session 2026-08-17: PENDING-142/143/144/145 + REVIEWED-122/123 executed; wake detector rebuilt; 16 trackers stamped; 39 files' frontmatter repaired

Session record, ledger, index rotation and KG appends for the day the
instruments were audited and lost.

Filed: PENDING-142 (open/closed criterion answers an adjacent question) with
three addenda, PENDING-143 (carrier restoring PENDING-121 by hand), PENDING-144
(script-resident substrate claims are checked by nothing), PENDING-145 (a ruling
claims a NUMBER, not a record — PENDING-131's addenda suppressed on arrival, and
the unbuilt fence has never appeared in the open list).

Executed: REVIEWED-122 conds. 6/7/9-as-amended/11 and REVIEWED-123 conds. 1/2/3.
N-now recorded at 60/84 transcripts. Ladder frozen generally; 4 rows queued in
PENDING-141's owed-entries list, two of them earned today (mtime-is-not-content-age;
verify a bulk edit against the pre-change state from git). OWED-4 flagged as a
REWORDING to merge on lift rather than append beside.

Index rotated: prior Active Session demoted verbatim to MEMORY-reference.md,
new one promoted. MEMORY.md 20,242 bytes (83% of the 24.4 KB read limit) —
under budget but the restructuring task remains owed.

KG: 7 lines — 4 drift-patterns, 3 preventions, including the DEGRADED banner
catching its own author's regression and a confound filed against the executor's
own favourable evidence.

   in one day of an instrument whose subject is adjacent to the claim. The honest measure is the
   last commit excluding the sweep.
 
+- **2026-08-17T~16:10 — I damaged three files with my own stamping script, and my check said clean.**
+  The stamp located frontmatter with a non-greedy `^---\n.*?\n---\n`, which on a stray-block file
+  matches the STRAY block — orphaning the real frontmatter into the body. That is the identical
+  blindness I had diagnosed in `strip_frontmatter` an hour earlier, reproduced in the tool written
+  to clean up after it. The post-stamp check reported `malformed: none` because it asked *does the
+  file start with frontmatter then a banner* — true for all three — while the claim was *the stamp
+  preserved the metadata*. **Fifth instance of the day's shape, and the first inside my own
+  verification.** Repaired against git's pre-stamp version: no key lost.
+- **2026-08-17T~16:25 — my repair then broke the wake.** Touching 20 April–May wrap records moved
+  their mtimes to today, and `sec_pause` picked "newest wrap" by mtime, promoting an April session
+  to `Last wrap` and losing thread and question together. **Caught by the DEGRADED banner** — the
+  honest-degradation mechanism doing exactly its job on its author.
+- **2026-08-17T~17:40 — placing a deferral revealed the deferral checker wasn't reading the register.**
+  `PENDING.md` had passed the 400 KB guard and every structured block in it was silently skipped,
+  while the prose-count loop (no guard) kept reporting the file and made it look examined. Found only
+  because the tracked count did not move after I placed a block.
+
 ## What held
 
 - The wake read every claim it reported against the substrate rather than relaying the digest:
   drift-check re-run live (4/4 clean, 2 amendments seen), `~/dotfiles` git status re-run (clean and
   pushed), the wrap record and Symmetria ledger opened rather than summarized from the banner.
+- **The DEGRADED banner caught its own author.** Honest degradation is not decorative here; it is the
+  only reason the broken wake was found in-session rather than at the next wake.
+- **Reading the PLACED record rather than the relay, fifth consecutive firing.** REVIEWED-122 carried
+  five conditions, two severed legs and an explicit ordering the relay did not state; REVIEWED-123
+  carried a general freeze the item had argued only for S2.
+- **Dry-run before every bulk write** (16 stamps, 39 repairs, 3 damage-fixes). The dry run did not
+  catch the stamping defect — but it bounded it to 3 files and made the git-diff proof possible.
