…audio goes to it Two defects, both found while porting this month's work into zyx, and both live in both copies. THE SAMPLES DO NOT START AT BYTE 44. Measured with `start()`'s own argv on macOS: ffmpeg writes a 26-byte LIST/INFO chunk between `fmt ` and `data`, so the first sample is at 78. `trim_trailing_quiet` was reading 34 bytes of encoder metadata as audio and cutting every clip 34 bytes early, and `tail_dbfs` was measuring its "have you stopped talking" window from the wrong floor. `data_offset` walks the chunks instead, and works on a file ffmpeg is still appending to, because only the two SIZE fields are left for an exit that may never come. `ours()` GUARDED ADOPTING A SERVER AND NOT SENDING TO ONE, which is the wrong half. The port is predictable, so a process that binds it first is handed every clip you record and believed about what was in it - and what comes back is typed at your cursor. `transcribe_warm` asks first now; the answer is cached, so the partial path pays a dict read and a `pgrep` twice a minute.

In `@murmurflow/dictate.py`:
- Line 956: Update the transcribe_warm ownership check around ours() so cached
process ownership is used only for availability, not authorization. Authenticate
the current listening endpoint with an authenticated local transport or complete
authentication before transmitting the multipart audio body, preventing
recordings from being sent to a replacement process that reused the port.
- Line 956: Update the audio-send guard around ours() to resolve the configured
port’s listener PID and verify that exact process is the approved whisper
server, invalidating any cached ownership result whenever the listener PID
changes. Preserve the existing missing-file behavior and add a regression test
covering a matching whisper-server process that does not own the listener.

…e zyx carries The extraction that produced this repo left ~450 lines living in two places: the wav on disk, what a sample measures, every threshold with its measurement, and the transcript rules. `voice-contract.json` pinned the MEASUREMENTS and did its job - no threshold drifted. Everything around them did, and the same two bugs had to be found twice. `murmurflow/speech.py` is that layer now, and it is byte-identical in zyx's `core/speech.py`. It reads NO configuration - the floors are arguments, because the two tools name their settings differently (`quietFloor` against `voiceQuietFloor`) and one line that has to differ is a file that is no longer shared. Enforced: a digest in `voice-core.sha256` that both repos carry, a test that fails the moment the file is edited, and `make voice-sync` (run from zyx) that copies it and rewrites both digests. WHAT IS NOT SHARED, and this suite caught it during the refactor: the whole-line hallucination blocklist. The shared table holds only what a PERSON NEVER SAYS - subtitle credits and audio markers, in every language whisper invents them in. "thank you", "you", "so", "bye" stay out of it and stay out of MurmurFlow: this tool types what a person says, so a swallowed sentence reads as broken hardware. zyx passes them in as its own extras, which is right there for the opposite reason. `deliberately_divergent.hallucination_list` is a parameter now, not a paragraph, and a new test fails if one of those words ever reaches the table.

changed the title
…t path is shared Everything from the key to the transcript is one implementation now, byte-identical with zyx's copy of it: `speech.py` (the wav on disk, the recorder, the warm server, the transcribe path, the thresholds, the transcript rules, `resolve_bin`, `pick_input`) and `gesture.py` (the intent delay, the chord abort, the press-to-press pairing, the tap/hold line). 1,519 lines that were living twice. The seam is arguments and never configuration: `speech.Setup` for the engine, `capture=` for this platform's own ffmpeg input args, `held()`/`since_keydown()` for the key. So the shared files know nothing about dshow, avfoundation, `quietFloor` or `voiceQuietFloor` - which is exactly what lets them be the same bytes - and the platform package keeps doing the job it was extracted for. WHAT THE MOVE FOUND, in each direction: - `ours()` guarded adopting a server and not sending to one (fixed in the commit before this one, in both); - the samples start at byte 78, not 44 (same); - MurmurFlow's hold floor slept its REMAINDER and zyx's slept the whole floor again, so zyx's shortest holds took nearly twice as long to answer. This repo's own test pinned the better one and now pins it for both; - "Mikrofon" was matched here and not there. Deliberately still two: `bind_trigger` (the hint it returns is the product's own words), `transcribe`'s cold fallback, `Result`, `_cfg`. Enforcement: `voice-core.sha256` carries a digest per shared file, a parametrised test fails the moment either is edited alone, and a second test forbids configuration inside them. `make voice-sync` is run from the zyx checkout and writes both repos.

This PR is two commits: the defects, then the de-duplication they exposed.
1. Two defects, both found while porting this month's work into zyx, both live in BOTH copies
The samples do not start at byte 44. Measured with
start()'s own argv on macOS: ffmpeg writes a 26-byteLIST/INFOchunk betweenfmtanddata, so the first sample is at 78.trim_trailing_quietread 34 bytes of that metadata as audio and cut every clip 34 bytes early;tail_dbfsmeasured its "have you stopped talking" window from the wrong floor.data_offset()walks the chunks instead, and works on a file ffmpeg is still appending to.ours()guarded ADOPTING a server and not SENDING to one. That is the wrong half: the port is predictable, so a process that binds it first is handed every clip you record and believed about what was in it - and what comes back is typed at your cursor.transcribe_warmasks first now; the answer is cached, so the partial path pays a dict read and apgreptwice a minute.2. One copy of the speech core
Those two bugs were in both repos because ~450 lines were in both repos.
murmurflow/speech.pyis that layer now - the wav on disk, what a sample measures, every threshold with its measurement, and the transcript rules - and it is byte-identical in zyx'score/speech.py(ZyxWorks/zyx#1283).quietFlooragainstvoiceQuietFloor) and one line that has to differ is a file that is no longer shared. A test in each repo pins it.voice-core.sha256(both repos carry the same number), a test that fails the moment the file is edited, andmake voice-sync- run from the zyx checkout - named in the failure.Gate
ruff clean, mypy clean, 213 tests pass. New: a wav shaped exactly like the recorder's own (LIST chunk and all), a
transcribe_warmthat refuses to open a socket when nothing of ours holds the port, the digest check, the no-configuration check, and the blocklist check.mainis yours to merge - this is the release branch.🤖 Generated with Claude Code
