• 🟡 (15:57) Warning-only accumulation review task ses_f55798147ffer6R77zG3gjpmTj returned no verdict because Lore recall failed. Assistant retired it as a duplicate because a separate exact-head accumulation correctness reviewer remained active.
• 🟡 (15:57) Assistant moved to the Codex reasoning lane, where the remaining reviewed defects were terminal-only summary injection and bounded high-cardinality validation.
• 🟡 (15:57) Work tracker changed to: 1. “Await projection exhaustive validation and independent reviews” — pending, high priority; 2. “Await accumulation exhaustive validation and independent reviews” — pending, high priority; 3. “Resolve any projection or accumulation review findings” — pending, high priority; 4. “Repair Codex terminal-summary and complexity findings with failing-first tests” — in progress, high priority; 5. “Update projection PR only after both reviews pass” — pending, high priority; 6. “Resume private-reference and recovery repair lanes” — pending, high priority.
• 🟡 (15:58) Codex workspace was initially clean at empty working copy rtwyxzrr / e1b1a27d09998cae0adae631b8569dd3cb2001e9, parent uyznyvwt / 4db889eb8b26cc6feef8621e6f93968575ba9c02 (fix/codex-sparse-reasoning, description fix(responses): validate Codex reasoning summaries), based on earlier uwoyklqrsuuxkkolxrzwpmprktwvyoky / 1e3657a08fd82c6f15b5c0147dff4aae197f8dca (fix(gateway): recover principal Responses transport failures (#1776)). The unrelated fix/responses-private-references bookmark remained conflicted.
• 🟡 (15:58) Assistant decided to repair the Codex candidate additively on its earlier 1e3657a0 base, prove the defect there, then rebase the focused stack onto current main and repeat validation.
• 🟡 (15:58) A named empty Codex child was created: working copy rtwyxzrr / 3ac75ca04d0dde143165dbcbdb2df7b5d070865b, description fix(responses): reject untracked Codex reasoning, with parent uyznyvwt / 4db889eb8b26cc6feef8621e6f93968575ba9c02.
• 🟡 (15:59) Search of packages/gateway/test/openai-responses-recall-aware-stream.test.ts found 32 Codex reasoning-summary-related matches, including response.reasoning_summary_text.done, response.reasoning_summary_part.done, forged response.reasoning_summary_private.done, added-only summary preservation, sparse terminal-summary reconstruction, oversized summary rejection, terminal omission handling, and invalid untracked and gapped cases.
• 🟡 (15:59) Assistant determined the existing Codex branch already bounded added/done summaries and validated lifecycle events. The uncovered wire sequence was narrower: both added and done events omit summary, then the terminal introduces a nonempty summary array.
• 🟡 (15:59) Assistant planned principal and continuation fail-first regressions for that exact terminal-only Codex summary sequence, each placing valid recall calls after malformed reasoning to prove zero recall side effects.
• 🔴 (16:01) Projection correctness review stated terminal-resolved ordinary sparse tools never enter the visible projection.
• 🔴 (16:01) Projection correctness review stated terminal reconciliation at packages/gateway/src/pipeline.ts:10632-10670 removes a resolved ordinary tool from unresolvedToolIndices but never calls syncVisibleOutputIndex(), leaving stale projection state for the stability check at :10678.
• 🔴 (16:01) Projection review’s counterexample used source index 1 as visible text already emitted at public index 0, source index 0 as a sparse function call with blank identity, and terminal output resolving source 0 as an ordinary tool. Deferred delivery at packages/gateway/src/pipeline.ts:10706-10715 reaches enqueueProjectedPrincipal(), which throws because the source index is absent from visibleOutputIndices at :10277-10279.
• 🔴 (16:01) Projection review stated the terminal-resolved-tool failure can leave projectionInvalid false, causing the failure terminal to use buildOutputItems() at packages/gateway/src/pipeline.ts:11985-11987 and expose [tool-0, message-1] even though message 1 was already streamed at public index 0.
• 🔴 (16:01) Projection review required higher- and lower-index terminal-resolution regressions: higher indices must succeed; lower indices must fail with empty public output before exposing the newly resolved item.
• 🔴 (16:01) Projection correctness review stated semantic-event prefix checks allow indexed extension data to bypass redaction. isSemanticResponsesEvent() uses broad prefixes at packages/gateway/src/pipeline.ts:8060-8074; for example, response.output_text.private_extension passes. Lifecycle logic at :8618-8663 treats any response.output_text.* event as indexed text activity without rejecting unknown suffixes; the original payload is queued at :11729-11749, and remapping preserves arbitrary fields through { ...parsed } at :10023-10025.
• 🔴 (16:01) Projection review stated provider-private data can reach the client through an indexed prefix-collision event after recall interception.
• 🔴 (16:01) Projection review identified a second redaction-ordering hole: unknown principal frames received before a late recall are immediately forwarded at packages/gateway/src/pipeline.ts:10364-10371 and :10378-10390, and a later recall cannot retract them.
• 🔴 (16:01) Projection review stated existing tests covered diagnostic and response.custom only after recall at packages/gateway/test/openai-responses-recall-aware-stream.test.ts:8223-8264 and :8372-8453, but did not cover prefix-collision event names, indexed extensions, extension fields on otherwise valid semantic frames, or extensions emitted before a late recall.
• 🔴 (16:01) Projection review directed use of an exact semantic-event allowlist and buffering of unreviewed principal frames until the terminal proves no recall occurred.
• 🔴 (16:01) Projection correctness review stated continuation codex.rate_limits metadata is accumulated into contState at packages/gateway/src/pipeline.ts:11049-11052 and then discarded because mergeContinuation() at :11389-11448 copies only items, raw items, and usage.
• 🔴 (16:01) Projection review stated continuation quota metadata never reaches the authoritative response consumed by onComplete, because finalization uses principal state at packages/gateway/src/pipeline.ts:11640.
• 🔴 (16:01) Projection review stated this lost quota metadata contradicts the explicit “always accumulate” comment and the established buffered behavior, which merges ordered rate-limit updates at packages/gateway/src/pipeline.ts:18714-18722.
• 🔴 (16:01) Projection review required codex.rate_limits tests for principal, continuation, chained continuation, retry, and rollback cases. It also required restoring codexRateLimits from transactionBaseline, which restoreTransactionBaseline() currently omits at packages/gateway/src/pipeline.ts:8016-8027.
• 🔴 (16:01) Projection review raised an adversarial complexity concern: syncVisibleOutputIndex() uses binary search, but each middle insertion calls splice() and rewrites every later map entry at packages/gateway/src/pipeline.ts:10211-10240; a hidden recall followed by visible items in descending source-index order can therefore force quadratic work before forwarding.
• 🔴 (16:01) Projection review stated the existing complexity test uses 64 ascending indices and counts only numeric sort() calls at packages/gateway/test/openai-responses-recall-aware-stream.test.ts:8310-8370; it required descending deferred input and an operation-count or time-independent work bound.
• 🔴 (16:01) Projection review judged fail-first proof incomplete. Existing guard-removal assertions covered: lower terminal recall preventing callback execution at test line 2760; index overflow preventing recall and follow-up at 4936; late lower output clearing the public failure projection at 5910; and lower late recall failing before execution at 5958. However, no base-run evidence was supplied, strict read-only review prevented running the base, and the three must-fix defects lacked regressions.
• 🟡 (16:01) Projection review integrity checks passed: stable change zlsmzkntqzzxsqvyxzzpxltmrsprymww resolved to a3fa555bdcabb376aa33278bdb76007269f1940a; base resolved to 2cbf40060c67df229731cf1b9e34d5bf22ec2145; scope was exactly packages/gateway/src/pipeline.ts and packages/gateway/test/openai-responses-recall-aware-stream.test.ts; diff hash remained a7e914bd8ffb704f8fba2798f9de95fd4668b7212a485304c1cf7c056c278a40; clean empty child was 884f9b007c89e71800dbebc00af2e22f0454e592; the candidate range had no conflicts; and the unrelated fix/responses-private-references bookmark remained conflicted.
• 🟡 (16:01) Projection focused validation passed 223/223 tests in 12.15s using --printConsoleTrace.
• 🟡 (16:01) Projection review passed tested normal sparse projection behavior: numeric ordering, continuation shifting, synthetic-anchor coordinates, and dense terminal reconstruction were coherent for tested monotonic and deferred cases at packages/gateway/src/pipeline.ts:9893-10029, :11005-11012, and :11638-11675.
• 🟡 (16:01) Projection review passed contiguous sequence-number assignment at packages/gateway/src/pipeline.ts:9608-9635; terminal sanitization that no longer spreads arbitrary provider fields and rejects invalid continuation created_at before reconstruction at :9230-9239 and :9862-9889; retry reset of all projection registries at :11834-11848; and backpressure, cancellation, and exact-once completion behavior at :9638-9649, :10049-10088, and :12027-12043.
• 🟡 (16:01) Projection review verdict was DO-NOT-MERGE because terminal-resolved-tool failure, indexed-extension redaction bypass, and lost continuation quota state violated correctness and privacy invariants.
• 🟡 (16:01) Assistant accepted the three projection defects and adversarial complexity gap as real, kept immutable candidate a3fa555b blocked, paused the Codex lane, and decided to make fixes only in an additive projection child.
• 🟡 (16:01) Assistant’s fail-first projection repair order was: 1. terminal-resolved tools; 2. exact semantic-event filtering plus pre-recall extension buffering; 3. continuation quota state plus retry rollback; 4. descending-order projection work.
• 🟡 (16:02) Work tracker changed to: 1. “Fix projection correctness review findings with failing-first tests” — in progress, high priority; 2. “Revalidate and independently review corrected projection candidate” — pending, high priority; 3. “Await accumulation exhaustive validation and independent reviews” — pending, high priority; 4. “Repair Codex terminal-summary and complexity findings with failing-first tests” — pending, high priority; 5. “Update projection PR only after both reviews pass” — pending, high priority; 6. “Resume private-reference and recovery repair lanes” — pending, high priority.
• 🟡 (16:03) Created clean empty projection repair child lnvrxqoq / 5eb9744aa93dea943d8d037f17c83b232ff073a2, description fix(responses): complete hidden-output state, on immutable parent zlsmzknt / a3fa555bdcabb376aa33278bdb76007269f1940a (fix/responses-hidden-output, description fix(responses): harden hidden-output projection). Base remained pxrvwsvv / 2cbf40060c67df229731cf1b9e34d5bf22ec2145; fix/responses-private-references remained conflicted.
