 Under them, Tower itself: `job="node"` (the node exporter: load, CPU, memory, disks). The Grafana
 dashboard `iPX` draws all of it in that order (`grafana/dashboard.py`). A trace without the
 production tag (`resource.deployment.environment.name="production"`, on all three) is a daemon run
 by hand, not production. Since #213 a request is one trace across the services it touched: a

-## The checks
+### What Prometheus carries
 The daemon's own state between requests, which no log line or trace holds (#194): ipx serves
 `/metrics` on `[web] metrics_bind` (production: `192.168.1.130:9187`, LAN only), on a thread and
 port of its own, from memory alone, and Prometheus scrapes it every 15 s as `job="ipx"`. Kept
 from 2026-10-11 15:15 UTC. All gauges:
 | metric | what |
 |---|---|
 | `ipx_db_connections{state="in_use"\|"idle"}`, `ipx_db_connections_max` | the database pool: in use reaching the max means requests and scans wait for a connection |
 | `ipx_worker_queue` | commands waiting for the sequential worker (scans, downloads, adds) |
 | `ipx_event_listeners` | open pages and socket clients on the live-update stream |
 | `ipx_torrent_slots_free` | of 2 |
 | `ipx_deadair_playing` | episodes being played through DeadAir's playlist |
 | `ipx_runtime_workers`, `ipx_runtime_tasks`, `ipx_runtime_queue` | tokio: threads, live tasks, tasks waiting for a thread |
 | `ipx_process_resident_bytes`, `ipx_process_open_fds` | memory and open files and sockets; mimalloc gives back what is freed, so memory follows use and a rise that never comes down is a leak (#224) |
 | `ipx_feed_fetches_total`, `ipx_feed_bytes_total` | counters: feeds fetched (304s included) and the bytes of their bodies, read whole, so what scans allocate |
 | `ipx_uptime_seconds`, `ipx_build_info{version}` | since the daemon started; what runs |
 | `ipx_worker_busy`, `ipx_worker_job_seconds{kind}` | the worker's job now (`scan`, `reap`, `download`, `status`, `reload`) and for how long; the healthcheck passes while it is stuck |
 | `ipx_jobs_total{kind}`, `ipx_job_seconds_total{kind}` | counters: jobs finished, and their seconds all told |
 | `ipx_last_scan_age_seconds` | since a scan last finished; absent until one has since starting |
 | `ipx_http_requests_in_flight`, `ipx_scan_feeds_fetching`, `ipx_downloads_active` | work in progress |
 | `ipx_download_bytes_total` | counter; `rate()` is the download speed |
 | `ipx_event_queue`, `ipx_events_missed_total` | live updates unread by some listener; counter of those dropped for one that fell behind |
 | `ipx_deadair_backlog`, `ipx_deadair_busy_seconds` | files of shows with DeadAir on not yet looked at (episodes everyone heard through stay counted); how long it has been on its file |
 | `ipx_feed_retries` | feeds waiting to retry a failed name lookup |
 | `ipx_art_cache_bytes`, `ipx_art_cache_limit_bytes` | artwork kept, as of the last sweep, and the most kept: kept sits at the limit by design |
 | `ipx_art_evicted_total`, `ipx_art_requests_total{result="hit"\|"miss"}` | counters: images the sweep threw out to stay under the limit, and artwork served from disk or fetched from the publisher; many evicted at every sweep with a falling hit rate means the limit is too small |
 | `directory_process_resident_bytes`, `directory_process_open_fds`, `directory_feed_fetches_total`, `directory_feed_bytes_total`, `directory_uptime_seconds`, `directory_build_info` | the directory's, `job="ipx-directory"`, from its `metrics_bind` (production `192.168.1.130:9188`, LAN only) |

   `up` 0 means Prometheus cannot reach the port: the container is down or `metrics_bind` is
   unset. The daemon keeps all 20 connections open on Postgres (#241), so `idle` is the pool's 20 less
   those in use; in use at 20, idle at 0, means something is waiting for one: find the slow requests or scan of that time in check 3 and 5. A worker queue that only
   grows means downloads are not keeping up, or the worker is stuck on one job. A runtime queue
   above 0 for more than a scrape or two means every thread is busy: something is blocking a
   thread or burning one. Memory, open files or tasks only climbing across a day with no restart
   is a leak (a file or socket not closed, a task never ending); a step after a deploy is not. A
   reset of the uptime is a restart: match it with a deploy, or it is a crash (check 4).
   The worker: one job over 30 minutes (`ipx_worker_job_seconds`), or a scan last finished over
   15 minutes ago, is the worker stuck, which the healthcheck does not notice; its trace and the
   log lines of that time say on what. A kind whose share of `ipx_job_seconds_total` jumps is
   where the worker's time went (reap was most of it until #193). Web requests in flight near
   the pool's max mean the pool is what they wait on. Live updates missed mean a page showed stale
   counts until reloaded. DeadAir over a minute on one file is a file ffmpeg chokes on.
 7. **What the page saw.** The browser's own errors and timings, which no server line shows.
   ```
   $Q metric 'sum by (ev, msg) (count_over_time({container="iPX"} |= "\"target\":\"ipx::client\"" | json | __error__="" | level="WARN" [$range]))' 7d
   $Q logs '{container="iPX"} |= "\"target\":\"ipx::client\"" | json | ev=~"play_start|stall" | line_format "{{.timestamp}} {{.user}} {{.ev}} {{.ms}}ms deadair={{.deadair}} {{.feed}}"' 24h
   $Q metric 'quantile_over_time(0.95, {container="iPX"} |= "\"ev\":\"list_shown\"" | json | __error__="" | unwrap ms [$range]) by (feed, filter)' 24h
   ```
   A `player_error` is playback that failed in front of someone: `hls.js: ...` is DeadAir's
   playlist (its trace has the playlist and audio requests), `media error 4` a file the browser
   cannot play. A `page_error` or `rejection` is a bug in the page; `src` and `line` point into
   the minified `app.js`, so match the message to `web/src`. A `list_shown` over 1000 ms is a list someone waited for: its trace says whether the API or the network held it. `play_start` over 2000 ms, or a
   `stall`, is worth a trace: was it the server, Cloudflare, or the network.
 `docker logs --since 10m iPX 2>&1 | tail -5` shows the newest lines when Loki is behind.
 ## ipx-web, the page
 Caddy logs one JSON line a request (#210), logger `http.log.access.log0`: Loki's `| json` gives
 `request_uri`, `request_method`, `request_remote_ip`, `status`, `duration` (seconds, not ms), `size`.
 The request's headers and a `?token=` are filtered out before it is written. Requests from
 `127.0.0.1` are local checks; leave them out. `/api` and `/media` pass on to ipx and
 are in ipx's own access log too, with ipx's time; Caddy's `duration` for them adds the hop.
 ```sh
-docker ps --filter name=iPX --format '{{.Status}}'
+W='{container="ipx-web"} |= "http.log.access" | json | __error__="" | request_remote_ip != "127.0.0.1"'

+names it (`dial tcp ...:8099: connect: connection refused`). The page itself (`/`, `/admin`)
 waits on `/api/page-check` before it is sent, so a slow page is usually a slow page-check: look it
 up in ipx's access log. 401 and 303 on `/` are people signed out being sent to `/login`, not a
 problem. Caddy's own notices at each start (no admin endpoint, no HTTPS or HTTP/3, its goodbye on
 SIGTERM) are by design and filtered out above.
 Each access line carries the request's `traceID` (`| json` gives `traceID`): give it to `$Q trace`
 to see where the time went, Caddy's span with ipx's inside it. A slow page with ipx's span short is
 Caddy or the network; a long one is ipx.
 ```sh
 $Q traces '{resource.service.name="ipx-web" && duration > 2s}'
 $Q traces '{resource.service.name="ipx-web" && status = error}'
 ```
 Who reaches it: `request_remote_ip` is `192.168.64.1` for the tunnel and anything else on Tower
 (Docker's gateway), `192.168.1.130` for Tower itself, a LAN address for the LAN. Caddy passes
 Cloudflare Access's headers on only from `192.168.64.1` (`TUNNEL_PEER`), and ipx trusts them only
 from Caddy, with a valid signed token. Testing sign-in from Tower proves nothing about the tunnel
 (#209): send it from a container on another network.
 ## ipx-directory
 It logs a line a request (`target` `ipx_directory::http`: `method`, `path`, `status`,
 `duration_ms`, `token`, the token's name and never the token), a line a snapshot (`message`
 `snapshot`: `instance`, `accepted`, `refused_private`, `refused_blocked`, `refused_invalid`), a
 line a refresher round (`feeds checked`: `checked`), a line a failed feed check (`feed check
 failed`: `feed`, the directory's id, and `error`), the admin's actions (`feed removed and
 blocked`, `feed unblocked`, `snapshot dropped`, each with `by`), and `config read again` when its
 token file changes. It has no metrics. Its traces (#213): a span a request (`http`), a child of
 ipx's when ipx called with a `traceparent`, and a trace a refresher round (`refresh`, `feeds`)
 with a `feed` span for each check. Its log lines carry no trace id; find the trace by time or by
 the feed.
 ```sh
 $Q traces '{resource.service.name="ipx-directory" && duration > 2s}'
 $Q traces '{resource.service.name="ipx-directory" && name="feed" && duration > 10s}'
 $Q traces '{resource.service.name="ipx" && name="directory_share"}'
 ```
 A slow Directory page in ipx is usually its `http` span in the directory: the trace says whether.
 A refresher round far over a minute is one publisher's feed holding it, the slow `feed` span.
 ```sh
 D='{container="ipx-directory"} | json | __error__=""'
 $Q metric "sum by (status, token) (count_over_time({container=\"ipx-directory\"} |= \"ipx_directory::http\" | json | __error__=\"\" [\$range]))"
 $Q metric "topk(5, max_over_time({container=\"ipx-directory\"} |= \"ipx_directory::http\" | json | __error__=\"\" | unwrap duration_ms [\$range]) by (path))"
 $Q logs "$D | level=~\"WARN|ERROR\""
 $Q logs "$D | message=\"snapshot\"" 7d
 $Q metric "sum(count_over_time($D | message=\"snapshot\" [\$range])) by (instance)"
 $Q metric "sum by (feed, error) (count_over_time($D | message=\"feed check failed\" [\$range]))" 7d
 $Q metric "sum(sum_over_time($D | message=\"feeds checked\" | unwrap checked [\$range]))" 24h
 ```
 Expect a snapshot from each server when what it shares changes and every half hour, so about 48 a
 day each; one every half minute is ipx resending what has not changed (#211, fixed). A burst of
 401s with an empty `token` is someone without a token trying the public address, expected now and
 then; a steady stream is worth an issue, since Cloudflare can rate-limit it. A snapshot whose
 `refused_private` is not 0 means an ipx server tried to send a feed that looks private: find which
 in that server's log, since the directory refuses it but the sender should not have sent it. Many
 `feed check failed` lines for one feed are the publisher's, not the directory's. Each feed is
 checked every twelve hours (#243), 25 at a time, so `feeds checked` over a day should be about
 twice the feeds listed; none for over twelve hours means the refresher is stuck. `could not store a feed
 check` or `could not read which feeds are due` is its database (`ipx_directory` on the
 `databases` project's Postgres). A config that does not load (`config changed but does not
 load`) keeps the old tokens: worth fixing before someone's new token is needed. Weekly, `Apple
 Podcasts synced` (`shows`, `accepted`) brings Apple's charts in as the `apple-podcasts` snapshot
 (#252); `Apple Podcasts' sync failed` retries in an hour, worth an issue when it keeps failing, and
 `Apple's podcast categories are not ipx's` (`added`, `gone`) is an issue to update `CATEGORIES` in
 `crates/feed`.
 ## Tower
 The three share Tower with everything else, so a slow or failing ipx can be the host. The node
 exporter (`job="node"`) has the history; twelve threads.
 ```sh
 $Q prom 'max_over_time(node_load1{job="node"}[$range])' 24h
 $Q prom 'min_over_time(node_memory_MemAvailable_bytes{job="node"}[$range]) / 1e9' 24h
 $Q prom 'sum by (mode) (rate(node_cpu_seconds_total{job="node", mode=~"user|system|iowait"}[$range]))' 1h
 $Q prom 'max by (device) (rate(node_disk_io_time_seconds_total{job="node", device=~"nvme.*|md.*"}[$range]))' 1h
 ```
 For when, step back with `offset`: `max_over_time(node_load1[10m] offset 60m)`. Load far above
 twelve with little CPU busy is processes waiting, on a disk or on the user shares: on 2026-10-12
 debug builds linking through `/mnt/user` (shfs, FUSE) took load to 248 with mostly system time and
 stalled everything on the shares, ipx's downloads included. Available memory near nothing makes
 it worse. Disk busy near 100% on `nvme1n1` is `/mnt/fast`, appdata and Postgres's data; on `md*`
 the array behind `/mnt/user`, the downloads. Say what was running at the time if you can tell
 (`docker stats --no-stream`); a host problem is the user's, not an ipx issue, unless ipx caused it.
 ## The monitoring itself
 A quiet dashboard can be a dead exporter. Check what Prometheus scrapes and that each
 container's lines are reaching Loki:
 ```sh
 curl -s http://192.168.1.130:9090/api/v1/targets | python3 -c 'import json,sys

 `ipx` and `node` should be `up`. Every monitoring container should be running; after Docker
 restarts, one can be left `Exited (255)` though its policy is `unless-stopped` (Prometheus, on
 2026-10-12, when Docker lost its exit during an overload): `docker start` it and say so. blocky
 and nut on 192.168.2.21 are another machine, not ipx's; leave them. A container with no lines in
 an hour while it runs means Alloy is not shipping it; Alloy can take a few minutes to pick up a
 container after a deploy.
 ## Rules
 `docker logs` and `docker exec iPX ipx ...` are fine. On production's Postgres, `EXPLAIN (ANALYZE,
 BUFFERS)` of any query is allowed, read only, as CLAUDE.md's "Production's database" shows; any
 other query, ask the user first.

 The home page (`site/`, #216) is not on Tower. `sh site/build.sh` puts it in `site/dist` with the
 typeface, logo and icon from `web/`, and it goes to the Cloudflare Pages project `ipxreader` by
 direct upload, since there is no wrangler login here: hash each file as wrangler does (BLAKE3 of
 its base64 contents plus its extension, the first 32 hex digits, with the `blake3-wasm` package),
 ask the project for an upload token (`GET .../pages/projects/ipxreader/upload-token`), send the
 files to `/pages/assets/upload` with that token, then create a deployment
 (`POST .../pages/projects/ipxreader/deployments`) with the manifest of paths and hashes and
 `_headers`. Its screenshots (`site/shots`) come from a scratch iPX on public feeds, never
 production's, which would show whose subscriptions are whose.
 Testing sign-in from Tower itself proves nothing about the tunnel: Tower's own requests reach the
 published port as `192.168.1.130`, and Caddy rightly strips their `Cf-Access-*`. Send them from a
 container on another network, as cloudflared's are (#209).

 `crates/feed` is a library the two Rust services build in, not released (`0.0.0`); a change to it
 is a line in the changelog of each service it changes. The page shows ipx's version and its own in
 the logo's tooltip; the directory logs its own at start; each binary answers `--version`.
 Cutting a release of one: first read its `[Unreleased]` against its last release, not line by
 line, and rewrite it as what changed between the two. Lines go in as the work happens, so they
 record the way there: a feature added and then reworked in the same release is one line saying
 what it is now, under Added; something added and taken out again before the release, or a fix for
 a bug no release ever had, is not there at all; and "instead of" and "no longer" compare with the
 last release, not with last week. Issue numbers stay, all of them, on the line that survives. Then
 rename `[Unreleased]` to `## [X.Y.Z] - YYYY-MM-DD` and open a new empty `[Unreleased]` above it,
 set the service's version to `X.Y.Z` (dropping `-dev`), tag the commit with the service's tag, and
 update the compare links at the bottom of its changelog. Push the commit and the tag, build and
 deploy the service's image, then `sh scripts/release.sh ipx|directory|web` makes the Gitea
 release: that version's changelog section as its notes, and a tarball of what the image runs (the
 binary, or the page's files with the Caddyfile) attached, checked to be that version. Then, in the
 next commit, set its version
 to the next patch with `-dev` (after 0.9.0, `0.9.1-dev`), so a build between releases says so
 instead of claiming to be the last release. The release that follows can still be a minor or major
 one; `-dev` only says the work comes after `X.Y.Z`. A service never released is at `0.1.0-dev`,
 working towards its first release, `0.1.0`.
 **Traces first, logs second.** Anything that does work (a service, a handler, a job, a call to
 another service) gets spans, and passes `traceparent` on to whatever it calls, so one trace in
 Tempo follows a request or a job across ipx-web, ipx and the directory. A trace shows where the
 time went and what called what; a log line only that something happened. Log what a trace cannot
 carry: events worth counting on the dashboard, warnings and errors. A new service or route without
 traces is not finished.
 Deliberate simplifications get a `ponytail:` comment naming the ceiling and the upgrade path, e.g.
 `// ponytail: global connection mutex, move to a pool if feed count makes it contend`.

 # Changelog: ipx-directory
 The directory of public podcasts that ipx servers share (docs/directory.md). ipx's changelog is
 [crates/ipx/CHANGELOG.md](../ipx/CHANGELOG.md), the page's [web/CHANGELOG.md](../../web/CHANGELOG.md).
 Its version is in `crates/directory/Cargo.toml`, and a release is tagged `directory-vX.Y.Z`.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 ## [Unreleased]
 ## [1.2.0] - 2026-10-16
 ### Added
 - Answers and pages go out compressed, brotli, zstd or gzip as the caller takes them: the feed list ipx asks for was 603 KB of JSON. A snapshot may come gzipped, `/metrics` answers gzipped, and with `OTEL_EXPORTER_OTLP_COMPRESSION=gzip` traces go to the collector compressed (#253).
 - With `apple_country` set, Apple Podcasts' top charts for that country (the top 100 and the top 50 of each category) come into the directory every week, beside what servers share, without counting as subscribers; and a warning says when Apple's categories no longer match ipx's (#252).
 ### Changed
 - Each feed is checked every twelve hours instead of six (#243).
 - Feeds are fetched accepting brotli and zstd as well as gzip (#244).
 - On Postgres the server keeps all ten of its database connections open, so a request does not wait for a new one (#241).
 ## [1.1.1] - 2026-10-15
 ### Changed
 - The directory checks five feeds at a time, so a publisher that does not answer no longer holds up the rest of its round (#227).
 - A feed's server that takes 10 s to connect, or sends nothing for 15 s, is given up on (#230).
 ### Security
 - A failed feed check is logged without its address's query or password (#238).
 ## [1.1.0] - 2026-10-13
 ### Added
 - With `metrics_bind` set, the directory serves Prometheus metrics on a port of its own: memory, open files, and the feeds it has fetched and their bytes. A feed check's trace says how large the feed was (#224).
 ### Changed
 - The directory uses mimalloc instead of glibc's allocator, so it gives back memory it has freed instead of holding over a gigabyte while idle (#224).
 - The example in docs/directory.md has no healthcheck; `ipx-directory health` is still there to run by hand (#218).
 ### Security
 - A feed check's trace keeps the feed's address without its query or password (#225).
 ## [1.0.0] - 2026-10-12
 ### Added
 - Anyone can browse the directory in a web browser, read only: the most subscribed, categories, every feed A to Z, a search by name, and each feed's page with its latest items and its address to copy into any podcast app (#215).
 - `GET /v1/instances` lists the servers holding a snapshot, with their feeds and subscribers, for an admin token (#206).
 - `ipx-directory`, a directory of public podcasts that ipx servers share: each sends the public feeds its people subscribe to, and any server with a token browses them, each feed listed once it has been read. Tokens are in its config file, each read-only, read-write or admin, and revoked one at a time (#204, #205).
 - Traces: a span a request, joining the trace of the ipx server that called, and a trace a refresher round with a span a feed (#213).

 //! ipx's directory service (#204): a catalogue of public podcasts and blogs that ipx servers

 //! servers send which public feeds their people subscribe to, the directory fetches each
 //! feed's title, artwork, description and latest items on a slow schedule, and any server
 //! holding a token can browse it.
 //!
 //! The types here are the wire format, shared with ipx, which asks the directory on its

+# Changelog: ipx
-All notable changes to this project will be documented in this file.
+The daemon: the API, scans, downloads, DeadAir and the database. The page has its own changelog,
 [web/CHANGELOG.md](../../web/CHANGELOG.md), and the directory service its own,
 [crates/directory/CHANGELOG.md](../directory/CHANGELOG.md). Until 0.12.0 this was the changelog of
 all of ipx, the page included; they were split with the services (#207).
 Its version is in `crates/ipx/Cargo.toml`, and a release is tagged `vX.Y.Z`.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 ## [Unreleased]
 ## [1.3.0] - 2026-10-16
 ### Added
 - Signals: a feed of your own, picked out of the noise of everything you subscribe to, holding the items TypeSafe's Jev says are about the subject you give it: a name, words, and a sentence of your own if they are not enough, from the last 30 days and every new one, judged on your own TypeSafe key, each with an icon of its own if you like, which Jev can pick on the server's TypeSafe key (`POST /api/signals/icon`) (`/api/signals`, and `typesafe_key` on `/api/me`) (#254).
 - With `OTEL_EXPORTER_OTLP_COMPRESSION=gzip`, traces go to the collector compressed; `/metrics` answers gzipped, and a snapshot goes to the directory gzipped (#253).
 - A Directory request's trace shows the call to the directory whole, with the size of its answer, and the steps that match it against your subscriptions (#250).
 - The page's report of how long a list took to show after a click (`list_shown`, with the view and filter) is logged under that click's trace (#246).
 ### Changed
 - A feed that sends the same body again, as Patreon and Substack do whatever they are asked, is taken as unchanged instead of read again, and, without a schedule of its own, checked less often the longer it stays the same, up to every four hours, back on schedule when it changes (#242).
 - Feeds are fetched accepting brotli and zstd as well as gzip (#244).
 - On Postgres the daemon keeps all twenty of its database connections open, so a page load no longer waits for new ones, 80-330 ms each: the feed list and item lists took 0.3-1.6 s now and then, where their queries take 5-30 ms (#241).
 - Currently Listening and the Pinned filter answer in a few milliseconds: they read every item on the server, 1.3 s for Currently Listening (#249).
 ## [1.2.0] - 2026-10-15
 ### Added
 - `scan_done` on the event stream says which feed or folder the scan was limited to and whether someone asked for it (`only`, `forced`), so a page can tell the end of its own scan from a scheduled one's (#233).
 ### Changed
 - Check every feed looks up the site icons of feeds without artwork a few at a time, alongside the fetches, instead of one after another (#228).
 - A feed's server that sends nothing for 15 s is given up on, instead of holding a scan for the full 30 s; a feed that keeps sending still has 30 s (#230).
 - A scan's trace names the feed each fetch is for (#229).
 ### Security
 - A failure's words, and the addresses in an event, go to the log and to every open page without their query or password, where a private feed keeps its key: a failed fetch of a Patreon feed logged its `auth` key (#238).
 ## [1.1.0] - 2026-10-13
 ### Added
 - `/metrics` counts the feeds fetched and the bytes of their bodies (`ipx_feed_fetches_total`, `ipx_feed_bytes_total`), and a feed's trace says how large its body was (#224).
 ### Changed
 - ipx uses mimalloc instead of glibc's allocator, which gives freed memory back to the system: with glibc's, the memory a night of scans needed stayed held until a restart (#224).
 - `docker-compose.yml` has no healthchecks: Docker runs them with exec, which can fail on the host while ipx is well. The library's counts in `/metrics` are kept every 30 s by the daemon itself (#218).
 ### Security
 - Traces no longer keep a feed's or file's address with its query or password, where private feeds carry their credentials, such as Patreon's `auth` (#225).
 ## [1.0.0] - 2026-10-12
 ### Added
 - With a directory token that may administer it, ipx's admins remove a feed from the directory (blocking it) or check it now, list and unblock what is blocked, and list and drop the servers sharing (#206).
 - ipx passes its trace on when it calls the directory, so a Directory page is one trace from the browser to the directory (#213).
 ### Changed
 - The Directory comes from a directory service that iPX servers share, set up in Admin, Directory with its address and this server's token, instead of only this server's feeds. Sharing this server's public feeds with it is a setting, never a private one, and subscriber counts are every sharing server's. ipx sends the directory its feeds when they change, and every half hour (#205, #211).
 - A feed can be marked private, which keeps it out of the directory. A feed with a login, or whose address carries a key, is private already (#205).
 - ipx serves no page: the page is ipx-web's, which passes the API on to ipx, and ipx is built without node (#203).
 - `docker-compose.yml` is a sample to start from, ipx alone on SQLite with its folders beside the file, instead of a copy of the author's server (#208).
 - The source is a Cargo workspace: the daemon in `crates/ipx`, feed fetching and parsing in `crates/feed`. `cargo build --release` still makes `target/release/ipx` (#202).
 ## [0.12.0] - 2026-10-11
 ### Added
 - With `[web] metrics_bind` set, ipx serves Prometheus metrics on a port and thread of their own: the database pool, the worker's job and queue, jobs done and their time, scans, downloads and requests in progress, download speed, live-update listeners and missed updates, DeadAir's backlog, the artwork cache's fill, hit rate and evictions, memory, open files and the library's counts. (#194, #195, #198, #199).
 - The page reports its errors, the player's, how long play takes to start and how long it stalls to the server's log, and the requests one tap sets off share a trace, the playlist, audio and saved place of what it played included (#190, #192).
 - Saving an episode from a show with DeadAir on saves it without its dead air, at your breathing room (#186).
 - Choose the pause DeadAir leaves where it cuts a silence, from 0.2 to 0.5 seconds, for each show in its settings, as its breathing room, on a slider from brisk to relaxed. It is 0.3 seconds unless you change it, up from 0.2, which made speech sound rushed (#182, #183).
 ### Changed
 - DeadAir no longer makes a shortened copy of each episode. It plays the original with its long silences left out, ready a few seconds after the download, with no gap where a silence was cut and no extra disk space; the copies already made are removed (#179, #181, #196).
 - DeadAir is in the same box as a show's download settings, below them, and stays there when automatic downloads are off (#185).
 - The container is built on Debian 13 (trixie) instead of 12, so DeadAir uses ffmpeg 7.1 instead of 5.1 (#177).
 - On Postgres, ipx keeps up to 20 connections to the database instead of 10, for the bursts of a page load asking for many covers at once (#200).
 - Traces of the disk sweep, episode lists and DeadAir's work on each file show each step, and the sweep's trace says what it removed (#187).
 ### Fixed
 - All Subscriptions, and every item list, comes up faster, most of all the first time after a quiet spell: it took half a second to two (#188).
 - Checking for new episodes no longer waits up to 12 seconds each time on a clear-out of dead feeds from the Directory, which now runs once a day (#193).
 - A page left open no longer misses updates after a check for new episodes: the note that each feed not due was skipped, one per feed, filled the queue they share (#197).
 ### Security
 - Cloudflare no longer keeps a copy of the audio you play, which it served to anyone it let in without checking they subscribe (#189).
 ## [0.11.0] - 2026-10-09
 ### Added
 - DeadAir: turn it on for a show in its settings, or with the button beside the speed while it plays, and its episodes play with long silences shortened, so podcasts finish sooner without sounding sped up. Your place carries over when you turn it on or off, each episode says how much shorter it is ("Cutting dead air…" until it is done), and Settings shows the time it has saved you. It is off for every show until you turn it on (#171, #172, #173, #174, #176).
 ### Fixed
 - A downloaded file's play, save, share and delete buttons stay on one row in the Files pane, instead of delete wrapping underneath (#175).
 - Cover art up to 20 MB is shown, instead of nothing for anything over 5 MB, as for five of the Glass Cannon Network's feeds.
 - Seeking in an episode while many people listen answers in about 10 ms instead of 40, and files stream about four times as fast: each connection now sends what is ready without waiting for the browser to acknowledge the last part.
 - Artwork that could not be fetched is not fetched again for an hour, instead of on every page load, and the server's log says which image it was and why.
 ## [0.10.3] - 2026-10-09
 ### Changed
 - Swiping past the last item shows the theme's accent colour, without the words "No more items".
 - An empty list and the reader with nothing picked say nothing, instead of "Nothing here yet — try Scan now." and "Pick an item to read it."; a search that finds nothing still says so.
 - In Settings, the API tokens sit in a box of their own.
 - A feed's settings are redesigned: downloading on its own is a switch with what depends on it beneath, how many is Default, Newest or All shown on a strip of the show's own episodes, words to pick or hide are chips, the feed's address is at the top with a copy button, and Save is always in reach. Its folder and Directory category are no longer in it.
 - The feed list's traces show each of its database queries, so it can be told where its time goes.
 - Saving a feed's settings asks the database for your subscription once, not twice.
 - `ipx add` and Add feed in the page add a feed the same way, through one piece of code.
 - A pinned item or feed's pin button is filled with the theme's accent, in the reader, on the feed's page and in the toolbar, so pinned no longer looks like not pinned.
 - A feed's page in the Directory says how many people here subscribe only when someone does, without "Nobody here subscribes yet".
 ### Fixed
 - The unread counts catch up when you come back to the page: an item read on another device, or while the phone app was in the background, no longer stays counted as unread until a reload.
 - A feed set to download 0 of its newest items downloads all of them, the whole back catalogue, as the server's 0 does; it downloaded nothing.
 - The feed list loads faster: it counts the items and files of your own feeds, not of every feed on the server, and asks for a group's title once, not once for every feed in it.
 - Downloading or deleting a file the server no longer has answers "not found" instead of a server error.
 - A feed's page in the Directory, and subscribing from it, no longer wait while the whole Directory is put together to check that the one feed is in it.
 - An episode that came as a torrent of several files plays its largest file, and can be deleted, by hand or to free space, instead of staying on disk for good.
 - Removing an account takes the feeds only that person read off the server, as unsubscribing does, instead of leaving them downloading every new episode for no one.
 - Freeing disk space counts only the people who subscribe to a feed: an episode is no longer taken as heard by everyone because someone who has since unsubscribed heard it, and their pins no longer keep files for good.
 - An episode whose file turns out to be a torrent shows as downloaded once it is, instead of being fetched again on every check of its feed, and no longer holds up the checking of other feeds while it downloads and seeds.
 - Downloading the latest 65 to 100 items of a feed queues them at once, instead of hanging until most had downloaded and holding up adding feeds and Refresh meanwhile.
 - Changes to the feed list made at the same moment, such as two people adding feeds, or a feed added while the server settings change, no longer undo one another.
 - A download that stops partway is given up after two minutes without data, instead of holding up every scan and download until a restart.
 - On a phone, the closed feed list no longer shades the left edge of the page with its shadow.
 - On an iPhone, the top bar's colour runs all the way up behind the status bar and the Dynamic Island, with no band of another colour above it. In Glass the bar is solid on a phone, in the colour its glass showed.
 - A feed's buttons stay on one row on a narrow phone, and the reader's buttons stay together instead of breaking across lines under a long feed name.
 - A moment's DNS failure no longer marks a feed as failing for a day or calls it gone: iPX tries it again in ten minutes. One failed lookup one morning left 205 podcasts unread, uncategorised and labelled gone until the next day. A name that does not resolve is said to be maybe gone, and only once it has been failing a day, on its Directory page as on its own.

 - Adding an address checks it first: a feed is added, a web page adds the feed it links, and anything else is refused with the reason, instead of being added and failing on every check.
 - A feed that was failing when its last subscriber left is forgotten, rather than kept with its error for good. One that worked, or has files on disk, is kept as before.
 - A feed that keeps failing is checked less and less often, waiting as long as it has been failing, up to once a day; it goes back to its schedule as soon as it works. Refreshing it still checks it at once.
 - A scan's trace shows the time a feed spends on its artwork and in the database after the fetch.

 //! DeadAir (issue #171): podcasts play with their long silences shortened, so they finish

 //! Nothing is copied (#181). DeadAir finds a file's silences once, in the background, and keeps a
 //! `Plan` for each pause length a person can choose (#182): the frames kept, as byte ranges of
 //! the original. The player gets an HLS playlist of those ranges (`playlist`), which Safari plays
 //! itself and other browsers through hls.js, with no gap at the cuts. Seeking past each silence
 //! instead left about 1.3 s of nothing at every one (#178); a copy made with ffmpeg cost as much
 //! disk again as the original and could only have one pause length.
 //!
 //! Positions stay in the original's time. What a plan leaves out is stored as `Cut`s of the
 //! original's time, and the server converts both ways (`to_copy`, `to_original`): the iOS and
 //! Android apps save positions themselves, from their own player, so converting in the page
 //! would miss them.

 # How it works
-One binary, `ipx`. `ipx daemon` runs three things in one process: a scheduler, a Unix-socket
+Three services, each a container of its own with its own version and changelog (#207):
-control server, and the web UI. Everything else is a CLI that either does the work itself or hands
+
-it to a running daemon.
+| Service | What it is | Source | Image |
 |---|---|---|---|
 | ipx-web | Caddy: serves the page, a static site built from `web/`, and passes `/api` and `/media` to ipx on the same address. It asks ipx before it serves the app or the admin page (`/api/page-check`) | `web/`, `web/Caddyfile` | `Dockerfile.web` |
 | ipx | The daemon and CLI, one binary. `ipx daemon` runs a scheduler, a Unix-socket control server and the HTTP API in one process; everything else is a CLI that either does the work itself or hands it to a running daemon | `crates/ipx` | `Dockerfile` |
 | ipx-directory | The directory of public podcasts that ipx servers share. ipx asks it on its people's behalf; the page never talks to it ([directory.md](directory.md)) | `crates/directory` | `Dockerfile.directory` |
 The Rust source is a Cargo workspace (#202); `crates/feed` (`ipx-feed`) fetches and parses feeds
 for both Rust services. Versions: ipx's in `crates/ipx/Cargo.toml`, the directory's in
 `crates/directory/Cargo.toml`, the page's in `package.json`; CLAUDE.md has the release steps.
 ## Traces and logs
 A request is one trace (#213). The page starts one for each tap and sends `traceparent` with its
 requests (#190); Caddy's span continues it and passes it on to ipx; ipx's request span, its steps
 and its calls to the directory follow, and the directory's request span joins it. Scans,
 downloads, DeadAir's work, shares with the directory and the directory's refresher rounds are
 traces of their own. All three log one JSON object a line, for Loki; ipx's lines carry their trace
 id, and Caddy's request lines theirs. ipx also serves Prometheus metrics (`[web] metrics_bind`,
 #194). The exporter and the `traceparent` handling both Rust services use are in
 `crates/directory/src/otel.rs`.

 A Signal (#254, [signals.md](signals.md)) is a feed someone makes from their own subscriptions. `signals::run`, a task of its
 own beside DeadAir's, woken by a scan with something new or a Signal made or changed, asks Jev
 about each item of the last 30 days that has no verdict yet for one of its owner's Signals: one
 call an item, a noul question a Signal, on the owner's `users.typesafe_key`. Every answer is kept,
 fitting or not, so nothing is asked twice; new keywords drop the Signal's verdicts. A Signal's
 items are `entries_where` with an `EXISTS` on its hits, so read state is the item's own.
 Read state is `entry_state` alone. `entries` had `read`, `flagged` and `position` columns from
 before accounts; two bugs came from queries still reading them, and they were dropped in 0.5.

 # The directory
 `ipx-directory` is a catalogue of public podcasts and blogs that ipx servers share (#204). An ipx
 server sends it the public feeds its people subscribe to, and how many of them do. The directory
 fetches each feed's title, artwork, category, description and latest twenty items every twelve hours,
 and any server holding a token can browse it. It never downloads a file, and it never stores
 one's address: every ipx server still fetches its own feeds.
 This server's is at `https://directory.ipxreader.app` (until 2026-10-12 `ipx-dir.sdf1.net`, #214), the `ipx-directory` service of the Arcane project
 `ipx`, with its database `ipx_directory` on the `databases` project's Postgres.
 ## In ipx
 An admin sets it up in **Admin, Directory**: the directory's address, the token its operator gave
 this server, and whether to share. ipx asks the directory on its people's behalf, so the page never
 talks to it and never sees the token or a feed's address. With no directory set up, the Directory
 says so and feeds are added by their address.
 ipx keeps the address and token with its other server settings, in its database (`settings`,
 `directory_url` and `directory_token`), not in config.toml. The token is written, never shown
 again: the tab says it is set and offers to clear it. To replace one, make a new token on the
 directory, paste it over the old, then delete the old token's entry from the directory's config.
 With sharing on, ipx sends its snapshot when what it would send has changed (checked after every
 scan, and whenever the catalogue or these settings change), and every half hour regardless (#211): each feed checked at least once, with how many people here subscribe,
 and the category an admin gave a feed that names none. It never sends an OPML or a Patreon creator
 itself (their feeds go instead), or a private feed. A feed's settings have a **Private** switch for
 a paid feed iPX does not recognise by its address; anyone subscribed may turn it on, and only an
 admin off.
 When this server's token is `rwa`, its admins administer the directory from iPX (#206). A feed's
 page in the Directory has **Check now** and **Remove from the directory**, which blocks it so no
 server's snapshot brings it back. Admin, Directory lists the **Servers** sharing, by token name,
 with how many feeds and subscribers each gave, and **Blocked**, by title, with Unblock. Dropping a
 server's snapshot takes its feeds and counts out until it next shares; to keep a server out,
 revoke its token. An admin's own subscriptions open as their feeds, not as Directory pages, so
 removing one of those is done by marking it private, or from another admin's account.
 ## In a web browser
 Anyone may browse it at its address, no token and no sign-in (#215): the most subscribed, the
 categories, every feed A to Z, a search by name, and a page for each feed with its description,
 its latest items and its address, with a Copy button, to subscribe to in any podcast app or feed
 reader. The pages only read: nothing in them changes the directory. They are rendered by the
 directory itself from what the API serves, with the publisher's HTML shown as text, an item's link
 only when it is http(s), and a Content-Security-Policy that allows the site's own script and
 stylesheet and the covers, which load from their publishers. `/v1` is the API and still needs a
 token for everything.
 ## Tokens
 Everything but `/healthz` needs a token, sent as `Authorization: Bearer <token>`. Each one has a
 name and one of three levels of access:
 | | browse | send snapshots | remove, block, refresh feeds; drop a server's snapshot |
 |---|---|---|---|
 | `ro` | yes | | |
 | `rw` | yes | yes | |
 | `rwa` | yes | yes | yes |
 Tokens are in the config file and nowhere else, and no level of access can make or revoke one
 over the API. To make one:
 ```sh
 docker exec ipx-directory ipx-directory token new <name> --access ro|rw|rwa
 ```
 It prints the token, to give to whoever it is for, and the lines to add to the config file. The file
 holds the token's SHA-256, never the token. The directory reads the file again within a minute of
 a change, so adding a token and revoking one (deleting its entry) need no restart. A revoked token
 also takes the counts its server sent. A file that does not load (a misspelled `access`, two tokens
 with one name) leaves the tokens as they were, and the log says why.
 ## The config file
 `/config/directory.toml` in the container (`DIRECTORY_CONFIG`, or `--config`), on Tower
 `/mnt/fast/appdata/ipx-directory/directory.toml`:
 ```toml
 bind = "0.0.0.0:8100"
 # Prometheus metrics, on a port of their own and not the one the tunnel publishes. Empty, or
 # left out, serves none.
 metrics_bind = "0.0.0.0:9188"
 # Apple Podcasts' top charts for this country, weekly (see below). Empty, or left out: none.
 apple_country = "ca"
 # The environment variable holding the database URL: postgres://... or sqlite://...
 database_url_env = "DIRECTORY_DATABASE_URL"
 [[tokens]]
 name = "tower"
 access = "rwa"
 token_sha256 = "…"
 ```
 `DIRECTORY_LOG_FORMAT=json` logs one JSON object a line, for Loki, as ipx's `IPX_LOG_FORMAT` does.
 Each request is a line with its `method`, `path`, `status`, `duration_ms` and the `token`'s name.
 With `OTEL_EXPORTER_OTLP_ENDPOINT` set (`http://host:4318`, OTLP over HTTP), it sends traces: a
 span a request, a child of the caller's when the request carries a `traceparent`, as ipx's do, and
 a trace a refresher round with a span a feed (#213). `OTEL_RESOURCE_ATTRIBUTES` tags them, as
 production does with `deployment.environment.name=production`. Its version is in
 `crates/directory/Cargo.toml`, logged at start and answered by `ipx-directory --version`; its
 changelog is `crates/directory/CHANGELOG.md`.
 ## Apple Podcasts
 With `apple_country` set, the directory takes Apple Podcasts' top charts for that country once a
 week (#252): the top 100 overall and the top 50 of each of Apple's categories, about a thousand
 shows. Apple's lookup API gives each one's RSS address, and they go in as a snapshot of their own,
 `apple-podcasts`, with no subscribers: fetched, sorted into categories and listed like any other
 feed, while the most subscribed stay what the servers sharing here subscribe to. A show Apple drops
 from its charts leaves the directory at the next sync, unless a server shares it. An admin can drop
 the snapshot as any server's (`DELETE /v1/instances/apple-podcasts`); the next sync brings it back.
 No token may be named `apple-podcasts`.
 The same sync compares Apple's list of categories with the one ipx keeps (`CATEGORIES` in
 `crates/feed`) and logs a warning naming what differs, for whoever checks the log to update it.
 It runs at start when the last sync is a week old, and a failed one tries again an hour later. Each
 sync is a trace (`apple_sync`, a span for each of Apple's answers), and a line `Apple Podcasts
 synced` says how many shows came and went in.
 ## Running one
 ```yaml
 services:
  ipx-directory:
    image: ipx-directory          # docker build -f Dockerfile.directory -t ipx-directory .
    restart: unless-stopped
    environment:
      DIRECTORY_DATABASE_URL: "postgres://ipx_directory:password@db-host:5432/ipx_directory"
    ports:
      - "8100:8100"
    volumes:
      - ./directory:/config:ro    # directory.toml
 ```
 ## What it will not hold
 A private feed is never meant to reach it. ipx leaves out a feed marked private, one with a
 username or password, and one whose address `ipx_feed::url_looks_private` catches: a paid-feed
 host, or a key in the query. The directory checks every address it is sent with the same function
 and refuses what it catches, so one server's miss does not publish someone's paid feed to every
 other. What both miss, an `rwa` token can remove: `DELETE /v1/feeds/{id}` removes the feed and
 blocks it, so no snapshot brings it back.
 ## API
 | Route | Access | |
 |---|---|---|
 | `GET /healthz` | none | `ok` when it can read its database |
 | `GET /v1/me` | ro | the token's `name` and `access` |
 | `GET /v1/feeds` | ro | every feed A to Z: `id`, `url`, `title`, `image`, `category`, `subcategory`, `podcast`, `subscribers` |
 | `GET /v1/popular?limit=10` | ro | the most subscribed, at most 100 |
 | `GET /v1/feeds/{id}` | ro | one feed, with `description`, `failing` (why its last check failed, in words) and its latest twenty `items` (`guid`, `title`, `link`, `published`, `duration`, `description`), never their files |
 | `POST /v1/snapshot` | rw | `[{"url", "subscribers"}]`, at most 20,000: replaces everything this token sent before; answers what it `accepted` and how many it refused as private, blocked or invalid |
 | `DELETE /v1/feeds/{id}` | rwa | remove and block |
 | `GET /v1/blocked`, `DELETE /v1/blocked/{id}` | rwa | what is blocked; unblock |
 | `GET /v1/instances` | rwa | each token holding a snapshot: its `name`, `feeds` and `subscribers` |
 | `DELETE /v1/instances/{name}` | rwa | drop one token's snapshot, its counts with it |
 | `POST /v1/feeds/{id}/refresh` | rwa | fetch the feed now, answering with its page |
 A feed's `id` is the first 64 bits of the SHA-256 of its address, normalised (scheme and host in
 lower case, no default port or fragment), so every server arrives at the same id. `subscribers`
 is the sum over every token's latest snapshot. A feed is listed once the directory has read it as
 a feed, so an OPML or an address that never worked is not, and goes when no snapshot has it any more. Descriptions
 are the feed's own HTML, unsanitized: whoever shows them sanitizes them, as ipx does.

 # Signals
 A Signal is a feed someone makes from their own subscriptions (#254). They give it a name, the
 words to listen for (`formula 1`, `f1`) and, when those are not enough, a sentence saying what they
 mean (#259). TypeSafe's Jev reads each item of the feeds they subscribe to and picks out the ones
 about that subject: the name, the words and the sentence together, not any one word. Those items show in the Signal as well as in their
 own feed. The rest stays noise, where it was.
 Each person brings their own TypeSafe key, entered in Settings. Nothing is judged for someone
 without one. Jev is asked once for each item, on that person's key, with one question for each of
 their Signals that has not heard about the item yet.
 ## What someone sees
 - **The sidebar.** A Signals folder comes first in the feed list, under All Subscriptions (#255,
  #256). It is closed or open as an OPML's folder is, remembered in each browser. Its row is like
  any folder's (#265); New signal is the + on the folder's page. Inside the folder are the
  person's Signals, each with its items and unread counted under its name.
 - **An icon of its own** (#261), chosen in the Signal's dialog from all of Font Awesome Free 7.3.1,
  the set the page's own icons come from: 2,883 icons, solid, regular and brands, searched by name
  and Font Awesome's search terms ("ai" finds the robot). Without one, a Signal shows its initials.
  **Auto** asks Jev to choose (#263), and a Signal made without an icon gets Jev's pick by
  itself, a moment after it is made. Every Signal's tile is in the accent tint the folder has.
 - **Each Signal's row** says "12 items · 3 unread", as a feed's row counts its own.
 - **The folder's page** lists the Signals, as an OPML's page lists its feeds, with the + for a new one.
 - **A Signal's page** is an ordinary item list: All, Unread, Downloaded and Pinned, search and sort.
  Its header says what it listens for (the sentence, or the words), and that nothing is picked
  out without a key. Edit changes the name, the words or the sentence; Delete removes the Signal
  and leaves the items in their feeds.
 - **Read state is the item's.** Reading an item in a Signal reads it in its feed, and the other way
  round. The counts follow without a reload (#258).
 - **Settings, TypeSafe key.** A password field. A key saves on leaving the field, and the bin
  forgets it. The key is never sent back to the page, which only learns whether one is set.

 ```
 The judge is a task of its own beside DeadAir's (`crates/ipx/src/signals.rs`), not a job on the
 scan worker, so a slow TypeSafe never holds up a scan.
 ### Which items are asked about
 `Db::unjudged` finds, newest first, up to 50 items that are:
 - in a feed the Signal's owner subscribes to,
 - published (or, with no date, first seen) in the last 30 days (`SIGNAL_DAYS`),
 - not hidden from them by their block lists,
 - not yet in `signal_verdicts` for that Signal,
 - for someone with a key that TypeSafe has not refused since the daemon started.
 So a new Signal looks back a month, and after that sees each new item. A show subscribed to today
 has its back catalogue skipped, apart from its last month.
 Rows for one item and one person are grouped, so an item is one call whatever the number of
 Signals. A full batch means there may be more, and the next pass starts at once. Otherwise the
 judge sleeps until woken or for 5 minutes.
 ### Every answer is kept
 `signal_verdicts` records each answer, fitting or not. An item with no row has not been asked yet;
 an item with a row is never asked again. So the cost is one call per item per person, once.
 Changing a Signal's name, words or sentence deletes its verdicts, and everything in the window is
 asked again. The first start with sentences (#259) deleted every verdict, since they answered the
 old question.
 ## TypeSafe
 Jev is TypeSafe's System One model, already used to pick a feed's Directory category
 (`feed::classify`). The address is `feed::JEV_URL`, `https://api.typesafe.ai/v1/systemone`.
 Signals use the **noul** question type, which answers how likely a statement is true, from 0 to 1.
 Questions in one call are judged independently and in parallel.
 ### A request
 Sent with `Authorization: Bearer <the person's key>`, for an item and two of their Signals:
 ```json
 {
  "model": "jev-latest",
  "state": "Feed: Pit Lane\nTitle: Monaco qualifying\n\nQualifying report from the Monaco Grand Prix.",
  "questions": {
    "signal_3": {
      "type": "noul",
      "instructions": "The reader follows a subject they call \"F1\", described by these words: formula 1, f1. Is this item about that subject?",
      "criteria": {
        "true": "The item's main subject is that subject, as the name, the words and the reader's description together describe it.",
        "false": "It is about something else, or touches the subject only in passing."
      }
    },
    "signal_4": {
      "type": "noul",
      "instructions": "The reader follows a subject they call \"Food\", described by these words: baking. In their own words: Bread and cakes, not restaurants. Is this item about that subject?",
      "criteria": {
        "true": "The item's main subject is that subject, as the name, the words and the reader's description together describe it.",
        "false": "It is about something else, or touches the subject only in passing."
      }
    }
  }
 }
 ```
 - `state` is text: the feed's title, the item's title, and its show notes with the HTML taken out,
  cut to 2,000 characters (`TEXT_CHARS`).
 - Each question is keyed `signal_<id>`, and its answer comes back under the same key.
 - `criteria` is an object saying what true and false mean. A sentence there is refused with a 422
  (#257).
 - **One subject, not any word.** The first question was "Is this item about any of these: ai,
  development, programming?", so one broad word was enough: AI Development took Sega pulling a game
  remaster (0.90), a Surface Laptop review (0.95) and a C++ tutorial (0.99), 54 items in all. Asked
  about the subject, with the sentence "AI tools for writing software: coding agents, AI dev tools,
  vibe coding, AI in code review.", those scored 0.06, 0.16 and 0.02, and 5 of the 54 stayed in,
  AI code review in the Linux kernel highest at 0.94 (#259).
 ### Its answer
 What TypeSafe answered to a request of this shape, on 2026-10-16:
 ```json
 {
  "model": "jev-1.13.0",
  "answers": {
    "signal_3": { "type": "noul", "noul": 0.96 },
    "signal_4": { "type": "noul", "noul": 0.02 }
  },
  "usage": { "input_tokens": 389, "output_tokens": 40 }
 }
 ```
 0.5 or more is a fit (`THRESHOLD`): the item goes into Signal 3 and not Signal 4. A question
 missing from the answer is left unjudged and asked again next pass.
 ### When TypeSafe says no
 | TypeSafe answers | What the judge does |
 |---|---|
 | 401, 402, 403 | The key is refused. That person is passed over until they save a key or the daemon restarts, so a bad key is not sent the whole queue. Logged once: "TypeSafe refused a Signal key". |
 | 400, 422 | The request itself is wrong, so every item's would be. The pass ends; the items wait for the next one. Logged: "TypeSafe refused a Signals request as malformed", with TypeSafe's reason. |
 | anything else, or no answer | That item is left unjudged and asked again next pass. Logged: "Jev could not judge an item". |
 The error keeps TypeSafe's reply, cut to 500 characters, for example:
 ```
 TypeSafe answered 422: {"detail":[{"type":"model_attributes_type","loc":["body","questions","3","noul","criteria"],"msg":"Input should be a valid dictionary or object to extract fields from","input":"Yes if the subject is one of them."}]}
 ```
 ## The API
 Every route is the signed-in person's own. A Signal of someone else's is not found, as one that
 does not exist.
 ### `GET /api/signals`
 ```json
 [
  { "id": 1, "name": "AI Development", "keywords": ["ai", "development", "programming"],
    "description": "AI tools for writing software: coding agents, AI dev tools, vibe coding, AI in code review.",
    "icon": "solid/laptop-code", "items": 48, "unread": 5 },
  { "id": 2, "name": "Apple", "keywords": ["apple", "mac", "iphone"], "description": null, "icon": null, "items": 272, "unread": 0 }
 ]
 ```
 `items` counts the items Jev picked out that are still in a subscribed feed and not hidden, what
 its list shows; `unread` those of them not read.
 ### `POST /api/signals`
 ```json
 { "name": "Formula 1", "keywords": ["formula 1", "f1"], "description": "Grand prix racing, not road cars." }
 ```
 Answers `{ "id": 3 }` and wakes the judge. A name is 1 to 100 characters. Between 1 and 50 words
 are allowed, each up to 200 characters, kept once whatever their case. `description` is optional,
 up to 500 characters. Anything else is a `400` saying so.
 ### `PATCH /api/signals/{id}`
 Any of the three: `{ "name": "F1" }`, `{ "keywords": ["f1", "grand prix"] }`,
 `{ "description": null }` (null or empty clears it), `{ "icon": "solid/robot" }`. A change to the
 name, words or sentence drops the Signal's verdicts and wakes the judge, since each is part of the
 question; a new icon does not. The page sends only what changed. An icon is `solid/`, `regular/` or
 `brands/` and a plain name, since the page puts it into an address: anything else is a `400`. Answers `204`, or `404` for a Signal that is not yours.
 ### `DELETE /api/signals/{id}`
 Answers `204`. The Signal and its verdicts go; the items stay in their feeds.
 ### `GET /api/signals/{id}/entries`
 The same query as a feed's list, `offset`, `limit`, `filter`, `q`, `sort`, `dir`:
 ```
 GET /api/signals/3/entries?filter=unread&sort=published&dir=desc&limit=50
 ```
 ```json
 {
  "total": 1,
  "entries": [
    {
      "guid": "sig-1", "feed_id": "pit-lane", "title": "Monaco qualifying",
      "link": "https://pitlane.example/monaco", "published": 1792170000,
      "description": "<p>Qualifying report…</p>", "read": false, "flagged": false,
      "image": null, "duration": null, "episode": null, "season": null, "position": 0,
      "enclosures": []
    }
  ]
 }
 ```
 Reading or pinning one is the item's own route, `POST /api/entries/{feed_id}/{guid}/flags`, as
 anywhere else.
 ### `PATCH /api/me`, the key
 ```json
 { "typesafe_key": "ts_…" }
 ```
 A string saves the key and lets the judge try it again. `null` or an empty string forgets it. A
 key is up to 500 printable characters. `GET /api/me` says `"typesafe_key_set": true` and nothing
 more.
 ### `POST /api/signals/icon`
 Jev's pick of an icon, on the **server's** `TYPESAFE_KEY`, not the person's: it is the page's own
 doing, once a Signal. Jev chooses among options and cannot name one, so the page searches Font
 Awesome's index for each word of the name, words and sentence, the best six each, and sends up to 40:
 ```json

 ipx asks a **choice** question, each candidate a choice and its label and terms what it means:
 ```json
 {
  "model": "jev-latest",
  "state": "Signal: AI Development\nListens for: ai, development, programming\nIn their words: AI tools for writing software: coding agents, AI dev tools, vibe coding, AI in code review.",
  "questions": { "icon": {
    "type": "choice",
    "instructions": "Which icon best stands for this subject in a list of the reader's topics?",
    "criteria": { "solid/robot": "Robot: ai, android, bot, machine", "solid/laptop-code": "Laptop Code: computer, cpu, dell, demo" }
  } }
 }
 ```
 TypeSafe answered, on 2026-10-16, for six candidates:
 ```json
 { "model": "jev-1.13.0", "answers": { "icon": { "type": "choice", "choice": "solid/laptop-code", "confidence": 0.34,
  "probabilities": { "solid/robot": 0.4, "solid/code": 0.14, "solid/laptop-code": 0.45, "solid/brain": 0.01, "solid/microchip": 0.0, "solid/terminal": 0.0 } } } }
 ```
 The answer is `{ "icon": "solid/laptop-code" }`, only ever one it was offered. Each candidate has to
 be an icon name the API takes, 1 to 60 of them. `404` when the server has no key, `502` when Jev
 fails (logged: "Jev could not pick an icon"). The call has a `jev_icon` span.
 ### The event
 Once a pass, for each person it found items for, the judge sends this on the event stream
 (`/api/events`):
 ```json
 { "ev": "signal_hits", "user": 2, "hits": 3 }
 ```
 A page with Signals fetches `/api/signals` again, and the open Signal's list.
 ## Data
 ```mermaid
 erDiagram
    users ||--o{ signals : owns
    signals ||--o{ signal_verdicts : "has heard of"
    entries ||--o{ signal_verdicts : "judged in"
    users {
        bigint id
        text typesafe_key "NULL: no key"
    }
    signals {
        bigint id
        bigint user_id
        text name
        text keywords "JSON array"
        text description "NULL: none"
        text icon "solid/robot, NULL: initials"
        bigint created
    }
    signal_verdicts {
        bigint signal_id "PK"
        text feed_id "PK"
        text guid "PK"
        bool hit
    }
 ```
 - `signals` and `signal_verdicts` are created from their entities like every table
  (`crates/ipx/src/entity.rs`). `users.typesafe_key`, `signals.description` and `signals.icon`
  were added to existing tables, so `create_missing` adds each column when it is missing.
 - The icons are files of ipx-web's, not the database's: `web/build.mjs` copies Font Awesome Free's
  SVGs to `/icons/<style>/<name>.svg`, kept a day, and writes `/icons/index.json`, names, labels
  and search terms, about 90 KB compressed, named by its hash and fetched when the picker first
  opens. A Signal's tile draws its one file as a CSS mask, so it takes the theme's colour.
 - A Signal's list is `entries_where` with
  `EXISTS (SELECT 1 FROM signal_verdicts v WHERE v.signal_id = $n AND v.feed_id = e.feed_id AND v.guid = e.guid AND v.hit)`
  on top of the subscribed-feeds scope. So filters, search, sort, block lists and read state all
  work as for All Subscriptions.
 - A verdict for a Signal deleted while Jev was being asked is not stored. Postgres's foreign key
  would refuse it, and SQLite would keep it for nothing.
 ## Watching it
 | | |
 |---|---|
 | Traces | A `signals` span for each pass (`entries`), and a `jev` span for each call (`user`, `signal_count`, `http.response.status_code`, and TypeSafe's reply as `error` when it refuses). |
 | Log, counted | `ev="signal"`, "an item fits a Signal", for each item with a fit: `user`, `feed`, `new` (how many of their Signals it fits). |
 | Log, warnings | The three in the table above. |
 | Events | `signal_hits` on the socket and `/api/events`. |
 ## Limits
 - **The key is kept in plain text** in `users.typesafe_key`, because every call needs it whole. It
  should be encrypted with a server key if the database is ever shared with anything else.
 - **Refused keys are remembered in memory**, so a restart tries each once again.
 - **Keywords changed while an item is being judged** can leave that one item's verdict from the old
  words.
 - **There is no meter** of how many calls a key has made. It is one call per item in the person's
  feeds in the window: a person with 1,500 feeds busy enough to publish 3,000 items a month spends
  about 3,000 calls the first month and then as many as come in.
 - **Only the last 30 days** are ever judged, by publish date.
 ## Testing
 - `cargo test -p ipx`: the request's shape and the threshold (`signals::tests`), and the queue,
  verdicts, ownership, unread counts and new keywords (`db::tests::a_signal_shows_what_jev_said_fits_and_only_to_its_owner`),
  on SQLite and Postgres both.
 - `node --test tests/page-unit.js`: a Signal's place id and its list's address.
 - `npx playwright test -g Signal`: makes a Signal from the folder's +, and checks that the matching
  item shows and that reading it reads it in its feed and clears the badge. TypeSafe is stood in for
  by the fixture server's `/jev` (`IPX_TYPESAFE_URL`), which refuses the shape TypeSafe refuses, and
  `/signal.xml` is dated today, since only the last 30 days are judged.

 ### Behind ipx-web (#203)
 With the page served by `ipx-web` (Caddy), cloudflared reaches Caddy instead, still through the
 host's port 8099, so its requests still arrive from `192.168.64.1`, at Caddy now. Caddy passes the
 `Cf-Access-*` headers on only from that address (`TUNNEL_PEER`) and strips them from everyone else,
 the boundary `trusted_proxies` drew before. ipx then sees every request come from Caddy, so
 `trusted_proxies` names Caddy's address on `ipx_default`, pinned in the compose file
 (`192.168.64.10`), instead of the gateway. The token check is unchanged: a header Caddy passes on
 still needs a valid `Cf-Access-Jwt-Assertion`.

  intro: `<p>The HTTP API of an iPX server: everything the page does, a script can do. Every request
    and answer is JSON unless an item says otherwise. The page is served by ipx-web, which passes
    <code>/api</code> and <code>/media</code> on to ipx at the same address, so a script talks to
    the address people open in a browser.</p>
    <h2 id="auth">Signing in</h2>
    <p>Send an API token, made in Settings under API tokens or with <a href="${'/docs/api/ipx/auth/post-tokens'}"><code>POST /api/tokens</code></a>:</p>
    <pre><code>Authorization: Bearer ipx_…</code></pre>
    <p>A token acts as the person who made it, and is an admin only if they are. A browser signs in
    with <a href="/docs/api/ipx/auth/post-login"><code>POST /api/login</code></a> instead and is
    given a cookie. Behind Cloudflare Access, Access stops a request with no Access sign-in before
    iPX sees it: send an Access service token's <code>CF-Access-Client-Id</code> and
    <code>CF-Access-Client-Secret</code> beside the API token.</p>
    <h2 id="errors">Errors</h2>
    <p>A request that fails answers with its status and a sentence saying why, as plain text:
    <code>401</code> not signed in, <code>403</code> an admin's to do, <code>404</code> not there or
    not yours, <code>400</code> a request that cannot be done as asked, <code>409</code> a conflict
    the answer explains.</p>
    <h2 id="ids">Ids</h2>
    <p>A feed's id is a short name made from its title, such as <code>99-invisible</code>, and
    appears in the page's address when the feed is open. An episode is its feed's id and its
    <code>guid</code>, the guid URL-encoded in a path. A file (an enclosure) has a number. Times are
    Unix seconds.</p>`,

  intro: `<p>The HTTP API of the directory of public podcasts that iPX servers share, at
    <code>${D}/v1</code>. Its pages at <a href="${D}">${D.replace('https://', '')}</a> are anyone’s
    to browse; the API needs a token for everything.</p>
    <h2 id="auth">Tokens</h2>
    <pre><code>Authorization: Bearer &lt;token&gt;</code></pre>
    <p>A token has a name and one of three levels of access: <code>ro</code> reads,
    <code>rw</code> also shares, and <code>rwa</code> also removes and blocks feeds and drops a
    server’s share. Tokens are given out by whoever runs the directory, and none can be made or
    revoked over the API.</p>
    <h2 id="errors">Errors</h2>
    <p>A request that fails answers with its status and <code>{"error": "…"}</code>:
    <code>401</code> no token or an unknown one, <code>403</code> a token without the access,
    <code>404</code> not listed.</p>
    <h2 id="ids">Ids</h2>
    <p>A feed’s <code>id</code> is the first 16 hex digits of the SHA-256 of its address with the
    scheme and host in lower case and no default port or fragment, so every server arrives at the
    same one. Descriptions are the publisher’s own HTML, unsanitized: sanitize them before you
    show them.</p>`,

 <h1>The directory</h1>
    <p>The directory gathers the public podcasts that iPX servers' listeners follow, and how many follow each. It never holds a file and never learns who listens.</p>
    <h2>Browsing it</h2>
    <p>Anyone can browse <a href="https://directory.ipxreader.app">directory.ipxreader.app</a> without signing in: the most followed, the categories, everything A to Z, and a page for each podcast with its latest episodes and its address, to subscribe to in any podcast app.</p>
    <h2>Connecting your iPX</h2>
    <p>In iPX, an admin opens Admin, Directory and enters the directory's address, <code>https://directory.ipxreader.app</code>, and the token its operator gave your server. Everyone on your server then has the Directory at the top of their list, and subscribes from it in one click.</p>
    <p>Turn on sharing to add your server's podcasts to it. iPX sends only the podcasts' addresses and how many people on your server follow each, never who. It leaves out anything that looks private: a podcast someone marked Private, one with a login or a key in its address, and paid feeds such as Patreon's.</p>
    <h2>Its API</h2>
    <p>Anything the pages show, a program can read through the directory's API with a token: see the <a href="/docs/api/directory/">ipx-directory API reference</a>.</p>
    <h2>Running your own</h2>
    <p>The directory is in the same repository. Build it, give it a database (Postgres or SQLite) and a config file, and make a token for each server that will use it:</p>
 <pre><code>docker build -f Dockerfile.directory -t ipx-directory .</code></pre>
 <pre><code>services:
  ipx-directory:
    image: ipx-directory
    container_name: ipx-directory
    restart: unless-stopped
    environment:
      DIRECTORY_DATABASE_URL: "postgres://ipx_directory:password@db-host:5432/ipx_directory"
    ports:
      - "8100:8100"
    volumes:
      - ./directory:/config:ro   # directory.toml</code></pre>
 <pre><code># directory/directory.toml
 bind = "0.0.0.0:8100"
 database_url_env = "DIRECTORY_DATABASE_URL"</code></pre>
 <pre><code>docker exec ipx-directory ipx-directory token new my-server --access rw</code></pre>
    <p>That prints the token, to give to the server, and the lines to add to <code>directory.toml</code>, which keeps only its SHA-256. The directory reads the file again within a minute, so adding or revoking a token needs no restart. It checks each podcast every twelve hours.</p>

 <h1>Install ipx and ipx-web</h1>
 <p class="lede">iPX is two containers: <strong>ipx</strong>, which checks your podcasts, downloads them and answers the API, and <strong>ipx-web</strong>, which serves the page and passes the API on to ipx.</p>
    <p>You need Docker with Compose. There are no published images yet, so you build both from the source:</p>
 <pre><code>git clone https://git.sdf1.net/rays/ipx.git
 cd ipx
 docker build -t ipx .
 docker build -f Dockerfile.web -t ipx-web .</code></pre>
    <p>The repository has a sample <code>docker-compose.yml</code> that runs both, with the database in SQLite and everything ipx keeps in three folders beside the file:</p>
 <pre><code>services:
  ipx:
    image: ipx
    container_name: ipx
    restart: unless-stopped
    environment:
      PUID: "99"          # who owns the files it writes
      PGID: "100"
      TZ: "UTC"
    ports:
      - "6881:6881/tcp"   # BitTorrent
      - "6881:6881/udp"
    volumes:
      - ./config:/config  # config.toml, written on first start
      - ./data:/data      # the database
      - ./downloads:/downloads
  ipx-web:
    image: ipx-web
    container_name: ipx-web
    restart: unless-stopped
    environment:
      IPX_UPSTREAM: "ipx:8099"
    ports:
      - "8099:8080"       # the page
    depends_on:
      - ipx</code></pre>
 <pre><code>docker compose up -d</code></pre>
    <p>ipx has no port of its own: everything reaches it through ipx-web, on port 8099. Open <code>http://&lt;your server&gt;:8099</code> and sign in as <strong>admin</strong> with the password <strong>ipodderx</strong>, then change it:</p>
 <pre><code>echo -n 'a good password' | docker exec -i ipx ipx user passwd admin</code></pre>
    <p>The password is read from what you pipe in, so it stays out of your shell's history.</p>
    <h2>Adding people</h2>
    <p>An admin adds people in Admin, Accounts, or from the command line:</p>
 <pre><code>echo -n 'their password' | docker exec -i ipx ipx user add sam</code></pre>
    <p>Each person starts with no podcasts and subscribes to their own. Two people subscribing to the same show cost nothing extra: it is fetched once and each file is kept once.</p>
    <h2>Settings</h2>
    <p>How often podcasts are checked, how much disk to use, how many new episodes to download and the rest are in Admin on the page, and take effect straight away. <code>/config/config.toml</code> holds only what ipx needs before it can read its database: where downloads go, BitTorrent, and who gets in.</p>
    <div class="scroll"><table>
      <thead><tr><th>Environment variable</th><th>What it does</th></tr></thead>
      <tbody>
        <tr><td><code>IPX_DATABASE_URL</code></td><td>A <code>postgres://user:password@host:5432/database</code> address, to keep everything in Postgres instead of SQLite</td></tr>
        <tr><td><code>PUID</code>, <code>PGID</code></td><td>The user and group that own the files ipx writes</td></tr>
        <tr><td><code>IPX_LOG_FORMAT</code></td><td><code>json</code> logs one JSON object a line, for Loki and the like</td></tr>
        <tr><td><code>OTEL_EXPORTER_OTLP_ENDPOINT</code></td><td>Sends traces of requests, checks and downloads to an OpenTelemetry collector; set <code>WEB_TRACING=on</code> on ipx-web too</td></tr>
        <tr><td><code>IPX_UPSTREAM</code></td><td>On ipx-web: where ipx is, <code>ipx:8099</code> by default</td></tr>
      </tbody>
    </table></div>
    <h2>Reaching it from outside</h2>
    <p>The page is plain HTTP. If anyone will reach it from outside your network, put HTTPS in front of it: a reverse proxy you already run, or a Cloudflare tunnel. People can then sign in through Cloudflare Access or Authentik instead of a password; <a href="https://git.sdf1.net/rays/ipx/src/branch/main/docs/sso.md">single sign-on</a> says how.</p>
    <h2>Updating</h2>
 <pre><code>git pull
 docker build -t ipx .
 docker build -f Dockerfile.web -t ipx-web .
 docker compose up -d</code></pre>
    <p>Your podcasts, accounts and downloads are in the three folders and are kept.</p>

 # Changelog: ipx-web
 The page, and the container that serves it (Caddy). ipx's changelog is
 [crates/ipx/CHANGELOG.md](../crates/ipx/CHANGELOG.md), which was the page's too until 0.12.0, and the
 directory's [crates/directory/CHANGELOG.md](../crates/directory/CHANGELOG.md).
 Its version is in `package.json`, and a release is tagged `web-vX.Y.Z`.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 ## [Unreleased]
 ## [1.1.0] - 2026-10-16
 ### Added
 - Signals pick what matters out of the noise of every feed you subscribe to: New signal takes a name, the words to listen for and, if those are not enough, a sentence saying what you mean, and its page lists the items from your feeds that are about it, read and unread as in their own feeds. Settings takes your TypeSafe key, which Signals need, and a Signal without one links to typesafe.ai to get one and to the key's place in Settings (#254, #266). They are kept in a Signals folder first in the feed list, under All Subscriptions, closed or open as an OPML is, with its own page listing them and a + there for a new one (#255, #256, #265). Each can have an icon of its own, searched for among all of Font Awesome Free, in place of its initials (#261), or one picked for it with Auto, which a Signal made without an icon gets by itself; each Signal's row counts its items and unread as a feed's does (#263).
 - A list opens at once when you have seen it before or the page fetched it ahead: All Subscriptions and the feeds with something unread are fetched when the page loads, and a feed or filter as the pointer or a finger reaches it, then refreshed behind once shown. A list that has to be waited for shows a spinner instead of nothing (#247). Currently Listening and the Directory's front page are fetched ahead the same way and open at once (#248).
 ### Changed
 - The page reports how long each list you open takes to show, from the click to the list drawn, for the dashboard (#246).
 - The page's files are compressed once when built, brotli at its strongest and gzip, and sent in place of the files: the script 30 KB where it was 37, the stylesheet 11 where it was 14. Traces go to the collector compressed (#253).
 - The page and the API's answers are sent compressed, zstd or gzip, which the feed list and item lists, over 100 KB each, were not; live updates and audio are not compressed (#239).
 ## [1.0.2] - 2026-10-15
 ### Fixed
 - The refresh buttons turn from the moment they are pressed until the scan they asked for has finished, smoothly, instead of jerking back upright between one feed and the next (#231, #233).
 - A feed's unread count stays put while a scan checks it quickly; the spinner takes its place only when a check takes a moment (#232).
 ### Security
 - The ipx-web image no longer carries curl, which Caddy's base image shipped and nothing used: 8.22.0 there is affected by CVE-2026-92392 (#237).
 ## [1.0.1] - 2026-10-13
 ### Fixed
 - A live update or a list refresh that fails because the network is gone (a laptop asleep) is no longer reported as an error, an error page from Cloudflare no longer becomes a request's message, and requests a minute or more after a tap start a trace of their own instead of joining that tap's (#219).
 ## [1.0.0] - 2026-10-12
 ### Added
 - With a directory token that may administer it, an admin has Check now and Remove from the directory on a Directory feed's page, and Servers and Blocked lists in Admin, Directory (#206).
 - The page has a version of its own, which the logo's tooltip shows beside ipx's (#207).
 - The page is served by its own container, ipx-web (Caddy), which passes the API to ipx on the same address, so a change to the page deploys without rebuilding ipx (#203).
 - Admin, Directory sets the directory's address and this server's token, and whether to share, and says how the last share went (#205).
 - A feed's settings have a Private switch, which keeps it out of the directory; on and locked for a feed whose address or login shows it is private (#205).
 - ipx-web logs one line a request, without the request's headers or a sign-in token in the address (#210).
 - ipx-web sends a trace span for each request when `WEB_TRACING=on`, continuing the page's trace into ipx (#213).
 ### Changed
 - The Directory says when no directory is set up, and its counts are of everyone on every sharing server (#205).
 - Add a feed no longer asks for a folder; a feed's folder is its title (#201).
 ### Fixed
 - On a phone, the Subscribe button on a Directory feed's page is full size again, not squashed to a sliver (#212).
