check-in 2026-10-11 (zephyrus): Q20 sample audit done (26/26 literal), lane correction - Cassian took Q21 (e3b2f4b), I took Q20 per 18:13Z reconciliation; push owed

Supersession note (2026-10-12): Merlin's full-population Q20 audit (9a1de9a, 269/269 literal, pipe-verified reply 20) closed Q20 while my two commits were egress-blocked; my sample verdict agreed. Audit file landed as recoveries/excerpt-placement-audit-zephyrus-sample.md (renamed on rebase so Merlin's deliverable at recoveries/excerpt-placement-audit.md is untouched).

+landed 2026-10-11 (Cassian's lane, not mine — noted, not folded). Remote stood at 9c0fb1b
+(origin/main) when this run started; local HEAD ccc6eb7 (Q20 audit) is 1 ahead — push owed,
+no egress from this context. The 09:06 ET standup run timed out incomplete (Q20 subagent
+pending); this file completes its Did from the finished deliverable.*
+
+## Did
+
+- **Q20 excerpt-placement audit done.** 9 magazine entries every-10th (002–082), 26 excerpts:
+  **26 literal / 0 paraphrase / 0 everything else**. All 9 cited article URLs answered HTTP 200;
+  every excerpt is an exact substring of the fetched target page after the printed
+  detag/normalisation rule. Placement fractions 0.0000–0.9381 across ledes, middles and
+  closes. One placement caveat: magazine-082 is an embedded interactive app, so its two
+  excerpts match the page title (offset 0) and the magazine's author-note — graded literal
+  by the stated rule. Readings from this host 2026-10-11T13:09–13:10Z (dated readings, not
+  re-verified this tick). Deliverable `recoveries/excerpt-placement-audit.md` (13,368 B),
+  committed ccc6eb7 local-only — push to origin owed. Awaits Timmy's verification.
+- **Lane correction — yesterday's "I take Q21" line is stale.** Cassian executed Q21 overnight
+  (e3b2f4b, on origin/main): 121/121 entries, 319 excerpts, 116 anchors all 200 —
+  311 bound (300 verbatim / 7 marked-elision / 4 URL-tokenised), 4 mis-bound, 4 unanchored.
+  The four mis-bound are one real defect: the Skinner Stacking corroboration quote on
+  block-25/88/89/90 attaches to the bare site root (detags to 5,009 chars, Skinner x0)
+  while the passage is verbatim at /a-conversation-with-burnchainers/; the four unanchored
+  are the The-block testimony quotes, correct as testimony-only. The control plane's
+  18:13Z label reconciliation in WORK-QUEUE.md names Q20 as my next unit verbatim
+  ("do not start Q21, which is closed at e3b2f4ba"), superseding reply-51's lane ruling.
+  So: **Cassian took Q21 (done, clean), I took Q20.**
+
+## Corrections to my own record (own errors first)
+
+- The 10-10 check-in's Ask ("I take Q21 next tick unless you point it elsewhere") is
+  superseded by the reconciliation above — no separate claim needed, the queue record
+  already says it. Nothing else of mine is open.
+
+## Next
+
+- Q20 awaits Timmy's verification reply to close. If he returns corrections, I fold them
+  the same tick.
+- Push owed (network-capable context): ccc6eb7 (Q20 audit) + this check-in. Nothing else
+  is staged.
+
+## Ask
+
+- No new asks. Standing gates unchanged and all Alexander's: Q9 audio handover, Q13/Q19
+  publication, new-wizard credential flow (Inbox item 31).
