Clears 141 open SonarCloud issues on overall code. The quality gate was
already green (every condition is on NEW code), so this is accumulated
debt rather than a blocker -- but reliability sat at C on two bugs.

Reliability C -> A: phasic-dial and rolling-blocks constructed their
editor at module scope and dropped it (typescript:S1848). Both now use
the `export const page` holder the other three pages already had, which
makes the rule uniform across all five.

TypeScript/CSS: readonly fields, `.at(-1)`, optional chaining,
`.toSorted()`, `findLast`, and cognitive-complexity extractions in the
two `renderGrid`s, `computeMovableSet`, `isDeadlocked`, `boundarySteps`,
`hasEll`/`hasLongTee` and the bench/fuzz harnesses. `aStar.ts` takes an
options object instead of eight positional parameters. The rolling-blocks
brand purple moves to a `--rb-block` token darkened to #7a5cbe, which
lifts white-on-purple from 4.49:1 to 5.12:1 (AA needs 4.5:1).

C++: guarded the clang/MSVC-STL shim in the five rolling-blocks gtest TUs
and hoisted it into a shared ClangdCompat.h; if-init in both StateTable
probe loops; `using enum`; jthread and explicit captures in
ParallelCascade; the two DragSolver BFS worklists become
`while (head < queue.size())`, which is the correct remedy -- a range-for
there would be UB since the body push_backs while iterating. MemoryProbe
gets its platform include block hoisted to the top of all four copies,
and logic-grid's macro prefix corrected from MT_ to LG_.

Field-count groupings: BenchOptions 39 -> 12, DragSolverConfig 30 -> 14,
logic-grid Model 25 -> 18 via a `Walked` struct. Roughly 290 call sites.

Re-measured the two performance refusals from the July pass against a
±0.5% noise floor, bisected apart:
  - BitGrid DX/DY/DIRS -> std::array is now FREE (+0.1/-0.1/-0.5%). The
    July 3.4% does not reproduce; the toolchain moved (MSVC 14.44). Taken.
  - NodeKey heapData -> unique_ptr still costs +3.7% unit / +5.2% jam.
    Refused again, with the new numbers written into the comment.
A measured refusal is worth re-measuring after a compiler bump.

21 findings that survived a genuine fix attempt are marked resolved on
SonarCloud (4 false-positive, 17 accepted), each with what was tried and
why it failed recorded in CLION-INSPECTIONS.md.

Verified: typecheck, bun test (1812 pass / 0 fail), native Release build
with the clang-tidy gate live (6233/6233 ctest), build:wasm, and a
150-case fuzz:sm sweep matching the July baseline.

Darkening --rb-block to #7a5cbe for contrast invalidates the committed
frames, which are shot from the live pages. Rolling-blocks moves by one
byte -- the default editor has no blocks placed, so the new purple is not
actually in shot -- but the recapture was owed either way.

It also picks up a stale frame nobody had noticed: logic-grid still
showed the flat pre-v2 rule list, so the site has been advertising a UI
that has not existed since RULE_ROW became banded bands with folded
dark/light swatch pairs and the sized-family + controls.

The existing note only mentions the recapture under "adding a page", which
is how logic-grid's frame went stale: RULE_ROW became banded and nothing
re-shot it, so the live site advertised the pre-v2 flat rule list. Nothing
in CI compares the frames, so the rule has to live here.

📝 Walkthrough

Walkthrough

The PR reorganizes solver data and configuration across Logic Grid, Match Three, Rolling Blocks, and Shifting Mosaic. It also refactors search, rendering, memory probes, page initialization, tests, native tooling, and development documentation.

Changes

Logic Grid solver updates

Layer / File(s) Summary
Walked geometry model flow
src/pages/logic-grid-solver/a-star/Puzzle.h, Puzzle.cpp, Propagate.cpp, Verify.cpp, test/puzzle_test.cpp
Geometry clue indexes and objects now use Model::walked. Construction, propagation, verification, and tests use the nested collections.
Shape and outline helpers
src/pages/logic-grid-solver/shapeOutline.ts, verifyCore.ts, verifyPatterns.ts, clueEdits.ts
Boundary emission and pattern checks use extracted helpers. The exported Held callback type was added.

Match Three numeric cell types

Layer / File(s) Summary
Numeric cell contract
src/pages/match-three-solver/*, src/util/types.ts
Match Three APIs and fixtures now use numeric cell grids. MatchThreeCell was removed.
Validation and memory probes
test/match-three-solver/*, src/pages/match-three-solver/a-star/MemoryProbe.h
Tests use numeric cells and separate move-count assertions. Platform memory-probe handling was reorganized.

Rolling Blocks updates

Layer / File(s) Summary
Native solver and compatibility
src/pages/rolling-blocks-solver/a-star/*
State blocks use std::array, move guarantees receive static assertions, and test compatibility handling is centralized.
Board rendering and styling
src/pages/rolling-blocks-solver/board.ts, rollingBlocksSolver.css
Cell construction uses shared edge marking, and block colors use --rb-block.

Shifting Mosaic updates

Layer / File(s) Summary
Search contracts and storage
src/pages/shifting-mosaic-solver/a-star/aStar.ts, AStarSearch.cpp, BitGrid.h, StateTable.h
AStar uses typed options and extracted search helpers. Equality, direction tables, and state storage receive explicit type and container updates.
Grouped solver configuration
DragSolverConfig.h, BenchOptions.h, BenchOptions.cpp, BenchEngines.cpp, DragSolver*.cpp, main.cpp
Packing, jam, stop, path, limit, and generation settings move into nested structures. Consumers use the grouped fields.
Drag and cascade execution
DragSolver.cpp, DragSolver.h, ParallelCascade.h, wasm_bindings.cpp
Drag solving extracts reusable BFS and packing helpers. Cascade APIs use Board and Budget aggregates.
Editor and support utilities
board.ts, solutionView.ts, wasmBridge.ts, util/*, test/*
Rendering, stroke warnings, worker labels, benchmark output, fuzz output, and test helpers use extracted logic and modern array APIs.

Development documentation

Layer / File(s) Summary
Build and inspection guidance
CLAUDE.md, CLION-INSPECTIONS.md
Documentation records page-holder initialization, visual capture steps, native build commands, inspection workarounds, and reviewed findings.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🔴 Critical · up to 211d5

The changes currently contain a duplicate path declaration that prevents TypeScript compilation, so the PR should not merge until that declaration is removed and validation passes.

src/pages/phasic-dial-solver/button.ts (1)

2-9: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the turns array immutable at the API boundary.

Line 2 makes only the property reference readonly. The constructor stores the caller’s mutable array, and getTurns() returns the same mutable array. The configuration path passes entry.turns directly, so callers can still mutate Button state after construction.

Copy the input array and return a copy, or expose a readonly array without exposing the backing storage.

Proposed fix
-  private readonly turns: number[];
+  private readonly turns: readonly number[];

   constructor(turns: number[]) {
-    this.turns = turns;
+    this.turns = [...turns];
   }

   public getTurns() {
-    return this.turns;
+    return [...this.turns];
   }

Add braces to the if (beam) body.

The body is one statement that wraps across Lines 160-161. The next statement at Lines 162-163 assigns another cfg.jam.* field and aligns visually with it. Braces remove the risk that a later edit moves an assignment into or out of the conditional by accident.

Consider a named copy for the sequential budget.

The code mutates the same budget object that the parallel race used. The mutation is safe today because solveArmsParallel already returned. A separate seqBudget copy makes the two phases independent and prevents an accidental reuse of race settings if code is inserted between the phases.

♻️ Proposed change
-  budget.maxHeapBytes = seqHeapCap;
-  budget.totalMaxMs = seqTotalMs;
-  return solveArmsSequential(
-      board, budget, postProgress, /*cancel=*/nullptr, /*outcomes=*/nullptr,
-      [](const char *arm) { postPhase("sequential", arm); });
+  cascade::Budget seqBudget = budget;
+  seqBudget.maxHeapBytes = seqHeapCap;
+  seqBudget.totalMaxMs = seqTotalMs;
+  return solveArmsSequential(
+      board, seqBudget, postProgress, /*cancel=*/nullptr, /*outcomes=*/nullptr,
+      [](const char *arm) { postPhase("sequential", arm); });

This also lets budget stay const at its declaration on Line 234.

than guard a modulo the function never needed, the four scan orders are
now WALKED instead of sorted into place: a flat index is `x * H + y`, so
the column-major walk already emits ascending indices (variant 0) and
variant 1 is that list reversed, while the row-major walks put rows in
order by construction with x ascending inside a row supplying the
ascending-index tie-break. Two sorts drop out with them.

Behaviour-identical, and checked rather than argued: against the pre-sweep
binary on seven fixtures with the packing guide confirmed active,
nodesExpanded/turns/steps match exactly on six, including boards expanding
23k and 86k nodes. The seventh (test30) differed only under a wall-clock
budget -- node-bounded at 5k and 20k it matches too, which is the machine-
speed effect dragsolver_search_test.cpp already documents.

Also: explicit captures on computeCutSchedule's validAnchor (S5019/S3608);
the if init-statement for asBase in all four MemoryProbe copies (S6004);
and Held merged into the existing verifyCore import (S3863).

CodeRabbit, beyond the above: dropped `maxNodes == 0 ? 0 : maxNodes`,
which is identity; braced the wrapped `if (beam)` body, whose unbraced
form sits directly above an identical-looking unconditional assignment;
and gave the sequential phase its own seqBudget copy so the race's budget
can stay const.

Button took the intent but not the proposed patch. Copying in getTurns()
would allocate once per button per combination inside turnSolver's search
-- the one search on this site on the main thread. The copy belongs in the
constructor, which is what actually severs the alias to validateConfig's
parsed upload; the getter hands out `readonly number[]` instead, which
stops mutation at compile time for free.

Verified: typecheck, bun test 2401 pass / 0 fail (all five slow suites),
native Release with the clang-tidy gate confirmed enforced x4,
ctest 6233/6233, build:wasm.
