@@ -28,21 +30,156 @@ this repo's fix history, each with a check to run against the diff. The comment
 fails or times out, the runner (not the model) adds a line to the comment saying which area went
 unreviewed.
 
+Each reviewer runs as several cold passes: independent opencode sessions with no shared context,
+so one pass's misses can be another's catches (backtesting on DeepSeek showed one pass misses
+findings two catch). The variable `AI_REVIEW_COLD_PASSES` sets the count (default `2`, clamped to
+1–3; `src/passes.mjs`). The coordinator gets every pass's report labelled `<Reviewer>, pass N/M`
+and keeps a finding raised by any pass, merging duplicates; the fallback comment unions the passes
+and folds findings at the same file and nearby line when one title's words contain the other's (two P0/P1 blockers fold only on the same title). An area counts as
+reviewed when any of its passes finished, and the comment notes a lost pass. Each pass is billed,
+so the review costs about M times one pass; reviewer spans carry `review.pass`.
+
 The coordinator also lists the findings it kept in a hidden JSON block, which the runner strips
-from the comment. Kept blockers and warnings whose `file:line` is an added or context line of the
+from the comment. Kept P0, P1 and P2 findings whose `file:line` is an added or context line of the
 diff are posted as one `COMMENT` review with inline threads (at most 10, never approve or request
 changes). Each thread carries a hidden fingerprint of file and title, so a re-run skips findings
 already posted by `REVIEW_BOT_LOGIN`. A failed inline post only logs a warning. The threads are
 off by default; set the variable `AI_REVIEW_INLINE` to `true` to turn them on.
 
-Each PR gets at most `AI_REVIEW_MAX_PASSES` automatic reviews (default 2). The count is a hidden
-`o2-review-pass` tag in the review comment, written before the reviewers start, so a run cancelled
-by a newer push still counts; later pushes skip before any model call. A run in which every
-reviewer failed gives its pass back. The paired pointer and the "key not set" notice keep the tag.
-If the bot's comments cannot be read (no reviewer app token, or the list call fails) the run fails
-instead of reviewing, since the count cannot be checked. To review again, dispatch the workflow with
-`ignore_pass_limit` (forwarded to a paired o2-enterprise review), or delete the review comment to
-reset the count.
+Findings are graded `p0` to `p3`. P0 and P1 are blockers and give the decision `blocked`; P2 and P3
+do not block, and only those give `approved_with_comments`; no findings gives `approved`. A review
+keeps at most 3 P2 and 2 P3 findings: the coordinator is told to drop the rest, and the runner
+enforces the cap itself only in the fallback comment it renders when the coordinator fails. Legacy
+severity words from a reviewer are mapped in `src/severity.mjs`. The review stays advisory: the check does not go red on a blocker.
+
+Every new commit gets one review, and the last reviewed commit is not reviewed again. Only the
+latest review is recorded, so a force-push back to an older reviewed head is reviewed again. A
+finished review records what it covered in a hidden `o2-review-sha` tag (the head SHA, plus the paired head in a
+paired review, so a new commit on either side is new) and shows it in a visible `Reviewed commit`
+line with the review number. A run whose head matches the tag skips before any model call, which
+covers a queued run, a re-label and a plain dispatch, including the paired dispatch from
+openobserve. The tag is only written when it is true: the diff the reviewers read is rebuilt locally
+from `MERGE_BASE_SHA` and `HEAD_SHA` (both sides of a paired review), because the API serves the
+branch as it is now. If that cannot be done, or no reviewer finished (each one failed or returned
+nothing parseable), the run writes no tag and names no commit, so that commit can be reviewed again.
+A run where no reviewer finished also reports `Not reviewed` and fails the check.
+
+There is no cap on reviews per PR unless the variable `AI_REVIEW_MAX_PASSES` is a positive integer;
+unset, empty, `0` or an invalid value means no cap. Reviews are counted either way, in a hidden
+`o2-review-pass` tag written before the reviewers start, so a run stopped by removing the label or
+by a draft conversion still counts. A run in which no reviewer finished gives its pass back. The
+paired pointer and the "key not set" notice keep the tag. When a cap is set and reached, later
+pushes skip before any model call and the limit note on the comment names the commit that was
+reviewed and the one that was not. If the bot's comments cannot be read (no reviewer app token, or
+the list call fails) the run fails instead of reviewing, since neither the reviewed commit nor the
+count can be checked.
+
+A push does not cancel a review in progress: the paid run finishes and only the newest push waits
+in the concurrency queue. To review a commit again, dispatch the workflow with `ignore_pass_limit`
+(it bypasses both the dedupe and the cap, and is forwarded to a paired o2-enterprise review) or with
+`force_full` (it bypasses the dedupe only), or delete the review comment to reset the count.
+
+The comment marker is matched as a pattern, so a retired provider leg's comment is adopted and
+rewritten in place, including older comments whose marker was redacted to
+`<!-- ai-code-review-[redacted] -->`. The marker is added after redaction, so it survives verbatim
+even when it names the provider.
+
+## Merge confidence
+
+The comment carries one line right after the decision callout, for example
+`**Merge confidence: 🟢 High** — no blockers; all reviewers finished; tests changed`. The runner
+computes it from facts in `src/confidence.mjs`; the model cannot write it, and any such line in its
+output is stripped. It is advisory evidence, not a guarantee: reviewers sample the code.
+
+| Level | When (the lowest that applies wins, every cause is listed) |
+|-------|---------------------------------------------------------------|
+| 🔴 Low | Any P0 or P1; the kept findings could not be counted; the Security or Correctness reviewer did not finish; no reviewer finished or ran |
+| 🟡 Medium | Any other reviewer did not finish; the coordinator failed, so findings are un-judged; any P2; production code changed with no test changed |
+| 🟢 High | Otherwise. P3 findings alone do not lower it |
+
+Production means `src/`, `web/src/` and the enterprise `o2_*/src/` trees, outside test paths. Tests
+mean `tests/`, `test/`, `__tests__/`, `*.spec.*`, `*.test.*`, and Rust files that add `#[test]`,
+`#[tokio::test]` or `#[cfg(test)]`. Both are read from the unfiltered diff, so a production file
+the noise filter hides from reviewers still counts. A paired review counts both repos. When a cap is set and a push
+is skipped at it, the line turns to 🔴 Low and names the unreviewed commit, until a full review
+replaces it.
+While a run reviews a new commit, the line reads `**Merge confidence: 🟡 Reviewing**` and names that
+commit, so an earlier level never stands for it; the final review replaces the line, and a cancelled
+run leaves it in place. The level it replaced is kept in a hidden `o2-review-held` tag: if the head
+later returns to the reviewed commit, the skip restores that level, at no pass and with no model
+call, while the gate's line stays off because its approval was dismissed. The level is the trace attribute `review.merge_confidence` and `merge_confidence` in the findings
+artifact.
+
+## Auto-approve for small PRs
+
+Small, low-risk PRs can skip the human reviewer. The PR title, body, diff and file names are
+untrusted input to a model that can be prompt-injected, so the model's verdict alone can never
+approve: `src/auto-approve.mjs` checks every condition in code, and any failure, or any fact it could
+not read, means a human reviews. The bot never merges; it has no Contents write.
+
+All of these are required:
+
+1. The reviewers ran under the read-only `default` config. Under `ci-full` they have a shell while
+   the parent process holds the app token, so `approve` is ineligible with "reviewers can run
+   commands". `shadow` records that reason too, plus `eligible_ignoring_config`, so the data stays
+   useful while the workflow sets `ci-full`.
+2. The raw diff has at most 100 changed lines and 5 files, with no binary file, mode change, symlink,
+   submodule, file path that cannot be read, or rename/copy whose header shows no file mode (an
+   unchanged rename does not say whether it moved a symlink or submodule). The diff is rebuilt locally from `MERGE_BASE_SHA` and
+   `HEAD_SHA` in `./pr` before any reviewer starts, and the reviewers and every size condition use
+   that pinned diff. If it cannot be built the review carries on with the API diff and the run is
+   ineligible.
+3. Every raw file was reviewed: no filtered file, no truncation, and the diff agrees with the PR's
+   `changed_files`, `additions` and `deletions`.
+4. No path, old or new, matches `SENSITIVE_PATHS`.
+5. Merge confidence is High, no reviewer reported a finding and none was kept, the findings were
+   counted (one inline block, every entry with a title and a known severity), the coordinator did not fall back, and the decision callout of the sanitized text, the one that gets posted, is an approval.
+6. The Security and Correctness reviewers ran and finished, as did every other selected reviewer,
+   and each one that ran saw the whole filtered diff. Finished means the output parsed into findings
+   or held a complete `<no-issues>` element, inside a `<findings>` report that is not in a code span or an HTML comment, with no `<finding>` or `<findings>` left open and no
+   `<finding>` block left unread; empty, free-form or cut-off text does not count, even after an earlier
+   finding parsed, and also keeps confidence below High. A PR within the size limit is forced to the `full` tier with `fileFocus` bypassed whenever
+   the mode is not `off`; agents that require focus may still opt out when no file is in their domain.
+7. It is not a paired review, and the workflow proved that: only its "no open PR on this branch"
+   path sets `REVIEW_PAIR_CLEAR`. A failed lookup, a missing token, a failed dispatch or
+   `ignore_paired` leaves it unset, which is ineligible.
+8. The author is not a bot and is an `OWNER`, `MEMBER` or `COLLABORATOR`.
+9. The title, body, file paths and added lines hit no injection tripwire (phrases aimed at the
+   reviewers, review markers, invisible Unicode), matched after NFKC, lowercasing and whitespace
+   folding, with a letters-only pass for spaced-out phrases. Added lines and file paths must be
+   printable ASCII or tab; the title and body may carry emoji but no Cyrillic or Greek letters. A hit
+   disqualifies without proving intent, and the reason never echoes the text. The title and body
+   checked are the exact ones given to the reviewers, and the PR re-read at the end must still match
+   them: an edit after the review started is ineligible, even one that removes a hit.
+10. There is no `no-auto-approve` label and no outstanding `CHANGES_REQUESTED` review.
+11. Re-read right before deciding, the PR head still equals the reviewed commit, the PR is open and
+    not a draft, and its base branch is `main`.
+
+The mode comes from `AI_REVIEW_AUTO_APPROVE`, passed as `REVIEW_AUTO_APPROVE`:
+
+| Mode | Effect |
+|------|--------|
+| `off` | The engine default, and what any unknown value means. No reads, no writes. |
+| `shadow` | The workflow default. Decides and records `auto_approve` in the findings artifact and `review.auto_approve.*` on the trace. Nothing shows on the PR and nothing is written. |
+| `approve` | Submits an `APPROVE` review pinned to the head commit, and adds `**Auto-approved**` or `**Needs human review** — <reasons>` under the confidence line. Never requests changes. |
+
+In `approve` mode every run for a new commit first dismisses the bot's earlier approvals, before any
+reviewer starts, so an approval never survives a later push. A failed dismissal is a warning and
+makes the run ineligible. A failed approval is a warning and never fails the job.
+
+### Before turning on approve
+
+0. Restrict the `ai-review` environment to `main` in both repos. It has no branch policy today, so a
+   workflow added on any branch can read its secrets.
+1. Run the reviewers on the read-only config: set `REVIEW_OPENCODE_CONFIG` to `default` in the
+   workflow. Until then every run is ineligible, whatever the variable says.
+2. Turn on "dismiss stale approvals on push" in `main`'s ruleset. The engine dismisses its own
+   approvals only when it runs, and no engine run happens on a paired deferral, a disabled workflow
+   or a setup failure.
+3. Confirm an approval from the app satisfies the required review on `main`; that depends on the
+   ruleset. CI must still pass either way.
+4. Leave `shadow` on and grade the artifact's decisions against what humans did. Use
+   `eligible_ignoring_config` while the workflow is still on `ci-full`.

 ## Severity Definitions
 
-- **critical**: Will cause an outage, data loss, or is exploitable — or, for test changes, a coverage-integrity failure (a test that passes while asserting nothing real: a missing/vacuous/soft/un-awaited assertion, or a selector that matches no component). Must block merge.
-- **warning**: Measurable regression, concrete risk, or pattern that leads to bugs. Should be addressed.
-- **suggestion**: An improvement worth considering. Does not block merge.
+- **p0** (blocker): An outage, data loss or corruption, an exploitable security hole, or a default path broken for all users.
+- **p1** (blocker): A real bug that normal use or normal config reaches: wrong results, a crash, a failed request, a regression. Also, for test changes, a coverage-integrity failure (a test that passes while asserting nothing real: a missing/vacuous/soft/un-awaited assertion, or a selector that matches no component).
+- **p2** (not blocking): A real bug that needs unusual input, rare timing or non-default config; a measurable regression off the hot path; a broken project rule with no runtime effect.
+- **p3** (not blocking): A likely bug with one unverified step.
 
-A warning needs a concrete failure scenario or a named project rule it breaks (the QA and frontend house rules count); drop a warning that has neither. Keep at most 3 suggestions, the most valuable ones, and drop the rest.
+Grade every finding by reachability: who hits the failure, and what they must do to hit it. Never soften a severity to be polite. If a normal user reaches it without unusual setup it is `p1`, not `p2`.

 1. **Only report problems this PR introduces or leaves incomplete.** Unchanged code is in scope when the change relies on it or leaves it wrong: a caller or consumer that still uses the old semantics, a sibling code path that should enforce the same rule, a match arm or key the new code depends on that never fires, the other half of a parity pair. Name the changed line that creates the dependency. Unrelated pre-existing bugs stay out.

If one step of the trace is unverified, say which and use suggestion severity. A claim about how a library, framework, browser or test runtime behaves ("jsdom does not keep X", "this selector matches nothing", "the crate panics on Y") needs evidence you read: its source, its docs, or a test in this repo that shows it. Without that, it is a suggestion at most, never a blocker.

 3. **No style nitpicks.** Do not flag cosmetic formatting, variable naming preferences, or trivial improvements. Only flag style if it violates established project conventions (e.g., clippy lints in Rust, ESLint rules in TypeScript).
 4. **No flattery.** Do not include "Great job", "Thanks for", "Nice work", or any non-actionable commentary.

Suggestion is for a likely bug with one unverified step (rule 2).
+5. **Severity must be justified, and is graded by who can reach the failure.** Use one of four levels:
+   - `p0` (blocker): an outage, data loss or corruption, an exploitable security hole, or a default path broken for all users.

-- **On-call ack-token tests skip** — they read the paging mail to get the acknowledgement token, which exists only in the delivered message. Start Mailpit (`MAILPIT_BASE_URL`, default `http://127.0.0.1:8025`) and point the server at it with `ZO_SMTP_ENABLED=true ZO_SMTP_HOST=127.0.0.1 ZO_SMTP_PORT=1025`.

+- **On-call ack-token tests skip locally** — they read the paging mail to get the acknowledgement token, which exists only in the delivered message. Start Mailpit with `mailpit --smtp 127.0.0.1:1025 --listen 127.0.0.1:8025 --smtp-allowed-recipients '(?i)@test\.invalid$'` (the filter makes mail to the reachability tests' other domain a real refusal), point the server at it with `ZO_SMTP_ENABLED=true ZO_SMTP_HOST=127.0.0.1 ZO_SMTP_PORT=1025 ZO_SMTP_FROM_EMAIL=oncall@ci.openobserve.test`, and set `MAILPIT_BASE_URL` if it is not `http://127.0.0.1:8025`. With no mailbox they skip locally and fail when `CI` is set. The enterprise `ent_oncall` shard starts Mailpit v1.21.8 on 1025/8025 with that recipient filter and starts the server with the same SMTP settings.
 - **`test_workflow.py` fails with SMTP error** — `ZO_SMTP_ENABLED=true` not set. CI does this; locally you'd need to wire an SMTP env.
 - **Test_organisations.py warning about `yield`** — `test_create_organization` uses pre-pytest-4 yield-style and is silently ignored. Scheduled for rewrite in Phase 4.

-   * TS-03.05 — PARKED. A real product gap, not a test that asks too much.
-   *
-   * `delete_team` (o2-enterprise .../oncall/service.rs:183) refuses ONLY when the
-   * team is the org's nominated default. Past that it deletes ownership rules,
-   * overrides, schedules and policies — and never queries `oncall_responses` at
-   * all. Its own doc comment states the intent: "Response records are kept: they
-   * are history, and history has to survive a reorg."
-   *
-   * That reasoning holds for a RESOLVED record. It does not hold for an OPEN one:
-   * the delete succeeds (200), the page stays `triggered` against a `team_id`
-   * that no longer resolves, and nothing escalates it any further — the ladder,
-   * the schedule and the policy it would have climbed were all just deleted. The
-   * record is not history; it is a live page nobody will ever be woken for, and
-   * no timeline entry says why.
-   *
-   * The asymmetry is the argument that this is an oversight rather than a
-   * decision: taking ONE MEMBER off a team already does the check. The same file
-   * carries `open_records_acknowledged_by` (service.rs:1038), which calls
-   * `oncall_responses::list_open` for the team and reports the open records that
-   * person can no longer close. Deleting the entire team — which strands every
-   * open record, not one person's — skips it.
-   *
-   * The test accepts EITHER honest answer — refuse and name what is still open,
-   * or allow and close the record with a timeline entry. The product does
-   * neither, verified 16 Sep on :5090. The body is left intact so it goes green
-   * the day one of the two is implemented.
