Expose research provenance and direct documentation fetch (#63)

The test spawned a node child that installed a SIGTERM handler and relied on
a 250ms deadline to fire after it. The deadline timer starts at spawn, so on a
loaded runner node had not yet reached `process.on('SIGTERM')` when the signal
landed: the default disposition killed it outright, the 5s grace-timer
escalation never ran, and the elapsed-time assertion saw 462ms. That failed
the v0.10.0 release job before the publish step.

Use `sh -c 'trap "" TERM; exec sleep 30'` instead. The shell boots in ~1ms
rather than a node runtime's tens of ms, and an ignored signal survives exec
where an installed handler would not, so the sleep holding the group ignores
SIGTERM too. Widen the deadline to 1s as well, so the window the child has to
get there is 4x larger.

+## Keeping prompts true (`ecr ref-check`)
+
+Good reviewer prompts cite real code: "the only session entry point is
+`server/src/session.ts`", "every webhook router must call `sanitizeSecrets`". Then the
+code moves and the prompt keeps citing a path that no longer exists — the reviewer
+reasons from a fiction, on every PR, with nothing to warn you.
+
+`ecr ref-check` makes those citations checkable. Pin each one with a ref, in a comment
+of its own (`<!-- … -->` in Markdown, `//` in JSONC):
+
+```md
+<!-- @ref server/src/session.ts#createSession — the only place a session is minted -->
+<!-- @ref server/src/entities/oauth/ — every provider lives here -->
+<!-- @ref glob:**/*WebhookRouter.ts — the routers this rule is about -->
+```
+
+A target is a file, a `dir/`, `glob:<pattern>`, `file#symbol`, or `doc.md#heading` —
+never a line number, since a line number rots without any signal. Symbol anchors are
+checked by whole-word match, so code moving inside its file is fine and a rename is not.
+
+The check is strict on purpose: a backticked token in `.expo-code-review/` that looks
+like a repo path **must** be a ref, because the stale citations are exactly the ones
+nobody thought to annotate. A token with no extension (`eas-build-worker/terraform`,
+`general-central/{module,production}`, `finops`) counts when it names something that
+exists — so those get pinned too, while `anthropic/claude-opus-5`, shaped the same way,
+stays prose. For a token that only looks like a path, say so once:
+`<!-- @ref-ignore knex.raw() -->`. It also checks what your config already declares —
+`enforceAgents` ids, scope `config` directories, scope path globs.
+
+Refs are repo-root-relative, including in a scope's own setup dir. A scope prompt that
+cites `general-central/module` for `infrastructure/general-central/module` gets told the
+root-relative form to use.
+
+Two run points:
+
+- `ecr ref-check` exits 1 on any problem. Run it in CI or a pre-commit hook.
+- `ecr review` / `ecr ci` run it too, and never fail a PR's checks with it. The comment
+  carries a **Review setup** note instead: refs that no longer resolve, plus cited code
+  *this PR* changes, where the ref still resolves but the guidance may not.
+

+
+## Providing context and research capabilities
+
+`@expo/code-review-cli` includes `review-research-mcp` and exposes that one bundled,
+local MCP directly to reviewer and cross-file passes. The agent decides whether an
+external API contract needs research and can either search for an exact symbol or
+fetch an exact supported documentation URL already present in the review context.
+Coordinator, verifier, stack-verifier, and time-critical no-tools passes never receive
+the MCP.
+
+Enable it only in the root config, which CI loads from the PR's trusted base:
+
+```jsonc
+{
+  "research": {
+    "enabled": true,
+    "maxQueries": 8,
+    "resultsPerQuery": 2,
+    "timeoutMs": 15000
+  }
+}
+```
+
+Add a repository Actions secret named `BRAVE_SEARCH_API_KEY`. The generated
+automatic and command-triggered workflows pass only that search credential to the
+MCP. Expo uses its public documentation search and OkHttp uses its official static
+search index; neither consumes Brave quota.
+
+ECR resolves the MCP entry point inside its own installed package and starts it with
+the current absolute Node executable, so a PR-owned `PATH` entry cannot replace
+either component. Each review gets an owner-only temporary MCP config and append-only
+audit. Claude receives that explicit config under `--strict-mcp-config`, with project
+settings and slash commands disabled; OpenCode receives the same fixed local command.
+The Brave credential is passed to the MCP child, not the model process.
+
+The MCP is the outbound security boundary. Search queries are normalized before
+logging or networking: quoted literals, URLs, email addresses, paths, prose stop
+words, overlong/high-entropy tokens, and unsupported punctuation are removed;
+credential-shaped or secret-labeled input fails closed. The remaining query must be
+at most eight short tokens and contain an API-like symbol. Direct URLs must use plain
+HTTPS with no credentials, port, query string, or fragment; suspicious/high-entropy
+path segments fail closed. The fixed provider host/path allowlist and redirect,
+response-size, content-type, and timeout checks still apply after that first gate.
+These deterministic checks greatly reduce accidental exfiltration; they are not a
+proof that every low-entropy string is harmless, so reviewer prompts also forbid
+sending repository text and the review-wide MCP budget defaults to eight calls.
+
+For non-Expo providers, discovery sends a fixed, provider-owned `site:` scope plus
+the bounded query to Brave's fixed Web Search endpoint. Search snippets and titles
+are never treated as evidence. ECR independently rejects off-allowlist result URLs,
+manually validates every redirect, fetches a few official pages, verifies content
+types and response sizes, extracts visible documentation text, and returns locally
+ranked bounded passages. Sparse search-engine coverage therefore produces an honest
+empty result rather than a loose guess.
+
+Research is root-only in routed monorepos because it starts a host process; scope
+configs cannot alter its network behavior or limits. Result-cache reuse remains
+disabled while research is enabled because web results and documentation can change
+without a config change.
+
+The fixed provider catalog covers Apple/Android APIs plus Media3, Glide, OkHttp,
+Kotlin coroutines, Gradle/AGP, Swift concurrency/evolution, platform release/API
+availability, Expo, React Native, Reanimated, Gesture Handler, Screens, and Worklets.
+Queries are short exact symbols plus at most one useful member or behavior term. For
+example, `CameraView barcodeScannerSettings` is useful; a source snippet, import path,
+or natural-language question is not. The MCP publishes the same guidance in its tool
+metadata. An empty result stays empty; it is not replaced with a loose semantic guess.
+
+Direct clients can also call `fetch_platform_doc` with an exact documentation URL.
+The tool infers the narrowest matching provider (or accepts an explicit provider
+hint), then applies the same fixed HTTPS host/path allowlist, manual redirect checks,
+10-second timeout, 5 MB response limit, content-type validation, extraction, and
+passage bounds as search-discovered pages. An optional `query` ranks passages only
+within that one page; it never broadens discovery. For example,
+`https://developer.apple.com/documentation/swiftui/view/menustyle(_:)` is resolved to
+Apple's DocC JSON and returned with the canonical page URL and API availability.
+
+Every research-enabled review audits each sanitized outbound query and each returned result's
+title, provider, provenance class, and canonical URL. GitHub Actions receives the
+same audit trail in the step summary, while `.runs/reviews.jsonl` keeps the queries
+plus bounded returned passages for short-lived operational inspection. Reviewers
+are instructed to attach `sources` only when documentation materially supports a
+finding. ECR accepts only exact URLs returned during that review, restores canonical
+titles, carries citations through coordination, and renders them below the finding;
+invented or unrelated citations are dropped.
+
+For a query routed to the `expo` provider, `serve` POSTs the already-sanitized query
+directly to Expo's public Algolia search endpoint and returns canonical
+`docs.expo.dev` hits. The endpoint, application id, and browser-visible search-only
+key are fixed in the package; redirects are rejected; response size, timeout, hit
+count, and returned URL host are bounded.
+
+OkHttp's newly migrated documentation is still sparse in Brave, so its provider
+downloads the fixed official `lysine.dev` static search index, validates and indexes
+it in memory once per MCP process, and rejects any entry outside the existing OkHttp

+An absolute `research.indexPath` remains available as an optional local fallback.
+The MCP and its trusted updater ship with ECR: build that fallback from this
+repository with `bun run research:update`, or from an installed package with

+step to run before each review. The built-in seed catalog lives in
+`research/sources.json`; `seedUrls` are deterministic starting pages for the
+bounded crawler, and extraction/indexing use no LLM. Installations requiring a fully
+offline review can supply a separately built, verified index and omit the Brave key.
+Installation-specific provider configuration is intentionally
+deferred: when added, it should follow the trusted root-config model used for agents
+without permitting PR-controlled URLs, commands, or executable parsers. Expo skills
+are complementary, not another search corpus: their pinned procedural guidance can
+later be supplied to review agents as separately labeled trusted context, while

+
+A PR author's reply to a finding is matched to it deterministically — by quoting
+the finding's title back, or by citing its short `` `id:…` `` token (only the id can
+clear a finding, see below) — and recorded
+in the comment's embedded state, no model involved in the matching itself. A
+matched finding shows `💬 @login replied` (linked to the comment) and a visible
+count above the fold; the reply's own text is never stored or rendered, only the
+login, the comment link, and (optionally) an enum-valued verdict. Controlled by
+the root-only `feedback` block in `config.jsonc`:
+
+```jsonc
+"feedback": {
+  "mode": "annotate",       // "off" | "annotate" | "adjudicate"
+  "match": "both",          // "quote" | "id" | "both"
+  "dismiss": "never",       // "never" | "maintainers" | "adjudicated"
+  "protectedCategories": ["secrets", "security"],
+  "maxAdjudications": 10    // cap on model calls per run, when mode is "adjudicate"
+}
+```
+
+- **`annotate`** (the default) matches and shows "author replied" with zero effect
+  on the decision — safe and useful even if you never touch this block.
+- **Clearing a finding always needs the `` `id:…` `` token**, in the replier's own words
+  (an id inside a `>` quote does not count). Quoting the title is enough to *annotate*,
+  never to clear: GitHub's "Quote reply" copies the PR author's text verbatim, so a
+  maintainer clicking it would otherwise dismiss a finding on words the author wrote —
+  by accident, or because they were led to.
+- **`adjudicate`** additionally has a model re-check the reply against the actual
+  source (distrust-by-default, like the finding verifier) and record a verdict.
+  Whether that verdict can actually clear a finding is a separate, still-off-by-
+  default choice — `mode` and `dismiss` are independent axes: `dismiss:
+  "maintainers"` lets a maintainer's own reply dismiss with no model involved
+  (it works under plain `annotate` too); `dismiss: "adjudicated"` additionally
+  accepts an author reply the model confirmed (which does need `mode:
+  "adjudicate"` for verdicts to exist). Either way the reply has to cite the finding's
+  `` `id:…` ``. A `critical` finding, or one categorized `secrets`/
+  `security`, can never be cleared this way, whatever the config — that floor is
+  enforced in code, not the prompt.
+- **`/undismiss <id>` wins over a reply.** Running it on a finding a reply cleared
+  puts the finding back in the active list and keeps it there: another reply from
+  the PR author can't clear it again. The restore is recorded against the FINDING
+  in the comment state, not against the reply, so editing or deleting the reply
+  doesn't drop it either. Only a maintainer lifts that — either `/dismiss <id>` on
+  the same finding, or a maintainer's own reply to it.
+
+`ecr feedback` mines this substrate retroactively, with no model call and no
+re-review: it crawls a repo's PRs, reads each one's existing reviewer comment
+(which already embeds its findings), matches non-bot replies against it, and
+reports totals, a reply-rate, breakdowns by category/severity/agent, and — the
+highest-value part — "repeat offenders": findings whose title recurred across 2+
+PRs and drew a reply every single time.
+
+```bash
+ecr feedback --repo your-org/your-repo --limit 100 --since 2026-06-01
+ecr feedback --as my-review-bot   # if CI posts under a PAT/app identity
+ecr feedback --json               # for scripting
+```
+
+The crawl matches the reviewer's comments by author. CI posts them as
+`github-actions[bot]` (the default), so a locally-run crawl uses that identity —
+pass `--as <login>` when your workflow posts under something else.
+
+`ecr feedback` always reads `.expo-code-review/config.jsonc` from the LOCAL
+checkout, even with `--repo`. If `--repo` points at a different repo, it warns
+that `commentTag` may not match, so a zero-findings result there is not read as
+zero pushback. It also warns when every scanned PR had no bot comment at all,
+instead of leaving that as an easy-to-miss "0 with a bot comment" in the totals.
+
+See [LLP 0011](./llp/0011-author-feedback.explainer.md) for why matching is
+deterministic, why reply text is never echoed into the comment, and why the
+defaults are asymmetric.

 `writeRunLog()` (`src/core/log.ts`) appends one JSON line per run — cost, tokens (run-wide and per bucket), findings, coverage notes, decision — so runs are auditable and cost/latency measurable later. The record deliberately excludes PR title and body text, keeping only `baseRef`/`headRef`, to avoid persisting secrets that might appear in author-controlled text [observed] (`log.ts:13-18`). Findings may quote changed source lines, but only content the review already publishes verbatim in the PR comment.
 
+Each successful reviewer pass may also return a bounded conclusion-only trace: up to three concrete checks and two unresolved questions, with each note capped at 240 characters. Trace parsing is deliberately fail-soft: malformed optional diagnostics are dropped while valid findings from the same response survive, so observability can never create a coverage gap. `runReview()` merges and de-duplicates valid notes per reviewer, sorts reviewer ids, caps both the stored roster and the complete decoded trace (6 KB), labels the result `unverified-model-diagnostics`, and attaches it to `CoordinatorOutput.reviewTrace` only after the decision pipeline finishes. `attachReviewTrace` strips any coordinator-authored value before attaching the engine-built trace; even a malformed injected coordinator value parses as absent rather than failing consolidation. The trace therefore never reaches coordination, verification, suppression, or decision logic. Because the GitHub comment already embeds the full coordinator output as durable state, downstream agents can recover the trace without adding visible review prose or storing raw transcripts and chain-of-thought. The same trace rides the run log for short-lived operational inspection [observed: `schema.ts` `ReviewerTraceNotesSchema`/`ReviewTraceSchema`/`ReviewerOutputSchema`; `review.ts` `mergeTraceNotes`/`buildReviewTrace`/`attachReviewTrace`; `render.ts` embeds the full review].

 Observability must never break a review, so both output sinks swallow their own errors: `safeLog` wraps `writeRunLog` and discards any write error [observed] (`review.ts:1269-1275`), and `appendStepSummary` is a no-op outside Actions and swallows append failures [observed] (`step-summary.ts:9-19`). A consequence worth stating: a missing or corrupt run-log entry is therefore **not** an error signal — the log's presence or absence proves nothing about whether the review succeeded.
 
 Finally, `publicFailureReason()` (`src/core/util.ts`) is the only failure text allowed into PR-facing comments [observed] (`util.ts:20-27`; used in `src/commands/ci.ts:176,365,575`). `run()` throws errors of the form `"Command failed: <cmd> <argv>\n<stderr>"`, which embed a subprocess's full command line, its stderr, and absolute runner paths — CI-internal detail of no use to a PR author and exactly what must not leak into an attacker-visible artifact. Those shapes collapse to a generic pointer at the workflow log; the tool's own argv/path-free messages pass through, since they are the actionable ones the fail-fast design means to surface. Every call site still writes the full reason to the job's stderr.

+the progress or error logs because model output is untrusted and may contain source
+secrets or terminal/log-injection payloads. If a stream ends without a final result,
+or its error result has no explicit message, parsing returns a fixed diagnostic rather
+than falling back to the raw JSONL transcript. The fixed diagnostic carries the child
+exit code and may derive an actionable, fixed category from stderr only when no stream
+was emitted (rejected flags, authentication, or launch failure); arbitrary stderr is

+provider-error classification. Every task-specific progress line is tagged with the

There is no side-channel database; the comment body is the state. Dismissed findings render in a collapsed `<details>` section, disjoint from the active list (a finding is never in both), keeping the main list clean while preserving a `by`/`reason` audit trail.
 
+The full review may contain an engine-owned `reviewTrace`. It is deliberately invisible Markdown state for machine consumers, not a human-facing finding or hidden chain-of-thought. Its schema caps both item count and length, and marks every note as `unverified-model-diagnostics`. Keeping it inside `review` rather than beside it is load-bearing: dismissal re-renders already pass `state.review` back through `renderMarkdown`, so the trace survives `/dismiss` and `/undismiss` without another reporter parameter or a second persistence path [observed: `schema.ts` `CoordinatorOutputSchema.reviewTrace`; `reporters/github.ts` `applyDismissal`; `render.ts` `renderMarkdown`].
+
+## Review Result Cache
+
+The same durable comment state is the cache for automated CI reviews. `reviewInputHash` (`src/core/review-cache.ts`) hashes each scoped changed file's content from the materialized PR-head tree, a normalized patch (blob ids and hunk coordinates removed; deletion/mode information retained), and every stable input that can change the result: the engine package version, resolved prompts/config/models, PR title/body, selected agents and routing mode, and external context. It deliberately excludes the temporary trusted-config path and the base/head commit OIDs. A restack changes OIDs and may move hunk line numbers; if it leaves the actual review input byte-identical, CI reuses the complete `CoordinatorOutput` already embedded in the most recent author-verified reviewer comment instead of launching the agents again. Symlinks are hashed as link targets and never followed. A package release changes the key so upgraded review logic runs once. Legacy comments store one `inputHash`; aggregate comments store one per `ScopeReviewResult`, so an unchanged scope can hit independently while a changed sibling reruns.
+
+Reuse is conservative. Manual `/review`/`--force` always reruns. Partial or failed reviews (`incomplete` or `couldNotComplete`) are never cacheable. Aggregate truncation removes the affected scope's hash because the embedded scope is no longer the full result. Stack-aware requalification and model-backed author-feedback seams stay fresh because their live GitHub inputs are not yet represented in the key. Cache lookup failures degrade to an ordinary fresh review. These gates make a false miss cost tokens, while preventing a false hit from presenting stale or incomplete coverage as current.
+
+The hash is state, not display: it lives only inside the base64 state marker and survives `/dismiss`/`/undismiss` re-renders. The existing author-plus-marker ownership check remains the trust boundary for adopting prior state; a PR author cannot forge a look-alike comment and supply a cache entry.
+
 **The coverage note only cries wolf when there is a wolf.** The partial-coverage warning renders only when `review.incomplete` is non-empty (`render.ts:166`) — the aggregate renderer additionally triggers it when unmatched files exist (`render.ts:373`) — a deliberate anti-noise choice so the warning is trustworthy when it appears (`render.test.ts:34`). The advisory footer ("never blocks a merge and never auto-approves") is duplicated verbatim across both renderers because it is a required trust-boundary claim, not incidental text.

+
+A PR author who disagrees with a finding today has one option: reply in prose and
+hope a human reviewer notices. The reviewer itself never reads that reply — every
+run is stateless, so the same finding comes back on the next push even after the
+author explained why it doesn't apply. This feature closes that loop without
+opening the two doors a feedback loop usually opens: letting attacker-controlled
+reply text back into the trusted comment body, and letting a model's opinion of a
+rebuttal outrank the actual code. The shape is: match a reply to the finding it
+answers **deterministically** (no model in the loop), record only enum-valued
+facts about the match, optionally have a model **check the rebuttal against the
+source** (never weigh it as an argument), and apply hard, code-level floors so a
+`critical`/`secrets`/`security` finding can never be talked away. `ecr feedback`
+mines this same substrate retroactively across a repo's PR history, because the
+bot's own past comments already embed their findings.
+
+## Deterministic Matching
+
+A reply is matched to a finding the same way a human would recognize it: by
+quoting the finding's title back, or by citing its short `id:` token — never by
+a model's guess at "which finding is this about." `matchReplies` in
+`src/core/responses.ts` is pure (no IO, no `gh`, no model) so every rule below is
+directly unit-testable [observed] ([responses.ts](../src/core/responses.ts)
+`matchReplies`). `normalizeTitle` strips link targets, emphasis marks, and
+trailing punctuation before comparing, since a reply quoting a rendered title is
+otherwise byte-identical to it [observed] ([responses.ts](../src/core/responses.ts)
+`normalizeTitle`). Quoted lines come only from real blockquotes (`>`), and a `>`
+inside a fenced code block is explicitly skipped — a pasted snippet that happens
+to contain a `>` must never be read as the author quoting the review
+[observed] ([responses.ts](../src/core/responses.ts) `extractQuotedLines`).
+
+Matching is not consent, though: what a match records and what may CLEAR a finding are
+two different questions, and the section "A Quote Annotates, an Id Clears" below is why.
+
+The one rule that matters most: **an ambiguous quote records nothing.** When a
+quoted line's normalized text matches 2+ findings, the match is dropped for that
+line unless the same comment also carries an `id:<fp>` token that disambiguates
+it — because attributing a rebuttal to the wrong finding is worse than recording
+no rebuttal at all [observed] ([responses.ts](../src/core/responses.ts)
+`matchReplies`, the `candidates?.length === 1` gate). A quote shorter than 8
+normalized characters is ignored outright, so a bare `> ok` or `> +1` can never
+collide with a short title [observed] ([responses.ts](../src/core/responses.ts)
+`MIN_QUOTE_LEN`). When several comments answer the same finding, the newest
+(highest comment id) wins — a later reply supersedes an earlier one on the same
+point [observed] ([responses.ts](../src/core/responses.ts) `matchReplies`,
+`newest` map). And a comment carrying the reviewer's own embedded-state marker
+is never treated as a reply, closing the trivial case of the review answering
+itself [observed] ([responses.ts](../src/core/responses.ts) `OWN_COMMENT_RE`).
+
+The reporter feeds this matcher only genuinely human comments — excluded by the
+unspoofable comment author (`user.login`), not by the marker string alone, plus
+a marker check as a second gate — so the same identity discipline that protects
+dismissal state (see [LLP 0008](./0008-sources-and-reporters.explainer.md)
+"github-reporter-identity") protects feedback matching too
+[observed] ([github.ts](../src/reporters/github.ts) `replyComments`). Because the
+matcher never depends on a live run, `ecr feedback` reuses it unchanged to mine
+history: a past PR's bot comment already embeds the findings it surfaced, so
+matching replies against that embedded set needs no re-review and no model call
+[observed] ([feedback.ts](../src/commands/feedback.ts) module header comment;
+`GitHubReporter.collectFeedback`).
+
+## Never Echo Reply Text
+
+`FeedbackRecordSchema` has no free-text field — deliberately. It stores only the
+fingerprint it answers, the replying login, the comment id/url, a `maintainer`
+flag, and two closed enums (`verdict`, `reason`) [observed]
+([schema.ts](../src/core/schema.ts) `FeedbackRecordSchema`). The reply's actual
+words are never written to that record and never rendered: the comment body
+shows only `@login replied` (or the literal `an author` when the login isn't
+GitHub-shaped) linked to the comment, nothing more
+[observed] ([render.ts](../src/core/render.ts) `replyAuthor`, `replyAnnotation`).
+The one place reply text is even read is transient: `adjudicateFeedback` builds
+it into a single model prompt and discards it once that call returns — the
+returned `FeedbackRecord` carries no trace of it
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `AdjudicationItem`,
+doc comment on `replyText`).
+
+This isn't caution for its own sake — it is the fix for a real hole, explained
+next.

+`parseReviewState` and `parseEmbeddedFingerprints` each match the body with a
+**non-global** regex, so they return the FIRST `<!-- tag:state=… -->` /
+`<!-- tag:fingerprints=… -->` marker in the body — while the genuine marker the
+reporter writes is always appended LAST [observed]
+([render.ts](../src/core/render.ts) `parseReviewState`,
+`parseEmbeddedFingerprints`; both call `body.match(...)` with no `g` flag). Any
+externally-sourced string rendered into the body earlier than that trailing
+marker — a model-written `rationale`, a dismissal `reason`, a reply's login —
+could therefore contain a forged look-alike comment that the parser would read
+as the REAL state, letting a PR author dictate their own `dismissed`/`feedback`
+list. This was already a latent hole before this feature (a prompt-injected
+finding field could reach the body); echoing reply text back would have widened
+it, since a reply is attacker-controlled prose by construction.
+
+The fix applies everywhere, not just to feedback: `stripStateMarkers` escapes
+every `<!--` in untrusted prose to `&lt;!--`, so no externally-sourced string can
+open an HTML comment at all — a finding never legitimately needs one
+[observed] ([render.ts](../src/core/render.ts) `stripStateMarkers`). It runs over
+every field that reaches the body from outside the engine: finding `title`,
+`rationale`, `suggestion`, `requalifiedBy.reason`/`.file`, dismissal `by`/
+`reason`, file paths (`locationText`), scope names, and feedback logins/reasons
+[observed] ([render.ts](../src/core/render.ts) call sites in `renderMarkdown`,
+`renderAggregateMarkdown`, `location`, `droppedSuffix`, `addressedLines`). It
+deliberately does **not** touch `evidence` — that field is never rendered into
+the body at all (only quote-grounded against the file during verification), so
+sanitizing it would be dead code masquerading as a guard
+[observed] ([schema.ts](../src/core/schema.ts) `FindingSchema.evidence`
+doc comment; no `finding.evidence` reference exists in `render.ts`).
+
+## Attribution and Identity
+
+Findings gain an optional `agent: string` — which reviewer agent produced
+them — populated by the engine after coordination, never by the model itself
+[observed] ([schema.ts](../src/core/schema.ts) `FindingSchema.agent`). "Never by the
+model" is enforced at the parse boundary, not by convention: `agent` is a RECOGNIZED key
+of `FindingSchema`, so zod's strip could not drop it and a reviewer pass — or the
+coordinator, which reads the untrusted diff and PR body — could emit `"agent": "…"` and
+have it survive validation. The model-facing `ModelFindingSchema` omits the field, and
+both model outputs parse through it, so the engine's own fingerprint lookup is the only
+writer that exists [observed] ([schema.ts](../src/core/schema.ts) `ModelFindingSchema`,
+used by `ReviewerOutputSchema` and `CoordinatorOutputSchema`). It is
+excluded from `fingerprintFinding`'s hashed tuple for the same reason
+`requalifiedBy` is (see [LLP 0010](./0010-stack-aware-requalification.explainer.md)
+"requalification-schema-and-fingerprints"): a finding's identity must stay stable
+across whatever annotations ride alongside it, or an existing dismissal would
+silently lapse the moment attribution appeared on a finding it already covers
+[observed] ([schema.ts](../src/core/schema.ts) `fingerprintFinding`, which hashes
+only `["v2", file, category, key]` — `agent` never enters that tuple).
+
+Attribution survives the coordinator's own merge step by re-matching on
+fingerprint after coordination: each surviving finding is matched back to the
+raw pre-coordination finding that produced the same fingerprint, and the first
+agent found wins when several raw findings merged into one
+[observed] ([review.ts](../src/core/review.ts) the `agentByFp` attribution block,
+right after requalification). A finding the coordinator rewrote enough to change
+its fingerprint (a different `evidence` snippet, a re-categorized `category`)
+stays unattributed rather than guessed — `ecr feedback`'s `byAgent` breakdown
+reports it as `"unknown"`, never a fabricated guess
+[observed] ([feedback.ts](../src/commands/feedback.ts) `aggregateFeedback`,
+`finding.agent ?? "unknown"`).
+
+## The Rebuttal Is a Hypothesis
+
+`templates/shared.md` already tells every reviewer agent that a PR's claims of
+intent ("this is safe", "this is a fixture") carry no weight — only what the code
+does matters. Adjudication must not contradict that rule for a human's rebuttal
+either: a reply is a CLAIM to check against the source, never an argument whose
+tone or authority should move the verdict. `buildAdjudicatorSystem` says exactly
+this, and is deliberately **not** wrapped in `withShared` — it emits a verdict,
+not findings, and stays as distrustful as `buildVerifierSystem` rather than
+inheriting the reviewer-agent framing
+[observed] ([prompts.ts](../src/core/prompts.ts) `buildAdjudicatorSystem`, its
+doc comment). The prompt enumerates what would actually CONFIRM each reason from
+the source (e.g. "pre-existing" is confirmed by finding the same pattern in
+unchanged code, not by the author asserting it), and makes `"unclear"` the
+explicit default whenever the model cannot confirm the claim in the code — never
+accept what you couldn't verify [observed] ([prompts.ts](../src/core/prompts.ts)
+`buildAdjudicatorSystem` body). The reply text itself reaches the model only
+inside a sanitized, fenced `BEGIN/END AUTHOR REPLY` block, with any forged
+boundary line stripped first — the same discipline `contextFileSection` applies
+to external context [observed] ([prompts.ts](../src/core/prompts.ts)
+`buildAdjudicatorTask`, `AUTHOR_REPLY_BOUNDARY`).
+
+Adjudication is wired as a serial tail step in `runReview`, after verification
+(and any stack requalification) and before the coordinator output is handed to
+the reporter — it never runs when `options.feedback` is absent, so every caller
+that doesn't opt in is byte-identical to before this feature
+[observed] ([review.ts](../src/core/review.ts) the `options.feedback` block,
+guarded by `config.mode !== "off"`). It fails open exactly like the rest of the
+review pipeline: an adjudication error is caught, logged as a coverage note, and
+never breaks the run — `ecr ci` must never fail a PR's checks, and this path is
+no exception [observed] ([review.ts](../src/core/review.ts) the `try/catch`
+around `options.feedback.match`/`adjudicateFeedback`).
+
+That fail-open contract has a sharp edge in `comment:'single'` mode, where every
+active scope's feedback seam writes into ONE shared aggregate comment: a transient
+GitHub fetch error inside one scope's seam must never be read as "this scope's
+replies are gone," or the aggregate merge would delete that scope's prior reply
+attributions/verdicts with nothing to replace them the moment the API blips. The
+try/catch above is what makes the two cases distinguishable: a seam that ran and
+matched zero replies sets that scope's `review.feedback` to `[]` (truthy, and
+correctly authoritative — the reply really is gone); a seam that threw leaves
+`review.feedback` `undefined` (the catch never sets it). `mergeAggregateFeedback`
+(`src/commands/ci.ts`) checks exactly that per scope before treating a scope's
+fingerprints as "fresh": a scope whose seam failed this run falls back to its
+prior aggregate records untouched, while a sibling scope whose seam succeeded —
+even with zero results — is still fully authoritative for its own fingerprints
+[observed] ([ci.ts](../src/commands/ci.ts) `mergeAggregateFeedback`,
+`seamOkByScope`).
+
+That authoritative set is built by reading fresh records ONLY from `results` —
+this run's freshly-reviewed scopes — never from `finalResults`, the full set the
+aggregate comment renders (fresh scopes plus whatever `mergePartialAggregate`
+carried over from a `--scopes` partial run). A carried-over scope's entry in
+`finalResults` still embeds whatever `review.feedback` array a PAST full run
+wrote for it; reading records back out of that array would resurrect a stale
+per-scope copy over a newer top-level record — most concretely, a human
+`/undismiss` that already overrode the top-level record (pinning the finding, see
+"The Pin Belongs to the Finding") on a fingerprint the carried scope's own
+embedded copy still remembers as applied. `mergeAggregateFeedback` therefore treats
+`finalResults` as read-only for resolving each kept record's CURRENT finding
+(the fingerprint-to-finding lookup for recomputing `applied`), never as a source
+of feedback records itself [observed] ([ci.ts](../src/commands/ci.ts)
+`mergeAggregateFeedback`, the `results.flatMap(scopeFeedbackRecords)` loop).
+This is also why the embedded state never lets a per-scope copy exist to be read
+back in the first place: `renderAggregateMarkdown` strips `feedback` off each
+scope's embedded `review` before writing state, since the top-level `feedback`
+array is the single source of truth and a per-scope duplicate is exactly the
+stale copy this paragraph guards against [observed] ([render.ts](../src/core/render.ts),
+the `stateScopes` map's `_feedback` destructure).
+
+## A Quote Annotates, an Id Clears
+
+Matching a reply by its quoted title is right for ANNOTATING and wrong for CLEARING,
+because the quoted text is not written by the person who posted the comment. GitHub's
+"Quote reply" copies the whole target comment and prefixes every line with `> `, and
+the PR author controls that text. So: the bot posts the review, which makes every
+finding title (and every `id:` token) public; the author writes one of those titles on
+its own line inside an innocent question; a maintainer answers with one click of "Quote
+reply"; the maintainer's comment now holds `> <finding title>`, `extractQuotedLines`
+returns it, `normalizeTitle` makes it equal to the title, and the match is recorded with
+`maintainer: true` — because `replyComments` reads the maintainer flag off
+`author_association`, which is correct and unspoofable, and says nothing about the words
+being the maintainer's own. Under `dismiss: "maintainers"` that used to be enough to
+move the finding into the collapsed Dismissed fold. The same path fired BY ACCIDENT
+whenever a maintainer quote-replied to an author comment that had pasted a finding
+title, and the mirror case exists on the author path too (the author quote-replying to
+someone else's comment).
+
+Hence the split: **a quote-only match may annotate a finding; only a reply that cites
+the finding's `id:<fp>` token may clear one.** `matchReplies` records which of the two
+happened in `citedId` on the record, and `feedbackApplied` returns `false` before either
+clear path when it is not `true` [observed] ([responses.ts](../src/core/responses.ts)
+`matchReplies`, `citedId: cited.has(fp)`; [adjudicate.ts](../src/core/adjudicate.ts)
+`feedbackApplied`, the `record.citedId !== true` guard). Three properties make that
+gate mean something:
+
+- **The id counts only outside a blockquote.** The id is as public as the title, so a
+  planted `> id:abc123` would defeat the gate exactly like a planted title.
+  `extractCitedFindingIds` drops every `>`-prefixed line before scanning, so only an id
+  in the replier's OWN words counts — and one click of "Quote reply" produces nothing
+  but quoted lines [observed] ([responses.ts](../src/core/responses.ts)
+  `extractCitedFindingIds`).
+- **It is derived, never stored-and-trusted.** `citedId` is re-derived from the live
+  comment on every run, the same discipline as `maintainer`/`author`; absent reads as
+  "did not cite", so a record written by an older version (or carried through a failed
+  seam) fails CLOSED to annotate-only until its reply is matched again
+  [observed] ([schema.ts](../src/core/schema.ts) `FeedbackRecordSchema.citedId`,
+  optional).
+- **It is orthogonal to the `match` config.** `match` (`"quote"`/`"id"`/`"both"`)
+  selects how a reply is MATCHED and is unchanged; `citedId` is computed whatever it
+  says, so a repo on `match: "quote"` still annotates every quote and still clears on a
+  cited id [observed] ([responses.ts](../src/core/responses.ts) `matchReplies`, `cited`
+  built outside the `opts.match` branches).
+
+The cap follows the same logic: a quote-only reply cannot clear whatever a verdict says,
+so `adjudicateFeedback` no longer spends a model call on it — judging it would consume
+`maxAdjudications` on an outcome-free rebuttal and could starve one that does cite the
+finding [observed] ([adjudicate.ts](../src/core/adjudicate.ts) `adjudicateFeedback`, the
+`toJudge` filter). The `/undismiss` pin is untouched by all this: a maintainer's newer
+reply still LIFTS a pin without citing anything, because lifting is not clearing — after
+the lift the record still has to cite the id to remove the finding, so the worst a
+quote-reply can do is return the finding to the ordinary rules.
+
+## Hard Floors in Code
+
+The prompt tells the model to be distrustful; the floor that actually protects a
+`critical`/`secrets`/`security` finding lives in TypeScript, not in anything a
+model could be argued out of. `feedbackApplied` is the single function that
+decides whether a reply clears a finding, and it returns `false` unconditionally
+for `finding.severity === "critical"` and for any finding whose category is in
+`HARD_FLOOR_CATEGORIES` (`secrets`, `security`) — a constant the configured
+`protectedCategories` can only ADD to, never shrink, since that check runs
+independently of the floor [observed] ([adjudicate.ts](../src/core/adjudicate.ts)
+`HARD_FLOOR_CATEGORIES`, `hardFloored`, `feedbackApplied`). The floor is also the
+reason such a reply is never JUDGED: `hardFloored` is one function read by both
+`feedbackApplied` and `adjudicateFeedback`'s `toJudge` filter, so the two can never
+drift into a model call whose verdict the floor would then discard — a call that also
+consumed one of the `maxAdjudications` slots a clearable finding's reply could have
+used. The skip is deliberately NOT counted in `skipped`: that figure surfaces as "N
+left unjudged over the cap", and raising the cap would buy back no coverage here,
+so counting it would report a gap that does not exist. The config-tunable exclusions
+(`protectedCategories`, `dismiss`) are deliberately left IN the judged set — they can
+change, and `applied` is recomputed under the current config on every run, so a stored
+verdict there becomes useful the moment a repo widens its policy
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `adjudicateFeedback`, the
+`!hardFloored(item.finding)` term of `toJudge`). Above those floors, dismissal is
+gated by `dismiss` alone: `"never"` (the shipped default) short-circuits to
+`false` before any floor is even checked, so nothing clears a finding until a
+repo explicitly opts in. `mode` is deliberately a separate axis — it selects
+how much machinery runs (off / match-and-annotate / also judge), not who may
+clear — so `dismiss: "maintainers"` works under plain `mode: "annotate"`
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `feedbackApplied`, the
+first guard clause; `feedbackNeedsRunSeam` is what wires the seam for that
+combination). Coupling the two would force a repo to switch on the model mode
+just to enable the no-model maintainer path, which is the same trust gate as
+`/dismiss` in prose form. A maintainer's reply that CITES the finding's id clears it
+with no model involved at all (`record.maintainer` plus `record.citedId`, see "A Quote
+Annotates, an Id Clears"); among everyone else, only the PR
+AUTHOR's cited reply can clear one, and only under `dismiss: "adjudicated"` AND a
+recorded `"accepted"` verdict — never on an `"unclear"` or `"refuted"` one, and
+never for a third-party commenter's reply even when the model accepted it: the
+adjudicated path is the author's alone, so a stranger's rebuttal is annotated
+but can never move the outcome [observed] ([adjudicate.ts](../src/core/adjudicate.ts)
+`feedbackApplied`, the `record.author === true` check on the final branch).
+`record.author` is re-derived every run from the live comment's login against
+the PR's own author login — never trusted from stored state, the same
+unspoofable-identity discipline as `maintainer` — so an unresolved author (a
+`gh pr view` failure) is `undefined`/`false`, which fails CLOSED to "never
+clears" rather than open [observed] ([responses.ts](../src/core/responses.ts)
+`ReplyComment.author`; [github.ts](../src/reporters/github.ts)
+`resolvePrAuthor`, `replyComments`).
+
+Re-deriving it costs a `gh pr view`, and `mode: "annotate"` is the shipped
+default, so that call would otherwise land on EVERY report of every adopting
+repo — multiplied per scope in routed CI, which builds one reporter per scope
+comment plus one for the aggregate comment. Two things bound it, and neither weakens
+the fail-closed rule. The flag gates exactly one branch, so it is resolved only when that
+branch is reachable: `feedbackNeedsPrAuthor` returns true for
+`dismiss: "adjudicated"` and nothing else, and a skipped lookup reads the same
+as a failed one — `author: false`, clears nothing
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `feedbackNeedsPrAuthor`;
+[github.ts](../src/reporters/github.ts) `replyComments`). And when it does run,
+the result is memoized per PR across reporter INSTANCES, not per instance: the
+author's login is a property of the PR, so N scopes share one call. The cache
+holds the in-flight promise (concurrent scopes join it rather than racing) and
+is keyed by checkout + repo + PR number, so a lookup can never leak across the
+many PRs the `ecr feedback` crawl walks in one process
+[observed] ([github.ts](../src/reporters/github.ts) `prAuthorByPr`,
+`prAuthorCacheKey`, `sharedPrAuthor`).
+
+Only a SUCCESSFUL lookup is cached, though. A failed `gh pr view` resolves to
+null — the fail-closed answer for that attempt — and caching that null would turn
+one rate-limited call into a process-wide outcome: the first scope's blip would
+mark every later scope's replies `author: false` and keep the adjudicated clear
+path from firing for the rest of the run, on a PR where the very next attempt
+would have succeeded. Sharing the cache across instances is what made that a
+single point of failure, so `sharedPrAuthor` deletes its entry when the promise
+settles to null (or rejects), leaving neither a poisoned result nor a dangling
+in-flight entry, while the entry is still what concurrent scopes join
+[observed] ([github.ts](../src/reporters/github.ts) `sharedPrAuthor`, the
+`forget` helper).
+
+The other half of that cost is per instance and stays per instance: the paginated
+comment list (a 30s TTL cache) and the resolved bot login. So the rule in `ci.ts` is
+**one reporter per comment, not one per call site** — a scope's feedback seam reads the
+very comment that scope's review is posted to, so a second instance for the same tag
+re-fetches the identical list and re-resolves the login. `comment:'single'` mode shares
+`singleModeReporter` across every scope's seam and the aggregate post; per-scope mode
+memoizes one reporter per scope name and uses it for both that scope's seam and its
+`report()` [observed] ([ci.ts](../src/commands/ci.ts) `singleModeReporter`,
+`memoizeByScope`). The link context the report needs is inert for the seam
+(`matchAdjudicationItems` renders nothing), so one link-carrying reporter serves both.
+
+`adjudicateFeedback` re-derives `applied` for **every** record on every call —
+including ones a model never touched this run (already-decided verdicts from a
+prior run are skipped to avoid re-spending the budget on the same words,
+tracked via `record.verdict === undefined`) — so a config change (e.g. flipping
+`dismiss` from `"adjudicated"` back to `"never"`) takes effect immediately on
+the next run without needing new replies [observed]
+([adjudicate.ts](../src/core/adjudicate.ts) `adjudicateFeedback`, the `records`
+map at the end). The cap (`maxAdjudications`) is enforced by slicing, never by
+silent truncation: everything past the cap is counted in `skipped` and surfaced
+as a coverage note on the review output, and a per-record model error is caught,
+counted in `failed`, and leaves that record unjudged rather than throwing
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `adjudicateFeedback`,
+the `within`/`skipped` slice and the per-item `try/catch`;
+[review.ts](../src/core/review.ts) the `incomplete` push when `skipped > 0 ||
+failed > 0`).
+
+Turning `mode` to `"off"` degrades the same way, on the render side rather than
+the seam side: `GitHubReporter.computeFeedback` recomputes `applied` for every
+carried record under the CURRENT config (so a reply-cleared finding correctly
+falls back to the active list) but keeps the records themselves — who replied,
+any verdict — instead of discarding them, and the pin set rides the state
+untouched beside them. Returning an empty list here instead would silently erase
+every recorded reply from the comment's embedded state the moment a repo flips
+the switch, with no way back; `"off"` must mean "stop matching new replies," not
+"forget the ones already recorded" [observed]
+([github.ts](../src/reporters/github.ts) `computeFeedback`, the
+`!config || config.mode === "off"` branch returning `reapply(previous)`).
+
+`applied` being a function of the current config and not a stored fact has to
+hold on EVERY path that rewrites the comment, including the one that runs no
+review: `/dismiss` and `/undismiss` re-render the whole comment from its embedded
+state, so a record they do not touch used to flow through with whatever `applied`
+the run that stored it computed. A repo that had since tightened `dismiss` back
+to `"never"`, or widened `protectedCategories`, would then keep an unrelated
+finding hidden until the next full review — a maintainer's action on finding A
+freezing the policy on finding B. `applyDismissalToState` therefore maps every
+record through the same `feedbackApplied`, resolving each record's finding by the
+id the comment renders it under (scope-namespaced on an aggregate comment); a
+record whose finding is gone keeps its stored flag, exactly as `computeFeedback`
+does [observed] ([github.ts](../src/reporters/github.ts)
+`applyDismissalToState`, `stateFindingsById`). `ecr dismiss` passes the loaded
+`feedback` block to the reporter for that reason
+[observed] ([dismiss.ts](../src/commands/dismiss.ts)).
+
+## Suppression Is Never Silent
+
+[LLP 0010](./0010-stack-aware-requalification.explainer.md) established the
+rule for stack requalification: an effect on a real finding must never be a
+"collapsed fold nobody reads" — it needs a visible, above-the-fold count.
+Feedback reuses the identical shape. `feedbackAuditNote` renders
+`> 💬 **N finding(s)** have an author response (M applied).` above the finding
+list whenever N > 0, mirroring `requalificationAuditNote` line for line
+[observed] ([render.ts](../src/core/render.ts) `feedbackAuditNote`,
+directly beside `requalificationAuditNote`). An `applied` finding doesn't just
+disappear from the active list either: it moves into the same collapsed
+"Dismissed" section a manual `/dismiss` uses, with its own audit suffix —
+`— dismissed via reply by @login` — so a reply that cleared a finding is
+recorded exactly as auditably as a maintainer's explicit dismissal
+[observed] ([render.ts](../src/core/render.ts) `droppedSuffix`, the `reply`
+branch; `renderMarkdown`'s `isDropped` treats `feedbackByFp.get(fp)?.applied`
+the same as an explicit dismissal). The aggregate renderer applies the same
+note and the same fold, per scope, keyed by the scope-namespaced id so a record
+never crosses scope boundaries [observed] ([render.ts](../src/core/render.ts)
+`renderAggregateMarkdown`, `feedbackById` keyed via `idOf`). That fold opens
+whenever the scope has an active finding, a requalified one, OR a reply that
+suppressed one: a scope whose ONLY findings were cleared by replies (`shown`
+and `requalifiedAll` both empty) still opens with the audit note above the
+fold, never collapsed away as if the scope were silently clean
+[observed] ([render.ts](../src/core/render.ts) `renderAggregateMarkdown`, the
+`open` line's `replies.length > 0` disjunct).
+
+Feedback records — and the `/undismiss` pin set beside them — also ride the
+embedded comment state exactly like dismissals: they are never trimmed away by
+the aggregate's size-based truncation loop, even when that loop is shrinking how
+many findings are shown, because losing one would silently lose a verdict a prior
+run already decided, or a restore no later run could recover
+[observed] ([render.ts](../src/core/render.ts) `renderAggregateMarkdown`, the
+comment above the state marker: "Feedback records and `/undismiss` pins ride the
+state whole, never trimmed by the cap loop"). And the reporter's merge step
+(`mergeFeedback`) only ever carries a decided `verdict`/`reason`/`applied`
+forward when the newest reply on that finding is the SAME comment it was
+decided about — a newer reply resets the decision, because a new reply answers
+different words and deserves its own judgment
+[observed] ([github.ts](../src/reporters/github.ts) `mergeFeedback`, the
+`prior.commentId === record.commentId` gate).
+
+That same-comment gate is necessary but not sufficient. A verdict is a claim
+about SOURCE, not only about words: `fingerprintFinding` deliberately excludes
+the line number, so a finding keeps its identity while the code that justified
+the rebuttal is edited away elsewhere in the file. `dropStaleVerdict` is the one
+predicate that says so: a decided `verdict`/`reason`/`applied` survives only
+while the record's `sourceSha` — the reviewed head OID stamped on it when the
+adjudicator answered — equals the head this run reviews
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `dropStaleVerdict`;
+`adjudicateFeedback`, the `sourceSha` stamp). Unknown source counts as
+different, never as trusted: a run with no head SHA (the `ecr feedback` crawl,
+which reviews nothing, or `local-git`, which resolves no `headOid`) and a record
+written before the field existed both drop the verdict, so a missing SHA can
+never pin a decision forever [observed] ([schema.ts](../src/core/schema.ts)
+`FeedbackRecordSchema.sourceSha`, optional). The dropped record flows back
+through `adjudicateFeedback`'s `toJudge` filter and the reply is judged again
+against the new source; its stale `applied: true` drops with it, so no render
+hides the finding in between.
+
+That predicate is deliberately ONE exported function rather than a rule each
+merge path restates. There are two such paths — `mergeFeedback` in the reporter,
+and `mergeAggregateFeedback` in `ci.ts` for the `comment:'single'` aggregate —
+and they did drift: the aggregate path kept every prior record whose fingerprint
+no fresh scope claimed and only recomputed `applied`, which `feedbackApplied`
+derives without ever looking at `sourceSha`. A scope whose seam threw on run 2
+therefore carried run 1's `"accepted"` verdict onto a head that verdict never
+judged, and because `reportAggregate` skips `computeFeedback` whenever it is
+handed explicit records, nothing downstream re-checked it. Both paths now call
+`dropStaleVerdict` on every record they take from prior state — fresh records
+are exempt, having just been stamped with this run's own source
+[observed] ([ci.ts](../src/commands/ci.ts) `mergeAggregateFeedback`, the
+`dropStaleVerdict` in the `prior` filter; [github.ts](../src/reporters/github.ts)
+`mergeFeedback`).
+
+Two things deliberately survive a head change. A verdict-less record does,
+because a maintainer clears with no model call and no verdict, so it has no
+source-dependent decision to go stale
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `dropStaleVerdict`, the
+`record.verdict === undefined` short-circuit). And a maintainer's `/undismiss`
+pin does — it is not a claim about source at all, which the next section is
+about. The cost is real and bounded: a push that touches nothing relevant
+re-spends adjudication budget re-judging the same words, capped by
+`maxAdjudications`. Paying that beats hiding a finding against source the
+rebuttal no longer fits.
+
+## The Pin Belongs to the Finding
+
+Suppression by reply must be exactly as reversible as suppression by
+`/dismiss`: a maintainer running `/undismiss <id>` on a finding a REPLY cleared
+(not only a manual dismissal) restores it to the active list, not just to the
+Dismissed fold. So `/undismiss` records a **pin** on that finding, and
+`feedbackApplied` checks the pin before any other floor — a later re-review,
+recomputing `applied` from that same still-present reply, must not silently
+re-clear what the human just restored
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `feedbackApplied`, the
+`record.unclearedByHuman` guard; [github.ts](../src/reporters/github.ts)
+`applyDismissalToState`, the `removeSet` branch).
+
+**The pin belongs to the FINDING, not to one reply — so it cannot live on a
+reply record.** It is stored as its own field of the embedded comment state, a
+`pins` set of `{fp, commentId}`, and every render writes that set forward whole:
+not indexed by the records this run matched, not filtered by the findings this
+run emitted, and never trimmed by the aggregate's size cap loop
+[observed] ([render.ts](../src/core/render.ts) `reviewState`, `ReviewState.pins`;
+[schema.ts](../src/core/schema.ts) `FeedbackPinSchema`). `applyPins` stamps the
+set back onto the matched records (`unclearedByHuman: true`, `applied: false`)
+so `feedbackApplied` stays a pure record-local decision, and strips the flag from
+any record the set does not pin — the set decides, the flag is only its shadow
+[observed] ([schema.ts](../src/core/schema.ts) `applyPins`; call sites in
+[github.ts](../src/reporters/github.ts) `computeFeedback`,
+`buildAdjudicationItems`, `report`/`reportAggregate` and in
+[ci.ts](../src/commands/ci.ts) `mergeAggregateFeedback`).
+
+Two rounds of this design got the lifetime wrong, in the same direction both
+times: binding the pin to something the untrusted PR author controls. The first
+bound it to one `commentId`, reasoning that "a newer reply is a fresh decision
+that shouldn't be gagged" — but `matchReplies` keeps only the NEWEST comment per
+finding, so the author had only to post one more comment quoting the same title:
+the fresh record carried a different id, the pin vanished, the reply was judged
+again, and an `"accepted"` verdict removed the finding a maintainer had just
+restored. The second kept the pin on the record while carrying it across a newer
+reply — which closed that path but not the shorter one, because a record exists
+only while some reply still matches the finding. `mergeFeedback` maps over the
+FRESH records, and the render stores only what it returns, so one run with no
+matching reply wrote the pin out of existence: the author edits (or deletes) the
+comment that quoted the finding, pushes, then restores the quote and pushes
+again, and the reply is judged afresh with no pin left to stop it. The aggregate
+path lost it the same way, for every fingerprint a fresh scope claimed. The
+non-attack case is identical and just as bad: a re-review that simply does not
+emit that finding this run would drop a maintainer's restore.
+
+Hence the invariant: **a pin is created and lifted only by a maintainer action,
+and nothing else can touch it.** A `/dismiss` on that finding lifts it —
+`applyDismissalToState` removes the fp from the set, the same trusted hand
+deciding the opposite way. A maintainer's own newer reply lifts it — the same
+trusted hand, and a lift is not a clear: the lifting reply still has to cite the
+finding's id before it removes anything (see "A Quote Annotates, an Id Clears"), so a
+lift only returns the finding to the ordinary rules. "Newer"
+is decided against the comment id stored with the pin, so a maintainer comment
+that predates the restore (one the author could resurrect by deleting their own
+later reply) never releases it
+[observed] ([schema.ts](../src/core/schema.ts) `applyPins`, the
+`record.commentId > (pin.commentId ?? 0)` gate). Everything else — a newer reply
+from the PR author, an edited, deleted or unmatched reply, a moved head, a run
+that re-emits nothing — leaves the pin exactly where it is. A human's override is
+not a claim about one comment's words, nor about one revision; it is a decision
+about that finding. The rebuttal still gets its hearing — from a maintainer, who
+can `/dismiss` or reply themselves.
+
+A pinned finding is also excluded from `adjudicateFeedback`'s model pass — there
+is nothing to gain by re-judging a reply whose verdict, even if `"accepted"`, a
+human has already overridden
+[observed] ([adjudicate.ts](../src/core/adjudicate.ts) `adjudicateFeedback`,
+the `toJudge` filter).
+
+The embedded state is a compatibility surface, so moving the pin needed a
+migration, not a cutover: a comment written before `pins` existed carries its
+pins on the records themselves, and reading it as "no pins" would silently
+release every restore already made. `collectPins` unions the state's set with any
+record-level `unclearedByHuman` flag, and `parseReviewState` runs it on every
+read, so a v3 comment upgrades on its next render
+[observed] ([render.ts](../src/core/render.ts) `parseReviewState`;
+[schema.ts](../src/core/schema.ts) `collectPins`). The flag is still written onto
+the records too — as a derived mirror, never as the storage — so a comment this
+version writes also reads correctly under an older one.
+
+## Asymmetric Defaults
+
+The `feedback` config block ships with `mode: "annotate"` on by default and
+`dismiss: "never"` off by default — an intentionally asymmetric pair
+[observed] ([schema.ts](../src/config/schema.ts) `ReviewConfigSchema.feedback`,
+`.default({...})`). The reason is structural, not cautious-for-its-own-sake:
+adopting repos maintain their own `.expo-code-review/config.jsonc` and never
+re-copy `templates/config.jsonc` wholesale, so a key a repo never touched must
+still resolve — via the zod default, not the template comment — to behavior
+that is both safe and useful. Matching and annotating a reply is safe with zero
+review-outcome effect, so it defaults ON; letting a reply (or a model's read of
+one) actually remove a finding from the blocking set is a real decision a repo
+should make deliberately, so it defaults OFF until a maintainer opts in
+[observed] ([schema.ts](../src/config/schema.ts) the comment directly above
+`feedback:`, and [load.ts](../src/config/load.ts) `FEEDBACK_CONFIG_DEFAULTS`,
+which mirrors the same values for a scope load).
+
+Like `stack` before it ([LLP 0010](./0010-stack-aware-requalification.explainer.md)
+"config-and-cli-surface"), `feedback` is root-only: `ScopeReviewConfigSchema`
+rejects it with a `z.never({...})` whose message names the reason — "the
+comment lifecycle is global" — matching the existing `stack` lock's style
+exactly [observed] ([schema.ts](../src/config/schema.ts)
+`ScopeReviewConfigSchema`, the `feedback: z.never(...)` entry). One PR has one
+comment lifecycle; a scope-level override would be meaningless and a silent
+divergence hazard, the identical argument LLP 0010 makes for `stack`. With no
+`routing.jsonc` at all, or a scope config that simply omits the block,
+`LoadedConfig.feedback` resolves to the same defaults either way — via the root
+schema's zod default in the unrouted case, and via `FEEDBACK_CONFIG_DEFAULTS`
+in the routed scope-load case — so adoption is exactly as incremental as every
+other root-only feature in this engine
+[observed] ([load.ts](../src/config/load.ts), the `feedback: parsed.feedback ??
+FEEDBACK_CONFIG_DEFAULTS` line).
+
+## `ecr feedback`: The Same Substrate, Read Backwards
+
+Everything above exists to answer one question a maintainer actually asks:
+"has this kind of finding been pushed back on before, and how?" `ecr feedback`
+answers it without a single model call, because the answer is already sitting in
+history: every past reviewer comment embeds the findings it surfaced (`state`),
+and `collectFeedback` re-runs the exact same `matchReplies` pass over that
+embedded set plus the PR's non-bot comments — no re-review, no re-diff
+[observed] ([github.ts](../src/reporters/github.ts) `collectFeedback`;
+[feedback.ts](../src/commands/feedback.ts) module header). The one place this
+command departs from fingerprint identity on purpose is its "repeat offenders"
+grouping: a finding's fingerprint legitimately differs across PRs (different
+file, different evidence snippet) even when it is recognizably "the same
+issue" to a human, so offenders are grouped by `normalizeTitle` — the identical
+normalization the matcher itself uses to compare a quote to a title — not by
+fingerprint [observed] ([feedback.ts](../src/commands/feedback.ts)
+`repeatOffenders`, keyed on `normalizeTitle(finding.title)`). An offender only
+qualifies when it recurred across 2+ PRs AND drew a reply on **every** one of
+them, deliberately stricter than "recurred and got at least one reply" — a
+title answered once out of three occurrences is noise, not an established
+pattern worth surfacing [observed] ([feedback.ts](../src/commands/feedback.ts)
+`repeatOffenders`, the `answeredEveryTime` check).
+
+Because the crawl is retroactive and stateless, two failure modes could
+otherwise print identical output to "no pushback ever happened": scanning the
+wrong repo, and a `commentTag`/`--as` mismatch that makes every past comment
+invisible to `readState`/`replyComments`. `--repo` lets a crawl target a repo
+other than the local checkout, but `feedbackCommand` always loads
+`.expo-code-review/config.jsonc` from the LOCAL checkout — it never fetches or
+trusts a remote repo's config, since a repo's own config is untrusted input
+from the reviewed repo's perspective (see [LLP 0001](./0001-trust-model.principles.md)).
+When `--repo` differs from the local checkout's own repo,
+`repoConfigMismatchWarning` prints a warning naming both repos so a
+zero-findings crawl is not mistaken for zero pushback [observed]
+([feedback.ts](../src/commands/feedback.ts) `repoConfigMismatchWarning`,
+`feedbackCommand`). Separately, when every scanned PR came back with no bot
+comment at all, `allNullCrawlWarning` surfaces that as an explicit line in the
+totals section instead of leaving it as an easy-to-miss "0 with a bot comment"
+[observed] ([feedback.ts](../src/commands/feedback.ts) `allNullCrawlWarning`,
+`formatFeedbackReport`). Both are warnings only: neither changes which config
+loads or which PRs get scanned, matching this feature's fail-open-but-visible
+posture throughout.
+
+## What Ships Dark, and Why That's the Point
+
+Every piece of this feature composes to the same conservative shape as the
+config defaults: annotate is real and on, and no reply has any decision effect
+until a maintainer flips `dismiss` off `"never"`. That is deliberate
+sequencing, not caution for caution's sake — the same posture
+[LLP 0010](./0010-stack-aware-requalification.explainer.md) took for stack
+requalification (`enabled: false` by default, "a suppression-adjacent feature
+earns trust with field data first"). A repo gets the useful, zero-risk half
+(a visible "author replied" annotation, and `ecr feedback`'s retroactive report)
+immediately, and the risk-bearing half (a reply actually clearing a finding)
+only behind that one explicit knob — `"maintainers"` needs no model at all,
+`"adjudicated"` additionally requires `mode: "adjudicate"` so an author's reply
+clears only with a source-confirmed verdict — with
+`critical`/`secrets`/`security` never reachable by either choice, and every clear
+requiring the replier to cite the finding's id in their own words.

+# LLP 0012: Review-Setup Ref Integrity
+
+**Type:** Explainer
+**Status:** Active
+**Systems:** Engine, CLI
+**Author:** Philippe Loulidi / Claude
+**Date:** 2026-08-03
+**Related:** [LLP 0006 Config Schema, Loading, and Routing](0006-config-schema-loading-routing.explainer.md), [LLP 0007 CLI Commands and CI](0007-cli-commands-and-ci.explainer.md), [LLP 0009 Adoption Templates and CI Workflows](0009-adoption-templates-and-ci-workflows.guide.md)
+
+A repo's reviewer prompts are full of citations into its own code: "the only session
+entry point is `server/www/src/utils/session.ts`", "every webhook router must call
+`sanitizeSecretPatterns`". Those citations are load-bearing — they are how a prompt
+carries repo knowledge the model does not have — and nothing kept them true. Code
+moves, symbols get renamed, and the prompt keeps citing a path that no longer exists.
+The reviewer then reasons from a fiction, silently, on every PR.
+
+`ecr ref-check` (`src/commands/ref-check.ts`, over `src/core/config-refs.ts`) closes
+that gap: every code citation in a `.expo-code-review/` setup must be a ref, and every
+ref must resolve against the checkout. It is deterministic — no model, no network —
+in the same family as `ecr verify-config` (see [LLP 0007][verify]).
+
+Two measurements motivated the strict form. Swept against a real adopting monorepo
+(universe) the check found 165 citations, none of them annotated or verified by
+anything; swept against this repo's own setup it found 24 [observed]. Not one of those
+citations was checked before this existed.
+
+## The `@ref` Grammar
+
+One grammar, reused from the engine's own LLP annotations, so an author learns it once:
+
+    @ref <target> [relation] — why it matters
+
+In markdown it lives in an HTML comment, in JSONC after `//`. Targets:
+
+| Target | Resolves when |
+|---|---|
+| `path/to/file.ts` | the file exists |
+| `path/to/dir/` | the directory exists (trailing slash is required) |
+| `path/to/file.ts#symbolName` | the file exists and still contains that whole word |
+| `path/to/doc.md#heading` | the file exists and has that heading |
+| `glob:**/Handler.kt` | at least one file in the repo matches |
+| `https://…` | shape only, never fetched |
+
+Refs are **always repo-root-relative**, including inside a scope's setup dir. A scope's
+prompts describe the same tree the reviewer sees in the diff, so a second base
+directory would only create ambiguity about which one a ref meant. Scoped prompts do
+naturally cite their own subtree (`general-central/module` for
+`infrastructure/general-central/module`), so that stays a broken ref — but the message
+resolves it against the scope root and names the root-relative form to use.
+
+`glob:` exists for readability. A Kotlin path 90 characters deep gets abbreviated in
+prose (`.../config/MetricGroupCounter.kt`) and an abbreviation cannot be resolved, so
+the check suggests the suffix glob `glob:**/config/MetricGroupCounter.kt` — short in the
+prompt, still verified.
+
+**Invariant:** a target is data, never a command. Resolution reads files inside the repo
+root only, via the same `pathInside` confinement the verifier uses ([LLP 0005][verify5]);
+absolute paths and `..` escapes are refused, not resolved.
+
+## No Line Numbers, Symbol Anchors Instead
+
+A ref may not pin a line. `src/auth.ts:42` is refused in an annotation *and* in prose,
+because a line number is the one form of citation that rots without any signal: insert
+a line above it and the ref still "resolves", now pointing at unrelated code. `#symbol`
+is the robust alternative — it survives the code moving inside its file, and breaks
+exactly when the thing cited is renamed or deleted, which is when a human should look.
+
+For the same reason there is no content hash or pinned revision in the grammar. A digest
+would trip on every edit to the cited file, including edits that leave the prompt
+perfectly correct, and a check that cries wolf gets disabled. The drift signal lives on
+the review side instead (below).
+
+## Unannotated Citations Are Broken Refs
+
+Checking only what an author annotated would make the mechanism decorative: the stale
+citations are precisely the ones nobody thought about. So a backticked token in a setup
+file that *looks like* a repo path and is not a ref fails the check.
+
+That rule needs a precise notion of "looks like a path", because prompts also backtick
+config keys, severities, commands and model ids. It comes in two tiers.
+
+**Shape alone** (`isCodeCitation`): an allowlisted source extension, a trailing slash, or
+a wildcard tail inside a path — and never whitespace, `:`, `<`, `(` or quotes. So
+`session.ts`, `src/entities/oauth/` and `.github/workflows/**` are citations, while
+`ecr ci`, `label:<agent>`, `knex.raw()`, `critical` and a bare `.ts` are prose. Fenced
+code blocks are skipped whole: they are examples, not claims about the tree.
+
+**Shape plus the filesystem** (`pathishCandidates`), for the citations shape cannot
+settle. A reviewer of this feature named the case: a Terraform prompt citing
+`eas-build-worker/terraform`, `general-central/{module,production}` and `finops`, with
+"this is very likely going to drift" [observed] — not one of those has an extension, and
+`anthropic/claude-opus-5` is shaped identically while naming no file. Syntax cannot tell
+them apart, so an extensionless token counts as a citation exactly when it *names
+something real*: probed against the scope's own subtree first, then the repo root (a
+scoped prompt citing `alerts/` means its own tree even when the root has one too), brace
+lists cut back to their fixed prefix. A token carrying `*` resolves as a glob instead,
+scope-rebased when that is what matches, so the suggested `glob:` ref itself resolves.
+Model ids resolve to nothing and stay prose.
+
+The consequence is deliberate: an extensionless path that had already drifted before
+adoption is invisible (nothing distinguishes it from prose), while every one that is true
+today gets pinned and will be caught the moment it moves. This mechanism prevents future
+drift; it does not retroactively find old drift.
+
+The escape hatch is explicit and per-token: `@ref-ignore knex.raw()` in a comment.
+Anything the heuristic misclassifies is one short line away from silence, which is why
+the rule can afford to be strict rather than advisory.
+
+**Invariant:** the check never rewrites a prompt. It reports; a human decides whether the
+ref or the prompt was wrong. A stale citation often means the *guidance* is stale, not
+just the path.
+
+## Structural Refs Need No Annotation
+
+Some refs the config already declares, so they are checked without annotation:
+`enforceAgents` ids must exist as `agents/<id>.md` in the ROOT setup (that is where the
+loader resolves them, see [LLP 0006][routing]), every scope's `config` must point at a
+real `.expo-code-review/` directory inside the repo, and every scope glob must match at
+least one file — a scope whose paths match nothing ships prompts that review nothing.
+
+## What Gets Scanned
+
+Setup dirs are found by walking the tree, not by reading `routing.jsonc`: a scope dir the
+manifest forgot still ships prompts, and its stale refs are exactly what this exists to
+surface — the same reason `ecr verify-config` sweeps on disk instead of trusting the
+manifest ([LLP 0007][verify]). Inside a setup dir the scan covers prompts and configs
+(`.md`, `.json`, `.jsonc`, `.txt`) and skips dot entries, so `.runs/` artifacts are never
+scanned. Dot directories elsewhere are skipped too, which keeps `.claude/worktrees/`
+checkouts of the same repo from being swept as if they were scopes.
+
+## Run Points: Command and Review
+
+`ecr ref-check` exits 1 on any problem: that is the gate, for CI or a pre-commit hook.
+
+The review path also runs it, and never fails a PR's checks with it — that invariant
+holds ([LLP 0002][pipeline]). Instead the review *advises*: broken refs in the setup
+become a note the reviewer comment carries, and `citedPathsTouchedBy` adds the drift
+signal a static check cannot give — "this PR changes code your reviewer prompts cite, so
+the guidance may need updating" — even when the ref still resolves. In CI the config
+comes from the trusted base ref while refs resolve against the PR head tree, so a PR that
+moves cited code is reported against the config that will actually review it.
+
+## Two Checkers, One Grammar
+
+The engine repo now has two ref checkers, and they scan overlapping files: `./ref-check`
+(the LLP corpus validator, which walks the whole tree) and `ecr ref-check` (setup dirs
+only). Running both surfaced two genuine conflicts, where one checker failed an
+annotation the other accepted [observed]:
+
+- `glob:` targets were unknown to `./ref-check`, which read them as a literal path and
+  reported "path not found".
+- Documenting the syntax broke both: a usage line containing the comment form with a
+  `<target>` placeholder was collected as a real ref, and so were the README's fenced
+  examples — the docs that teach refs were the first thing the checkers rejected.
+
+All of it is fixed in the grammar rather than per-checker: `glob:` is understood by both,
+a target starting with `<` or a backtick is a documentation placeholder, and an annotation
+inside a fenced code block is an example that neither checker resolves.
+
+Ownership stays split by target kind, not by file: an `LLP NNNN` target belongs to the
+design corpus and its own checker, so `ecr ref-check` neither resolves nor counts one —
+it owns exactly the refs that cite the reviewed repo's code. That split is why the
+templates can keep their engine annotations and still scaffold a repo that passes
+`ecr ref-check` on day one (asserted in `init-scaffold.test.ts`). An earlier attempt had
+`ecr init` strip those annotations while scaffolding; it mixed the two mechanisms and
+broke the "workflow templates land byte-identical" invariant [observed]. Parsing is what
+must be right: `LLP 0009#anchor` is one target containing a space, and taking the first
+whitespace-separated token left a bare `LLP` that read as a broken path.
+
+**Invariant:** the grammar is shared. A change to target kinds, the placeholder rule, or
+the glob dialect must land in `./ref-check` and `src/core/config-refs.ts` together, or the
+same annotation will pass one checker and fail the other.

+# LLP 0013: Built-in Platform Research
+
+**Type:** Explainer
+**Status:** Active
+**Systems:** Research, Security, Runtime, Config, Packaging
+**Author:** Expo
+**Date:** 2026-08-06
+**Related:** [LLP 0001](0001-trust-model.principles.md), [LLP 0002](0002-review-engine-pipeline.explainer.md), [LLP 0003](0003-model-runtimes-and-credentials.explainer.md), [LLP 0006](0006-config-schema-loading-routing.explainer.md), [LLP 0009](0009-adoption-templates-and-ci-workflows.guide.md)
+
+`@expo/code-review-cli` ships a documentation-search MCP as a second binary in
+the same npm package. ECR invokes it before model startup and passes the resulting
+passages to reviewer prompts as bounded, explicitly untrusted evidence. The model
+never receives the MCP as an agent tool.
+
+## One Package, Two Binaries
+
+The package exposes `ecr` and `review-research-mcp`. Keeping both in one package
+makes the query router, MCP protocol, source adapters, tests, and review integration
+one versioned unit. ECR does not resolve the MCP through `PATH`: it starts the
+package-relative entry point with the current absolute Node executable. Root config
+supplies only enablement, bounds, and an optional absolute fallback index path—not an
+arbitrary command, endpoint, host, or argument vector.
+
+The MCP remains a process boundary rather than an in-process import. Its stdout is
+the only result channel, its environment is an allowlist, it runs from the OS temp
+directory, and ECR caps its runtime and output. A failure is logged and review
+continues without research; it never skips or weakens an ordinary review pass.
+
+## Search, Fetch, and Optional Index Boundary
+
+`review-research-mcp serve` uses Brave Web Search as discovery for non-Expo
+providers. Each request combines the already-sanitized API/concept query with a fixed
+provider-owned `site:` scope. The endpoint is fixed, redirects are rejected, response
+size/time/hit count are capped, and only the fixed `BRAVE_SEARCH_API_KEY` credential
+is forwarded into the MCP child. Search titles, snippets, and ranking are untrusted
+discovery hints, never evidence.
+
+Every discovered URL must independently pass the provider's exact HTTPS host/path
+allowlist before a fetch begins. Redirects are handled manually and must remain on
+the provider's request allowlist; content type, body size, redirect count, timeout,
+and fetched-page count are bounded. The fetched official body—not the search
+snippet—is parsed, locally ranked, truncated, and returned as evidence. Apple
+documentation uses its structured DocC JSON, including symbol and availability
+metadata. Search-engine sparsity produces an empty result and never broadens the
+trust boundary.
+
+## Direct URL Fetch Boundary
+
+The MCP also exposes `fetch_platform_doc` for a caller that already has an exact
+documentation link. It infers the narrowest matching provider from a fixed ordering,
+or accepts a fixed provider id as a hint when corpora overlap. The supplied URL must
+pass that provider's canonical HTTPS host/path allowlist before network access. The
+request adapter, every redirect, content type, timeout, and response size then pass
+the same checks as a search-discovered document. The tool fetches one page only and
+returns at most five bounded extracted passages. An optional query ranks passages
+within the fetched page; it cannot turn the operation into discovery.
+
+This path is useful for documentation links already present in review context. For
+Apple symbol links it converts the canonical `/documentation/...` URL into Apple's
+allowlisted DocC JSON request URL, preserving the human-facing canonical URL in the
+result. A URL that matches no provider is rejected before `fetch`; a redirect outside
+the selected provider's separate request allowlist is rejected before following it.
+
+Expo-routed queries use the fixed public Expo Algolia endpoint. Its browser-visible
+key is search-only; redirects are rejected, response size/time/hit count are capped,
+records are schema-validated, and canonical result URLs must remain on
+`docs.expo.dev`.
+
+OkHttp uses the fixed official `lysine.dev` static search index because the newly
+migrated feature pages are not yet comprehensively represented in Brave. The index
+has the same response-size/schema/URL constraints, is cached only within the MCP
+process, and can never admit a URL outside the OkHttp provider allowlist. Brave is a
+fallback when that first-party index is unavailable.
+
+`review-research-mcp update` is a separate, operator-invoked command for trusted
+scheduled jobs. The updater uses exact HTTPS host/path allowlists, manually
+revalidates redirects, checks response content types, and bounds response size,
+crawl depth, page count, timeout, and delay. The Expo crawl supplies a local fallback;
+precise Expo search uses the live query rather than pretending an empty-query result
+page is a complete Algolia index.
+
+The crawler is not part of the ordinary review workflow. An adopter requiring an
+offline fallback may run `update` in a separate scheduled secretless job from a
+pinned package and trusted checkout. That job must execute no PR code, receive no
+model credential, and publish a verified read-only index artifact.
+
+The generated index is deliberately not published in the npm package. Documentation
+changes independently of ECR, and coupling a snapshot to every CLI install would make
+releases and invalidation expensive. If supplied, an absolute trusted-base
+`research.indexPath` is fallback evidence when remote discovery fails or misses.
+Research-enabled reviews bypass result-cache reuse because remote search,
+documentation, and optional index content can change without a config change.
+
+## Query and Prompt Boundary
+
+ECR derives queries only from added native-code identifiers. It removes comments,
+string literals, deleted lines, file paths, and raw snippets; caps identifiers and
+query count; and selects named providers from known code signals. The MCP tool
+metadata tells direct clients to use exact symbols plus one member, behavior, or
+constraint term, and to retry broad results with a narrower symbol. It explicitly
+rejects prose, code, package/import names, paths, secrets, and sensitive context as
+query material. MCP output is
+schema-validated, limited to HTTPS URLs from the requested provider, truncated,
+sanitized, and wrapped in an untrusted platform-research fence. The Brave credential
+is never written to MCP output, prompts, logs, or run artifacts. Issue tracker text
+keeps distinct provenance and is never presented as an API contract.
+
+## Research Provenance and Citations
+
+Research is observable without exposing the Brave key or full responses. Each review
+prints the exact bounded queries and every accepted result's title, provider,
+provenance class, and canonical URL. GitHub Actions receives that same data in its
+step summary. The JSONL run log additionally stores at most the already-bounded
+passage returned to the reviewer so operators can determine whether research was
+useful after the fact; it still excludes PR title/body and model transcripts.
+
+The prompt may select a source for a finding only by copying its exact title and URL
+from injected research evidence. Model output crosses an engine-side grounding seam:
+URLs absent from the trusted prepass are removed and accepted titles are restored
+from the canonical evidence. Grounded sources are unioned across duplicate reviewer
+findings, preserved through coordinator rewrites by the finding fingerprint, stored
+in hidden comment state, and rendered as visible links. Sources do not participate
+in fingerprints or severity/decision logic, and findings that did not materially use

+## Installation-Specific Research Is Deferred
+
+The built-in source catalog covers Apple, Android, platform releases, Swift
+Evolution, Media3, Glide, OkHttp, Kotlin coroutines, Gradle/AGP, selected JetBrains
+issues, Expo, React Native, Reanimated, Gesture Handler, Screens, and Worklets.
+The canonical OkHttp host is backed by both the
+[maintainer's transfer announcement](https://jakewharton.com/the-lysine-contingency/)
+and [Commonhaus's project-transfer record](https://www.commonhaus.org/activity/315.html).
+A later design may let adopters select or add research capabilities through trusted
+root configuration, similar to agent files. That extension must not turn arbitrary
+PR-controlled URLs, commands, parsers, or executable plugins into review inputs. New
+remote sources still need an operator-controlled host/path allowlist and provenance
+class; scope configs remain unable to alter the research runtime or index.
+
+Expo skills solve a different problem: pinned procedural guidance for how a reviewer
+should reason or act. They may later be supplied as versioned, separately labeled
+trusted context selected from root configuration. Documentation results remain
+untrusted evidence with canonical sources. A crawler result must never install,
+activate, or rewrite a reviewer skill.
