 # P08-03 condition matrix — implementation submission, not acceptance
 
+## Repair13 current status (supersedes earlier submission status below)
+
+Checker/test-only repair. Product, Runtime, Godot, collector, same31aa and rawR09
+bytes are unchanged. Root supplied the read-only **post-collection** sips
+measurement of 138 images; this is not capture-time metadata. All measured
+screenshots are 1280×752 JPEG despite their .png names. Window content size
+1280×720 is never used as screenshot dimensions.
+
+The checker reads every image, checks SOI/EOI and bounded SOF0/SOF2 frame/scan
+structure, and compares its dimensions and recomputed SHA against the Root
+measurement and index. This is structural validation, not JPEG pixel decoding.
+The measurement's original_index_sha256 binds the recomputed index. Exact
+69-request/138-image membership and before/after dimensions are checked;
+formal save thumbnails retain their separate existing member checks.
+
+Collection pins bind the original index, runner receipts and both OS receipts;
+every indexed original/canonical artifact must be byte-identical. Owner proof
+is verified at ORIGINAL_ROOT/os-runs/{writer,reader}/teardown/control.json,
+retaining original absolute varbytes pins without rewriting them.
+
+Reuse is restricted to same31aa (`31aa7706d28a92e313c432d5a62e35d19503dcc3`):
+all collected source/input hashes still match, except the two explicitly
+changed Python validator/test sources and the new synthetic Python image
+fixture. The old validator/test pins are checked against same31aa git objects;
+product, GDScript fixtures, engine, recorder, controller and marker pins remain
+exact. This exception does not confer gameplay or changed-product acceptance.
+
+Current local Python results and final executed hashes are in
+`repair13-local-validation.json`, `repair13-local-source-manifest.json` and
+`implementation.json`. All 88 previous tests remain; 12 additional controls
+cover baseline/progressive parsing, malformed/truncated/non-JPEG bytes,
+SOF/measurement disagreement, before/after drift, missing/extra/duplicate
+entries, extra indexed screenshots, source SHA, stale index, collection pin
+and original/canonical divergence. Synthetic fixtures have no dependency on
+operational Root handoff documents.
+
+All five conditions remain unaccepted. R09 local integrity validation is not
+the independent R09 re-check. Leave open: stair preview/domain-status
+disagreement for independent acceptance, Windows same-distribution/device,
+Root final175 after frozen submission, R09 re-check, independent Opus review,
+and integration/current verification/ledger. No OS steps were replayed.

+# Repair12 recorded direction: context gap
+
+Status: blocked; no checker implementation submitted. Inspected checkout HEAD
+`31aa7706d28a92e313c432d5a62e35d19503dcc3`. Contract base remains
+`12430ba89970bda349781e51157e72e48a4ac06f`.
+
+The instruction requires JPEG SOF dimensions to match recorded before/after
+dimensions. The available canonical R09 collection has 69 request.json,
+69 ack.json and 69 input-receipt.json files. None contains recorded screenshot
+before/after dimensions. The two indexed root-cua-ack-controller Python sources
+also write no such dimensions. The concrete example
+`os-pair/writer-request-0058/screen-before.png` has JPEG SOF dimensions
+1280 x 752; its request.json records window_size 1280 x 720. Window size
+therefore cannot substitute for screenshot dimensions. Extracting both sides
+of a comparison from the same JPEG would not independently bind dimension drift.
+
+Required context: identify and provide the existing, attributable R09 record
+of before/after screenshot dimensions and its relationship to these 138 image
+files. Do not invent records or change originalR09. If no such record exists,
+the owner must resolve this requirement explicitly; the worker cannot silently
+replace it with SOF self-consistency or window dimensions.
+
+Original root access returned `Operation not permitted`:
+`/Users/korizatou114/Projects/とりにく工房ゲーム制作部/artifacts/original-completion-2026-10-02/p08-03-native-os-r09`.
+The canonical copy was readable at
+`/Users/korizatou114/Projects/TheTree-managed-worktrees/p08-03-code/.runtime/P08-03/build/p08-normal-placement-evidence`.
+Original/canonical byte equality was consequently not established by this worker.
+No security settings were changed. Pillow is unavailable in the worker's Python.
+
+Read-only Python inspection established:
+
+- All 753 files listed in the canonical index match their indexed size and
+  recomputed SHA256. This is an indexed-byte audit, not a complete file-set gate
+  or acceptance result.
+- Every current source_map member and input member matches the R09 index,
+  including product source, fixtures, controller, recorder, marker contract,
+  spec and inputs. The engine binary matches runner-input.json's engine SHA256.
+- os-proof.json names `os-runs/writer/ended.json` and
+  `os-runs/reader/ended.json`. Recorded owner control paths use
+  ORIGINAL_ROOT/os-runs/{writer,reader}/teardown/control.json.
+  The original absolute varbytes pin must remain enforced.
+
+Only this scoped document was added. Checker, tests, product and evidence bytes
+were not edited. No tests, native engine, OS replay, regression, git writes,
+Runner operations or agents were run. These inspections are not JPEG validity
+checks and are not sufficient for acceptance.
+
+All requested validator repairs and negative tests remain pending. Root's final
+full175, R09 re-check, independent Opus review and integration remain required.
+Preview/domain-status disagreement and Windows same-distribution remain open.
