focus_project

Time-boxed focus projects ("until Thursday I prepare for X"). The active project switches chosen gates off and defines a daily-minutes gate.

import focus_project as fp

fp.stands_down("leetcode", today)   # gate in leetcode|book|reading|tutor; never raises
fp.active(today)                    # Project | None
fp.status(today)                    # dict for i3bar / GUIs
fp.record_activity("timer", "start")

Data: $FOCUS_PROJECT_DATA or ~/.local/share/focus_project/ (projects.json, activity.jsonl). minutes.py is owned by the minutes/harvester agent. Time rules: minutes_for clips every interval at "now" (an event stamped ahead of the clock earns only once the clock reaches it); record_activity rejects a ts more than 120 s ahead (ValueError). Timer segments (start -> checkin ... -> stop) lapse after a 600 s gap; a tutor/heartbeat is a beat too (0.8.0: a graded check-in card extends the open segment, never opens one). end_project(id, day) rejects a past day (ValueError); today or later is fine. The harvester pays every project day of the last 31 days, so late-synced events for older days are credited (idempotent). Overtime carries over: own minutes past a day's target bank (max 60) and pay on the next project day; the bank never crosses the project's end. minutes_for(day) is the capped pay figure, status(day)["minutes"] the real count (121/120) with carried_in, carry_out, own_minutes, counted_minutes. Carry ledger rows: <project>-<YYYYMMDD>-carry (detail.carry), never over daily_minutes together with own rows. Edits only ratchet (0.7.0): update_project/apply_update(id, today=...) never lowers today's obligation. A lower daily_minutes/unlock_minutes, or a gate added to replaces, on a started project holds from TOMORROW (a history row ends today with the old values, replaces_on(day)/daily_on/unlock_on read it); a mixed edit defers as a whole. Raises, gates removed and edits to a project that has not started hold from today. apply_update(...).effective_from says which. end cannot be before today, so an edit never uncovers today. A NEW project starting today may replace gates and set any targets: it is a new obligation, not a reduction (but see the floor). Floor (0.7.1, coordinator decision for kuhy): daily_minutes >= 30 x replaced gates (min 30; book = reading), enforced on create and update (daily_floor(replaces)), so a day cannot be made cheap. Backed timer (0.10.0, days from BACKING_FROM = 2026-11-08): a timer span earns only if a same-project tutor/sql_drills/leetcode beat (or accepted submission) is in it, 5 min before it, or bridges it (beats <= 20 min apart). unbacked_minutes_for(day) / status()["unbacked_minutes"] show the rest. A beat backs only the spans it touches (the tutor chain makes a graded card back the whole stretch). Known gap: any coach turn backs. Open the work: python3 -m focus_project.open [--no-site] (tutor focus screen, work_url). Install: ./install.sh (stdlib only, editable user install for /usr/bin/python3).

Interview prep (kind="interview", 0.9): create_project(..., kind="interview", test_at=, invite_url=, trips=, weekend_answers=); end must be the test day. Budget: 30 min weekdays / 120 Sat-Sun (daily_on), exempt from daily_floor, unlock clamped. Milestones are generated, never stored: milestones(project, now) -> rules, trip_ask:<sat>, phone:<trip start>, mock, slot with states pending/done/missed/late_done/unknown. owed_lock(now) = earliest overdue uncompleted one (never on test day; wire it after focus-guard's sick/free-day stand-down). status(day) gains milestones and missed. Evidence is append-only (evidence/<id>.jsonl + copied files): record_evidence(id, milestone, kind, value, file=, now=) (file, tap, score, slot, slot_confirm, tutor's phone_check). add_trip / answer_weekend only get stricter (ValueError). run_checks(id) runs the phone source (reads the latest phone_check row) and latches changes; register_source swaps it.
