Presentation QA v3 B1 slice 05: Alt-text authored on 29 mascot records

Maintenance ID: 0.1.00263.presentation-qa-v3-b1-05 Date: 2026-10-09 Scope: content/mascots/ — issue #998 B1 slice 5 (29 records: 251–279 contiguous)

What changed

One Alt-text: line was authored per record under the pass-3 B-track register constraint (deadpan, concrete visual inventory, evidence-bounded; exemplar mascots/M-0019, merged pilot precedent 0.1.00261.presentation-qa-v3-b1-pilot). All twenty-nine authored lines are quoted verbatim in the PR body with per-line source evidence for maintainer register review.

  • None of the 29 records carried a ## Image section or any Alt-text: line; a ## Image section was created on every record.
  • On 23 stub-layout records (251, 253–259, 261, 263–274, 276–278), the unlabeled lead prose functions as biography; ## Image was placed before the first headed section (## Aphorisms on most, ## Distinction on 252, ## Archival Purpose on 261, ## Boundary Note on 279).
  • On the three full failure-signature records: 260 carries a literal ## Biography and received ## Image directly before it; 262 and 275 have no ## Biography and no unlabeled lead prose, so ## Image was placed before the first narrative section (## Recourse Cushion Classification, ## Classification).

What was deliberately left alone

  • All frontmatter, canonical IDs, titles, tags, and statuses.
  • No other wording, ordering, verse tails, or formatting. No frontmatter image: keys or .assets/ references were introduced; each Alt-text: line is body text only.
  • Irregular layout residue noticed while reading (unheaded Role/Function/Slogan field blocks on 278 and 279; ### Assurance Desk Audit floating inside the lead section on 253; ## Haiku Log wrapping a ## Haikus sub-section collection-wide) was left as-is; residue is not this slice's business.
