volt: Q71 (part 2/2) -- closure record, evidence doc, and the pin re-made reproducible; --record fixed to write the cited URL, not the resolution fetch

Closure of Q71 (ledger's commits-table.md). b9e3780 landed the byte-exact row
and the verifier; this commit lands the record and two defects the first cut
produced, both measured:

1. The pin was not reproducible. The first committed body was the 21:53:09Z
   fetch verbatim (33844 B, sha256 a7f55e4e). --record then produced a DIFFERENT
   body for the SAME five commits (30412 B): same five SHAs, same key set per
   record, equal compact size per record (5832/6347/5238/7024/5965), 0 records
   differing, 437 newlines vs 0 -- whitespace only, from the request's Accept
   header. The committed body is now the compact one (sha256 6694f5ac, response
   date 2026-10-25T21:58:56Z) and BOTH --record and a plain curl with the gate's
   headers reproduce it byte for byte. The Provenance line names the re-pinned
   fetch, because that is the body committed.

2. --record wrote the body it graded from, i.e. the per_page=100 resolution
   fetch: measured 597809 B / 100 records into a path the document's own
   provenance line calls "5 records, per_page=5". Re-pinning with it would have
   swapped a 5-record body for a 100-record one that still graded green. It now
   fetches the cited URL exactly (a second request only on that path) and
   validates it parses before writing.

Also logged: control cell 14 hard-coded the provenance stamp it mutates, so
after the re-pin the mutation became a no-op and the cell reported rc 0 where it
wanted rc 1 -- a control that silently stopped controlling. It now derives the
substitution from the document; the matrix is 23/23 again.

Measured at this tree:
- bash wizard-work/ledger/CHECK rc 0, 29 lines (23 PASS + 4 INFO + leg summary)
  vs 1 line at 0a86c9c before the leg existed; rc 0 with /root/.hermes masked
  (unshare -m + tmpfs, 0 entries).
- Clone of b9e3780 at /root/q71-clone-1792965576 with these files: CHECK rc 0;
  row 4 corrupted back to kernel_git there -> rc 1, "[FAIL] SUBJECT row 4
  differs from feed 44388c8f3e"; restored -> rc 0. The leg proves itself inside
  CHECK, not only under its own harness.
- git archive export of b9e3780 (no .git): verifier rc 0 pinned and rc 0 live.
- 23/23 control cells (scratch/q71/controls.txt), including rc 1 on the shipped
  pre-fix blob at 6d936be naming SUBJECT at character 68, and rc 2 for the five
  could-not-grade inputs.
- python3 tools/verify.py --repo . -> 8 legs, 8 pass, 0 fault, 0 ungradable.

Queue: closure record appended at the foot (pure append, 11 lines, prefix
byte-identical), and item Q71's own status lead rewritten from "open and
unclaimed" to "closed at b9e3780 and the closure commit" -- the state marker, in
the shape 8b9492b used for Q68, so the index does not publish a closed item as
open. queue_claim_check: Q71 out of the open set; docs/queue-index.md
re-rendered in this commit.
