Summary

Closes #1564.

main-red-watchdog was filing phantom [main-red] issues because Gitea maps both action_run.status=2 (Failure) and status=3 (Cancelled) to commit-status string "failure". On a busy main with concurrency: cancel-in-progress: true, every merge burst cancels prior in-flight runs (status=3), inflating the watchdog's red%.

This PR implements option B from #1564 (description-string filter, no extra API call): is_red() excludes per-entry items whose description == "Has been cancelled" (the literal Gitea description for cancelled runs; real failures carry "Failing after Ns").

Verified empirically against mc#1562 body — that issue contains 3 real failures (Failing after 8s/1m49s/1m21s) + 1 cancel-cascade (Has been cancelled). With this filter, mc#1562 would have filed with only the 3 real failures (correct), and a pure-cancel-cascade SHA would not file at all.

Canonical Gitea 1.22.6 enum

Per models/actions/status.go:

1=Success, 2=Failure (real defect, file), 3=Cancelled (concurrency artifact, ignore),
4=Skipped, 5=Waiting, 6=Running, 7=Blocked

Source: operator memory reference_gitea_action_status_enum_corrected_2026_05_19 + reference_chronic_red_sweep_cancelled_vs_failed_filter (saved during mc#1529 triage).

Behaviour change

is_red() now drives red off the filtered failed list, not raw combined-state. Combined=failure with all-cancelled per-entry → not red. Combined=failure with empty statuses[] is preserved as red (the CI-emitter-direct edge case from render_body's existing fallback).

Exact-match (not substring) so a hypothetical real-failure log line containing "Has been cancelled by ..." still counts as red.

Out of scope

• Does NOT close phantom issues retroactively (per #1564 — separate cleanup).
• The Platform (Go) sqlmock failures on ci.yml (18 in 7d, real status=2) remain to file separately once root-caused.

Test plan

• 6 new unit tests in tests/test_main_red_watchdog.py covering: cancel-cascade alone (not red), real-failure alone (red), mixed (red, only real in body), all cancelled (not red), combined+empty fallback (still red), exact-match contract.
• All 36 tests in tests/test_main_red_watchdog.py pass locally (Python 3.13).
• Required CI contexts green on this PR.
• First post-merge cron tick (:05) observed on real main — confirm no new phantom [main-red] issue files when only cancel-cascade present.

## Summary Closes #1564. `main-red-watchdog` was filing phantom `[main-red]` issues because Gitea maps **both** `action_run.status=2` (Failure) and `status=3` (Cancelled) to commit-status string `"failure"`. On a busy `main` with `concurrency: cancel-in-progress: true`, every merge burst cancels prior in-flight runs (status=3), inflating the watchdog's red%. This PR implements **option B from #1564** (description-string filter, no extra API call): `is_red()` excludes per-entry items whose `description == "Has been cancelled"` (the literal Gitea description for cancelled runs; real failures carry `"Failing after Ns"`). Verified empirically against mc#1562 body — that issue contains 3 real failures (`Failing after 8s/1m49s/1m21s`) + 1 cancel-cascade (`Has been cancelled`).

fix(ci): main-red-watchdog skips cancel-cascade entries — closes #1564 ... fcf08647c5

Gitea maps BOTH `action_run.status=2` (Failure) AND `status=3` (Cancelled)
to commit-status string `"failure"`. On a busy `main` with
`concurrency: cancel-in-progress: true`, every merge burst cancels prior
in-flight runs (status=3) — those bubble to the combined-status `failure`
rollup and inflate the watchdog's red%, generating phantom `[main-red]`
issues (mc#1562/#1552/#1540/#1532/#1527/#1526/#1522/#1503/#1487/#1484).

Per mc#1564 the cleanest filter at this layer is option B (description
string): cancelled-run entries carry description `"Has been cancelled"`,
real failures carry `"Failing after Ns"`. is_red() now excludes the
former from the failed[] list, and combined=failure alone (no per-entry
detail) only trips red when statuses[] is empty (the CI-emitter-direct
edge case from render_body's existing fallback).

Match is description == "Has been cancelled" exactly (after strip), not
substring, so a hypothetical real-failure log line containing that
phrase still counts as red.

Canonical Gitea 1.22.6 enum per `models/actions/status.go`:
  1=Success, 2=Failure, 3=Cancelled, 4=Skipped,
  5=Waiting, 6=Running, 7=Blocked
(reference: operator memory
 reference_gitea_action_status_enum_corrected_2026_05_19
 + reference_chronic_red_sweep_cancelled_vs_failed_filter)

Tests (6 new, all 36 in suite pass locally):
  - cancel-cascade entry alone → not red
  - real-failure entry alone → red (no over-filter)
  - mixed cancel + real → red, failed[] contains only real failures
  - all entries cancelled → not red (the phantom-issue case)
  - combined=failure + empty statuses[] → still red (preserve fallback)
  - exact-match contract (substring would over-match)

  - mc#1529 (chronic-red triage that surfaced this)

5-axis (core-security):

1. Secrets: None handled. The watchdog reads Gitea status payloads; description-string match is a literal compare.

2. Privilege: No new surface — same combined/statuses[] read shape. The cancel-cascade filter strictly NARROWS what counts as red (fewer issue-files), so least-privilege effect.

3. Input handling: Description-string match uses exact compare after .strip() — explicitly rejects substring (the over-match test locks this contract: "Has been cancelled by the user unexpectedly" stays red). No regex eval surface.

4. Trust boundary: Test coverage is comprehensive (6 new tests including the empty-statuses fallback edge — preserves the "combined=failure with no per-entry detail" breadcrumb path for the CI-emitter-direct case).

5. Supply-chain: Pure Python stdlib. No new deps.

APPROVE.

5-axis (core-qa):

1. Test-driven fix: 6 new tests covering the cancel-cascade filter — exact-match contract, mixed-cancel-and-real, all-cancel green, real-failure preservation, empty-statuses fallback, and the over-match guard. Each test cites the corresponding memory entry.

2. Canonical alignment: Matches reference_chronic_red_sweep_cancelled_vs_failed_filter — filter must exclude status=3 from BOTH numerator and denominator. Verified description-string contract "Has been cancelled" (Gitea 1.22.6).

3. Edge coverage:

   • Pure cancel-cascade → green (mc#1562/#1552/#1540 phantom issue prevention).
   • Mixed entries → red but failed[] list contains only real failures (clean issue body).
   • Combined=failure + empty statuses[] → still red (CI-emitter-direct breadcrumb preserved).
   • Substring over-match guard (locks down exact-match contract).

4. Forward-compat: Header documents that if Gitea renames the description string in a future release, cancel-cascade entries simply leak back through (visible-not-silent). Option A (resolve action_run.status integer via target_url) documented as escalation path.

5. Reversibility: Pure filter narrowing; if it over-filters, real failures are still seen via combined-status fallback path.

APPROVE.
