Walks the repo from root, skipping `IGNORE_DIRS`: `node_modules`, `dist`, `.git`, `.devflow`, `.claude`, `.release`, `tmp`, `tests`, `coverage` (`tests` and `coverage` are skipped so a `.mds` committed under either — a fixture or a coverage artifact, never a shipped host — can never be compiled into the real `dist/` tree; the skip is by directory **name**, so it holds under `DEVFLOW_MDS_ROOT` as well, and a fixture host planted at `/tests/` is likewise invisible. A `DEVFLOW_MDS_ROOT` env var lets negative-path tests redirect the whole walk to a throwaway temp root instead of the real repo). The recursion is bounded by `MAX_WALK_DEPTH` (12, counting the root as depth 0; the deepest `.mds` in the shipped tree sits at depth 4 and the deepest directory under `src/assets/` at depth 6). The bound **throws**, it does not truncate: a host skipped for being too deep would compile nothing while the build still printed its counts and exited 0, and no test could distinguish "not there" from "never looked" (PF-018). `readdirSync` tolerates `ENOENT`/`ENOTDIR` (an entry can vanish between the parent's readdir and the descent) and rethrows everything else -2. For each `.mds` file: reads the FIRST `---…---` frontmatter block with a scalar regex (`readFrontmatterKey`, not a YAML parse — the build must not gain a YAML dependency); if it declares a non-empty `output-dir:` key, treats it as a host, else a partial (skipped). `BUILD_KEYS` (`output-dir`, `output-name`) is the one list of keys the build consumes; it drives both the read here and the strip in step 5 (for command hosts), so a key the build reads can never leak into a shipped artifact. A build key that is present but **valueless** is a malformed host and hard-fails during discovery with an explicit message (`output-dir: is empty …`, `output-name: is empty …`) — `readFrontmatterKey` returns `''` (not null) for a bare key, so `?? basename` would not fire and a silent basename fallback would hide the authoring mistake.

Before any frontmatter is read, each walked path is checked against `deferredReferenceModuleSources()` (computed once, from the one owner in `mds-variants.ts`): a path the registry knows about but whose generation gate is shut this build is bucketed straight into `deferred` and skipped — it never becomes a `HostEntry` and is never counted as a partial. For every other file: reads the FIRST `---…---` frontmatter block with a scalar regex (`readFrontmatterKey`, not a YAML parse — the build must not gain a YAML dependency); if it declares a non-empty `output-dir:` key, treats it as a host, else a partial (skipped). `BUILD_KEYS` (`output-dir`, `output-name`) is the one list of keys the build consumes; it drives both the read here and the strip in step 5 (for command hosts), so a key the build reads can never leak into a shipped artifact.

Validates the declared `output-dir` via `resolveOutputDir(root, declared)` from `src/core/mds-variants.ts`: containment (`isContainedIn`) → backslash rejection (declarations are POSIX-spelled by contract; `path.posix.normalize` leaves `\` untouched, so `dist\commands` would pass the canonical check on win32) → canonical-spelling check (POSIX-normalized, no trailing slash — `dist/commands/`, `./dist/agents`, `dist/skills/../commands` all refused) → allowlist match. On success it returns `{ variant, abs }` — the resolved absolute directory plus the `HostVariant` (`'commands' | 'agents' | 'skill-refs'`) the matching allowlist entry declares, which is what selects the strip strategy in step 5. All four error kinds (`escapes-root`, `backslash-separator`, `non-canonical`, `not-allowlisted`) are rendered by an exhaustive `switch` with a `never` default in `build-mds.ts` and **thrown**, so `main()`'s aggregation reports every refusal and exits 1 once after the loop — no mid-loop `process.exit` leaving `dist/` half-updated -4. **Plans the destination(s) before writing anything** (`planHost`, in `scripts/build-mds.ts`). `planHost` dispatches on the `HostVariant` returned in step 3 through an exhaustive `switch` (`never` default) to one of two strategies, each returning the same `HostPlan` type — a discriminated union on `variant`: the one-file arm (`commands`/`agents`) carries a single `dest`; the fan-out arm (`skill-refs`) carries `outputs: readonly PlannedReference[]`, each entry pairing its `dest` with the `(module, op)` pair that fills it, so there is no parallel-array correspondence to maintain and no arm can read a field the other arm owns. `destsOf(plan)` gives every caller that needs the uniform 'every file this host claims' view — the plan pass's claims loop, the contested-destination filter, the prune's claimed set — one function regardless of which arm it is. `planSingleFile` (commands/agents): the emitted filename (source basename, or the optional `output-name:` key's value) is validated via `validateOutputName` — charset `^[a-z0-9][a-z0-9._-]{0,63}$`, refuses `..`/`.` segments and path separators. `planReferenceModule` (skill-refs): `output-name:` is **refused outright** (there is nothing for it to name — see Gotchas), the module's source path is looked up in `VARIANT_MODULES`, and `expandVariants([module])` turns its `ops` list into the flat `(module, op)` pair list this host will emit, each path re-validated segment-by-segment. Every host's destination(s) — read through `destsOf()` — are recorded in a `Map` across the WHOLE plan pass — a destination claimed by two or more hosts disqualifies **every** claimant (letting the first win would pick arbitrarily between two equally-declared intents), and the build errors naming all claimants while unrelated healthy hosts still compile +4. **Plans the destination(s) before writing anything** (`planHost`, in `scripts/build-mds.ts`). `planHost` dispatches on the `HostVariant` returned in step 3 through an exhaustive `switch` (`never` default) to one of two strategies, each returning the same `HostPlan` type — a discriminated union on `variant`: the one-file arm (`commands`/`agents`) carries a single `dest`; the fan-out arm (`skill-refs`) carries `outputs: readonly PlannedReference[]`, each entry pairing its `dest` with the `(module, op)` pair that fills it, so there is no parallel-array correspondence to maintain and no arm can read a field the other arm owns. `destsOf(plan)` gives every caller that needs the uniform 'every file this host claims' view — the plan pass's claims loop, the contested-destination filter, the prune's claimed set — one function regardless of which arm it is. `planSingleFile` (commands/agents): the emitted filename (source basename, or the optional `output-name:` key's value) is validated via `validateOutputName` — charset `^[a-z0-9][a-z0-9._-]{0,63}$`, refuses `..`/`.` segments and path separators. `planReferenceModule` (skill-refs): `output-name:` is **refused outright** (there is nothing for it to name — see Gotchas), the module's source path is looked up via `referenceModuleFor`, which resolves against `resolveVariantModules()` — the GATED registry, never the raw `VARIANT_MODULES` constant, so a gated-but-open module is found the same way an unconditional one is — and `expandVariants([mod])` turns its `ops` list into the flat `(module, op)` pair list this host will emit, each path re-validated segment-by-segment (`validateContractOutputName` in place of `validateOutputName` for a `'contract'`-kind module, since its op name carries a mandatory leading underscore). Every host's destination(s) — read through `destsOf()` — are recorded in a `Map` across the WHOLE plan pass — a destination claimed by two or more hosts disqualifies **every** claimant (letting the first win would pick arbitrarily between two equally-declared intents), and the build errors naming all claimants while unrelated healthy hosts still compile 5. Compiles each host via `@mdscript/mds` `compileFile()`, THEN strips frontmatter — dispatched by an exhaustive `switch` over the `HostVariant` returned in step 3 (`never` default), never by comparing the resolved path against a re-derived destination constant. `commands` → `stripBuildKeys` removes every `BUILD_KEYS` line from the single real frontmatter block (every other key survives byte-untouched — no YAML round-trip); `agents` → `stripGeneratorFrontmatter` removes the ENTIRE first frontmatter block, promoting the second block (the artifact's real frontmatter) into place — verified on both ends (PRE: a leading block must exist; POST: a second block must be what the slice exposes — a single-block host, the shape every hand-authored agent has, would otherwise ship headerless with the build reporting success, PF-061); `skill-refs` → `stripReferenceFrontmatter` also removes the one leading block but verifies the OPPOSITE postcondition — a second block must NOT follow it, because a skill reference ships as plain markdown with no frontmatter at all (an author copying the generator-host habit of two blocks would otherwise leak `output-dir:` into every emitted file as content). All three strips run AFTER `compileFile` — the compiler emits a byte-0 frontmatter block verbatim, so block 1 survives compilation unchanged and is safe to slice off afterward -6. For `skill-refs`, `materializeOutputs` then hands the stripped body to `splitVariantSections(body, entries)` (the same pure module) — `entries` is each planned output's own `{dest, op}` record (from the plan's `outputs`), so the function returns exactly one `VariantSection` per entry passed in, each carrying a `content` field alongside the caller's original fields; there is no separate lookup structure and no non-null assertion, because the destination travels WITH its content rather than beside it in a map. The splitter walks the body line by line for `` markers, drops any module-level preamble before the first marker (it belongs to no operation, so shipping it would duplicate it into every file), and returns `Result[], SectionSplitError>`. Bidirectional and load-bearing both ways: `unknown-section` (a marker names an op the registry doesn't) and `missing-section` (the registry names an op the body never marks) both refuse the build; `empty-section` is a third, independent refusal (GAP-44) for a marker whose body is blank — the other two checks cannot see it, because a marker with an empty body compiles cleanly and would otherwise ship a zero-byte reference with no build signal at all +6.

The splitter walks the body line by line for `` markers, drops any module-level preamble before the first marker (it belongs to no operation, so shipping it would duplicate it into every file — `_linear.mds`'s `## Known Unknowns` section, which documents two inherited-not-measured facts for a human reading the source, is exactly this: it sits above the first marker and is emitted nowhere), and returns `Result[], SectionSplitError>`. Bidirectional and load-bearing both ways: `unknown-section` (a marker names an op the registry doesn't) and `missing-section` (the registry names an op the body never marks) both refuse the build; `empty-section` is a third, independent refusal (GAP-44) for a marker whose body is blank — the other two checks cannot see it, because a marker with an empty body compiles cleanly and would otherwise ship a zero-byte reference with no build signal at all 7. Writes each output — `{basename}.md`, `{output-name}.md`, or `{subdir}/{op}.md` per pair — to the declared `output-dir` via a temp file (`{dest}.{pid}.tmp` — scoped to the writing process so two concurrent builds never share one staging path) + `renameSync` (per-file atomic; the `.tmp` is cleaned up on rename failure; concurrent readers, e.g. parallel vitest workers, never see a partial write — avoids PF-011, whose ENOENT-window shape is exactly what the temp-then-rename sequence closes) -8. Hard-fails on any compile error — no stale command ever ships. Prints `N partial(s) skipped (no output-dir:)` and `N host(s) to compile:` — both lines are parsed by `tests/build-mds-generator-hosts.test.ts` §6 (AC-1.8); do not reword them. There is **no separate "references emitted" line**: a reference module's fan-out is folded into the same `compiled: {source} → {dest}` line every host prints, rendered as `{outDir}/ (N file(s))` when a host emits more than one file, rather than as a distinct census line -9. **Prunes** (`main()`, only after step 8 finds zero errors): `pruneOrphanAgents` deletes every `.md` under `dist/agents/` that no host in this build emitted, one `pruned: {path} (no generator host)` line each; `pruneOrphanReferences` runs the SAME sweep (shared `pruneOrphans` helper, bounded by the shared `MAX_REFERENCE_SWEEP_DEPTH` constant — 8, owned by and imported from `src/core/reference-sweep.ts` rather than redeclared) recursively over `dist/skills/git/references/`, one `pruned: {path} (no reference module)` line each — recursion is not optional there, since the tree is nested `tracker/{provider}/{op}.md` and a flat sweep would leave every orphan exactly where it lives. A breach (`depth > MAX_REFERENCE_SWEEP_DEPTH`, the walked root counted as depth 0) is answered differently by the build's own `pruneOrphans`, which **throws** (a generated tree that deep is a build bug, and `dist/` is the build's own tree to fail), than by the installer's `sweepOrphanedReferences` in the same module, which instead **reports** the unswept subtree into its `failed` array (avoids PF-009 — one bad subtree does not abort the whole install); one constant, two call sites, two deliberately different failure postures for the same breach. Both directories are gitignored and outrank their `src/` counterparts in every consumer that resolves from them, so a file left behind installs in preference to the audited source on every `devflow init`. Scope is deliberate: **`dist/commands/` is never pruned** (it also receives `release.md`, copied verbatim from a hand-authored source that is not a host); non-`.md` entries are left alone in every pruned directory (a concurrent build's `{dest}.{pid}.tmp` staging file lives there); and a refused build prunes nothing. `AGENTS_OUTPUT_DIR` and `SKILL_REFS_OUTPUT_DIR` (both the allowlist table's own spellings) name the prune targets even when zero hosts of that kind are planned — the case where every file in the directory is an orphan, so the target cannot be derived from the plan +8. Hard-fails on any compile error — no stale command ever ships. Prints `N partial(s) skipped (no output-dir:)`, `N reference module(s) deferred (generation gated)` — naming each held-back source (`deferred: {source} (no registered provider needs it yet)`) — and `N host(s) to compile:`; all three lines are parsed by `tests/build-mds-generator-hosts.test.ts` §6 (AC-1.8) and the PF-064 non-vacuity arm in `tests/packaging.test.ts`; do not reword them. The deferred count is subtracted from the partial-count arithmetic EXPLICITLY (`totalCount - hosts.length - deferred.length`) rather than left to fall out of it, so a gated module can never silently move the partial count for a reason that is not a roster change. There is **no separate "references emitted" line**: a reference module's fan-out is folded into the same `compiled: {source} → {dest}` line every host prints, rendered as `{outDir}/ (N file(s))` when a host emits more than one file, rather than as a distinct census line +9. **Prunes** (`main()`, only after step 8 finds zero errors): `pruneOrphanAgents` deletes every `.md` under `dist/agents/` that no host in this build emitted, one `pruned: {path} (no generator host)` line each; `pruneOrphanReferences` runs the SAME sweep (shared `pruneOrphans` helper, bounded by the shared `MAX_REFERENCE_SWEEP_DEPTH` constant — 8, owned by and imported from `src/core/reference-sweep.ts` rather than redeclared) recursively over `dist/skills/git/references/`, one `pruned: {path} (no reference module)` line each — recursion is not optional there, since the tree is nested `tracker/{provider}/{op}.md` (plus the flat `tracker/_mcp.md`) and a flat sweep would leave every orphan exactly where it lives. A breach (`depth > MAX_REFERENCE_SWEEP_DEPTH`, the walked root counted as depth 0) is answered differently by the build's own `pruneOrphans`, which **throws** (a generated tree that deep is a build bug, and `dist/` is the build's own tree to fail), than by the installer's `sweepOrphanedReferences` in the same module, which instead **reports** the unswept subtree into its `failed` array (avoids PF-009 — one bad subtree does not abort the whole install); one constant, two call sites, two deliberately different failure postures for the same breach.

The dedicated describe `dist/skills/git/references orphan prune` in `tests/build-mds-generator-hosts.test.ts` covers the following cases: unclaimed files are pruned and reported; nested directories are pruned; claimed outputs survive; non-`.md` staging files survive; root-level planted files are pruned because the build prune sweeps the entire generated tree root-included (unlike the installer's prune, which narrows to `references/tracker/**` because the installed skill dir mixes generated and hand-authored sources); refused builds perform no prune operation; depth-8 descent succeeds; depth-9+ descent fails without pruning. -The 13/14/14 count rule is owned by the `dynamic-workflow-engine` KB — see there for which number counts what and why the two 14s are different sets.

File copy is the sole install mechanism. All asset source paths are resolved via named accessors in `src/core/assets.ts`, which are backed by `getPackageRoot()` in `src/core/paths.ts`. `installViaFileCopy` returns an `InstallReport` that `init.ts` uses to surface shadow, skip, orphan-sweep, and reference-overlay events in the post-install summary. -The shadow override system lets users place personal versions of skills or rules at well-known paths under `~/.devflow/`.

Manifest: `generatedReferenceManifest()` (also in `mds-variants.ts`) derives 34 relative paths from `expandVariants()` itself (never hand-listed) — 10 `tracker/github/{op}.md` files, 10 `tracker/jira/{op}.md` files, 10 `tracker/linear/{op}.md` files, the three cross-cutting documents (`decision-markers.md`/`learn-conventions.md`/`publication-gate.md`), and the tool-call contract `tracker/_mcp.md`; it throws if the registry fails to expand, rendering the FULL `VariantExpansionError` payload (not just its `kind`) since the payload names the offending module/op — a compile-time-constant programming error rather than an install-time degradation. - **Before the unit loop runs**, `requireGeneratedTree(sourceRoot, manifest)` stats the compiled references root ONCE and throws — naming `npm run build:mds` — only when that stat fails with `ENOENT` (the whole tree is absent, e.g. `npm run build:cli` alone was run). Any other stat failure (`EACCES`, a bad filesystem) falls through to the ordinary per-unit reporting path rather than aborting the whole install; this is a single check, not a per-unit one, precisely because the per-unit build loop has no isolation for a refusal this early — one unbuilt provider would otherwise abort every other unit. -- Isolation unit (`D-OVERLAY-FLAT-UNIT`): `OverlayUnit = OverlayUnitRef & { files }`, where `OverlayUnitRef` is a discriminated union — `{ kind: 'provider'; subdir }` (subdir spelled exactly as the registry declares it, e.g. `tracker/github`) or `{ kind: 'cross-cutting' }` (a discriminated union rather than a name string carrying a sentinel value, since a provider directory could in principle hold that same value). One `tracker/{provider}/` directory, OR the whole flat cross-cutting set as a single unit — never one unit per flat file, so three documents that are always generated and read together report one outcome, not three. `planOverlayUnits` groups the manifest by directory in deterministic order (flat set first, then providers sorted by path). -- Each unit is staged under a `.tmp` sibling at a **process-unique** path (`buildUnitStagingTree`; an orphan tmp from a crashed prior run is pre-cleaned first — PF-011): `tracker/{provider}.-.tmp` for a provider, `tracker/.cross-cutting.-.tmp` for the flat set — both placed under the `tracker/` subtree the prune converges, so a tree stranded by a crash is swept by the NEXT run's prune rather than needing its own recovery path.

One `tracker/{provider}/` directory, OR the whole flat set for one directory as a single unit — never one unit per flat file, so documents that are always generated and read together report one outcome, not several. `planOverlayUnits` groups the manifest by directory in deterministic order, sorted by directory part. +- Each unit is staged under a `.tmp` sibling at a **process-unique** path (`buildUnitStagingTree`; an orphan tmp from a crashed prior run is pre-cleaned first — PF-011): `tracker/{provider}.-.tmp` for a provider, `tracker/.cross-cutting.{dirSlug}.-.tmp` for a flat set, keyed by a slug of its own directory (`root` for the references root, `tracker` for the `tracker/`-rooted contract file) so two flat units in the same run — the references-root set and the `tracker/_mcp.md` contract — never share a staging path and cannot pre-clean each other's half-built tree — both placed under the `tracker/` subtree the prune converges, so a tree stranded by a crash is swept by the NEXT run's prune rather than needing its own recovery path. The pid keeps two concurrent `devflow init` runs from deleting each other's half-built staging tree (the first step of staging is `rm -rf` on the staging path); the timestamp keeps a REUSED pid from adopting a tree a still-earlier crashed run left behind. +- Promotion (`promoteUnitStagingTree`) dispatches on `unit.kind`: `promoteProviderUnit` displaces the installed directory to a `.old` sibling **before** the staging tree is renamed in (never `rm(target)` then `rename`), so a rename that fails partway calls `restoreDisplacedUnit(backup, target)` to put the `.old` copy back — itself a function returning a Result rather than a swallowed `.catch(() => undefined)`, because a failed restore is a materially worse outcome than a successful one and the report must say which happened. `promoteCrossCuttingUnit` promotes the flat set one `rename` per document into `underRoot(referencesTarget, unit.dir)` — no directory to swap, since a flat set's documents land beside entries the overlay must never replace or delete — a mid-flight failure here leaves it part new and part old. - A failure — build or promotion — is reported as `{ unit, state, error }` on `overlayFailures`, a shape that names the failing unit and the state it was left in. `state: OverlayFailureState` is a closed union naming exactly what is on disk: `installed-unchanged` (nothing touched), `not-installed` (first install, never had a copy, names the absent files), `partially-refreshed` (the flat set stopped mid-rename, names `refreshed`/`stale` file lists), or `restore-failed` (a provider's `.old` backup could not be put back, names the `recoveryPath` and the restore error). Per-item isolation still holds (PF-009; proven by a dedicated test: one unreadable file in a second provider's directory leaves that provider byte-unchanged while the other installs normally). Symlink source entries are skipped with a `warn()` call and never followed — `copyDirectory` follows symlinks and preserves source modes, which is exactly why the overlay does its own copying instead of reusing it. - The ONE throw path inside the per-unit build loop: a manifest entry absent from the generated tree throws `Generated skill reference not found for declared reference "{relPath}": {absolute}` with an `npm run build:mds` hint — a missing build artifact was never produced, which is a packaging failure, not an install-time degradation; every other build/promotion failure is reported via `overlayFailures`, never thrown (PF-009). (`requireGeneratedTree`'s whole-tree check above is the second, coarser throw path.) - Prune (`sweepOrphanedReferences`, `src/core/reference-sweep.ts`): converges `references/tracker/**` to the manifest, recursively, path-keyed, bounded at `MAX_REFERENCE_SWEEP_DEPTH = 8` (exported from `reference-sweep.ts`; every walker over this tree — this sweep, the build's own prune, the test harness's `walkFiles` — shares the one constant and answers a breach differently: this sweep reports it into `failed`, the build throws, `walkFiles` throws). Directory-prefix membership is checked against a `Set` built once per sweep (`directoryPrefixes`) rather than re-scanning the full manifest per entry. Scoped strictly to that `tracker/` subtree — hand-authored references living directly in `references/` (`github-api.md`, `violations.md`) are never touched. A shadow-injected stray file (e.g. `tracker/jira/comment.md`) is removed on the next install; a whole subdirectory with no manifest path descending into it is removed whole, not left empty. A missing/unreadable root is a no-op (PF-009) — the overlay creates the tree it converges, so nothing to prune yet is valid. `prunePreservingRecoveryCopies` wraps the call: when a `restore-failed` unit's `recoveryPath` sits under the prune root, the prune is **skipped for this run** (reported through `pruned.failed`, not silently) rather than deleting the one surviving copy of that unit's mechanics in the same run that named it as the way back. Removals otherwise fold into `InstallReport.sweptOrphans` via `recordSweep(report, 'reference', sweep: SweepResult)` — `SweptAssetKind` was widened to `'skill' | 'command' | 'agent' | 'reference'` for exactly this. - `chmodRecursive` normalises the WHOLE `references/` tree to `0644` (`D-OVERLAY-MODE-SCOPE`), not only this run's files — `copyDirectory` preserves source modes, and a reference is read-only instruction text regardless of how it got there; best-effort, a filesystem that ignores mode bits must not fail the install (PF-009). It is now bounded by the shared `MAX_REFERENCE_SWEEP_DEPTH` and reports a breach through the overlay's own `warn()` channel rather than throwing (the module's other caller, `composeScripts`, still swallows a breach silently — a three-level shipped-asset tree breaching an 8-level bound is a packaging shape no walk in this repo expects). This is the ONE step that reaches a file the overlay does not otherwise own, which is why the module's boundary is stated as "never REPLACE or DELETE" rather than "never touch" — ADR-024 corollary (b) (the settings.json ownership guard protects deletion, not overwrite) is what licenses normalising the mode of a hand-authored reference outside the manifest; it does not license replacing or deleting one. - `FileCopyOptions.warn?: (msg) => void` (defaults to a no-op) is the non-fatal-notice channel the overlay uses for skipped symlinks, mode-normalisation failures, and a `chmodRecursive` depth breach; `devflow init` passes its own logger, callers with no logger are unaffected. - Uninstall is unchanged by this addition: generated references live inside `~/.claude/skills/devflow:git/references/`, which `removeAllDevFlow` / `sweepDevflowNamespaces` remove wholesale as part of the skill directory — there is no separate reference-cleanup step on uninstall. -- Tests: `tests/installer/reference-overlay.test.ts` (mkdtemp roots only — PF-060; fixtures copied from the real generated references — PF-043; covers shadow-independence AC-2.4a, atomic isolation AC-2.4b with an unreadable-file probe that `ctx.skip()`s when the read cannot be revoked, loud failure on a missing manifest entry, shadow-injected + stale-provider prune AC-2.4c, symlink-skip, 0644 normalisation, the `formatOverlaySummary` render site, and failed-promotion restore) and `tests/packaging.test.ts` (Guard 6e pins all 13 generated references in the packed tarball via `generatedReferenceManifest()`). +- Tests: `tests/installer/reference-overlay.test.ts` (mkdtemp roots only — PF-060; fixtures copied from the real generated references — PF-043; covers shadow-independence AC-2.4a, atomic isolation AC-2.4b with an unreadable-file probe that `ctx.skip()`s when the read cannot be revoked, loud failure on a missing manifest entry, shadow-injected + stale-provider prune AC-2.4c, symlink-skip, 0644 normalisation, the `formatOverlaySummary` render site, and failed-promotion restore; `tracker/_mcp.md` is pinned as the THIRD manifest shape alongside a provider directory and the references-root flat set, with six dedicated failure-path rows that go red if `isProviderSubdir` reverts to the old any-non-empty-directory rule; the fixture provider is `probe-provider`, deliberately absent from the real manifest, so the stale-prune and isolation arms exercise a provider the overlay would actually orphan rather than one that later became real) and `tests/packaging.test.ts` (Guard 6e pins all 34 generated references in the packed tarball via `generatedReferenceManifest()`). ### InstallReport @@ -127,6 +127,8 @@ The legacy `features.knownFlags` field from old manifests is read by `readManife `ManifestData.features.proxy: boolean` tracks whether external model routing was enabled at the last install. `readManifest` self-heals absent fields to `false` (applies ADR-014 self-heal idiom).

Before this, only the terminator search was fence-aware — the start was a raw `indexOf('## Operation: X')`, which prefix-matched a sibling operation's own heading (`fetch-issue` matching inside `fetch-issues-batch.md`'s line-1 heading) and let a fenced `## Operation:` sample make `'sole'` mode throw "found in multiple files" for what was actually a quoted example, not a second authority. Sections end at the next UNFENCED column-0 `## ` line — a `## ` line inside a fenced code block (3+ backticks/tildes, closed by a later same-or-longer same-character marker run; an unclosed fence runs to end of text) is payload, not structure (PF-063). The boundary rule lives in the named collector `collectUnfencedH2(text)` (see below), shared by the extractor and by `tests/tracker/reference-structure.test.ts`'s structural guard, so neither can drift from the other (PF-018). Because the boundary became fence-aware (`4fdc541`), most former hand-rolled file-scoped workarounds in `git-agent.test.ts` retired in favor of normal extraction: the setup-task/fetch-issue/fetch-issues-batch sites and the learn-conventions arm (b) in `collectConventionsCommitPlacementViolations` now call `extractOpSectionFromCorpus` directly ('sole' for the first three; 'union' over `sinkCorpus` for learn-conventions, since it's a NEGATIVE check that must stay live after the body moves into a reference — narrowing a negative check to git.md alone would go blind the moment the text it must NOT contain moves out). The AC-0.3 `## Issues Batch ({n} issues)` header guard is now op-scoped via `extractOpSection(soleCorpus, 'fetch-issues-batch', 'sole')`, because that header lives inside the op's fenced Output template and a fenced heading no longer forces a boundary. Two sites remain intentionally scoped outside the extractor, for reasons unrelated to truncation: Guard 10 (AC-0.10 containment) reads each op's own section via `opSection = extractOpSection(soleCorpus, op, 'sole')` — see the Guard 10 follow-up section below for why it was rewritten — and the seam test's `collectMissingProducers` stays body-scoped because both of its known-bad probes mutate the `git.md` BODY under test, and a corpus-shaped signature would push the mutation into a fixture instead of the input under test. ### collectUnfencedH2 (fence-aware `## ` boundary, PF-063) @@ -67,7 +71,7 @@ All three throw with a build hint when the artifact is absent — `requireDistFi ### walkFiles -`walkFiles(dir, accept, maxDepth = MAX_REFERENCE_SWEEP_DEPTH)` — recursive `readdirSync(withFileTypes)`, deterministic (sorted) order.

A future extractor rewrite inherits this obligation unchanged, with the baseline tree being the re-capture commit rather than `b6928e5`. **Safety map for `git.md` / generated-reference editors.** Sections still sampled directly from `git.md` (D4 degradation contract, D11 scrub rules, `ensure-pr-ready`, `validate-branch`, `setup-task`, `fetch-issue`, `fetch-issues-batch`, `post-review-summary`, the retained D4/Output halves of `manage-debt` and `learn-conventions`, `check-ci-status`, `create-release`, `gather-release-evidence`, `fetch-review-threads`, `resolve-review-threads`, `post-resolution-summary`, `check-merge-readiness`, plus 3 lines in `code.md` and lines in `dynamic-build.mds`/`resolve.mds`) stay content-anchored and safe to edit above/below the sampled range; editing text INSIDE a sampled anchor or heading needs a fixture-only regen. Sections sampled from the six generated references are sampled from the BUILT file — a source edit under `src/assets/mds/tracker/` needs `npm run build` before the fixture check can even run, and a wording change inside a sampled anchor still needs the fixture-only regen. `manage-debt` and `learn-conventions` need BOTH halves checked (git.md retained half + generated-reference moved half) since each is one straddling operation split across two files. -**Sanctioned post-capture source fix procedure:** Source fix commit → `npm run build` → fixture-only re-capture commit (authorised `--unfreeze` where applicable).

The backend switch is flipped by overriding `_HAS_JQ` directly — the variable `json_field_file` itself reads — rather than by hiding `jq` on `PATH`, because PATH surgery to simulate a missing tool is platform-dependent (PF-045: the same probe can find the tool via a different directory on a different OS). +- **`tests/seams/tracker-claim-staleness.test.ts`** — the claim-file staleness bound (`~/.devflow/.tracker.processing`) has two deciders that never talk to each other at runtime: the shell hook's `TRACKER_PROCESSING_STALE_SECS` and the Tracker agent's own bold-literal-seconds statement in its Step 0.

Mechanically: scan bounded recent history (`--max-count=200`) for closing refs; a `KEY-N` grammar at **≥3 occurrences AND ≥60% share** corroborates that provider; refs of the github grammar with **zero** qualifying `KEY-N` refs resolve `github`. Name the deciding signal on the status line. + +**The mismatch guard, and why the uninstall classification depends on it:** frontmatter `provider:` ≠ the resolved provider → `TRACEABILITY: DEGRADED (tracker configuration mismatch)` and **NO tracker call**. This is the reader-side invariant covering every path init cannot see — uninstall then reinstall, a hand edit, a dotfile-repo sync — and it is why the file is preserved as user content instead of swept as an install artifact: **a stale file is safe to keep only because it can no longer be silently authoritative.** + +**`- **Tracker**:` lives in the PREAMBLE, not in any op's Output template.** The first draft added the line to `setup-task`'s `### Traceability` template and the frozen `github-status-lines.txt` caught it — one added line. The fixture was right on the merits, not merely inconvenient: §14.2 says the GitHub path emits **no tracker status line at all**, so an unconditional template line was a defect. The rendering rule is now a clause of the github-silence bullet: *under any other provider, add `- **Tracker**: {provider} ({winning source}) | DEGRADED ({reason})` beside `- **Conventions**:`, additive, exactly one rendering, `({n} unresolved)` on first use.* **Do not add a status line to any op's Output template.** + +**★ AC-3.1 ⇔ AC-3.11: the Output templates' `#` is a RENDERING, and the rule that says so lives here.** The templates read `- **Issue**: #{number}`, `- **Number**: #{number}` and `### Issue #{number}:`, and line 48 of the frozen `github-status-lines.txt` is the first of them — so AC-3.1 makes them **uneditable for the life of this phase** while AC-3.11 wants `- **Issue**: PROJ-123` under Jira. The two criteria meet on the same bytes. §14.1 is the arbiter: `#`-prefixing is a property of the **github rendering** of `ISSUE_REF`, not of the field. The resolution is therefore a RULE and not a template edit — one bullet in `## Tracker input contract`: *every rendered ref takes `## Reference Rendering`'s form, **never `#`-prefixed** — the Output templates' `#` is github's rendering, not a literal.* Zero template bytes, both criteria satisfied, and `tests/tracker/schema-scope.test.ts` claim 6 pins it with a companion arm asserting the three slots still carry the `#` (if they lost it the rule would be a rule about nothing, and the frozen fixture would already have broken). + +**The branch half of AC-3.11 is deliberately NOT in the preamble.** `{type}/{KEY}-{slug}` with the type exact-matched against `## Issue Types` is stated by each provider's own `setup-task` mechanics, and a second copy in the always-loaded file is what the byte budget refuses and GAP-37 forbids. It is pinned per provider instead, from the shared claim table in `tests/helpers.ts`. **When a rendering rule must be always-loaded and a shape rule need not be, the test is whether the always-loaded text would be WRONG without it** — the templates are wrong without the `#` rule and silent without the branch rule. + +**The per-repo `tracker` key** (`src/core/feature-config.ts`): + +```ts +export type TrackerConfigOverride = + | { kind: 'absent' } // NO override — corroborate + | { kind: 'valid'; provider: TrackerProvider } + | { kind: 'invalid'; raw: string }; // carries the raw value for the DEGRADED +export interface FeatureConfig { /* … */ tracker?: string } // the RAW string, verbatim +``` + +**`absent` ≠ `github`.** Absent *requests* ref-grammar corroboration; a chosen `github` short-circuits it. Never collapse them. The field is the **RAW** string and is carried through `coerceConfig` **verbatim**, because `updateFeature` is a read-modify-write over the whole config — a key it dropped would be a key `devflow knowledge --disable` **deletes**. Never consume the field directly; always `parseTrackerOverride`. Membership delegates to `parseTrackerId` (ONE authority). `BooleanFeature` needed `-?`: a mapped type over an optional property yields `K | undefined`, and any future optional field inherits the fix. + +### 7.

Its mirror arm ranges over nothing, so it carries its own known-bad probe. **3c added no row** — Linear's reasons are the same canonical rows, and `unsupported by linear` became admissible the moment the provider was registered, because the `{provider}` token set is derived from the registry. +- **★ Two placeholders are INSTANTIATED, and both token sets are derived.** §14.2 states a reason as a template (`unsupported by {provider}`) while §14.4 fixes the per-provider cell as the instantiated form (`unsupported by jira`); both spellings are correct and they are different strings. `reasonSpellings()` admits a template plus its instantiations, with `{provider}` tokens read from the module registry's provider rows and `{capability}` tokens read from the tool-call contract's own capability table. Both sets are therefore CLOSED — `unsupported by asana` and `no tracker tool for frobnicate` are still reported — and registering Linear admits its spelling with no registry edit. `{ref}` and `{p}` are deliberately NOT instantiated: their values are runtime data with no closed domain. +- **The reason collector collapses whitespace.** A reason is a one-line status string and the prose stating it is hard-wrapped; the contract's capability clause wraps mid-reason, so the raw capture was `"no\ntracker tool for {capability}"` — a string matching no registry entry and describing no defect. Normalising beats reflowing the source, which would pin where a sentence happens to break (PF-057). +- **`PRE_PHASE3_REASONS` (1)** — `tech-debt archive failed for #…`, emitted by `references/tracker/github/manage-debt.md` and appearing **nowhere** in §14.2's canonical table. Registered **with its provenance** rather than papered over, because the reverse arm is "no reason outside the registry" and changing a Phase-2 literal that `manage-debt`'s own guards pin is out of scope for a behaviour-neutral subtask. **Treat this row as canonical until the appendix gains it or the literal is retired** — it is a real §14.2 gap, not a mistake in the registry. + +Literals the preamble added, all in `TRACEABILITY: DEGRADED (…)` form: `unknown tracker provider` · `tracker configuration unreadable` · `tracker configuration mismatch` · `tracker not configured` · `ambiguous issue reference` · `tracker.md required fields incomplete — edit ~/.devflow/tracker.md`. (`tracker mechanics unavailable` and `tracker.md exceeds size bound` were already present and stay byte-identical as literals.)

The decisions those sentences carried are kept, in words: #325's neutralisation of the tracker ops' wording deleted a duplicated sentence, so the always-loaded file got SMALLER while gaining a provider; the alignment pass then funded its M2 rendering rule by deleting `backlink-shipped-issues`' restatement of the D4 rate-limit rung (M4); and the second alignment pass's issue-ref scoping landed wholly inside the preamble. **`BUDGET_GIT_MD_P3` was NOT raised for any of it** — a ceiling is re-derived downward or not at all, and nothing about these changes earns a lower one. + +**Re-measure before spending, and read the LINEAR row, not this one.** Figures in this section had already drifted by the time the alignment pass measured them, which is why every "measured"/"headroom" number in `byte-budget.test.ts` and `numeric-floors.json` is re-derived from the printed table rather than carried forward. And the binding constraint is no longer the `git.md` ceiling: it is the **Linear loaded-set row**, because that row contains `git.md`.

[DR-13(c)]'s `_resolution.md` escape was **measured and rejected**: moving text into a per-op-summed reference is **NET ZERO** on that gate. +- **★ `_mcp.md` is billed at 0 on the GitHub row and priced PER PROVIDER elsewhere — shipped in 3b.** `MCP_TERM = 0` on the GitHub-scoped row **by construction**, because no github op file names `_mcp.md`; the re-scoped AC-2.7 guard proves it and a byte-budget arm re-proves it beside the gate. Each MCP-backed provider therefore gets its OWN loaded-set row and its OWN new ceiling entry derived from the printed table, and **no existing ceiling was raised**: the GitHub row still measures 80,837 ≤ 80,944. See each `## Provider:` section's loaded-set table for the numbers and `budget-loaded-set-jira` / `budget-loaded-set-linear` for the entries. A named arm fails any registered MCP-backed provider that has no ceiling of its own — it is what made 3c's ceiling land in the commit that registered the provider rather than after it — and the two per-provider gates are generated from one `PRICED_PROVIDERS` table, so a fourth provider adds a row rather than a copied pair of `it`s. + +## Component Interactions + +**Selection flow.** `devflow init` (or `devflow tracker --set`) resolves a provider → `renameStaleTrackerConventions` moves a stale file aside → the manifest is written → `rearmTrackerInference` clears the counter → `applyTrackerSentinel` converges `.tracker.enabled`. Order matters: the rename reads the *prior* provider, so it must run before the write. + +**Inference flow.** SessionStart (`startup`/`clear`) → Section 3's five gates → counter incremented → `--- TRACKER SETUP ---` in `additionalContext` → the main model **silently** spawns `Agent(subagent_type="Tracker", model="sonnet", run_in_background: true, prompt: "… Provider: {token}. Devflow directory: {abs}. Project root: {abs}")` → the agent claims, probes, infers, writes `tracker.md` once, deletes the counter, deletes the claim. The next session's gate 0 sees `tracker.md` and exits at one `stat` forever after. + +**Read flow.** A Git agent spawn resolves `TRACKER_PROVIDER` **once** in the preamble (per-repo key → corroboration → manifest → github) → reads `tracker.md` if present (Read tool, absolute path) → compares its frontmatter `provider:` against the resolved provider and **refuses on mismatch** → an op's `**Mechanics:**` pointer triggers a single Read of `references/tracker/{provider}/{op}.md` → body-posting steps pass the D11 scrub (chain for file sinks, `--emit` for tool-call sinks) before the provider's post command. + +**Uninstall flow.** `~/.devflow/tracker.md` is **user content** (OD-15), sitting between `preference-profile.md` and `learning.json` in `enumerateUserDevFlowContent`. `resolveDevflowDirCleanup` needed no change — adding a `userContent` entry automatically flips a user-scope **interactive** uninstall from `'artifacts-only'` to `'prompt'`. `.tracker.processing` / `.tracker.attempts` / `.tracker.enabled` are **install artifacts** (`installArtifactPaths`), removed by an artifacts-only sweep, which **keeps** `tracker.md`. The two lists must stay disjoint (@D8). `tests/uninstall-logic.test.ts`'s 9f floor moved 5 → 6 and 9c's residue-equality set gained `tracker.md`. + +**⚠ The OD-15 reversal condition, recorded as a live obligation.** The user-content classification copies the `agent-models.json` reclassification, in which **"silently" is the load-bearing word**: stale per-agent overrides re-apply *silently*, so they were demoted to an install artifact. A stale `tracker.md` is safe to preserve **only because the mismatch guard removes the silence**. If that guard is ever dropped, descoped or softened, then **in the same change**: move `tracker.md` from `enumerateUserDevFlowContent` to `installArtifactPaths` (the reversal note is already at the code site), lower test 9f's floor back to 5, and drop `tracker.md` from 9c's residue set. The guard shipped in 3a-4, so the condition is currently **satisfied** and nothing needs reverting. + +## Integration Patterns — what registering a provider drags with it + +**Registering a provider module whose `subdir` is one of `MCP_BACKED_PROVIDER_SUBDIRS` is what OPENS the `_mcp.md` generation gate — and it is the only edit that does.** There is no flag and no frontmatter change. Two such providers are registered, and every row below is what one registration drags with it — the checklist a FOURTH provider reads, written as the end state three providers reached. + +1. **The `.mds` roster.** `MDS_REFERENCE_MODULES` in `tests/fixtures/mds-manifest.ts` holds all five reference modules; `MDS_DEFERRED_REFERENCE_MODULES` is gone, replaced by `deferredReferenceModuleSources()` in `src/core/mds-variants.ts` — the build's own deferral predicate, exported so the build and the two count guards read ONE owner. It answers `[]`, and the guards prove it still discriminates by asking it about a registry with **every gated sub-directory** removed. That probe had to be re-scoped in 3c: it named `tracker/jira` alone, so with two tool-call providers registered, dropping the first left the second holding the gate open and the arm reported the predicate as broken when it was the probe that had gone stale. **A probe that names one member of a set the gate ranges over stops discriminating the moment the set grows.** `ALL_DISCOVERED_HOSTS` is 19 and the build prints `0 reference module(s) deferred`. +2. **Floors.** `generated-reference-manifest-size` and `packed-reference-manifest-size` rose 13 → 24 → **34** (10 github + 10 jira + 10 linear + 3 cross-cutting + the contract). They pin one manifest at its two sinks and **must move together**, or a provider could ship un-packed. `capability-hoist-block-floor` moved 29 → 39 → **49** on the same rhythm: a provider adds its whole roster at once, so these floors rise by a provider rather than by a file. +3. **`tests/guards/mcp-sink-bypass.test.ts` is LIVE.** The `★ the live corpus is EMPTY at this boundary` assertion is deleted; in its place the corpus is asserted non-empty, to REACH every member of `MCP_BACKED_PROVIDER_SUBDIRS` by name, AND to hold at least one file spelling `{SCRUBBED_BODY}`: every clause arm is an empty-difference assertion, a read-only tree would clear a bare non-emptiness check, and a count is satisfied by one provider while a second provider’s tree is missing entirely (PF-064’s corpus claim — proven RED by moving `tracker/linear/` aside). Two further strengthenings landed with it: `collectBypassSites` now runs over the live corpus (it had only ever run against its own seeds — PF-064), and `POSTING_VERBS` admits a SPACE separator, because the contract mandates selection by capability DESCRIPTION (*add comment*) rather than by tool name, so `[_-]?` matched every tool name and no compliant mechanics file. +4. **`tests/guards/provider-scope.test.ts`'s AC-2.7 describe is inverted and re-armed.** The gate is OPEN for the shipped registry and SHUT for an injected registry with no tool-call provider, so GAP-02's original claim still has an assertion behind it. The *no generated GitHub mechanics file names `_mcp.md`* arm **did not relax**. +5. **`DEFERRED_REASONS` is empty** — see `### 7`. +6. **Provider literals are allowlisted per (path, token), never per token** (ADR-025). `PROVIDER_OWNED_PATHS` carries two entries per provider — the module and its generated directory — each admitting **one** token: the Jira module naming Linear is still a violation, and so is the reverse. Each entry must reach a scanned file that really carries its token, or it is deleted. AC-3.12's five forbidden scopes are asserted individually with one seeded probe each. `_mcp.mds` needed no entry — it names no provider at all. **This is what the Linear module's `## Known Unknowns` prose had to be justified against:** the rank-4 statement is about one provider specifically, so the entry's rationale says so rather than the prose being moved out of the module. +7. **The loaded set is priced per provider** — see `### 8` and the Jira table. +8. `tests/tracker/hostile-values.test.ts` ships **all four** of its named describes. `refs per provider` (row 25) needed an anchored grammar for EVERY provider, and GitHub's only came into existence in the #325 neutralisation — which is why that describe landed with it rather than with either provider module. The JQL/filter describe models §14.9-10's escape-then-drop rule as written, and scopes the drop claim to the four characters that can END a quoted literal: a query sink is not a shell, so dropping `$(id)` would cost search results while protecting nothing, and containment by POSITION is the other half of the same rule. +9. **★ `planOverlayUnits` needed a production fix in 3b, and Linear needed nothing from it** — `tracker/linear/` is an ordinary provider directory, which is the point: the shape rule below is what makes a normal provider normal. `tracker/_mcp.md` is a file landing directly in `tracker/`, and the installer overlay bucketed it as a provider directory named `tracker` — a unit whose atomic swap renames `tracker/` itself over every provider directory beside it, with a staging sibling OUTSIDE the subtree the prune converges. `D-OVERLAY-PROVIDER-SHAPE` now classifies by SHAPE (`tracker/{provider}` exactly), and everything else is a FLAT SET carrying the directory it lands in (`''` for the references root, `tracker` for the contract), with one staging name per directory. The release-blocker arm in `reference-overlay.test.ts` was widened from `tracker/github/` to EVERY manifest entry under `tracker/` — the narrow loop was green for a manifest shape the overlay could not install. +10. **`tests/installer/reference-overlay.test.ts`'s fixture provider is now `probe-provider`, not `jira`.** Its stale-prune and isolation arms need a provider the real manifest does NOT list; `jira` was one and then became real, which inverted those arms silently from "the orphan is removed" to "the real provider survives". A guard now asserts the fixture name is absent from the real manifest, so it fails loudly instead of the next time. +11. **`MARKER_REFS` in `tests/skill-references.test.ts` gained `wave` and `traceability`.** A marker namespace is not a skill, and that set is the existing mechanism for saying so — but note it is now keyed on the NAMESPACE rather than on HTML-comment syntax, because Jira's markers are visible first lines. + +12. **★ The tool-call contract got its own shared-literal registry in 3c [DR-19].** `MCP_SHARED_LITERAL_REGISTRY` in `tests/tracker/containment.test.ts` — five normative sentences `tracker/_mcp.md` OWNS (the framing line's composition, where the gated bytes come from, the transformation prohibition, select-by-description, a capability-table row), asserted present in the contract, absent from the three cross-cutting documents, and **restated in no provider `{op}.md`**. A SEPARATE registry, not rows on the sibling one, whose ownership arm asserts its owners are exactly `GIT_CROSS_CUTTING_DOCS`: folding the contract in would have relaxed that arm to admit a fourth owner instead of classifying the case (ADR-025). **The distinction that makes it work:** the contract also MANDATES literals every posting mechanic must name — `D11-OK`, ``, `SCRUB: N`, `SECRET-EXPOSED` — and a named arm asserts those are absent from the registry AND present in every posting mechanic, so this guard and `mcp-sink-bypass` cannot be satisfied only one at a time. Twenty per-op provider files written against a contract they are told to "name, not restate" will restate it; the containment oracle cannot see it, because it accounts for lines that existed pre-split. + +**Decided in 3c (#325) — the two GitHub literals Phase 2 reserved.** They were reserved because neither could be decided with one provider registered: a cell reading "Fetch GitHub issue" was simply true. + +- **`git.mds`'s `## Operations` table and two op descriptions: NEUTRALISED.** "Fetch GitHub issue", "Fetch multiple GitHub issues" and "Create or enrich a GitHub issue" are tracker operations whose provider is resolved per spawn, so the cells were right for one of three. Now "tracker issue(s)". The two op-body descriptions that duplicate those cells moved with them — left alone the table would have contradicted the operation two hundred lines below it. GitHub literals that are NOT a tracker fact stayed: `create-release` and `fetch-review-threads` name GitHub because PR and release hosting stay there under every provider. +- **`git.mds`'s digits-only `SHIPPED_ISSUES` gate: NEUTRALISED, and this one was a live defect.** Step 0 of `backlink-shipped-issues` required every entry to be "digits only" — a GitHub SHAPE in a provider-blind, always-loaded position, so under jira and linear every `PROJ-1` was dropped and the operation was unreachable. It now defers to the resolved provider's anchored reference grammar, and **the github grammar `^#?[1-9][0-9]{0,8}$` moved INTO the github reference** with the same drop rule and the canonical per-ref DEGRADED reason. **The gate is relocated, not weakened:** the operation always loads its provider reference, and an absent reference already means `tracker mechanics unavailable` with no tracker call, so the fail-closed property holds. The metacharacter rationale went with it — all three provider mechanics say the anchored form is what keeps a reference out of a query or a command, and `## Tracker input contract` already states shape-gate-at-the-sink once, so restating it in step 0 was the duplication GAP-37 forbids. +- **`backlink-shipped-issues`' own D4 line no longer names a GitHub signal, and that is the LAST always-loaded site (#325 alignment pass).** The op-level clause read *"Secondary rate limit (403/429 rate-limit response or `X-RateLimit-Remaining` < 10) → stop immediately"* in a provider-blind position, so under jira and linear the winning contract keyed the full-STOP rung on a header neither provider sends while both modules state there is no pre-emptive rung at all. It was **deleted rather than reworded**: the always-loaded D4 block already states the rung provider-neutrally and defers the signal to "the resolved provider's reference", names this op among its two batch ops, and `### Provider signals (GitHub)` in the github mechanics holds both thresholds. A pointer sentence restating an always-loaded rule is the GAP-37 duplication the step-0 pass on this same operation already removed once. **`resolve-review-threads` keeps both thresholds** — PR-thread hosting is GitHub under every provider — and `tests/provider-literals.test.ts` asserts exactly that split per file, with a control arm so an agent scrubbed of backpressure entirely cannot satisfy the absence half. **Why the P2-S4 detector guard never caught it:** `collectCrossCuttingSections` scans `(header)`, `## Principles` and `## Boundaries` only. Excluding op bodies is right for a non-tracker op, whose provider is fixed — and wrong for a TRACKER op, whose provider is resolved per spawn. Look at tracker-op bodies by hand; the guard will not. +- **`src/assets/skills/git/SKILL.md`'s `X-RateLimit-Remaining` threshold: KEPT, deliberately.** It is a load-bearing GitHub D4 mitigation in a file the GitHub path preloads, `SKILL.md` has 19 ch of headroom, and the skill carries GitHub doctrine rather than provider-neutral contract. **Recorded here as a retained GitHub literal so its survival reads as a decision rather than an oversight.** + +Net effect on the always-loaded file: **58,776 → 58,751 ch and one line shorter**, so every budget row gained headroom rather than spending it — which matters because the Jira row had 51 ch and an earlier, wordier draft of the same neutralisation breached it. Six baseline lines are booked in `CONTAINMENT_EXEMPTIONS` tagged `#325.`; these are rewrites, not moves. + +**Not taken in 3a, recorded so the absence reads as a decision:** the optional per-run **capability attestation line** [GAP-48]. P3a-S14 calls it optional; it has no named consumer and every always-loaded character costs against 94 ch of headroom (ADR-003). It was not added in 3b or 3c either; if a later phase wants it, it belongs in a **per-op Output block**, never the preamble. + +## Provider: Jira (3b) + +`src/assets/mds/tracker/_jira.mds` → `dist/skills/git/references/tracker/jira/{op}.md`, one file per tracker op. Registered in `VARIANT_MODULES` with `subdir: 'tracker/jira'`, `kind: 'fanout'`, `ops: TRACKER_OPS`. Guards: `tests/tracker/jira-module.test.ts` (31 cases). + +### Parity is structural, not asserted + +`TRACKER_OPS` is the roster and **every provider row reads it**, so file-set parity across providers is a compile-time property: a provider cannot gain or lose an operation without every provider moving with it. `TRACKER_GITHUB_OPS` remains as a named **alias** of the same list, because several guards genuinely mean *the GitHub path's ops* rather than *the roster* — the GitHub-scoped loaded-set row, the re-scoped AC-2.7 arm, the containment oracle's github corpus. The two are asserted identical by `toBe` at the registration sites, so this is one list with two readings rather than a synonym nobody maintains. + +**Define-set parity is asserted**, both directions, because a `@define` name is visible to no type. At three providers the scan is what §8.11 calls non-vacuous, and its shape changed with the third column: `PROVIDERS` is now **derived from the registry's provider rows** (so a fourth joins by construction) and the two hand-written directions became one loop over every **ordered pair** — six directions, not two, because writing them out would be six places a message could drift. `providers.length === 3` and the column names are both asserted, so a registry that lost a provider shrinks the scan loudly. + +Three claims ride with it: the define roster equals the op roster with hyphens as underscores; every define body clears an 80-character floor (three modules can agree perfectly on a set of empty defines); and **every §14.4 matrix cell is filled** — each define either states what the operation does on that provider or names why it cannot, with the two known-undefined cells (`closing_refs_for_commit` on Linear and on Jira) asserted POSITIVELY so "no blanks" cannot be met by a module quietly claiming support it does not have. + +### Provider facts, and the ones that must be ABSENT + +| Fact | Value | Why the absence matters as much as the presence | +|---|---|---| +| `size_cap` | `32767` | The truncation floor derives from it and from the Bash-result limit in `platform-assumptions.md` [DR-06(c)] | +| rate-limit signal | `Retry-After`, honoured **verbatim**, STOP on 429 | **Reactive only.** `X-RateLimit-Remaining` is **absent from the module**: Jira publishes no remaining-request count, so a pre-emptive rung keyed on one would never engage and would read as coverage while providing none | +| GitHub's cap | `60000` **absent** | §14.2 resolves GAP-13 by rendering the 60k sentence verbatim on the GitHub path and each other provider's own cap elsewhere — one number per provider, never a parameterised one | + +### The dedup ladder, and the marker + +Rungs in order, each named by **capability description, never by tool name** (the contract's rule, and what keeps [DR-08]'s negative unambiguous): *entity property read/write* → *edit comment in place* → *list comments with authors* filtered on the hoisted `accountId` from *identify current user* → **post-with-warning** (`TRACEABILITY: DEGRADED (dedup unavailable — duplicate possible)` and post anyway). + +**The marker is the comment's FIRST LINE and nothing else.** Jira's comment format has no HTML-comment node — which is also why `render_collapsed_block` degrades to a pointer sentence — so the marker is visible prose on line 1, matched for equality. A marker on any later line **does not suppress**: a marker at line 5 of a third-party comment is quoted prose, and a substring search over the whole comment is exactly how a quoter acquires the power to silence a release note. + +**Markers are namespaced per comment kind, and each namespace has exactly one owning operation:** + +| Namespace | Owner | Line-1 form | +|---|---|---| +| `devflow:shipped` | `backlink-shipped-issues` | `devflow:shipped v{BARE_VERSION}` | +| `devflow:wave` | `post-wave-report` | `devflow:wave {WAVE_ID}` | +| `devflow:traceability` | `ensure-traceable-issue` | `devflow:traceability {ISSUE_REF}` | + +A single global marker would make the three kinds **mutually suppress** (GAP-20) — one kind's comment satisfying another kind's dedup predicate.

Under GitHub each item's marker check is one call; under Jira rung 3 is the *default* landing rung and each check is a paged comment listing filtered client-side, so the op-level cost is a product no per-call bound expresses. All three literals are pinned and a test asserts the arithmetic (a page bound raised to `≤4` with the product left at `≤100` is the drift that catches). The module also states the **structural** preference [DR-09] names: hoist one bounded *list by filter* read over the ≤50 keys and match markers in memory — one read instead of a hundred. + +### `fetch-issues-batch` is ONE query [DR-08] + +`key in (KEY-1, KEY-2, …)` with an explicit `maxResults`, bounded `≤50` with `TRUNCATED ({n} not processed)`, **never a per-item loop**. The guard forbids two classes of per-item shape in that file: tool-name verbs (`getJiraIssue`, `get_issue`) and the single-key **capability** name (`fetch by key`) — a guard covering only the first would be inert against the module this repo's own capability-first doctrine steers an author towards writing. `fetch-issue` is in the table too, so the batch reference names the sibling op by description rather than by name; both classes are driven by seeded fixtures. + +### JQL / filter safety — stated once, where free prose reaches a query + +`ensure-traceable-issue`'s `### Query safety`, and nowhere else: it is the only op where caller-supplied prose reaches a query (`manage-debt`'s search uses a structured filter, and the batch filter carries only pre-flight-anchored keys, so neither has an escaping question). Prefer a structured filter argument; a value may appear **only as a quoted string literal** and only in value position, never as a field, an operator or an ordering clause; escape `\` first and then `"`; after escaping **drop** anything still carrying `"`, `\`, a newline or a backtick — repair is forbidden; every query carries the `≤50` bound plus `TRUNCATED`. + +### The ref grammar, and AC-3.4 + +`^[A-Z][A-Z0-9_]{1,9}-[1-9][0-9]{0,8}$`, **anchored at both ends** — never `^A|B$`.

The Jira reference states its anchored grammar as *that gate instantiated for this provider* (the metacharacter guarantee the gate exists for is what the anchored form provides), which is the only reading that does not require editing `git.mds`. A cleaner end state moves the digits-only clause into the github reference; that is a preamble-adjacent edit and was deliberately not taken here. + +### Every op carries a named DEGRADED (AC-3.3) + +Jira absent or denied yields a **named** DEGRADED at each tracker op — `no tracker tool for {capability}`, with the capability named — while **the branch is still cut and the PR is still opened**, carrying `Tracked (pending)` and the reason. **Never a GitHub issue as a fallback:** a different tracker is not a degraded version of this one, and a stray issue on another system is worse than an honest gap. `setup-task` additionally owns `unusable site` (the `## Project` site shape gate), `tracker not configured` (no site or key), `ambiguous issue reference` (a bare number) and `unsupported transition` (a state `## Transitions` names that this run did not enumerate). + +### Posting: the contract is NAMED, never restated + +Four ops post (`manage-debt`, `backlink-shipped-issues`, `ensure-traceable-issue`, `post-wave-report`). Each carries a `### Posting gate` that **names `references/tracker/_mcp.md`** and lists its steps without restating its rules: compose into a fresh `mktemp` `$DEVFLOW_BODY_RAW`, run `redact-secrets.cjs --emit`, require a `D11-OK` line, verify ``, echo `SCRUB: N […]`, emit `SECRET-EXPOSED (rotate {type} credential — the source file still holds it)` when N > 0, and post with the body argument `{SCRUBBED_BODY}`. AC-3.18 holds absolutely: no `curl`, no `wget`, no `Authorization:`, no credential from the environment, no command-line client anywhere in the tree. + +### The Jira loaded-set row + +Every term below is a row `tests/tracker/byte-budget.test.ts`'s shape table prints: + +| Term | ch | +|---|---| +| always-preloaded set (`git.md` 58,782 + git `SKILL.md` 6,581 + worktree-support 2,942) | 68,305 | +| `references/tracker/_mcp.md` — **0 on the GitHub path**, per-spawn here | 6,402 | +| `max_op` `tracker/jira/{op}.md` (`backlink-shipped-issues`) | 6,087 | +| max over jira ops of the one-spawn load (`setup-task` + `learn-conventions.md`) | 7,821 | +| **worst-case Jira spawn** | **88,615** | + +`BUDGET_LOADED_SET_JIRA = 88_660` — headroom **45**, a NEW registered ceiling (`budget-loaded-set-jira`), never a raise of an existing one.

With no author column to compare against, the marker is the only evidence a comment is devflow's, and `devflow:shipped v1.2.3` is a first line somebody discussing a release might plausibly type. A full project URL on the same line is not. Danger JS's `"Generated by"` trick, hardened. + +**The URL is part of the MARKER, not a visible footer.** `git.md`'s attribution rule confines the `*Posted by [devflow](…)*` footer to `post-review-summary` and `post-resolution-summary`; these three comment kinds "use the marker only", and a footer here would contradict an always-loaded rule. A guard asserts every namespace appears on a line that also carries the URL, in all three kinds, because a kind that dropped it would dedup on the marker alone and inherit the false positive rank 4 cannot otherwise rule out. + +**§14.4's spellings, not GitHub's.** `devflow:wave`, deliberately, against GitHub's frozen `devflow:wave-report` — and a negative arm asserts GitHub's spelling never leaks in, so it cannot be "fixed" by copying the sibling across.

An unnamed `400` is therefore answered by continuing to fan out **into** the window the rung exists to stop, which is the one way this provider's backpressure is missed entirely. The module names the code, the token, the error-text form, and `STOP` — and states that there is **no pre-emptive rung**, because an omitted rung reads as an oversight and the next author adds GitHub's. + +### The ref grammar — two anchored forms, never one alternation + +`^[A-Z][A-Z0-9]{0,9}-[1-9][0-9]{0,8}$` **or** `^[0-9A-F]{8}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{4}-[0-9A-F]{12}$`, each anchored at both ends, after **ASCII-upper normalisation** (a reference copied out of a branch name or a URL arrives lowercased). §14.1's "never `^A|B$`" is the whole point: an alternation inside one anchor pair anchors the left branch at the start only and the right at the end only, and `tests/tracker/hostile-values.test.ts` drives that exact shape as a probe to show it admits a payload every shipped form rejects. + +The always-loaded entry gate in `backlink-shipped-issues` step 0 now defers to this grammar rather than requiring digits — see `## Component Interactions`' note on the #325 neutralisation. + +### The call budget [DR-09] — the common path, not the edge + +`≤50` items × `≤2` pages = **`≤100`** marker calls, with the hoisted single-pass alternative stated beside it.

Check this number, not that one, before adding always-loaded text. **This provider's `max_op` is the largest of the three in the printed table, and that is content rather than slack:** `backlink-shipped-issues` is where the ladder is stated, three of its four rungs need their unavailability explained (or the next reader treats rank 4 as a misconfiguration), and the marker predicate needs both halves written down.

That is not a filing preference: a column-0 `## ` inside a generated reference terminates its operation section for every guard reading it through `extractOpSectionFromCorpus`, so everything below would go silently invisible while the bytes stayed on disk (PF-063). A guard asserts the heading is above the first marker AND absent from all ten generated files.

The validated token selects a **hardcoded path prefix from a static map** and is never concatenated into a path; **never `?? id`**, because falling back to the raw ID is exactly the echo the map exists to prevent. Compliance's `normalizeId` is the shape *not* to copy. +- **Adding `features.tracker` to `readManifest`'s hard-null set.** It makes every pre-tracker manifest read as "no prior install". The field's tolerant parse is the design, and its doc comment carries the prohibition. +- **A negative provider test (`!= github`) anywhere.** `manifest.json` is user-writable; a negative test admits every hostile string that merely is not the word "github", including quote-and-newline injection, straight into `additionalContext`. Always a positive allowlist, always before interpolation. +- **Inlining an `fs.rm` of `.tracker.attempts`, or writing `.tracker.enabled` without the removal arm.** Both have one owner each; the second is PF-015's write-without-remove asymmetry, which leaves a GitHub user paying forever for a provider they switched away from. +- **Reading the `--reset`-gated seed for the rename's `previous` provider.** Under `--reset` the resolved provider is `github` while the prior one is still `jira` — a real transition the rename must fire on (EC-62). +- **Writing a defaults-only or partial `tracker.md` "to make progress."** The file's existence is the signal that setup is done; the session-start gate reads nothing else. A partial file **permanently suppresses** the retry that would have produced a correct one, which is why "write the whole file once or write nothing" is the agent's Iron Law and why no-capability-reachable writes nothing at all. +- **Naming a provider, or the transport acronym, in the Tracker agent or in `_mcp.mds`.** Beyond the `provider-scope` guard, re-deriving a provider in the prompt is a second convergence point (PF-023), and "MCP" in user-facing text leaks transport into copy the user reads. +- **Using the noun "valid" + "ator" anywhere in a shipped asset.** It is a **retired agent name**, and `agent-name-guards`'s GAP-5 sweep matches retired form-B names with maximal recall (case-insensitive, no trailing boundary) over `src/assets/**`. The agent's column is therefore **"Shape gate at the sink"** and the prose says *shape gate*. (`"validation"` is safe — it does not contain the substring.) `RETIRED_ALLOWLIST` is context-scoped to stable identifiers, never flowing prose, so rewording is the precedent-consistent fix. +- **Re-pointing the `tracker.md` write at `--emit`.** A file sink has a shell `&&` available and that chain *is* the gate; framed stdout exists for sinks with no such boundary. The agent states the two reasons **separately** and `tests/tracker-agent.test.ts` asserts the agent does not contain `--emit`, precisely so a later "simplification" cannot collapse them. +- **Reading the remote, the hosting platform or the PR host as a provider signal.** OD-9 names this WRONG and says it must never be implemented. Devflow itself is the counterexample: GitHub PRs, Jira tracker. +- **Giving a tool-call provider's comment a visible `*Posted by [devflow](…)*` footer.** `git.md` confines that footer to `post-review-summary` and `post-resolution-summary`; `post-wave-report`, `backlink-shipped-issues` and `ensure-traceable-issue` "use the marker only". Linear needs a second discriminator on top of its marker (rank 4 has no author column), and the answer was to put the project URL **inside the marker line** rather than to add a footer — a footer would contradict an always-loaded rule to solve a problem the marker can solve itself. +- **Adding a `- **Tracker**:` line to an operation's Output template.** §14.2 says the GitHub path emits no tracker status line at all; an unconditional template line is a defect, and the frozen fixture is what catches it. +- **Adding a `_roster.mds` row or a registry exemption for `tracker`.** The commands-less-plugin pass is structural. A roster row fails `inRosterNotInDist`, and the roster resolver throws on a name it cannot read. + +## Gotchas + +- **`grep` treats a file with a NUL byte as binary and skips it silently.** `src/core/tracker.ts` originally wrote `describeTrackerValue`'s character class with **raw** `\x00`/`\x1f`/`\x7f` bytes, so `grep -n "^export" src/core/tracker.ts` returned `Binary file matches` and **every repo-wide grep guard over `src/core/` silently missed the file**. Fixed to `/[\x00-\x1f\x7f]/g` (behaviour-identical) with `tests/guards/no-control-bytes.test.ts` as the permanent detector. When a guard "passes" over a file, confirm the file was actually read. +- **Two `gh`-shaped traps for anyone editing the Git agent's preamble**, both of which bit 3a-4 and both fixed in the prose rather than by widening a guard: a `` `gh` `` code span **anywhere** in cross-cutting text fails `git-agent.test.ts`'s P2-S4 provider-detector guard (state the prohibition without naming the CLI); and a mid-line `## Operation: ` literal is read by the op-roster scan as a **real operation** (with the trailing backtick in its name) and breaks three unrelated op-scoped guards — name an operation as `` the `learn-conventions` operation ``. +- **The hook and the agent both classify the claim file, and nothing at runtime reconciles them.** `TRACKER_PROCESSING_STALE_SECS=600` in the hook and the `**600 seconds**` literal in the agent's Step 0 must be equal, or the larger side suppresses what the smaller side re-arms: inference stalls, or an OD-14 attempt burns every session until the cap closes the feature. `tests/seams/tracker-claim-staleness.test.ts` is the only place the two are compared; it reports an *unstated* bound rather than reading it as agreement, and it cannot tell you 600 is the wrong number — only that both sides still say the same one. +- **The hook overwrites the counter on every emission, so the agent's format only matters for the agent's own increments.** A count the agent writes in any other shape is not a smaller count — it is no count at all, self-healed to `0` by the hook's `case`. Both sides now pin "one decimal-integer line and nothing else." +- **`tests/config-disable-guards.test.ts` used to run `session-start-context` against the real `$HOME`.** Four invocations in that describe did, and with a developer's own machine configured for `jira` the `expect(output).toBe('')` assertions saw the full `--- TRACKER SETUP ---` envelope. Every invocation there now carries a seeded temp `HOME` **and** `DEVFLOW_DIR=''` (AC-3.22). A hook test that reads the real `$HOME` is a test whose result depends on who runs it. +- **A deferred reference module is not a partial and not a refusal.** `partialCount = totalCount - hosts.length - deferred.length` in `scripts/build-mds.ts`; an *unregistered* reference module is still refused with the registry-naming message. `npm run build` reports `16 compiled, 1 deferred, 0 errors, 0 warnings` at the 3a boundary — the deferral line is expected output, not a warning. +- **`resolveAgentSource` prefers `dist/agents/`.** `tracker.md` is hand-authored, so there is no `dist/agents/tracker.md` and the src file is read — but a stale dist artifact from an unrelated experiment would silently shadow every edit and every guard. If an agent edit appears to have no effect on its guards, check `dist/agents/` first. +- **`devflow tracker` with no flag prints usage and returns 0.** It is not an error path, and the usage note deliberately says *"github is the default — `devflow tracker --set github` turns the rest off"* rather than naming a `--no-tracker` that does not exist. +- **The Tracker agent's summary is invisible.** It runs in the background with `run_in_background: true` and nobody reads its output block, which is why **every uncertainty goes into the file as a `# UNRESOLVED:` sentinel or a `### Substitutions` row rather than into a message.** When debugging a bad inference, read `~/.devflow/tracker.md` — its `inferred-from:` provenance line is the only record of which root was scanned and when. +- **The bypass regex reads `word:` as an argument assignment, and prose is full of them.** `tests/guards/mcp-sink-bypass.test.ts` matches `(body|description|content|text|markdown|adf|comment_body)\s*[:=]\s*` followed by anything other than the gated placeholder. A sentence like *"the detector must read the text: a status-shaped rule…"* is therefore reported as a posting mechanic assigning an ungated body — it caught three prose false positives in 3b and one more in 3c. **Write mechanics, not prose that looks like a call**: "read that error text and not the status" costs nothing and the guard stays unambiguous. Do not widen the regex to exclude prose; the widening would exclude the real shapes too. +- **A provider module's `max_op` is what the byte budget prices, so the LARGEST op file is the one to watch.** Linear's `backlink-shipped-issues` is 7,706 ch, the largest `max_op` of the three in the printed table, because the dedup ladder and the rank-4 marker predicate are both stated there. That is priced on its own row and justified in the ceiling's JSDoc, but the lesson generalises: content added to whichever op file is already the biggest moves a ceiling, while the same content in any other op file moves nothing. Check `max_op` before choosing where a cross-cutting paragraph goes. +- **The agent is 334+ lines against the plan's ~250 estimate, and that is a decision.** 82 lines are irreducible contract (the 11-row shape-gate table plus the 46-line template); the rest is prose whose every paragraph carries a rule *with* its reason, because PF-037 argues for self-containment for an agent that runs unattended with no orchestrator to ask. One trimming pass was attempted and immediately tripped two guards.

Do **not** rename either in Phase 2. +- **The `## Operations` contract table's provider-specific wording was Phase 3's to decide, and Phase 3 decided it (#325).** Phase 2 left the always-loaded table reading "Fetch GitHub issue" / "Fetch multiple GitHub issues" while D4, D11, the Principles and the Boundaries were all neutralised to "the tracker". The asymmetry was deliberate on two grounds — the table is contract prose, outside the mechanics-move charter, and every character of it lands against `git.mds`'s thin headroom — and it was reserved for the point at which a second provider would make the wording actually wrong rather than merely narrow. **The three tracker cells are now "tracker issue(s)", together with the two op-body descriptions that duplicate them**, because a table contradicting the operation two hundred lines below it is a worse end state than either wording alone. `create-release` and `fetch-review-threads` still name GitHub: PR and release hosting stay there under every provider, so those are not tracker facts. **`src/assets/skills/git/SKILL.md`'s `X-RateLimit-Remaining` threshold was KEPT**, deliberately — it is a load-bearing GitHub D4 mitigation in a file the GitHub path preloads, `SKILL.md` has 19 ch of headroom, and the skill carries GitHub doctrine rather than provider-neutral contract. Recorded so its survival reads as a decision rather than an oversight. + +- **The `backlink-shipped-issues` digits-only entry gate was the same class of defect, and it was live.** Step 0 required every `SHIPPED_ISSUES` entry to be "digits only" — a GitHub shape in a provider-blind, always-loaded position, so the operation was unreachable under jira and linear. #325 made the step defer to the resolved provider's anchored reference grammar and **moved the github grammar `^#?[1-9][0-9]{0,8}$` into `_github.mds`'s `backlink_shipped_issues` define**, with the same drop rule and the canonical per-ref DEGRADED reason. The grammar was placed ABOVE the range `STATUS_LINE_REFERENCE_FILES` samples in that file (`between('1. Fetch existing comments authored by the viewer:', 'Apply the Comment-sink scrub (D11) …')`), which is why the frozen fixture stayed byte-identical: an addition outside a sampled slice is invisible to the extractor. **When adding to a reference the frozen fixture samples, check where its anchors are first.** - **A prunable flat cross-cutting root** — `sweepOrphanedReferences` is scoped strictly to `references/tracker/**`, so an orphaned flat document at the references root is never pruned. Widening it needs an allowlist of the hand-authored files that live there (`github-api.md`, `violations.md`, …), which does not exist; `D-OVERLAY-FLAT-UNIT` deliberately treats the flat set as one non-prunable unit until it does.

RESIDUE — the gate's guarantee is about the SINK, and the staging file is + * a second sink: `$DEVFLOW_BODY_RAW` holds precisely the bytes the scrub + * exists to delete (PF-066's second defect). So the always-loaded D11 block + * is asserted to REMOVE every staging file it creates, and to remove them in + * the one shape that works as shell — armed as a `trap` so a `D11-FAIL` path + * is covered too, with a plain `rm` because a permission layer refuses the + * flagged form, and with the gate's status captured ahead of the removals + * (PF-066's third defect: cleanup that runs after the gate overwrites `$?` + * and reports a refusal as success).

Both halves or +// neither: a default with no record is a silent substitution, and a record with +// no default is a report about nothing. +// +// The reference VOCABULARY differs per provider by design — jira renders a `KEY`, +// linear a `REF` — so the two spellings are parameters of the table rather than +// two tables. Nothing else varies: these clauses are contract text. +// +// EVERY ROW PINS A TOKEN, NEVER A SENTENCE — and that is a standing rule, not a +// style note.

PROVIDER LITERALS — `32767` present; `60000` and `X-RateLimit-Remaining` + * absent; `Retry-After` present (AC-3.13).
