02 — Sprint Calendar (S1 → S26)

Two-week sprints. Twenty-six of them across 52 weeks. Four are reserved as buffer. Twenty-two carry deliverables. Every sprint has: a phase, a single named deliverable, a reading load, and a lab-notebook entry expectation.

Anchor date: S1 starts Monday July 6, 2026. Adjust the calendar column ±1 week if your real start differs.

Format: Weeks (dates) · Phase · Deliverable · Reading · Lab entry

Sprint Discipline Reminders

  1. Every sprint has ONE deliverable. Not three. Not “and also.” One. See ../13_discipline/01_sprint_cadence.md.

  2. Sunday evening = retro. Log what shipped, what slipped, what surprised you.

  3. If a sprint slips by >1 week, use the next buffer. Don’t cascade-compress.

  4. Buffer weeks are not sprint weeks. Do not populate them retroactively.

  5. Lab notebook: 3+ entries per week. Predicted number → measured → gap explanation. This is the meta-skill.

  6. Read-code 30 min/day. Even during buffer weeks. It’s habit, not sprint work.


Sprint Slippage Log Template

Copy into your lab notebook when a sprint slips:

Sprint: S<n>
Original deliverable: <one line>
What shipped: <one line>
What slipped and why: <one line, blameless>
Recovery plan: <one line>
Next sprint number: <n+1> (unchanged) OR sprint counter reset because <life event>

The One Sentence

Twenty-two deliveries, four rests, one year. The gate is Sprint 17-18 (M9). Everything else is negotiable.
