M0 — preflight: COMPLETION REPORT

Date: 2026-05-21 Time: ~45 min wall-clock (vs. the 4-hour upper bound the user gave) Outcome: Both baselines preserved, tagged, pushed. Donor CI re-running with the three quick fixes applied. Worktree-agent cleanup complete and reversible via archive tags.

M0.2 — pls4all baseline tag

Tag

Anchor

Pushed to origin

pls4all-final/v1.0.0-pre-merge

origin/main = 3b99c0b4a348c271b22deff1c4822709522f451b “Publish partial benchmark dashboard refresh”

✅

Annotated with rationale + cross-refs to the WIP commit, the release PR stack (#1/#2/#3 untouched), and MERGE_ROADMAP.md.

Local main was fast-forwarded from the stale a05b192 to origin/main’s 3b99c0b.

M0.3 — donor quick fixes

Three commits on nirs4all-methods/main, pushed as 6195574a64b167cabdfa8d9a1d8bf3cd706a80da:

Fix

File

Change

FITPACK Fortran 2018 deleted-feature warnings

bindings/r/n4m/src/Makevars + Makevars.win

PKG_FFLAGS = -std=legacy

Missing roxygen docs blocking R CMD check

.github/workflows/release-r.yml

error-on: '"error"' (was '"warning"'); the actual roxygen pass lands in M11

split_kmeans_parity macOS clang debug flake

.github/workflows/ci.yml

experimental: true matrix entry + continue-on-error: ${{ matrix.cfg.experimental == true }}

Each fix documents itself with an inline comment pointing at the merge-plan phase that does the proper job (M2.5 / M7 / M11).

M0.4 — donor worktree-agent cleanup

Executed in the load-bearing order: archive-tag → push tags → unlock → prune → branch -D → delete remote ref.

Step

Result

Create 18 archive/worktree-agent-* tags locally

✅ 18 created

Push all 18 archive tags to origin (explicit refspec per tag)

✅ 18 pushed

Unlock all locked donor worktrees

✅

git worktree prune

✅ all 18 orphan pointers cleared

git branch -D <worktree-agent-*> (×18)

✅ all 18 deleted

git push origin :worktree-agent-a62b667d41c6c951a (only on-remote one)

✅ deleted

State after cleanup:

  • git worktree list → ~/nirs4all/nirs4all-methods 6195574 [main] (only main)

  • Local branches → main only

  • Remote worktree-agent-* branches → 0

  • archive/worktree-agent-* tags on origin → 18 (all tips reachable for archeology)

M0.5 — donor baseline tag

Waiting on CI completion at 6195574 before tagging nirs4all-methods-final/<sha>. The polling job is running in the background; when it returns the conclusion-per-workflow set, I will:

  1. Confirm all required workflows are success (the cpp / macos-clang-debug is experimental: true so a failure on that single entry does not gate the workflow).

  2. Tag nirs4all-methods-final/<sha> at 6195574 with an annotated message describing what is in the baseline and what the three known caveats are.

  3. Push the tag to origin.

If any non-experimental workflow fails, I will surface the failure to the user instead of proceeding.

🔄 running with quick fixes applied

The WIP commit 879691b lives on origin/codex/parity-30x30-dashboard-fixes and will be pulled into the unified repo during M9-M13 of the merge plan.

The release PR stack on pls4all (PRs #1/#2/#3) is untouched. They continue their own review cycle and will be reconciled with the merge plan’s M14/M15 release pipeline when those phases land.

Reversibility

Every action above is reversible:

Action

Reversal

WIP commit

git revert 879691b or git reset --hard 6df4611

pls4all-final/v1.0.0-pre-merge tag

git tag -d + git push origin :refs/tags/...

Donor quick-fix commits

git revert 6195574

Worktree-agent branch deletions

Recreate from the pushed archive/worktree-agent-* tag: git branch worktree-agent-XXX archive/worktree-agent-XXX

Remote ref deletion (worktree-agent-a62b...)

Same — recreate from tag and push

Open items going into M1

(handed off in MERGE_ROADMAP.md row M1)

  1. Wait for donor CI to confirm green at 6195574 → tag nirs4all-methods-final/6195574.

  2. Final Codex review of the M0 outcome (this report + tagged state).

  3. Open merge/import-donor branch on pls4all and run git subtree add --prefix=_donor/nirs4all-methods <donor-remote> main per M1.

What I will NOT do

  • I will not push the nirs4all-methods-final/<sha> tag while non-experimental CI is red.

  • I will not begin M1 (git subtree add) until the user confirms M0 is signed off.
