Carry the bounded-retention fix from #85 (source 51723d6) onto current dev. Preserve upstream passthrough, opt-in, timestamp, and usage behavior; stop retaining after tool activity, substantive text, or replay limits. Add focused boundary regressions and document the retention contract. Co-authored-by: luvs01 <27862058+luvs01@users.noreply.github.com>

@coderabbitai full review Please review this draft's bounded-retention implementation and regression coverage, including trim-equivalent text length tracking, exact event/content boundaries, retention release after tool starts/overflow, and preservation of incomplete/error/usage behavior. The native CI approval gate is separate; this is not a review-ready or full-CI-green claim. |

The retention path is correctly scoped and bounded:
The regression matrix covers the intended boundaries:
The parameterized suite expands to 44 new cases: 22 for I also confirmed that the caller-side OpenAI Chat opt-in remains in This was a static diff review. I did not run repository code or native Bun checks. The draft status and native CI gate remain appropriate. ✅ Action performedFull review finished. |

Keep usage already reported by completed legs when the continuation factory throws or rejects; leave unknown usage absent. Add 18 lifecycle/accounting regressions covering both supported adapters, cancellation before dispatch, iteration failures and Unicode bounds. Expand guard and fixture JSDoc and update the retention contract. Node-only validation of the complete focused test file: 81 pass, 0 fail, 1 explicit Bun bridge skip. The same new tests against parent 469e7ab produce 6 failures, all for lost reported usage. Bun-native tests, repository typecheck/privacy/structure gates and exact-head hosted CI remain pending; this is not a full CI pass. Refs lidge-jun#4739

Current-head triage on f85eaa414c6a3527ab366e5cd3b77f1a44a82b61: the review threads are resolved and git diff --check is clean, but this branch is now 68 commits behind current dev and GitHub reports it conflicting. Only metadata checks ran on this draft head, so the earlier cross-platform/focused evidence is not merge evidence for the current repository tree. Please rebase onto current dev, resolve the terminal-guard split conflicts without raising the file-size baseline, and publish exact-head focused plus full hosted CI. I am withholding approval rather than duplicating the already-resolved product review.

Because this commit changes src/server/responses/terminal-guard.ts, updating only structure/transports/byte-accounting.md leaves the other documents mapped to src/server/ in structure/INDEX.md:125 untouched. Update those mapped contract documents in the same change, or correct the ownership mapping if they do not actually describe this area; repository rules explicitly require every listed document to be synchronized whenever an owned source area changes.

Useful? React with 👍 / 👎.
Maintainer integration for the 2.57.0 stabilization scope. Exact head a28a7ef has a green aggregate ci check with no failing job. The retained event set is exactly what the consumers read, overflow drops only the replay record while content, terminal reason and usage still pass through, and preserving usage from completed legs when the continuation factory throws is a real fix. The accepted cost is recorded: on overflow a thinking-heavy turn loses the guard nudge rather than losing output. Host-owned merge decision; no local suite, typecheck, build, or install was run.

Summary
Bound the terminal guard's continuation history so long reasoning streams and floods of empty deltas do not accumulate an unbounded replay record. Content still reaches the downstream consumer unchanged.

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:
All CI tests are green on my local testing. Exact-head run 35082012582 on a28a7ef passed all 26 jobs; one Windows shard needed a rerun for the shared fork-only server-auth and server-search failures described below.
I pushed my PR to the latest dev commit.
I resolved all correct Codex and CodeRabbit findings. No unresolved current review threads remain.
My PR is ready for review.
