+# 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.
