• 🟡 (15:18) Ten repeated Vitest runs in /home/byk/Code/opencode-lore-responses-projection-security each passed exactly 17 tests and skipped 205 of 222 in 1 test file. Runs: 1. start 15:16:17, duration 5.76s (transform 3.08s, setup 525ms, import 4.79s, tests 213ms, environment 0ms); 2. start 15:16:25, duration 6.92s (transform 3.97s, setup 833ms, import 5.49s, tests 241ms, environment 0ms); 3. start 15:16:33, duration 6.31s (transform 3.47s, setup 576ms, import 5.23s, tests 265ms, environment 0ms); 4. start 15:16:41, duration 7.47s (transform 4.26s, setup 630ms, import 6.26s, tests 274ms, environment 0ms); 5. start 15:16:51, duration 6.29s (transform 3.37s, setup 594ms, import 5.22s, tests 259ms, environment 0ms); 6. start 15:16:59, duration 6.56s (transform 3.65s, setup 697ms, import 5.34s, tests 247ms, environment 0ms); 7. start 15:17:07, duration 7.77s (transform 4.45s, setup 509ms, import 6.71s, tests 325ms, environment 0ms); 8. start 15:17:17, duration 8.43s (transform 4.47s, setup 650ms, import 7.27s, tests 263ms, environment 0ms); 9. start 15:17:28, duration 10.12s (transform 5.87s, setup 483ms, import 8.20s, tests 1.13s, environment 0ms); 10. start 15:17:42, duration 7.00s (transform 3.68s, setup 724ms, import 5.80s, tests 219ms, environment 0ms).
• 🟡 (15:19) @loreai/gateway@0.40.0 bundled successfully from /home/byk/Code/opencode-lore-responses-projection-security/packages/gateway via tsx script/bundle.ts. Outputs: dist/index.cjs 16.7mb and dist/index.cjs.map 43.7mb in 2785ms; dist/index.bun.js 16.2mb in 1700ms; dist/embedding-worker.cjs 565.1kb in 380ms; dist/embedding-worker.js 564.9kb in 318ms; dist/vector-worker.cjs 11.1kb in 10ms; dist/vector-worker.js 10.3kb in 10ms. Bundle also included dist/ort-wasm-simd-threaded.{mjs,wasm}, dist/bin.cjs, and dist/index.d.cts. Debug ID 4dd89559-9b29-4861-9369-0f3851fda2c8 was injected; no SENTRY_AUTH_TOKEN was present, so sourcemap upload was skipped.
• 🟡 (15:19) Inspection of packages/gateway/src/pipeline.ts showed buildOutputItemsWithIndices() skips hiddenIndices, visibleOutputIndexMap() maps internal indices to contiguous visible indices, and remapVisibleOutputIndices() rewrites SSE output_index values. remapVisibleOutputIndices() throws Error("hidden Responses output item reached the client") if an event references an index absent from the visible map.
• 🟡 (15:20) Projection-security investigation identified that the local ledger removed per-event sorting, but terminal-discovered recalls entered through a separate callback. Hypothesis: a lower-index terminal-discovered recall could reserve the same public synthetic-anchor slot and therefore must fail before onRecall, matching streamed-recall admission behavior.
• 🟡 (15:21) Existing test allows a terminal-discovered recall that preserves sparse visible output positions in packages/gateway/test/openai-responses-recall-aware-stream.test.ts uses visible text at output_index: 7 and a recall function call at output_index: 9; it expects exactly 1 recall, preserves "sparse visible text" and "terminal continuation answer", hides query/result/call identifiers, emits exactly 1 response.completed, emits no response.failed, and verifies visible output indices match terminal output.
• 🟡 (15:21) Investigation isolated an untested seam: a sparse function call can remain unresolved until response.completed identifies it as recall. A lower-index version must fail before onRecall, because inserting its synthetic anchor would reindex an already-emitted visible item despite all streamed recall frames remaining hidden.
• 🟡 (15:22) Added regression test fails closed when a terminal-discovered recall would reindex visible output to packages/gateway/test/openai-responses-recall-aware-stream.test.ts.
• 🟡 (15:23) Failing-first run of fails closed when a terminal-discovered recall would reindex visible output confirmed the missing guard: recallCalls was 1 instead of expected 0 at line 2823. Vitest result was 1 failed and 222 skipped of 223 tests in 1 file; duration 10.54s (transform 5.69s, setup 982ms, import 9.00s, tests 100ms, environment 0ms). Logs classified the subsequent failures as follow_up_setup, showing onRecall ran before the projection contradiction was rejected.
• 🟡 (15:23) Updated packages/gateway/src/pipeline.ts to share the lower-index synthetic-anchor admission check between streamed and terminal-discovered recalls, ensuring a projection contradiction is rejected before onRecall.
• 🟡 (15:24) Fixed-tree focused validation passed exactly 2 tests and skipped 221 of 223 in packages/gateway/test/openai-responses-recall-aware-stream.test.ts; duration 7.48s (transform 4.44s, setup 752ms, import 6.36s, tests 96ms, environment 0ms).
• 🟡 (15:24) Mutation proof removed/disabled the terminal-path guard in packages/gateway/src/pipeline.ts; the regression failed again because recallCalls was 1 instead of 0 at line 2823. Result: 1 failed and 222 skipped of 223 tests; duration 7.46s (transform 4.48s, setup 796ms, import 6.19s, tests 223ms, environment 0ms). This demonstrated that the new terminal-discovered admission check is necessary.
• 🟡 (15:26) User instructed the assistant to continue.
• 🟡 (15:26) Assistant reported complete fail-first, fixed-tree, and guard-removal evidence for the terminal-discovered guard. A separate provider-security review returned substantive MERGE approval on its immutable candidate; that lane remained isolated from the projection workspace.
• 🟡 (15:26) Full packages/gateway/test/openai-responses-recall-aware-stream.test.ts projection suite passed exactly 223/223 tests in 1 file after restoring the terminal-path fix; start 15:26:24, duration 6.86s (transform 3.27s, setup 614ms, import 5.01s, tests 1.05s, environment 0ms).
• 🟡 (15:27) Work plan status, in order: 1. Audit and finish hidden-output security corrections with failing-first and mutation proof — completed, high priority; 2. Run affected, static, property, bundle, and exhaustive validation on exact candidate — in progress, high priority; 3. Commit, freeze, and independently review the security correction — pending, high priority; 4. Rebase/update projection PR only after both reviews pass — pending, high priority; 5. Resume remaining focused provider, Codex, accumulation, reference, and recovery lanes — pending, high priority.
