Re-arm the locker, and make a disarmed enforcer impossible to miss
The screen locker stopped locking on 2026-08-04 and nobody could tell. Not a
logic bug: every predicate worked the whole time. systemd logged

  timers.target: Found ordering cycle: early-bird-workout-check.timer/start
    after graphical-session.target/start after basic.target/start after
    timers.target/start - after early-bird-workout-check.timer
  timers.target: Job early-bird-workout-check.timer/start deleted to break
    ordering cycle starting with timers.target/start

and left the timer disabled. A timer that is WantedBy=timers.target must not be
ordered After= a target that itself comes after timers.target; systemd resolves
that loop by deleting the job, which is an absence, and absences page nobody.

That timer is the ONLY thing that closes the early-bird window. Each morning a
run inside the window banked early_bird_pending.json, logged "will re-check at
08:30", and exited 0. The re-check never came, so the marker stood all day,
every day, for thirteen days.

It stayed invisible because logging.basicConfig was called only in the
--sync-only branch, never for --production -- the mode systemd actually runs.
Journal proof: zero INFO lines from workout-locker.service since June. Every
early exit logged at INFO into a logger with no handler. Meanwhile the healthy
15-minute sync kept the system looking alive.

The 2026-08-15 Python split is NOT implicated: it was pure code motion, and
basicConfig already sat in that branch before it.

Fixes:

* Drop the After= that closes the cycle; Persistent=true so a machine asleep at
  08:30 still re-checks after resume.
* Add workout-locker.timer (*:00,30). The service is WantedBy=
  graphical-session.target, i.e. one decision per login, so the 08-16 -> 08-17
  day and ISO-week rollover inside one long session was never re-evaluated.
* arm.sh: install units, enable timers, verify -- one command, because
  re-arming was a four-command sequence that was easy to half-do, and
  `systemctl enable` returns 0 while systemd deletes the timer job.
* check_enforcement_armed.py asks systemd what it actually scheduled (enabled
  AND has a next trigger) and fails loudly otherwise. Wired as ExecStartPost on
  workout-sync.service, so a disarmed locker marks that unit failed every 15
  minutes instead of scrolling past. install_systemd.sh now fails on it too.

Logging (the reason this went unnoticed, so treated as a defect in its own
right):

* basicConfig for every mode, never one branch.
* Every enforcement-abandoning exit records a decision instead of an invisible
  INFO: one greppable line -- DECISION lock=no reason=early_bird_window_active
  weekly=0/5 -- at WARNING, since per CLAUDE.md an INFO explanation of a
  non-action is a silent failure with extra steps. The enforced case is logged
  too: "no line at all" was the outage's whole signature.
* A durable JSONL trail outside the repo (~/.local/share/screen_locker/), so
  "when did this last actually enforce?" survives journal rotation. --status
  and --sync-only record lock=n/a; "did not decide" must never look like
  "decided not to lock".
* check_silent_failures.py now also catches sys.exit(0) that explains nothing.
  Verified both directions: it flags 3/3 exits in the pre-fix _auto_upgrade.py
  and passes the repo clean.

Sync noise: four records replayed as WARNINGs every cycle (~384/day), which is
how the actionable lines got tuned out. manual_workout:2026-08-15 is an empty
stub ({date, kind, type}) -- no workout to recover, and that day's credit was
already counted under a different sync_record_id, so no credit was ever lost.
The three "collided" records are dedup working. Both now report at info; a
WARNING from this logger again means something real. 4 -> 0 per cycle.

Verified on the live system: the periodic timer fired at 16:45 and the journal
shows `DECISION lock=no reason=scheduled_skip_day weekly=0/5` -- the line that
did not exist for thirteen days. Both timers report enabled and scheduled, and
no ordering cycle recurs. Today is a scheduled skip so the machine was not
locked mid-session; enforcement resumes tomorrow 08:30. 1007 tests, 100%
coverage, all hooks green.

hooks:
# Two hooks, because the three checks below are not defects in a test
# suite -- they are how pytest and unit-testing private mixins work --
# while in SOURCE they are real findings that must still fail:
# protected-access tests drive private mixin methods directly; those
# methods ARE the unit under test (ruff already
# exempts the same thing via SLF001 for tests).
# unused-argument pytest fixtures must be REQUESTED in the signature
# to take effect but are never referenced in the body.
# duplicate-code near-identical `with patch(...)` preambles; a test
# should read top-to-bottom without chasing a fixture.
# Splitting also removes the old failure mode where the score depended on
# what else happened to be staged alongside. See
# todo_fix_pylint_10_prompt.md for raising both to a hard 10.00.
