Refs #3772 (the rotation half — EPIPE shutdown-noise suppression
remains a separate follow-up).
`src/shared/logger.ts` appends every entry to `os.tmpdir()/oh-my-opencode.log`
via `fs.appendFileSync` with no size cap. On long-running or busy projects
the file grows into the multi-GB range — a real-world reproduction on one
machine showed a 4.5 GB `oh-my-opencode.log.1` accumulated from per-shutdown
noise across many sessions. Eats `%TEMP%` on Windows and `/tmp` on Unix.
Add size-based rotation inside the existing batched `flush()` path:
oh-my-opencode.log → oh-my-opencode.log.1
oh-my-opencode.log.1 → oh-my-opencode.log.2 (oldest dropped)
Cap is 50 MB per file; worst-case on-disk footprint is therefore ~150 MB.
The check runs only inside `flush()`, so the cost is amortized over
`BUFFER_SIZE_LIMIT` (50 entries) or the 500 ms flush timer. All filesystem
ops stay wrapped in try/catch — logging must never throw — and a failed
rotation leaves existing on-disk state intact rather than crashing the
agent. Pattern mirrors `src/openclaw/reply-listener-log.ts`, but with two
backup slots instead of one to keep a usable history window for debugging.
No config knobs in this iteration. The issue proposes `logs.max_size_mb`
/ `logs.max_files`, but the defaults are reasonable and adding schema is
more surface area than the bug warrants. Easy to promote later (the
existing test seams already let callers override the cap).
Tests:
- `src/shared/logger.test.ts` (new): under-threshold no-rotate, over-
threshold rotates to `.1`, repeated rotation evicts oldest, rotation-
failure-doesn't-throw, default path lives under `os.tmpdir()`. Uses a
`mock.module(...)` substring marker so `script/run-ci-tests.ts` routes
the file to its own bun process — the logger module's singleton state
otherwise gets contaminated by sibling tests that mock `./shared`.
Out of scope: suppressing specific shutdown-noise messages (EPIPE,
`unhandledRejection received during shutdown cleanup`). The rotation
cap bounds the disk impact regardless of which noise pattern is
generating volume; per-message suppression can stand on its own
merits in a follow-up.
Source code change:
- src/shared/model-requirements.ts: prepend claude-sonnet-4-6 to metis fallback
chain so Sonnet becomes the default. Opus 4.7 max remains as the immediate
fallback for callers who want extra reasoning.
- src/shared/model-requirements.test.ts: update assertion to expect Sonnet
primary + Opus secondary.
AGENTS.md accuracy fixes (verified against source):
- Agent modes: Sisyphus/Hephaestus are 'primary' (not 'all'); Sisyphus-Junior
is 'subagent' (not 'all'). Confirmed via 'const MODE: AgentMode = ...' in
each agent file. Also clarified Prometheus has no agentSources factory and
is built via buildPrometheusAgentConfig.
- Sisyphus fallback chain: corrected order to kimi-k2.6 → k2p5 → kimi-k2.5
→ gpt-5.5 medium → glm-5 → big-pickle (was missing kimi-k2.5).
- Librarian/Explore: added missing minimax-m2.7 step between -highspeed and
claude-haiku-4-5.
- Metis chain: removed fictitious gemini-3.1-pro entry.
- Sisyphus-Junior chain: spelled out the actual fallback (was 'user-configurable').
- Temperatures: Sisyphus/Hephaestus do not set explicit temperature (model
default); Sisyphus-Junior is 0.1 via SISYPHUS_JUNIOR_DEFAULTS.
- Quick category default: gpt-5.4-mini (not gpt-5.4-mini-fast).
Team-mode corrections:
- Eligibility registry has 3 verdicts: eligible (sisyphus, atlas, sisyphus-junior),
conditional (hephaestus — needs D-36 teammate permission), hard-reject
(oracle, librarian, explore, multimodal-looker, metis, momus, prometheus).
- Schema has 11 fields, not 4: added max_messages_per_run, max_wall_clock_minutes,
max_member_turns, base_dir, message_payload_max_bytes, recipient_unread_max_bytes,
mailbox_poll_interval_ms.
- Hooks: 'team-session-events' is 4 sub-handlers in src/plugin/event.ts
(team-idle-wake-hint, team-lead-orphan-handler, team-member-error-handler,
team-member-status-handler), not a single Continuation-tier hook.
- Tier counts now show base + team-mode: ToolGuard 14/15, Transform 5/7.
- Total: 52 base hooks, 59 with team-mode.
