feat: post inline PR comments for in-diff findings

Findings anchored to a line in the PR diff are posted as inline review
comments on that line (full rationale/sources/suggestion there); the main
comment renders them short — title, links, one-line rationale — with a link
to the thread. The main comment stays the single durable state store.

- Root-only config: inline { enabled: false, maxComments: 20 }
- Per-finding byte-0 marker + author = thread identity; threads patch in
  place, sticky cap never evicts a live thread, retired threads with human
  replies are stubbed (neutral text), bare ones deleted
- Teardown only when the target set is provably complete: failure reviews
  now set couldNotComplete, --scopes partial runs and /dismiss re-renders
  are additive-only (truncated aggregate state cannot prove a finding gone)
- Inline replies feed author feedback via threadFp (matches in every match
  mode; clearing still requires the unquoted id: token); review-comment ids
  are stored negated to stay collision-free vs issue-comment ids, with
  magnitude-within-stream recency and a cross-stream pin-lift refusal
- hasUnquotedInlineMarker backstop keeps our own inline bodies (which carry
  an unquoted id: token) from ever matching as replies; quoted copies still
  count as genuine quote-replies
- Creates verify the live PR head, mutations run sequentially, 403/429
  aborts the sync, every sync writes a step-summary audit line

+# Plan: inline PR comments for in-diff findings (rev 2, post adversarial review)
+
+## Goal
+
+Findings anchored to a line in the PR diff land as inline review comments on
+that line. The main issue comment keeps every finding but renders an inlined
+one SHORT: title + one-line rationale + link to the inline thread. The main
+comment stays the single durable state store (embedded state, dismissals,
+feedback records, pins, `/dismiss` target). Inline comments are a derived
+presentation layer, converged on every run.
+
+## Non-goals (v1)
+
+- No formal `POST /pulls/{n}/reviews` review event: a batched review is atomic
+  (one bad anchor 422s the whole post) and cannot be upserted across runs.
+  Individual review comments isolate failures and PATCH in place.
+- No multi-line comments; single `line` + `side: "RIGHT"` only.
+- No GraphQL thread resolution, and no detection of author-resolved/outdated
+  threads. Accepted risk: the PR author can collapse inline threads; the main
+  comment therefore keeps a one-line rationale per finding (see Short form).
+- `ecr feedback` retroactive crawl keeps reading issue comments only. The
+  review-comments fetch in `replyComments` is gated on the reporter having an
+  ENABLED `inline` option, so the crawl (which passes none) gains no fetches.
+- Scopes removed from the routing manifest strand their comments — same
+  pre-existing behavior as their main comments.
+- Break-glass (`postSkipNote`) leaves inline threads untouched even though it
+  overwrites the embedded state. Accepted, documented.
+
+## Config
+
+Root-only key in `ReviewConfigSchema`, locked out of scope configs with
+`z.never` like `feedback`:
+
+```jsonc
+inline: {
+  enabled: false,        // ship dark
+  maxComments: 20        // cap per posted comment's reporter (per PR in single/
+                         // legacy mode; per scope in per-scope mode — documented)
+}
+```
+
+Wired into `LoadedConfig`, `load.ts` defaults, all five reporter construction
+sites, and `reviewPostingConfigFingerprint` (posting behavior changes with it,
+so a saved deferred review must not post under a different inline policy).
+Turning it OFF later leaves existing threads up (documented; `clear()` still
+sweeps them on mode switches, and a manual cleanup is possible).
+
+## Inline comment identity
+
+Marker, at byte 0 of the body, parsed with an ANCHORED regex and a hex-only
+charset:
+
+```
+<!-- <tag>:inline:fp=<[a-f0-9]{6,64}> -->
+```
+
+- Identity = author (`user.login === ownLogin`) + anchored marker; marker alone
+  is never identity (selectOwnComments model). ownLogin unresolvable ⇒ nothing
+  is ours AND no creates either (fail closed, no duplicate storms).
+- Byte-0 anchoring also narrows the shared `github-actions[bot]` confused-deputy
+  risk: an echo-bot that prefixes any content fails the anchor.
+- fp is the id the owning main comment renders (plain, or scope-namespaced for
+  the aggregate). Substring safety vs `<!-- tag -->` / `<!-- tag:scope -->`
+  holds in both directions (closing ` -->` differs), incl. a scope named
+  `inline`.
+
+## Inline comment body
+
+Marker line, then the finding rendered in full (severity, title, category,
+`id:<fp>` token, rationale, sources, suggestion — every model-written field
+through `stripStateMarkers`), then a footer: "Reply here to respond; write
+`id:<fp>` in your reply (unquoted) to formally answer it."
+
+**Self-reply backstop (was blocker):** the body carries an unquoted `id:` token,
+and today's `OWN_COMMENT_RE` (`:state=|:fingerprints=`) would NOT exclude it if
+identity/tag filters ever miss (bot-login fallback, commentTag rename, second
+posting identity). Fixes, all three:
+- `responses.ts` gains a tag-independent backstop: a body whose UNQUOTED lines
+  contain `:inline:fp=` is never treated as a reply (quoted lines excluded so a
+  GitHub "Quote reply" of our inline comment — which copies the marker behind
+  `> ` — still counts as a genuine reply).
+- `replyComments` applies the same unquoted-line rule for the tag-specific
+  marker.
+- Test: an inline body is never matched as a reply even with `ownLogin: null`
+  and a foreign tag; a quote-reply containing the quoted marker IS matched.
+
+## Reporter mechanics
+
+New option `inline?: LoadedConfig["inline"]`.
+
+### Fetch layer
+
+`fetchAllReviewComments()`: paginated GET `repos/{repo}/pulls/{n}/comments`
+(fields: id, body, path, line, user.login, html_url, in_reply_to_id,
+author_association). Cached in a MODULE-LEVEL map keyed
+`prNumber\nrepo\ncwd` (the prAuthorByPr pattern) with the same 30s TTL and
+invalidate-on-mutation — routed single-mode runs call `clear()` on a fresh
+reporter per scope, and per-instance caching would multiply listings. Note:
+this endpoint DOES honor sort/direction (unlike issue comments) — do not copy
+that rationale comment; a full scan is still needed.
+
+### Sync
+
+`syncInline(targets, link, opts: { teardown: boolean })` runs inside
+`report()` / `reportAggregate()` before rendering; returns `Map<fp, url>`.
+
+Targets = ACTIVE findings only (not dismissed, not reply-cleared, not
+requalified) with `line != null` and `diffLines.get(file).has(line)`.
+
+**Cap (sticky, was churn bug):** order candidates by severity rank then fp
+(deterministic); fill slots preferring fps that ALREADY have a live inline
+comment, then admit new ones. A live thread is never evicted to create a new
+one.
+
+**Teardown gating (was blocker):** stubs/deletes run ONLY when
+`opts.teardown` is true, which callers set as:
+- `report()`: `!review.couldNotComplete`.
+- `reportAggregate()`: caller-passed flag — ci.ts passes
+  `!scopesFilter && results.every(r => !r.review.couldNotComplete)`. A partial
+  `--scopes` run or any failed scope makes the run additive-only (creates +
+  patches, no stubs/deletes), because carried/truncated/failed state cannot
+  prove a finding is gone. (`scopedFingerprint` is opaque hex — a per-scope
+  stale set cannot be derived from fps, so the gate is all-or-nothing.)
+- `applyDismissal`: never computes a stale set. Additive-only: stub threads of
+  the explicitly dismissed fps; on `/undismiss`, re-patch the full body if the
+  finding is present in state (skip if truncated away).
+- Prereq fix: both failure literals (`ci.ts` legacy catch and
+  `failureReview()`) gain `couldNotComplete: true` — today they post
+  empty-findings reviews WITHOUT the flag and would tear everything down. Side
+  effects checked: the decision label becomes the accurate "No review — every
+  pass failed", and caching is unaffected (failures already never carry
+  inputHash).
+
+**Stub text (was blocker):** neutral — "This finding is no longer tracked
+inline — see the main review comment for current status." Never
+"resolved/dismissed": a capped-out or drifted finding is still active.
+
+**Mutations** (sequential, never parallel):
+- create: POST with body/commit_id=headSha/path/line/side. Creates require
+  headSha AND a live-head check: one `gh pr view --json headRefOid` per sync
+  (only when creates exist); mismatch ⇒ skip creates, log (a mid-review push
+  means our diff no longer matches the head; a stale commit_id can silently
+  anchor to wrong code, and a force-push 422s every create).
+- patch: only when the normalized body differs (`\r\n` → `\n`) — no PATCH-per-
+  finding-per-run forever.
+- stale (teardown only): thread has replies ⇒ PATCH to the neutral stub
+  (marker kept, so a returning finding revives the thread); no replies ⇒
+  DELETE. Reply detection: any listed comment with `in_reply_to_id` == our id
+  (same snapshot; the reply-between-list-and-delete race is accepted, noted in
+  tests).
+- duplicates (crash window): keep newest per fp, older are stale.
+- 422 on create ⇒ log once + skip that finding (renders full-form). 403/429
+  (secondary rate limit) ⇒ log + abort ALL remaining mutations this run.
+- Audit (was silent): stderr one-liner + step-summary line:
+  `inline sync: N created, N patched, N stubbed, N deleted, N failed`.
+
+Every mutation individually try/caught; the inline layer never blocks the main
+comment. Listing failure ⇒ empty map, no mutations.
+
+### clear()
+
+Extends to inline comments under this reporter's tag, gated on marker+author
+only (NOT on `enabled`, so mode switches clean up after a disable): replied
+threads are STUBBED, bare ones deleted — never delete a thread humans wrote in
+(ci.ts calls clear() on mode switches and scope reconciliation). This also
+covers the fp-namespace flip on per-scope↔single switches, symmetric with how
+main comments are cleared today.
+
+### Main-comment short form
+
+- `LinkContext.inlineUrls?: Map<string, string>`. NEVER mutate the shared
+  routed-flow `link` object — render with a copy `{ ...link, inlineUrls }`.
+- `renderFindingLines` with an inline URL: `- **title** —
+  [file:line](thread-url) _(category)_ · id:… · 💬 [inline](url)` + reply
+  annotation + ONE-LINE truncated rationale (~160 chars, word boundary) — the
+  audit trail survives the author collapsing/resolving inline threads.
+  Sources/suggestion/full rationale live inline only. Missing URL ⇒ full form
+  (tested).
+- Embedded state unchanged.
+
+### Inline replies → feedback
+
+- `replyComments()` maps review comments too — ONLY when
+  `options.inline?.enabled` (keeps `ecr feedback` crawl and non-inline repos at
+  zero extra fetches). Excludes own login; excludes bodies whose unquoted lines
+  carry our markers.
+- **Id namespace (was collision risk):** review-comment-sourced ReplyComments
+  get `id = -reviewCommentId`. Negative ids flow into FeedbackRecord.commentId
+  (schema unchanged — number stays a number) and are consistent across runs, so
+  mergeFeedback's `commentId` equality and buildAdjudicationItems' body lookup
+  stay collision-free vs the positive issue-comment space.
+- `applyPins` gains a cross-stream guard: a pin is lifted only by a maintainer
+  record whose commentId is newer AND in the SAME stream (same sign). A
+  different-stream comparison is undecidable ordering ⇒ keep the pin (fail
+  closed).
+- `ReplyComment.threadFp?: string`: set when the reply's `in_reply_to_id`
+  resolves to OUR (author+anchored-marker) top-level inline comment's fp.
+  `matchReplies` treats a known threadFp as a match in EVERY `match` mode
+  (structural signal, not text matching; documented + tested). `citedId` is
+  unchanged: clearing still requires the replier's own unquoted `id:` token.
+- Newest-wins across streams: negative ids lose to positive ones by raw
+  comparison; acceptable because only the newest record per fp matters and a
+  same-fp cross-stream tie is rare; the applyPins guard removes the dangerous
+  consequence.
+
+## Files touched

+- `src/core/deferred-review.ts` — fingerprint includes `inline`.
+- `src/reporters/github.ts` — review-comments fetch (shared cache), syncInline

+## Why not just `claude -p "review this diff"`?
+
+A one-shot prompt in a workflow works — until the failure modes show up. The
+engine exists for those:
+
+- **Everything the reviewer reads is attacker-controlled.** The diff, the PR
+  description, and the repo files are all input an outside contributor wrote —
+  and a bare CLI run obeys instruction files from that same checkout
+  (`CLAUDE.md`, `.mcp.json`, plugins) while holding the model credential and
+  comment token. Here, configuration comes only from the trusted base commit,
+  those files are scrubbed before the engine starts, and every pass is read-only
+  ([details below](#the-security-gap-specifically)).
+- **Confident-but-wrong findings post as-is.** Raw model output is the review.
+  Here, every finding is quote-grounded against the real file and criticals are
+  adversarially verified before anything is posted.
+- **Failures read as silence or approval.** A one-shot call that stalls, gets
+  rate-limited, or returns garbage either fails the job or posts nothing. Here,
+  each failure class has its own bounded retry, a failed run never renders as a
+  clean result, and CI always posts a terminal comment.
+- **Big diffs blow the context window.** Large PRs are chunked with a separate
+  cross-cutting pass for multi-file issues; specialist agents run in parallel; the
+  prompt layout is cache-stable, and every run reports tokens, cost, and cache
+  hit rate.
+- **Noise wastes the model's attention.** Lockfiles, generated bundles, and
+  binaries are filtered before the model sees them — recorded, never silently
+  dropped.
+- **Comment spam.** One fingerprinted comment updated in place, with `/dismiss`,
+  severity floors, inline ignores, and author-reply tracking — not a new wall of
+  text per push.
+- **Review prompts rot.** `ecr ref-check` fails when a prompt cites code that
+  moved or vanished, and every run warns loudly if a provider substituted a
+  different model than configured.
+
+### The security gap, specifically
+
+A review bot is a process holding a model credential and a GitHub write token
+that reads attacker-controlled input for a living. A bare `claude -p` workflow
+typically checks out the PR head and hands the model broad tools — so a PR that
+says the right words can run code, read secrets, or post as you. The trust model
+here ([LLP 0001](./llp/0001-trust-model.principles.md)) is built around that:
+
+- **No PR-controlled code is ever built or executed.** The engine runs as the
+  published npm package via `npx`; the scaffolded workflows check out only the
+  base commit, with `persist-credentials: false`.
+- **The model has no write tools and no ambient web.** `Read`/`Grep`/`Glob` only
+  — never `Bash`, `Edit`, or `WebFetch`. An injected instruction has nothing to
+  act with; the worst it can do is produce a wrong finding, which then has to
+  survive verification.
+- **Review policy is not PR-editable.** Config, prompts, rosters, and the auth
+  mapping load from the PR's immutable base commit; `tokenEnv` is honored in
+  exactly one root-owned place, enforced at the schema level and again by an
+  independent CI guard step.
+- **Credentials are compartmentalized.** Child environments are allowlists that
+  omit ambient keys; the research MCP never sees a model credential, the model
+  process never sees the search key, and outbound research queries fail closed
+  on credential-shaped input.
+- **Untrusted text can't impersonate the reviewer.** PR prose travels inside
+  sanitized boundary markers, and every `<!--` in it is escaped so a forged
+  state marker can't hijack the dismissal list. `critical`/`secrets` findings
+  can't be dismissed or cleared by replies — enforced in code, not the prompt.
+- **The blast radius is capped by design.** The review is advisory and
+  comment-only: even a fully fooled model can't approve, merge, or block
+  anything.

+The boundary, in brief:
 
-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

-settings and slash commands disabled; OpenCode receives the same fixed local command.

+- **Bounded egress, not a confidentiality boundary.** Queries are normalized and
+  sanitized (credential-shaped or secret-labeled input fails closed); direct URLs
+  must be plain HTTPS on a fixed provider host/path allowlist; redirects, response
+  sizes, content types, and per-call deadlines are enforced server-side. The model
+  still chooses the query terms, so enable research only where repository-derived
+  terms may be shared with Brave and the documentation providers.
+- **The server never sees a model credential.** ECR starts the MCP from its own
+  installed package through a wrapper that rebuilds the child environment from an
+  explicit allowlist; the Brave key never enters the model process either.
+- **Audited and citable.** Every outbound query and returned result is audited (job
+  log, Actions step summary, `.runs/reviews.jsonl`). A finding can cite only URLs
+  actually retrieved during that review, and the verifier strips citations whose
+  passage does not support the claim.
+- **`maxQueries` bounds MCP calls, not HTTP requests** — one search can fan out to
+  many discovery and page fetches, so each call reports its own request ledger and
+  the run reports totals.

-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 SDWebImage, 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.
-The tool metadata also includes an explicit provider map, so the reviewing model can
-distinguish core platform APIs from release notes, dependency-owned documentation,
-build-tool references, and issue-tracker context before choosing a corpus.
-Reviewer instructions require grounding whenever a judgment depends on an externally
-owned API contract, whether the evidence confirms a finding or dismisses a candidate
-as safe; model memory alone is not treated as sufficient for those decisions.
-Native source keeps its platform context: Apple or Android documents the OS contract,
-while an explicit dependency provider documents library-owned behavior. Providers are
-additive when both contracts matter. A path under `packages/expo-*` does not by itself
-route Swift or Kotlin code to Expo's JavaScript documentation.
-
-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. It returns normalized extracted text, never
-raw HTML or DocC JSON. An optional `query` selects context only within that one page;
-it never broadens discovery. Context expands progressively:
-
-- `focused` returns the best passage plus adjacent passages.
-- `section` (the default) returns a contiguous window of at most 12,000 characters
-  around the best passage.
-- `document` returns at most 20,000 characters of extracted page text and should be
-  used only when the contract is spread across the page.
-
-The response reports returned and original character counts, whether it was truncated,
-the anchor passage id, and bounded available passage ids. Search results also carry
-neighboring passage ids so an agent can recognize when more local context exists. 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.
-
-Reviewers also emit a bounded `researchDecisions` record only when documentation
-materially confirms a finding candidate or proves one safe. ECR grounds those records
-against the exact MCP audit and discards ungrounded claims. After verification and
-suppression, the log and Actions summary report final findings with citations,
-supported and dismissed candidates, and unique audited results materially used versus
-unused. Counts use canonical URLs rather than passage count, so repeated hits do not
-inflate usefulness.
-
-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
-allowlist. Brave remains a fallback if that official index is unavailable.
-
-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
-`review-research-mcp update`. This is operator/scheduled offline tooling, not a
-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
-documentation search continues to return citable API evidence. Dynamic skills or
-instructions retrieved from documentation must never become executable reviewer
-instructions.

 ## Monorepos (routing manifest)
 
 A monorepo can route different subtrees to different reviewer rosters from a single
 infra-owned manifest. There is still **one workflow, one `ecr ci` process** per PR:
-it reads the changed files once, assigns each to exactly one scope, reviews each
-active scope over only its files, and renders one comment. Because it is a single
-writer in a single process there is no comment/check race and no locking.
+it reads the changed files once, assigns each to exactly one scope (scopes are
+ordered, the **last** match wins — CODEOWNERS discipline), reviews each active scope
+over only its files, and renders one comment — a single writer, so no comment race
+and no locking.

 ### Security
 
-- **auth and research are locked to the root.** `tokenEnv` (which env var becomes the model
-  credential) is honored in exactly one place: the root `config.jsonc` or
-  `routing.jsonc` `defaults.auth`. A scope config declaring `auth`/`breakGlass`/`research`
-  **fails to parse** (Zod-level rejection). A scope declaring `research` also fails,
-  so PR-controlled routing cannot select a different host index. The CI guard step independently
-  sweeps every `.expo-code-review/config.jsonc`/`routing.jsonc` repo-wide and refuses
-  to run unless `tokenEnv` appears exactly once, in a root-owned file, equal to
-  `ECR_EXPECTED_TOKEN_ENV`. A routing manifest can never widen exposure — globs only
-  choose *which roster* reviews a file, never *which secret* is sent.
-- **enforceAgents can't be weakened.** Agents listed in `defaults.enforceAgents`
-  (e.g. `security`) are injected into every scope with `alwaysRun`, taken from the
-  root roster — a scope defining a same-id agent gets the root one, so a team can't
-  shadow the enforced reviewer with a weaker version on its own subtree.
-- **Configuration comes from the PR's trusted base commit.** In `ecr ci`, review
-  policy and reviewer configuration — `config.jsonc`, `routing.jsonc`, prompts,
-  models, and the auth mapping — load from the PR's immutable **base** commit,
-  materialized via the GitHub API. The PR head is untrusted data: it is
-  materialized separately (pinned to its immutable OID) purely as source content
-  to read and verify against. A PR editing rosters, prompts, or routing is
-  reviewed under the **previous** config; its changes activate after merge. If
-  the base commit can't be materialized, the run fails closed (one terminal
-  comment) — it never falls back to the checkout. A scope config that is new in
-  a PR is reviewed with the root config until it merges.
-- **The model runtime never sees PR-owned ambient config.** The head worktree the
-  agents read from is scrubbed of runtime configuration before the OpenCode
-  server starts: `opencode.json{,c}`, `.opencode/` (plugins), `AGENTS.md`,
-  `CLAUDE.md`, `.claude/`, `.mcp.json`, `.cursor*`, and `.env*` at every depth.
-  A PR can't install a plugin, MCP server, instruction file, or `.env` into the
-  process that holds the model credential and the comment token. (Changes to
-  those files are still reviewed — their diffs are inlined in the prompt — but a
-  finding citing one can't be re-read during verification; that's the tradeoff.)
-- **The scaffolded workflows check out only the base commit** with
-  `persist-credentials: false`; the CLI's own git fetches authenticate through
-  `gh` from `GH_TOKEN`, so the token never lands in `.git/config` or argv. The
-  CLI enforces the trust model itself, so a custom workflow that checks out the
-  PR head still gets base-commit configuration. The temporary escape hatch
-  `ecr ci --unsafe-config-from-head` restores the old behavior with a loud
-  security warning and will be removed on a minor boundary.
+Enforced in code and by an independent CI guard step, not by convention:
 
-Ownership is enforced with CODEOWNERS: `/.expo-code-review/routing.jsonc @your-infra`
-(the single authoritative router) and `/apps/api/.expo-code-review/ @your-api-team`
-(each team owns only its own scope dir). Rerouting globs is gated behind infra review.

-- Very short prompts may show `cache read 0`: prompts below the model's minimum
-  cacheable size (~1–4K tokens depending on the model) are silently not cached.

-- **Stall detection** — a pass whose reply stops changing entirely (no new tool call,

-  *with* recent 429 evidence is throttling, not a wedge — the pass waits in 90s
-  beats (without consuming its one retry) instead of re-sending its whole context
-  into a limited account; explicit 429 errors retry on a slow 15s/45s/90s schedule.
-  Subscription (oauth) runs also default to `concurrency` 3 instead of 6, since one
-  account may be serving several PRs' reviews at once. Rate-limit events are
-  reported in the job log and the run log (`rateLimitEvents`), so throttling is a
-  visible fact about a run, never a mystery slowdown.
-- **Soft landing on timeout** — at either cap, the run is interrupted and the agent
-  is asked to return the findings it already has, rather than discarding its work.
-  Tools are disabled for that request, so the salvage step can't resume investigating
-  instead of answering.
-- **Subdivide-on-timeout** — a reviewer pass that times out with nothing to show has
-  its chunk split in half and the halves re-reviewed (recursively, down to a single
-  file), then a fast **no-tools fallback** over the inlined diff (the cross-file pass
-  skips straight to the fallback, which still sees the whole diff). Only a genuinely
-  un-reducible pass reports a coverage gap — and it is always reported, never silent.
-- **Parse failures are retried** (same session, then once in a bounded fresh
-  session) — separate from the timeout path.
-- **Transient API errors are retried** (bounded backoff on 429/5xx/network) —
-  distinct from both the timeout path (abandon) and the parse path; a one-off blip
-  no longer drops an entire pass.
-- **Auth failures surface once, and fail fast** — `ecr` checks the configured
-  provider's credential at startup and stops with one clear message if it's missing
-  (rather than failing every pass); a credential rejected mid-run (401/403)
-  collapses into a single actionable coverage note pointing at
-  `auth.tokenEnv`/`REVIEWER_MODEL`.
-- **A failed run never reads as "Approve"** — all passes fail → "could not
-  complete"; some fail → never a clean approve, and coverage-reduced.

-  merged deterministically and still posted.
-- **Coverage notes** — passes that timed out/failed are listed (routine noise
-  filtering is *not* flagged — it's expected and stays in the run log).
-- **CI always gets a terminal state** — on any failure the PR gets a "didn't run"
-  comment, not a stuck reaction and silence.

+A pin outranks both, because `/undismiss` is the human's last word that a finding
+still stands [observed] (`src/core/prior-review.ts:statusOf`).
+
+`answered` means the reply actually **cleared** the finding, not that someone
+replied — and the test is `feedbackApplied`, the same predicate the reporter uses,
+injected rather than imported so the two cannot drift [observed]
+(`src/core/prior-review.ts` `replyCleared` parameter; `src/commands/ci.ts` binds it
+to the run's feedback config). This is load-bearing, not tidiness: LLP 0011 floors
+`critical`/`secrets`/`security` in code so no reply can clear them, and a block
+that labelled such a finding "a human replied to this" would hand the reviewer a
+reason to drop it — reinstating, through the prompt, exactly the suppression the
+floors refuse. A quote without the `id:` token, a third-party commenter, and a
+finding a maintainer pinned back all stay `open` for the same reason. Each record
+also goes through `dropStaleVerdict` against the reviewed head first, the same
+rule both merge paths apply [observed] (`src/commands/ci.ts`, `mergeFeedback` in
+`src/reporters/github.ts:178`): a verdict is a claim about SOURCE and
+`fingerprintFinding` excludes the line number, so without it an accepted rebuttal
+from an earlier revision would keep marking a finding answered after the code it
+judged was edited away.
+
+It is untrusted, and treated so. The titles and paths are model output produced
+by reading an untrusted pull request — `stripStateMarkers` exists precisely
+because a forged marker can arrive inside a model-written rationale (see [LLP
+0011](0011-author-feedback.explainer.md)). Each entry is therefore flattened
+through `flattenUntrusted` onto a single line and the assembled block is swept
+for a forged `----- BEGIN/END PREVIOUS REVIEW -----` fence, the same defense the
+context file gets [observed] (`src/core/prompts.ts` `PRIOR_REVIEW_BOUNDARY`).
+
+Two boundaries are deliberate. The **coordinator never receives it**: it merges
+and decides, and handing it the previous decision is how a decision drifts by
+inheritance rather than by evidence. And the wording frames prior findings as
+claims to re-check, never as conclusions to carry forward — a reviewer that
+restates last run's list without re-deriving it has stopped reviewing, and recall
+is the product. The block says so explicitly, including that absence from the
+list means nothing.
+
+It is **not** part of the review-cache key, which is a deliberate exception to
+"every input joins the hash" [observed] (`src/core/review-cache.ts`
+`ReviewInputHashOptions`). The block is derived from the previous result, so
+including it would change the hash the moment a first review exists and miss on
+every re-review — disabling the cache exactly where it pays. A hit already means
+the diff, files, config and metadata are byte-identical, so reusing that run's
+conclusions is precisely what the block would have told the model to do.

Nothing validates the order — reversing it silently changes which config applies to already-routed files [inferred: no code checks that the `**/*` catch-all comes first, so reversing it silently changes routing].
 
 **`scope-config.jsonc` deliberately omits `auth` and `commentTag`.** It is a *different* template from the root `config.jsonc`, not a copy. A scope config carries no `auth` block — credentials are root-only, and the loader plus the CI guard reject a scope config that declares one [observed: `templates/scope-config.jsonc:1-3`; `AGENTS.md:51`]. It also omits `commentTag`, because a scope's PR-comment marker is always derived as `<rootTag>:<scope-name>` so `ecr ci` and `ecr review --scope --post` target the same comment; declaring one is rejected by the scope schema [observed: `templates/scope-config.jsonc:23-25`]. Reusing the root `config.jsonc` template for a scope — a tempting "simplification" — would break the trust boundary (LLP 0006).

+ * Two problems made this necessary, and both are structural rather than

+ *    redirects five times costs 60s, and a four-provider search walking its
+ *    candidates costs minutes. The deadline has to live here.
+ *  - The audit reserved one budget unit per tool call and reported nothing about
+ *    what that unit spent. One call can issue four paid searches and sixteen page
+ *    downloads, so "8 calls" understated real traffic by more than an order of
+ *    magnitude.

+// @ref LLP 0013#one-package-two-binaries [implements] — the environment boundary the engine's MCP config cannot provide
+/**
+ * Environment boundary for the bounded documentation MCP.
+ *
+ * ECR declares a minimal `env` in the engine's MCP configuration, but neither
+ * engine treats that as a replacement: Claude Code and OpenCode both MERGE it
+ * onto the environment the engine already holds. Verified by spawning each
+ * engine against a probe MCP that records variable names — the child saw the
+ * engine's model credential on both, and OpenCode additionally passed through
+ * the runner's whole ambient environment.
+ *
+ * So the boundary has to be ours. The engine spawns this wrapper; the wrapper
+ * spawns the real server with an environment it CONSTRUCTS. Whatever the engine
+ * merged in reaches this process and stops here.
+ *
+ * This file deliberately does almost nothing. It loads no HTML/JSON parser and
+ * opens no socket, because it is the one process in the chain that still holds
+ * the engine's credentials. Everything that touches untrusted remote content
+ * runs in the child, which never receives them.
