INTERACTIVE MATCHUP GUIDE
- Compare all 91 pairings of 13 offensive calls and seven defenses.
- Select either call to inspect the offense's formation and both play tips.
- View ratings from each side, ranked offensive options against a coverage
and ranked defensive answers to a play. Equal ratings keep playbook order.
- Positive ratings favor the named side. They are base matchup ratings,
not yardage forecasts or success percentages; other game factors matter.
- Special teams, clock plays and trick plays are outside the comparison.
- Save or remove the selected calls in the existing shared favorites.
The call sheet refreshes without calling a play or changing game state.

game where appropriate. Tab navigation stays inside the guide.

through the existing Retry save control.

practice notebook version 1 are unchanged. No additional storage key.

identical, including its random sequence.

resolved plays, elapsed time and Nebraska timeouts remaining.

objectives and both teams' timeouts. You choose the calls again.

replay always uses the current version.

MATCHING-SETUP COMPARISONS
- Attempt reviews show objectives met out of matching retained attempts,
distinct seeds and fewest resolved plays in a successful attempt.
- Matching requires the same game version, drill, opponent, difficulty,
weather and every custom setting. Seeds may differ.
- Repeated seeds count as separate attempts. Resets and unfinished drills
are excluded, and rendering a completed review never adds duplicates.
- Comparisons describe retained practice history, not win probabilities.

- Uses a separate tronsoft_huskers_2026_practice storage key. Season save
key, format 1.6, internal version 7 and review version 1 are unchanged.

and unfinished attempts still remain only in the current page session.
- Failed writes keep results in memory and offer Retry notebook save.

explicitly confirms clearing them; new results remain in memory.
- Clear notebook requires confirmation and commits before clearing memory.
Season progress, favorites, trophies and game reviews are untouched.

VALIDATION
- 149 regression checks pass, including 15 notebook storage/engine checks
and seven added interface-handler checks for recording, replay, filters,
save retry, clearing, legacy-data protection and HTML escaping.
- Preset and custom setup replay restores the original initial state.
- Notebook reads/writes/clearing leave season state and its subsequent
random sequence unchanged.
- A retained 30-attempt sample uses about 18 KiB; a full-length 14-game
season remains about 366 KiB, within the 1 MiB storage estimate.
- UI handlers tested with DOM stubs; browser visual testing unavailable.

untimed conversion or overtime transition stays in its actual period.

read-only inspection, HTML escaping and live/archive interface handlers.

from optional scoring metadata; every recorded score reconciles.

position, recorded yards per drive, TDs, FGs, giveaways and downs.

team's frame. Punts and field goals record their actual kick spot.

ambiguous spots show only their starting position and Unavailable.

interface events and unchanged results while reading reports.
