[ecr] make Jev an active verification cascade

One .expo-agents/ directory now holds every Expo agent tool's per-repo
files (this tool's and @expo/verify's) instead of one root dot directory
per tool. Every lookup — root, scopes, the config-file sweep, the reference
index, the .runs log — takes the new name first and falls back to the
legacy .expo-code-review/, and ecr init reuses an existing legacy directory
rather than doubling it. The CI templates upload reviews.jsonl from either
location. This repo's own setup dir moved.

+# 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+- No GraphQL thread resolution, and no detection of author-resolved/outdated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/config/schema.ts`, `src/config/load.ts` — `inline` key + lock + defaults.
+- `src/core/deferred-review.ts` — fingerprint includes `inline`.
+- `src/reporters/github.ts` — review-comments fetch (shared cache), syncInline

+- `src/commands/ci.ts` — wire config, `couldNotComplete: true` on both failure
+  literals, aggregate teardown flag. `review.ts`, `post-review.ts`,

 This is the root map for `@expo/code-review-cli` (`ecr`). It records what the system does, how the subsystems divide, the invariants that hold across all of them, and where each concern's rationale lives. It is intentionally thin: every subsystem's detail belongs in the doc that owns it. Read this first, then follow the link for the part you care about.

 `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]. Optional Jev aggregate usage is a second log sink; individual suppressions use the ordinary `verifierDropped` audit trail, and neither contains extra source text.
+
 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.

+Muse Spark uses the existing OpenCode engine, but OpenCode `1.18.4` does not ship a
+resolvable `meta` provider. `buildOpencodeConfig` therefore synthesizes one only for an
+in-use `meta` API-key entry without an `upstream`; an entry with `upstream` remains an

+destination is fixed to `https://api.meta.ai/v1`, its credential is an environment
+interpolation (never the key value), and its adapter is `@ai-sdk/openai` so requests use
+the Responses API and preserve encrypted reasoning across tool turns. The generic

+reasoning inclusion from `META_MUSE_MODELS`; a future id such as `meta/muse-foo` is
+declared with neutral metadata rather than guessed capabilities. This deliberately

 ## Claude Code CLI Containment
 
 The Claude Code engine runs each review pass as a single stateless

-environment are built to keep an untrusted PR (the review input) from turning that
-subprocess into code execution or credential exfiltration.
+`claude -p --output-format stream-json --verbose` subprocess fed the task on stdin.
+The JSONL stream makes tool activity observable while the pass runs instead of leaving
+only a periodic heartbeat until the final result. The incremental decoder emits only
+bounded lifecycle metadata and read-tool names with confined repo-relative targets;
+raw assistant text, tool results, grep patterns, and attempted host paths never reach
+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
+never copied into logs, and only an explicit final-result error message reaches
+provider-error classification. Every task-specific progress line is tagged with the
+stable agent bucket by the review pipeline, so concurrent passes remain attributable
+[observed] `claude-code.ts` `claudeExitDiagnostic`/`runClaudePrompt`, `review.ts`

+are built to keep an untrusted PR (the review input) from turning that subprocess into
+code execution or credential exfiltration.
+
+Every production structured-output parser carries a draft-07 JSON Schema generated
+from the same Zod contract used at the local trust boundary. The Claude runtime passes
+that schema through `--json-schema`; Claude Code validates the final `StructuredOutput`
+tool call and re-prompts inside the original session when a required field or type is
+wrong. The validated `structured_output` object is then serialized through the local
+Zod parser again — provider validation improves reliability but never replaces local
+validation. If Claude exhausts its in-session structured-output retries (or claims
+success without returning `structured_output`), the runtime makes one clean-process

+## Prior-Review Context
+
+A re-review used to start from nothing. Every pass ran stateless, so the reviewer
+could not tell a second push from a first look, and a finding a maintainer had
+already dismissed came back on the next run in slightly different words — near-
+identical repeats are caught by fingerprint suppression, a reworded re-raise is
+not.
+
+The state to fix that was already in hand. `ReviewState` round-trips the whole
+previous `CoordinatorOutput` — every finding with its file, line, severity and
+category — plus `dismissed`, `feedback` and `pins`, through the reviewer's own PR
+comment on every run [observed] (`src/core/render.ts:ReviewState`). It was
+decoded each run and consulted only afterward, for suppression and reply
+matching. `summarizePriorReview` reduces it to a bounded list, and
+`priorReviewSection` renders that as one fenced block for the reviewer and
+cross-cutting tasks [observed] (`src/core/prior-review.ts`,
+`src/core/prompts.ts:priorReviewSection`). Both CI paths supply it: the
+single-scope run reads the reviewer's comment once and reuses that read for the
+cache check, and a routed run resolves it per scope — from the scope's own comment,
+or, in `single` mode, from the aggregate's `scopes` entry paired with the root's
+dismissal records, keyed by the scope-namespaced fingerprint those records use
+[observed] (`src/commands/ci.ts` `scopePriorReview`).
+
+Carrying status is the part that earns the block. A maintainer's dismissal and an
+author's reply both happen *after* a run ends, so no amount of engine session or
+transcript replay could ever contain them; this channel is the only one that can.
+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]

+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.

+
+## 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.

+
+`@expo/code-review-cli` ships a documentation-search MCP as a second binary in
+the same npm package. ECR exposes that bounded MCP directly to reviewer and cross-file
+passes. Those agents decide when an external contract needs evidence, search for a
+precise symbol, or fetch an exact supported documentation URL already present in the
+review context. Coordinator, verifier, stack-verifier, and no-tools fallback passes do
+not receive the MCP.
+
+## 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, and ECR caps calls, results, and per-call duration. Each run
+uses an owner-only temporary MCP configuration and append-only audit. A tool failure
+remains local to research and never skips or weakens an ordinary review pass.
+
+The environment ECR declares in that configuration is a request, not a boundary. Both
+Claude Code and OpenCode merge a server's `env` onto the environment they already hold
+rather than replacing it, so the declared allowlist alone leaves the engine's model
+credential in the child — and under OpenCode the runner's entire ambient environment,
+because the SDK spawns its server with an unfiltered `process.env`. ECR therefore does
+not rely on the engines for this. The command in the configuration names a wrapper that
+rebuilds the environment from an explicit allowlist and then starts the real server.
+The wrapper is deliberately inert: it loads no parser and opens no socket, so the one
+process that still holds the engine's credentials is not the one that parses untrusted
+remote documents. Anything the engine merged in stops there.
+
+Starting a review does not derive searches from the patch, prefetch documentation, or
+start a crawl. ECR only prepares the bounded MCP configuration and audit path. Reviewer
+and cross-file agents make individual search or direct-fetch calls when their reasoning
+identifies an external contract that needs grounding. This keeps query selection inside
+the pass that understands the candidate issue and avoids spending calls on speculative
+identifier searches.
+
+## 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 the fixed `BRAVE_SEARCH_API_KEY` is the only
+credential the wrapper admits into the server's environment. Search titles, snippets,
+and ranking are untrusted discovery hints, never evidence.
+
+One reserved call is not one request. A search selects up to four providers, each of
+which issues its own discovery request and then downloads candidate pages until it has
+enough results, and every page may cost up to six round trips through the redirect
+chain. The call budget alone therefore understates outbound traffic by more than an
+order of magnitude, so each call carries a ledger — discovery requests, page fetches,
+redirect hops, total requests, elapsed time — recorded in the audit and summed for the
+review. The same seam carries one end-to-end deadline per call, because no engine can
+supply it: OpenCode's `mcp.timeout` bounds tool discovery rather than execution, and
+Claude passes no per-call timeout at all, leaving only a per-hop limit that multiplies
+instead of bounding. A call that reaches its deadline returns the evidence it already
+has rather than failing.
+
+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.
+
+Search-time page retrieval is demand-driven rather than a background prefetch. The
+MCP fetches the highest-ranked allowlisted candidates in batches sized to the number
+of results still needed. It advances to later candidates only when an earlier page is
+rejected, unavailable, or excluded by a requested language. Candidate pages that are
+not needed to fill the result limit are not downloaded.
+
+## 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 normalized extracted text—never raw HTML or DocC JSON. An optional query
+selects context within the page; it cannot turn the operation into discovery.
+
+Direct fetch uses progressive disclosure. `focused` returns a small contiguous group
+around the best passage. `section`, the default, returns at most 12,000 contiguous
+characters around that match. `document` returns at most 20,000 extracted characters
+and is reserved for contracts spread across a page. Every response reports the
+extracted document length, returned length, truncation, anchor passage id, and a
+bounded passage-id inventory. Search passages carry adjacent ids so a reviewer can
+recognize missing local context and expand the canonical URL instead of broadening
+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.
+
+There is no offline index, and no crawler to build one. Live discovery replaced the
+deterministic prefetch it was designed for, and the fallback it provided was never
+free: an index is an artifact whose bytes sit outside the trust boundary the rest of
+the system establishes. `research.indexPath` had to be an absolute path, so it
+resolved against the runner's filesystem rather than the materialized trusted base —
+the trusted-base mechanism protected the config that NAMED the index, never the
+contents at that path, and nothing carried a digest. Index passages were also the one
+evidence source returned unbounded, while every live source is length-capped.
+
+Removing it deletes that whole class of question rather than answering it. Every
+passage a review sees is now fetched during that review from an allowlisted host,
+bounded on entry. A config still naming `research.indexPath` fails to parse, so a
+stale setting surfaces as an error instead of being silently ignored.
+
+This also removes the reason researched reviews could not reuse a cached result.
+Reuse was disabled whenever research was enabled because evidence depended on mounted
+index contents that the cache key could not represent; with no mounted artifact, the
+ordinary input hash covers the whole review again.
+
+## Query and Prompt Boundary
+
+Reviewer prompts and MCP tool metadata tell direct clients to use exact symbols plus
+one member, behavior, or constraint term, and to retry a broad result with at most one
+narrower query. The MCP then deterministically removes quoted literals, URLs, email
+addresses, paths, prose stop words, overlong or high-entropy tokens, and unsupported
+punctuation. Credential-shaped or secret-labeled input fails closed. The remaining
+query must contain an API-like symbol — which includes hyphenated package names such
+as `expo-camera` — or be a short multi-word lowercase concept phrase, stay under eight
+short tokens, and fit the review-wide call budget. The concept-phrase allowance exists
+because guide, release-note, and Expo topics frequently have no CamelCase symbol; its
+tokens pass the same length, entropy, and secret checks, and a single generic word
+still fails closed. The search tool's advertised result limit is derived from the
+enforced per-call bound, and the direct-fetch focused passage count is independent of
+that bound, so a caller's mental model matches what a request can return.
+
+Provider selection preserves native platform ownership. Swift or Objective-C source
+uses Apple for OS contracts; Kotlin, Java, and Gradle source uses Android for platform
+contracts. Explicit library signals add the owning provider—such as SDWebImage,
+Media3, Glide, or OkHttp—when library behavior also matters. Repository ownership is
+not documentation ownership, so a `packages/expo-*` path does not replace Apple or
+Android with Expo documentation.
+
+These checks bound the SHAPE of an outbound request, not its information content. The
+reviewing model reads repository data and then chooses the query terms and URL path,
+and a token that satisfies every rule above — short, low-entropy, API-shaped — can
+still encode repository-derived bytes. The provider allowlist fixes who receives a
+request; it does not constrain what the request says. Research is therefore an
+outbound disclosure channel to Brave and the documentation providers, appropriate only
+where repository-derived terms may be shared with them, and the reviewer prompt's
+instruction not to send repository text is a mitigation rather than an enforcement.
+
+MCP output is schema-validated, limited to HTTPS URLs from the requested provider,
+truncated, and sanitized. Returned passages are labeled untrusted reference data in
+the reviewer prompt. The Brave credential is scoped to the MCP child and 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 unbounded 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.
+
+Calls refused before execution are also audited, by reason class only: a rejected
+query, a rejected direct-fetch URL, or an exhausted call budget. The refused input is
+never recorded — it may be exactly the material the sanitizer refused to send — but
+the counts surface in progress output and the step summary so operators can see unmet
+research demand and tune the budget. A budget-exhausted attempt does not consume a
+reservation.
+
+The reviewer may select a source for a finding only by copying its exact title and URL
+from an MCP result. Model output crosses an engine-side grounding seam: URLs absent
+from the run's append-only MCP audit are removed and accepted titles are restored from
+canonical evidence. URL matching is fragment-insensitive — a model that normalizes a
+copied URL by dropping its `#fragment` keeps its citation, and the audited URL (never
+the model's variant) is what gets restored. 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 research omit them.
+
+A finding that cites research always reaches the adversarial verifier, and its task
+inlines the audited passages behind those citations as fenced untrusted reference
+data. The repository alone cannot confirm an external-behavior claim, so without the
+passages the verifier would judge it from model memory — the failure mode research
+exists to remove. The verifier separately reports whether the cited passages support
+the claim; an explicitly unsupported citation is stripped (including its
+fingerprint-carried copy) while the finding itself still stands or falls on the
+ordinary verdict, and any ambiguity fails open toward keeping the citation.
+
+A reviewer may also emit a bounded, conclusion-only `researchDecisions` record when
+documentation materially confirms a finding candidate or proves one safe. These
+records never enter policy or decision logic. ECR discards any record without an exact
+audited source. After verification and suppression produce the final findings, ECR
+counts final cited findings, supported and dismissed candidates, and unique result
+URLs materially used versus unused. A narrow heuristic also counts final findings that
+assert external platform behavior — a version or API-level claim, or
+documented-lifecycle wording — with no grounded citation; the count is advisory
+observability, never a gate. The Actions summary displays those metrics and grounded
+candidate conclusions; the JSONL run record preserves the same structured data with
+the queries and bounded results.
+
+## Installation-Specific Research Is Deferred
+
+The built-in source catalog covers Apple, Android, platform releases, Swift
+Evolution, SDWebImage, Media3, Glide, OkHttp, Kotlin coroutines, Gradle/AGP, selected JetBrains
+issues, Expo, React, React Native, WHATWG and W3C web specifications, Chrome DevTools
+Protocol, Flow, TypeScript, the Android NDK, CMake, CocoaPods, Metro, Reanimated,
+Gesture Handler, Screens, and Worklets. The React Native
+additions cover the contracts its implementation must preserve: React semantics, its
+web-compatible APIs, the repository's type systems, and its native build and dependency
+managers. Hermes documentation is intentionally not fetched from the engine's `main`
+branch because it can disagree with React Native's vendored revision. Repository PR and
+issue history is intentionally not a
+live evidence provider: it belongs in a versioned offline evaluation corpus used to
+improve prompts, while the runtime MCP remains an API-contract channel.
+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.

+Jev is a discriminative model from TypeSafe AI. It answers typed questions over
+provided state and returns a probability distribution; it does not browse a repo,
+discover open-ended defects, explain causality, or write remediation. ECR therefore
+uses Jev inside verification, after generative reviewers have produced findings.
+
+## Decision
+
+ECR uses an active `generate → classify → defer` cascade. Jev is neither a shadow
+observer nor another general reviewer agent:
+
+1. generative reviewers discover and explain candidate defects;
+2. deterministic code confines paths and grades quoted evidence;
+3. Jev makes one atomic local support judgment per finding;
+4. high-confidence support keeps the finding, while high-confidence contradiction
+   drops only ordinary correctness/quality findings;
+5. uncertainty and protected findings defer to the existing reasoning verifier.
+
+Adding the root `jev` config activates the cascade. There is no separate `enabled`
+flag and no shadow phase. If the config, credential, or a usable response is absent,
+the finding follows the pre-Jev verification rules.
+
+## Evidence Survey
+
+The primary implementation sources are TypeSafe's [Jev announcement](https://typesafe.ai/blog/introducing-system-one-models-and-jev),
+[System One guide](https://docs.typesafe.ai/concepts/how-to-build-with-system-one),
+[confidence guidance](https://docs.typesafe.ai/confidence),
+[confidence-routing pattern](https://docs.typesafe.ai/patterns/confidence-routing),
+[citation-check cookbook](https://docs.typesafe.ai/cookbooks/citation_check),
+[software-development cascade](https://docs.typesafe.ai/cookbooks/sde_cascade),
+[Jev 1.13 model notes](https://docs.typesafe.ai/model-jaggedness/jev-1.13), and the
+open-source [JavaScript SDK](https://github.com/typesafe-ai/typesafe-sdk-js).
+
+The consistent vendor guidance is to keep deterministic control flow in code, ask
+narrow independent questions over relevant state, act only above a risk-appropriate
+confidence threshold, and route uncertain results to a stronger reasoner. Confidence
+measures concentration of the answer distribution, not factual correctness. Jev is
+also documented as weak on arithmetic, counting, dates, complex indirection, and
+irrelevant context. These limits rule out using it as the only verifier.
+
+The architecture also follows older work on selective prediction and abstention:
+[SelectiveNet](https://proceedings.mlr.press/v97/geifman19a),
+[Learning to Defer](https://proceedings.mlr.press/v119/mozannar20b.html),
+[Calibrated Learning to Defer](https://proceedings.mlr.press/v162/verma22c.html), and
+[Language Model Cascades](https://arxiv.org/abs/2207.10342). Their shared idea is
+that a useful classifier should act on its competence region and reject or defer the
+rest. [Generative Verifiers](https://openreview.net/forum?id=Ccwp4tFEtE) further
+supports retaining a generative verifier for multi-step reasoning rather than treating
+a discriminative score as universal proof.
+
+Code-review-specific evidence argues for conservative authority. Research on
+[LLM code-review overcorrection](https://arxiv.org/abs/2603.00539),
+[security code review](https://arxiv.org/abs/2401.16310), and
+[judge calibration and bias](https://aclanthology.org/2025.acl-long.808/) shows that
+binary judgments can be confidently wrong and that security claims need stronger
+grounding. Vendor benchmarks measure agreement with other model outputs rather than
+human-adjudicated ECR findings, so they establish speed and structured behavior, not
+an acceptable false-negative rate for this repository.
+
+The useful philosophical analogy is dual-process reasoning: Jev supplies a fast,
+bounded System 1 judgment; the tool-using verifier supplies slower System 2 analysis.
+The relevant engineering principle is a reject option, not majority voting. Jev's
+different model family adds diversity, but agreement between two models is not ground
+truth and disagreement is a reason to inspect, not to average blindly.
+
+## Active Selective Cascade
+
+The policy is intentionally asymmetric:
+
+| Jev result | Ordinary correctness/quality | Critical, security, secrets, or cited |
+| --- | --- | --- |
+| supported at or above threshold | keep | cited findings defer; other protected findings keep |
+| contradicted at or above threshold | drop with an audit reason | defer to reasoning verifier |
+| `needs_reasoning` or low confidence | defer to reasoning verifier | defer to reasoning verifier |
+| missing response or provider failure | use original verification path | use original verification path |
+
+“Protected” controls the dangerous direction: Jev may help retain such a finding, but
+cannot suppress it alone. Cited findings always defer because Jev receives repository
+source, not the audited external passage whose support must be checked.
+
+The default `minConfidence` is `0.9`. It is a conservative operating point, not a
+claim of 90% correctness. Repositories may change it explicitly, but model version,
+question text, state shape, threshold, and truncation policy form one classifier and
+must be reviewed together. A dated model is preferred over a moving alias.
+
+## State and Security Boundaries
+
+Each request includes finding category, severity, file, line, title, rationale, and
+quoted evidence plus bounded source from that file. ECR sends no PR title/body,
+unrelated file, agent transcript, author reply, or credential. `maxContextChars`
+bounds disclosure and context rot; truncation centers on the quoted evidence where
+possible. Four requests run concurrently, with a bounded timeout and one retry.
+
+The API origin is explicit. Ambient TypeSafe URL/model variables cannot redirect the
+request. SDK logging is off because bodies contain source. `TYPESAFE_API_KEY` is
+captured before reviewer startup, withheld from OpenCode, and forbidden as a reviewer
+provider credential. Paths remain confined to the materialized review tree before
+any source is read.
+
+Jev is not a prompt-injection detector or security boundary. The code and finding
+text are attacker-controlled inputs, and model output is schema-validated before the
+policy sees it. Deterministic code continues to own credential isolation, path
+confinement, evidence matching, category floors, and final decision derivation.
+
+## Failure and Observability
+
+The cascade fails back, not closed. Missing credentials disable only Jev for that run.
+An individual timeout, malformed response, or provider error sends that finding
+through the original verification path. Error text is not persisted because providers
+may echo source. The run log stores aggregate model, duration, token, cost, evaluated,
+and failure counts; any finding dropped by Jev appears in the ordinary
+`verifierDropped` audit trail with its confidence.
+
+Published pricing for the pinned integration is $0.042 per million input tokens with
+no output-token charge. Cost is recorded in the `jev-verifier` bucket. Provider limits
+are not treated as local capacity guarantees.
+
+## What Jev Replaces
+
+Jev replaces only straightforward finding verification calls. It does not replace:
+
+- reviewer agents that discover bugs and supply explanations;
+- the coordinator that merges and prioritizes findings;
+- deterministic evidence, trust, and security checks;
+- the reasoning verifier for ambiguity, multi-file behavior, runtime semantics,
+  citations, or protected negative judgments.
+
+This division gives Jev real authority and cost benefit without pretending that a
+fast typed classifier is a complete code reviewer.
+
+## Rejected Alternatives
+
+**A standalone `jev.md` reviewer agent.** Jev cannot use ECR's browsing tools or emit
+the finding schema's explanation and remediation. Presenting it as a peer reviewer
+would hide a different and narrower capability behind the same abstraction.
+
+**Shadow-only operation.** It adds latency and cost without improving the review. The
+safe boundary comes from abstention, protected categories, and fallback behavior, not
+from making every result inert.
+
+**Replace all verification.** Local classification cannot resolve missing repository
+context, multi-step execution, arithmetic, temporal behavior, or external citations.
+
+**Use confidence as proof.** A concentrated distribution can still be wrong. The
+threshold is a routing policy and protected contradictions still require reasoning.
+
+**Send the entire diff or repository.** Unrelated context increases disclosure and
+context rot. One bounded file is the smallest state that supports the local question.
