• 🔴 (16:20) User stated the isolated workspace is /home/byk/Code/opencode-lore-responses-accumulation-review-fix and it is a jj repo. Mutable working change: rwunmtrq with description fix(responses): complete accumulation boundaries; immutable parent: tklkqxyt/ce88c614; base: 2cbf4006.
• 🔴 [enforced-workflow] (16:20) User required work to remain isolated: do not touch any server, production DB, other workspace, bookmark, or frozen parent.
• 🔴 [enforced-workflow] (16:20) User required apply_patch for edits and jj only for VCS inspection; explicitly prohibited commit, bookmark, rebase, and push operations.
• 🟡 (16:20) User asked to read AGENTS.md, quality/REVIEW.md, and package scripts before implementation.
• 🔴 [requested-tests] (16:20) User required deterministic failing-first real-wire regression tests before production edits and required running those tests against unchanged child production.
• 🟡 (16:20) Requested correctness fix 1: after Codex normalization supplies a previously omitted continuation output_index, validate the normalized local/effective shifted coordinate against the exclusive sparse ceiling before any map/array mutation or side effects.
• 🟡 (16:20) Requested regression coverage for fix 1: omitted-index continuation with principal offset at the boundary and at the first invalid coordinate, with zero extra recall/nested side effects.
• 🟡 (16:20) Requested correctness fix 2: preserve sparse private raw content coordinates, while ensuring public rebuilt terminal message content never serializes holes/nulls.
• 🟡 (16:20) Requested assertions for fix 2: principal and shifted-continuation absent/empty terminal-output frames.
• 🟡 (16:20) Requested correctness fix 3: once a continuation terminal with valid usage is accumulated, a semantic terminal reconciliation failure must account for that usage exactly once before throwing; the unsuccessful callback must receive principal+continuation usage, and there must be no successful persistence.
• 🟡 (16:20) Requested coverage for fix 3 across terminal-only, gap, and contradiction cases.
• 🟡 (16:20) Requested performance fix 4: replace the per-item scan over all raw items with indexed identity bookkeeping so a real high-cardinality stream does not require Map iterator mocking.
• 🔴 [rejected-approach] (16:20) User required removal or replacement of the mock-based high-cardinality test; timing-only oracles and Map iterator mocking are not acceptable.
• 🔴 [requested-tests] (16:20) User required a deterministic operation-bound or high-cardinality test that exercises the production path without a timing-only oracle.
• 🔴 [requested-tests] (16:20) User required each of the 4 findings to demonstrate: fail-first on parent behavior, pass after the fix, and failure under a guard-removal mutation.
• 🔴 (16:20) User required preservation of these existing semantics: authoritative response.output_text.done replacement, privacy, rollback-before-callback, cancellation/backpressure, and temporary DB setup.
• 🔴 [requested-tests] (16:20) User required running the focused full recall-aware file and gateway typecheck after implementation.
• 🟡 (16:20) User requested the final report include exact files changed, fail-first outputs, mutation evidence, tests/results, and remaining concerns.
• 🔴 (16:20) User prohibited claiming final/full validation and prohibited claiming a commit.
