Bound pit-lake, bioleaching and milk-biofilm causal claims (batch53)

[realmarcin]

Scope

Closes #1506. Closes #1507. Closes #1508.
Related #1509 remains OPEN for industrial exact-system identity, roster and valid regeneration structure; this PR does not resolve it.

• Bound site-specific pit-lake findings and remove three unsupported causal arrows.
• Correct bioleaching organism and study assignments; preserve unresolved community identity and regeneration graph.
• Preserve thiocillin genetic effects with explicit participants and condition-specific perturbation scope.

Adversarial Review

• Whole796-line Iberian,1174-line industrial and373-line milk records reviewed, including every original node and arrow. Complete cached2013/2020 pit-lake and2021 milk primary main texts, Methods, embedded tables and captions read. Fresh2023 industrial primary XML main text, Methods, Tables1-5 and captions read. No original figure images, external supplements, raw data or code audited.
• Cueva de la Mora2022 and chalcopyrite2014 bodies remained inaccessible; their primary abstracts were read, not full texts. Separate2009/2019 consortia, Acidiplasma genome and borehole studies were read at abstract scope. The Cuniculiplasmataceae review is background, not primary reactor evidence.
• Iberian NSC/Concepcion, Cueva de la Mora, FC/La Zarza and borehole findings remain distinct. Measured geochemistry and observed FC mineral particles are retained as positive evidence; biosulfidogenesis and taxon assignments remain models. Precipitated sulfides are not described as dissolved sulfides. No exact concentrations or mineral identity are transferred across lakes.
• Active Coccomyxa dominance is preserved without a quantified carbon-export rate. FC/La Zarza findings do not establish universal carbon limitation. Rare methanogen reads are not measured methane flux. Sulfide oxidation is assigned to the predicted archaeal role, not sulfate reduction; unrelated iron-transport and TCA annotations removed.
• Three Iberian arrows represented coactivity, reversed carbon-consumption direction or an unmeasured archaeal donor route. All five nodes remain with explicit canonical participants. No new graph node or arrow is introduced.
• Industrial early A. caldus and middle S. acidophilus population observations remain positive findings. A. caldus is not assigned ferrous-iron oxidation or rusticyanin. The previously omitted rather-than negation is restored. Copper extraction of60.4 percent at20 percent pulp density after more than two years of adaptation remains, supported by the result rather than a Methods snippet.
• F. thermophilum in2014 is not substituted with2023 F. acidiphilum/Acidiplasma genomes. The retained copper-output participants are explicitly a supported subset, not the complete roster. Leptospirillum nondetection is not extinction or an isolated toxicity experiment. Genomic metabolic potential and Ferroplasma co-detection do not prove partner benefit or complementarity.
• The2023 reactor profiles retain positive temperature associations with single-run, relative-abundance and operating-condition limits. Three invalid/cross-study industrial arrows removed; nine nodes remain. Canonical taxonomy and non-graph claims preserved, not certified. Issue1509 remains unresolved for exact-system identity, roster and valid regeneration structure.
• Milk retains both positive causal arrows grounded in the tclE-H deletion and omission experiments. About50-fold Kocuria change is preserved. Genetic evidence is not purified-thiocillin rescue; activity was mainly pellet-associated or unstable. The72-hour establishment comparison is not a mature-biofilm recovery time course or universal resistance to strong continuous changes.
• Milk strain-label variation is not silently normalized: canonical CLL49 remains. The Bacillus reference-culture substitution and prior529 cultivation-arm repair are preserved. No unsupported pairwise interaction categories remain on community nodes.
• Full record diffs, all eight new tests, cache appendix and participant-registry diff inspected. Seventeen nodes retained; six arrows removed and two retained. Only graph, discussion and curation-history record fields changed.457 other records and raw non-graph blocks preserved.919 caches unchanged; one abstract gains24 source-verified words with exact XML hash, context and CC BY attribution; its original bytes remain an exact prefix.
• Actual schema, strict, term, reference, snippet, rank and history gates passed. Network equals baseline with34 existing findings and no structural errors. Repeat renders deterministic; exact descriptions across456 pages parser-checked, not browser screenshots. One participant registry entry added; measured connectivity census unchanged. Post-commit docs-current is a separate publication gate.
• Dedup searched813 all-state issue titles/bodies and20 ignored/hidden local files, with relevant matching contexts inspected, not every historical comment/review.1506/1507/1508 addressed but remain open until protected-main merge.1509 remains unresolved. This source-based self-adversarial review is not independent approval.

Verification And Output Records

Self-adversarial integration review at exact head 39aed2372cf52b330c4e8d299096e88d6111737f. Not independent approval.

Integrated already-merged schema prerequisite #1692 (67603e192525899fae75420e2c19e8212b16afc9). Compared with the prior reviewed head 807c7c414ee0023c0272da510ff7619db886a0de, 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 f9fb85d489ff584c5c676b04f84f29e8e4f093b981c2f1b6ac0f853ecec11397). 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 89942aa81c6dc3fbf19de5c437c07aad9c431b77. This is a COMMENT, not independent approval.

Integrated already-merged main PR #1730 (fe1752572a688051e8105e5b89d3099fe2202c63). Compared with prior reviewed head 8d816cb2da1beb540682bd1fa111fe5eb50633e7, 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 f9fb85d489ff584c5c676b04f84f29e8e4f093b981c2f1b6ac0f853ecec11397). 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 76dd8c0d9dced4f9941719411ff5acd626476594 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.
