+"""Freeze a source-free observed-live dependency closure for Darwin/Rachinsky ``{{ВАР}}``.
+
+This contract follows the independently reviewed provider-drift guard. It binds the
+exact revision IDs observed for the template root and the load-time Lua closure used by
+the retained Darwin mainspace path, while failing closed because MediaWiki revision
+SHA-1 identities could not be retrieved from the provider API in this execution
+environment. It does not claim historical transclusion, a full Scribunto replay, or a
+render-profile promotion.

+# Darwin/Rachinsky 1864 — `{{ВАР}}` observed-live snapshot closure
+
+This source-free companion narrows the unresolved Darwin/Rachinsky `{{ВАР}}` replay to one explicit provider snapshot observed on **2026-09-24**. It is a replay-preparation artifact, not a historical-transclusion claim and not a renderer promotion.
+
+The observed root/load chain is:
+
+`Шаблон:ВАР@3684602` → `Модуль:Дореформенная орфография@5721277` → `Module:Header@5746249` → `Module:BEED@5746253` + `Module:Util@5750249`; loading BEED also loads `Module:RomanNumber@3684553`.
+
+The template root delegates to the orthography module. The orthography module loads Header for `parse_title(..., "isPRS")`. At Header revision `5746249`, module initialization loads BEED and Util; BEED initialization in turn loads RomanNumber. Source inspection keeps function-body-only dependencies such as `Module:Header/Data`, `Module:BEED/scans`, `Module:BEED/lists`, `Модуль:Math`, and `Модуль:Отексте/ЭСБЕ` outside this candidate's observed load-time path because the retained Darwin replay reaches only Header's title classifier.
+
+The revision-ID topology is now explicit, but the identity gate remains closed. The current execution environment could not retrieve MediaWiki `rvprop=sha1`, so none of the six revisions is claimed SHA-1-frozen. Therefore `mediawiki_sha1_complete=false`, `replay_ready=false`, and no full `{{ВАР}}` invocation has been replayed.
+
+The machine-readable contract is [`source-edition-traces/darwin-origin-species-rachinsky-1864-ru.var-live-snapshot-closure-evidence.json`](source-edition-traces/darwin-origin-species-rachinsky-1864-ru.var-live-snapshot-closure-evidence.json), SHA-256 `245f77bf3d99d6610ca5fbbe4fcdcdb4ef68bebca612c5bb81db6c2d77f26509`.
+
+`ВАР` remains unresolved at **388 invocations**. The effective backlog remains unchanged at **4 tag shapes / 130 tag tokens** and **37 template shapes / 2,356 template invocations**. Historical transclusion, an offline/version-pinned Scribunto runtime, complete renderer/body identity, `>=300k` admission, FantLab analyzer-input identity, and M2 parity all remain open.
+
+The next step is mechanical and deliberately separate: acquire MediaWiki SHA-1 for exactly these six revisions, then perform a bounded full candidate invocation replay without substituting later live descendants.

+## 2026-09-24 — Darwin `{{ВАР}}` observed-live snapshot closure candidate
+
+- Selected SCRIP-CORPUS-083 / Issue #255 from the normal-flow P2 corpus queue after confirming no interrupted/open PR or issue recovery work.
+- Re-checked official Russian Wikisource provider state and bound one explicit observed-live replay topology: `Шаблон:ВАР@3684602` -> `Модуль:Дореформенная орфография@5721277` -> `Module:Header@5746249` -> `Module:BEED@5746253` + `Module:Util@5750249`, with BEED loading `Module:RomanNumber@3684553`.
+- Distinguished load-time dependencies from latent function-body-only dependencies (`Module:Header/Data`, `Module:BEED/scans`, `Module:BEED/lists`, `Модуль:Math`, `Модуль:Отексте/ЭСБЕ`) not reached by the retained Darwin `parse_title(..., "isPRS")` path.
+- The provider API route needed for `rvprop=sha1` was unavailable from this execution environment. The new source-free contract therefore binds revision IDs/topology but keeps all six `mediawiki_sha1` values null, `mediawiki_sha1_complete=false`, and `replay_ready=false` instead of manufacturing identity evidence.
+- Evidence SHA-256: `245f77bf3d99d6610ca5fbbe4fcdcdb4ef68bebca612c5bb81db6c2d77f26509`.
+- Added deterministic reconstruction/validation plus five focused regressions and a public source-free companion. No source prose is committed.
+- `ВАР` remains unresolved at 388 candidate invocations. Effective backlog remains 4 tag shapes / 130 tag tokens and 37 template shapes / 2,356 template invocations. Historical transclusion, offline/version-pinned runtime, complete renderer/body, >=300k, FantLab-input and M2 gates remain closed; M2 stays 0/5.
+- The next evidence step is mechanical: obtain MediaWiki SHA-1 for exactly the six bound revisions, then run a separately bounded full candidate invocation replay. This authoring run does not self-review or merge its substantive PR.

Fresh Russian Wikisource evidence independently corroborated `Модуль:Header@5746249` as a 2026-09-10 revision, the 2026-09-08 forum warning as provider-drift risk rather than a proven outage, and the pinned `Модуль:Дореформенная орфография@5721277` dependency on Header title classification.

All 22 PR-triggered workflow runs for the exact head completed `success`; frozen-diagnostic run `35979105385` checked out that exact SHA and both jobs completed their standard-library and replay steps successfully.

+# Run receipt — SCRIP-CORPUS-083
+
+Status: REVIEW_PENDING
+
+## Orientation
+
+- Connected GitHub identity: `andy-zen-dev`.
+- Repository: `drevendev/Scriptorium`; write permission available.
+- Exact authoring base: `ee57313a6974abd326311a7b70f010ae647781a2`.
+- Issue: #255.
+- Draft PR: #256.
+
+## Produced
+
+- Source-free observed-live `{{ВАР}}` replay-snapshot closure for the retained Darwin/Rachinsky candidate.
+- Exact observed revision-ID topology: `Шаблон:ВАР@3684602` -> `Модуль:Дореформенная орфография@5721277` -> `Module:Header@5746249` -> `Module:BEED@5746253` + `Module:Util@5750249`; BEED -> `Module:RomanNumber@3684553`.
+- Explicit separation of load-time dependencies from latent function-body dependencies that are not reached by the candidate `parse_title(..., "isPRS")` path.
+- Deterministic contract builder/validator, five focused regressions, and a public source-free companion.
+
+Evidence SHA-256: `245f77bf3d99d6610ca5fbbe4fcdcdb4ef68bebca612c5bb81db6c2d77f26509`.
+
+## Research evidence
+
+- Current Russian Wikisource `Шаблон:ВАР` remains revision `3684602` and delegates to `Модуль:Дореформенная орфография`.
+- `Модуль:Дореформенная орфография@5721277` loads `Module:Header` and uses `header.parse_title(..., "isPRS")` on non-Page namespaces.
+- Current `Module:Header@5746249` loads `Module:BEED` and `Module:Util` at module initialization.
+- Current `Module:BEED@5746253` loads `Module:RomanNumber`; current `Module:Util@5750249` and `Module:RomanNumber@3684553` expose no additional load-time module dependency in the observed source.
+- The environment's direct MediaWiki API route for `rvprop=sha1` was unavailable, so revision IDs are recorded but SHA-1 identities are deliberately not invented.
+
+## Evidence boundary
+
+`revision_ids_complete=true`, but `mediawiki_sha1_complete=false` and `replay_ready=false`. All six `mediawiki_sha1` fields are null. Historical transclusion is unproven; no offline/version-pinned Scribunto runtime is established; no full candidate `{{ВАР}}` invocation is replayed; no render-profile or backlog promotion occurs. `ВАР` remains unresolved at 388 invocations and effective unresolved counts remain 4 tag shapes / 130 tag tokens and 37 template shapes / 2,356 template invocations. Literary-body identity, >=300k admission, FantLab analyzer-input identity and parity remain closed; M2 stays 0/5.
+
+## Verification performed in authoring run
+
+- Official provider pages/search evidence were re-read for the six revision IDs and their load relationships.
+- The evidence contract was generated from the same deterministic structure used by the committed builder; its self-digest is pinned above.
+- Substantive changes were left in Draft PR #256 for later independent exact-head review. This authoring run did not approve or merge its own work.
+
+## Next action
+
+Independently re-read all changed files and exact-head CI for PR #256. If clean, mark Ready and merge with expected-head protection. Only after that, in a separate bounded unit, acquire MediaWiki SHA-1 for exactly these six revisions before attempting a full invocation replay.
