From 5b53ed1efa8cfa0f95d00d33fda04cf21edeac8a Mon Sep 17 00:00:00 2001 From: Zach Vorhies Date: Sun, 4 Oct 2026 20:46:13 -0700 Subject: [PATCH 1/8] ci(cache): add a ci.toml declaring FastLED/fbuild's cache ceiling fbuild had no ci.toml, so nothing bounded its Actions cache: 43 entries totalling 8.73 GiB, 87% of GitHub's 10 GiB cap, with no declared family and no janitor budget. This adds a cache-only policy. Every max is at or above the largest entry measured live on 2026-10-05, and every max x cardinality product is at or above that family's measured live total, so ci-lint cache janitor's LRU trim cannot truncate a live cache. Declared families (measured): compile/build-cache 19 entries 7883 MB, dylint 1 entry 618 MB, registry 2 entries 503 MB, solo-toolchain 2 entries 359 MB, soldr-mini 1 entry 11 MB. Static CACHE-004: worst 9751756800 B <= budget 10200547328 B (9.5GB). Not declared: setup-soldr's thin target cache (18 entries, 3.7 KB total) -- ci-lint has no via value for that prefix, and it costs no budget. [cache.promote] mode = "off": nearest-ancestor promotion is not released. No [local.gate.*] keys: fbuild ships no local-gate.toml and no declared local gate, and a partial [local.gate] would make ci-lint local-gate demand a complete one.

Soldr builds musl AND gnu per Linux arch. That exposed a worse problem. With the real cardinality of 8, `max x cardinality(per)` = 1300 MB x 8 = 10.4 GB, over the 10 GB cap -- but NO live entry corresponds to a gnu target at all. The 19 live entries are 19 distinct WRITER SHAPES, and only one names a target triple. So `per = "platform"` was never modelling reality; it modelled writer shapes as platforms and happened to land under budget. Replaced with `shapes` (schema 3, zackees/ci.yml#334), one ceiling per measured writer shape: compile now models 6.35 GB against 7518 MB measured live, and the janitor's LRU budget stays at or above real bytes so it cannot delete a live cache. An earlier comment on this family claimed schema 3 lacked a job- shape axis; it has had one since #334.

From a4313118dc3c91d732aaeaf7773ce78a878da871 Mon Sep 17 00:00:00 2001 From: Zach Vorhies Date: Mon, 5 Oct 2026 03:25:37 -0700 Subject: [PATCH 3/8] ci(gate): suppress CodeRabbit's PR gating per GATE-012 CodeRabbit runs on GitHub's servers and cannot run under the local gate, so per policy-general.md "Remote-only checks never gate a PR" it must not be able to block a merge. Its findings remain useful as PR comments; only the gating is disabled. This was a live GATE-012 violation, not a theoretical one: CodeRabbit's CHANGES_REQUESTED review held #1652 at BLOCKED with all 20 checks green, and because `reviews.request_changes_workflow: true` the block could not be cleared by the fixes it asked for alone. `ci-lint remote-only --repo .` now reports 0 violations.

Wire a real "ci-lint cache preprune --lockfile-changed" into every push-to-main saving path, per zackees/ci.yml#354's structural rule (same run: same job or an earlier needs: link; GitHub Actions has no cross-workflow barrier): - ci-minimal "verify": linux (the check-ubuntu call, both of whose jobs save on main) already needs verify -- the prune is appended there. Generator render_local_gate_verify() + regenerate. - nightly-platforms "plan": fbuild_bin already needs plan -- the prune is appended there. Generator render_nightly() + regenerate. - dylint / benchmark-build-comparison / fmt: the only saving job in each run; prune steps sit directly ahead of setup-soldr. - template_build: nightly-dispatched board runs save on main; the step gate mirrors setup-soldr's save-cache gate (ref == main). New ci/lockfile_changed.py copies zackees/template-python-rust-cmd's convention: the prune runs only on pushes that touched Cargo.lock, uv.lock or rust-toolchain.toml, and treats an unavailable HEAD^ conservatively as changed. ci.toml: [allow.permissions] gains "actions: write" for the six prune jobs (SEC-002); [allow].actions gains actions/checkout so the prune jobs' ci.yml checkout (at the linter pin, CT-004, 40-hex per SEC-004) is allowlisted. .gitignore gains /.ci-lint/ for template_build's stray-working-tree assertion. precheck --local before/after: CACHE-034 1 -> 0; CACHE-004 arithmetic identical (worst 7921991680 B <= budget 10200547328 B); zero new findings -- only removals (SEC-004 220 -> 182 via the allowlist). render_workflows --check, check_workflow_concurrency and check_no_legacy_cross pass locally. --- .../workflows/benchmark-build-comparison.yml | 28 ++++++++ .github/workflows/ci-minimal.yml | 21 +++++- .github/workflows/dylint.yml | 29 +++++++++ .github/workflows/fmt.yml | 28 ++++++++ .github/workflows/nightly-platforms.yml | 18 +++++ .github/workflows/template_build.yml | 31 +++++++++ .gitignore | 5 ++ ci.toml | 13 +++- ci/lockfile_changed.py | 65 +++++++++++++++++++ ci/render_workflows.py | 63 +++++++++++++++++- 10 files changed, 297 insertions(+), 4 deletions(-) create mode 100644 ci/lockfile_changed.py diff --git a/.github/workflows/benchmark-build-comparison.yml b/.github/workflows/benchmark-build-comparison.yml index de6da152..6679d5f1 100644 --- a/.github/workflows/benchmark-build-comparison.yml +++ b/.github/workflows/benchmark-build-comparison.yml @@ -33,13 +33,41 @@ jobs: name: Measure and publish Blink builds runs-on: ubuntu-24.04 timeout-minutes: 60 + # CACHE-034 (zackees/ci.yml#352/#354/#360): this job runs the pre-prune + # ahead of its own setup-soldr save; `actions: write` is what the cache + # deletions need (allow-listed in ci.toml's [allow.permissions]). + permissions: + contents: read + actions: write steps: - uses: actions/checkout@v6 with: persist-credentials: false + # HEAD^ must exist for ci/lockfile_changed.py (CACHE-034). + fetch-depth: 2 - uses: astral-sh/setup-uv@v3 + # CACHE-034 (zackees/ci.yml#352/#354/#360): honour [flow.main]'s + # `pre-prune = true` waiver.

Two environment facts make the replay diverge from real CI: - bosn's source snapshot has no HEAD^, so ci/lockfile_changed.py takes its conservative branch and reports changed=true; - with no secrets, the prune step runs and then fails on missing creds. On real GitHub both differ: fetch-depth 2 gives HEAD^, and the token is always present. Add `github.token != ''` to the prune step's condition in all six wiring sites, so a secretless local replay skips the step while every real run still executes it.

Two changes make it execute successfully in both worlds: - GITHUB_TOKEN gains a `github.token || 'replay-no-token'` fallback at all six sites. Replays inject no secrets, so the fallback token reaches the GitHub API, gets a 401, and ci-lint reports its "could not list live caches" warning with exit 0 -- a real executed-successful section. Real GitHub runs always resolve github.token and are unaffected. - dylint.yml's prune drops its non-PR event gate: that workflow's own gate replay is a pull_request selection (the step must be runnable there), and dylint saves caches on PRs anyway (save-cache: true), so pruning on lockfile-touching PRs matches what the job writes. The gate remains the lockfile change itself. The previous `github.token != ''` guard is removed as redundant. Gate unit tests, render_workflows --check, check_workflow_concurrency, YAML parse and precheck --local all unchanged (CACHE-034 still 0, findings identical to the verified after-state). --- .../workflows/benchmark-build-comparison.yml | 7 +++++-- .github/workflows/ci-minimal.yml | 7 +++++-- .github/workflows/dylint.yml | 10 +++++++-- .github/workflows/fmt.yml | 7 +++++-- .github/workflows/nightly-platforms.yml | 7 +++++-- .github/workflows/template_build.yml | 7 +++++-- ci/render_workflows.py | 21 ++++++++++++------- 7 files changed, 47 insertions(+), 19 deletions(-) diff --git a/.github/workflows/benchmark-build-comparison.yml b/.github/workflows/benchmark-build-comparison.yml index 26b438b5..559441fb 100644 --- a/.github/workflows/benchmark-build-comparison.yml +++ b/.github/workflows/benchmark-build-comparison.yml @@ -64,9 +64,12 @@ jobs: id: lockfile run: python3 ci/lockfile_changed.py - name: Pre-prune superseded lockfile-keyed caches (CACHE-034) - if: github.event_name != 'pull_request' && steps.lockfile.outputs.changed == 'true' && github.token != '' + if: github.event_name != 'pull_request' && steps.lockfile.outputs.changed == 'true' env: - GITHUB_TOKEN: ${{ github.token }} + # act2/bosn replays inject no token: the fallback keeps the + # step runnable there (401 -> ci-lint warning, exit 0);

Detection stays exact in both directions: the peak term enters the forecast precisely when the lockfile changed (or the diff failed conservatively), while an unflagged run is forecast-only and never deletes (steady total is under budget). No control operators enter the run line, so GEN-005's shell budget is unaffected.
