Completes the pair started in #2498. That landed the outcome; this makes the engine's reaction consume it. ## The bug `onSpecifyComplete` fired on **every** finished specification, because the seam announcing it fired unconditionally. So a card parked at the manual plan-approval gate — finalize writes `status: "awaiting-approval"` and **returns early**, before the release move — was logged as `Specified X → todo` and had a Plan Review run armed for a plan the operator had not approved. #2491 stopped the **seeder** from acting on that, defensively, at the seeder. This removes the reason it was ever asked. Both layers are deliberate and neither is redundant: - the seeder guard covers **every caller**, including self-healing's re-seed; - this one stops the engine doing work nobody asked for, and stops it telling the operator something false about their own board. `released` is the only outcome that licenses arming a run — the only one meaning the card crossed into the hold column (or was already resting there, plan-in-place) and is the graph's now. `parked` belongs to a human; `withheld` belongs to the caller's retry budget. ## The event still fires on every outcome Deliberately. Dropping the reaction for a non-release would also drop the runtime's `recordActivity()` idle signal, and a reaction that silently does not happen is harder to reason about than one that happens with an accurate payload. R5's division of labour: **the seam announces, the subscriber decides what a given outcome licenses.** ## Why there is a new extracted function `reactToSpecificationComplete` is pulled out of the inline `InProcessRuntime` callback for the same reason the continuation drain was in #2491: the callback is built inside a class whose construction attaches to the real central project registry, so no test could distinguish *"the reaction respects the outcome"* from *"the reaction ignores it"*. **Revert proof:** with the outcome gate removed from the reaction, **5 of 8 fail**. ## Two call-site decisions worth naming **`tryFinalizeExplicitDuplicateMarker` reports through a mutable ref, not a widened return type.** Its boolean answers a *different* question — "was this a duplicate marker at all?" — and 16 existing tests assert it directly. I tried the widened return first and it turned all 16 red. Expectation edits are exactly how a behavior change travels disguised as churn, so I backed it out. **This diff touches zero existing test expectations.** **A duplicate-marker redirect reports `parked`**, which is accurate: it deletes, flags, or clears the marker; it never releases the card into the hold column. ## A fixture note — third of this shape on the program My "task vanished between release and reaction" case passed `undefined`, which triggered the harness **default parameter** and silently handed the reaction a live task — making it a duplicate of the control rather than the case it claimed to be. It now passes `null`, with a comment saying why. Running tally of near-false-greens on this unit, all the same family: a fake that ignores its predicate (#2491), a stub that ignores its callback (#2498), a default parameter that swallows the interesting input (here). Each was caught by the test failing for the *wrong reason* and being read rather than fixed. ## Verification | Check | Result | |---|---| | new suite | 8/8 | | 15 triage / planning / continuation suites | 361/361, **no expectation edits** | | `tsc --noEmit` (engine) | clean | | `pnpm lint` | clean | | `pnpm test:gate` | green (307 + 10 + 71) | | `pnpm check:changesets` | clean | 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>

Audience
The summary is the only content that appears in end-user release notes by default. Write for Fusion operators — describe behavior, fixes, and what changed. Avoid internal class names, file paths, and implementation detail.
