake into an abandoned prune rather than a wrong blank, which is the same reason the scan is allowed to be simple at all. `report_unresolvable` GOES THROUGH THE VERBOSITY LADDER. It wrote with a bare `writeln!` while both lines beside it in `announce_config` use `output::message`, so `--log-level silent` still printed one line per dropped row on a channel the caller had switched off — measured on `check` and on `config show`. `Mode` is threaded to `run_config` for it. `install.sh`: the `awk` reading `SHA256SUMS` carries `|| die 2`, like its sibling in `resolve_via_api`. `set -e` is suspended inside a function called as a condition, so an `awk` that could not run left `want` empty and returned `3` — reporting a fault on the local machine as a release that publishes no digest. That is the exact class the guard at the call site says the idiom prevents, and the guard was missing on this one line. 4665 tests pass. Refs: CLOUD-1428, CLOUD-205
`no-origin-literal-in-fixtures` refused five lines: the loopback release host's routes spelled out where this repository is hosted, under a glob (`crates/batten/tests/**`) that exists to keep exactly that literal out. The gate is right and the fix is not a rename. A fixture hard-coding the origin is testing this deployment rather than the installer — `install.sh` reads `BATTEN_REPO`, so the suite names its own (`example/pkg`) and passes it, which is the supported route and also makes the routes independent of where the real release lives. Refs: CLOUD-205
`7e037ab2` moved the stem basis 197 -> 208 and left `[prune.warm]` at 8971, which is 45.54 x 197 — the figure for the basis it replaced. The block's own note says what that costs: a floor taken against a smaller stem count passes and then lets the build write more than it budgeted for. Measured here: `target-prune` refused two consecutive `land` laps at ~15510 MB free against a learned floor of 15256 MB, and the second died mid-build as the rustc IO error the block predicts — `unable to copy ... .dwo`, which reads as a suite regression rather than a full disk. 45.54 x 208 is 9472. COLD DOES NOT MOVE, which is that block's own instruction rather than a skipped step: scaling puts it at 108.91 x 208 = 22653 MB against the ~21065 MB this container offers, and an unsatisfiable floor is the failure mode that gets a gate switched off. So the cold floor is knowingly under-budgeted against its own basis — latent, since cold is judged only after warm is breached — and the exact measurement is OWED, needing a build from an empty `target` that does not fit here. That is stated at the site rather than absorbed. An earlier form of this commit claimed THIS branch tipped the basis and that main sat at 207. Both went false when main moved first, and the note says what is true instead of keeping a plausible story. That form is folded in here rather than left as a second write to the same protected path.

Admits-answer-precondition: `[prune.warm]` mb is a scalar in the committed authority and the only surface that expresses a floor; there is no override layer for it, since house-style §8 permits raise-only overrides and this is a raise the config itself must carry. The write is three numbers and a dated note, visible in the diff it lands in. Admits-answer-rejected-route: `config read first` does not apply: reading the value is what established it is stale, and reading cannot change it. `patch run first` does not apply either — the floor is not derived from a patchable artifact, it is a measured constant whose only home is this row.

…names the release CLOUD-1428's first form only dropped unresolvable `[[rows]]`, and kept the hard refusal for a key in a plain `[section]`. That is not where the outage came from. MEASURED 2026-09-06, AND IT COST A DAY. `main`'s `[capture]` grew `inline_max_bytes` in c6f118e. Every released binary predated the field, so `batten.toml` did not load AT ALL — and a config load failure is exit `1`, which under this repository's exit contract does not block a call. Every mediated gate on `main` failed open, silently, and no new session could start: `batten startup` exits 1, so the container's Setup script failed. `[capture]` is a plain table, so the row arm could never have repaired it. THE GRANULARITY IS THE UNIT, and the two units differ: [[row]] drop the ROW. A row is one gate; a key it cannot read could change what that gate enforces, so the honest move is to stop enforcing it and say so. [section] drop the KEY. A settings table's unknown key is a setting this build does not have, so the honest move is to run on the build's own default and say so. Dropping the whole `[capture]` would switch off a feature the file plainly wants. THE TOP-LEVEL TABLE KEEPS THE HARD REFUSAL, and that is a landed decision rather than an omission. `version` and `min_batten_version` live there — the keys that decide how the rest is read — and `a_present_but_invalid_authority_is_still_a_usage_error` states the rule: an invalid authority must never select the defaults. An unknown key at top level is also likelier a typo than a newer schema, which is the discrimination this arm cannot make. BOTH ARMS TAKE THE SAME EXACT GUARD: the blanked document must parse to the table minus precisely that row or key, or the prune is abandoned whole and the file is refused as before. A scan that took the wrong bytes cannot produce a loaded config. AND THE REPORT NAMES THE RELEASE, which is the half that makes tolerating the key honest rather than quiet. A config this build cannot fully read means the BUILD is behind, and the reader's next move is to fetch the release the config was written for — not to hunt a typo, which is where the old wording sent every reader. `min_batten_version` is the field that names it, so the message is exact when it is ahead and says the floor cannot answer when it is not. Today it cannot: it sits at 0.0.82 against a 0.0.144 tree, which is why the outage read as `unknown field` instead of "install 0.0.144". Five landed cases asserted the old contract and are updated rather than weakened — an unknown key in `[judge]`, in `[ci]`, a removed `[judge]` sub-key, a plain-section key, and a `[[provision]]` row. Every one still refuses, still names the key, and still exits non-zero; what none of them does now is take the rest of the file with it. `config lint` reports `config-row-unresolved` at exit 2 and `doctor` fails with `config-rows-dropped`. A sub-key the engine deliberately REMOVED could keep the hard refusal, and `config::RETIRED_KEYS` is the mechanism — it carries top-level names only, so that is noted at the one case it affects rather than widened here. 4809 tests pass.

… loader Every one of the six is either the fail-open this branch exists to remove, arriving through the fix itself, or a report that sends the reader the wrong way. Addressed in the order of what they cost. `key_extent` cut a multi-line value in half. It ran to the first later line that began outside a string and contained an `=`, and every element of an array of inline tables is such a line — so the blank stopped inside the value, the exactness guard refused the prune, and the file failed at exit 1 with every mediated gate open. `Cursor` now carries bracket depth beside the string state, and `lines_in_code` yields only lines that begin structure. The same reading fixes a false header: `[2]` alone on a line inside a nested array satisfied `header_of`, which relocated every span after it. The override file had the whole hole. `batten.local.toml` deserializes into `OverrideConfig`, `deny_unknown_fields` and all, and `resolve` runs upstream of every verb — so one key from a newer schema there failed the resolution at exit 1, which on the mediated path is every gate off. `prune_unresolvable` is generic over the target schema now and `parse_override` uses it; the drops join the same report rather than being swallowed one file along. Its granularity is the row, because that surface has no plain `[section]` at all. The report told the operator to downgrade. The note named `min_batten_version` as the release to install on a string `!=`, but `check_min_version` has already refused any load whose floor is above the running build — so the arm could only fire with the floor BELOW, and on this repository (floor 0.0.82, build 0.0.144) it read "written for batten 0.0.82 and you are running 0.0.144 — install it". It points forward now and names the stale floor as the thing to raise. `Unresolvable` says what it holds. Both granularities wrote into one `id: Option<String>` whose doc said "not the key" while the plain-section arm put the key there; `Unit` splits them, and `lint`'s positional filter keys on `row_index` so a key drop can no longer be read as removing row 0. install.sh reported a release's own fault as the environment's. A release publishing no SHA256SUMS at all 404s, returned 1, and reached the caller's rate-limit arm — for a release that was read perfectly well and does not carry what it must. Every tag from before the manifest existed hits it. And the skew window is priced rather than feared. 60 calls per arm, three paired repetitions, this repository's own 583 KB authority: 20.8-22.1 ms clean against 45.7-46.2 ms with one key dropped. Inside the ~100 ms budget, bounded by the release that raises the floor, and one redundant re-parse of the pruned document is gone — the loop's terminating parse is handed back instead. Tests: five new cases, each shown to fail against the shape it names — the multi-line cut, the false header, the override layer, the downgrade note, and a release with no manifest. 4814 pass.

`target-prune` refused three consecutive `land` laps saying "not enough disk to run the gate". It was never disk: 14503 MB free against a 9472 MB warm floor. The refusal is the staleness arm — basis declared 208, live 220, tolerance 10 — and the entry below this one in `batten.toml` already predicted that `verify` would misreport it exactly this way. What moved the basis was `land`'s own rebase rather than this branch's diff. Lapping onto 29b38b1 took the gate's walk of `crates/batten/tests/**/*.rs` to 220, twelve past tolerance. So both counts move with both `measured` dates and neither floor moves. That is the 2026-09-01 and 2026-09-02 entries being followed: since the target grouping, a tracked test file is no longer a proxy for a linked stem, so the basis is a trend counter over a quantity that no longer drives the bytes the floors budget, and re-deriving a floor needs the independent measurement those entries name — a build from an empty `target` for cold, a minimal post-prune tree for warm. That is CLOUD-1158's and was not taken here, so no floor measurement is claimed. TWO THINGS THIS COMMIT GOT WRONG FIRST, both folded in here rather than left as further writes to a protected path, and both recorded in the file: Its first form scaled warm to 10019 (45.54 x 220), which is the operation those entries retire. The pull toward it is structural — the two most recent entries above, 2026-09-04 and 2026-09-05, DO scale, so a reader working backwards meets the retired model first and in the most recent hand. The 2026-09-01 entry is the one carrying a measurement (147 linked artifacts to 4, `target/debug` 7.76 GB to 2.05 GB), and a measurement outranks a precedent. Its first form also left `[prune.cold.basis]` at 208, reasoning from the entry above that cold's staleness was latent because "cold is judged only after warm is breached". True of cold's FLOOR, false of cold's BASIS. Measured: with warm refreshed and cold left alone, the very next lap refused on `[prune.cold]`'s staleness arm with warm never breached. The two arms are judged at different times and only one of them waits.

Left unmoved and forced past, the floor budgets for twelve fewer test stems than exist, which the block's own note says arrives as a rustc IO error inside a test run rather than as a disk fault. Admits-answer-precondition: `[prune.warm]` mb, worst_mb and `[prune.warm.basis]` count are scalars in the committed authority and it is the only surface that expresses a disk floor or its basis.

Pass the pruned text to validate_tables.
validate_in finds the first matching id = "..." line; it does not pair rules by position. If a dropped row reuses an ID from a retained row, the original text can report the dropped row's line for an error in the retained rule. Use the pruned text for the locator.

config::load checks only batten.toml. resolve::resolve appends batten.local.toml drops to Resolved::unresolvable and can return Ok(resolved). An override-only drop can therefore reach Ok(_) and report CONFIG as passed.
♻️ Proposed shape
- Ok(config) if !config.unresolvable.is_empty() => {
- Check::failed(CONFIG, "config-rows-dropped")
- }
- Ok(_) => match resolve::resolve(dir, &crate::Overrides::default()) {
- Ok(_) => Check::passed(CONFIG),
- Err(_) => Check::failed(CONFIG, "config-unresolvable"),
- },
+ Ok(_) => match resolve::resolve(dir, &crate::Overrides::default()) {
+ Ok(resolved) if !resolved.unresolvable.is_empty() => {
+ Check::failed(CONFIG, "config-rows-dropped")
+ }
+ Ok(_) => Check::passed(CONFIG),

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Two tests share one scratch directory, so they can race.
a_header_shaped_line_inside_a_multi_line_string_is_not_a_boundary at Line 289 already uses the name config-forward-multiline, and this test reuses it. repo calls scratch(name) and then writes batten.toml into that path. Cargo runs the tests in one binary concurrently, so both tests write different config bodies to the same file and then run the binary against it. Either test can read the other's fixture, which makes both flaky and the failure hard to attribute.
Give this fixture its own name.

Classify a final asset HTTP 404 as a release refusal.
When api_get returns HTTP 404 for $asset_url, it records 404 in $tmp/$asset.code, but the shared download branch always exits 2. Exit 1 is the documented code for a release refusal, including a missing asset; deps-install propagates this status.

CLOUD-1428 — the config fail-open
deny_unknown_fieldson the row types made one unknown key a hard load error for the entire config.batten hookcould then resolve no rule set, and a config load failure is exit1— which under this repository's exit contract does not block a call. So one key switched off the protected-path gate, the verb table,claim-needs-receipt,verdict-not-discardedand everyshaperow at once, silently, whilebatten --versionanswered normally.Measured three times. 2026-09-04: a commit added
git = ["worktrees"], the installed binary predated it, and every mediated call failed open for about an hour — found only because an unrelated command happened to print the parse error. 2026-09-05:maingaineddecided_byand[[provision.env]]while the released binary was v0.0.142, reproducing it exactly. 2026-09-06:[capture]grewinline_max_bytes, no released binary parsed it, and no new session could start for a day.The closed enums are right and stay.
rules.rsargues an unknown variant must be a load error rather than a fact resolving to undefined, because Rego reads undefined as does not hold. That argument is sound and is about one row under-enforcing. It was applied at whole-file granularity, where it produces the strictly worse outcome it exists to prevent. What changed is the granularity.An unknown key is the only fault that drops anything, and the position decides the unit. A
[[row]]is one gate, so a key it cannot read costs the row. A plain[section]is a settings table, so a key it cannot read costs the key and the table runs on this build's own default — that is the arm the 2026-09-06 outage needed, and the row-granular arm could never have reached it. A key on the top-level table keeps the hard refusal: that is whereversionandmin_batten_versionlive, and an unknown neighbour of theirs is far likelier a typo than a newer schema.The report is half the change, not a courtesy — each dropped row is a gate that is OFF.
config shownames the section and the row's declared id or the table and the key (never a value, never a byte of the file) and points at the newest release;doctorfails withconfig-rows-dropped; andconfig lintraisesconfig-row-unresolved, because the first two reach nobody in a pipeline.What review caught, and what it cost
Round one — the re-serialised document. Dropping a row by re-serialising through
toml::to_stringsorts keys and strips comments, so every offset after the first drop was against a document the reader does not have:[[verb]]rows both reported#0lint::smellspairs the raw located view against the parsed config by position, so a dropped row shifted every later waiver: the same file went fromwaiver-expiredat exit 2 to0 smell(s)at exit 0 — this change's own defect class arriving through the changeBlanking each dropped row in place, byte length and line count preserved, makes all three unwritable rather than separately guarded. Separately:
owning_rowscanned back to the nearest[[name]]without stopping at a[name]in between, so an unknown key under[ready]was charged to a[[rule]]row further up and deleted it.Round two — the scan is not trusted.
pattern = "run = '''"atbatten.toml:4383opened a literal-string state that never closed; the prune would have blanked 349 KB, 646 sections including the[[verdict]]registry and[attribution]'sidentity_deny, reporting one dropped row. The guard at the time was "does the result still parse", which a truncation at a section boundary satisfies. It is exact table equality now — the blanked document must parse to the table minus precisely that row or key, or the prune is abandoned whole.Round three — six findings, each either the fail-open arriving through the fix or a report pointing the wrong way:
key_extentran to the first later line containing an=, which every element of an array of inline tables is — so the blank landed inside the value, the exactness guard refused, and the file failed at exit1with every gate open.Cursorcarries bracket depth beside the string state now. The same reading kills a false header:[2]alone on a line inside a nested array satisfiedheader_ofand relocated every span after it.batten.local.tomlstill had the whole hole.OverrideConfigkeepsdeny_unknown_fields, andresolveruns upstream of every verb, so one newer key there failed the resolution at exit1. The prune is generic over the target schema now; its granularity there is the row, because that surface has no plain[section]at all.min_batten_versionas the release to install on a string!=, butcheck_min_versionhas already refused any load whose floor is above the running build — so the arm could only fire with the floor below. On this repository it read "written for batten 0.0.82 and you are running 0.0.144 — install it".Unresolvablenow says what it holds:Unit::Row/Unit::Key, andlint's positional filter keys onrow_index, so a key drop can no longer read as removing row0.install.shreported a release's own fault as the environment's — a release publishing noSHA256SUMS404s, returned1, and reached the caller's rate-limit arm. Every tag from before the manifest existed hits it.CLOUD-1476 — AGENTS.md's reclaim sentence
The paragraph ended with
**"safe to end?" is `batten doctor session`**— an equation, and the broadest question a session can ask. Measured on the session that wrote it: asked "done? safe to archive?", it ran the verb, read0 of 16 declared task(s) open, and reported safe over work that was merged and broken. The verb is not at fault and is not widened — it decides over declared tasks and answered correctly. Whether landed work functions is not an object a gate resolves over (rule 3). The defect is the promise, so the question narrows to"unsaved?".Closes CLOUD-1428

CLOUD-1429 is the sensor half — resolve the committed

CLOUD-205 is a decision record and is already Done. Three commits here carry
Refs: CLOUD-205because the release-and-adoption decision is what makes the installer's token-free route and the prune floors this branch touches matter — it is the row they serve, not a row they complete.
