SCRIP-CORPUS-036: freeze Darwin rendering-surface inventory

[andy-zen-dev]

Closes #159 after independent review/merge.

This draft implements the source-free prerequisite before the Darwin/Rachinsky Page renderer: it audits only the 388 already-pinned literary Page revisions, verifies exact revision identity before transient content inspection, and persists only construct shapes/counts plus digests. No source wikitext/prose, OCR, scan bytes, template arguments or lexical snippets are serialized.

The dedicated workflow prints/uploads the source-free audit so this branch can freeze the verified manifest in a follow-up commit. Rendering/body/admission/FantLab/M2 gates remain closed throughout.

Current head is production-authored and must remain Draft until the audit is captured, committed, exact-head CI settles, and a later run performs independent review.

Production handoff for independent review — exact current head ee97e29af7225131002b6e0922c731536d903d13 against base f5687b95d20e2714cebfcef8370883377c25f0bb.

SCRIP-CORPUS-036 is intentionally left Draft and is not self-approved. All 15/15 exact-head pull-request workflows are now completed success. The final-head dedicated Darwin Rachinsky rendering surface run 35488061151, job 106017954957, passed source-free audit tests, replayed all 388 exact pinned literary Page revisions, rebuilt the durable compact freeze byte-for-byte equal to the committed manifest, and passed gate-boundary assertions. Artifact 10598173002 is 45,088 bytes with sha256:e11f34e0c84fcdc922efa99e019eeaa6a7e499212d2b0d0f6a8c46fb54f6f750. Scriptorium Pages also passed the full standard-library suite, canonical static build and deterministic rebuild; the pinned pylem provider workflow completed successfully as well.

Durable evidence remains source-free: 38 template name/arity shapes, 18 tag name/kind shapes, digest over 388 per-Page source-free receipts 7c170f513bf21f2c9e0d7736bc9fc20b4c9a40fdfe942a7b1dd1b0ac048ba09b, compact freeze digest e5ae625fef6afb2e890de990e1ef3b9e108a409a2e0ea2136947c2c3e1cea44d. No Page wikitext/rendered prose/template arguments/OCR/scan bytes are committed.

Required independent review boundary: rendering_profile_frozen=false, literary_body_count_and_digests_frozen=false, minimum_300k_proved=false, admitted_for_calibration=false, fantlab_source_edition_match=unknown, diagnostic_ready=false, m2_parity_admissible=false. Confirm no source-payload leak and review exact head before Ready/merge.

Independent exact-head review completed on ee97e29af7225131002b6e0922c731536d903d13 against unchanged base f5687b95d20e2714cebfcef8370883377c25f0bb. I found no blocking defect.

Review evidence:

• 14 commits ahead / 0 behind, mergeable, no inline review threads.
• All 15 pull-request-triggered workflows are settled success on this exact head.
• Dedicated Darwin Rachinsky rendering surface run 35488061151, job 106017954957, checked out this exact SHA, passed source-free audit tests, replayed 388/388 pinned literary Page revisions, rebuilt the compact freeze byte-for-byte, kept all downstream gates closed, and uploaded artifact 10598173002.
• I independently downloaded that exact artifact and verified its ZIP SHA-256 matches GitHub metadata (e11f34e0c84fcdc922efa99e019eeaa6a7e499212d2b0d0f6a8c46fb54f6f750). Recomputed canonical digests match the committed evidence: audit cd6b748090298a5a1a4fe0b1bc63feb7e1ba9c49332bb6217e744b3fd7197b49, 388 Page-receipt digest 7c170f513bf21f2c9e0d7736bc9fc20b4c9a40fdfe942a7b1dd1b0ac048ba09b, and compact freeze e5ae625fef6afb2e890de990e1ef3b9e108a409a2e0ea2136947c2c3e1cea44d.
• Full/compact template shapes, tag shapes and aggregate counts agree; receipt sequences are exactly 388 unique literary sequences, with no payload fields or committed Page prose/template arguments.
• rendering_profile_frozen, literary-body identity/count, >=300k admission, FantLab source match, diagnostic readiness and M2 parity remain closed as required.

Because this connected identity authored the PR, this is deliberately a review comment rather than a self-approval. Evidence supports marking Ready and squash-merging with expected-head protection.
