Spotify's CloudFront serves some covers as application/octet-stream and
pippa.io sends no Content-Type at all; both are JPEGs, which browsers sniff
and show, but /api/art refused them with a 502 and the podcast showed its
initials. An untyped or octet-stream answer is now read and checked for
JPEG, PNG, GIF or WebP magic; anything else, SVG included, is still refused.

With the server paying for everyone's Signals, its bill had no names.
ipx_signals_judged_total, ipx_signals_hits_total and ipx_jev_tokens_total
now carry user (the account's name) and key (server or own); a call
shared on the server's key is split by each person's share of its
questions. Icon picks bill the person on the server's key, key checks on
their own. The dashboard has tokens and items by person and a Who used
what table over its range.

TypeSafe allows 80 requests and 100,000 input tokens a second. Six calls
in flight was a cap on concurrency, not rate: at 74 ms a call it is 81 a
second. Every call to Jev now takes a turn, a 60th of a second or its
guessed tokens' share of 80,000, so up to ten can be in flight. A 429
holds every call back for Retry-After and ends the pass. Each jev span
records paced_ms, /metrics ipx_jev_paced_seconds_total and a rate_limited
result, and the dashboard draws calls and tokens a second against the
limit.

Deployed, the judge's query still read every entry: an expression index
has no statistics until its table is analysed, and Postgres, guessing a
third of entries were recent, chose a scan (898 ms) over entries_recent.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The judge's query read all of entries (605 MB, 566 ms) on every wake; an
index on each feed's items by date, as the query asks, and the rechecks
in a half of their own. Calls ran one at a time, about 150 ms each, so a
new Signal's month of about 8,000 items took twenty minutes: six in flight
now. On the server's key everyone's Signals on an item share one call.
TypeSafe's token counts go to /metrics and each jev span.
An item's text is cut at 1,000 characters instead of 2,000: on 55 real
items of eight podcast feeds and six Signals, on the development key,
1,000 changed none of 330 verdicts (nor did the same request twice) and
saved 12% of the input tokens, 1,266 to 1,112 a call; 500 changed one.

docs/signals.md says what the admin's setting does and that a key is
checked before it is saved; the install guide lists TYPESAFE_KEY; the API
reference has Signals' routes and types and the new fields of Me and
Settings; the home page says an admin may provide the key.

/src/.envrc's TYPESAFE_KEY is a development key, so the test daemon uses it
and the server paying for Signals is tested end to end. Signals' tests spend
it, so each runs only when the Signals code or the test itself has changed
since it last passed (a hash kept under target/signals-tests);
IPX_SIGNALS_TESTS=1 runs them anyway.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
With signals_on_server set and TYPESAFE_KEY present, the judge asks Jev
about everyone's Signals on the server's key; otherwise each person turns
Signals on in Settings with a key of their own, which is now checked with
TypeSafe before it is saved. The Signals folder shows only when they are on.
The browser suite's daemon inherited the shell's TYPESAFE_KEY, so fixture
feeds were sent to the real TypeSafe to be categorised; it is blanked now,
and an empty key counts as none.

The judge had spans but nothing in Prometheus: no count of items judged or
of how calls to Jev ended, nor whether the judge was still passing. The jev
span recorded an error field without the span's status, so Tempo's failed
traces left Jev out, and a timeout recorded nothing. Calls now send
traceparent like every other call out of ipx.

The drawn list's made-up titles read badly. The screenshot is a Signal

Signals (#254) in ipx and the page, and the compression and tracing
work of #239-#253 in all three.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Neither orange tile nor orange icon on the tint worked, so each
Signal's tile is back in the theme's accent tint, as it was before
#268. The Signals folder icon and the larger DeadAir tile stay. The
tile rules go above the initials' comment, which they had split from
its rule.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A solid orange tile was too loud. Each Signal's tile is the folder's
accent tint again, and its icon or initials are drawn in the orange of
the Signals icon's point: #ff6a1a in dark. In light it is the light
palette's needle, #c43e00, since signals.svg's #ff5500 on the tint is
about 2:1, too faint for initials (about 3.4:1 instead).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
--accent2 mixed a quarter into the ground came out salmon, and is pink
or blue in other themes. Each Signal's tile is now solid #ff6a1a, or
#ff5500 in light, the point of signals.svg and signals-dark.svg, in
every theme as the icon is, with the icon or initials in the logo's
navy (#0c2238, 5:1 or better on either).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Each Signal's tile, icon or initials, is tinted --accent2 in place of
--accent: the orange point of the Signals folder's own icon, so the
folder and what is in it read as one. The player's DeadAir tile goes
from 22px to 26px in its 30px button.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
web/signals.svg and web/deadair-{on,off}.svg, each with a -dark twin,
follow logo.svg's rules: square and opaque, the logo's gradient ground,
flat layers in its scale blues, the needle's orange, nothing thin
enough to vanish at 32px. Signals is the page's own glyph, waves going
out from a point, the point in orange. DeadAir on is the waveform
closed up with the needle at the cut; off has the silence still in its
middle, an orange flat line, and its bars muted, so the state is in
the shape as the old glyphs had it.
The Signals folder row and its page header show the Signals tile in
place of the glyph on an accent tint; the player's DeadAir switch shows
the on or off tile. tile() puts both variants on the page, and the mode
rule that picked the logo's now picks any .onlight/.ondark. The three
glyphs nothing uses any more are gone.

xkcd's posts are an <img> whose alt and title are the comic's words. text_of dropped tags whole,
attributes and all, so Jev was sent "Feed: xkcd.com / Title: Ground Effect", ground effect being
an F1 aerodynamics term, and the comic went into the Formula 1 Signal at 0.60. With the alt text
it scores 0.19. Alt and title are read once each, and once when they say the same.

Font Awesome's Mandalorian icon has "disney plus" among its search terms, the only icon with
"disney" in them, so a search for Disney Parks' words offered it and Jev picked a Star Wars helmet.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Jev chooses among options and cannot name one, so the page searches Font Awesome's index for each
word of the Signal's name, words and sentence, the best six each, and offers the likeliest 40.
POST /api/signals/icon asks a choice question on the server's TYPESAFE_KEY and answers with one
of those offered, never another. "Let Jev pick" in the icon picker, and a Signal made without an
icon gets one a moment after. Tried against TypeSafe: for AI Development, laptop-code 0.45 just
ahead of robot 0.40.
Each Signal's row says "12 items · 3 unread", as a feed's row counts its own, in place of its
words; /api/signals gives `items` beside `unread`, by the same rules as its list.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
unjudged() limits rows, one for each item and Signal, to 50, and the pass took the queue for
empty whenever the items numbered fewer than 50. With two Signals every batch is 25 items, so the
re-judge after #259 crawled at 25 items every 5 minutes. A batch is now full by its rows. A pass
TypeSafe stopped as malformed waits for the next wake however full it was, rather than asking again
at once.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Jev was asked "Is this item about any of these: ai, development, programming?", so any one broad
word was enough and the Signal's name, which says what is meant, was never sent. AI Development
held 54 items: Sega pulling a game remaster (0.90), a Surface Laptop review (0.95), a C++ tutorial
(0.99). It is now asked about one subject, called by the Signal's name, described by its words
and, when those are not enough, its owner's sentence. Scored against TypeSafe over those 54 with
"AI tools for writing software: coding agents, AI dev tools, vibe coding, AI in code review.":
5 stay, Linux kernel AI code review highest at 0.94; the remaster 0.06, the C++ tutorial 0.02.
signals.description is new, and its first start deletes every verdict, which answered the old
question, so everything in the window is asked again. Any change to a Signal's name, words or
sentence drops its verdicts, since each is part of the question. The queue query names the
Signal's sentence apart from the item's description, which share a row; the test caught the
item's winning.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The page fetched the Signals' unread counts only with the feed list, so reading an item, here or
in its own feed, left its Signal's badge as it was, and so did Jev adding one. The Apple Signal said
2 unread over a page with none. The page now fetches them again after a read or unread lands, and
on a new signal_hits event, which the judge sends once a pass for each person it found items for.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Every call was refused with 422: a noul question's `criteria` is an object of what true and false
mean, and it was sent a sentence. The error kept only the status, from error_for_status, so the log
and the trace said 422 and not why; TypeSafe's body said "Input should be a valid dictionary"
at questions.3.noul.criteria. The body is now in the error and on the jev span, with the status.
A request refused as malformed (400, 422) ends the pass, since every other item's would be refused
the same way: the 50 warnings a pass were the same failure 50 times. The state is text now, as
TypeSafe's docs show it, rather than an object that sent null for a feed with no title, and the
questions are keyed signal_<id>. Checked against TypeSafe with the corrected request: 0.96 for an
item about the keywords, 0.02 for one that was not.

The dialog asks what to listen for, the page says what it picked out of the noise of your feeds,
and a new Signal says nothing has come through yet instead of showing an empty list.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A Signal is a name and keywords. A task beside DeadAir's asks TypeSafe's Jev, on the owner's own
key, about each item of their subscribed feeds from the last 30 days and every new one: one call
an item, one noul question for each of their Signals still to hear about it, 0.5 or more a fit.
Every verdict is kept, fitting or not, in signal_verdicts, so nothing is asked twice, and new
keywords drop a Signal's verdicts to be judged afresh. A key TypeSafe refuses (401/402/403) is
passed over until its owner saves another, so a bad key is not sent the whole queue.
A Signal's items come through entries_where with an EXISTS on its hits, so filters, search, sort
and read state are an ordinary list's, and reading an item in a Signal reads it in its feed.
The page shows Signals under the places, with New signal, and Settings takes the TypeSafe key,
which is never sent back. The browser suite stubs Jev in the fixture server (IPX_TYPESAFE_URL).

Set 2026-10-16 in Admin, Directory, where it was https://directory.ipxreader.app: every Directory
page and snapshot went out through Cloudflare and back down the tunnel, 170-340 ms a call, and a
Directory page took 150-200 ms; 29-54 ms now.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Measured 2026-10-16, uncompressed until now: the directory's answers (the feed list ipx reads,
603 KB of JSON, ~134 ms of a 159 ms Directory request), ipx's snapshot upload (~100 KB each half
hour), both /metrics (4.7 and 0.9 KB every 15 s) and every trace export to Tempo. Already
compressed: ipx-web's answers (zstd, #239), the home page and the directory's public pages
through Cloudflare (brotli, zstd).
- The directory compresses with brotli, zstd or gzip as asked, and unpacks a gzipped request.
- ipx sends its snapshot gzipped; the directory is deployed first.
- Both /metrics answer gzipped, as Prometheus asks.
- opentelemetry-otlp's gzip-http: OTEL_EXPORTER_OTLP_COMPRESSION=gzip compresses the export, set
for all three in production's compose file; Caddy's exporter reads the same variable.
- web/build.mjs writes .br (quality 11) and .gz (level 9) beside each text file, and Caddy serves
them in place (file_server precompressed): app.js 30 KB where zstd on the fly gave 37, app.css
11 where 14. A .br or .gz asked for by name is refused, or /admin.js.br would be the admin
page's script without the check that keeps it to admins; in a handle of its own, since a bare
respond runs after the handles.

A Directory page took 983 ms during a scan with 19 ms under spans: the directory's own span ends
when it has answered, and ipx's reading of the 458 KB answer, its subscriptions and catalogue,
and the matching of 1,471 listings had none. call() is a span now, directory_call, with the
answer's size; rows_for has subscriptions, catalogue and match steps.

With apple_country set, the directory fetches Apple's top 100 podcasts and the top 50 of each of
its 19 categories for that country (itunes.apple.com/{cc}/rss/toppodcasts), looks up each
show's RSS address (/lookup, 100 ids a call, three seconds apart, as Apple asks for no more than
about twenty a minute), and stores them as the snapshot apple-podcasts with no subscribers. The
refresher fetches them like any feed; the most-subscribed chart is unchanged. Apple's primary
genre goes in as the snapshot's category, used only while a feed names none.
The same weekly run reads Apple's genre tree (ws/genres?id=26) and warns when it differs from
ipx_feed's CATEGORIES; on 2026-10-15 they were the same, all 19 and their subcategories.
A syncs table keeps when it last ran: at start if a week has passed, again weekly, an hour after
a failure. keep_instances spares apple-podcasts, which no token holds, and no token may take
the name. A trace a sync, a span each answer.
