Qualify polymer, groundwater and microalgal causal mechanisms (batch 38)

[realmarcin]

Scope

Existing-graph repairs for polymer degradation, groundwater episymbiosis and microalgal production. Corpus: 155 reviewed / 297 pending / 8 needs_research across 460 records in both roots.

Closes #1438. Closes #1439. Closes #1440. Non-graph #1441/#1442/#1443 remain open.

Changes

Twelve existing nodes retained; three part-to-summary arrows removed, and all three remaining mechanism links explicitly HYPOTHESIZED. No added connectivity or Edison job/charge.

Ensifer/Sphingobacterium genomic complementarity remains a conceptual donor/recipient model, not direct carbon flux or enzyme necessity. Comparative polymer output is not reciprocal fitness or formal additive synergy. Surface endpoints do not demonstrate complete mineralization. Preserve AMBIGUOUS Ensifer grounding and exclude MF1 from membership.

CPR/DPANN is an eight-site groundwater framework, not a defined three-member culture. Size fractions and modeled cell counts are proxies; imaged ultrasmall-cell taxonomy is inferred. The attachment-to-iRep link remains a hypothesis, without an attachment intervention or measured host fitness. iRep is population replication state, and archaea were excluded. Preserve the prior three workflow-arrow removals and distinguish the separate Oak Ridge source.

Euglena and Chlorella profiles become intrinsic source-only nodes; remove both profile-to-summary arrows and the unsupported Euglena-specific alpha-tocopherol assignment. Proposed complementarity may contribute to aggregate output, but neither exact exchange nor reciprocal fitness is established. Exogenous alpha-lipoic acid is a separate treatment, not endogenous cross-feeding. Preserve the publication name and canonical Auxenochlorella taxon label.

Verification And Output Records

407 passed in 203.34s (0:03:23); eight new regression tests. Focused schema, strict, term, independent snippet and history checks passed. Three reference-validator commands exit 0 but perform zero checks: a no-op, not evidence validation. Textual matches are not scientific support.

Zero structural errors; all 33 baseline warnings preserved exactly, none added. All three records already belong to the unchanged 184-user participant registry. Euglena intrinsic profiles increase mixed scope from 123 to 124 and lower sole broad credit from 1221 to 1219; no numeric-bound changes.

Three guarded writes and append-only histories; non-graph raw blocks, 457 other records and 920 caches unchanged. Repeat renders deterministic, with exact descriptions checked across 456 pages. Actual post-commit docs-current passed with clean tree.

Committed decisions, actual validation output including baseline, and self-adversarial review are under reports/causal_graph_review, dated 20261006, batch38. CPR/DPANN primary main body through Methods was reviewed; Ensifer and Euglena access was abstract-only. Separate Oak Ridge source read only through early Results for provenance. No visual figures, separate supplements or raw-data review claimed. Ensifer retrieval failure is not proof of a paywall: publisher indexed text labels it open access. This is source-based self-adversarial review, not independent approval.

Dependency

Draft depends on #1437; do not merge into the topic parent. Require eligible exact-head checks and the protected main merge queue after parents merge. Move dependents before branch deletion. Full-corpus completion is not claimed.

Reference-counter correction (#1469)

The earlier statement that linkml-reference-validator 0.1.7's Total checks: 0 means zero executed checks or a no-op is incorrect and withdrawn. The installed CLI prints the number of validation issues, not checks performed. Existing positive/negative and field-discovery canaries pass; EvidenceItem snippets are genuinely checked. SupportingReference coverage remains incomplete under #476. Text matching is not scientific support or independent source provenance.

The source-backed correction and historical candidate inventory are committed in #1470 at 22b5b12c2386a949d1ec4ddb1f79ee288085bd1c, under reports/causal_graph_review/README.md and reference-validator-correction-20261006-batch42.json. Earlier raw command output, source review, biological decisions and tested bytes are preserved; this notice does not claim a rerun of this PR's validation or change its biological findings. The older CLI counter is not a coverage metric.

The new Fucoidan batch separately retains 14 baseline reference-CLI failures and 15 baseline snippet-audit mismatches for supplement-sidecar excerpts. Those are not failures attributed to this older PR. This correction is self-review, not independent approval or merge authorization beyond the existing protected workflow.

Self-adversarial integration review at exact head 84c7fa27689e8009441d3e2c8a5819394a3540fe. Not independent approval.

Integrated already-merged schema prerequisite #1692 (67603e192525899fae75420e2c19e8212b16afc9). Compared with the prior reviewed head 4189f5af300979c32aad4b15f580086a1c9d9c9e, 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 2ce1e1e8af974e23fb4867904be047770ae54382869a111a960d3ad3b35d58ca). 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 f24c31d1f964ea2db899b7c460780c2269b281b4. This is a COMMENT, not independent approval.

Integrated already-merged main PR #1730 (fe1752572a688051e8105e5b89d3099fe2202c63). Compared with prior reviewed head 164be5eb2c9c5e8e496c4e0ed6ecfe3e52aa28af, 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 2ce1e1e8af974e23fb4867904be047770ae54382869a111a960d3ad3b35d58ca). 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.

Superseded by the protected cumulative merge #1975 at 42959bef2549f9a42c3e3303a0e10fd5be99f30e.
