fix: the watchdog stops burying the desktop in popups nobody asked for
Three defects, and the loudest one was self-inflicted.

test_watchdog.sh stubbed only curl and docker, so notify-send resolved to
the real binary and the suite fired a dozen genuine critical popups every
run -- from a pre-commit hook. On 2026-08-31 the timer emitted zero
messages and the desktop still collected 297, all of them from committing.
The stubs now live in the harness, and the suite asserts the counts.

give_up() had no once-only flag, so a six-hour window announced itself
every two minutes -- up to 180 times -- while its own text said "no
further restarts". A stamp in the state dir now gates the popup, and only
the popup: journald still gets every line, which is why the existing
stdout assertions are untouched.

alarm() hardcoded --urgency=critical, which xfce4-notifyd never expires,
and passed no replace id, so they stacked instead of superseding.
notify-send --print-id now feeds --replace-id from one slot. WATCHDOG_NOTIFY
picks how much reaches the desktop at all; it defaults to escalation, so
the routine restart/recovery pair is journald-only from here.

test_watchdog.sh crossed the 250-line cap, so the sandbox and the
assertions moved to test_watchdog_harness.sh, and the hook that runs the
suite now watches all three files.

# Copy to .env and fill in. Every value here is read by signal_bot/config.py.
# The bot refuses to start if any REQUIRED value is missing or blank.
# REQUIRED. The account signal-cli is linked to, in +E.164 form.
PHONE_NUMBER=
# OPTIONAL, and normally left empty. Comma-separated group ids.
#
# Empty means "every group this account is a member of", discovered at
# runtime: adding the bot to a group is then the whole procedure, with no
# edit here and no restart. That is safe when the bot has its OWN number,
# because such an account has no other chats.
#
# Set it when the bot runs as a LINKED DEVICE on a personal account, where
# it would otherwise see every group on that account. scripts/live_smoke.sh
# writes it for you in that case; scripts/register_bot.sh deliberately does
# not. Startup fails if a listed group is not one the bot has joined.
#
# Find the ids with: curl -s localhost:9922/v1/groups/$PHONE_NUMBER | jq
#
# Replies, rate limits and the daily tally are per group either way: a
# command is answered in the group that asked and nowhere else, so there is
# no send target to configure. GROUP_ID is still accepted as the one-group
# spelling; GROUP_ID_SEND was removed and now fails startup if set.
GROUP_IDS=
# Optional. The signal-cli-rest-api container. Point this at the fake server
# to run entirely offline. Default: http://localhost:9922
API_BASE_URL=
# Optional. Tally database. Survives restarts. Default: signal_bot.sqlite3
DATABASE_PATH=
# Optional. When the daily tally is posted. Default: 21:37
REPORT_HOUR=
REPORT_MINUTE=
# Optional. Per-user, per-command cooldown in seconds. Default: 10
COOLDOWN_SECONDS=
# Optional but recommended. Comma-separated +E.164 numbers -- or member
# UUIDs, which is how /v1/groups spells anybody the account has never
# messaged -- allowed to add this bot to a group.
#
# Empty means anyone who knows the number can pull the bot into a group and
# have it answer there. With it set, "add the bot" is still the whole setup
# for you, and a stranger's group is refused with one WARNING naming that
# group's members, so you can see exactly which string to add here.
TRUSTED_INVITERS=
# Optional. How long the bot may hear nothing at all -- no message, no
# receipt, no typing indicator -- before it probes /v1/devices to find out
# whether it has gone deaf. Three failed probes and /healthz turns 503.
# Default: 120. scripts/e2e.sh sets it to 0 to prove the gate really fires.
SILENCE_SECONDS=
# Optional. Image APIs. Overridden by scripts/e2e.sh to serve local fixtures.
CAT_API_URL=
DOG_API_URL=
GECKO_API_URL=
COMMONS_API_URL=
# Optional. Where !papież keeps the 267 papal portraits it has downloaded.
# Default: $CACHE_DIRECTORY/portraits under systemd (the unit sets
# CacheDirectory=signal-bot), otherwise $XDG_CACHE_HOME/signal-bot/portraits.
PORTRAIT_CACHE_DIR=
# Optional. Groups scripts/selftest.sh may make the bot post into. Empty by
# default, which makes POST /_selftest refuse everything -- Signal never
# delivers an account its own sends, so this is the only way to exercise a
# command without a second account, and it posts for real.
SELFTEST_GROUPS=
# Optional, and private. The album the per-person photo commands draw
# from: a directory holding people.json, tags.json and media/. Everything
# identifying lives in there and nothing about it is in this repository --
# see DOCS-photo-pack.md, and tool/tagger.py for how it gets filled in.
#
# Leave it empty and the bot looks in $STATE_DIRECTORY/pack (systemd) and
# then $XDG_DATA_HOME/signal-bot/pack. Not finding one is normal: the
# commands simply do not exist. Naming one that is not there, or one whose
# manifest cannot be honoured, fails startup rather than every command.
PHOTO_PACK_DIR=
# Optional. Where the /healthz readiness probe binds.
# Default: 127.0.0.1:8137 -- deliberately not 8000, which unrelated dev
# servers grab, and below the ephemeral range so the kernel cannot take it.
BIND_HOST=
BIND_PORT=
# ---------------------------------------------------------------------------
# scripts/signal_api_watchdog.sh -- the two-minute timer that restarts the
# container when signal-cli can no longer reach Signal. Every value here is
# optional; the defaults are what the timer has always used.
# ---------------------------------------------------------------------------
# What reaches the DESKTOP. journald gets every message either way, twice --
# `journalctl --user -t signal-api-watchdog` and `-u signal-api-watchdog`.
# escalation only the give-up message pops, and only once per window
# always every transition pops, reusing one replaceable slot
# never nothing pops
# Default: escalation. The routine restart/recovery pair is the noise this
# exists to stop -- it used to pop on every firing, with critical urgency and
# no replace id, so one outage left a screen of boxes to dismiss by hand.
WATCHDOG_NOTIFY=
# How long a popup stays up, in milliseconds. Default: 20000.
WATCHDOG_NOTIFY_EXPIRE_MS=
# Consecutive failed probes before the container is restarted. Default: 2.
FAILURES_BEFORE_RESTART=
# Restarts allowed inside RESTART_WINDOW before it gives up and escalates
# instead. A deregistered account is not fixable by restarting, and a
# forever-loop would hide that. Defaults: 3 restarts, 21600 seconds (6h).
MAX_RESTARTS=
RESTART_WINDOW=
# Seconds to wait after a restart before deciding whether it helped, and the
# per-probe curl timeout. Defaults: 45 and 15.
