feat(sway): make idle policy depend on AC vs battery - #17
Merged
Conversation
Lock at 300s in both states, but only auto-suspend on battery — a plugged-in machine sitting idle should never fall asleep on its own. swayidle has no concept of power source, so scripts/idle.sh owns the decision: it polls AC/online and restarts swayidle with the right timeout chain when it changes, defaulting to the AC (no-suspend) branch if that read ever fails. Documents the design in PLAYBOOK.md §9.26 and adds the process-hygiene check (idle.sh + swayidle both pinned at 1) to the troubleshooting table, verification sweep, and CLAUDE.md gotchas.

[ -r "$AC" ] succeeding didn't guarantee the following cat succeeded -- a transient read failure in that gap fell through to the battery (auto-suspend) branch, the opposite of the documented fail-safe. One read, default to AC unless it explicitly says "0".
sway dispatches an exec line by two routes. At a reload the config is already active and the line reaches `sh -c` whole; at startup it is deferred into a queue and replayed through the parser `swaymsg` uses, which splits a command string on `;`. Both `exec_always pkill -x X; X` lines therefore ran only their pkill at login, the remaining segments rejected as unknown sway commands. So the machine booted with no swayidle at all -- no idle lock, ever -- and `pgrep -xc swayidle` returned 1 the moment anyone ran `swaymsg reload` to check, which is why this branch's own verification never saw it. kanshi had been broken identically for as long as its line existed; a reload always repaired it. Wrap both in `sh -c '...'` so sway receives one command and the inner shell owns the `;`. `exec` on the last segment drops the wrapper shell and leaves the daemon's own name in `comm`, so `pkill -x <name>` still matches it. check_sway_exec.py asserts the invariant across every exec line rather than the two that were found broken, and was verified to fail on the pre-fix tree. sway --validate cannot catch this: at validate time the line is a syntactically perfect `exec`.

`partition(" ")` splits on a literal space only, so `exec_always<TAB>pkill
-x a; a` -- which `sway --validate` accepts -- left `head` as
`exec_always\tpkill`, missed KEYWORDS, and was skipped in silence. The guard
returned 0 on precisely the bug it exists to catch. Split on whitespace
instead.
Adds the negative assertion it should have shipped with: theme_test.sh now
proves the checker fires on both separators sway accepts and stays quiet on
the wrapped form. Confirmed the pre-fix checker returns 0 on the tab
spelling and the fixed one returns 1, so the case is not vacuous.
Same failure mode as check_hex.py being blind to bare RRGGBBAA for months:
a green assertion the guard cannot see is worse than no assertion.

The comment opened on the check_hex.py precedent, which reads as though the test were about hex. Lead with the failure this one detects -- an unquoted `;` on an exec line, in both separators sway accepts -- and keep check_hex.py where it belongs, as the named precedent for the repo rule being satisfied.
