Opening the c50 edition threw `campaign.legacyStorageKeys is not iterable`
and left the board blank — the header still drew, so the level set looked
loaded. Every other edition carries the array; the hand-written c50 entry
did not, and 197 passing tests had nothing to say about it, because nothing
tested the registration itself.
The test now walks every edition and asserts the shape app.js relies on,
including that the chapter list can actually hold the levels. It fails on the
entry as it shipped.
The task board was reading levels/prototypes/d5.json while the campaign sat in
levels/campaign-50.json, so it showed "候选关卡 18 / 50" with fifty levels
built. It reads the shipping set when there is one.

The chain locks all four of its pieces at the opening by construction, and the
pieces grown around it are mostly locked too, so a level built from it hands a
player two rim pieces and a third of a second of animation before any thinking
starts. Measured across the 235-level pool: median two tappable pieces at the
opening, and the best departure available plays for 0.57s.
Growth now reserves a couple of slots for showcase pieces — tappable at the
opening, with a route long enough to read as a journey and short enough to stay
under the animation ceiling. Median opening choices go 2 to 3 and the best
opening show 0.72s to 1.12s, without shortcutting the lock: each candidate is
still put through the solver.
Rotation quota is gone from the board. Turning is free and it is what the game
is about, so depth is grown rather than capped; what is gated is whether each
turn pays out, whether pieces swing between hopeless and trivial, and whether
there is a show up front.

The chain built its own worst moment: hero and tail deadlock at orientations 0
and +2 and open only at +1, with +3/+4/+5 left entirely to chance. That is why
some levels released at exactly one of six orientations, and why every model
kept writing "I don't know which way to turn" — at +2 one direction was right
and the other five were dead ends.
createDeepLock now traces candidates at all six orientations and requires the
tail to also release at +3, certified with the real swept tracer. A player
stuck at +2 turns either way and something moves. Measured by the rule bot
over the regenerated set: blind rotations, wrong-way turns and extra rotations
all go to zero, from 1.17 / 0.44 / 1.22 per level. Endgame orientation counts
shift from {1:4, 2:10, 3:4} to {2:3, 3:13, 4:1}.
It costs yield: switchback r3 and crossing r3 now produce nothing, and the set
comes out at 17 levels rather than 18. The test witnesses moved with it — a
witness is whichever seed still satisfies the construction, so they are
re-derived from the sweep rather than pinned.
docs/level-board.html is the task board for getting to 50 levels. Task state is
in bench/board.json; every number on the page — candidate count, rotation
quota, blind turns, monkey actions-per-piece, the agent batches — is measured
from the level set and the run archive at build time.
