The decision ladders are first-match-wins: the matching branch calls
sys.exit(0), so no later condition is ever evaluated or recorded. That made
DECISION lock=no reason=early_bird_window_active
ambiguous in the one way that matters -- it cannot say whether the workout was
also already done, or the weekly minimum already met. Reading it, the 08:30
re-check looks like it is about to lock a machine that has nothing left to
prove, and the only way to find out was to re-derive the ladder by hand.
Keep the acting reason exactly as it was: it is the branch that actually
controlled behaviour, and it stays a stable grep-able slug that can be counted
across runs. Add the conditions that also held as an "also=" extra, which
as_line() already renders as key=value. A decision with a single reason still
renders the line it always did, so the common case needs no new format.
Only side-effect-free predicates are collected. _try_auto_upgrade_* writes log
entries and does ADB/network work, and _save_early_bird_pending writes state;
running either to produce a log line would turn a reporting change into a
state mutation in the enforcer. Verified that annotating leaves log.json and
early_bird_pending.json byte-identical.

screen-locker
Tkinter/systemd screen locker with workout tracking, sick-day management, and wake-alarm integration. It enforces a workout cadence by locking the screen until a RunnerUp-verified (or explicitly justified) workout is logged.
MCP server (Claude Code integration)
screen-locker exposes a read-only MCP server (screen_locker._mcp) so
Claude Code and its subagents can query workout compliance and the
lock-decision state through typed tools — without shelling out to the
screen-locker-status CLI or opening the Tk window.
- Read-only tools:
get_status(full status snapshot),get_summary(one-line i3blocks summary +ok/warn/lockstate word),explain_lock(why the screen is / isn't locked right now),get_flags(the individual boolean lock-decision predicates for today). - There are no write/action tools, by design. Nothing here logs a workout or mutates state — workouts are logged only from RunnerUp-verified TCX data, never from a caller's claim. No tool exposes the sync token or any HMAC key.
The mcp SDK is an optional dependency (pip install -e '.[mcp]'), kept out of
the CLI/systemd system-python path. One-time setup of the dedicated venv that
Claude Code spawns:
./scripts/setup_mcp.sh
Registration lives in the checked-in .mcp.json (project scope).
Restart Claude Code in this repo and approve the project MCP-server prompt for it
to load. Verify with claude mcp list.
