Tom Boucher b8d9bd69b2 fix(release-sdk): skip all cherry-pick conflicts in hotfix loop (full automation) (#2970)
* fix(release-sdk): skip all cherry-pick conflicts in hotfix loop

Full-automation policy: any conflict the cherry-pick can't auto-resolve
— context-missing (#2966) or real merge conflict — is now skipped, not
aborted. The hotfix run completes with whatever applies cleanly; the
SKIPPED list in the run summary becomes the operator's post-hoc review
queue.

Surfaced in run 25227493387 (1.39.1 dry-run): commit 0fb992d
("fix(git): add git.base_branch config") produced real conflicts in
config.cjs / ship.md / complete-milestone.md / tests/config.test.cjs.
v1.39.0 was tagged on the feat/hermes-runtime-2841 branch (#2920),
which restructured those files. 0fb992d was authored against the
pre-restructure shape, so cherry-pick can't auto-resolve.

Pre-#2968 behavior: the workflow distinguished context-missing (skip)
from real (abort + push partial + exit 1). Real conflicts blocked every
hotfix from a base tag whose lineage diverged from main — exactly the
v1.39.x situation. The user has called explicitly for full automation:
"this needs to be fully automated, no one is going to sit there and
tag fixes."

Behavior change:
  - Both classification branches now `git cherry-pick --skip` and
    append to SKIPPED with a reason category:
      * "context absent at base" — empty-HEAD markers (#2966)
      * "merge conflict — manual review" — non-empty HEAD (#2968)
  - Removed: `git cherry-pick --abort`, partial-state push,
    "Cherry-pick conflict" GITHUB_STEP_SUMMARY block, `exit 1`.
  - Operator's manual recovery path via `auto_cherry_pick=false`
    remains intact.

Trade-off (acknowledged in #2968): a critical fix can be silently
dropped if no one reviews the SKIPPED list. The release job's
install-smoke + full test suite still runs and would catch any
test-covered regression. Fixes that aren't test-covered could ship
missing — accepted cost of full automation per the issue.

Tests:
  - tests/bug-2968-cherry-pick-skip-on-any-conflict.test.cjs (new) —
    extracts the cherry-pick failure block via bash if/fi nesting walk
    (no raw-text grep) and asserts the abort path is removed, --skip
    is unconditional, and "merge conflict" + "context absent at base"
    annotations both exist.
  - tests/bug-2966-cherry-pick-context-missing.test.cjs (renamed
    describe + first test name) — assertions still valid since the
    classifier survives for skip-reason annotation.
  - tests/bug-2964-release-sdk-empty-cherry-pick.test.cjs — unchanged
    and still green.

Local: `node --test tests/bug-2964-...test.cjs tests/bug-2966-...test.cjs
tests/bug-2968-...test.cjs` → 8/8 pass.
Local: `npm run lint:tests` → 0 violations.

* fix(release-sdk): split cherry-pick conflict skips from policy skips

CodeRabbit flagged on PR #2970 that conflict skips and policy skips
share the SKIPPED bucket. The run summary heading
"Skipped (feat/refactor/etc — not auto-included)" buries manual-review
conflicts (which the operator must triage) under the same list as
intentional policy exclusions (commits that don't match fix/chore by
design and need no action). Operators reviewing the summary can't
distinguish the two without reading every entry.

Split into two variables:
  - POLICY_SKIPPED — feat/refactor/docs/etc filtered out by the
    fix/chore regex (informational, no action needed)
  - CONFLICT_SKIPPED — fix/chore commits whose cherry-pick failed and
    were skipped per the full-automation policy (#2968) (manual
    review queue)

Run summary now emits two sections with distinct headings:
  - "Skipped — cherry-pick conflict (manual review)"
  - "Not auto-included (feat/refactor/docs/etc)"

The new bug-2968 test asserts both buckets are populated correctly:
  - failure path appends to CONFLICT_SKIPPED, not SKIPPED
  - both bucket variables are echoed in the summary
  - both section headings are present

Local: `node --test tests/bug-2964-...test.cjs tests/bug-2966-...test.cjs
tests/bug-2968-...test.cjs` → 9/9 pass.

* fix(release-sdk): handle merge commits and guard cherry-pick --skip

CodeRabbit flagged a real major issue on PR #2970: merge commits with
fix:/chore: titles fail BEFORE entering cherry-pick state because they
need `-m <parent>` to specify the diff base. Without it, the cherry-pick
errors out and CHERRY_PICK_HEAD is never created. The unconditional
`git cherry-pick --skip` call that follows then fails too (no in-progress
cherry-pick to skip), bricking the loop — defeating the full-automation
policy this PR set out to deliver.

Two guards added:

1. Pre-skip merge commits before invoking cherry-pick. The loop checks
   parent count via `git rev-list --parents -n 1 "$SHA"`; if > 1, the
   commit goes straight to CONFLICT_SKIPPED with reason "merge commit —
   manual -m parent selection required". Operator decides which parent
   to keep when reviewing the run summary.

2. Guard `git cherry-pick --skip` with a CHERRY_PICK_HEAD existence
   check. Catches any other failure mode where the cherry-pick aborts
   before entering conflict state (unreadable commit, ref problems,
   etc.) so the loop still continues cleanly.

Also bumped the bug-2964 test's regex slice window from 2000 to 4000
chars so the merge-commit pre-skip block doesn't push the cherry-pick
line out of the test's match range.

Tests added in tests/bug-2968-cherry-pick-skip-on-any-conflict.test.cjs:
  - merge-commit detection: workflow must call
    `git rev-list --parents -n 1 "$SHA"` before cherry-pick and annotate
    skips with the distinct "manual -m parent selection required"
    reason.
  - guard: failure block must check CHERRY_PICK_HEAD before --skip.

Local: `node --test tests/bug-2964-...test.cjs tests/bug-2966-...test.cjs
tests/bug-2968-...test.cjs` → 11/11 pass.

* fix(release-sdk): guard awk classifier against degenerate unmerged paths

CodeRabbit raised two issues on PR #2970:

1. Major (workflow): the `awk` classifier runs under `set -euo pipefail`.
   If a CONFLICTED path is missing/unreadable, awk exits non-zero and
   terminates the entire step — bricking the loop on a degenerate file.
   Also, an unmerged path with no `<<<<<<< ` markers (path-level conflict
   or anomalous git state) was misclassified as "context absent at base"
   (the auto-skip path), letting potentially-real conflicts skip silently.

   Fix: before invoking awk, check `[ ! -r "$CONFLICTED" ]` and
   `grep -q '^<<<<<<< ' "$CONFLICTED"`. Either failure marks
   ALL_EMPTY_HEAD=false → REASON falls through to "merge conflict —
   manual review", landing the pick in the operator review queue.
   Also added `2>/dev/null || echo "real"` on the awk call so a
   transient awk failure can't slip into the auto-skip bucket.

2. Nitpick (tests): regex assertions on `failureBlock` could match
   commented lines (e.g. comment text mentioning "CONFLICT_SKIPPED"
   or "git cherry-pick --skip" satisfied the assertions without the
   real command being present).

   Fix: anchor with `^\s*...` + `m` flag so only executable shell lines
   count.

Plus a new test asserting all three workflow guards
(`[ ! -r "$CONFLICTED" ]`, `grep -q '^<<<<<<< '`, `awk ... || echo
"real"`) are present in the failure block.

Local: `node --test tests/bug-2964-...test.cjs tests/bug-2966-...test.cjs
tests/bug-2968-...test.cjs` → 12/12 pass.
