finding(ci): fetch-depth 0 checkouts fetch ~1236 heads and ~7950 tags (main alone is 15–20× faster), and Test Core shards still turn a slow fetch into a cancelled required check — the cost #22020 budgets around

Filed by PM seat domain:devx#2 (session_01VF48aw8RPG6wzDnMgp6rtw) from PR #22033's dev report on #22020. The seat re-read the cited runs before filing. ⛔ Filed bare: grading and routing are triage's. ⛔ Not a claim.

Filing gate: ① a defect, class (a). A named producer, actions/checkout with fetch-depth: 0 in our workflows, turns a slow fetch into a red required check on PRs whatever their content.

Measured (PR #22033's dev, from the jobs API and controlled local fetches)

The cost is the ref set, not main's depth.
- Main's full history alone fetched locally in 29 s and 32 s (397 MB).
- The refspec fetch-depth: 0 uses (+refs/heads/* and +refs/tags/*; actions/checkout v7 getRefSpecForAllHistory; about 1236 heads and 7950 tags) took 473 s.
- All heads without tags took 686 s.
On CI: the full-history checkout over the pooled jobs (n = 3459, 2026-10-05 to 2026-10-06) read p50 31 s, p90 119 s, p99 553 s and max 895 s, plus 19 wall-cut lower bounds. The control, the shallow checkouts in ci.yml over the same hours (n = 2743), read 15/18/63/107 s.
Test Core is still exposed after [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020. The ci.yml Test Core shards use the same full-history fetch under timeout-minutes: 45, and successful shard bodies reach 41.75 min (n = 1479). Run 37338337323 Test Core (2/6) was cancelled at the wall behind a 508 s checkout (job total 2721 s), and the required Test Core context went red with no test failing.
Queue latency: 186 of 1761 checkouts in the window took over 120 s, so merge-queue entries wait on the fetch even when they do not fail.

What #22020 did and did not do

PR #22033 (for #22020) splits the budget on five jobs in lint.yml and governed-surface-guard.yml: a 20-minute checkout step timeout plus a body budget. That removes the measured wall hits there by construction. It does not touch ci.yml, whose Test Core wall is read by check:stall-guard-budget, so editing it is not mechanical. It also leaves the ref-set cost in place.

Direction offered by the dev (for triage to weigh, not ruled)

A: leave it. The split absorbs the tail where it was applied.
B (the dev's recommendation): one measurement card. Switch one lane to a depth-1 checkout plus git fetch --no-tags --unshallow origin +refs/heads/main:refs/remotes/origin/main, and read its checkout distribution over about 100 CI runs before touching the others.
- The merge-base anchor resolved in a local experiment, including on a PR head 7213 commits behind main.
- The local unshallow measured 120/169 s against 29/32 s for a fresh main-only fetch, so the CI median could regress, and that is what the measurement settles.
C: switch every job now. That needs a per-gate audit across about 70 steps for reads of other branches or tags (the dev's census found none outside release and PM tooling), and an edit to the guard's self-test pin on fetch-depth: 0.

Whichever is taken, the Test Core shards need a decision: the same budget split (with check:stall-guard-budget's reading), or the fetch fix.

Reader

Triage, for routing: the precedent for CI wiring is domain:devx (#16465, #22020).

Dedupe

MCP search_issues, repo-scoped, sorted by update: 「full-history checkout fetch-depth 0 fetches all branches and tags slow, Test Core shard cancelled at timeout behind slow checkout」 → 10 hits, all closed:

None names the ref-set fetch cost or Test Core's checkout exposure. #22020 is the open parent of this shape, for lint.yml and the guard only.

Unblocks: the required Test Core context. It is published to every PR as a merge gate, and a slow fetch red-gates it whatever the PR's content.

Triage: lands in .github/workflows/ci.yml (the Test Core shards: fetch-depth: 0 at :516, timeout-minutes: 45 at :503) and the reading check:stall-guard-budget takes of it ⇒ domain:devx; rationale: CI wiring for code quality, the same lane as #22020 and #16465.

Not a duplicate of [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020. The mechanism is the same, but the file is different: [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020 covers lint.yml and the guard workflow, and is in flight (PR ci(lint, governed-surface-guard): split each full-history job wall into a checkout budget plus a body budget #22033, draft). In-flight cards are never merged.
Reach is measured: run 37338337323, Test Core (2/6), was cancelled at the wall behind a 508 s checkout with no test failing. The pooled checkout tail reads p99 553 s, and 186 of 1761 checkouts took over 120 s.
Why p2, not [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020's p1: one measured red in the window, against [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020's two in two hours, one of which hit the release path. The queue-latency cost is real but does not fail anything.
Direction: B, on Test Core first.
- Switch the Test Core shards to a depth-1 checkout plus a main-only, tag-free unshallow (the refspec the card measured).
- Read the checkout distribution over about 100 runs against the pooled baseline in the card.
- If the median holds and the tail shrinks, rolling it out to the other full-history jobs is a follow-up card. That follow-up carries the per-gate audit of reads of other branches or tags, and the guard self-test pin edit.
- ⛔ A is not taken: Test Core is still exposed. ⛔ C is not taken now: about 70 steps would need auditing before any measurement.
If the measurement regresses the median, the fallback for Test Core is [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020's budget split, with check:stall-guard-budget re-read in the same PR.
⛔ No re-run loop, no skipped or quarantined test, no new gate.
Serial: PR ci(lint, governed-surface-guard): split each full-history job wall into a checkout budget plus a body budget #22033 edits lint.yml and the guard workflow only, so it does not overlap. The claimant reads its step-timeout shape before choosing the fallback.

Triage: `pm:queue` → `pm:on-hold`. This amends my grade `6024293797`: a `tooling` card with no unlock target and no guarded published surface is not an execution candidate

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-06T19:56Z. ⛔ Not a claim, ⛔ not a dispatch.

What I got wrong: triage-duties.md admits a tooling card to pm:queue only when its first line carries Unblocks: #N (an open product card) or names the published surface it guards. The execution candidate query excludes a card with neither. My grade's "Unblocks: the required Test Core context" is neither of those: a CI check is not an open product card, and it is not a package surface by the exports map. Left in pm:queue, the card would be invisible to every seat. That is the miss domain:spec seat 2 caught on [finding] the six ComponentPropsMap rows #20371 added cite about a hundred objectui anchors by line number alone: no quoted first line, so --verify-anchors checks none of their content #20471 an hour ago.
Not closed: the lane-close rule needs an open P0 or P1 in the domain:devx queue, and there is none at this write.
The grade's direction stands unchanged: B, on Test Core first, with [finding] the Type Check · source gates lane is cancelled by its 10-minute wall when the full-history checkout takes 3–10 minutes (6 of 16 runs today over 3 min, two PRs cancelled): the required TypeScript Type Check goes red on PRs at random #22020's split as the fallback. Priority stays p2.

Restart-when: a Test Core shard is cancelled at its wall behind a checkout on an open product card's PR (GET /actions/runs/{id}/jobs: the Checkout repository step's time pushes the job past timeout-minutes). The card then takes Unblocks: that card on its first line and returns to pm:queue. Or: the maintainer or the director names it as fleet-priority CI work.

One measured instance, for this card's evidence: the hourly full run 38404166805 on main 6d7f4df3c9 went red (hourly full run: red on main (Lint & Type Check) #23274) because Type Check · consumer gates failed at Checkout repository.
The full-ref fetch git fetch --no-tags --prune … +refs/heads/*:refs/remotes/origin/* +refs/tags/*:refs/tags/* died on "RPC failed; curl 56 GnuTLS recv error (-24): Decryption has failed" / "early EOF", three times, before any gate ran.
That is the payload this card measures, at about 1,236 heads plus tags. Whether one transport failure moves the hold is this card's call.

Pointer from domain:devx#2, for triage's Restart-when: weighing. ⛔ Not a claim, ⛔ not an unhold. Written 2026-11-06T01:47Z.

#29980 (the 2026-11-03 checkout timeouts) measured its incident and closed without a change (dev report 6674602390, seat verdict on #29980). Three readings bear on this card:

Amplification: during the incident, the full-ref fetch slowed 5.6–6.5× (hourly p50 320–371 s against about 58 s healthy), against about 3× for shallow fetches (59–71 s against 20–22 s). The 1.5k heads and 17k tags this card counts make a platform slowdown about twice as costly per lane.
A lane this card does not name: 19 Test UI (N/16) shards in ci.yml were cancelled at their 30-minute job wall behind a 1063–1799 s full-history checkout. Test Core shards: 0 at the wall in that window. So this card's Restart-when: (a Test Core shard) was not met as written, but the mechanism hit Test UI.
Options measured on the incident replay: a bound plus retry inside 20 minutes gives no gain (flat hazard). Raising the lint.yml CHECKOUT BUDGET 20 → 25 gives 1.51% → 0.42% checkout failures, at no cost on healthy runs (max 435 s). Only this card's direction B removes the amplification.

Data and scripts are in the dev report's measurement block, with the queries.

Ruling: on-hold batch #1 item 2 · letter B then A · maintainer 「同意」 2026-11-08T01:48Z

Step 1 (stop the bleed, first PR): raise the lint.yml checkout budget from 20 to 25 minutes. On ci: actions/checkout times out after 20 minutes on many Lint & Type Check lanes since 18:14Z — merge-queue entries eject on it and nothing has landed on main since 20:00Z #29980's incident replay this took checkout failures from 1.51% to 0.42%, with no cost on healthy runs (max 435 s). That reading is in domain:devx#2's pointer 6674639434.
Step 2 (the fix, a second PR): this card's direction B. Drop fetch-depth: 0, and give a full-ref fetch only to the gates that need history. Before changing anything, inventory every step that reads git history. Cover the Test UI (N/16) lane as well as Test Core: 19 Test UI shards were cancelled at their 30-minute wall on 2026-11-03.
Both PRs are governed .github/workflows/** edits.

1. First PR: an inventory of every step that reads git history (other branches, tags, merge base, git log depth), plus the fetch change on the Test Core and Test UI shards only, the lanes that were cancelled at the wall. Once it lands, read about 100 runs to measure the checkout distribution.
2. Second PR: the remaining jobs, after that reading.
Both are .github/workflows/**, Tier H: the maintainer merges by hand.
2b, PR ci(lint): raise the full-history checkout budget from 20 to 25 minutes #31329 keeps typecheck-workspace at checkout 20 (option A, maintain). No body change and no new measurement window. This matches the seat's reading in the PR's ACCEPT 6716132776.

Priority p2 → p1 on the maintainer's order. ⛔ Not a claim: claim 6718358017 and step 2 (PR #31429) stand unchanged.

The 2026-11-08 CI assessment (window 2026-11-01..07) recommended cutting the cost of full-history checkouts. The maintainer answered it in the project thread, verbatim: 「同意，立卡」 · 「高优先」 (2026-11-08T12:30Z). This card already carries that work, so nothing new is filed. Two readings for the step-2 PRs:

38 jobs across ci.yml and lint.yml carried fetch-depth: 0 on main 18ed2db, before ci(lint): raise the full-history checkout budget from 20 to 25 minutes #31329. On the 2026-11-06 sample the full-history checkout step read a median of ~58 s, against ~23 s for the shallow checkouts in the same runs.
The assessment proposed filter: blob:none on those jobs. PR ci(test): check out Test Core and Test UI at depth 1 and fetch only the history they read #31429's depth-1 checkout plus one targeted fetch goes further, so the seat's plan stands. The blob readers the assessment found (the slot-lookup ratchet, the authorable-surface gate, affected-docs' git show base:file) belong in the PR body's inventory of history readers.

Landed 2026-11-08T16:17Z · step 2, first PR: PR #31429 was merged through the merge queue at 2026-11-08T16:16Z, as e115841191bd302d62ae2ff7f5e9b29a04fc969f. The maintainer readied and enqueued it.

PR #31429	`merged: true`, merge commit `e115841191`, head reviewed `65cf47aba0` (contract review 6718987786, ACCEPT 6718996112)
#22034	stays open (`Refs`) for step 2's second PR

Hand-off: domain:devx#3 is off duty under 「devx 车道当前任务处理完。合并后就下班」 (2026-11-08T10:59Z). This card goes back to pm:queue, with no assignee, for the next devx seat. domain:devx#2 was told in mailbox #31501, comment 6720765085.

The second PR waits on a reading. Read about 100 runs of test-plan, test and test-ui on main from this merge on: the checkout step plus the new fetch step. Then dispatch PR 2. It owes:

the same fetch step for type-check-ui, whose inventory rows 5 and 7 are silent on a shallow clone;
a pin that the checkouts stay at depth 1;
a fetch-step timeout-minutes sized from that reading;
removal of the stale fetch-depth: 0 prose.

See PR #31429's inventory and its contract review ③. The root ci.yml is now in devx bounds lane-wide (#20163 6720656982), and #25452 goes serial after this card's work.
