fix: label a run that reviewed nothing "No review", without claiming why

The label said "No review — every pass failed", but the same flag also marks
CI runs that failed or stopped before any pass ran, so the reason was often
wrong. The summary under it already says what happened.

+  as they are.
+- The reviewer recognises its labels by login, from the label's newest
+  `labeled` or `unlabeled` event on the PR. It removes the label only when its
+  own login added it last, and does not add it again when another login removed
+  it last. Its login is `gh api user` for a personal token, or GraphQL `viewer`
+  for an installation token (the default `GITHUB_TOKEN`, `github-actions[bot]`, or
+  a GitHub App's, `<app>[bot]`); when both fail under GitHub Actions it assumes
+  `github-actions[bot]`. So:
+  - With a personal token, that person's own removals count as the reviewer's,
+    and the next ready review adds the label again.
+  - Under the default `GITHUB_TOKEN`, other workflows' label changes are
+    `github-actions[bot]` too, and count as the reviewer's.
+  - A local `ecr review --pr <n> --post` and CI use different logins, so neither
+    removes a label the other added.
+  - On a PR with 3,000 events or more, the reviewer cannot tell who changed the

 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].
 
+A reviewer pass may also return a `summary`: one or two sentences on what it reviewed and concluded, for the human readers of the comment. The parser fails soft in the same way as the trace, flattens the text to one line, and cuts it at 280 characters. `runReview()` keeps up to two distinct pass summaries per agent, so a chunked agent reports each part; they are the first two in diff order, not in the order the passes finish, so the same run always keeps the same parts. The parts are keyed in a `Map`, so an agent id such as `constructor` cannot read an inherited property. `buildAgentSummaries` turns them into one row per roster agent: the agents that ran (each once, even an agent whose id collides with the cross-file pass's `cross-cutting`), in run order and with the cross-cutting pass last, then the agents that did not run, marked `paths` (the run-level `paths` filter skipped them) or `router` (the router did not select them). An agent that ran but returned no summary keeps its row without text. Over the 8 KB budget, the last rows lose their text but keep their place. `attachAgentSummaries` attaches the list to `CoordinatorOutput.agentSummaries` at the same point as the trace and for the same reason: the coordinator reads untrusted PR data, so it can never author the field. The summaries never reach coordination, verification, suppression, or the decision [observed: `schema.ts` `ReviewerOutputSchema`/`AgentSummarySchema`; `review.ts` `mergeAgentSummary`/`buildAgentSummaries`/`attachAgentSummaries`].
+
+A pass may also return `humanReview`, one sentence on why a person should review the change, parsed and cut like the summary. `runReview()` keeps the first reason per agent. `buildMentions` turns a reason into a mention only for an agent that ran and whose front matter has a `mention` list, and the people come from that list, never from the model. `attachMentions` attaches the result to `CoordinatorOutput.mentions` with the other engine-owned fields and strips any coordinator-authored value. A mention never affects the decision or the finding set [observed: `review.ts` `buildMentions`/`attachMentions`].
+
 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.

 Two more grounding rules follow from the same caution:

 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`].
 
+The engine-owned `agentSummaries` live in `review` for the same reason, but they are rendered: a collapsed "🔎 Reviewer summaries" section under the overall summary (and under each scope's summary in the aggregate comment) lists one line per roster agent, with its summary, "no summary", or why it did not run. Summaries are model text that reaches the visible body, so `plainModelLine` strips formatting tags, escapes the `&` of every HTML character reference that spells `@` (GitHub decodes `&#64;` or `&commat;` before it looks for mentions; a reference after the `@` needs nothing, since that `@` is broken anyway), escapes every `<` (which also defuses a forged state marker), collapses the text to one line, and puts a zero-width space after every `@` that does not follow an ASCII letter or digit, so a summary can never notify a GitHub user or team. The rule is deliberately broader than GitHub's own (which needs a non-word character before the `@`): markdown starts a new text node at punctuation such as `_`, so `_@login_` renders as `<em>@login</em>` and notifies, and only a letter or digit before the `@` is safe to trust, which keeps an email address whole [observed: `render.ts` `agentSummariesSection`/`plainModelLine`].
+
+The engine-owned `mentions` are the one place a review notifies people on purpose (the `/dismiss` and reply credits only name the person who acted). Each renders as a visible `> 📣 @login: the \`agent\` reviewer asks for your review.` line above the summaries section, followed by the agent's reason through `plainModelLine`. In the aggregate comment the line sits inside its scope's fold, so a request opens that fold like a finding does. Every other piece of model text that reaches a comment, the summaries and each finding's title, rationale, suggestion, source titles and requalification reason, goes through `modelText`, which escapes `@` character references and breaks each `@` by the same rule as the summaries while it keeps the text's lines and formatting; so do the inline finding comments [observed: `render.ts` `modelText`/`breakMentions`]. The renderer checks every login against `MENTION_TARGET_RE` again, because a re-render reads the state back from the comment body. The reporter edits the comment in place on later runs. GitHub documents that an edit which adds a mention notifies that person, so a mention that first appears on a re-review still notifies [observed: GitHub Docs, "Basic writing and formatting syntax", mentioning people and teams; `render.ts` `mentionLines`].
+
+That same rule would notify a person again each time a request returns: `humanReview` is model output recomputed on every run, so it can drop out on one push and come back on the next. The comment state therefore carries `mentioned`: the handles the body mentions for real (`live`) and every handle the comment has ever notified (`notified`). A handle stays live while it stays in the comment, and one that left and came back renders with a zero-width space after its `@`, so the line still names the person without notifying them. `report`, `reportAggregate` and the `/dismiss` re-render all pass the previous state's `mentioned` back in. A comment the bot deletes (`clear()`) and posts again starts with no state, so it notifies again [observed: `render.ts` `nextMentionState`; `reporters/github.ts`].
+
 ## 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.

 ## Truncation and Aggregate State
 
-`renderAggregateMarkdown` folds multiple monorepo scopes into one comment under the single marker. GitHub's body limit is treated as ~65k chars and the renderer keeps a margin at `MAX_COMMENT_CHARS = 60_000` (`render.ts:316-317`). When a body overflows, it trims each scope's KEPT findings to the most-severe N, halving until it fits with a floor of 3 (`render.ts:480-489`). The first truncation step seeds N from `largestScope / 2` rather than an arbitrary constant, so it lands close to the needed size in one step instead of wasting iterations.
+`renderAggregateMarkdown` folds multiple monorepo scopes into one comment under the single marker. GitHub's body limit is treated as ~65k chars and the renderer keeps a margin at `MAX_COMMENT_CHARS = 60_000` (`render.ts:316-317`). When a body overflows, it first leaves out every scope's `agentSummaries`, from both the visible rows and the embedded state, with a one-line note in each scope that had them. Each scope's summaries fit their own 8 KB budget, but nothing bounds the sum across scopes, and they never affect the decision, so they go before any finding. The single comment has no findings trim, but it applies the same first step: escaping (`<` becomes four characters) and the base64 state copy make the summaries several times their byte budget, and a body over GitHub's limit fails to post, which would replace a finished review with the failure notice. Summaries left out this way are gone from the state, so a later `/dismiss` or cache reuse renders without them. If the aggregate body still overflows, it trims each scope's KEPT findings, halving until it fits: first the findings with a live inline thread, which keep their thread on the PR, then the others to the most-severe N, with a floor of 3 per scope in total. Once it fits, it raises both limits back by binary search to what still fits, and if the floor itself does not fit it goes below it, since a body over GitHub's limit is not posted at all (`renderAggregateMarkdown`, `largestFitting`; see [LLP 0008](./0008-sources-and-reporters.explainer.md#inline-threads)). The first truncation step seeds N from `largestScope / 2` rather than an arbitrary constant, so it lands close to the needed size in one step instead of wasting iterations.
 
 The invariant that makes this safe: **dismissed findings always survive in full in the embedded state, regardless of truncation** (`render.ts:449-459`). Truncation trims only the shown/kept set; the state blob still carries every dismissed finding so `/undismiss` never permanently loses a dismissal (`render-aggregate.test.ts:117-137`). An agent "simplifying" truncation to also drop dismissed entries would break `/undismiss`.
 
-The state blob is deliberately dual-shaped: it keeps a synthesized v1-shaped `review` field (a merge across scopes) beside the real per-scope `scopes` field, so older consumers expecting the pre-routing v1 shape keep parsing while v2 consumers read real per-scope data (`render.ts:293-300`, `render-aggregate.test.ts:88-103`). `renderSeveritySections` is the single shared display path for both the single-comment and aggregate renderers, with `SEVERITIES`/`SEVERITY_RANK` as the sole ordering source of truth, so the two renderers cannot drift.

Every render path reads a finding's severity through `knownSeverity`, because the embedded state is not schema-validated on read and a newer engine can store a severity this one does not know (`design` and `nit` crashed the grouping in older engines on `/dismiss` and on a partial `--scopes` re-render). An unknown value renders as a `warning`, and the stored value is kept so the newer engine reads it back unchanged. This only protects engines from this version on.

 ## GitHub Reporter Identity
 
-The reporter maintains exactly one PR comment and is comment-only — it never touches the review-thread / GitHub "reviews" APIs, by explicit design [observed] ([github.ts:77-82](../src/reporters/github.ts)). The hard problem is: which comment on the PR is *ours*?
+The reporter maintains exactly one PR comment, plus optional inline threads (see [Inline Threads](#inline-threads)), and it never approves or requests changes: the only review it creates is a `COMMENT` review that carries a run's new inline threads [observed] ([github.ts](../src/reporters/github.ts) `GitHubReporter` doc comment). The hard problem is: which comment on the PR is *ours*?
 
 **Author + marker, never marker alone.** The comment marker is a hardcoded public literal, readable in the base-branch config, so anyone who can comment on the PR (including the untrusted PR author) could post a comment carrying the marker plus a forged embedded review state. A newest-marker-wins lookup would adopt that state and carry its `dismissed` list forward, silently suppressing real findings. So a comment counts as ours only if it carries the marker AND was authored by `ownLogin` — GitHub sets a comment's author from the authenticated identity and it cannot be spoofed [observed] ([github.ts:51-75](../src/reporters/github.ts); commit 93aaf30: "identify our own comment by author + marker, not the public marker alone, so a forged comment can't carry review state forward"; regression tests `src/__tests__/github-reporter.test.ts:25-34`). Any rewrite that reintroduces marker-only matching reopens this forged-dismissal-state attack.
 
-**Fail closed on unresolvable identity.** `resolveOwnLogin` tries `gh api user --jq .login` first (works for a user/PAT token), and falls back to the literal `github-actions[bot]` only under GitHub Actions, because the default `GITHUB_TOKEN` is an installation token for which `/user` returns 403 [observed] ([github.ts:91-117](../src/reporters/github.ts)). When neither resolves, `ownLogin` is `null` and `selectOwnComments` treats NOTHING as ours [observed] ([github.ts:69-71, 114](../src/reporters/github.ts): `if (!ownLogin) return []`; test `github-reporter.test.ts:46-50`). It does not degrade to marker-only matching; it refuses to claim anything.
+**Fail closed on unresolvable identity.** `resolveOwnLogin` tries `gh api user --jq .login` first (works for a user/PAT token). An installation token, the default `GITHUB_TOKEN` or a GitHub App's, gets 403 there, so it next asks GraphQL for `viewer { login __typename }`, which GitHub documents for installation tokens; `viewerRestLogin` accepts only a Bot, since only an installation token gets that far, and adds the `[bot]` suffix REST uses for comment authors and event actors when GraphQL leaves it off [not verified live]. Only when both fail does it fall back to the literal `github-actions[bot]`, and only under GitHub Actions ([github.ts](../src/reporters/github.ts) `resolveOwnLogin`, `viewerRestLogin`).

It does not degrade to marker-only matching; it refuses to claim anything.
 
 **Full-tag marker matching.** `<!-- tag -->` is checked as a whole tag, not as a substring, so a root marker and a scoped marker `<!-- tag:scope -->` cannot cross-match — this is the "reviewdog #1911 lesson", a known bug class in other PR-comment tools where prefix-matching markers collide across scopes [observed] ([github.ts:180-185](../src/reporters/github.ts), citing the lesson verbatim). Deletion is scoped strictly to author-verified comments: `clear()` and the upsert's duplicate cleanup only ever delete comments returned by `selectOwnComments`, never a look-alike carrying the same marker from someone else [observed] ([github.ts:186-192, 351-366](../src/reporters/github.ts)).

 **Links fail soft.** `linkContextAsync` can be prebuilt and injected once so a CI fan-out builds one diff-lines + base-SHA context for all scopes instead of one pair of `gh` calls per scope — the reporter-side mirror of `memoizeSource` [observed] ([github.ts:33-37, 200-205](../src/reporters/github.ts)). Both underlying fetches fail soft: a missing diff index degrades in-diff findings to plain-text `file:line`, a missing base SHA degrades out-of-diff findings the same way — never a dead link, never a hard failure of the whole report [observed] ([github.ts:194-235](../src/reporters/github.ts); commits f9fecd5, 9446b42). This follows the repo rule that `ecr ci` must never fail a PR's checks on reviewer error [observed] (AGENTS.md: "`ecr ci` must never fail a PR's checks — reviewer errors degrade gracefully").
 
+**The ready label follows the decision, and the bot removes only its own.** With `review.readyForHumanLabel` set, `report` and `reportAggregate` call `syncReadyLabel` after the comment is posted, and `postSkipNote` and `clear` call it with "not ready". `postSkipNote` is `ecr ci`'s break-glass path only: `ecr post-review` and `ecr review --pr --post` post nothing on break-glass, and a PR the trigger policy skips returns before any reporter call, so those leave the comment and the label as they are. `ecr ci` also calls `removeReadyLabel` before it reviews new commits (a `pull_request` `synchronize` event, `isNewCommitsEvent`), so the label never describes a head no review has seen; the review adds it back if the new head is ready. With a personal or App token the removal is itself an `unlabeled` event that starts another run, which cancels this one under the scaffolded workflow's `cancel-in-progress` and reviews the same head; that run is not a `synchronize`, so it does not remove the label again. Label failures only log: the comment is already up [observed] ([github.ts](../src/reporters/github.ts) `syncReadyLabel`, `readyForHuman`, `lastLabelEvent`; tests `src/__tests__/ready-label.test.ts`).
+
+**Ready means the run reviewed the whole PR.** `readyForHuman` is true when every review completed with full coverage (`incomplete` is empty), at least one reviewer applied, and the worst decision is `approve` or `approve_with_comments`; `reportAggregate` also requires no unmatched files. A review where no agent's `paths` matches approves with every `agentSummaries` row `notRun`, so that is what "no reviewer applied" checks; `incomplete` stays empty there, and a noise-only review has no rows at all. A run that reviewed part of the PR sets the reporter's `partialReview`, and then `syncReadyLabel` treats it as not ready: an explicit `--agents` subset in `ecr ci` and `ecr review --pr --post`, a `--scopes` run, whose other scopes come from the comment's stored state without a check against the head, and a deferred review saved with `--agents`, which records `partialReview` in the artifact for `ecr post-review` to pass on. A bare `/review` lets the router pick agents and is a full run. Without `--scopes` every active scope gets a result, failures included, so no other check for missing scopes is needed ([ci.ts](../src/commands/ci.ts) `runLegacyCi`, `runRoutedCi`; [deferred-review.ts](../src/core/deferred-review.ts)).
+
+**Ownership comes from the label's own history.** The newest `labeled` or `unlabeled` event for the label (`lastLabelEvent`; the events API lists the oldest first) decides what is ours: a review that is not ready removes the label only when the newest event is our account's `labeled`, and a ready review does not add it again when the newest event is another account's `unlabeled`. No extra state is stored in the comment. The walk stops at the page cap; when it stops on a full page, a newer event may lie beyond it, so `syncReadyLabel` changes nothing and logs. "Our account" is `resolveOwnLogin` (see [GitHub reporter identity](#github-reporter-identity)). The check is by login, not by person: a personal token treats that person's own changes as ours, under the default token other workflows' label changes are `github-actions[bot]` too and count as ours, and a local `ecr review --pr --post` and CI run as different logins, so neither removes the other's label.
+
+**Only the single comment labels, and the label is advisory.** In per-scope mode there is no one decision for the PR, `ecr ci` logs that it sets no label, and the root-tag `clear` of a mode switch removes ours (`runRoutedCi` in [ci.ts](../src/commands/ci.ts)). `/dismiss` re-renders with the stored decision, so it does not change the label. Label names match case-insensitively, as GitHub treats them, and the config check rejects a label that is, in any case, also `review.label`, `review.skipLabel` or a `<label>:<agent>` trigger. The decision comes from model output on untrusted PR content (see [LLP 0001](./0001-trust-model.principles.md)), so the label is advisory, never a merge gate.
+
+## Inline Threads
+
+With `inline.enabled`, `syncInline` converges one inline thread per in-diff finding: `planInlineSync` decides which threads to create, patch, stub or delete, and the executor runs the plan [observed] ([github.ts](../src/reporters/github.ts) `planInlineSync`, `syncInline`).
+
+**One review per run for new threads.** GitHub makes every `POST /pulls/{n}/comments` its own review, so posting threads one by one put one "reviewed" entry and one notification per finding on the PR. The executor instead posts all of a run's new threads in one `POST /pulls/{n}/reviews` with `event: "COMMENT"`, the reviewed head as `commit_id`, and an empty body [observed] ([github.ts](../src/reporters/github.ts) `createInlineReview`). GitHub's docs call the body required for a `COMMENT` review, but it accepts an empty or missing one when the review has comments [observed: probe against a private scratch PR, 2026-10-21]. A submitted review can't be deleted, so a body would stay on the PR after its threads are torn down; an empty one leaves nothing. In per-scope comment mode every scope's reporter syncs its own threads, so a run posts one review per scope with new threads [observed] (`reporterFor` in `src/commands/ci.ts` passes the root `inline` config to each scope). Patches, stubs and deletes stay per comment: they edit existing threads and create no review.
+
+**The batch is all or nothing, and only a 422 a comment caused is retried.** GitHub rejects the whole review with a 422 when it refuses one comment, for example a line it will not anchor, and then creates nothing: a review with one valid and one unanchorable line came back 422 `Line could not be resolved` and created neither comment [observed: probe against a private scratch PR, 2026-10-21]. That error falls back to one `POST /pulls/{n}/comments` per thread, so only the refused comment is lost. Two 422s are about the account, not a comment, and one-by-one posts would hit them again: GitHub's spam throttle ("submitted too quickly") aborts the rest of the sync like a rate limit, for the review and for each one-by-one post, and a pending review the posting account already has on the PR (GitHub allows one, and refuses both POSTs with "one pending review per pull request" while it exists) fails the new threads with a message saying to submit or delete it, while stubs and deletes still run. Telling them apart needs the response body: `gh` prints only the top-level message to stderr (`gh: Unprocessable Entity (HTTP 422)`) and the body, with `errors[]`, to stdout [observed: probe against a private scratch PR, 2026-10-21; the spam throttle's text is from reports, not reproduced], so both POSTs run with `check: false` and `ghApiFailure` keeps the body's distinct messages, each capped, in the error. Any other failure, such as a 5xx or a dropped connection, may come after GitHub created the review, so a retry could post every thread twice: the executor counts those threads as failed and does not retry, the main comment renders the findings in full, and the next run creates whatever is still missing. A rate limit aborts the rest of the sync as before [observed] (`syncInline`, `isPendingReviewError`, `ghApiFailure`; tests `src/__tests__/inline-review.test.ts`).
+
+**Links come from a second call.** The review response does not list its comments, so the executor reads `GET /pulls/{n}/reviews/{id}/comments` a page at a time, up to the same 30-page bound as every comment listing, and maps each comment to its finding by the anchored marker in its body (`inlineUrlsByFp`). When a page fails, the pages before it stay linked, the threads exist, and the main comment renders the rest in full for this run; the next run finds the threads through `ownInlineComments` and links them. A rate limit on that read aborts the stubs and deletes still to come [observed] (`syncInline`, `inlineReviewCommentPages`).
+
+**The main comment does not repeat an inlined finding.** A finding with a live thread is read in that thread, so the main comment shows only its `id:`, linked to the thread, and its location, in one row per severity under `💬 Inline comments on the diff`, with a link to a reply when an author answered it. The id stays because `/dismiss` takes it and `/dismiss` is an issue comment, not a thread reply. The location stays because the fingerprint leaves out the line, so a finding whose line moved keeps its thread on the old line (`renderSeveritySections`, `splitInlined`, `inlinedLines` in [render.ts](../src/core/render.ts)).
+
+**A thread is live only when it shows the finding.** `syncInline` links a thread when its body already equals the finding's render or its update succeeded, and `/dismiss` and `/undismiss` read the threads before they render and apply the same rule to the stored finding. So a stub, a thread a failed or rate-limited update left showing older text, an outdated thread (GitHub returns `line: null` once its line left the diff, and the thread is collapsed), a finding outside the diff or over `maxComments`, and a failed link are all listed in full. A `/undismiss` restores a stubbed thread before it renders. With duplicate threads for one finding the newest counts, as in `planInlineSync`. When the threads can't be listed, every finding renders in full [observed] (`syncInline`, `applyDismissal` in [github.ts](../src/reporters/github.ts)). The rule cannot see a thread someone resolved, or one a person with write access deleted after the render; the next review run lists the latter in full again.
+
+**The size cap trims inlined findings first.** In the aggregate comment, every inlined finding is trimmed before any listed one: a trimmed inlined finding keeps its thread on the PR, while a listed one appears nowhere else. Inlined findings must still be trimmable, because each renders as one link but carries its full text in the embedded state. A scope with findings keeps at least 3 in total, inlined ones filling up to 3 when fewer are listed. Both limits are shared by every scope and halving overshoots, so once the body fits the renderer raises them again by binary search, inlined first, and a scope that fits whole keeps every finding and its input hash. If 3 large findings still do not fit, it goes below the floor rather than post a body GitHub rejects. A trimmed finding leaves the state, so `/dismiss` does not accept its id until a review run that fits, and the note under the scope says so (`renderAggregateMarkdown`, `largestFitting`; see [LLP 0005](./0005-verification-fingerprints-rendering.explainer.md#truncation-and-aggregate-state)).

 ## Terminal Reporter
 
 The terminal reporter writes the primary report to **stdout** (progress and logging go to stderr) specifically so `ecr review > out.txt` captures a clean report and shell redirection works as expected [observed] ([terminal.ts:45-47](../src/reporters/terminal.ts)). It maps `review.decision` to a process exit code via `decisionExitCode`, which is what makes it usable as a pre-push/pre-commit gate; `--json` disables color and `noFail` forces exit 0 [observed] ([terminal.ts:28-32, 38, 49](../src/reporters/terminal.ts)). Color is enabled only on a TTY and only when not `--json` [observed] ([terminal.ts:38](../src/reporters/terminal.ts): `!options.json && Boolean(process.stdout.isTTY)`) — naively coloring whenever output is not JSON, ignoring `isTTY`, would corrupt piped or redirected output with ANSI codes.

A config that still sets the boolean `includeSuggestions` loads with a deprecation note (a setup note on the review, a non-failing ⚠ in `ecr doctor`): `true` becomes `"nit"` and `false` becomes `"design"` [observed: `src/core/schema.ts` `SEVERITIES`; `src/core/review.ts` `applyReviewPolicy`; `src/config/load.ts` `resolvePolicy`].
 
 **Coordinator and security pin the pro tier on purpose.** The default agent model is `openai/gpt-5.5`, but `coordinator.md` and `agents/security.md` both pin `openai/gpt-5.5-pro` in their frontmatter [observed: `templates/config.jsonc:6`; `templates/coordinator.md:1-8`; `templates/agents/security.md:1-9`]. The rationale is stated in each file: the coordinator makes the final de-dupe/severity/decision call where "consolidation quality matters more here than the small serial-tail latency it adds," and security is "the highest-stakes agent," scoped alone to bound the extra latency/rate-limit cost [observed: `templates/coordinator.md:2-5`; `templates/agents/security.md:4-7`]. Downgrading either to save cost silently reverses that tradeoff, and no test catches it [inferred: no test asserts the coordinator/security model pins, so a cost-driven downgrade would go uncaught].

Conflating the two is the failure this prevents: a `Medium`-confidence secret leak and a `High`-confidence style nit are not comparable, and a single severity field cannot say so. `Low` confidence is not a rendering choice — it is a report threshold, and the coordinator drops those findings outright [observed: `templates/shared.md:119-120`; `templates/coordinator.md:28-36`]. The coordinator also folds any `suggestion` into a `**Suggested remediation:**` line inside `rationale` and omits the separate field, because the reporter appends `suggestion` *after* the rationale — so a rationale ending in `</details>` would otherwise leave the fix stranded below the collapsed block [observed: `templates/coordinator.md:28-36`; `src/core/render.ts:255-261`].

+A trailing slash is shape, but not enough on its own. Prompts for a repo of many
+packages say `ios/`, `src/` or `android/src/` meaning *each package's* directory of that
+name, and no single ref can pin that: `ios/` does not exist at the root, and
+`glob:**/ios/**` matches the whole tree, so it would verify nothing. So a trailing-slash

+one of them a package-relative name whose suggested fix could never resolve [observed].
+The tradeoff is the extensionless one again: a misspelled `iso/` or a deleted `oldpkg/`
+still fails, but a stale `foo/bar/` whose name survives somewhere else
+in the tree goes quiet.

+Every suggested fix must itself resolve, or following the message trades one failure
+for another. A partial path (`start/doctor/apple/XcodePrerequisite.ts`) is taught the
+one repo file it is a suffix of, or `glob:**/<token>` when several are, and a suffix glob
+covers the partial path it was written for: coverage reads each `**/` as zero or more
+directories, as routing does ([LLP 0004][dialect]), while resolution keeps the shared
+dialect unchanged, so `./ref-check` needs no change. A wildcard directory
+(`packages/*/apple/`) is taught `glob:packages/*/apple/**`, since a glob matches files
+only, and a leading `./` is dropped, since repo paths never carry one. A citation that matches nothing at
+all gets no suggestion: the message says it does not resolve and may be stale, which is
+usually the real finding.
