Readings in the requested order; 1/2 mapped to base/alt under both orders;
UNSURE, an unparseable or out-of-range reply is unsure rather than a guess; an
empty reading is described, not blank; a model error is an error, distinguishable
from 'unsure'. The optional order-checked wrapper asks twice with the order swapped
and keeps only agreement.
Red: Request, Verdict, NewLLMAdjudicator and NewOrderChecked are undefined.

Disputes carry both readings with their own spelling; differences separated by
one shared word merge into one decision. Compound splits/joins and one or two
filler particles are resolved without a model; 'nej', numbers and content words
never are. Mutation-checked (merge distance, filler limit, 'nej', compound rule).

A dispute carries both readings with their own spelling; differences separated by
a single shared word are one decision, two shared words keep them apart; compound
splits/joins and a short run of filler words are resolved without a model, while
numbers, content words, and 'nej' (an answer) are not.
Red: FindDisputes, AutoResolve and ContextAround are undefined.

Prefix/suffix trimmed first; adjacent deletes and inserts read as one Replace;
beyond 3,000 edits (two texts sharing almost nothing) the middle is one Replace
instead of gigabytes of trace. Mutation-checked: a wrong tie-break, missing
replace coalescing, wrong suffix accounting and a punctuation-bearing key each
turn tests red.

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.

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.

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.

Up and down are one commit: golang-migrate pairs them. RLS is unchanged: the

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.

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.

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 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.

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.

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.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
chat.Request.MaxChars overrides the Service cap when positive. The 18,000-char
default (~22 min of speech) suits captions; an uploaded hour is ~50,000 chars
and truncation keeps only the head. This is reuse of the existing chat path,
not a fork.

Embedded UploadConfig. Off by default until the image carries ffmpeg; 200 MB /

TAPIR_TRANSCRIBE_FALLBACK_MODEL disables (private audio then never leaves the
homelab); zero or negative limits fail at load instead of rejecting every
upload at runtime.

Queue -> StartTranscribing -> ffmpeg to 16 kHz WAV -> gateway chain ->
CompleteUpload, with a per-job timeout so a hung endpoint ends in failed, not
a spinner. The upload and the WAV are deleted on every path (audio is never
retained). A shutdown mid-job is not a failure: the row is left for the
start-up sweep. Cancellation wins over a non-empty queue, so queued jobs are
never started on shutdown; stop() deletes their audio and refuses new jobs.
Concurrency is 1 on purpose: two simultaneous long jobs on iguana were never
measured, and a Metal OOM there latches whisper (infra#273). The queue is
process-local, so ADR-018's single-replica assumption now has a second
dependent.
Mutation-checked, -race clean: cleanup, shutdown-vs-failure, timeout,
concurrency and stop-cleanup each turn a test red.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Mutation-testing the worker showed deleting stop()'s cleanup went unnoticed:
Process was incidentally deleting the audio of jobs it should never have
started. The stop test now asserts only the running job was converted (red on
the old code). The timeout test no longer hangs for the 10-minute go test
default when the timeout is removed.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Success path deletes both the upload and the WAV; failures are typed and still
delete the audio; a shutdown mid-job leaves the row for the start-up sweep
(it is not a transcription failure); a hung endpoint is failed by the job
timeout, never an eternal spinner; strictly one job at a time (two long jobs on
iguana were never measured); stopping deletes queued audio and refuses new jobs.
Red: uploads.Worker is undefined.

Replaces whisper-server --convert. A zero exit that wrote nothing is an error.
Also fixes the red test's stub, which wrote an empty file and so (correctly)
tripped the no-output check.
Checked against real ffmpeg on iguana with the same argv: AAC .m4a in,
pcm_s16le 16000 Hz mono WAV out, duration preserved.

The httptest fake proves only what we THINK the gateway accepts. Skipped
unless TAPIR_LIVE_WAV and TAPIR_LIVE_GATEWAY_URL are set. Run once on
2026-10-01 with 11 min of synthetic Swedish (21 MB, above the 8-10 MB ingress
cap, via the NodePort): both iguana/kb-whisper (52.8 s) and berget/kb-whisper
(35.4 s) accepted the streamed, computed-Content-Length body and returned
usable verbose_json. Synthetic audio only; this repo is public.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Streams the WAV from disk with a computed Content-Length (no buffering, no
chunking), posts verbose_json with field `file` and language=sv, clamps the
final segment to the audio duration, and treats an empty transcript as a
failure. The chain falls back on ANY primary error, records the serving
endpoint, and never falls back once the context is cancelled.
gateway.go and chain.go are one commit: the chain's tests use the gateway's
StatusError and ErrEmptyTranscript, so neither compiles alone.
Mutation-checked: field name, clamp, cancel-fallback, content length and the
recorded endpoint each turn a test red.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Gateway: field is `file`, no Expect header, a computed Content-Length (not
chunked, not buffered -- a 90 min WAV is ~170 MB), verbose_json normalised
with the last segment clamped to the audio duration, errors independent of
the body, an empty transcript is a failure. Chain: ANY primary failure falls
back and the row records the fallback endpoint; a cancelled job never falls
back to the cloud.
Red: package transcribe does not exist.

GET/POST /uploads, GET /uploads/{id}, GET /uploads/{id}/status, mounted only
when an Uploader is wired. The multipart body is streamed to Intake, never
buffered. Rejections are synchronous: 422 (video, too long, unreadable) or 413
with the user-facing message and no row. Another user's id is a 404 that does
not leak the title. Unfinished states poll; done/failed render without
hx-trigger so nothing polls forever (ADR-025). A done transcript names the
endpoint that served it.
handlers.go, uploads.go and the templ pair are one commit: the App fields and
Store methods are what make the handlers compile.
Mutation-checked: dropping the 413 mapping, the not-found mapping, or letting
a done card poll each turn a test red.

Two defects in my red tests, found when going green: body() drains the

Real Router + real Intake + real Postgres; only ffprobe and the worker are
faked. Covers: the form states the limits up front; accepted audio queues a
row and redirects; video / too-long / too-large are rejected synchronously
(422/422/413) with a message and NO row; a non-owner gets 404 without the
title leaking; unfinished states keep polling and terminal states stop (no
stuck spinner); a done transcript names the endpoint that served it.
Red: App.Uploads / App.UploadLimits are undefined.

Cover art is not video; non-zero exit is the file's fault (ErrUnreadable),
a missing binary / cancelled ctx / bad output is ours. WaitDelay bounds a
cancelled probe whose child holds the pipe open.
Checked against real ffprobe on iguana: JSON shape matches the fixtures and
/etc/hosts exits 1 with 'Invalid data found when processing input'. The unit
tests drive a stub process; ffprobe is not installed on koala.
