Bound fucoidan, GENIA and Transwell graphs; correct review counter interpretation (batch 42)

[realmarcin]

Scope

Existing-graph corrections, explicitly pending expansion and a review-output correction. Corpus: 163 reviewed / 285 pending / 12 needs_research across 460 records in both roots.

Closes #1466. Closes #1469. #1465/#1467/#1468 remain open. #476/#1362 are not resolved.

Changes

Seven existing nodes retained, one generic platform node removed; one PARTIAL arrow retained and one workflow arrow removed. Three GENIA nodes renamed. No new causal structure.

Fucoidan: experimentally supported monomer specialization, canonical seven-strain panel, five-member 97.1% maximum and null-model functional synergism. Cleavage/uptake is not CO2 mineralization, reciprocal fitness benefit or obligatory small-molecule exchange. Preserve G88 exclusion and per-strain inoculum caveat. Publisher DOM resolves V4 plus superscript reference 3, not a V43 biological alias. Complementary-accessibility causal expansion remains needs_research under #1465.

GENIA: separate computational complementarity from reported removal and DNA composition. Distinguish higher separate-treatment figures from lower mixed-pollutant results. Remove the assembly workflow arrow and unsupported mutualism/niche categories. Retain only a PARTIAL daily ratio-management-to-removal arrow, with handling confounding and nonsignificant lignin comparison explicit. Source mass-balance contradictions and non-graph overclaims remain #1468.

Transwell: remove the generic platform umbrella and keep AHL reporter versus three-member metabolomics assays separate. Nonpolar mass features are not identified metabolites or resolved exchange flux; polar bactobolin accumulation is not selective inhibition mediation. Exact strain identities, a bounded antagonism node and assay metadata remain needs_research under #1467.

Two separate one-community Edison dry runs completed and are preserved with query hashes (15,343 and 8,368 characters). Specific credit authorization requested; no provider job or spend. Existing-node corrections are not completed expansion.

Verification And Output Records

440 passed in 203.92s (0:03:23); nine new regression tests. Schema, strict semantics, term and history checks passed. 66 snippets MATCH cached text; GENIA retains nine baseline RENDERING classifications. Fucoidan also has 15 unchanged MISMATCH findings, reproduced byte-for-byte at baseline (14 taxonomy excerpts plus one discussion excerpt present in the separate supplement sidecar). No all-MATCH result is claimed. Matching is not scientific validation or independent cache provenance.

Reference CLI: Fucoidan exits 1 with 14 unchanged taxonomy findings, reproduced byte-for-byte at the pre-edit head. All 14 snippets match its separate supplement sidecar, which the installed fetcher does not combine with the article. No clean reference pass or original-spreadsheet verification is claimed. GENIA and Transwell exit 0.

Correction #1469: earlier reports misread Total checks: 0 as a no-op. Installed 0.1.7 counts reported issues, not executed checks; five existing positive/negative/discovery canaries pass. A prominent README and correction receipt preserve installed-code evidence, initial failed attempt, baseline comparison and 24 historical candidate files. Prior raw reports remain unchanged. SupportingReference #476 and selected-excerpt trust #1362 remain open.

Zero structural defects; all 33 baseline network warnings preserved. Participant registry 187 to 189 with unchanged connectivity census/bounds. Guarded writes, append-only histories, 457 other records and all 920 caches unchanged. Repeat renders deterministic; exact published descriptions checked across 456 pages.

Actual post-commit just check-docs-current exited 0 with a clean tree; output SHA256 ff0768cd900b27cbf306b0e72be665829287d475678491e87c21fc3c42755717. Decisions, actual validation outputs, correction and source-based self-adversarial review are committed under reports/causal_graph_review, batch42.

Source limits: all three primary main bodies and Methods read with explicit public/cached source scopes; no figure images, separate supplements or raw data independently inspected. Fucoidan Table 2 selected cache rows are not original-spreadsheet verification. No access-control bypass. This is self-adversarial review, not independent approval.

Dependency

Draft depends on #1464; do not merge into the topic parent. Require eligible exact-head checks and the protected main queue after parents merge. Move dependents before deleting branches. Full-corpus completion is not claimed.

Self-adversarial integration review at exact head ca0624a28b7a5229870b228d4a4dfbd821eac580. Not independent approval.

Integrated already-merged schema prerequisite #1692 (67603e192525899fae75420e2c19e8212b16afc9). Compared with the prior reviewed head f820d8386ba8c85aa6cba00879e4ec37225d4242, the only changes are the canonical schema pin, shared schema and generated datamodel from that main commit. Every other tracked file is identical; the batch-owned binary patch remains byte-identical (SHA-256 34b1cc9b340ba39687800f1cf6766763e569acb9a24ab69017fb134c59113310). All 60 published batch patches were checked this way. No scientific assertion, reference cache, history, decision ledger or generated page was edited by this integration.

Adversarial checks: no inherited schema-file edits lost; generated CrossCorpusLink remains standalone and does not add a causal claim; normal strict validation passed all 460 records; required CrossCorpusLink fields enforced. Fresh broad regression runs on both ends of the stack: 302 passed in 172.77s (0:02:52); 756 passed in 255.55s (0:04:15). Docs-current passed clean at batches25/84, and vendored-sync passed. The 58 intermediate combinations were not independently retested. Existing primary-source review limitations and unresolved research issues remain applicable; historic validation receipts are not rewritten as new scientific reviews.

An additional generated-datamodel loading check FAILED and is retained in the integration receipt. Differential testing found exactly the same failures on all 460 paths before and after this integration:417 unhashable TaxonDescriptor and43 unhashable CultureCollectionEnum exceptions, with linkml-runtime1.11.1. Existing tests explicitly use plain YAML instead of this loader. Pre-existing defect #1703 remains OPEN; no datamodel-loader success is claimed. Normal strict schema validation is a separate passing path, not a relabeling of that failure.

Required CI must pass on this exact head and the protected merge-queue candidate. No manual workflow dispatch, artificial status, administrative merge or protection bypass. Dependents stay draft until their parent is confirmed merged; move dependents before branch deletion.

Self-adversarial governance integration review at exact head cfc81e8c8af252fde3de5f44e92e943c23c5b08d. This is a COMMENT, not independent approval.

Integrated already-merged main PR #1730 (fe1752572a688051e8105e5b89d3099fe2202c63). Compared with prior reviewed head 866af5c2120d1d1a8930c91f2416634ac925ca5a, exactly two files changed: scripts/.vendored_canon_ref and tests/test_id_label_empty_adapter.py. Each resulting tree differs from its old tree by the exact binary patch from main, and each batch-owned binary patch remains byte-identical (SHA-256 34b1cc9b340ba39687800f1cf6766763e569acb9a24ab69017fb134c59113310). These invariants passed on all 74 published branches. Original heads are retained in local archive refs/archive/communitymech-pre-governance-20261007. No scientific record, source cache, history, decision ledger, schema, runtime code or generated page changed in this integration.

Adversarial inspection: the adapter regression still checks the empty sentinel and case-insensitive caching, now with an isolated fake oaklib module and a one-call selector assertion. No validation threshold or runtime behavior was relaxed. Fresh regressions at both stack ends: 337 passed in 214.19s (0:03:34); 917 passed in 402.58s (0:06:42). Docs-current and pinned vendored-sync passed at batches26/99. The 72 intermediate combinations were checked by tree/patch hashes, not independently retested. Historical source-review limitations and unresolved issues, including loader #1703 and cache #1091, remain applicable. This is not new paper review, independent approval, or a claim that those outstanding issues are fixed.

Digest-bound integration receipt/logs: /private/tmp/communitymech-governance-integration-20261007/receipt.json. Prior output/review records in reports/causal_graph_review/ remain unchanged. The prior lifecycle receipt is archived and will be updated only after all exact-head comments are verified.

Required CI and independent review must pass for the exact head and protected merge-queue candidate. No CI rerun, manual dispatch, fabricated status, admin merge or protection bypass. Dependents remain draft; move them before deleting a merged parent branch.

COMMENT, not independent approval.

The batch-owned binary patch remains byte-identical:
SHA-256 34b1cc9b340ba39687800f1cf6766763e569acb9a24ab69017fb134c59113310.
Tree 3b9bd418546644ed38e36bce7a552465a9ea9176 matches the independently computed clean merge.

changes, incorporating main PR #1834's pin 849f336e025510316a5f235eb0af8547b8bd50cc.
All curated records, source caches, review outputs, histories, regression tests, and rendered
pages remain unchanged. No new primary-source review or local scientific-test rerun is claimed.

This PR is now part of native stack #1973, rooted at #1363 on main. No protected merge
has occurred. Fresh eligible PR/merge-group CI remains mandatory. No rule bypass, fabricated
status, merge into a topic parent, or premature branch deletion.

Superseded by the protected cumulative merge #1975 at 42959bef2549f9a42c3e3303a0e10fd5be99f30e. This PR's reviewed source head 19f27f1cc4f7c1fa4cd8c1ef0a10c28d0dc23a8f was included in the cumulative branch; the final squash tree matches the reviewed integration tree exactly, and all seven required merge-group checks passed.

Patch-inclusion receipt. Existing issue-closing links were transferred to #1975; unresolved research and non-graph gaps are not closed by this action. This PR is being closed as superseded, not represented as individually merged. Archival provenance tags retain source commits; cleanup removes branch refs only and preserves worktree files.
