Context
Sub of #15252, the continuous flagship film. The tear-out-first screenplay is merged through #19097 / PR #19107 at e6b7b10556ce4e8cbe4a757e35b013c02f52ae9e. Dialogue draft 2 is recorded on the parent; voices are Emmy/marin and Mnemosyne/nova, using the recovered July production pipeline.
The first timing rehearsal generated 23 immutable utterance WAVs. Measurements: the mid-birth Emmy line is 4.000 s, the following Mnemosyne question 2.350 s, and the re-entry invitation 2.800 s. The full audio-only listening preview is 67.500 s with declared turn gaps; that is not a finished film duration or visual acceptance receipt.
The Problem
NativeGestureDriver.executeTearOutStep has no stationary post-birth hold. After the real birth gate, it performs the survival moves and immediately re-enters or releases. The narration can therefore describe a window and a held pointer after that visual state has already ended.
Changing the cue's pause.ms does not solve this: TourRunner starts the cue and pause concurrently, then awaits host settlement. targetSeconds is a screenplay budget, not a runtime timer. Slowing the entire pointer path would conflate a deliberate visual hold with gesture motion.
The Architectural Reality
apps/workstation/tour/NativeGestureDriver.mjs#executeTearOutStep owns the witnessed pointer bracket and native birth/re-entry/release phases.GestureDriver.runGesture retains dispatched-input cleanup, and driver.trap(driver.timeout(...)) is already the cancellable pacing idiom used by the preview dwell.apps/workstation/tour/fiveBeatFilm.mjs owns app-specific cue options; stable scene/cue IDs bind the separate dialogue assets.- Existing cue-free
pause steps can hold a settled result. A new narration engine or runner vocabulary is unnecessary.
test/playwright/unit/apps/workstation/GestureDriver.spec.mjs owns driver lifecycle/cleanup controls; the existing film whitebox witness owns the continuous real journey.
The Fix
Add an optional, default-zero birthDwellMs to the existing tear-out executor. Place it after confirmed birth/survival and before re-entry or terminal release. Keep the pointer down without synthesizing movement during the hold. Use the existing registered timeout/trap and cleanup path so cancellation/destruction cannot leave input pressed.
Use the measured dialogue map to set the film's hold and ordinary post-receipt pauses. Preserve the opening's short introduction and all existing scene/cue IDs. Correct the cold-open wording or timing against its measured duration before calling the combined rehearsal ready; the current eight-word line measures 4.650 s against a ≤3 s target.

Acceptance Criteria
Out of Scope
Final video capture/publication; whole-film acceptance; new runtime audio playback or a generalized narration runner; the independent renderer issue #19110; unrelated-root isolation #19103.
Avoided Traps
A longer cue-bearing pause does not create a mid-gesture hold. Poll-attempt ceilings are not pacing. A successful audio decode is not a full perceptual listen or a picture-sync proof. Keep old attempts immutable and reuse the July pipeline.
Decision Record impact
none — app-owned choreography pacing on existing gesture/lifecycle primitives.
