- Around line 106-108: Update the paragraph about the buffered response
collector and Responses delegate to name `src/adapters/zed.ts` and
`src/adapters/openai-responses/passthrough.ts`. State that compaction ciphertext
is released on every exit unless its lease transfers with the yielded `done`
event, and that the Zed collector releases the lease if it refuses that event.

it.next()can yield adoneevent after the parser transfers its ciphertext lease. Theclosed || clientCancelledguard then returns before processing the event. Also,retainFinishedItemcan throw before releasingreplacedBytes. Neither path callsreleaseTranslatedEvent, so a caller-owned budget retains the ciphertext charge and later reservations can fail against its limit.Wrap the complete per-event body, including the close guard, in one
finallyblock. The block releasesnext.valuewhenever the iterator yielded an event. This covers cancellation,retainFinishedItemfailures, early returns, and normal completion.Suggested fix
iteratorStarted = true; const next = await it.next(); + try { // A cancel during this await disposes the owned budget; a late event // must never be processed or charged against it.

Addressed the outside-diff event/ciphertext cleanup finding in 79c88e9. The earlier description incorrectly treated the documentation thread as the only actionable finding; that claim is corrected. The suggested per-event finally handles serialized event leases. Raw ciphertext needed separate exact-event/exact-budget ownership so cleanup cannot release an unrelated owner's bytes. Both normal processing and the cancellation-before-first-pull bootstrap now release transferred leases. Buffered construction and Zed cleanup use the same lease; successful replacement releases ciphertext before terminal serialization to preserve near-limit admission. Eight bounded regressions failed before this fix. Final focused validation: 193 bridge/Zed/compaction tests plus 10 parser-accounting tests, all passing. The PR body records the commands and independent-review correction; current-head hosted CI remains pending. @coderabbitai review |

Superseded by the integration in #6487, with reviewed follow-up fixes in #6490 and Windows validation repairs in #6494/#6495, all merged into Zed buffered translation bounds, iterator cancellation and continuation ownership were carried. Original carry commit: Closing this PR as superseded, not claiming that its original head was merged. Thank you for the contribution. |

Commit
6485b1503a0a07b0184694741296fc51b4e0285caddresses the documentation finding from CodeRabbit's initial review by naming the owning source paths and documenting ciphertext lease transfer/refusal. Runtime code is unchanged.bun run structure:check,bun run privacy:scan,bun scripts/file-size-ratchet.ts, and whitespace validation pass. The review thread is resolved; CodeRabbit also marked it addressed. CI for that historical documentation head completed successfully. The documentation thread is resolved. A later outside-diff finding identifies a separate SSE event/ciphertext lease cleanup gap on cancellation or processing failure. Source inspection and eight failing bounded regressions confirmed it at6485b150. That head's earlier all-findings-resolved/readiness claims were withdrawn; the code follow-up and new-head evidence are recorded below. Prior-head results above remain historical evidence. That documentation-head comparison was within the repository's ten-commit tolerance.Event-lease cleanup follow-up
Commit
79c88e9c8d8c370f562f64173eb28874329f00e3addresses the outside-diff finding. The SSE bridge releases source-event leases in a per-eventfinally, including late cancellation, processing failure and its pre-first-pull cancellation bootstrap. Raw ciphertext has a separate exact-event/exact-budget lease; uncharged fields and repeated releases cannot subtract another owner's bytes. Successful replacement releases ciphertext before terminal serialization, preserving the previous near-limit admission behavior. Buffered response building and Zed failure cleanup consume the same ownership contract.bun test tests/responses/compaction-event-ownership.test.ts tests/providers/zed-retained-budget.test.ts tests/providers/zed-hosted-provider.test.ts tests/adapters/bridge.test.ts tests/responses/compaction-progress.test.ts tests/responses/responses-compaction.test.ts: 193 pass / 0 fail, 840 assertions.bun test tests/responses/openai-responses-passthrough.test.ts -t 'Responses request and compaction byte accounting': 10 pass / 0 fail, 46 assertions.bun run typecheck,bun run structure:check,bun run privacy:scan, and whitespace checks: passed.
