+### Added
+
+- **Path-scoped `ignore.rules` (#680).** An entry can be an object, `- rule: bug-println` with `files: ["crates/cli/**"]` and an optional `reason`, to silence a rule in some directories only while it keeps firing elsewhere; plain strings still silence a rule everywhere. An empty `files` list is a config error. Works in `review`, `scan` and the MCP tools. See `docs/configuration.md`.
+- **Cora Review can use Anthropic workload identity federation (no stored API key).** The review job exchanges its GitHub OIDC token for a short-lived Anthropic access token (when `ANTHROPIC_FEDERATION_RULE_ID`, `ANTHROPIC_ORGANIZATION_ID`, `ANTHROPIC_SERVICE_ACCOUNT_ID` and `ANTHROPIC_WORKSPACE_ID` are set) and sends it only to `api.anthropic.com`; otherwise it falls back to `CORA_API_KEY`, `CORA_BASE_URL` and `CORA_MODEL`. A smoke test workflow verifies the exchange and a Bearer call to `/v1/chat/completions`. See `docs/examples.md`.
+- **`cora.scan_prepare` speaks the CLI's selection language (#686).** The MCP tool accepts `include`/`exclude` globs, `extensions`, `incremental` and `changed_since` (git rev), orders batches source-first (code before docs/data/lockfiles, shallower first; `order: "path"` keeps walk order), and returns planning data — `total_chars`, `estimated_tokens` and per-batch file counts — so an agent can scope a scan before spending tokens. `cora.scan_finalize` takes the same inputs; a fingerprint mismatch refuses the call. See `docs/usage.md`.
+- **Agents validate before they commit (#674).** A review of the staged diff, by an agent (`cora.review_finalize`) or by `cora review --staged`, now leaves a marker bound to that exact change set. `cora hook verify` reports it (exit 0 validated, 10 validated but blocking, 11 not validated) and `cora hook claude-guard` is a Claude Code `PreToolUse` hook that denies a `git commit` that is unreviewed, blocking, uses `--no-verify`, or is not a plain commit of the staged change. The pre-commit hook (now v2, upgraded in place by `cora hook install`) accepts a validated diff and otherwise falls back to `cora review --staged --ci --severity major`; a tooling error is reported as "not a pass". The `/cora-review` skill tells agents to review before every commit. See `docs/usage.md`.

+- **`bug-println` treats a binary crate as program code (#682).** Every module of a package that has `src/main.rs` and no `src/lib.rs` is exempt (stdout is its interface), not only `main.rs`, `src/bin/`, `examples/` and `benches/`. A library package, or one with both `main.rs` and `lib.rs`, keeps the rule, so a core crate can still guard against writing to stdout. Together with the `eprintln!` and `.expect("...")` changes this closes #682.
+- **`--help` no longer prints `CORA_BASE_URL`, `CORA_MODEL` or `CORA_PROVIDER` values (#687).** A base URL can carry credentials (`user:pass@host`, `?key=...`) and the other two name internal deployments; like the API key, their `[env: ...]` values are hidden (clap `hide_env_values`).
+- **`cora scan` is quieter and says what it found (#683).** The `qual-clone` hint (`.clone()` in Rust, 306 info findings on one workspace) is now opt-in via `rules_engine.clone_hints: true`. New `cora scan --min-severity <info|minor|major|critical>` hides lower findings in every output format and in the count (blocking is still decided by `hook.min_severity`), and the summary counts by severity: `found 457 issues (1 critical, 150 minor, 306 info)`.
+- **Models that reject `temperature` work (#701).** cora always sent `temperature` (default `0.0`); newer models such as `claude-opus-5-5` answer HTTP 400 "`temperature` is deprecated for this model" and the review ended as "could not complete". A 400 that names `temperature` is now retried once without it and remembered for the model for the rest of the process; every other 400 is returned unchanged, and providers that accept it keep the configured value.
+- **`crypto/hardcoded-secret` no longer flags `CancelToken::default()` and `review_prepare` matches `review_finalize` (#697).** A path such as `Token::default()` was read as `token: <value>`; the value after a single `:` can no longer start with another `:`. `cora.review_prepare` now applies `ignore.rules`, inline `cora-ignore` markers and the context filter to `deterministic_findings`, so the agent no longer sees (and fixes) a finding that `review_finalize` would drop.
+- **`cora.scan_finalize` reports how much of the project the verdict covers (#685).** New optional input `batches_judged`; the result has `coverage` (`complete`, `partial`, or `unverified` when not declared), `total_batches`, `batches_judged`, `files_judged` and `files_total`. A partial run says `Judged 1/11 batches (3/23 files)` and `should_block` is null instead of false. The `/cora-review` skill now passes `batches_judged`.
+- **Three built-in rules stop flagging idioms (#681, part of #682).** `bug-todo` fires only on a deliberate marker: upper-case `TODO`, `FIXME`, `HACK` or `XXX` inside a comment (not `pub mod todo;`, `todo_state` or the word "todo" in prose). `bug-println` no longer matches `eprintln!` / `eprint!` (stderr diagnostics). `bug-expect` flags only `.expect("")`; a non-empty message states an invariant and is the recommended alternative to `unwrap()`. Treating every module of a binary crate as program code is still open in #682.
+- **Custom rules are validated and the docs match the schema (#684, #678).** `cora config validate` and config load now reject an invalid regex, an empty or duplicate id, an id that shadows a built-in rule, an empty message and an unknown `languages` value, naming the rule. `languages` accepts language names (`"rust"`) as well as extensions (`"rs"`); `languages` and `exclude` are optional. `cora config validate --dry-run [--path DIR]` runs each custom rule and prints how many lines it matched. `docs/configuration.md` now shows the real schema (`rules_engine.custom`); the 0.19.0 entry no longer says `custom_rules`.
+- **`cora-ignore` no longer fails silently (#679).** A marker on a line with findings that names none of them (a typo, an unknown rule, or explanation text that became part of the rule name) now prints a warning on stderr naming the marker and the rule ids on that line. ` -- ` ends the rule list, so `cora-ignore: sec-hardcoded-secret -- env var name` suppresses the finding and keeps the reason in the source.
+- The `Cora Review` workflow now fails with an error naming each empty secret (`CORA_API_KEY`, `CORA_BASE_URL`, `CORA_MODEL`) instead of running without them.
+- The `Cora Review` job no longer gets cancelled on larger pull requests: its time limit is 30 minutes (the review action allows up to three LLM attempts of 10 minutes each).

 - If an LLM finding and a scanner finding on the same line describe the same problem (they share a topic word, e.g. both are about a hardcoded password/secret), only the LLM finding is reported, and a marker (or `ignore.rules` entry) naming the scanner rule's id or title still suppresses it. If the LLM finding is about something else (say SQL injection next to a hardcoded secret), both are reported and a marker only suppresses the one it names.
 - Scope: the same line; plus the next line when the marker line contains only a comment.
 - A bare `cora-ignore` (no `:` or empty rule list) suppresses nothing, so every suppression names its rule.
+- The rule list runs to the end of the line (or the comment terminator). Put an explanation after ` -- `: `// cora-ignore: sec-hardcoded-secret -- env var name, not a value`. Text without the separator becomes part of the rule name.
+- A marker on a line that has findings but names none of them (a typo, an unknown rule, trailing text) prints `warning: cora-ignore at FILE:LINE matched no finding ...` on stderr, listing the rule ids that are on that line.
 - Applies to both deterministic scanner and LLM findings, in both `cora review` and `cora scan`. Other rules on the same line and the rest of the project stay visible. Works alongside `ignore.rules` and `ignore.files`.
 - `cora review` reads markers from the diff (added and context lines); a marker outside the diff's context window is not seen. `cora scan` reads markers from the full file contents.
 - `cora scan` also runs the deterministic secrets and security scanners on every scanned file and applies `ignore.rules`, so those findings are reported even when the LLM call fails.
 
+## Path-scoped ignore rules
+
+`ignore.rules` entries can be plain strings (the rule is silenced everywhere) or objects that silence a rule only under some paths:
+
+```yaml
+ignore:
+  rules:
+    - "Hardcoded password or secret"          # whole project
+    - rule: bug-println
+      files: ["crates/cli/**", "evals/**"]    # only these paths
+    - rule: bug-expect
+      files: ["**/subprocess.rs"]
+      reason: "expects state a local invariant"   # optional, for reviewers
+```
+
+`rule` is matched like a plain entry (rule id or title fragment). `files` uses the same globs as `ignore.files` and must not be empty (an empty list is a config error). It applies to `review`, `scan` and the MCP tools, before the `max_findings` cap. `reason` is documentation for the people reading the config.
+
 ## Ignore Files
 
 Exclude files or directories from **all** cora operations — review, scan, and indexing. This is the broadest exclusion mechanism.

+### Anthropic with workload identity federation (no stored API key)
+
+Instead of a long-lived `CORA_API_KEY`, the job can exchange its GitHub OIDC token for a short-lived Anthropic access token. Create a federation rule in the Anthropic Console (issuer `https://token.actions.githubusercontent.com`, audience `https://api.anthropic.com`, a **subject prefix** that matches your repository), then provide `ANTHROPIC_FEDERATION_RULE_ID`, `ANTHROPIC_ORGANIZATION_ID`, `ANTHROPIC_SERVICE_ACCOUNT_ID` and `ANTHROPIC_WORKSPACE_ID` (and optionally `ANTHROPIC_MODEL`) as organization or repository secrets or variables.
+
+GitHub now issues subjects with numeric ids, for example `repo:my-org@289767358/my-repo@1254014703:pull_request`; a prefix written as `repo:my-org/my-repo:` never matches it. The Anthropic Console authentication log shows the reason for a denial (`match_subject_prefix`).
+
+The job needs `permissions: id-token: write`. The exchanged token is sent only to `https://api.anthropic.com/v1` (never to `CORA_BASE_URL`), and when federation is unavailable the job falls back to the `CORA_*` secrets. This repository's `.github/workflows/cora-review.yml` and `anthropic-wif-smoke.yml` are a working reference.

+## Gate every commit (agent first, hook as fallback)
+
+Three layers, strongest first:
+
+1. **Agent judge.** The agent reviews `git diff --cached` with the `/cora-review` skill and calls `cora.review_finalize` with the exact staged diff. Cora records the verdict for that change set.
+2. **Pre-commit hook** (`cora hook install`). If the staged diff is already validated it passes; otherwise it runs `cora review --staged --ci --severity major` (an LLM when configured, deterministic checks otherwise). Exit 2 denies the commit; any other exit is a tooling error, reported as "not a pass".
+3. **CI.** Run `cora review` on pull requests to `develop`, and fail the job when its secrets are missing.
+
+`cora hook verify` prints the state of the staged diff: exit 0 validated, 10 validated but blocking, 11 not validated. Any edit to the staged change invalidates the verdict (24 h expiry).
+
+To stop Claude Code from committing unreviewed changes or using `--no-verify`, add this to `.claude/settings.json`:
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      { "matcher": "Bash", "hooks": [{ "type": "command", "command": "cora hook claude-guard" }] }
+    ]
+  }
+}
+```
+
+The guard is a safety net for honest agents, not a sandbox; the hook and CI remain the enforcement.
+

+//! Commit gate (#674): a verifiable record that a staged diff was reviewed.
+//!
+//! Three tiers share one record:
+//!
+//! 1. an agent judges the staged diff (`cora.review_finalize`) or a person runs
+//!    `cora review --staged`; either records a [`Marker`] for that exact change
+//!    set in `<git-dir>/cora/validations/`;
+//! 2. the pre-commit hook asks [`check`] first and only falls back to a full
+//!    review when there is no marker;
+//! 3. an agent's `git commit` can be denied by `cora hook claude-guard`, which
+//!    asks the same question.
+//!
+//! A marker is keyed by a fingerprint of the *change set* (file paths plus the
+//! added and removed lines), not of the diff text, so it survives different
+//! context sizes, `index` line abbreviations, and prefix settings. It carries no
+//! source code: only the fingerprint, who judged, and the verdict.
