ci: Turbo seeds vs the 10 GB Actions cache pool — measure the pool, then shrink or retire the per-sha seeds #25452
Description
Filing gate: ② ruling-directed sibling card — batch #5 item 1, letter C (#25373 comment 6366946328, maintainer 「同意」 2026-10-23T14:13:20Z). Reader: the domain:devx execution seat, dispatch step. Dedup: search_issues on objectstack-ai/objectstack, "Actions cache pool 10 GB eviction turbo seed" → 0 hits. Session: cse_01LKHDniRQSWjRJyDtacwpEd.
One-sentence problem
Every push to main writes about 12.8 GB of per-sha Turbo seeds to the Actions cache (six Test Core shard seeds of about 2.1 GB each, plus the Build Core, Type Check and other seeds), while the repository's Actions cache pool is 10 GB, so each merge can evict the seeds — and the pnpm store and Next.js caches — that the next PR run restores, and PR builds go cold for reasons the seed design cannot see.
Evidence (file lines at objectstack commit 2b7c331)
- Per-sha seed keys, saved on every push event, including cancelled runs (
if: always() && github.event_name == 'push'):ci.yml:1397-1402(Test Core, per shard),ci.yml:2242-2247,ci.yml:2749-2754(Build Core),lint.yml:5928-5930(typecheck). Keys end in${{ github.ref_name }}-${{ github.sha }}(ci.yml:606,:1786,:2087,:2320,:2529,:2974;lint.yml:5140,:5753), so no two merges share a key and nothing is overwritten — every merge adds a full set. - Cancelled push run 39923516471 saved all six Test Core shard seeds at about 2.1 GB each (the ci: the push-to-main CI run is cancelled by the next merge 9 times in 13, so the Turbo cache seed that only that run saves goes stale and every PR shard and lint lane rebuilds cold (Build Core 51 s → 4m30s, shard closures Σ 20–31 runner-min per run) #25373 card thread's falsification, comment 6364570166).
- Plain
actions/cache@v6steps (restore and post-save on every event, PRs included) sit in 12 workflow files;ci.yml:2785-2798saves the pnpm store andapps/docs/.next/cacheon PR runs too. PR-scoped entries count toward the same pool. - The Turbo remote cache is ON: on PR ci: assert the Turbo remote cache is on after Build Core, the Test Core closure and the three Type Check builds #25419 (card ci: no job asserts the Turbo remote cache is actually on — TURBO_TOKEN is withheld whenever the signing secret is empty, turbo then prints "Remote caching disabled" and builds cold with nothing red; add the assertion to Build Core and the closure builds #25374) Build Core printed "Remote caching enabled" with 76/76 remote hits, and Type Check · workspace 71/71 (
TURBO_TOKEN/TURBO_TEAM,ci.yml:749-750). For the tasks the remote cache serves, the per-sha.turbo/cacheseed in the Actions pool may be redundant weight. - Pool usage is NOT measured yet.
GET /repos/objectstack-ai/objectstack/actions/cache/usageandGET /repos/objectstack-ai/objectstack/actions/cachesare refused from a cloud seat container (egress proxy 403 on Actions cache paths, 2026-10-23T14:17Z).
Governing text
ci.yml:597-610andlint.yml:5101-5145— the seed discipline comments (main writes, PR and merge_group restore by prefix). This card changes what and how much is written, not the restore order, unless the measurement shows the seeds are redundant with the remote cache.- AGENTS.md lines 371–372 are about the local worktree cache, not CI.
- Ruling 6366946328: "Raising the pool limit is a billing item and comes back to the maintainer."
Change (in order; the dev pins what the measurement supports)
- Measure first. Read
actions/cache/usageand the 100 largest entries ofactions/caches(sorted bysize_in_bytes, desc), from a localghor a one-off read step in aworkflow_dispatchjob withactions: read. Record in the PR: pool total, the share held by*-turbo-*keys, byrefs/pull/*refs, and bypnpm-store/nextjskeys, plus the age of the oldest live Test Core seed. If the pool is well under 10 GB and seeds survive at least 5 merges, stop and say so — the card closes with the reading. - Then shrink, cheapest first, choosing from: (a) drop the
.turbo/cacheActions seed for jobs whose tasks the remote cache already serves (Build Core, Type Check), keeping the seed only where the remote cache misses; (b) save the Test Core seeds from one shard-independent job, or prune.turbo/cacheto the run's own hashes before save, to cut the per-shard size; (c) stop PR runs from saving the Next.js cache (restore-only on PRs, as the Turbo seed already is). - Never raise the pool limit in this card. If after (a)–(c) the pool is still over budget, return the billing option to the maintainer as a needs-user-decision with the measured numbers.
Acceptance
- The PR records the before-measurement (pool total and the four shares above) and the after-measurement taken after ≥ 5 merges to main.
- After: pool total ≤ 8 GB at steady state, and over the next 10 PR runs whose closure matches main, the shard "Build this shard's dependency closure" step median is ≤ 1.7 min and Build Core's build step is ≤ 2.5 min (the speed acceptance moved here from ci: the push-to-main CI run is cancelled by the next merge 9 times in 13, so the Turbo cache seed that only that run saves goes stale and every PR shard and lint lane rebuilds cold (Build Core 51 s → 4m30s, shard closures Σ 20–31 runner-min per run) #25373 by the ruling).
- Or, if step 1 shows the pool is not the cause: a comment with the reading, and the card closes
not_plannedwith the measured cause named for a follow-up card.
Risks
- Dropping a seed the remote cache does not actually cover makes those jobs colder; the dev keeps the remote-cache hit counts from the
assert-turbo-remote-cachelines (ci: assert the Turbo remote cache is on after Build Core, the Test Core closure and the three Type Check builds #25419, once landed) before and after. - Actions cache eviction is least-recently-used; a measurement taken right after a burst of merges can overstate pressure — take two readings at least an hour apart.

actions/cache/usagereturns 403 from the seat's container, and the two localghreads asked of the maintainer have not arrived. On the arithmetic, about 0.27 GB per full merge leaves the 10 GB pool more than 30 merges of headroom. But the old 2.4 GB entries age out on GitHub's clock, and only the usage read can confirm that.The seat recommends closing #25452 once the pool read is in. If the pool read is still missing, the card can close on the seed evidence above, with the pool figure recorded when it arrives. That choice is the maintainer's.
