The loop-recovery helper's notice (/run/fly/wd/recovery-notice.json,
FLY_RECOVERY_NOTICE) is served by serve.mjs at /recovery-notice.json and
polled once a second by the page, independent of flysim. Countdown shows a
Game Boy text box over the bottom of the game; acting covers the game while
flysim is down; done/failed show briefly. Stale, malformed or oversized
notices are ignored and helper strings are clipped to a closed charset.
Adds ?recovery=, __stage.recovery(), the recovery-notice dev tool, unit
tests (model, poller, serve.mjs route) and an e2e spec.
Restart flysim, then reset to the current rung's milestone, then to the
archive below the best rung (never lower), one step per confirmed trap
that outlives the previous one. Two resets a day, three-hour restarts
once they are spent; the ladder starts over at a new best rung or after
six quiet hours. State and history live in the unit's StateDirectory so
a reboot does not forget where the ladder stood.
A router model list confirms each step; a 'not stuck' answer delays it
at most three probes and no answer leaves the watchdog to decide alone.
Each step is announced 60 s ahead in /run/fly/wd/recovery-notice.json
for the stage's recovery splash.
fly-loop-reset is the one new root surface (a sudoers line); 05-deploy
now converges config/fly-sudoers so a release can add it.
flyedge.service runs /opt/fly/current/fly-edge After= and Requires=
flysim.service, with its metrics on loopback :9102 and a
ConditionPathExists so a release without the binary leaves it inactive. It is
in no target and 07-enable.sh does not enable it; the header has the switch
and the way back.
build-flysim.sh also builds fly-edge beside the flysim binary and
package-release.sh ships it when present. 05-deploy.sh writes
FLY_FEED_VIA (default direct) into fly.env, flysim.service names
FLY_BUS_DIR=/run/fly/bus and tmpfiles creates it. Watchdog check 2 reads the
feed counters from whoever serves the feed: flyedge when fly.env says bus.
lint.sh holds all of that, and drives check 2's choice against a fixture.
