Bound nursery, bioleaching and FOS graph evidence (batch 39)

[realmarcin]

Scope

Existing-graph evidence corrections for nursery inoculation, e-waste bioleaching and a FOS gut-liver model. Corpus: 157 reviewed / 294 pending / 9 needs_research across 460 records in both roots.

Closes #1445. Closes #1446. Closes #1447. Non-graph #1448/#1449 and graph expansion #1450 remain open.

Changes

Nine existing nodes and three arrows retained; no new structure. Two record reviews complete; FOS remains needs_research for missing host-response structure.

Eucalyptus: prior trait screens do not measure nursery nitrogen fixation or specific IAA exchange. Root composition does not establish strain persistence or robust taxon displacement. Host quality is genotype-dependent, and the operational dead category includes severe stem curvature. Remove categorical colonization facilitation/mutualism and preserve earlier workflow-arrow removals. Explicit participants name inoculant/host context, not an exhaustive root microbiome.

E-waste: retain the actual FeIII/FeII chemical-biological feedback, with causal descriptions replacing subculture-workflow narration. Remove syntrophy/competition and inappropriate transport/carbon-fixation annotations. Faster oxidation lag did not accelerate the seven-day batch metal-dissolution endpoint. Separate solid-PCB stirred-tank concentrations from equivalent-leachate toxicity flasks; no universal above-8% threshold or measured genetic adaptation.

FOS: distinguish DNA-qPCR abundance from RNA/cDNA expression and qualitative GC-MS from flux/yield. Actual Figure 7 labels propionate in minimal-core B, not separately in whole-community C; remove its whole-specific assignment without claiming physiological absence. Keep canonical strains, #1206 role corrections and the prior active-metabolite gap. Extract pretreatment precedes palmitate challenge; missing host-response structure remains #1450, without an invented active mediator or Cd36 mechanism.

Verification And Output Records

415 passed in 182.97s (0:03:02); eight new regression tests. Focused schema, strict, term, snippet and history checks passed. All three reference-validator invocations exit 0 but perform zero checks: a no-op, not evidence validation. Textual snippet matching is not scientific validation.

Zero structural errors, all 33 baseline warnings exactly preserved. Eucalyptus added to participant registry (184 to 185); connectivity census and numeric bounds unchanged. Nine nodes and three arrows unchanged in count.

Guarded writes and append-only histories; non-graph raw blocks, 457 other records and 920 caches byte-preserved. Repeat renders deterministic and exact published descriptions checked across 456 pages. Actual post-commit just check-docs-current exited 0 with clean tree; output log SHA256 7a6f19a2ddd2aad2ae1a760ca0e31fa727e68cd5a8ccd38acbc2180b266760bc.

Committed decisions, actual validation outputs/baseline/digests and self-adversarial review are under reports/causal_graph_review, dated 20261006, batch39. Full cached primary main bodies reviewed for all three records; actual FOS Figure 7 visually inspected. No other visual figures, separate supplements or raw-data review claimed.

FOS one-community Edison dry run completed (13,999 characters); no provider job or charge. Specific authorization requested. This is source-based self-adversarial review, not independent approval.

Dependency

Draft depends on #1444; 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 b11357ff0804eeed7bb20f27e7a10adb39a8614f. Not independent approval.

Integrated already-merged schema prerequisite #1692 (67603e192525899fae75420e2c19e8212b16afc9). Compared with the prior reviewed head 3f0c4de3c381ae1f6e627c8d0825d148c49be7e9, 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 9091176fe29205c10009cb13ee882fb2582b2d21ac8a381b93e0546e5292e861). 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 a44424146355d55d0024cbe6d8ec33aaf963b12a. This is a COMMENT, not independent approval.

Integrated already-merged main PR #1730 (fe1752572a688051e8105e5b89d3099fe2202c63). Compared with prior reviewed head 788e12099bf1752d5f3c1bd42c09667d3d3d5e49, 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 9091176fe29205c10009cb13ee882fb2582b2d21ac8a381b93e0546e5292e861). 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. This PR's reviewed source head d45a7fdbfa63580b3ff59abd40d6656d376b79f8 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.
