The allow-list now includes all four (harness evolution Phase 1 hygiene) — the events record in `events.jsonl` like every other lifecycle write. **Query construction (deterministic-retrieval discipline):** build `--query` from the user's salient nouns and identifiers **verbatim** (e.g. `SYSTEM-OVERRIDE`, `payment`, `token`) — do not paraphrase intent into synonyms. The retrieval tokenizer normalizes identifier formats and morphology, but it cannot recover a term the query never contained. Passing the literal request terms is what keeps recall stable across phrasings. **Repo map & knowledge freshness (deterministic-first).** `orient` regenerates `.harness/repo-map.md` every turn from `git ls-files` + a lexical symbol/import extractor — so code orientation is always current and never depends on a model. `init-repo` and `index` additionally write a committed, timestamp-free `docs/codebase-map.md` (~2.5k-token budget, query-less) so cold-start agents read one durable orientation file instead of exploring. Learnings (semantic memory) live in a local never-pushed git store at `~/.harness/knowledge//`; `orient` injects the top-3 trigger-matched learnings inside the existing 2 KB pack, attributed by id, with insight-derived claims fenced `[unverified memory — advisory]`. The `.harness/repo-map.md` (like `.harness/context-pack.md`) is an ephemeral derived artifact, not a persistent type. The knowledge index is refreshed manually (`harness index`) — run it after a major pull from main or a docs rewrite; `index --status` and the `orient` next-hint tell you when it has drifted. A staleness-or-intent maintenance refresh may additionally re-derive conventions via `/codebase-context` (an optional, cheap, non-reasoning model pass) and promote generalizable solution docs to the global `~/.copilot/knowledge` store (episodes only — never the learnings store, whose sole writer is `consolidate --apply`) — never per turn. The extractor is a seam: a tree-sitter tier (WASM, lazy-loaded grammars, lexical fallback for SQL/HCL) can implement the same `extract` shape to power symbol-accurate `refs`/`def`/`callers`, built only when telemetry shows the lexical map misleads the agent. +**Structural index (optional tier — Phase 3).** `harness index --structural [--since ]` builds a persistent, derived symbol index at `~/.harness/index///structural/` (`files.json`, `symbols.json`, `graph.json`, `meta.json` with the `{sha, branch, baseSha, generatedAt}` generation stamp). The path is keyed per WORKTREE as well as per repo: worktrees of one repo share a `repo-id` and can sit at the same `meta.sha` with different working-tree content, so a single directory would serve each worktree the other's tables. Parsing uses optional web-tree-sitter WASM grammars (TypeScript/JavaScript/TSX, Python, Java); any other language, missing grammar, parse failure, or init failure falls back **per file** to the lexical extractor, so the harness works fully with the optional grammar packages absent — the lexical tier records real export flags (JS/TS `export` forms and CommonJS, Python `__all__` or module-level public defs, Java `public` members) plus explicit named-import references, so the structural checks are meaningful with no grammar installed. `grammars.lock` pins a sha256 digest per wasm AND for the JS loader entry point the dynamic import executes, both verified before instantiation; a mismatch is a **loud** lexical fallback — recorded in `meta.json` and failed (not warned) by doctor S1 — and a missing or unreadable lock refuses the treesitter tier and fails S1 rather than silently disabling verification. Rebuilds are incremental (mtime+size fast path, sha256 content confirm); `--since ` re-parses only `git diff --name-only --` files after `git rev-parse --verify` validation (leading `-` rejected), and **only when `` resolves to exactly the sha the prior index was built at** — any other ref would leave intermediate commits stale under a freshly stamped `meta.sha`, so it is ignored (reported as `sinceIgnored` and on the ledger) and the build degrades to a full incremental pass. `--since` without `--structural` is a usage error. Table caps are recorded, never silent: `meta.json` carries `symbolsTruncated` / `moduleEdgesTruncated` / `callEdgesTruncated` / `unresolvedTruncated` (table-level, where a finding could be wrong) plus `symbolDetailTruncated` (the routine per-symbol def/ref cap, which only shortens a list), and an existing-but-unreadable table is reported (doctor S1) instead of reading as empty. When `meta.sha` equals the current HEAD, `orient`'s repo map prefers the prebuilt structural tables (still a synchronous read — the async grammar lifecycle never enters orient, and a stale index is rejected from `meta.json` alone without parsing the tables); otherwise behavior is byte-identical lexical. The committed `docs/codebase-map.md` stays lexical-only so host-local index state never leaks into a committed artifact. Output follows the three-audience contract: styled ledger for humans, the bounded `--json` summary envelope below for programs (never the raw tables), and a ≤1000-token inert digest as the agent lane — raw index JSON never enters model context. The index is derived and rebuildable: deleting the directory never loses knowledge.

That + derivation makes the root a fixed function of the path; it does not by itself prove the + path *is* a store path, since the shape matches by basename anywhere on the filesystem — + so the derived root must additionally sit inside a `knowledge/` directory, the only shape + `storeDirForId` ever builds. (Without that check `writeStoreFile('~/.ssh/config.json')` + was accepted and contained against `~/.ssh`.) The + allow-list covers `learnings//.md` and its `branches//` equivalent, + the store-root metadata (`INDEX.md`, `consolidated.jsonl`, `governance.jsonl`, + `config.json`, `store.json`, `stale.json`, `.gitignore`), the bucket metadata + (`branches//INDEX.md|consolidated.jsonl|meta.json`), and the two nested files the + CLI owns (`.git/harness-txn.json`, `.lock/owner.json`). A planted symlink is therefore + never read through, never written through, never appended through, never deleted through, + never listed as an active learning by `harness learnings` / retrieval / ranking, never + copied into the workspace mirror under `knowledge commit repo` — and, critically, never + `existsSync`-trusted into "already fine": `existsSync` FOLLOWS a link, so the store now + asks `storeFileState`, which reports `symlink`, never `file`. + Scoping this to learning files was wrong for exactly the reason the store `.gitignore` + was already inside the choke point: the store root is a directory a human writes to, so + every metadata file in it is as plantable as a learning path. `ln -sf ~/.zshrc + /INDEX.md` plus any command that rebuilds the index — retire, dispute, confirm, + promote, apply, absorb, purge, rebuild — truncated and replaced that outside file. + **The link itself is quarantined.** Refusing to follow it while leaving it standing was + not enough — it still looked like a real file to anything that only read the directory + listing, and the next writer met a live link. A write through the choke point MOVES the + link (never its target; `rename` does not follow a symlink) into `/.quarantine/` + and writes the real file in its place; `absorbHandEdits` does the same for a learning + path and logs where it went. `.quarantine/` is gitignored, so a quarantined link never + enters store history and is never swept by `git clean -fd`. + A **filter-rewrite** (purge's ledger/governance rewrites) additionally fails CLOSED when + the file exists but could not be read: writing a filtered version of a file you never saw + is a truncation. An **append** never becomes a read-modify-write for the same reason — it + is a real `O_NOFOLLOW|O_APPEND` write, so a ledger too large to read whole is still + appendable rather than silently truncated by its next append. And a refused write, + append, or truncate throws rather than returning quietly: a store write nobody checked is + the same defect class as a rollback nobody checked. +- **A tracked learning replaced by a symlink is quarantined too.** Replacing a *tracked* + file with a link is a git TYPECHANGE — `git status` emits ` T`, which is neither `??` nor + contains `M`. The absorb loop's status-code filter ran BEFORE the symlink branch, so + ` T` (and staged `A `) `continue`d: never quarantined, never logged, and the next + `git add -A` committed the symlink into store history while `listLearnings` silently + dropped the learning. The symlink check now runs before any code filter that could + exclude it, and the filter itself is an allow-list (`??`, `M`, `A`, `T`) rather than a + deny-list. The unmerged codes are carved out **before** any code is interpreted: `DD`, + `UD` and `DU` all contain a literal `D`, so while the carve-out sat below the deletion + branch an unresolved conflict was recorded as a hand deletion — a governance `retire` + that binds both layers and survives `consolidate --rebuild`. +- **A symlink at a store-owned DIRECTORY is quarantined, restored, and then refused.** + The choke point's allow-list covers file *leaves*, and the absorb loop's learning-path + regex matches `…//.md` — so a symlink at `/learnings`, a domain + directory, `/branches`, a bucket, or a bucket's learnings tree produced **no + absorb entry at all**: nothing quarantined it, every read path silently returned nothing + (the ancestor walk correctly refuses the whole subtree), and the next `git add -A` + recorded the link as a `120000` blob while the CLI reported success. Once tracked it is + self-reviving — every rollback `git reset --hard` re-materializes it, and `git clean -fd` + cannot sweep a tracked path. There is no arbitrary-file read or write in it (git stores + the link's target *path*, not the target's bytes, and writes still refuse via the + ancestor walk); it is silent, committed, reported-as-success **data loss**. + Two guards close it. `withStoreTransaction` sweeps the owned directory shapes as the + first thing it does under the lock — before crash recovery, before `fn`, before any git + read — quarantines each planted link, recreates the real directory, restores the subtree + from the last commit so the hidden learnings **reappear**, and then refuses *this* run + naming the directory. And `commitStore` — the one place `git add -A` runs — refuses to + stage at all while such a link stands, so no present or future caller can reach staging + around the sweep. +- **The store lock cannot be lost, and is never released by a non-owner.** The first + transaction to open a store writes (and, for stores created by an older CLI, migrates in) + a `/.gitignore` covering `/.lock/`, `/.lock.stale-*`, and `/.quarantine/`. It is + written **under the lock** — writing it is a store mutation, and `ensureStore` runs before + the lock is acquired — and an existing `.gitignore` that cannot be read for a reason other + than "it is a symlink" is left exactly as found rather than replaced. That file is what + makes lock loss structurally impossible rather than recoverable: the transaction rollback + runs `git clean -fd`, which used to sweep the untracked `.lock` out from under the very + transaction holding it, after which the code re-asserted with a bare `mkdir` and swallowed + `EEXIST` as "still there" — so if a second writer had claimed the freed lock in that + window, the first carried on inside a lock it no longer held, `git add -A`-ed the other + writer's in-flight files, and finally deleted THEIR lock. `git clean` without `-x` never + touches an ignored path and `git add -A` never stages one, so the window is gone. + Independently of that, every lock carries an **owner token** (pid + random nonce) written + inside the lock directory at acquisition. Re-assert and release both verify it: a lock + whose owner stamp names somebody else (or cannot be read) is never reclaimed and never + removed, and a transaction that discovers its lock has been taken over aborts instead of + continuing. A lock whose owner stamp could NOT be written **fails the acquisition** and is + removed again: leaving one live wedged the store for the full ten-minute staleness window, + because nobody — including its own creator — could then prove ownership to release it. + The store `.gitignore` is additive — entries a human added are preserved. +- **Stale-lock takeover is a compare-and-swap, not a narrowed race.** Taking over a lock + older than ten minutes renames it to a tombstone whose name is DERIVED FROM THE IDENTITY + OBSERVED BEFORE THE RENAME, so the rename itself is the atomic swap: a second writer that + observed the same stale lock finds that exact tombstone in its way and fails. If it does + win the rename (the first writer already cleaned its tombstone up), the post-swap verify + catches that what it moved is not what it observed, and it puts the live lock straight + back. Previously both writers renamed, re-created, stamped and verified in turn, and both + returned "acquired". +- **A transaction never clears a journal it does not own.** The intent journal is one shared + file, and clearing it used to be unconditional: a writer whose recovery rollback lost the + lock still removed the journal the WINNING writer had just written, leaving that writer + running unmarked — the exact state the fail-closed journal check exists to prevent, + reached from the other side. A journal now carries the same owner token its writer's lock + does, and is cleared only by its owner. Crash recovery is the one legitimate foreign + clear: it consumes a dead writer's journal under a freshly acquired lock. +- **A rollback that failed is reported as failed.** `rollbackStore` checks both git + invocations AND re-reads the tree afterwards (a zero exit is not the same thing as a clean + tree), and a transaction that could not roll back what it meant to discard NEVER reaches + its commit — enforced in `withStoreTransaction` itself, not left to each caller to + remember. This is what makes the write-time `E_HEAD_MOVED` rejection's "nothing was + written" promise true: a failed discard of the materialized branch bucket aborts the run + loudly instead of letting the finalize commit publish it. +- **`git status --porcelain` is always read with `-z`.** The line-oriented format C-quotes + and octal-escapes any path containing a non-ASCII byte, a quote, a backslash, or a control + char, and separates rename pairs with an in-band `" -> "`. Both are lossy: a hand edit to + `learnings/café/x.md` decoded as `learnings/caf303251/x.md`, and an ordinary file named + `learnings/a -> b/c.md` decoded as `b/c.md` — so residue discard silently no-opped WHILE + REPORTING SUCCESS, absorb missed the same file, and the next commit's `git add -A` swept it + into history unvalidated and unscanned. `-z` emits pathnames verbatim (NUL cannot occur in + a pathname) with the rename pair as two separate fields; one parser serves every consumer. +- **Crash residue is not a hand edit.** Every store transaction writes an intent journal + under the store's `.git/` before its first mutation and clears it on commit or rollback, + so a writer killed mid-transaction leaves uncommitted state the next transaction can + positively identify as CLI-authored: it is rolled back to the dead writer's last + checkpoint (any intra-transaction commit it did land, such as an absorbed hand edit, + survives) instead of being absorbed as human authority. Dirt found with no journal behind + it is a genuine hand edit and absorbs exactly as described above. **The decision is + per-path**, not tree-wide: the journal records WHICH paths were already uncommitted when + it was written, and only paths dirty now that were not dirty then count as residue. A + tree-wide flag was too coarse — absorb deliberately ignores non-learning files + (`config.json`, `INDEX.md`, a scratch note), so one sitting uncommitted disarmed residue + rollback for the learning paths a later crash dirtied. **A journal that cannot be written + refuses the transaction** rather than running unmarked: the journal is the only thing that + tells residue from a hand edit, so proceeding without one is exactly the state whose + residue is later laundered into `source: human`. A checkpoint refresh that FAILS after an + intra-transaction commit aborts the transaction too, rather than leaving the previous + journal in place: the previous journal names an OLDER checkpoint, and recovery resets + `--hard` to exactly that sha — destroying the sub-commit that had just landed, which for + `absorbOrAbort` is an absorbed human hand edit. **A recovery whose rollback could not + clean the tree refuses the run**: the fallback rollback's result used to be discarded, so + a residue that survived both attempts was reported as recovered and inherited by the next + transaction's absorb as human authority. +- **Every rollback goes through the transaction's own guard.** `rollbackToCheckpoint` + unwinds to the last checkpoint; `rollbackUncommitted` discards only what is uncommitted, + for an `fn` undoing its own failed sub-commit attempt (the quarantine-strike recorder). + Both set the "this transaction could not discard what it meant to discard" latch and + re-assert lock ownership afterwards. No `fn` calls `rollbackStore` directly any more: the + strike recorder's bare call was the last `git clean -fd` in the codebase that could free + the lock with nobody checking who held it next. Use `harness remember` to add a new claim and `harness learning retire|dispute|confirm` to change a learning's status when a CLI command is more convenient than a direct edit — both remain first-class paths; hand-editing is no longer a discouraged shortcut, it is absorbed with full provenance either way. +## Layered store: branch-local knowledge (shipped, blueprint Phases 1–2) + +The approved [Harness Evolution Blueprint](../knowledge/proposals/harness-evolution-blueprint.md) +(Human Decision 2026-08-06) Phases 1–2 are implemented. Current behavior: + +- **Layout.** Golden remains `learnings/` at the store root; branch-local layers live at + `branches//` siblings, each with its own `learnings/`, per-bucket + `consolidated.jsonl`, `INDEX.md`, and a `meta.json` cache + (`{ branch, branchKey, baseSha, createdAt, promotable }` — a cache, never authority: + promotability is derived from the key shape at decision time, and `detached-*` keys are + never promotable). `ensureStore` stamps `store.json { schema: 2 }`; a CLI older than a + store's recorded schema refuses with an upgrade hint instead of operating layer-blind. +- **Branch keys.** `-<8hex>` — the branch name lowercased with everything outside + `[a-z0-9._-]` collapsed to `-`, capped at 64 chars, plus the first 8 hex of sha256 over + the RAW name (`git-context.mjs`). Detached HEAD (including rebase/bisect states) derives + `detached-<12-char-short-sha>`. +- **Provenance.** Episodes captured by the CLI and learnings written by `consolidate + --apply` carry optional `commit:`/`branch:`/`base:` frontmatter. Both learning + serializers emit AND preserve the fields across every re-render (STRENGTHEN, hand-edit + absorb, purge delink); legacy artifacts without them never error. The + `LEARNING_BYTE_CAP` check excludes the provenance lines from the measured size, so a + near-cap learning gaining provenance can never trip `E_BYTE_CAP` or a quarantine strike. +- **Write routing** is derived from git context AT WRITE TIME: feature branch → + bucket; default branch → golden; detached → detached bucket. Default-branch resolution is + store `config.json` `defaultBranch` → `origin/HEAD` → unresolved, and an unresolved + default fails closed TO BRANCH-LOCAL, never golden (doctor K7 surfaces it). The + orient-recorded branch is advisory only — a write whose HEAD disagrees warns. +- **Layer containment (what the boundary is, and what it is not).** "Promotion is the only + branch → golden route" is a containment claim, so the flag that bypasses routing is + gated like every other human-authority path in this store: `--layer golden` is an + explicit, logged override that requires the human-presence signal — a live human + (`harness remember`'s internal `humanPresent`, which the ops JSON can never assert) or an + explicit `--yes` after a person reviewed the ops file. Without it the run is refused with + `E_LAYER`; an unattended agent cannot grant itself golden. `--layer branch` is refused + outright rather than silently ignored: branch routing is derived, and there is nothing + for a flag to override. + An episode's `branch:` frontmatter is a DIFFERENT kind of thing and must not be read as + part of that boundary: it is an ACCIDENT-PREVENTION signal (it keeps unrelated branch + work from drifting into the golden lane), not a security control. It is written by the + agent that captured the episode, nothing verifies it against git, and per-layer + eligibility (`episodeEligibleForLayer`) trusts it as-is. A dishonest `branch:` can route + an episode into the golden CANDIDATE set; what it cannot do is write golden — that still + requires standing on the default branch, or the human-gated override above, or promotion. + A workspace checkout landing mid-transaction is refused with `E_HEAD_MOVED`, and that + refusal is **side-effect-free**: HEAD is re-validated once BEFORE the run materializes or + migrates any branch bucket, and the narrower write-time re-check discards everything the + transaction did back to its checkpoint — so "nothing was written" never leaves a stale + bucket behind for the finalize commit to publish. +- **Governance is store-wide, so a branch lane never speaks for golden.** The governance + ledger binds both layers, which means a branch-local write must not append a decision + that resolves for golden. Two consequences: a re-teach landing in a BUCKET does not + append the `confirm` that would retract a standing golden `retire` (the standing decision + is reapplied to the bucket copy instead, and the CLI says so); and a hand-DELETE of a + bucket learning records a governance `retire` only when NO layer still holds that id — + the same guard `knowledge purge` already applies to its own cascade. Deleting a throwaway + branch copy is not a retirement of the golden claim of the same name. +- **Read overlay.** Retrieval and the knowledge eval share one overlay + (`overlay.mjs`): golden actives ∪ current-branch bucket actives; a branch-local claim + shadows a same-id golden claim UNLESS the golden claim is protected (≥3 verified + `kind: fix` links or `source: human` — never shadowed; the branch claim renders as an + additional subordinate entry); ids under a standing `retire`/`dispute`/`promote` + decision are never surfaced from a bucket; branch-local wins equal-score ties (layer + tiebreak before the id tiebreak); a bucket whose recorded `baseSha` is not an ancestor + of HEAD (force-push name reuse) is excluded whole. With no `branches/` directory the + read path is byte-identical to the pre-layer behavior. +- **Golden consolidation eligibility (P4).** Once a store has buckets, golden candidacy + requires `branch:` provenance naming the resolved default branch — an episode from an + unpromoted non-default branch, or one with no provenance, routes to branch-local review + and never silently into golden (this is also what a per-layer + `consolidate --rebuild --yes` re-derivation enforces; rebuild wipes each bucket's + learnings/ledger too, keeping `meta.json` as the layer identity). +- **Promotion** (`harness knowledge promote`) emits a reviewable, digest-bound op-set at + `.harness/promote-ops.json` (a contained, atomic `fs-safe` write like every other + workspace write); only `consolidate --apply` in promotion mode applies it. + Promotion ops are exempt from golden candidacy — evidence re-validates from the sha256s + recorded at branch-apply time, never working-tree presence; promotion rejections never + record quarantine strikes; a shadow-of-golden maps to SUPERSEDE (STRENGTHEN when the + overlap is episodes-only); a protected golden target rejects and is marked disputed. + **The ops file is a plain JSON file anyone can hand-author, and its digest is computed by + whoever wrote it — so every admission gate is re-derived by the SOLE WRITER at write + time, never inherited from the emitter**: the bucket key must be a plain directory name + (one shared `isSafeBucketKey` definition — no separators, `..`, `.`, absolute path, + control character, or `:` drive/ADS shape), the bucket must not be a `detached-*` key, + its recorded base must not be provably non-ancestral to HEAD (re-read from the bucket's + own `meta.json`, never the envelope's copy), and each source must still be an ACTIVE, + unpromoted bucket learning (a fresh golden write carries `superseded_by: null`, so an + ungated promotion would strip a tombstone en route). + **Evidence is copied from the source, never described by the op.** An op selects WHICH + recorded episodes to carry; `kind` and `plan` are taken from the source learning's own + records. Re-labelling a recorded `insight` as `kind: fix` used to be enough to make a + promoted claim read as verified fixes across distinct plans — which is simultaneously + the promotion-eligibility signal and the PROTECTED-target signal — i.e. an insight-only + claim could launder itself into permanently protected golden knowledge. + **A promotion op is bound to its source IDENTITY, not just its evidence.** Promotion + moves a claim between layers; it is not an authoring operation. A promotion op-set may + carry only `ADD`/`STRENGTHEN`/`SUPERSEDE` (an allow-list — `MERGE` consolidates several + claims and tombstones every one of them, which no promotion ever does), the destination — + an ADD/SUPERSEDE's `domain/slug`, a STRENGTHEN's `target` — must equal the cited source + id, EVERY other id the op names (`target`, any `targets[]`) must equal it too, and the + promoted claim's `trigger` and `body` are read from the verified source learning rather + than from the op. Binding the destination alone was not enough: `SUPERSEDE.target` names + a DIFFERENT learning and gets stamped `superseded_by`, so a correctly re-digested op could + promote the authentic source claim while tombstoning unrelated golden knowledge the + operator never chose to touch. Without that binding a hand-authored, correctly-re-digested op + could cite one claim's verified identity (including its `source: human` standing, which + the promoted claim inherits) while writing an entirely different, attacker-authored one, + or graft one claim's verified-fix episodes onto an unrelated golden claim. A + rename/re-slug during promotion would have to be its own explicitly gated operation; it + is never implicit. The tombstone below likewise follows the SOURCE id, so a mis-bound or + refused run can never leave the cited source unconsumed and reusable. + Success tombstones each source `promoted_to_golden:` (a retrieval exclusion alongside + `promoted_to`) and records **`absorb-branch`** in the governance ledger — an AUDIT + action: `readGovernance`'s replay considers only `retire`/`dispute`/`confirm`/`promote`, + so an absorb-branch entry can never become an id's standing decision (regression-pinned: + retire → absorb-branch → rebuild still lands retired). +- **Maintenance is layer-aware (§5a).** Hand edits under `branches//learnings/**` + absorb exactly like golden ones (the bucket key is recorded in the snapshot + frontmatter); `knowledge purge `/`--all` cascade across every layer (`--all` + wipes `branches/` whole), with an id's governance record dropped only once no layer + holds it; commit-mode mirroring stays golden-only — buckets are never mirrored. +- **Lifecycle.** `harness knowledge status` is the read-only layer report (golden + per-domain counts, bucket rows with age/base/promotability/ancestry, recall-index + drift); `harness knowledge prune [--branch ] [--merged] [--stale ]` deletes + buckets — human authority, never mode-gated, one store commit. **Prune previews and + confirms**: the selectors are not occupancy tests (a merged branch, a 30-day-old bucket, + or an explicitly named key can still hold live work), so prune and `knowledge status` + share ONE occupancy predicate. Every run prints a per-bucket preview (`active · + promoted · total`) and any prune that would delete ACTIVE, unpromoted learnings is + refused without `--yes`; a bucket status calls prunable (nothing active) still prunes + unattended. Doctor K5 flags orphan buckets (branch gone locally and on remotes), K6 flags + bucket contents whose `branch:` provenance disagrees with the bucket's meta. Branch + renames auto-migrate a bucket to the new key when exactly one gone-branch, + ancestry-verified candidate exists; anything ambiguous is left for `knowledge status`/K5 + and manual prune. +- **Known gap (deferred, not fixed).** The human register is GOLDEN-ONLY: `harness + learnings`, `harness learnings --why `, and `harness learning + ` all read and write the store root, so a + branch-local learning is invisible to them — `--why` on a bucket id returns nothing and + `learning retire` reports `E_TARGET`. The layer-aware ways to act on bucket content + today are `knowledge status` (see it), `knowledge prune` (delete the bucket), a direct + hand edit in the store (absorbed, and now correctly scoped to its layer), or promotion + (move the claim to golden, where the register applies). Making the register layer-aware + is a larger change than this pass took on. + +Phase 3 (the optional tree-sitter structural index under +`~/.harness/index//structural/`) and Phase 4 (per-check verify severity via +policy v2 and the advisory `structural-expectations` check) are shipped. The structural +index is derived state, never knowledge: it lives outside this store, carries no +governance, and is freely deletable and rebuildable — nothing else on this page applies +to it. + +### `advisory` is not available for a gating verify check (human decision) + +Per-check severity has three values, and they are not three shades of the same thing. +`enforce` fails verification, `warn` degrades a failure to `inconclusive` (still a non-zero +exit under enforce), and `advisory` removes the check from the outcome ENTIRELY — +`resolveOutcome` filters advisory checks out before deciding, so an advisory failure leaves +`outcome: passed` in the evidence artifact that `harness gate` and `harness compound` trust +(`validateEvidence` gates only on `outcome !== 'passed'`). Downgrading a real gate to +advisory therefore does two things at once: it opens the gate on a genuine violation, and +it mints a "verified" fix episode from a run that never verified — evidence that then feeds +promotion eligibility in this store. + +So `advisory` is refused, at policy load, for the built-in gating checks — +`plan-selection`, `plan-schema`, `plan-readiness`, `plan-state`, `phase-tasks`, +`criteria-evidence`, `scope`, `primitive-evidence`, `required-reviews`, `hard-gaps`, +`critical-findings`, `workspace-stability` (`NON_ADVISORY_CHECK_IDS`, `lib/policy.mjs`) — +with an error naming the check and pointing at `warn`. `advisory` remains available for +checks whose built-in DEFAULT is advisory (today only `structural-expectations`). +`warn` remains available for every check. Existing v1 policies are unaffected. + +A project's own named check in `checks.yaml` is still the team's to mark advisory — but +only while no plan gates on it. The moment the ACTIVE PLAN lists a check under +`verification.required` (or maps it under `verification.criteria`), that check is a gate, +and `advisory` would erase its failure from the outcome exactly as above. `loadPolicy` +cannot refuse that at parse time — one policy file serves every plan in the repo and knows +none of them — so the rule is applied where the plan and the policy meet, in +`checkSeverityFor`'s `planGatedIds` argument (`lib/policy.mjs`, called from +`applyCheckSeverities` in `lib/verify.mjs`). + +**Decision — ignore, do not refuse.** The downgrade is dropped for that run and the check +falls back to its built-in default (`enforce` for a named check); the run then reports the +refusal in `refusedSeverityDowngrades` on the result, in the evidence artifact, and as a +`warn`-state `policy` line on the CLI. Throwing instead would abort before any evidence is +written, which fails OPEN for the agent (no artifact to gate on at all); ignoring fails +CLOSED, which is what a gate is for. + +Check findings are also less-trusted DATA, not report text: they carry current-side repo +symbols from a lexical extractor with no length bound of its own — and plan-declared +expectations echoed back verbatim — and the CANONICAL `result.checks` array is what +`.harness/evidence/*.json`, `verify --json`, and the event log all serialize. So the +sanitizer runs on that array, at `finalize`, not only on the advisory summary copy: every +string reachable in a check's `message`, `findings`, or `informational` payload is +secret-redacted, flattened to one line, and capped (240 chars per string, 20 entries per +list, 50 findings). A check's `id`, `status`, `severity`, and numeric fields are code-set +tokens and pass through; `stdout`/`stderr` are the trusted named command's own output, +already bounded by `trimOutput` and deliberately left multi-line so a failing check stays +readable. + ## Related - [`.github/skills/references/harness-tool-contract.md`](../.github/skills/references/harness-tool-contract.md) diff --git a/docs/architecture/engineer-harness.md b/docs/architecture/engineer-harness.md index 3e607856..5dc70073 100644 --- a/docs/architecture/engineer-harness.md +++ b/docs/architecture/engineer-harness.md @@ -223,5 +223,6 @@ The verification suite checks the thin Engineer contract, plan and policy schema - [Capability Registry](../../knowledge/capability-registry.yaml) - [Install Guide](../install.md) - [Harness Quickstart](../onboarding/harness-quickstart.md) +- [Harness Evolution Blueprint](../../knowledge/proposals/harness-evolution-blueprint.md) (approved design — phases 1–4 shipped; conditions in its Human Decision remain binding) Historical proposals, comparative reviews, and implementation roadmaps are removed from active documentation after implementation.

Blueprint P1/P9 add optional, reader-tolerant `commit:`/`branch:`/`base:` frontmatter — and require both serializers to *emit* them, because `serializeLearning` (`packages/harness/lib/knowledge/store.mjs`) and `renderLearning` (`packages/harness/lib/knowledge/apply.mjs`) build fixed field lists that silently drop unknown keys on any re-render (STRENGTHEN, absorb, purge delink). +- `EVENT_TYPES` (`packages/harness/lib/events.mjs`) silently drops `init_repo`/`recall`/`validate_plan`/`index` writes — a latent bug footnoted in `harness-tool-contract.md`. `knowledge`-type events already flow, so this is hygiene, not a dependency. +- The layered read path must ship with its safety gates from day one (blueprint §4, approval condition): a branch-local claim never shadows a *protected* golden claim (≥3 verified fixes or `source: human`), and the governance ledger binds both layers — an id under standing `retire`/`dispute`/`promote` is never surfaced from a bucket. +- Provenance strings (branch names, worktree paths) are attacker-influenced on fork checkouts: every rendering passes `inertLine` with a length cap, including the context-pack header (blueprint P9). +- Phase boundaries: bucket *writes*, promotion, prune, doctor K5/K6, and the §5a maintenance-path work are Phase 2 (see `docs/plans/harness-evolution-phase-drafts.md`).

Overlay and ranking semantics + +1. Candidate set = golden actives ∪ current branch-local actives. +2. **Shadowing (gated):** a branch-local learning with the same id replaces the golden + claim in the candidate set, **unless the golden claim is protected** (≥3 verified + fixes or `source: human`) — a protected claim is never shadowed; the branch-local + claim renders as an additional, subordinate entry instead. The pack renders a + `[branch-local]` / shadow marker either way. This mirrors the write-path + protected-target rule so the read path cannot bypass a gate the writer enforces. +3. **Governance binds both layers:** the overlay consults `readGovernance` per id — an + id under a standing `retire`/`dispute`/`promote` decision is never surfaced from a + branch bucket. Reusing a governed id in a bucket triggers the standing decision, it + does not escape it. +4. Ranking uses existing `scoreLearning`; branch-local wins equal-score ties (the layer + tiebreak applies before the id tiebreak, since shadowed ids are identical). Top-3 and + 2048-byte pack caps unchanged. +5. Branch-local claims stay inside the existing untrusted-memory advisory framing; only + an extra marker is added. +6. No branch bucket → golden + one-line drift advisory from `index-status.mjs`. + +## 5. Promotion and pruning contract + +- `knowledge promote` emits a reviewable op-set (`ADD` / `STRENGTHEN` / `SUPERSEDE`) + applied **only** through `consolidate --apply` running in an explicit **promotion + lane**. The lane exists because the standard candidacy gate would otherwise reject + every promotion: branch-local episodes are already consumed in the bucket's own + `consolidated.jsonl`, and their files live on the source branch. Normatively: + - Each bucket carries its own `consolidated.jsonl`; branch consolidation consumes + episodes per-bucket, golden consolidation consumes them in the golden ledger. + - Promotion ops are exempt from the golden candidacy check — their evidence was + disk-verified (sha256) at branch-apply time and is re-validated from the recorded + hashes, not from working-tree presence. + - Promotion rejections **never record quarantine strikes**; promotion is a distinct + rejection class, not a content failure of the underlying episodes. + - All other writer rules bind unchanged: byte cap, secret scan, imperative lint, and + the protected-target dispute rule. + - `promote --all` respects `MAX_OPS_PER_RUN` by chunking: deterministic ordering is + the cursor (as in `consolidate --candidates`), and the command reports + `remaining: N` until the bucket is drained. +- **Shadowed-claim promotion rule:** because golden is the authoritative baseline and a + feature branch is assumed to start from latest main, a branch-local claim that shadows + a golden claim is mapped to `SUPERSEDE` (or `STRENGTHEN` when appropriate). The + promoted claim carries the branch-local evidence as the new authoritative version. If + the golden claim is protected (≥3 verified fixes or `source: human`), the promotion is + rejected and the golden claim is marked disputed for human review — exactly as any + other SUPERSEDE of a protected target. +- **Ledger action:** branch→golden promotion records **`absorb-branch`** (never the + sticky `promote` action). **Replay rule (normative):** `readGovernance`'s standing- + decision replay considers only the decision set (`retire`, `dispute`, `confirm`, + `promote`); `absorb-branch` entries are recorded for audit but never become the + latest-standing decision for an id. Required regression test: `retire` → + `absorb-branch` → `consolidate --rebuild --yes` still lands `retired`. +- On successful promotion the source branch-local entries are tombstoned + (`promoted_to_golden:`), the tombstone is a retrieval exclusion (added to + `retrievalExclusion` alongside `promoted_to`), and the bucket becomes prunable. +- Pruning is human-authority, never mode-gated, and supports both merged and abandoned + branches. + +### 5a. Layer-aware store maintenance (normative) + +The following maintenance paths are root-anchored to `learnings/` today and MUST become +layer-aware in the phase that ships buckets — each is a data-loss or laundering hazard +otherwise: + +- **Hand-edit absorption** recognizes `branches//learnings/**` paths; a hand edit + in a bucket is snapshotted and absorbed exactly like a golden hand edit, never left + for transaction rollback to destroy. +- **`knowledge purge ` / `purge --all`** cascade across all layers: a purged + episode's branch-local learnings are delinked/removed too, and `purge --all` wipes + `branches/`. Human deletion always wins in every layer. +- **`consolidate --rebuild --yes`** wipes and re-derives **per layer**, routing episodes + by their `branch:` provenance. An episode without provenance in a store that has + `branches/` routes to branch-local review — never silently into golden. Rebuild must + not launder unpromoted branch claims into golden. +- **Commit-mode mirroring** (`knowledge commit repo`) remains golden-only and + branch-oblivious; mirroring buckets is out of scope for Phases 1–4. +- **Store schema version:** `ensureStore` writes a schema marker; an older CLI on a + versioned store refuses with a hint rather than operating layer-blind. + +## 6.

Risks and open questions + +- Store growth from long-lived branch buckets → `knowledge status` always hints; prune + remains explicit human action for both merged and abandoned branches. +- Windows path lengths → 64-char branch-key truncation + existing slug caps; Phase 1 + must include a long-branch Windows-shaped fixture. +- WASM size → initial set limited to TypeScript/JavaScript, Python, Java. +- Store lock contention → one `.lock` now serializes every worktree and branch; + long-running promotion must land cancellation on transaction checkpoint boundaries so + the rollback floor holds. +- Recency-rule evolution using commit ancestry is deliberately deferred to a separate + threat-model review. +- Branch-local governance ledger is omitted in Phase 1–2 (buckets are ephemeral; the + golden ledger binds both layers per §4). + +## 9. Relationship to the CLI workbench (TUI) track + +A parallel evolution track — the harness CLI workbench with a TUI session ledger (command +registry dispatching every command, versioned JSON envelope plus JSONL streaming, +append-only run journal with distinct `cancelled` and `timed-out` outcomes, async runner +with cooperative cancellation, gate-state surfaces) — is planned separately and is not +governed by this blueprint. The two tracks compose, and this blueprint's new surfaces must +not paint the workbench into a corner: + +- Every command proposed here (`knowledge status`/`promote`/`prune`, `index --structural` + and any structural query surface) must be registry-dispatchable and emit the versioned + JSON envelope, with JSONL streaming for long operations (structural indexing, promotion + application), so the TUI renders them without bespoke adapters. +- The generation-context stamp (P9) is the `gen ` identity the TUI shows beside + knowledge and search results — keep it stable, short, and cheap to read. +- The structural index (P3) is the backing store for the workbench's + `search --scope code` symbol hits; expose its query path as a command surface, not only + as orient-internal plumbing, so the TUI can call it directly. +- Long-running operations proposed here must support cooperative cancellation and record + distinct `cancelled` vs `timed-out` outcomes in events, matching the run journal's + status model. +- `knowledge status` output should serve both the workbench's one-line footer summary and + its expanded ledger view: summary scalars first, detail arrays after. +- **Three-audience output contract.** Every command surface proposed here renders one + canonical result three ways, and all three renderings are deterministic CLI work — + never a model pass: + 1. **Human** — the styled ledger (`lib/style.mjs` conventions) for eyes. + 2. **Program/TUI** — the versioned JSON envelope for the workbench and other tooling. + 3. **Agent** — a budgeted text rendering for LLM consumption, following the existing + pattern (2048-byte context pack, 220-token plan slice, bounded `get` excerpts). + Agents consume the budgeted lane, never the JSON envelope: JSON is token-inefficient + and its arrays are unbounded, so envelope output must never enter model context. Agent + renderings inherit the existing hardening and metering — data-not-instructions framing, + `inertLine`, and secret redaction wherever the content is retrieved text, plus measured + bytes so `harness report`'s utilization SLOs see their cost. The structural query's + agent rendering carries a token cap, with the repo map's 1000-token budget as the + precedent. This is what makes the workbench's dual human/LLM promise real: no tokens + are ever spent translating one audience's output into another's. + +Where the workbench track defines its own contracts (registry, envelope schema, run +journal), those contracts govern; this blueprint commits its surfaces only to being +conforming citizens of them. + +## Human Decision + +- **Decision:** Approved +- **Reviewer:** Krish (repo owner) +- **Date:** 2026-08-06 +- **Conditions or required edits:** The §4 protected-shadow and governance-binding gates, + the §5 promotion-lane mechanics and `absorb-branch` replay rule, and the §5a + layer-aware maintenance semantics are binding constraints on every implementation + phase.

It also scanned `lib/knowledge` NON-recursively. +// +// The contract below never looks at a path at all. It is three structural +// rules whose conjunction is exhaustive: +// +// 1. REACHABILITY. In a store-writing module the fs module may be reached in +// exactly ONE way: `import fs from 'node:fs'`. No named import, no +// namespace import, no `node:fs/promises`, no `require`/dynamic `import`, +// no destructuring off `fs`, no computed `fs[...]`, no aliasing the module +// object. This is what makes rule 2's textual scan COMPLETE: after rule 1, +// every raw fs use in the file is literally `fs.`. +// 2. PER-FILE VERB ALLOW-LIST. Every `fs.` must appear in the table +// below for that file. Not a deny-list of dangerous verbs — an allow-list +// of the ones each module is known to need, each justified. A NEW verb in +// an existing module, or ANY verb in a new module, fails until a human +// adds it deliberately. +// 3. SCOPE. `lib/knowledge/**` RECURSIVELY (so a future subdirectory is +// covered), plus every module anywhere under `lib/` that imports +// `store-io.mjs` — i.e. the import-graph definition of "a store-writing +// module", so one living outside lib/knowledge is held to the same rule. + +/** + * Permitted raw-`fs` verbs, per module, keyed by path relative to `lib/`. + * Every entry is a DIRECTORY/PROBE operation on the store tree or a + * WORKSPACE-path operation.
