What Changed

Select the newest live provider session when planning a model switch. Stopped and errored session records remain in history but no longer hide an older session that needs restarting.

Why

When the newest record was stopped or errored, a model change requiring restart_and_resume released no session: selection chose the dead record, while release correctly excluded it. The live process was left running. This focused fix targets Orchestrator V2 (#2829) and preserves native provider-thread history fallback.

Validation

  • Reproduced both stopped/error cases before the fix: expected live session release, received an empty list.
  • vp test run apps/server/src/orchestration-v2/ProviderSwitchService.test.ts — 4 passed.
  • Targeted type-aware lint/type checking and formatting checks passed for both changed files.
  • Rebased onto the latest V2 branch before publishing.

Implemented by Grok 4.6 through Grok Build, with Codex supervision, patch application, and verification.

perf(web): keep timeline minimap animations off the main thread
0ee69f0 
A renderer performance trace showed the minimap strips as a standing
source of main-thread frame work: each strip transitioned
background-color (paint) and width (layout), and both fire constantly —
scrolling or streaming flips a band of in-view states at once, and the
hover fisheye animates several widths at a time — so any interaction
kept a 60fps style/layout/paint pipeline running.

The strip now animates only compositor-friendly properties: width tiers
are scale-x on a fixed-width box, and the in-view highlight is a bright
overlay faded with opacity. The scroll handler also skips no-op
data-in-view attribute writes, which previously re-dirtied style state
for every strip on every scroll tick.

feat(orchestration): port thread title regeneration to the v2 runtime
6211c05 
Follow-ups from the main merge:

- Migration numbering: main's 035_ProjectionThreadTitleRegeneration is
  released and keeps its id; this branch's unreleased v2 migrations shift
  to 036-044 instead (a released migration can never be renumbered).
- thread.metadata.update accepts regenerateTitle: true arms an in-flight
  titleRegeneration marker on the thread payload (requestId + startedAt),
  a landing title or explicit false clears it. The marker projects onto
  thread shells and through the client-runtime shell model, so the
  sidebar's Regenerating state works unchanged.
- New ThreadTitleRegenerationService worker reacts to armed markers on
  the live domain-event stream (so ws, MCP, and mobile dispatches all
  behave the same): builds a newest-first conversation digest from the
  v2 projection (8k-char budget, retained attachments — ported from the
  v1 reactor), generates via TextGeneration, and lands the title with a
  follow-up metadata update. Failures clear the marker and log.
- The server advertises threadTitleRegeneration again, and the client
  updateThreadMetadata dispatches regenerateTitle-only updates.

fix(orchestration): promoted queued messages keep the queued_turn intent
960d91e 
The turn item materialized when a queued run is promoted was emitted
with inputIntent "turn_start", but the deterministic replay driver (and
the recorded queued_turn fixtures) expect "queued_turn" — the mismatch
stalled replay before the queued run could start, leaving run 1 waiting
and run 2 queued forever in all five queued_turn fixtures.

refactor(orchestration): split thread-not-sendable into typed errors
b10a121 
Effect service conventions: ThreadManagementThreadNotSendableError
carried an Archived/NoSteerableRun reason union and switched on
reason._tag inside the message getter. Modelled as two error classes
(ThreadManagementThreadArchivedError, ThreadManagementNoSteerableRunError);
both still map to the MCP thread_not_sendable failure code.

test(server): cover v2 thread title regeneration
4458102 
Ports the deleted v1 ProviderCommandReactor title coverage onto the v2
service: marker arming/clearing via thread.metadata.update, superseded
requestId no-ops, digest-driven regeneration, the "New thread" and
unchanged-title fallbacks, generation failure, and missing initial
messages, plus unit tests for formatThreadTitleContext.

fix(test): keep codex replay recovery off the repo checkout
d9e962c 
The codex resume test was the only replay scenario without a
runtimePolicyOverride, so its checkpoint scope cwd fell back to
process.cwd() and baseline capture ran real git over the entire
checkout. Locally the capture short-circuits on checkpoint refs left
behind by earlier runs; on a fresh CI checkout it is a cold multi-second
capture that outlives the scenario wait budget, failing await_thread_idle
while the run is still mid-checkpoint. Point the fixture's turn/start
frames at the <workspace> placeholder and checkpoint a throwaway git
workspace like every other replay test.

Scenario waits are also wall-clock-bounded now: the iteration budget
counts event-loop turns, which burn at full speed while git/fixture IO
is in flight, so exhaustion additionally requires a 60s real-time
deadline to pass.

Main owns migration numbering: 036_ProjectionThreadsPinned landed on main,
so the v2 migrations shift from 036-044 to 037-045. Release path runs all
of main's migrations first, then the v2 stack.

fix: port main fixes stranded by the v2 rewrite
98b7b33 
- Port thread pinning (pingdotgg#5312) into the orchestration-v2 command pipeline:
  thread.pin/unpin commands, thread.pinned/unpinned events, pinnedAt on the
  v2 thread state and projected shells, promotion semantics (pin clears
  settle/snooze, settle clears pin) matching the v1 decider, and client
  pin/unpin operations in the v2 dispatch style.
- Port the regenerated-title context anchoring (pingdotgg#5365) into
  ThreadTitleRegenerationService: pin the first user message ahead of the
  retained tail when the digest is truncated.
- Re-apply the right-panel controls positioning from pingdotgg#5260 to the v2
  ChatView title bar controls.
- Repair merge artifacts: committed conflict markers in BranchToolbar,
  duplicate capability keys, duplicate CommandPalette import, v1 turn
  naming in DiffPanel's focus-refresh effect, onSend signature merge.

fix: port main fixes stranded by the v2 rewrite (round 2)
68d0b76 
Native subagent observability (pingdotgg#5219), wired per its spec's v2 merge plan:
- getWorkflowScript RPC re-homed onto the v2 WS surface (contracts, rpc
  group, ws handler, auth scope, client atom).
- AgentsPanel fed by the spec's mapper swap: projectedSubagentsToRuntime
  maps orchestration-v2 subagent entities into the panel model;
  deriveAgentPanelModel's v2Projection leg is now live and the v1 fold
  never runs. Agents surface wired into ChatView + RightPanelTabs.
Other ports and reconciliations:
- Shell reconnect-loop fix (pingdotgg#5561) ported into the v2 shell sync
  (same-session resubscribes resume from the in-memory cursor), with the
  cursor-resume regression test adapted to v2 fixtures.
- Mobile end-follow latch (pingdotgg#5566) ported onto the v2 ThreadFeed.
- Claude ede_diagnostic interrupt classification (pingdotgg#5557) ported into
  ClaudeAdapterV2 (aborted_tools/aborted_streaming => interrupted; CLI
  telemetry never becomes the failure banner). pingdotgg#5559 needs no v2 port
  (unknown system subtypes are already ignored).
- Plan sidebar removed from the v2 ChatView/ChatComposer per main's
  plans-fold-into-chat rework (pingdotgg#5558); rightPanelStore stays at main's
  surface set.
- SettingsPanels rebuilt as main's refactored version plus the branch's
  composer-context setting; sidebar snooze respects the time format
  (pingdotgg#4438 follow-through).
- v1-only leftovers deleted: zombie v1 adapters/ingestion/tests the v2
  rewrite removes, the v1-bound transfer-budget CI harness (pingdotgg#5350, needs
  a v2 rebuild), and main's v1 client pagination machinery (pingdotgg#5493 client
  side; the 037 keyset migration is kept — server-side v2 windowing is a
  follow-up).

Approvability

Verdict: Approved at 2b9c824

Macroscope's review found this PR approvable — This is a small, self-contained orchestration bug fix that prevents dead session records from hiding a live session during model changes. The added tests cover both stopped and errored records, with no broader API, schema, deployment, or configuration impact.
