- Added live tracking and stale status warnings for agent activity snapshots.
- Fixed text wrapping with ANSI escape sequences to defer style open sequences after whitespace.
- Added VirtualRenderScheduler for deterministic virtual-clock rendering tests.
Final review found `pendingRetryFallbackModel` unreachable. `servingModel`
returns `undefined` only when the session has no model at all, and the
pending getter required one, so the badge term guarding on it could never
fire. Its case — a fallback armed before anything has served — is already
answered by `servingModel`'s bootstrap, which names the current model and
flags it as fallback-routed. Removed, the same duplicate-surface cleanup
that removed `retryFallbackModel`.
Attribution now anchors on the session id rather than the session file. An
unpersisted session has no file, so two `undefined`s compared equal and
stale attribution survived `/new` and branch switches there; every real
switch mints a new id, persisted or not.
The cooldown-expiry restore keeps `#fallbackRouted` when the stored primary
selector cannot be parsed. Nothing is restored on that path, so the session
is still running on the fallback and its remaining turns are still fallback
work; clearing the flag reported them as the configured primary.
`executor-prewalk`'s fake session predates this work and never set
`servingModel`, so the prewalk hand-off stopped advancing the reported
model once the executor began reading attribution from the session. It now
mirrors the hand-off the way the other executor fixtures do.
- The IRC wake monitor from PR #7108 calls the observer on every kept-alive
subagent finalize; fakes across the executor suites predate the method
and threw during finalization (69 failures).
Tracked active subagent session model changes in progress snapshots so prewalk handoffs replace the starting-model badge.
Added regression coverage for a prewalk handoff and documented the fix.
Fixes#6083
- Updated prewalk gating in `AgentSession` to key the todo gate on active tools instead of registry presence, so deactivated todo tools no longer block prewalk handoff.
- Changed subprocess tool filtering so `todo` is stripped for normal subagents but retained when prewalk is armed, and propagated the prewalk state through tool-session setup.
- Added regression tests for restricted active-tool slates and prewalk/non-prewalk subagent tool propagation to verify todo is handled correctly in each case.
- Added schema and type updates for task-agent fields and model resolver settings.
- Extended discovery helper logic to carry resolved task-agent metadata through execution setup.
- Updated task/agent registration and execution paths to use the new capability/field data.
- Expanded test coverage for agent-field parsing, model resolution, and executor prewalk behavior.
