Closes #267.

Product change

Generate a readable standalone HTML report from the existing source-free frozen diagnostic:

python -m scriptorium.frozen_diagnostic_report \
  benchmarks/fantlab/work270306-wikisource-diagnostic.json \
  --title "Anna Karenina — full-work diagnostic" \
  --output anna-diagnostic.html

The report shows all 28 historical rows (23 numeric actuals, five missing), units, expected/actual/raw delta, grouped families and replay identities. Missing is not zero. Omitted families, observations and M2 status are explicitly historical, not a new replay or current provider-status claim.

Safety / correctness

• Reject schema/field drift, duplicate JSON keys, malformed status types, non-finite/out-of-range numbers, inconsistent deltas, pass/fail promotion and source-text/source-match gate changes.
• Preserve integer precision above 2^53 and small nonzero deltas; floating arithmetic consistency is not a parity tolerance.
• Offline, escaped HTML with captioned tables, keyboard-scrollable regions, skip link, visible focus and responsive styling. Create-only output preserves existing reports.
• No changes to historical benchmark bytes, analyzer formulas, corpus admission, morphology, science gates, workflow permissions or Pages activation.
• Add a README example and documentation; reconcile the Oct 2 owner direction into the existing compact queue rather than creating another control plane.

Executed verification

• Local focused module suite: 23/23 PASS, including exact canonical diagnostic blob 0d5e420abb45e2b9e178df75a479ab7cdd5a4150.
• Compile checks and real canonical JSON → HTML CLI: PASS.
• Uploaded module/test blobs exactly match the tested local bytes: eade9e09e6e7ba0efe81144c91c9710849dc3654 / cf688a44dd26f2afad71b0cbf2e6e8e974a14401.
• Full canonical suite was NOT_RUN locally: the execution container has only the verified subset; unauthenticated repository clone failed DNS. The existing Pages PR workflow runs the full suite and deterministic site rebuild at the exact PR head.
• VISUAL_NOT_VERIFIED: Chromium launched, but navigation to the generated local HTML returned net::ERR_BLOCKED_BY_ADMINISTRATOR. No browser restriction was bypassed. Structural accessibility/escaping tests are not screenshot evidence.

Acceptance boundary

This is a code-authoring run; do not merge this semantic change in the same run. A later fresh acceptance must inspect the exact head, code/context, discussions and applicable CI. No GitHub self-approval is requested.

This PR supplies the standalone report, not a live Pages route. Next SCRIP-SITE-008 must reuse/revalidate these primitives and test actual integration: the old local patcher had an indentation defect despite its string-only self-test passing. #266 is already merged and is not a dependency/blocker.

Exact-head verification update for 5ad1ec9e80336546cb214fcb907a1d5bc59ec4b9:

• All 22 returned PR-triggered workflow runs completed success.
• Pages run 37450729048, job 112226385311, checked out that exact SHA. Read the actual job log: 651 tests passed, including all 23 new report tests, on CPython 3.13.15.
• Canonical static build, byte-identical rebuild, symlink check and Pages-artifact upload all passed. Deploy was correctly skipped on this PR; this does not publish the new standalone report as a Pages route.
• Changed-file readback confirms six intended files only. README is an 18-line additive example; retained corpus/science invariants are untouched by queue reconciliation. Tested module/test blob hashes match the committed files.
• Browser visual verification remains blocked by net::ERR_BLOCKED_BY_ADMINISTRATOR on local-file navigation; no screenshot or live verification is claimed.

Ready for a later fresh acceptance on the then-current head/base/checks. Not merged or self-approved in this authoring run.

Owner-requested delivery pass (2026-10-07), completed repair:

• Found the four missing word/sentence unit denominators at 5ad1ec9e80336546cb214fcb907a1d5bc59ec4b9; fixed in this same PR branch at 50fbb9b9c0da59a5eb78c6826381b8acd3dd8aae using a non-forced expected-head update.
• Explicit mappings for the four canonical mean-length IDs; three added regression tests cover those units, unchanged control units and the real 28-row historical artifact. Historical diagnostic blob 0d5e420abb45e2b9e178df75a479ab7cdd5a4150 is unchanged. No analyzer formulas, source text or science gates changed.
• Exact-head hosted verification: all 22 returned PR-triggered workflow runs completed successfully. Pages run 37616533562, job 112776103132, checked out the fixed SHA and passed 654 tests, canonical site build, byte-identical rebuild and artifact upload. Deploy was skipped on the PR, not passed/live.
• This run materially fixed the change, so it is not a merge-acceptance run and no self-approval/merge was performed. A later fresh acceptance can review the then-current head, base, discussions and applicable checks.
• SCRIP-SITE-008: canonical full-work report and reader-first homepage #272 now contains the scoped site integration stacked on this exact corrected head. Do not merge SCRIP-SITE-008: canonical full-work report and reader-first homepage #272 into this feature branch; merge this PR after qualifying acceptance, then retarget/reconcile SCRIP-SITE-008: canonical full-work report and reader-first homepage #272 to master. SCRIP-METRIC-003: private local analysis with JSON and offline HTML #270 is an independent local-analysis feature and need not wait on this stack.

Owner-requested review of exact head 50fbb9b.

Reviewed the standalone renderer/validator, corrected mean-length units, README/docs and queue changes. The historical 28-row artifact remains source-unmatched; unknown values, integer deltas, escaping and scientific labels are preserved. Current provider read returns 22/22 successful PR workflow runs; no inline review threads exist. The earlier unit-denominator finding is fixed.

No new blocking defect found in the curated-artifact rendering path. CLI follow-up: main() still uses unbounded read_text and raw exception messages; keep input curated and adopt the common bounded/path-private I/O when integrating the reader commands. Visual acceptance is still NOT_RUN, not implied by structural tests or CI. This PR alone does not add a Pages route.

The owner requested one new integration PR against master. Preserve this implementation and #267 as provenance there; do not reimplement the report or close this PR before the integration is accepted. COMMENT-only solo review: no self-approval and no merge performed.
