- workflow-graph-executor: wrap each post-merge walk() in try/catch so a malformed
post-merge IR / traversal error is logged and skipped, never flipping an already-
merged task to failed (non-blocking post-merge contract) [T9, real bug].
- Refresh stale FNXC comments now that graphNativePostMerge is default-ON and the
legacy merger post-merge path was removed (experimental-features, workflow-graph-
executor, workflow-graph-post-merge.test) [T6/T7/T8].
- Normalize FNXC timestamps to yyyy-MM-dd-hh:mm (TaskCard.test, taskProgress.test) [T2/T3].
- Changeset: category fix → feature to match the minor bump [T0].

Adds graph-native post-merge step execution behind experimentalFeatures.graphNativePostMerge
(default OFF — byte-identical behavior until enabled). After a successful merge-attempt
(the merge seam awaits the merge Promise), the graph runs post-merge optional-group nodes
and records phase:"post-merge" results, non-blocking. The merge-region traversal hop is
inert when the flag is off, and empty for builtin:coding even flag-on (its merge exits only
reach merge-region nodes or end), so the parity oracle holds. Optional-group recording now
derives phase + log prefix from config.phase (defaults pre-merge). Adds postMergeOptionalGroupNode
factory for migration/custom workflows. Legacy merger post-merge path untouched (U7b cutover).
Plan U7a.

Enabled optional-group nodes now upsert their outcome into the existing
task.workflowStepResults field keyed by node id, and emit [pre-merge] logs at
parity with the legacy runWorkflowSteps path. Disabled groups stay byte-inert.
Reuses the existing WorkflowStepResult type + store.updateTask path (no new
table/type/store method). Unblocks the unified progress bar for graph-run steps.
Plan U2.

- Reject failure-condition edges inside optional-group templates (the single-pass
walk surfaces template failures as the group's outcome, so an internal failure
edge was silently dead) — Greptile P2.
- flowToIr: a container/group node (foreach/loop/optional-group) is v2-only — its
presence now forces v2 serialization (an inserted optional-group on a plain
workflow no longer serializes as invalid v1) — CodeRabbit.
- Disabled optional-group bypass routes a plain success with no distinguishing
value, so an outcome:* edge can't preempt success routing (inertness) — CodeRabbit.
- Downgrade heuristic: presence of a legacy optionalSteps key (incl. []) keeps v2.
- Resolver docblock corrected (config-less groups resolve to a fallback entry).
- Strengthen tests: assert both inserted groups + v2 round-trip; failure-edge
rejection case.
- Changeset: bump to major (removed exported WorkflowOptionalStep type).
- Plan: record U7a as delivered in this cohort; only the workflow-step seam
infra removal remains deferred.

Code review found that enabling a built-in optional-group whose node id collides
with a WORKFLOW_STEP_TEMPLATES id (browser-verification) was silently bypassed:
resolveEnabledWorkflowSteps materialized a WorkflowStep row and stored its id
instead of the group node id, so the executor's enabledWorkflowSteps.includes(
node.id) check never matched. Pass the task's workflow optional-group ids through
untouched on both create-with-enable and update/toggle paths (new
resolveAllOptionalGroupIds + optionalGroupIdSet). Add colliding-id regression
tests. Also (review P3) record the group's own outcome on the disabled-bypass
path so a disabled group is fully context-inert, matching the enabled path.

Add an optional-group branch to runNodeAndTraverse beside foreach/loop: when
the group id is in the task's enabledWorkflowSteps it runs the template subgraph
exactly once (new single-pass runOptionalGroup helper, no rework/iteration);
otherwise it passes through to the group's children without executing the body.
Covered by a two-task divergence execution test plus single-pass, inertness,
and template-failure-routing cases.

Generalizes the foreach-only bounded-rework mechanism to the top-level
graph walk so the PR review loop (await-review -> pr-respond -> rework
back) is a legal bounded cycle: a kind:rework back-edge to a stacked node
returns a ReworkSignal the loop-head re-runs up to maxReworkCycles, then
routes outcome:rework-exhausted. Non-rework cycles still throw 'Cycle
detected' (safety preserved); foreach rework unchanged (shared core
constants). Adds createAutoMergeGateHandler (live entity re-fetch +
isPrEntityAutoMergeReady -> auto-on/auto-off). Pins R14: graph-executed
PR tasks merge through pr-merge, never the legacy queue. 122 graph tests
green.

Adds the three first-class PR workflow node kinds and their handlers via
createPrNodeHandlers(deps), registered in createDefaultNodeHandlers
(fail-closed pr-nodes-unwired when absent). GitHub ops are injected as
callbacks (PrNodeGithubOps) at all three CLI sites (daemon/serve/dashboard)
so the engine never imports the dashboard client (FN-3049). pr-create
routes open/failed as outcomes; pr-merge passes expectedHeadOid and never
writes 'merged' (reconcile corroborates); pr-respond delegates to an
injected respond callback (U5 fills the body). 10 tests.

Prompt nodes now support an executor kind: model (provider/model override),
agent (adopts a named agent's model + custom instructions), skill (prompt
becomes a skill invocation), and cli (named project script with the prompt in
FUSION_NODE_PROMPT — raw commands still never accepted). Per-node maxRetries
overrides the executor-wide default (capped at 10). Await-input nodes pause the
task with status 'awaiting-user-input' and the question as pausedReason; on
unpause the newest steering comment is consumed as the answer and exposed in
graph context.
Non-seam prompt/script nodes now dispatch to an injected WorkflowCustomNodeRunner
instead of throwing; gate nodes support an executable (prompt/script-backed) form
alongside the original context-gate contract. WorkflowGraphExecutor accepts the
runner via deps.
Add the Phase 2 workflow-graph interpreter scaffold and builtin coding IR wiring while keeping execution behavior unchanged by default.
- add BUILTIN_CODING_WORKFLOW_IR and builder in @fusion/core with coverage tests
- export new coding workflow IR APIs from core index
- add WorkflowGraphExecutor scaffold in @fusion/engine plus parity-focused test coverage
- document the flagged-off interpreter scaffold, parity gate, and v1 IR gap reconciliation in workflow docs
- include a changeset for published @runfusion/fusion
