📝 WalkthroughWalkthroughThe devlog consolidates findings for three bug issues. It records Windows CI diagnoses, crash-retry and shell-command changes, shadow-helper attribution, provider-stream investigation status, terminal-event retention handling, and verification results. ChangesBug backlog consolidation
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🟡 Moderate · up to The devlog records the terminal-stream fix as complete, but retained per-delta events can still grow without a bound, leaving the documented outcome incomplete and potentially masking runtime growth; this should be resolved or explicitly accepted before merging.

| **Second finding, fixed in the same PR.** Making the adapter emit one heartbeat per delta | ||
| exposed that `guardTerminalEventStream` retained every nonterminal event in `seen`, which feeds | ||
| both the continuation analysis and the rebuilt request. A large argument payload could grow it | ||
| without bound wherever `terminalContinuationGuard` is on. The empty-completion guard already | ||
| passes heartbeats through unretained; the terminal guard now matches it. |

Bound retained events in guardTerminalEventStream.
src/types/request.ts:269-284 defines heartbeat and tool_call_delta events. src/server/responses/terminal-guard.ts:225 retains both in seen, and tool_call_delta.arguments can be large. buildContinuationRequest receives seen at line 205, but its assistant-message builder ignores these events. A test that checks only the rebuilt request will pass while seen still grows.
Filter non-semantic events before retention, or maintain a bounded semantic summary. Add a regression test for the retained state.

Summary
Records the three-issue round — #2152, #2157, #2156 — including the one verdict that is not a fix.
Two shipped (#2178, #2179). The third is honestly blocked, and the record says why rather than shipping something adjacent and calling it done.
Three things worth reading here:
Two of #2152's own premises were wrong, and the fix follows the evidence instead. Group 1 was not "the case budget is too small" —
A-reducedfailed at 79,978 ms against a 150 s ceiling, so the outer budget was never the constraint; the abort came from an unscaled 10 sAbortSignalfiring from inside. Group 2 was not "an unprivileged Windows user cannot create symlinks" — the runner can, and the cases then failed on Unix mode semantics a Windows directory cannot satisfy, which is what makes the platform skip correct rather than masking.The Windows crash retry keyed on the wrong signature, and this repository had already written down why.
050_windows_ci_flake_rca.md:172says not to anchor onpanic(thread, because Bun emits both that andpanic(main thread)for the same failure. Probed: the numbered form matches, the main-thread form does not. The retry would have failed the shard on roughly half the crashes it exists to absorb, while looking correct. Three copies of that list had drifted; the contract test now pins the sync itself, not the text.#2180 did not fix #2156, and no longer claims to. A stall abort emits
response.incomplete/upstream_stall_timeoutfrom a path the bridge has already closed; the reporter's error comes from the adapter reading EOF with tool calls pending. Different path, different frame. The heartbeat fixes a real false-stall hazard on its own, and exposed a second defect — the terminal guard retaining per-delta heartbeats — which is fixed with it. #2156 staysneeds-infowith a specific question asked, because the adapter is reporting truthfully and what cannot be told from here is why that stream ended for ocx and not for Pi.Verification
