U3: per-run IR resolution feeds the core column-agent resolver at the
runCustomNode seam; override supersedes node agent/model/persona wholesale,
defer fills bare nodes only; adoption and fallback are audited via logEntry;
raw-CLI nodes log a skip. Also fixes the customInstructions persona drift —
node-level executor:"agent" persona injection now uses the typed
soul/instructionsText fields (KTD-6).
U1+U2 of the column-agent plan: WorkflowColumnAgent on WorkflowIrColumn
(defer/override), template-subgraph column validation, v2-only-feature
registration, plugin-sdk type parity, and the shared core resolver with
instanceNodeId format ownership moved to core.
Pure engine code (no HTTP) for the CLI agent executor:
- state-machine.ts: authoritative per-session state machine implementing the
HTD diagram (starting→ready→busy⇄waitingOnInput→done; done→busy follow-up;
dead-classification choice → killed/userExited/authFailed/resuming; resume cap
of 2 with backoff → needsAttention). Positive completion is distinct from idle
(idle never produces done); inactivity stall backstop re-armed by output/
telemetry events (no fixed turn timeout); termination classification helper for
all five paths; per-turn latches reset between turns. Persists every transition
via CliSessionStore (the transient `resuming` machine state maps onto the U1
`dead` store enum) and exposes a throttled `onStateChange` subscription for the
later SSE bridge — no dashboard imports.
- telemetry-hub.ts: in-process ingestion contract (ingest(sessionId, event)) for
the U17 route and log-tailing adapters. Mints high-entropy per-session hook
tokens (issueToken/validateToken/invalidate); rebuilds the registry only from
live sessions in CliSessionStore so stale tokens for non-live sessions never
validate; a token validates only for its own session. Bounds everything
ingested: per-event size caps, per-turn count caps (lifecycle events exempt),
ANSI/control stripping before pattern matching, and secret redaction that
survives chunk boundaries via a held-back carry window (redactSecrets from
@fusion/core).
Tests: 35 new (state-machine.test.ts, telemetry-hub.test.ts) covering AE1/AE2,
stall backstop, all termination paths, resume caps, token registry, two-turn
latch reset, oversized capping, ANSI stripping, and cross-chunk redaction.

Engine-owned PTY lifecycle for CLI agent sessions:
- adapter.ts: CliAgentAdapter interface (launch/env-allowlist builders,
capability flags, readiness detection, injection formatter, resume builder,
telemetry wiring) + CliAdapterRegistry with typed unknown/duplicate errors.
- session-manager.ts: CliSessionManager owning node-pty processes via the U16
shared loader. Byte-bounded scrollback ring (default ~512KB), single
serialized write queue shared by injections + user input (FIFO, deferral in
quiet windows), latest-active-client resize, scoped-SIGKILL process registry
on process exit (never port 4040), explicit async attach interface
(scrollback + AsyncIterable<Uint8Array> + write/resize/detach),
requestPause/requestResume watermark hooks, separate concurrency pool with
typed CliConcurrencyLimitError at the ceiling.
- Security: bracketed paste only when ?2004h observed; unconditional control-char
neutralization on the raw path; user keystrokes bypass neutralization.
- Persists lifecycle into the U1 CliSessionStore (create on spawn, update
state/termination).

- restore customFields on unarchive; reconcile all occupants on field-schema edits (store.ts)
- serialize per-field saves + controlled inputs in TaskFieldsSection (race fixes)
- fn_workflow_get includes layout; Array.isArray guards in validateCodeNodeSources
- per-instance graphStepActiveContext keying; rebase in instance worktree; clear run-once memo on RETHINK
- GET /api/step-parsers + registry-backed parser select (plugin parsers reachable from editor)
- translate new workflowNodes/workflowFields strings across all 5 non-en locales

Harden executor worktree recovery coverage against fixed-path collisions.
- create a unique temporary root for the stale unregistered worktree test case
- derive the stale worktree path from that temporary root instead of a shared /tmp/test path
- initialize TaskExecutor with the same temporary root so setup and assertions stay aligned

- db.ts: restrict migration-105 orphan-step cleanup to JSON arrays
(json_type guard so json_each can't expand objects/strings)
- project-engine.ts: requestInterpreterMerge throws on null task lookup
instead of casting null into MergeResult (seam converts to clean failure)
- executor.ts: truncate dual-observe shadow stage walk at the live terminal
stage so healthy in-review tasks don't record a phantom merge transition
