A random-input property test compares the equal runs against a dynamic-programming
LCS: a diff that is valid but not minimal would turn real agreement into disputes
the model is then asked about. A 6,500-word, 380-edit case mirrors a real hour.

Keeps the word as written, keys it without case/punctuation/hyphens/plus, joins a
lone dash or full stop to its neighbour so it is not a word the engines can
disagree about. Red: package reconcile does not exist.

Proposed, decider pending. Two local engines on one WAV; word-level diff with
pianissimo as the base (readability and timing, NOT accuracy -- that was a tie);
trivial disputes resolved without a model; the rest adjudicated by a LOCAL model
(alias must start koala/ or iguana/) whose only freedom is choosing between the
two readings. Reconciliation never fails a job; the page says what was done and
lists the uncertain spots. Off by default. Validation: re-upload the real
recording and keep the feature only if the reconciled reading is right >= 85% of
the time and no worse than the better single engine.

Eleven local models, 120 calls each, scored against the speaker's blind answers
on 30 disagreements, with pass criteria fixed before the run. gemma4-31b (97%)
and gemma4-26b (92%) pass; nothing else clears accuracy and order-consistency.
Records why 31b is slow (MLX gives the same speed; Low Power Mode is the
unproven suspect) and the caveats: 30 items, one recording, thinking models
under-budgeted. Aggregate numbers only; this repo is public.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A near tie on accuracy (blind A/B by the speaker: 17 vs 13 on the 30 spans that
change meaning) and a 6x difference in speed (40 s vs 4m08s for 63.7 min).
Different error profiles: pianissimo better on terms and numbers, kb-whisper on
everyday words. Aggregate numbers only -- no transcript text or domain terms,
this repo is public. Also records the mid-word wrapping bug the comparison found
and its fix.

whisper.cpp wraps at ~60 chars and can wrap inside a word; the response's text
field joins segments with newlines, so chat saw 'nyt' / 't godkännande'. Text
is now rebuilt from the raw segments: concatenated when any segment carries a
leading space (whisper.cpp), joined by a space when none do (berget's sentence
level), whitespace collapsed; the text field is only a fallback.
Checked against the first real one-hour transcript with pianissimo's vocabulary
as an independent yardstick: 36 spans changed, 31 now consist entirely of words
pianissimo also produced, words unknown to pianissimo fell 224 -> 177 and word
agreement rose 92.4% -> 93.1%. Five rejoined spans still contain an unknown
word (names/loanwords or an unlucky glue) -- a residual risk, small.

Found by comparing the first real one-hour transcript against pianissimo:
whisper.cpp wraps at ~60 chars and can wrap INSIDE a word. The continuation
segment has no leading space, the text field joins segments with newlines, and
a segment can be a lone '.'. Measured 2026-10-01: 7% of segments (96/1332) in a
synthetic hour, 42/1302 lines in the real one. My earlier tests used short
sentences and could not see it. berget's segments are whole sentences with no
leading space, so the two backends need different joins.
Red: Text still joins by newline.

Rejections are synchronous and leave no row, so an operator could not tell 'the
user never retried' from 'the page refused it' (it happened during the first
real-recording trial). The reason is operational; the filename and title are
the user's private content.

Run 2026-10-01 with 82 s of synthetic Swedish muxed with black video (H.264 +
AAC .mp4, built with the real ffmpeg): accepted, had_video=true, transcribed by
iguana/kb-whisper, the page said only its audio was used, and chat answered.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A Teams meeting with the camera off is still a video file. It is accepted, only
its audio is transcribed, and the page says so in queued, transcribing, done and
failed -- not just at the end.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
My assertion expected a lowercase 'only'; the sentence begins 'Only'. The user
facing wording is unchanged.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Up and down are one commit: golang-migrate pairs them. RLS is unchanged: the
column is on the already-FORCE'd table, so the exact-set isolation test still
holds.

Video with no audio is rejected for having none. A file with a video track is
accepted and marked had_video; every state of its page (queued, transcribing,
done, failed) says only its audio was used and the video was discarded, and a
plain audio file shows no such notice.
Red: the had_video column does not exist.

A Teams meeting with the camera off is still an .mp4 with a video track.
Video with no audio is now rejected as having no audio.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
The first draft rejected video and named #28. The maintainer's first real
recording -- a Teams meeting with the camera off -- is still an .mp4 with a
video track, so that rejected the primary use case. Decision 1 and 4 now:
accept, extract audio only, discard the video, record had_video, and tell the
user. A file with no audio stream is still rejected. Video features stay #28.
In-place amendment: the ADR is still Proposed.

The upload is attacker-supplied and its CONTENT can steer ffmpeg to open other
files or URLs (HLS/concat playlists). Pins -protocol_whitelist file,pipe and
-format_whitelist to the containers real recordings use, before the input
(after -i it would apply to the output).
Verified with the real static ffmpeg 7.0.2 on koala: real AAC .m4a and WAV
still probe/convert; a crafted concat file is rejected with 'Format not on
whitelist'. Note ffmpeg 7.0.2 ALREADY refused the playlists tried without the
whitelist, so the live check cannot prove the whitelist -- the argv unit tests
do; this protects against a different ffmpeg version being put in the image.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
A file's CONTENT can tell ffmpeg to open other paths or URLs (HLS, concat
playlists). ffmpeg 7.0.2 refuses the ones tried, but that is version luck and
the image's ffmpeg is still to be chosen (#34). Pin protocol_whitelist to
file,pipe and format_whitelist to the demuxers real audio uses, before the input.
Red: audio.AllowedDemuxers is undefined.

The proposed 120,000-char budget was a guess; measured, gemma4-26b silently
loses the head at that size and phi4-mini (first in the offered list) 400s on
an hour of speech. Budget is now 90,000, uploads open on gemma4-26b, the
retrieval trigger is concrete, and the iguana contention hazard is recorded.
ADR-033 is still Proposed, so this is an in-place correction, not a supersession.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
phi4-mini 400s at ~13k tokens; gemma4-26b is correct to 90,000 chars and
silently loses the HEAD at 120,000 (no error, no truncation flag). The
end-needle test alone passed at 120k -- only a head-needle exposed it.
Records the default-model trap and the iguana contention hazard.

cmdServe assigned Uploads and UploadLimits but not UploadChatMaxChars, so chat
over a long recording would have used the 18,000-char caption default. It now
calls wireUploads, which is tested.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
I wired Uploads and UploadLimits in cmdServe but not UploadChatMaxChars: chat
over a long recording would have silently used the 18,000-char caption
default. A helper that main and the e2e test both call makes that a tested fact.
Red: wireUploads is undefined.

The Chatter's own default is the summarizer's (koala/phi4-mini, 8,192-token
context), which answers HTTP 400 on an hour of speech. Empty keeps the old
behaviour.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
iguana/gemma4-26b answered correctly at 90,000 chars but SILENTLY dropped the
head of a 120,000-char transcript (prompt tokens fell to 16k; 'not in the
text'); koala/phi4-mini has an 8,192-token context and answers HTTP 400 at
~13k tokens. So the budget is 90,000 and the upload chat model defaults to
gemma4-26b. Red: UploadChatModel is undefined.

The 'no audio-download + STT' bullet is narrowed to YouTube (ADR-007 stands);
adds the upload packages, the exact-set isolation test and the pending ffmpeg
decision to the build state.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Adds the private uploaded_transcripts entity and the exact-set isolation rule
(ADR-033). Also corrects two lists that still named `transcripts` as an RLS'd
table: it has been shared non-RLS since ADR-021 / migration 015, and these
lists sit next to the very boundary that matters.

Real ffprobe/ffmpeg, the live gateway and a real chat model, a private
embedded Postgres. Skipped unless TAPIR_E2E_AUDIO is set. Run 2026-10-01 with
82 s of synthetic Swedish as AAC .m4a:
- primary: iguana/kb-whisper, 82.6 s audio, 1,186 chars; asked who owns the
timber order, the answer named Anders and the 15 November deadline from the
transcript; the spool directory was empty afterwards.
- primary forced to fail (TAPIR_TRANSCRIBE_MODEL=iguana/does-not-exist): the
fallback served it and the row recorded endpoint=berget/kb-whisper.
Synthetic audio only; this repo is public.

GET/POST /uploads/{id}/chat, mounted only when both an Uploader and a Chatter
are wired. The row comes from the user-scoped private store, so another user's
upload is a 404 before any model is involved. The owner's transcript goes to
the SAME Chatter with App.UploadChatMaxChars instead of the 18,000-char caption
default. The chat panel is shared, not forked: chatView gains PostURL/Subject
(empty = a YouTube video, so existing callers are unchanged). The done card
links to chat only when chat is wired.
Mutation-checked: dropping the upload budget, ignoring the done-status guard,
or scoping the lookup to the wrong user each turn tests red.

templ escapes the apostrophe in "couldn't", so the assertion could never match
the rendered page. A test defect, not a loosening: the failure must still be
shown inline with the conversation kept.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Owner sees the panel posting to /uploads/{id}/chat; an unfinished upload
redirects to its status; ANOTHER USER'S upload is 404 on GET and POST and no
model is ever called with it; the owner's transcript is sent with the upload
budget (not the 18,000-char caption default); an unoffered model falls back; a
model failure is inline and keeps the conversation; routes are absent without a
chat backend; the done card links to chat only when chat is wired.
Red: App.UploadChatMaxChars is undefined.
