MessageAbortedError/worker shutdown could race with scheduled removeTask, leaving background_output's manager.getTask returning 'Task not found' even though the task had completed cleanly.
Fix: add completedTaskArchive (max 500, FIFO eviction). On removeTask, archive non-running/pending tasks with sessionId. getTask falls back to archive on active-map miss. addTask clears stale archive entries on re-registration.
Fixes#3895
Replaces direct fileHandle.sync() calls in acquireLock and atomicWrite
with tolerantFsync. Users on iCloud Drive / OneDrive / Desktop sync
folders were hitting 'EPERM: operation not permitted, fsync' during
team_create, which propagated up and aborted the entire team_create
flow even though the actual write+rename had succeeded.
Reported on Discord (omo 4.0.0, opencode desktop 1.14.41, project on
synced Desktop). atomicity is preserved by the temp-file rename; only
the durability hint is now best-effort on filesystems that disallow
fsync.
The previous commit (2dfa6336f) used 'git add -A' which swept up files that
prior commits had intentionally deleted but were still present untracked in
the local workspace. This commit re-deletes them to match the upstream intent.
Files removed (each was previously deleted in the cited commit):
- drafts/gpt-5-5/{README,deep,hephaestus,oracle,sisyphus-junior,sisyphus}.md
(deleted in 40ded422c chore(drafts): remove stale gpt-5.5 prompt drafts)
- src/plugin-dispose.{ts,test.ts}
(deleted in e2f5c0d36 refactor(plugin): remove orphaned createPluginDispose)
- src/features/tmux-subagent/{cleanup,session-created-handler,session-deleted-handler}.ts
(deleted in 7a7926f22 chore(tmux-subagent): remove dead event-handler modules)
- src/tools/delegate-task/{model-string-parser,resolve-call-id,resolve-call-id.test}.ts
(model-string-parser deleted in db056346d; resolve-call-id was scratch)
- src/__debug-test.test.ts (debug scratch never intended for git)
Typecheck + model-requirements tests still pass. The legitimate metis +
AGENTS.md edits from the previous commit remain on dev.
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.
Doc cascade for the Metis change:
- docs/guide/orchestration.md, agent-model-matching.md, installation.md
- docs/reference/configuration.md, features.md
Agent names like \hephaestus\ cause 'Agent not found' errors because
sanitizeSubagentType() was only called in subagent-resolver.ts but not
in the direct manager.launch() path or background-executor.ts.
- manager.ts: strip leading/trailing backslash/quote chars from input.agent
before validation so \hephaestus\ → hephaestus
- background-executor.ts: call sanitizeSubagentType(args.subagent_type)
instead of passing raw value to manager.launch()
- agent-display-names.ts: reuse sanitizeSubagentType in stripAgentListSortPrefix
- Add unit tests for all three fix points
Fixes: sessions dying with 'Agent not found: \hephaestus\'
Replace in-window pane splitting with two purpose-built windows
(focus: main-vertical, grid: tiled) created off the target session,
so leader pane is never disturbed and layouts no longer collapse
under teammate count.

Drop the per-pane select-pane title shuffle and the cyan border styling that leaked to window scope, then switch from main-vertical to tiled when there are 4 or more teammates so each pane keeps a usable height for the opencode TUI.

Bring the team member addendum and the team-mode skill in line with the
Claude Code experimental Agent Teams reference (../free-code) on the
behavioral framing the LLM needs, while keeping every omo-specific
constraint (TeamRunId param, lead-only tool blocklist, eligibility
registry, sisyphus-junior routing) intact.
Member addendum (src/features/team-mode/member-guidance.ts) — adopt
free-code teammatePromptAddendum.ts wisdom that was missing:
- "User interacts primarily with the team lead" — members no longer try
to address the user directly; they coordinate via task system + DMs.
- Stronger emphasis that plain assistant text is invisible to the team;
team_send_message is mandatory, not optional.
- Broadcast (`to: "*"`) called out explicitly with "sparingly" guidance
and the lead-only constraint.
- "Idle is normal" section: idle ≠ done, idle teammates can still
receive messages, the lead must not treat idle as an error.
- "Communication rules" section forbidding structured JSON status
messages and forbidding terminal tools as a peer-inspection backdoor;
always reference teammates by NAME, not session ID.
- Auto-delivery framing: messages arrive as new turns, no manual inbox
polling, no need to quote a teammate's message back to the lead.
Team-mode skill (src/features/builtin-skills/skills/team-mode.ts) —
adopt free-code TeamCreateTool/prompt.ts sections that were missing:
- Task ownership: any agent can set/change `owner` via team_task_update.
- Automatic message delivery: <peer_message ...> envelope flow.
- Teammate idle state: idle is the expected post-turn state; peer DM
summaries surface in the lead's idle notification.
- Discovering team members: team_status + ~/.omo/teams/ config; refer by
name, never raw session IDs.
- Task list coordination: claim by ID order (lowest first), check after
every completion, escalate blocking deadlocks to the lead.
- Communication rules: same anti-patterns as the member addendum, scoped
for the lead's awareness (no JSON status, no terminal peer-inspection,
no delegate-task from inside members).
Test (create.test.ts) updated to track the renamed section header
("Lead-only tools you must NOT call") and to lock the new free-code
parity assertions ("user interacts primarily with the team lead",
"Idle is normal", "structured JSON status messages").
All other contract tests (team-mode skill keyword/section tests,
member parser, runtime tests) untouched and still passing.

The shared resolveCategoryExecution path treats `agents.sisyphus-junior.model`
(plugin config) as a higher-precedence override than the category default. That
ranking is correct for plain `task(category=...)` delegations - it lets users
pin sisyphus-junior to their preferred general model - but in team-mode it
collapses every kind:"category" member onto the same model.
Hyperplan was the visible victim: skeptic/validator/researcher/architect/creative
are routed through sisyphus-junior with five distinct categories
(unspecified-low / unspecified-high / deep / ultrabrain / artistry). With any
sisyphus-junior model configured, all five resolved to that single override
model instead of their category defaults, defeating the multi-model adversarial
debate.
Strip the override at the team-mode boundary in resolveMember rather than
changing resolveCategoryExecution itself, so:
- delegate-task callers keep the existing override semantics (3 regression
tests at tools.test.ts:2832, 2958, 3020 stay green)
- per-category user overrides (`categories[X].model`) and explicit fallback
chains continue to apply
- only the `kind:"category"` team-mode path opts out of the global override
Lock the contract with a regression test in resolve-member.test.ts.

Update both injection paths to reflect the 7-phase workflow with the
mandatory plan agent handoff in step 7. The keyword detector now lists
all 8 enumerated steps including the explicit "do not write the plan
yourself" guidance, and the /hyperplan command template references the
7-phase workflow count.
