The overlay is anchored to a captured photograph; glyph +centres/edge endpoints are mapped by the crop homography for readability. +Native-camera autofocus/exposure and installation should also be checked on +physical iPhones; a mobile WebKit test is not a physical-device test. + +## Data contract + +```json +{ + "version": 1, + "type": "sudoku", + "rows": 4, "cols": 4, "boxRows": 2, "boxCols": 2, + "cells": [1, null, 3, 4, 3, 4, 1, 2, 2, 1, 4, 3, 4, 3, 2, 1], + "cages": [], "inequalities": [], "clues": [] +} +``` + +Cells are row-major. Null is blank; `"#"` is blocked. Slitherlink 0 is a real +face clue; the engine's private OFF=1/ON=2 edge encoding is not exposed as clues. +Cages: `{ "cells": [0,1], "target": 3, "op": "+" }`. Every cage must be connected +and every cell must belong to exactly one cage. KenKen supports +, -, *, /; +`=` is accepted for a single cell. Inequalities: `{ "less": 0, "greater": 1 }`. +Kakuro clue on a black cell: `{ "cell": 0, "across": 16, "down": 23 }`. +Across/down runs extend right/down until the next blocked cell or the boundary. +All coordinate indexes are zero-based. The Python adapter performs complete +structural validation before building the original grid classes. + +The bounded 25×25 UI limit is a phone resource policy, not a reduction of the +native solver's supported sizes. Large blank/path puzzles may take substantial +search time. A deadline means unfinished, never unsatisfiable or unique. + +## Testing + +`tests/test_web_api.py` checks native adapter semantics and all model families. +`web/tests/model.test.js` checks row-major data, inference ambiguity, homography, +white-image rejection and generated-grid detection. `scripts/browser_smoke.cjs` +uses the real Python and OCR WASM runtimes, not mocks, in Chromium and WebKit. +It checks all eleven families, phone overflow, clue editing/undo, genuine +cancellation/restart, denied camera fallback, a generated printed Sudoku scan, +photograph overlay and offline reload/solve. Reports and screenshots are CI +artifacts. This is a baseline, not a measured real-world recognition benchmark. diff --git a/web/app.js b/web/app.js new file mode 100644 index 00000000..d836af33 --- /dev/null +++ b/web/app.js @@ -0,0 +1,231 @@ +import {TYPES,makePuzzle,demo,clone,checkShape,conflicts,isCage} from './model.js'; +import {Scanner,canvasOf,imageOf} from './scanner.js'; +import {homography,project,validQuad} from './geometry.js'; + +const $=id=>document.getElementById(id),NS='http://www.w3.org/2000/svg',scanner=new Scanner(); +const state={puzzle:makePuzzle(),uncertain:new Set(),needsReview:false,notes:[],result:null,solution:0,photo:null,rectified:null,corners:null,photoRows:0,photoCols:0,view:'board',selected:[],history:[]}; +let worker=null,jobId=0,busy=false,timer=null,deadline=null,started=0,stream=null,cameraEpoch=0,editing=0,drag=-1,focused=0; +const storage={get:key=>{try{return JSON.parse(localStorage.getItem(key));}catch{return null;}},set:(key,value)=>{try{localStorage.setItem(key,JSON.stringify(value));}catch{/* Private/storage-full mode must not break solving. */}}}; +for(const [value,label] of Object.entries(TYPES)){const option=document.createElement('option');option.value=value;option.textContent=label;$('puzzle-type').append(option);} +const prefs=storage.get('gridpuzzle-settings-v1'); +if(prefs){if(prefs.type==='auto'||Object.hasOwn(TYPES,prefs.type))$('puzzle-type').value=prefs.type;for(const id of ['auto-capture','auto-solve'])if(typeof prefs[id]==='boolean')$(id).checked=prefs[id];if(['0','30','90','300'].includes(prefs.limit))$('time-limit').value=prefs.limit;} +function savePrefs(){storage.set('gridpuzzle-settings-v1',{type:$('puzzle-type').value,'auto-capture':$('auto-capture').checked,'auto-solve':$('auto-solve').checked,limit:$('time-limit').value});} +for(const id of ['puzzle-type','auto-capture','auto-solve','time-limit'])$(id).addEventListener('change',savePrefs); +function status(text,detail='',kind='info',progress=null){ + $('status').className=`status ${kind}`;$('status-text').textContent=text;$('status-detail').textContent=detail; + $('progress').hidden=!busy;if(progress===null)$('progress').removeAttribute('value');else $('progress').value=progress; +} +function fail(error){if(error?.name!=='AbortError')status(error?.message||String(error),'Nothing was uploaded or sent to a remote solver.','error');} +function remember(){state.history.push({puzzle:clone(state.puzzle),uncertain:[...state.uncertain],needsReview:state.needsReview,notes:[...state.notes]});if(state.history.length>30)state.history.shift();} +function persist(){storage.set('gridpuzzle-puzzle-v1',state.puzzle);} +function stopTask(message=null){ + jobId++;scanner.cancel();if(busy&&worker){worker.terminate();worker=null;}busy=false;clearInterval(timer);clearTimeout(deadline);timer=deadline=null;$('stop').hidden=true;$('solve').disabled=false;$('progress').hidden=true;$('status').setAttribute('aria-busy','false'); + if(message)status(message,'Search unfinished.

Advanced puzzle data

A data-only format for all eleven families. Cells are zero-based row-major indexes; null is blank, # is blocked, and Slitherlink 0 is a clue.

Isolate task/edit/photo/offline ownership, share grayscale off-thread, own OCR children during initialization and preserve concurrent guided-review/grid-artifact improvements. Include exact stack-safe cage enumeration and uncapped parallel-error observation from master without weakening deductions or changing positive-cap semantics. Final pre-merge Python 3.14.7 CI: 660 passed Linux, 658 Windows, 32 slow deselected each. Actual installed-wheel solves, forward compatibility (3.14t/3.15), JavaScript regressions and both actual Chromium/mobile-WebKit suites passed. Retained reports cover 27 end-to-end checks per engine, all eleven puzzle families, cancellation during real OCR language loading, poisoned-cache recovery, and origin-offline solving/scanning. Concurrent scanner variation/review suite also passed. Temporary write-enabled validation tooling removed. Target is browser-scanner only; original app PR #18 remains separate from master. --- .github/workflows/browser-tests.yml | 20 + benchmarks/review3_browser.json | 263 +++++ benchmarks/review3_browser.md | 25 + benchmarks/review3_native.json | 191 ++++ benchmarks/review3_native.md | 9 + benchmarks/review3_recognition.json | 123 +++ gridsolver/rules/sumrules.py | 45 +- gridsolver/solver/solve_parallel.py | 23 + scripts/browser_regressions.cjs | 420 ++++++-- scripts/browser_smoke.cjs | 722 ++++++++++++-- scripts/build_web.py | 70 +- tests/review_parallel_probe.py | 4 +- tests/test_review3_native.py | 118 +++ tests/test_review_fixes.py | 2 + tests/test_solver_api.py | 5 +- tests/test_web_review3.py | 47 + web/README.md | 12 + web/app.js | 1284 ++++++++++++++++++++----- web/edit-history.js | 22 + web/geometry-worker.js | 33 +- web/geometry.js | 349 +++++-- web/index.html | 432 +++++++-- web/model.js | 428 +++++++-- web/ocr-host-worker.js | 62 ++ web/ocr-map.js | 125 ++- web/offline.js | 78 ++ web/photo-flow.js | 442 +++++++++ web/scan-analysis.js | 171 ++++ web/scanner.js | 458 ++++++--- web/session.js | 52 +- web/solver-worker.js | 52 +- web/style.css | 721 +++++++++++++- web/sw.js | 200 +++- web/task-controller.js | 62 ++ web/tests/cache-recovery.test.js | 88 ++ web/tests/classification.test.js | 25 +- web/tests/controllers.test.js | 66 ++ web/tests/fixtures/payloads.json | 308 ++++++ web/tests/input-safety.test.js | 26 + web/tests/model.test.js | 153 ++- web/tests/ocr-map.test.js | 99 +- web/tests/scanner-regressions.test.js | 125 ++- web/tests/session.test.js | 73 +- web/tests/worker-lifecycle.test.js | 142 +++ 44 files changed, 7139 insertions(+), 1036 deletions(-) create mode 100644 benchmarks/review3_browser.json create mode 100644 benchmarks/review3_browser.md create mode 100644 benchmarks/review3_native.json create mode 100644 benchmarks/review3_native.md create mode 100644 benchmarks/review3_recognition.json create mode 100644 tests/test_review3_native.py create mode 100644 tests/test_web_review3.py create mode 100644 web/edit-history.js create mode 100644 web/ocr-host-worker.js create mode 100644 web/offline.js create mode 100644 web/photo-flow.js create mode 100644 web/scan-analysis.js create mode 100644 web/task-controller.js create mode 100644 web/tests/cache-recovery.test.js create mode 100644 web/tests/controllers.test.js create mode 100644 web/tests/fixtures/payloads.json create mode 100644 web/tests/input-safety.test.js create mode 100644 web/tests/worker-lifecycle.test.js diff --git a/.github/workflows/browser-tests.yml b/.github/workflows/browser-tests.yml index f4b75f65..2f11a31b 100644 --- a/.github/workflows/browser-tests.yml +++ b/.github/workflows/browser-tests.yml @@ -25,3 +25,23 @@ jobs: - run: node --test web/tests/*.test.js - name: Check every browser module parses run: find web -name '*.js' -not -path '*/vendor/*' -exec node --check {} \;

reload/solve and offline photo recognition. Reports and screenshots are CI artifacts. This is a baseline, not a measured real-world recognition benchmark. + +## Input, build and lifecycle hardening + +The editor validates dimensions and Sudoku boxes before allocation, persistence or rendering. Invalid saved sessions fall back to a clean board. Shared JSON fixtures distinguish incomplete-but-editable states from solve-ready inputs; the Python adapter remains the final structural boundary. + +Builds are staged before publication. Inside the repository, only `_site` is accepted as output; a custom external path must be new or contain the builder's ownership marker. Existing unmarked directories (including outputs from older builds) are never deleted: move them aside before rebuilding. Source directories, the Git directory, repository ancestors and symbolic output links are rejected. A failed build preserves the previous good output. + +Offline requests, readiness checks and preparation use the same digest verifier. Corrupt entries are evicted and retried from the network. Readiness is checked against actual verified entries, not just cache-key presence, and online use can continue even if cache quota is exhausted. + +Task/deadline ownership, edit snapshots, camera/photo flow and offline controls have separate modules. Grayscale is computed once for scan preparation; thresholding and region extraction run in the geometry worker. Each OCR scan has a dedicated host owning its raw Tesseract worker during engine and language initialization. Stop rejects the pending task immediately, requests child termination, and bounds host cleanup to 100 ms; each worker has a three-minute fallback deadline and the complete recognition task has a two-minute deadline. Real-browser tests stall language loading, stop the scan, check worker cleanup and then perform a fresh successful scan. + +These lifecycle changes do not substitute or reorder any solver technique. diff --git a/web/app.js b/web/app.js index 8c51ac63..2e60a111 100644 --- a/web/app.js +++ b/web/app.js @@ -1,265 +1,1063 @@ -import {TYPES,makePuzzle,demo,clone,checkShape,conflicts,isCage,nextReviewCell} from './model.js';

Character bounding - boxes preserve clue boundaries even when OCR merges a row into one word. - Type recognition is explicitly heuristic; ambiguous rules require confirmation. -- Eleven native solver families: Sudoku, Killer Sudoku, Futoshiki, KenKen, - Latin square, diagonal Latin square, pandiagonal Latin square, Hidato, - Numbrix, Kakuro and Slitherlink. -- Digit/block editor with enlarged source crop, cage partition editor, directed - inequality editor, Kakuro across/down clues, undo and validated JSON import. -- Explicit type override preserves the transcription, but refuses to silently - discard incompatible structural constraints.

Zero/multiple/unique/error/invalid - states are distinct. Worker termination implements real cancellation and - search deadlines; stale messages cannot replace a newer puzzle. -- Clean board and captured-photo solution overlay, both number and loop-edge - puzzles; PNG overlay export and puzzle JSON export.

The intended follow-up (staged as a base64 tar under .followup with a push-triggered workflow that would also have recorded an `-s ours` merge of master) never applied, so the branch carried patch files that duplicated app.js logic. This applies the reviewed parts directly and removes the payload and its workflow. Service worker and offline - cache-recovery tests target offlineReadyFast/offlineReadyVerified and digest-keyed entries; the routing test moves here as well. - The fetch handler falls back to the network when the build's asset list is missing or stale instead of rejecting every in-scope request; explicit offline preparation restores an evicted list while online. - Offline preparation asks for persistent storage after verification. Application - model.js gains moveIndex, hasCageRemoval, hasInequalityRemoval and checkSolveReady (cage coverage and targets, Kakuro run structure), and app.js uses them for keyboard bounds, no-op removal guards and the Solve entry points; accessibility.js and polish.css are folded into the core. - Loading a board no longer rewrites the scan type preference; settings move to gridpuzzle-settings-v2 and a migrated type resets to automatic. - Photo import decodes at working size through createImageBitmap when the header dimensions are known, with a bounded full-decode fallback. - index.html declares a same-origin Content Security Policy and no-referrer; svg() applies style declarations through CSSOM so style-src stays strict. Build and CI - build_web.py verifies each npm tarball against a pinned SHA-512 integrity value, ships only the LSTM Tesseract cores the OCR host uses, reads and writes text as UTF-8, and resolves npm.cmd on Windows. - browser-pages.yml uploads both artifacts with upload-artifact@v7; build and acceptance outputs are ignored by git. - The smoke script fails on CSP violations, probes the poisoned-cache repair through digest keys, stubs a missing mediaDevices, and checks offline root navigation with a query string. Verification: 67 node unit tests pass; pytest 690 passed, 1 skipped on the merged tree (web adapter and build tests re-run after the build script edits); the build verifies all four tarball pins and emits 41 assets; the Chromium 153 and WebKit 26.6 acceptance smoke passes all 28 checks per browser with no CSP violations, including offline query-string navigation and content-addressed poisoned-cache repair; JPEG import at fixture size and at 25 megapixels detects the grid in both browsers. The recognition regression baseline reads 29/30 on this Windows host with the misread cell flagged, identically with and without the new decode path, so that strict assertion depends on the CI runner's fonts rather than on this change.

Subject: [PATCH 72/86] Add Str8ts and real-newspaper OCR regressions Add exact native Str8ts solving, browser/data-boundary support and black-cell editing. Harden digit extraction for shaded and dirty newsprint with solid-block detection, connected-component cleanup and per-cell Otsu binarization.

Retain verified versioned solver archives for dedicated workers already alive when another tab activates an update. Preserve their original URLs across later updates and prune archives once those worker clients close.

Single-character recognition of an isolated crop fails in different ways (empty reads on thin strokes), so neither reader is trustworthy alone. The OCR host now re-reads every single-glyph digit after the atlas, in the same session, as a single character: once from the binary crop that feeds the atlas and once from the grayscale crop at the same bounds. Each read costs a few milliseconds on the warm worker. The scanner votes per digit: unanimity of at least two readers is confident even when their individual scores are low, since they fail independently; any disagreement, or a lone reading, keeps the review flag. Wide crops are multi-digit clues that the single-character mode cannot read and keep the atlas result; the grayscale variant is skipped above 150 digits to bound the cost. Measured on the generated 9x9 fixture in eight fonts, both browsers: atlas only 364/480 clean, 110 correct-but-flagged, 1 unflagged misread voting 453/480 clean, 26 correct-but-flagged, 0 unflagged misreads On this Windows host the variation regressions now read every variant completely in both browsers, including the serif case that read 27/30 before; the real newspaper Sudoku drops from six review flags to one.

The same photograph reads fully through the deployed build in Chromium and WebKit, even reduced to a 500-pixel page photo, so the device was either running a stale app or hitting an engine failure that desktop cannot reproduce. Both cases were silent: the app showed an ordinary review prompt, and the only update control sat inside the collapsed offline section, where a phone user never sees it. Two changes make the next such report diagnosable and the stale case unlikely. When a scan marks three or more printed cells and reads no digit at all, the review note now says so and includes how many regions returned any text and the app build, and it tells the user to install an offered update or retake the photo. A banner under the masthead mirrors the update control whenever a new version is waiting or another tab activated one; it uses the same handler, so nothing reloads until the user chooses to.
