MUTABLE DREAMS 1.2 — PRIVATE FINAL CHECKS, 27 OCTOBER 2026
Installed identity: FM-1_710010200
Installed SHA-256: 828891e0f506d6a07ee0c6fa844e54207985c464e0f2d9cbb423e73ae522f7fb
This is a private candidate. Published 1.0 and 1.1 remain unchanged.

RESULTS ON THE ACTUAL FM-1
29 controlled audio cases; 31 additional assertions; 731.7 measured playback seconds.
No new xruns, overloads, nonfinite audio, dropped commands or USB capture errors.
Highest audio callback: 88.39% of its deadline.
Case: Six Harmonic plus grains and full effects with animated editing.
All fifteen engines, six-track combinations, shared effects, animated editing,
short staggered gates, 32-step phrases, warm Biomes and grain sizes crossing 20
were exercised. Every held function-button guide opened; release did not execute
its short action. Dense patches may intentionally use ECO. These scoped tests
do not certify every combination, unlimited polyphony or multiweek uptime.

SEQUENCER, BANKS AND RECOVERY
15 sequencing/storage checks passed: keyboard and USB step entry, velocity,
live overdub duration, stop/disarm, four deterministic generators, track isolation,
live JSON-format snapshot roundtrip and exact User Biome save/load/name recall.
The original slot was restored immediately; all 22 saved objects and the owner's
live patch match the backup byte-for-byte.
Exact 1.2 -> verified Stock V15 -> exact 1.2 passed. The complete bank restore
was physically confirmed with SEL and checked against the pre-update backup.
The first strict test harness stopped at the stock loader's different USB name
before writing; its ota-FM-1_015 identity was verified and the harness corrected.
Only the identified Mutable Dreams device and its own loader ports were opened.
Syntherella was not opened or changed.
Physical cold start: PASSED; saved data, name, preferences and stopped startup verified.

BROWSER AND OFFLINE
Owner confirmed warm sound, visible controls, own sequence editing, browser-slot
save and reload on the exact packaged browser instrument. Browser and hardware
banks are separate. Current host/WASM, 23 pages, held guides, transfer/storage,
legacy imports, editor serialization and Density synchronization checks passed.
The prior full DSP/extreme-patch suite remains applicable: DSP source unchanged.
New unsigned elapsed-time tests cover clock rollover for uploads, overwrite
confirmation, help-related UI messages, intro, pulses and frame cadence.
This is simulated boundary coverage, not an actual 49.7-day endurance run.
The browser installer now rejects multiple FM-1 candidates before opening ports.
Visible installer check: owner confirmed successful same-build reinstall; cold-start verification checks retained data.
No blanket compatibility claim is made for every third-party firmware.

RESOURCES
Flash image 453732 / 581564 bytes; 127832 free.
Static RAM 73000 / 98304; 25304 free.
Audio pool 334872 / 344064; 9192 free.
The display remains physically 240 x 240. Clearer antialiased lettering and
parameter-responsive animation improve presentation without extra screen pixels.

VIDEO
136-second, 1080p private review film, calm male English narration, six chapters.
Firmware views recaptured from the current native application; sound rendered
from its DSP, not claimed as a device recording. No stock-firmware product photo.
Measured mix: -17.8 LUFS integrated, -2.9 dBTP. Subtitles and transcript included.
Quiet Arrival is the introduction; Terrassentanz belongs to Syntherella.

REMAINING LIMITS / RELEASE TASKS
- Final owner listening review of the warm Biomes and isolated loud-note concern.
- Physical TRS-MIDI cable test remains unavailable; USB and simulated TRS checks do not replace it.
- Final film listening/subtitle review and future 1.2 website/release publication; nothing public is changed by this private preparation.
