test: cover promote.rs's budget/render/deadline/overloaded refusal branches - #668
Conversation
…anches Refs #627 - budget_refusal (per-batch deadline check mid-apply-loop) - render_refusal's Timeout arm (deadline dying inside export::render, before the apply loop even starts) - audit_skip_reason's deadline_exceeded (destination vocabulary large enough to make the lexical twin sweep outlast the budget) - audit_skip_reason's overloaded (a concurrent promotion holding the only TAGURU_MAX_CONCURRENT_HEAVY_OPS permit) metadata_unreadable and no_context are scoped out: apply_batch unconditionally retracts the destination's whole passage store on every batch, so a corrupted/vanished destination always fails the WRITE phase before landing_audit is ever reached — confirmed empirically, both with and without the promoted batch itself carrying passage content.

COUNT = 600とTAGURU_REQUEST_TIMEOUT_SECS=1の組み合わせは、実行環境の速度に依存します。低速な CI では最初のバッチが 1 件も durable にならずlanded > 0が失敗します。高速な環境では全バッチが適用されて 408 になりません。
landedの下限を 0 以上に緩めるか、COUNTを環境変数で調整可能にすると安定します。少なくとも失敗時にlandedと経過時間を出力すると、CI での原因調査が容易になります。🤖 Prompt for AI Agents

- Around line 1051-1085: Replace the fixed 200ms startup delay and
request-specific audit assertions in this concurrency test with
order-independent checks. Preserve validation that both batches are applied,
then assert that exactly one response has a normal audit object and the other
has a null audit with audit_skipped set to "overloaded", without assuming first
or second acquired the permit.

CI ran the 600-tiny-passage fixture's promote in 824ms, comfortably inside the 1s budget (824ms/600 batches vs the ~20ms/batch this machine sees), so the test's expected 408 never fired. Raise batch count to MAX_MATCH_LIMIT (1000, the request's own ceiling) and give each passage a few KB of filler so the write itself, not just per-batch bookkeeping, contributes to the margin.
The single-process, single-timeout design raced two different costs against the same budget on CI: growing per-chunk seeding cost (which needs a generous timeout) and render's own cost (which needs a tight one). Restarting to get a tight timeout for the measured call exposed a third cost neither test accounted for — a fresh process leaves `scratch`'s registry entry Cold, and `ensure_hot`'s WAL replay for this corpus (~10s, uninterruptible: it takes no `Deadline` at all) then dominates `export_context` itself, tripping AccessError::DeadlineExceeded before render is ever reached. Seed on a generous-timeout server, restart onto the tight one, then spend a throwaway warm-up call (status ignored) paying the cold-load cost before the timed promote call — matching the warm `export_context` this test's margin was actually measured against.
The restart+warm-up design still timed out on CI (nextest's 120s slow-test kill): CI runs this write pattern much slower than local, and seeding + a ~30s cold-hydrate for 500k distinct associations blew the budget even before the timed promote call ran. Reasserting ONE association from the same source many times (rather than many distinct ones) sidesteps this: the write side does an O(1) lookup regardless of accumulated count (measured constant at ~150ms per 10k-item chunk, never growing), so no restart/warm-up is needed at all — a single generous-enough timeout covers both seeding and the measured call safely. `export::render`'s own per-count loop still does the same real work N times over for that one association, and a budget well under its full-count completion time reliably interrupts it mid-loop, long before parse_stream is ever reached. Total test time drops from ~66-90s to ~33s, comfortably under both the "slow" mark (60s) and the hard kill (120s).
… tests - budget_refusal_cuts_a_multi_batch_promotion_short: drop the landed > 0 requirement (a CI machine slow enough that not even the first batch lands within the 1s budget is still a valid, if maximally early, resumable-prefix outcome) and surface elapsed time + landed count in the failure message for diagnosability. - audit_degrades_to_overloaded_when_a_concurrent_promotion_holds_the_ only_heavy_ops_permit: the 200ms head start makes the first request the LIKELY permit holder but not a guaranteed one — assert the actual invariant (exactly one of the two responses degrades to "overloaded", exactly one carries a real audit) instead of pinning which specific request wins the race.
Summary
Part of #627 (issue #537 audit series item 8), covering
src/api/promote.rs's untested refusal branches:budget_refusal— the per-batch deadline check mid-apply-loop (a resumable-prefix 408, distinct fromdeadline_exceeded's top-of-handler check).render_refusal's Timeout arm — the deadline dying insideexport::renderitself, afterexport_contextalready succeeded but before the apply loop even starts, so nothing has been written. The Conflict arm stays untested: the code's own comment says the reserved-id refusal earlier in the handler leaves the deadline as render's only reachable error, making Conflict structurally unreachable through the public API.audit_skip_reason'sdeadline_exceeded— a destination vocabulary large enough (reusing the posting-list-sweep technique from aliases/associations/coverage/vocabularyのテスト空白 #626'svocabulary.rs) thatmerge_section's lexical twin sweep alone outlasts the request budget, degrading the audit after every batch above is already durable.audit_skip_reason'soverloaded— a concurrent promotion holding the onlyTAGURU_MAX_CONCURRENT_HEAVY_OPSpermit during its own slow audit, so a second concurrent promotion'stry_acquiredegrades instead of shedding its already-applied write.Scoped out (documented per the pattern established in #626):
metadata_unreadableandno_context(both non-audit_skip_reasonarms insidelanding_audit).apply_batch(src/ingest/rejection.rs:564) unconditionally callsretract_source_unmarkedon the destination's whole passage store for every batch, regardless of whether the batch carries passage content — so a corrupted or vanished destination always fails the WRITE phase first (500, orNoContextmid-loop), beforelanding_auditis ever reached. Confirmed empirically (both with and without the promoted batch itself carrying passage content, to rule out the code's own "self-heals" comment applying here).Follows #667 (resolve.rs's semantic verdicts and provider-degrade paths), the first PR in this issue's series.
