Context
Eos's review of PR #19242 (review 5325187459, approved, merged at dev 6eca69beb9) named a reachability gap that predates that PR: VesselConversion#resolveConversion decides exit on a tri-state pointerExitedTarget — true reverts at once, false holds through a lapsed claim, null / undefined falls back to strict claim loss — but no production caller supplies it. On dev the symbol occurs only inside src/dashboard/dock/window/VesselConversion.mjs; DragCoordinator#onDragMove feeds pointerInTarget: Boolean(claimed?.zone) and TabSortZone#resolveRemoteDragTransition samples with pointerInTarget alone. Production therefore reaches exactly one of the three documented behaviours; the other two exist only in DockVesselConversion.spec.mjs ("a lapsed claim is not a departure"). The tri-state landed in fd8003695b for #16497 (the film's dwell flicker: a claim expiring during a pause), on the premise that a consumer would supply exit evidence; none did.
A second boundary Eos recorded, documented intent without an arm: !measurable short-circuits before the tri-state is consulted, so one frame with a degenerate rect (a target mid-open reporting height: 0, a popup not yet laid out) reverts an admitted conversion immediately, even while an observer would report still-inside. The grace covers the claim dimension, not the measurability dimension.
The Problem
A JSDoc that describes three behaviours where production can reach one is a claim surface without a mechanism — the same family as an uninstalled plant. A reader trusting the "observed still-inside holds" clause would expect a paused hand to keep its conversion through a lapsed claim; what actually protects the pause today is that no sample is taken while the pointer is still (moves stop, the arbiter expires, the next move re-claims), not the tri-state.
Design authority
ADR 0029 §2.8.6: "leaving the claim may resume DETACHED_MOVING only after strict re-show admission" — exit is bound to the claim. #16497's mechanism ("a paused pointer is not a departure") is the reason the tri-state was added; whether it needs a supplier or should go is this ticket's decision. Decision Record impact: aligned-with ADR 0029 either way (no sentence changes).
The Architectural Reality
src/dashboard/dock/window/VesselConversion.mjs — resolveConversion(record, pointerExitedTarget), sample({pointerExitedTarget, …}), the JSDoc naming all three arms.src/dashboard/dock/interaction/TabSortZone.mjs resolveRemoteDragTransition — the only production sampler; it holds vesselConversionTargetRect and receives logicalSourceRect but not the raw pointer.src/manager/DragCoordinator.mjs onDragMove (~:1017) — has screenX / screenY and the target's inner rect; builds the frame the zone resolves.test/playwright/unit/dashboard/DockVesselConversion.spec.mjs describe('a lapsed claim is not a departure') — the spec-only arms.
The Fix (decide at the PR, one of two)
- Delete the tri-state:
resolveConversion reverts on claim loss and on unmeasurable geometry; the JSDoc says so; the describe block goes. Smallest, and the pause is already safe because a still pointer produces no sample (state this in the JSDoc). Recommended unless a producer is wanted.
- Supply it: the coordinator threads the raw pointer into the transition frame, the zone derives
pointerExitedTarget against vesselConversionTargetRect (inside → false, outside → true) and passes it to every sample. Makes the #16497 clause real; costs one field across two files.
Either way, add the measurability arm: a converted sensor fed one degenerate frame reverts immediately with no grace (pin the decision so the next reader finds it), and — if the flicker class shows up in the operator's hand test — that is where to look first.
Acceptance Criteria
- AC-1:
grep -rn pointerExitedTarget src apps returns either nothing (delete) or a production supplier plus the sensor (supply); the sensor's JSDoc describes only reachable behaviour.
- AC-2 (unit): the spec-only exit arms are removed or made reachable through the zone's sampler with a red-first arm; the measurability arm exists.
- AC-3:
unit/dashboard green.
Out of Scope
- The named trade Eos recorded: entry has no dwell or travel floor, so a vessel dragged in a straight line across two popups converts through both — intended (pointer authority), to be confirmed by the operator's hand test; a headed falsifier is the region probe with a third popup if it ever needs one.
- #19243 (a still pointer's drop zones after the park) — Ada's, disjoint files.

Decision: use the ticket's delete option. At dev@7ff8467baa, git grep pointerExitedTarget origin/dev -- src apps finds only the sensor; every production TabSortZone#resolveRemoteDragTransition sample supplies the claim flag alone. The zone already owns bounded claim-miss grace and passes pointerInTarget: true during visual retention while refusing a stale commit. No pointer supplier or new grace layer is needed.
AC-2's measurability requirement is already covered by the live-geometry collapse/recovery test and the invalid-rect test in DockVesselConversion.spec.mjs; retain them. Remove the test-only observed-exit branches and update the sensor documentation to describe the production claim flag. Async admission and strict re-show behavior stay in their existing owner.
