docs(6209): task document, query scrubbing, note pipeline, lesson door, live body, ledger clear, rule usage

Seven more test files: docstrings and comments state the property and its
reason, the SQL-twin note states why `\m` and not `\b` without the install
it broke, and fixture provenance says "real near-miss queries" rather than
naming the spike that collected them.

 The properties that must hold, each with its own way of rotting:
 
-  - A no-forge instance's pull response is BYTE-IDENTICAL to today's (rule
-    #115 — the baseline, not a degraded mode).
+  - A no-forge instance's pull response is BYTE-IDENTICAL to a plain read

   - The probe never rewrites the body: "current" refreshes provenance,
     "diverged" reports, and neither clobbers the record mid-read.
   - A 404 stamps the mechanically-true 'missing' verdict — once, not on
