     "note": "packages/opencode/src/session/stream-stalled.ts, packages/opencode/src/session/tool-activity.ts, and packages/opencode/test/session/tool-activity.test.ts were deleted by a90c49880b — confirmed intentional, not a merge regression: a full, reasoned commit message explains that the stream-inactivity watchdog these files implemented only ever fired on false positives (host-paced hybrid loads, foreground subagents, compaction's single big call, cold-load chunks — each already special-cased before this commit finished the trend) and never once caught a genuinely wedged socket, while its false positives were abandoning working turns fleet-wide. Same commit also removed the fork patches this manifest tracked in llm.ts (marker @/local/skein-loading — the SkeinLoading cold-load liveness tick that fed only this watchdog), message-v2.ts (marker StreamStalledError — the error-mapping case for the watchdog's failure type; message-v2.ts no longer diverges from upstream at all and was fully removed from `patched`), and tools.ts (marker \"fork: the stream watchdog must not count\" — the per-tool-call liveness ticks). llm.ts and tools.ts each still diverge from upstream for unrelated, still-live fork reasons and were re-registered in `patched` with fresh markers (see those entries) rather than dropped — only the watchdog-specific tracking was retired.",
