840c612be8 fix(background-agent): queue notifications for idle parent sessions
When a background task completes and the parent session is waiting for
user input, promptAsync() fails with an aborted error. Previously the
notification was silently dropped — lost forever.

Fix: queue the notification text in-memory on the BackgroundManager
when promptAsync fails with an aborted/idle error. On the user's next
message to that session, the queued notifications are injected into the
chat context before the agent sees the message.

- BackgroundManager: add pendingNotifications map + queuePendingNotification()
  and injectPendingNotificationsIntoChatMessage() methods
- background-notification hook: add chat.message handler that calls injection
- chat-message.ts: wire backgroundNotificationHook.chat.message into the
  message processing chain
- Add tests covering queue-on-abort and next-message delivery

03f7643ee1 fix(background-agent): respect agent tool restrictions in background task launch
Reorder tool permission spread so getAgentToolRestrictions() comes
last, allowing agent-specific restrictions to override defaults.
Fixes all 3 sites: task-starter.ts (startTask), manager.ts (startTask
and resume paths).

Previously, defaults like call_omo_agent:true would stomp agent
restrictions (e.g., explore's call_omo_agent:false) due to JS
spread semantics.

33d290b346 fix: add toast cleanup to all BackgroundManager task removal paths
TaskToastManager entries were never removed when tasks completed via
error, session deletion, stale pruning, or cancelled with
skipNotification. Ghost entries accumulated indefinitely, causing the
'Queued (N)' count in toast messages to grow without bound.

Added toastManager.removeTask() calls to all 4 missing cleanup paths:
- session.error handler
- session.deleted handler
- cancelTask with skipNotification
- pruneStaleTasksAndNotifications

8a5f61724d fix(background-agent): handle message.part.delta for heartbeat (OpenCode >=1.2.0)
OpenCode 1.2.0+ changed reasoning-delta and text-delta to emit
'message.part.delta' instead of 'message.part.updated'. Without
handling this event, lastUpdate was only refreshed at reasoning-start
and reasoning-end, leaving a gap where extended thinking (>3min)
could trigger stale timeout.

Accept both event types as heartbeat sources for forward compatibility.

a0c9381672 fix: prevent stale timeout from killing actively running background tasks
The stale detection was checking lastUpdate timestamps BEFORE
consulting session.status(), causing tasks to be unfairly killed
after 3 minutes even when the session was actively running
(e.g., during long tool executions or extended thinking).

Changes:
- Reorder pollRunningTasks to fetch session.status() before stale check
- Skip stale-kill entirely when session status is 'running'
- Port no-lastUpdate handling from task-poller.ts into manager.ts
  (previously manager silently skipped tasks without lastUpdate)
- Add sessionStatuses parameter to checkAndInterruptStaleTasks
- Add 7 new test cases covering session-status-aware stale detection

4ab93c0cf7 fix: refresh lastUpdate on all message.part.updated events, not just tool events
Reasoning/thinking models (Oracle, Claude Opus) were being killed by the
stale timeout because lastUpdate was only refreshed on tool-type events.
During extended thinking, no tool events fire, so after 3 minutes the
task was incorrectly marked as stale and aborted.

Move progress initialization and lastUpdate refresh before the tool-type
conditional so any message.part.updated event (text, thinking, tool)
keeps the task alive.

b0c570e054 fix(subagent): remove permission.question=deny override that caused zombie sessions
Child session creation was injecting permission: { question: 'deny' } which
conflicted with OpenCode's child session permission handling, causing subagent
sessions to hang with 0 messages after creation (zombie state).

Remove the permission override from all session creators (BackgroundManager,
sync-session-creator, call-omo-agent) and rely on prompt-level tool restrictions
(tools.question=false) to maintain the intended policy.

When the main session is aborted while background tasks are running,

- Separate synthetic messages were ignored by model (treated as previous turn)
- Prepending to clone ensures: UI shows original, model receives prepended content
- Update tests to reflect new behavior

* refactor(oracle): change default model from GPT-5.2 to Claude Opus 4.5

* feat(oracle): change default model to claude-opus-4-5

* fix(sisyphus-orchestrator): check boulder session_ids before filtering sessions

session_ids because the session filter ran BEFORE reading boulder state.

Fix: Read boulder state first, then include boulder sessions in the

- Fix existing tests to include skills parameter

* fix: prevent session model change when sending notifications

- background-agent: use only parentModel, remove prevMessage fallback
- todo-continuation: don't pass model to preserve session's lastModel
- Remove unused imports (findNearestMessageWithFields, fs, path)

Root cause: session.prompt with model param changes session's lastModel

* fix(sisyphus-orchestrator): register handler in event loop for boulder continuation

* fix(sisyphus_task): use promptAsync for sync mode to preserve main session

- session.prompt() changes the active session, causing UI model switch
- Switch to promptAsync + polling to avoid main session state change
- Matches background-agent pattern for consistency

* fix(sisyphus-orchestrator): only trigger boulder continuation for orchestrator-sisyphus agent

* feat(background-agent): add parentAgent tracking to preserve agent context in background tasks

- Add parentAgent field to BackgroundTask, LaunchInput, and ResumeInput interfaces
- Pass parentAgent through background task manager to preserve agent identity
- Update sisyphus-orchestrator to set orchestrator-sisyphus agent context
- Add session tracking for background agents to prevent context loss
- Propagate agent context in background-task and sisyphus-task tools

This ensures background/subagent spawned tasks maintain proper agent context for notifications and continuity.

Remove decodeState import and update OAuth flow to use simple state
string comparison for CSRF protection instead of PKCE verifier.
Update exchangeCode calls to match new signature (code, redirectUri,
clientId, clientSecret).

* fix(hook-message-injector): preserve agent info with two-pass message lookup

findNearestMessageWithFields now has a fallback pass that returns
messages with ANY useful field (agent OR model) instead of requiring
ALL fields. This prevents parentAgent from being lost when stored
messages don't have complete model info.

* fix(sisyphus-task): use SDK session.messages API for parent agent lookup

Background task notifications were showing 'build' agent instead of the
actual parent agent (e.g., 'Sisyphus'). The hook-injected message storage
only contains limited info; the actual agent name is in the SDK session.

Changes:
- Add getParentAgentFromSdk() to query SDK messages API
- Look up agent from SDK first, fallback to hook-injected messages
- Ensures background tasks correctly preserve parent agent context

* fix(sisyphus-task): use ctx.agent directly for parentAgent

The tool context already provides the agent name via ctx.agent.
The previous SDK session.messages lookup was completely wrong -
SDK messages don't store agent info per message.

Removes useless getParentAgentFromSdk function.

* feat(prometheus-md-only): allow .md files anywhere, only block code files

Prometheus (Planner) can now write .md files anywhere, not just .sisyphus/.
Still blocks non-.md files (code) to enforce read-only planning for code.

This allows planners to write commentary and analysis in markdown format.

* Revert "feat(prometheus-md-only): allow .md files anywhere, only block code files"

This reverts commit c600111597.

* fix(momus): accept bracket-style system directives in input validation

Momus was rejecting inputs with bracket-style directives like [analyze-mode]
and [SYSTEM DIRECTIVE...] because it only recognized XML-style tags.

Now accepts:
- XML tags: <system-reminder>, <context>, etc.
- Bracket blocks: [analyze-mode], [SYSTEM DIRECTIVE...], [SYSTEM REMINDER...], etc.

* fix(sisyphus-orchestrator): inject delegation warning before Write/Edit outside .sisyphus

- Add ORCHESTRATOR_DELEGATION_REQUIRED strong warning in tool.execute.before
- Fix tool.execute.after filePath detection using pendingFilePaths Map
- before stores filePath by callID, after retrieves and deletes it
- Fixes bug where output.metadata.filePath was undefined

* docs: add orchestration, category-skill, and CLI guides

* fix(cli): correct category names in Antigravity migration (visual → visual-engineering)

* fix(sisyphus-task): prevent infinite polling when session removed from status

* fix(tests): update outdated test expectations

- constants.test.ts: Update endpoint count (2→3) and token buffer (50min→60sec)
- token.test.ts: Update expiry tests to use 60-second buffer
- sisyphus-orchestrator: Add fallback to output.metadata.filePath when callID missing
