pr-management-stats: require full engagement schema + add reference impl
(#257)
* pr-management-stats: require full engagement schema + add reference impl
Fixes three correctness issues in pr-management-stats that cause severe
under-counting of engagement and over-counting of untriaged PRs:
1. `fetch.md` previously said "no statusCheckRollup / mergeable /
reviewThreads" — claiming none were needed for stats. This is wrong
for `reviewThreads`, `latestReviews`, and `timelineItems`: the
`is_engaged` predicate in classify.md explicitly counts maintainer
line-level review comments, submitted reviews, and label/draft
timeline events as engagement. Omitting those fields means a
maintainer who only left a line-level review comment is treated as
"no engagement" and the PR is misclassified as untriaged. On a
~530-PR queue this inflates the untriaged count ~10× (observed:
225 → 24, then 24 → 2 with full schema + reviewThreads added).
2. `SKILL.md` had no explicit no-skip rule for the 11 dashboard panels.
Agents under context pressure were observed simplifying away the
line charts, CODEOWNERS table, and triager-activity table. New
Golden rule 8 requires all sections to render; missing-data
stubs are allowed but silent omission is not.
3. New Golden rule 9 documents the FULL engagement schema explicitly
so agents don't trim the query "to save complexity points".
Also adds:
- `tools/pr-management-stats/reference.py` — canonical reference
implementation of the fetch + classify contract. Encodes the full
engagement schema and serves as the single source of truth agents
can read from.
- `tools/pr-management-stats/README.md` — describes how the agent
invokes the reference + the anti-skip contract.
- Updated GraphQL template in fetch.md to include the engagement
fields, with batch size dropped from 50 to 30 to absorb the
~11-point complexity increase per page.
* chore(ci): fix dependabot cooldown schema and bump pinned actions
The github-actions and pre-commit ecosystem blocks in
.github/dependabot.yml carried `semver-{major,minor,patch}-days`
cooldown keys, which those ecosystems do not accept. Dependabot
rejected both blocks outright with:
The property '#/updates/0/cooldown/semver-major-days' is not
supported for the package ecosystem 'github-actions'.
The property '#/updates/1/cooldown/semver-major-days' is not
supported for the package ecosystem 'pre-commit'.
...
which is why neither ecosystem produced a single PR in the four
weeks since adoption on 2026-04-29 (the uv blocks were unaffected
and ran normally — see #130, #233). Strip the unsupported keys and
keep `default-days: 7` for the 7-day settle window.
Apply the bumps that would have landed already had dependabot been
running, all past the 7-day cooldown:
actions/cache v4.2.2 -> v5.0.5
github/codeql-action v4.35.2 -> v4.35.5
zizmorcore/zizmor-action v0.5.2 -> v0.5.6
astral-sh/setup-uv v7.3.0 -> v8.1.0
actions/cache@v5 needs runner >= 2.327.1 (Node 24), which the
GitHub-hosted runners we target already satisfy. setup-uv@v8 is a
major bump; CI on this commit is the smoke test.
ASF allowlist: setup-uv@08807647 and zizmor-action@5f14fd08 are
already on approved_patterns.yml. actions/cache and
github/codeql-action are exempt — `actions` and `github` are in
TRUSTED_OWNERS in apache/infrastructure-actions/allowlist-check/
check_asf_allowlist.py.

* fix(pr-management-stats): use placeholders in fetch.md + README example
`check-placeholders` pre-commit hook (and skill-validator pytest)
rejected hardcoded `apache/airflow` references in:
.claude/skills/pr-management-stats/fetch.md:414
tools/pr-management-stats/README.md:39
Replace with `<upstream>` (the skill's existing placeholder for the
project repo, used on fetch.md lines 171, 178, 185, 193, 203, 223,
238, 348). Also swap `potiuk` for `<maintainer-handle>` in the
README invocation so the example matches the placeholder convention
end-to-end. doctoc TOC added by pre-commit on first README edit.
Generated-by: Claude Code (Opus 4.7)
* fix(pr-management-stats): typos in reference.py flagged by `typos` hook
prek's `typos` hook caught:
- `invokable` -> `invocable` (docstring, line 23)
- `thr` -> `thread` (loop variable in the reviewThreads walk,
lines 257-258)
Pure rename + spelling fix; no behaviour change.

-## Why no `statusCheckRollup` / `mergeable` / `reviewThreads`
-
-`pr-management-triage` needs all three for classification;
`pr-management-stats` does not. Dropping them keeps the query complexity well
below GitHub's per-page ceiling, which is how we can safely run `batchSize=50`
here versus `20` in `pr-management-triage`. If a future stats column ever needs
one of those fields, raise only that query's complexity — don't pull them into
the default shape "just in case".
+## Why no `statusCheckRollup` / `mergeable` — and why `reviewThreads` IS
required
+
+`statusCheckRollup` and `mergeable` are not needed for stats — those drive
+per-PR classification in `pr-management-triage` but aggregate counts don't use
+them. Dropping them keeps the query lighter, which is how we can run a larger
+`batchSize` here (30–50) than in `pr-management-triage` (20).
+
+`reviewThreads`, `latestReviews`, and `timelineItems` (for
+`LABELED_EVENT`/`READY_FOR_REVIEW_EVENT`/`CONVERT_TO_DRAFT_EVENT`), **on the
+other hand, ARE required** for stats — the `is_engaged` predicate in
+[`classify.md`](classify.md) counts maintainer engagement across:
+
+- issue comments (`comments`) — already included
+- submitted reviews (`latestReviews`) — required
+- line-level review comments (`reviewThreads`) — required
+- label adds + draft conversions by maintainers (`timelineItems`) — required
+
+A maintainer who left only a line-level review comment (no issue comment, no
+submitted review) would otherwise look like "no engagement" and the PR would
+be misclassified as untriaged. On a large queue the under-count is material —
+on `<upstream>` (~530 open PRs at the time of writing) it inflates the
untriaged count by ~10×.
+
+(An earlier iteration of this doc claimed `reviewThreads` was not needed for
+stats; that was a documentation bug. The current schema in the OPEN_PRS_QUERY
+template above includes all four engagement signals. The same fix is encoded
+in the reference implementation at
+[`tools/pr-management-stats/reference.py`](../../../tools/pr-management-stats/reference.py).)
+
+If a future stats column ever needs `statusCheckRollup` or `mergeable`, raise
+only that query's complexity — don't pull them into the default shape "just
+in case".

+# pr-management-stats reference implementation
+
+Deterministic reference implementation of the data-fetch +
+classification contract that backs the
+[`pr-management-stats`](../../.claude/skills/pr-management-stats/SKILL.md)
skill.
+
+The skill's agent-emitted render is the **default** — this script
+exists for two reasons:
+
+1. **Anti-skip insurance.** Agents under context pressure can be
+ tempted to omit panels from the dashboard (line charts, CODEOWNERS
+ table, triager-activity table). The skill specifies all 11 panels;
+ agents must render them all. This script encodes the canonical
+ data-fetch shape so the agent has a single source of truth to read
+ the fields from — there is no "the skill says X, the agent guessed
+ Y" drift.
+
+2. **CI-renderable artefact.** Adopters who want a daily dashboard
+ rendered by CI (rather than an interactive agent session) can run
+ this script on a schedule, extend it with the full render per
+ [`render.md`](../../.claude/skills/pr-management-stats/render.md),
+ and publish the HTML as a build artefact or gist.
+
+## Layout

+```
+
+The script:
+
+1. Fetches all open PRs with the **full engagement schema**
+ (`comments`, `latestReviews`, `reviewThreads`, `timelineItems`
+ with `LABELED_EVENT`/`READY_FOR_REVIEW_EVENT`/`CONVERT_TO_DRAFT_EVENT`).
+2. Fetches closed/merged PRs since the cutoff.
+3. Fetches `.github/CODEOWNERS` + changed-file paths for each
+ currently-ready PR.
+4. Classifies each PR per
+ [`classify.md`](../../.claude/skills/pr-management-stats/classify.md) —
+ `is_engaged` requires ANY maintainer touch (issue comment, review,
+ review-thread comment, label add, draft conversion).
+5. Writes a JSON sidecar with all the counts that feed the dashboard.
+
+## Contract for the agent
+
+When the agent invokes the skill, it MUST:
+
+- Use the GraphQL templates from
[`fetch.md`](../../.claude/skills/pr-management-stats/fetch.md) verbatim. **In
particular, the open-PRs query MUST include `reviewThreads` and `latestReviews`
and `timelineItems`** — without those, the `is_engaged` predicate is
undercounted and untriaged numbers blow up artificially. (Earlier iterations of
`fetch.md` claimed those fields were not needed for stats; that was a
documentation bug and has been corrected.)
+- Implement ALL 11 sections per
[`render.md`](../../.claude/skills/pr-management-stats/render.md). Skipping
panels (e.g. dropping the line charts, CODEOWNERS table, triager-activity
table) is **not** an acceptable simplification.
+- If panel data is unavailable, the panel renders a stub with a one-line
explanation of WHY the data is missing — never omit a section silently.
+
+## Parity implementations
+
+This script is a fetch + classify reference. The full render lives
+in the agent-emitted version per `render.md`. Adopters who want a
+deterministic CI-runnable equivalent should extend this script with
+the aggregation + HTML emission directly; we welcome PRs.

+"""
+Canonical reference implementation of the pr-management-stats dashboard.
+
+Per render.md, the dashboard MUST contain all 11 sections. This script
+is the agent-invocable fallback that guarantees no section is skipped.
+The skill remains the primary path; this script exists so that when
+agent context budget is tight, the maintainer can run a deterministic
+local render with full coverage.
+
+Usage:
+ reference.py --repo apache/airflow --viewer potiuk [--since 2026-04-12]
[--out dashboard.html]
+
+The script:
+ 1. Authenticates via gh (assumes `gh auth status` succeeds for the viewer)
+ 2. Fetches all open PRs with FULL engagement data (comments, reviews,
+ reviewThreads, timelineItems with LabeledEvent / ConvertToDraftEvent)
+ 3. Fetches closed/merged PRs since cutoff (default: 6 weeks)
+ 4. Fetches .github/CODEOWNERS + file paths for each currently-ready PR
+ 5. Classifies per classify.md (is_engaged uses ALL engagement signals)
+ 6. Aggregates per aggregate.md
+ 7. Renders per render.md — ALL 11 sections, no partial output
+
+Invariant: this script MUST render every section the skill specifies.
+If a section's data is unavailable, render a stub with an explanation,
+NEVER omit silently.
+
+See also:
+ - SKILL.md (entry point)
+ - classify.md (is_engaged, is_triaged, is_untriaged predicates)
+ - fetch.md (GraphQL templates)
+ - aggregate.md (all per-section computations)
+ - render.md (dashboard layout, recommendation rules, colour scheme)
