+# Checker encoding correction
+
+The first actual data-only checker run refused at `inspect_runtime.py:354`, `assert (fixture / name).read_bytes() == text.encode()`. Exit1; no successful readback JSON was written. The unchanged CLI project fixture was149bytes, whereas the executed checker incorrectly expected153bytes. Participants106bytes and children85bytes matched.
+
+`checker-first-refusal.log` preserves the actual traceback text returned by exec for that run (transcribed from the tool result, not a separately redirected raw stderr file and not a replay). The preserved original checker was actually executed and refused; it is not an unrun predecessor.
+
+This was an evaluator authoring defect: a Windows default-encoding `read_text()` source rewrite turned the intended literal `雨` into mojibake. Actual fixture bytes were UTF-8 `e9 9b a8`; the executed checker literal contained `c3 a9 e2 80 ba c2 a8` (`雨`). Python reads its source as UTF-8, and parsing the preserved raw checker bytes confirms153bytes. The actual CLI fixture and captured original/after inventories remained correct. No product/source/fixture or runtime receipt changed.
+
+Independent packet audit corrected an error in the first version of this note: it had claimed161bytes and a second encoding expansion. That result came from the author's secondary diagnostic probe, which called `ast.parse(p.read_text())` using Windows default encoding on the already corrupt UTF-8 checker file. Repeating that exact data-only probe yields161bytes and prefix `c3 83 c2 a9 c3 a2 e2 82 ac c2 ba c3 82 c2 a8`; it is not what Python executed. Parsing `raw.decode('utf-8')` instead yields the correct153-byte account above. The first packet candidate is preserved locally; its note is superseded by this explicit correction. Original failed checker, refusal transcript, corrected checker, successful readback and application evidence are unchanged.
+
+Preserved failed checker bytes as `inspect_runtime_encoding_original.py`, SHA256 `b544cdb20dc8f5cf1b5d29c5ab78791dd3ac6701a4c1f7f7229f0d73dac7b81e`. The only correction replaced that project-comment literal with Python's explicit `\u96e8` escape using an explicit UTF-8 read/write. Corrected checker SHA256 `db853cc7677421e1abc13e59ca7d181fdcf7bcb45033164e51e09f13ca51c172` then exited0 and produced `ORDINARY-RUNTIME-READBACK.json`, SHA256 `3ee36b331431736062db7ea9fa94876795f61711d44820f5b5093e97cc515db5`.
+
+No comparisons were removed or normalized; complete expected UTF-8 bytes still must match. Only Git and data reads ran, never Cargo or product executables.
