Bound enrichment and host-response causal claims (batch86)

[realmarcin]

Scope

Closes #1711.
Closes #1712.
Closes #1713.
Closes #1714.
Research #1715 and non-graph #1716 remain OPEN after repair merge.

• Retain positive 91.97% degradation without obligatory syntrophy.; Retain proposed metabolic products/pathways with attribution and metabolomics limits.
• Preserve positive enrichment reduction and qualify Polaromonas/MAG attribution.; Preserve controlled enrichment precipitation without invented mineral or partner details.
• Preserve positive physiological responses and qualify their causal mediation.; Preserve recruitment association and qualify its host-benefit interpretation.; Preserve formulation-specific host growth without collapsing alternative communities.
• Retain author-proposed complementarity with explicit mechanistic and inoculum uncertainty.; Preserve positive maximum power comparison within the tested model substrate.; Preserve reported COD endpoint while exposing primary-source arithmetic discrepancy.

Adversarial Review

• Fresh two-root baseline preceded papers; whole four records and all18nodes11arrows reviewed. Retain10nodes5existing directions, remove8nodes6directions, add no topology. Every original node/arrow has a disposition.
• Pleuromutilin91.97%degradation remains positive. Natural En4 diversity/enrichment is preserved as parent context rather than assigned to five selected strains. Isolation/assembly are workflow, not niche partitioning. Proposed products remain HYPOTHESIZED without obligatory syntrophy or metabolite provenance assumptions.
• Pleuromutilin public TableS2 no-inhibition assay is not cross-feeding/stable coexistence. TableS1 distinguishes W12 from same-species W10 and bacterial/fungal pool from abstract14bacteria. No unreviewed new compatibility/pathway topology;1715remains needs_research and1716identity follow-up staysopen.
• Vanadium public FigureS2 supplies positive controlled precipitation evidence, so reduction-to-precipitation survives at enrichment scale. Polaromonas and MAG reductase attribution remain PARTIAL, not isolate/gene necessity. No invented exact kinetics, mineral phase, reciprocal mutualism or arrA function.
• Desulfovibrio/Desulfitobacterium sulfide and Geobacter sequential-iron nodes lack reviewed exact-system support and are removed. Only Polaromonas receives explicit community credit. Three disconnected canonical taxa are exposed, not silenced;51warnings includes three new DISCONNECTED entries, zero structural defects. Source Hunan locality and Acidithiobacillus citation mismatch remain non-graph1716.
• Populus retains positive host physiology, root recruitment and growth plus two PARTIAL biological explanations. Three workflow arrows removed. Host evidence IN_VIVO, alternative SynCom5/7/9 formulations not one combined culture. No claim of mediator intervention or inaccessible full-text/supplement review.
• Poultry maximum170mW/m2positive comparison survives, not every-time-point superiority. Both complementarity arrows remain HYPOTHESIZED and niche-partitioning labels are removed. SEM morphology does not establish interspecies electron transfer. OD-normalized source wording leaves total inoculum-volume ambiguity.
• Poultry reported84.4%COD remains with explicit primary arithmetic conflict:2150to436is79.7%,2150to335is84.4%. No silent swap, exact ranking certification, native-wastewater mineralization or scale-up claim. Amended/sterilized matrix and aggregate COD limits retained; non-graph1716staysopen.
• Source access distinguishes three abstracts without main text, one full poultry main text, read-only DOCX tables/method note, structured XLSX parsing and ten visually inspected vanadium PDF pages. No paywall bypass or claim that all annotation/metabolomics rows were manually reviewed. Public SI source URLs and original hashes preserved.
• 456otherrecords,920othercaches and raw non-graph blocks preserved; one provenance-labeled public FigureS2 caption appended, abstract-only main-source metadata unchanged. Four append-only histories, concrete curation events and ten focused tests. Required local gates and deterministic HTML-description checks actually executed, not browser screenshots.
• Dedup984issues and65ignored/hidden local matches with declared exclusions;1680read, comments/PRs not exhaustive. One scoped Edison dry run11100characters, no paid job. Repair1711-1714close after protected-main merge;1715/1716remainOPEN. Exact-head self-comment is not independent approval; corpus and loader1703remain unfinished.

Verification And Output Records

776 passed in 260.37s (0:04:20); ten new focused tests. Four schema/strict/term/reference/snippet/history gates passed. Four full-record reference validators exit0. CLI Total checks counts issues, not executed checks. Eleven graph and eight discussion quotations independently match primary sources and cache text; matching is not scientific entailment. Vanadium FigureS2 is a separately labeled public supplement, not main-text access. Other source limits remain explicit.

All18originalnodes11arrows reviewed;10nodes5qualified directions retained,8nodes6directions removed,no new topology. Preserve positive degradation, controlled precipitation, host responses and MFC power. COD source discrepancy explicit. Three newly exposed DISCONNECTED taxa produce51warning entries; zero structural defects. Metadata #1716 remains open, not false community credit.

456otherrecords,920othercaches and raw non-graph blocks unchanged. One provenance-labeled public Supplement FigureS2 caption appended; main source remains abstract-only. Deterministic rendering and exact HTML-description parser checks, not browser screenshots. Full both-root snippet audit informational, not clean-corpus certification. Separate generated-model loading defect #1703 unresolved.

Postcommit check-docs-current passed clean, SHA256 41a63fd283f77bd90f2914af88541c9e513b4ab04979817407b78a7c46d7347c.

Source Limits

• Fresh before-paper baseline includes both roots:460records921caches,1433nodes592arrows,48warning entries and zero structural defects. All18originalnodes11arrows reviewed;10nodes5arrows remain without new topology.
• Preserve positive91.97%pleuromutilin degradation and proposed products. En4 parent findings retained as context; workflow and unsupported syntrophy removed. Compatibility/pathway expansion1715remains needs_research.
• Public vanadium FigureS2 supports reduction-to-precipitation at enrichment scale. Only Polaromonas explicitly credited; genomic attribution is partial, other partner claims removed. Newly exposed disconnected canonical taxa are a metadata gap1716, not silently credited by community scope.
• Populus physiological and recruitment explanations retain two PARTIAL biological arrows, with IN_VIVO host evidence and alternative formulations distinguished. Full mediator methods unavailable.
• Poultry retains two HYPOTHESIZED complementarity arrows and positive maximum power, with model-matrix limits and source COD arithmetic/inoculum ambiguity exposed. Reported84.4%is not silently corrected or certified.
• One cache gains a clearly labeled public Supplement FigureS2 excerpt with source/PDF hash; main-article abstract-only status remains accurate. Other920caches,456otherrecords and raw non-graph blocks preserved. No taxonomy or auditor-rule changes.
• Four primary abstracts inspected; poultry main text read. Source access scopes distinguish abstracts, main text, extracted tables and visual PDF pages. No full-text claim for paywalled sources; no access bypass.
• Dedup984all-state issue titles/bodies and65ignored/hidden local matches with explicit .git/docs/site/references_cache exclusions. Related1680read; comments/PRs not exhaustive.
• One-community Edison causal dry run11100characters; scoped paid question unanswered, zero provider jobs/credits. Earlier pending/denied scopes unchanged. Repair1711-1714close only after protected-main merge;1715/1716remainOPEN.
• Validation and rendering are separate actual gates, not preasserted. Self-adversarial review is not independent approval, whole-record certification or corpus completion. Generated-model loading defect1703remains unresolved.
• Final diff check caught trailing whitespace in the original supplemental caption extraction. Cache appendix was shortened to a four-word fragment plus paraphrased context and explicit archive/download/license links. Graph records/history unchanged; affected checks and broad regressions rerun, with original outputs retained as superseded.

Dependency

Draft depends on #1710. Do not merge into the topic parent. Require exact-head CI and protected-main queue after parent merge. Move dependents before deleting parent branches.

Self-adversarial review refreshed at exact head 5775ff59ef6d18aada7c23267871b5ce14eb9e45
after protected main merge of #1361. This is not independent approval.

The entire tree remains identical to the preceding reviewed tree 1f4a0e3cda1ea8054239e14db2bd1df3d081df67.
The batch-owned binary patch is byte-identical
(SHA-256 35cbbb6e97e1e5d6658272a177d0eed79a5c142a971325b86c8d8f5e831ecf43); only ancestry changed.
Scientific records, caches, source-review output, histories, regression tests, and generated pages
are unchanged. Historical validation results and recorded source/access limitations therefore
remain applicable, but required CI must pass at this new head. No new source review or local test
rerun is claimed by this ancestry-only update.

The protected main queue remains mandatory. Keep dependents on their reviewed parent until that
parent is confirmed merged; move dependents before deleting merged branches.

Self-adversarial governance integration review at exact head 1357d744c146ae94e37306742991538b2fb5b563. This is a COMMENT, not independent approval.

Integrated already-merged main PR #1730 (fe1752572a688051e8105e5b89d3099fe2202c63). Compared with prior reviewed head 5775ff59ef6d18aada7c23267871b5ce14eb9e45, 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 35cbbb6e97e1e5d6658272a177d0eed79a5c142a971325b86c8d8f5e831ecf43). 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.

Exact-head self-adversarial restack review at 85f35e204061c822bd762ea53016a705a92ef428.
COMMENT, not independent approval.

The batch-owned binary patch remains byte-identical:
SHA-256 35cbbb6e97e1e5d6658272a177d0eed79a5c142a971325b86c8d8f5e831ecf43.
Tree 01e13ea0a05371b54b55abd7a64dc4f97037065d matches the independently computed clean merge.
Compared with historical tree a4eb437d61dbc99484a5c711efd11bea5135868e, only scripts/.vendored_canon_ref
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.

[realmarcin]

Superseded by the protected cumulative merge #1975 at 42959bef2549f9a42c3e3303a0e10fd5be99f30e. This PR's reviewed source head 923cf79cb7511f18108fd7cbc45d71856d56b2b6 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.
