CHANGELOG
=============================================================
TAK versioning mirrors AR versioning. The algorithm is identical between the two
tools; TAK is rebuilt from the AR file with branding swapped.

TAK-2.26 / AR-2.26 (2026-10-18) — full algorithm audit and rebuild
Verified with an automated harness (13 scenario plans, 5K to 100-mile, road and
trail, miles and km, Friday/Saturday/Monday/Sunday races) plus a headless UI test
of the complete form → generate → unit toggle → print → edit flow, run against
this TAK file as well as the AR file.

ALGORITHM FIXES
- Short-race long runs fixed: the 95%-of-race-distance cap now applies only from
  25K upward. 5K/10K/half long runs progress properly (5K peaks 5/7/9 mi,
  10K 6/8/10, half 10/12/14 by level).
- Easy runs capped at 75% of the week's long run (max 12 mi / 19 km); a plan that
  cannot hold the runner's volume on the chosen days says so in the summary.
- 10–15% rule enforced against realized weekly volume; step-backs at 75%; taper
  as a fraction of the peak actually reached; continuous phase curve.
- No step-backs inside short Peak blocks; long run −20% on step-back weeks; trail
  hill day becomes a steady Hilly Run on step-back weeks.
- Peak-volume floors for half (22 mi) and marathon (35 mi); long run start point
  respects the runner's base.
- Weekly elevation equals the sum of the day cells (normalized weights,
  gradient caps, largest-remainder rounding to 100). Elevation peaks in the last
  pre-taper week and tapers with volume.
- Final seven days handled by calendar day: 1–2 out rest, 3–6 out shakeout, race
  on the right day; last taper long run relocates to six days out for early-week
  races (fixes Friday/Monday races).
- Run/walk only for beginners under ~16 km (10 mi) per week.
- Goal time "1:45" for a half read as 1h45; invalid paces rejected with a message;
  goal time only used when Time Goal is selected.
- Pace model per distance (threshold, 10K reps, race pace); tempo progresses from
  threshold toward race pace; hill repeats sized as "6 × ~80 m hill"; Base and
  taper hill days are steady hilly runs.

TEXT / UNITS
- Interval reps in km for km plans; tempo parts add up to the badge distance;
  summary peak is the real peak (km double-conversion fixed); race name used on
  race day; trail time-goal wording; punctuation fixes; "Wk 9" chips.

UI
- Typing distance/mileage no longer re-renders the form (focus kept); unit toggle
  regenerates a shown plan in the new unit; dates on screen day cards; print
  restore via afterprint; calendar opens on race month; validation messages;
  day of week on race date card and print stats.

TAK-SPECIFIC
- Header version label corrected (file previously said TAK-2.24 while carrying
  v2.25 logic). Branding, favicon logo (36px square) and Ghost CSS overrides
  carried over unchanged.

TAK-2.25 / AR-2.25 (2026-05-04)  Plan start anchored on Monday of race week.
TAK-2.24 / AR-2.24 (2026-05-04)  nextMonday() fix; print cell dates.
TAK-2.23 / AR-2.23 (2026-04-23)  0.5 snapping; print descriptions; contrast.
TAK-2.22 / AR-2.22 (2026-04-23)  Race Name field.
TAK-2.21 / AR-2.21 (2026-04-23)  Race week built around race day of week.
TAK-2.20 / AR-2.20 (2026-04-23)  Gradient caps; file renamed to -v2.
TAK-2.19 … TAK-2.17 (2026-04-23)  Elevation and state fixes.
TAK-1.0 (2026-03-30)  Initial TAK version based on AR v2.16.
