The enforce loop now waits on an inotify watch of log.json's directory (_file_wake, ctypes, no new dependency) instead of a plain sleep, so a credited workout moves the gaming budget within the tick. Earner answers (workout, LeetCode, reading) are memoised with the source file's (inode, mtime_ns, size) stamp, so a rewritten file re-asks at once instead of after the 60 s TTL. Any inotify setup or read failure warns and falls back to the plain sleep; the stamp still catches the change next tick. Tests: conftest stubs the wake factory and points workout_log_path at a tmp path, so no test ever watches the real screen-locker tree.

"""Whether a paper-book reading session was credited today, worth an hour.
|
|
|
|
book-guard (``~/src/book-guard``) publishes reading through its signed ledger,
|
|
the same shape as leetcode-guard's, and screen-locker reads the same fact for a
|
|
shutdown hour. Shaped like :mod:`steam_backlog_enforcer._leetcode_bonus` where
|
|
it matters:
|
|
|
|
**Fail closed.** Bad JSON, a missing entries array or an unreadable key yields
|
|
``None`` -- no bonus, logged at warning. Failing open would let the coupling be
|
|
defeated by deleting a file.
|
|
|
|
**Independent.** Read separately and summed by ``resolve_budget``; nothing here
|
|
can move the workout or LeetCode terms.
|
|
|
|
**One transport.** book-guard has no status server, so there is no fallback;
|
|
and no incident either -- until the first book is registered the ledger simply
|
|
does not exist, and that is not worth waking anyone about.
|
|
|
|
The contract (book-guard's ``_quiz.record_verdict``): only ``credit`` rows with
|
|
``detail["bonus"] == "1"`` count -- a passed quiz on a 20+ page, 20+ minute
|
|
session -- dated by ``detail["ended_at"]``, when the reading happened.
