THE TRANSCODE CACHE HAD NEVER HIT. `video::transcode` has carried one since P4 -- a `.cmd` sidecar with the command, the source size and the channel count -- and `main.rs` clears the output tree wholesale immediately before the check, deleting the sidecar and the file it stamps. Six exports in this session paid the full Theora encode and produced five byte-identical files, roughly 48 minutes. Nothing reported it, and nothing could: a cache is silent either way and the only symptom is a wall clock that looks like the job being slow. The wipe now spares `video/` and `prune_videos` deletes anything in it this run did not claim, so the wholesale guarantee is kept rather than traded. A re-export is 20 s. SETTLE TIMES, MEASURED, and they refute more of my row than they confirm. The principle holds -- the title's rest.t is 251 units = 4.183 s where its art finishes at ~2 s -- but "everything the sequencer paces off that landmark is therefore late" does not. Measured the port the way the game was measured, by VISIBLE SPAN rather than arrival-to-arrival: publisher wordmark port 4.25 s game 4.297 / 4.604 / 4.370 developer logos port 3.50 s game 3.508 / 3.503 / 3.366 black hold port ~0.25 s game 0.2 - 0.3 title -> plate port 2.000 s (declared 120 units) game 2.247 s Dead on. My earlier reading compared the port's transition timestamps against the game's visible spans, which differ by the exit ramp plus the black hold -- the whole of the discrepancy I was about to chase, and the same definitional trap that cost this corpus 0.48 s on the plate delay. Nothing in the sequencer is changed. `dwell_seconds` stays null, now for a measured reason rather than an absent one: `timing.json` said "if a capture ever times the real boot, this is where that number goes", and the answer is that nothing goes there. Not authored, deliberately: an (A)->menu dwell, which measures 3.763 s and contains a 1.53 s guest load stall on a cold cache; and the menu build-in and (B)->title, which rest on one run where the port is already within ~0.1 s. THE VOICE PRESENTATION MOVED TO authored/, because the recommendation behind it was withdrawn as self-contradictory and the choice is now unambiguously mine. `voice.presentation` = `loudest`, and the reason to switch is a measurement, not a preference: ADV chunk 1 is MONO-IN-STEREO and chunk 2 is DUAL-MONO, so chunk 2's extra bytes encode a duplicate channel rather than fidelity. That explains the byte-rate difference and removes the only argument for `highest_rate`. ADV's dialogue now exports at +0.3 dBFS instead of -8.7, which is the SE bound's documented decode overshoot on a wave mastered at full scale.

Authored decisions
Everything here is a decision we made, not something the disc said. It is
hand-written, committed, and survives a re-export — unlike export/, which is
regenerated wholesale and must never be hand-edited.
Every entry carries a why. When the RE agent decodes the real answer, delete
the entry and let the exporter emit it; that deletion is the measure of
progress.

question each placeholder is standing in for.
