The Database connections panel drew idle connections as their own line, which
sits on the max for ten minutes after any burst and read as the pool maxing out,
while at most two were ever in use. It now draws in use against the max, with
open dashed behind them. The pool itself goes from sqlx's ten to twenty: the
server allows 100 and had about 13 open across every app.

Kept bytes against the limit was a flat line once the cache filled. Now a
percentage of the limit beside the share served from disk, and the images each
sweep evicts. The counter shipped minutes ago as ipx_art_trimmed_total is
renamed ipx_art_evicted_total before anything came to read it.

The sweep trims the cache to its limit, so the kept bytes it reports are the
limit every time once the cache has filled: the panel was two lines flat at
500 MiB. A counter of images thrown out says whether the limit is too small.

The clean-up of DeadAir's old copies probed for its table on every open, and on
Postgres each failed probe is an ERROR in the server's log: 120 an hour from the
healthcheck alone. Production ran it already and is the only database.
A scan sent a not-due skip for each of ~1,535 feeds into a broadcast of 1,024,
so a page slow to read lagged and dropped events: 443 counted in five hours.
Nothing listening uses them; the terminal and the log still get them.

A seventh check groups the browser's errors and lists play starts and
stalls (ipx::client, #190); the trace check names the steps of an item
list, the feed list, a reap and DeadAir's per-file trace (#187), and says
a trace with no name began in the page (#192), which query.py now labels;
the events list has deadair_done and DeadAir's own lines; and "since the
last deploy" is worked out from the container's start.

The healthcheck answers while the worker is stuck on one job, and nothing
showed which job or for how long. STATS, one static of atomics, is kept as
the work happens: the worker's job and since when (a guard, so a failed or
stopped job is counted too), jobs and their seconds by kind, when a scan
last finished, web requests, feed fetches and downloads in progress, bytes
downloaded, live updates dropped for a listener that fell behind, DeadAir's
backlog and how long it has been on its file, and the artwork kept. With
the event queue, the DNS retries and the healthcheck's last counts, /metrics
still reads memory only. The dashboard's Daemon row and the prod-check
skill take them up.

query.py prom asks Prometheus as it asks Loki, and a sixth check looks for
a pool at its max, a worker or runtime queue that only grows, memory, open
files or tasks that only climb, and restarts by the uptime's resets.

/metrics shared the web server's threads, and answered after a token
lookup and three counting queries, so a pool run dry, one of the things it
is there to show, would have stalled it, and a slow scrape held a web
thread. Now [web] metrics_bind starts a listener on its own OS thread with
a current-thread runtime, reading only what is in memory: pool counts,
channel capacity, the daemon runtime's metrics through its handle, /proc.
No sign-in, as exporters have none; publish the port to the LAN only. The
feed, pending and downloaded counts stay with the healthcheck's log lines,
which the dashboard already reads.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Logs and traces show requests, scans and downloads; nothing showed what
the daemon holds meanwhile. /metrics, behind sign-in, gives database
connections in use and idle against the pool's maximum, commands waiting
for the worker, live-update listeners, free torrent slots, episodes
playing through DeadAir, the library's counts, the tokio runtime's
workers, tasks and queue, and the process's memory and open files, in
Prometheus's text format, written by hand rather than with a client
library. Not logged or traced: Prometheus asks every 15 s. The iPX
dashboard gains a Daemon row of them.

stale_unsubscribed takes the newest item of every unsubscribed feed, 2-5 s
warm and up to 12 s in production, and reap ran it before each scan, every
few minutes, holding up the sequential worker's scans and downloads. Its
thresholds are a month dead and a year quiet, so a day is plenty. Kept in
memory: a restart looks again at once.

hls.js sends traceparent on its own requests (xhrSetup); a beacon, which

All Subscriptions took 130-170 ms when used a minute before, and 0.5-1.9 s
the first time after a quiet spell. Its sort needs each item's date, which
was only in the item's row, so every one of a person's 13,700 rows was
read, show notes inline and all, and cold that came off disk; count_in,
which needs no date, took 20 ms throughout. entries_by_time holds the keys
and dates, the page's keys are sorted and cut from it, and only the rows
shown are read. On a copy of the shape in the test database: 619 pages
read against 4,174, with no visit to the table. Neither change alone
helped.

Following the rule CLAUDE.md now gives for cutting a release: a feature
added and reworked in one release is one line saying what it became, and a
fix for a bug no release had is gone. 0.11.0's DeadAir fixes join DeadAir,
0.9.1's JSON log, website icons, adding a website and logo are one line
each, 0.10.0's Directory, sort and Popular one, 0.4.0's toolbar, item table
and icons fold together, and 0.2.0 and 0.3.0 lose the fixes to the web UI
and accounts they introduced. The [unreleased] link compares from v0.11.0.

Nothing the page did in the browser reached the logs: a DeadAir playback
failure on the phone was a toast and nothing more. POST /api/client takes
page errors, unhandled rejections, hls.js and media errors, the time from
play to sound and the length of a stall, and logs them as ev lines under
ipx::client, inside the request's span. Only those kinds are taken, the
text cut to 500 characters, and the page sends each at most once a minute.
The page's API requests send traceparent, a new trace id for each tap or
key, and the server's request span takes it as its parent, so one action's
requests are one trace in Tempo, the report included. The stub DOM the
smoke and native-bridge tests run in gains crypto and performance, which
every browser the page runs in has.

Played from ipodderx.sdf1.net, DeadAir's audio reached ipx as one request
with no Range header: Cloudflare caches by extension, deadair.mp3 has one,
and /media said nothing about caching, so Cloudflare fetched the whole file
and served ranges from its own copy, to anyone Access let in, without the
subscriber check (#129). /media/{id} has no extension and was never cached.
Cache-Control: private on every media response, the save included.

A 47 s reap had a trace of one span, so whether the time went on checking
every file on disk, the database or deleting could not be told. The reap's
steps are spans now, with what it removed on the reap span; an episode
list's query, sanitising, DeadAir and count are steps; and DeadAir's work
on a file is a trace of its own (probe, silencedetect, frame_bytes,
store_plans), only for files it looks at, not the idle passes.

Each touch event was awaited before the next went, so on a busy machine a
drag's ten messages took longer than the 800 ms a swipe has, and the page
took it for a slow drag. Reproduced by spacing the messages 110 ms apart:
the swipe back stayed on Second Episode, as the failing run did. The page
is right to want a swipe quick; a finger does it in well under that.

The save button fetched the original while the player played it shortened.
/media/{id}/deadair sends the original's ID3 tag and then the pieces of the
person's plan one after another, read as it goes: MP3 and ADTS frames each
stand alone, so that is a file any player takes, and nothing is stored, as
with the playlist. The tag stops at the first kept frame, since what can
follow it, the Xing frame, gives the original's length.

Below the box it read as a setting about something else. It sits after
the download options' fold, not in it, since DeadAir applies whether or

"Pause it leaves" said how DeadAir works, with an "it" to decode, not

The four segmented buttons gave no sense that 0.2 to 0.5 s is one scale,
and stayed on screen with DeadAir off, where they did nothing. A range
input with a dot at each stop and Brisk/Relaxed at its ends says both.

DeadAir made a shortened copy of each episode with ffmpeg: as much disk
again as the original, one pause length for everyone, and a minutes-long
wait after the download. Seeking past silences instead was tried on an
iPhone and left about 1.3 s of nothing at every cut (#178).
Now it finds a file's silences once (silencedetect, plus ffprobe for
each frame's byte position) and stores a plan for each pause a person
can choose, 0.2 to 0.5 s: the cuts, and the frames kept as byte ranges
of the original. /media/{id}/deadair.m3u8 hands this person's plan out
as an HLS playlist of ranges of /media/{id}/deadair.mp3, the original.
Tested on iOS Safari first (#180): no gap at the cuts, plays locked,
seeks exactly, and needs no ID3 timestamp in front of each piece.
Other browsers get hls.js (1.6.19, the light build), loaded only when
needed. Not where canPlayType says it can play HLS: Chromium answers
"maybe" and then fails on MP3 ranges with "stream parsing failed", so
only Apple's browsers play the playlist themselves.
The pause is per person and per show, on deadair_prefs.pause_ms, 0.3 s
unless chosen; 0.2 s, what the copies left, made speech sound rushed.
AAC in MP4 has no ranges a playlist can use, so only MP3 and ADTS AAC
are shortened (the library is 803 MP3s and no .m4a). The copies, their
table and #179's expiry go: the first start drops the table and deletes
the files it names, only those named name.deadair.*.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A copy is nearly the size of its original and was kept as long as the
original. Now `deadair.played_at` notes when one was last served (at
most once an hour, since a player asks again at every seek), and each
pass of the maker removes copies unplayed, or unmade, for 7 days. Only
the file goes: the row keeps its cuts with its path cleared, which
tells an expired copy apart from a file that cannot have one (no cuts)
and keeps the background queue from making it again straight away.
Serving the original of such an episode deletes the row, which puts it
back on the queue; the copy then comes back within a pass, though the
page does not switch to it mid-play (#178).

Bookworm's ffmpeg is 5.1.9, two major versions behind, and DeadAir runs
everything through it. Both stages move, since the binary built in the
first has to find the same glibc in the second.
Checked in the new image on techpod-358 with a 643-term drop expression,
the size that failed with a bsf_list error on 5.1 today: the copy is
352.73s shorter, as 643 cuts of 21 frames at 26.122ms predict, and
decodes without errors.

A new download in a show with DeadAir on plays at full length until its
copy is made, and nothing said so. Each file now carries
deadair_pending while DeadAir is on for its show and the copy is still
to come (not for one heard through, which it passes over), and the
episode's line and details say "Cutting dead air…". The maker sends a
deadair_done event when it finishes a file, and the page takes the list
again, so the line becomes how much shorter the episode is without a
reload.

The pane is 245 px wide above 820 px, and a downloaded file's size and
four buttons did not fit, so delete wrapped under the rest. The row no
longer wraps, its gaps and the buttons' padding are tighter, and the
size gives way with an ellipsis if anything still has to.

Production's ffmpeg, Debian's 5.1, refused the copy of Brad & Will's
359: "Error initializing bitstream filter: bsf_list". The frames to drop
went to it as between(...)+between(...)+..., which nests a level a term,
and 5.1 takes 100 terms and refuses 200; the 6.1 the tests ran on took
all 520. Summed as a balanced tree the same 520 nest about 10 deep, and
5.1 takes 4000 that way, checked in the production container.
The failure was also stored as the file having no copy, so nothing would
have tried it again after this fix. Failures are now remembered until
the next start instead. The cap on cuts drops to 3500, so the argument
stays under Linux's 128 KiB with frame numbers in the millions.

The copy maker skips an episode everyone who would hear the copy has
finished, and took finished to be the read mark. Opening an item sets it
as well, so 359: Potatoes From the Sky, opened and downloaded with
DeadAir on for its show, got no copy. Finished is now a place at 90% of
the length or past it, as Currently Listening has it.

The switch, the button's tooltip, the toasts and the time saved now say
what the name already pictures, the dead air cut, instead of explaining
it as silences shortened each time. The caption says the voice keeps its
own pace, which is the part people doubt, and names the shows to leave
out: stories whose pauses are part of the telling.

A DeadAir switch in each show's settings, and the same switch beside
the speed for the show that is playing, drawn as a waveform with its gap
closed up, outlined when off and solid when on, with aria-pressed. A
file the server gives a copy for plays from /media/{id}/deadair. An
episode's line says how much shorter it is, and Settings says how much
DeadAir has saved you.
Turning it on or off mid-episode saves the place with a request it waits
for, not a beacon, then asks for the entry again from the new
GET /api/entries/{feed}/{guid}, whose position is in the clock of the
version it now plays, and carries on there. A copy not made yet plays
from the next time. Turning a show on wakes the copy maker, so the copy
is there in seconds rather than at its next pass.
The browser test plays a real MP3 with long silences, quiet.mp3, from a
show it adds and removes itself.

There was one switch for everything, with a feed kept out by hand; any
feed already subscribed would have been in it the moment the switch was
turned on. Now each feed, or the group it came in, is turned on by
itself, and a feed of a group turned on can still be kept out. The
general switch and /api/me's deadair are gone; /api/me keeps
deadair_saved.

For anyone who turns DeadAir on, a background task makes each episode a
copy with every silence quieter than -38 dB for over 0.35 s shortened to
0.2 s. Nothing is re-encoded: ffmpeg copies the original's frames and
leaves the silent ones out, about 11 s for an hour of MP3 in a release
build. On Brad & Will's episode 359 that is 520 cuts and 3.3 minutes
saved, the copy decodes clean, and it has no isolated spikes in its
silences that the original lacks.
Cuts are made from the middle of each silence, keeping 0.1 s at each
end, so the frames either side of a cut are silent: decoding blends a
frame with the one before it, and an MP3 frame can begin in the bytes of
the frame before, so the first frame after a cut decodes against the
wrong neighbour. Inside a silence nobody hears that; at a word they would.
Positions stay in the original's time and the server converts them both
ways. The iOS and Android apps save positions themselves from their own
player, even while the page is asleep, so converting in the page would
have stored the copy's times as the original's. /media/{id}/deadair
serves the copy at its own address and records that this person is
playing it; a position saved meanwhile is converted from the copy's
clock, as is the length a player measures.
The copy is made by a task of its own, not the worker: a first pass over
a library is hours of ffmpeg, and scans must not wait behind it. It
checks every two minutes, which covers new downloads, files already
downloaded, a switch turned on and a file downloaded again with one rule.
Episodes everyone who would hear the copy has finished get none.
download::remove deletes a copy with its original, and the quota counts
copies.
Settings: the switch is PATCH /api/me {deadair}, a feed kept out is
PATCH /api/feeds/{id} {deadair: false}. GET /api/me gives the switch and
deadair_saved, the seconds saved on episodes heard 75% or more on a copy,
each counted once. Three new tables, so no ALTER.
The image gains Debian's ffmpeg, about 480 MB, in a layer that stays
cached until the base image changes. The player's switch, the feed
setting and the stat come next, after mockups.

Five Glass Cannon Network feeds name Patreon covers of about 7 MB, over the

Directory category) held what a person reading the feed cannot and should not change. The address

can still follow a feed that moved from its failing banner. The folder and the category leave the

One column of label, box and grey paragraph, eight times at the same weight, three screens long on a
phone with Save at the bottom of the third. Approved from the mockups on #167.
- Download automatically comes first, as a switch; how many, the keywords and explicit, which only
ever applied to automatic downloads, hang beneath it and fold away when it is off.
- How many is Default, Newest or All, said as a sentence with the number in it, over a strip of the
feed's own newest items, each as tall as it is long and lit where it downloads; dragging along
it sets Newest. All is 0, which now means all (#166).
- Keywords and hidden words are chips: Enter or a comma adds one, its x or Backspace removes it.
- The feed's own settings, the same for everyone and an admin's to change, sit apart in a box.
- The body scrolls and Cancel and Save stay at the foot.
- Theme colours only; iOS switches, but checkboxes in Classic. openModal takes a class for a
dialog with a frame of its own, set whole each time so it never outlives it.
A browser test covers the strip, chips, the fold and a save that holds.

All Subscriptions said 1 unread when the server had none. The badge is the page's own sum of its
feed list, loaded once and patched only by events the server sends when a scan or a download
changes a feed. Reading an item, marking everything read or unsubscribing sends none, so another
device's page kept its old counts, and an iPhone stops the event stream while the app is in the
background, missing everything meanwhile; the reconnect did not catch up.
The page now takes the feed list and the open list again when it comes back into view and when the
stream reconnects after a drop. A browser test reads an item behind the page's back and checks the
badge follows once the page is shown again; it fails without this.
