Goal

Continuously find and repair defects and material gaps in NeqSim documentation. Each scheduled run should scan a bounded documentation batch, fix every confirmed issue in that batch, repeat validation until clean, and create or update one reviewable draft PR.

Always use the connected GitHub plugin for every GitHub read and write.

Required documentation workflow

Load and follow:

  • .github/agents/documentation.agent.md
  • AGENTS.md
  • relevant repository skills and nested instructions

The documentation agent's rules are mandatory, including Jekyll front matter, KaTeX-compatible equations, correct navigation/indexing, exact API verification, and executable tests for code examples.

The user has pre-authorized scoped branch changes and draft PR creation for this campaign through the GitHub plugin. Never push directly to main, merge, or enable auto-merge.

Defect classes

The campaign covers:

  1. Broken or misleading code

    • non-existent classes, methods, constructors, enums, or overloads;
    • wrong imports, packages, parameter types, units, gateway usage, or Java version;
    • examples that compile but fail at runtime or produce misleading output;
    • stale output values inconsistent with current NeqSim behavior;
    • incomplete snippets presented as complete programs.

  2. Broken navigation and links

    • missing internal targets, anchors, images, downloads, or notebooks;
    • case-sensitive path errors;
    • stale redirects and permanently unavailable external sources;
    • pages omitted from section indexes or docs/REFERENCE_MANUAL_INDEX.md;
    • orphaned pages and inconsistent navigation.

  3. Equation and rendering defects

    • invalid or unsupported LaTeX;
    • use of \[...\] or \(...\) rather than supported delimiters;
    • unbalanced delimiters, malformed subscripts/superscripts, escaping errors;
    • equations, tables, lists, or code fences broken by HTML/Markdown mixing;
    • missing blank lines or front matter that breaks Jekyll rendering.

  4. Technical accuracy

    • claims inconsistent with current Java implementation or tests;
    • wrong equations, symbols, signs, reference states, units, applicability ranges, or standards versions;
    • missing assumptions, limitations, validation evidence, and engineering review boundaries;
    • API descriptions that promise behavior NeqSim does not provide.

  5. Missing or weak documentation

    • recently merged public functionality with no discoverable guide or example;
    • important public APIs absent from reference documentation;
    • common engineering workflows lacking an executable end-to-end example;
    • pages that lack prerequisites, expected output, interpretation, troubleshooting, or related links;
    • duplicated or fragmented pages that should be consolidated.

  6. Quality and accessibility

    • unclear titles/descriptions, inconsistent terminology, inaccessible images, unreadable tables;
    • ambiguous code/output relationship;
    • unnecessary duplication or obsolete content;
    • spelling/grammar fixes only when they materially improve technical clarity.

Scan rotation

Rotate through these scopes so the entire documentation estate is covered repeatedly:

  1. landing pages, navigation, indexes, and internal links;
  2. thermo, fluids, phase equilibrium, and physical properties;
  3. process equipment and process simulation;
  4. engineering design, safety, DEXPI, and field development;
  5. PVT, flow assurance, standards, and gas/oil quality;
  6. tutorials, cookbook, troubleshooting, and examples;
  7. JavaDoc-facing examples, Python snippets, notebooks, images, and external links;
  8. recent merged code versus documentation coverage.

Record the last completed scope so the next clean run advances the rotation. Revisit changed pages and high-risk code examples more frequently.

Daily workflow

1. Synchronize and resume

  • Read this issue, its comments, linked PRs, current main, repository instructions, and recent merged documentation/code changes.
  • Search for an open PR linked to this campaign.
  • Maintain at most one active documentation PR.
  • If one exists, continue its fixes, CI, conflicts, and review feedback; do not open another PR.
  • Inspect other open NeqSim PRs and avoid overlapping files or conflicting documentation changes.

2. Select a bounded scan batch

Choose the next scan scope from the rotation. A batch should be large enough to find related defects but small enough for one coherent review. Freeze the paths and validation plan before editing.

Prioritize:

  1. code that cannot compile or run;
  2. technically wrong or unsafe guidance;
  3. broken internal links/navigation;
  4. broken equations/rendering;
  5. missing documentation for important current functionality;
  6. clarity and structure improvements.

Do not create cosmetic churn merely to satisfy a daily PR target.

3. Detect defects

Use repository-aware checks appropriate to the batch:

  • build the documentation site using the repository's supported workflow;
  • validate Jekyll front matter and Markdown structure;
  • check internal links, anchors, images, and index entries;
  • retry external links and distinguish permanent failures from transient 429/5xx/network errors;
  • scan math delimiters and build/render changed pages with KaTeX/Jekyll;
  • inspect the rendered changed pages when browser/rendering tools are available;
  • compare every changed code example with the actual Java source and tests;
  • compile and execute complete Java/Python examples;
  • execute relevant notebook smoke tests where supported;
  • compare recent public APIs/merged features with documentation coverage;
  • identify orphaned, duplicated, stale, or undiscoverable pages.

Every reported defect must include path, location, category, evidence, severity, and proposed verification.

4. Fix and loop

Fix every confirmed defect in the selected batch. Then rerun the complete batch validation.

Repeat:

scan → fix → build → execute examples → check links/equations → inspect render → review diff

until:

  • all confirmed batch defects are resolved;
  • site/Markdown validation passes;
  • changed internal links and anchors resolve;
  • external links are valid or their failure is documented as transient;
  • changed equations use supported syntax and render correctly;
  • every changed code example compiles and runs;
  • navigation/index updates are complete;
  • no new defect was introduced by the fixes.

If a documented API example fails, first determine whether the documentation is wrong or NeqSim contains a real regression. Prefer correcting stale documentation. Make a production-code change only when the intended API behavior is independently supported and the fix is within the PR's coherent scope.

5. Code-example verification

For Java documentation examples:

  • verify constructors and methods against current source;
  • add or update src/test/java/neqsim/DocExamplesCompilationTest.java or a focused documentation example test;
  • exercise every API call shown;
  • assert meaningful results;
  • run the focused test and appropriate broader verification.

For Python/notebook examples:

  • use the repository-supported NeqSim gateway and local workspace classes;
  • execute the example from a clean state;
  • record supported environment and expected output;
  • do not publish unexecuted notebooks or invented results.

6. Publish through the GitHub plugin

Using only the GitHub plugin for GitHub operations, create or update at most one draft PR linked to this issue.

The PR must contain:

  • scanned paths and rotation scope;
  • defects found, severity, and evidence;
  • root cause and changes;
  • exact site build, link, equation, code, test, and notebook checks run;
  • before/after behavior or screenshots where rendering mattered;
  • coverage added for future regression prevention;
  • known transient external-link failures;
  • deliberate exclusions and next scan scope.

Never merge, enable auto-merge, push to main, weaken tests, invent successful output, or claim links/rendering were verified when the required tool could not run.

Meaning of “all solved”

A daily batch is solved only when its full validation loop is clean. The overall campaign remains active because documentation and code continue to change.

Do not abandon an unresolved batch when a new day begins. Continue the same PR until it is clean and ready for maintainer review or a documented blocker requires human input. After it is merged or closed, advance to the next rotation scope.

Source/API, structure, nine internal targets, code fence, Spotless, Javadoc, CodeQL, agent-reference, Jekyll/search, and review checks passed; the mandatory Copilot gate reviewed both changed files and found no inline comments, suggested-change blocks, or Copilot-applied commits. No rendered-site artifact was available, so browser inspection was not claimed merged commit ff545d1

| D014 | 2026-07-22 | PVT laboratory-test APIs, units, technical claims, and executable CCE quick start | 9 | 9 | Final PVT repair merged as commit 9ae5ad0 through #2577 after focused #2575 was superseded and closed. The two PVT files in #2577 were identical to #2575. Exact-head validation passed PvtLabTestsDocumentationTest (2/2) and DesignFrameworkDocExampleTest (3/3) on Java 8 and 21, Windows and Ubuntu; complete suites passed with 10,650 tests on Windows Java 8/21 and Ubuntu Java 8, and 10,852 tests plus 4,671 JaCoCo-analyzed classes on Ubuntu Java 21. Pre-commit, Spotless, Javadoc, Jekyll/search, CodeQL, and agent-reference checks passed. Copilot reviewed all four final files and generated no new comments; #2575’s sole suggestion to assert an incidental parser exception remained technically rejected and documented, with no Copilot-applied commit. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2572, #2574, #2577 |

| D015 | 2026-07-23 | Thermodynamics cookbook: executable fluid, flash, property, phase-envelope, model-selection, JSON, and clone recipes | 8 | 8 | Merged as commit 44210ac through #2582 after #2578's compile regression and #2581 follow-up. Eight independent Python blocks pass with NeqSim 3.16.0. Focused Java documentation test passed 4/4 on Ubuntu and Windows Java 21; complete Java 21 suites passed on Ubuntu (10,857 tests) and Windows (10,655 tests), zero failures/errors. Java 8 Ubuntu and Windows each passed 10,655 tests with zero failures/errors (212 skipped). Documentation build/search, pre-commit, Spotless, Javadoc, CodeQL, agent references, front matter, 16 fences, anchors, 3 internal links, and the external JavaDoc target pass. Copilot reviewed both files twice on the final head with no new comments; accepted and inherited suggestions were assessed and resolved. No equations, images, notebooks, or rendered-site artifact were in scope | merged | #2578, #2581, #2582 |

| D016 | 2026-07-23 | Google Colab quickstart: clean-runtime setup, executable thermodynamic/process/phase-envelope examples, notebook labels, warnings, and external links | 6 | 6 | Merged as commit 54dd2a4 through #2583. Three Python blocks pass with NeqSim 3.16.0. Focused ColabQuickstartDocumentationTest passes 3/3 on Ubuntu and Windows with Java 8 and 21. Complete suites pass with zero failures/errors: Java 21 Ubuntu 10,860 tests (215 skipped), Java 21 Windows 10,658 tests (212 skipped), and Java 8 Ubuntu/Windows 10,658 tests each (212 skipped). Pre-commit, Spotless, Javadoc, documentation build/search, CodeQL, links, agent references, and final-head Copilot review pass; two findings were applied and resolved. | merged | #2583, commit 54dd2a4 |
| D017 | 2026-07-23 | Recent merged black-oil conversion fixes versus package documentation and executable examples | 6 | 6 | Merged as commit e701821 through #2584.

Complete suites passed with zero failures/errors: Java 21 Ubuntu 10,862 tests (215 skipped; 4,671 JaCoCo-analyzed classes), Java 21 Windows 10,660 tests (212 skipped), and Java 8 Ubuntu/Windows 10,660 tests each (212 skipped). Pre-commit, Spotless, Javadoc, Jekyll/search, CodeQL, agent references, source/API, Markdown/fence/link, and KaTeX parsing checks passed. Four Copilot findings were assessed: two applied and validated, two formatter-conflicting suggestions rejected with reasons; all threads are resolved and the final-head re-review generated no new comments. No Copilot-authored commit exists. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2584, commit e701821 |

| D018 | 2026-07-23 | Root landing page reference-manual navigation and first-level internal targets | 2 | 2 | Merged as commit 80b9682 through #2585. Final head ec01412: 42 first-level internal destinations and 6 fragment anchors resolve; front matter and Markdown/HTML structure pass; hosted documentation build/search-index, pre-commit, Spotless, agent-reference, and CodeQL checks pass. Both quick-start code fences are unchanged and Java matrices correctly skipped for the docs-only diff. Copilot reviewed three heads: two terminology findings applied and validated; one factually incorrect zero-byte challenge rejected with exact blob evidence; all threads resolved. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2585, commit 80b9682 |

| D019 | 2026-07-24 | Thermodynamics overview and fluid-creation units, model boundaries, and executable workflows | 8 | 8 | Merged as commit 5ceeeca through #2586. Source/API audit and 34 relative destinations pass; documentation build/search, pre-commit, Spotless, Javadoc, agent references, and CodeQL pass.

Complete suites pass with zero failures/errors: Ubuntu Java 21 10,866 tests (215 skipped); Windows Java 21 and both Java 8 jobs 10,664 tests each (212 skipped). Final-head Copilot reviewed 3/3 files with no comments or suggested changes; no review threads or Copilot-suggestion commits exist. The three-commit diff remained limited to the frozen three files. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2586, commit 5ceeeca |

| D020 | 2026-07-24 | Process equipment: mixer and splitter APIs, equations, pressure behavior, and executable workflows | 9 | 9 | Merged externally as commit fac89df through #2587. Exact PR head 44e628b: source/API, front matter, Markdown, 6 Java fences, 4 equations, 5 relative targets, scoped 11-commit/two-file diff, Spotless, pre-commit, Javadoc, agent references, documentation build/search, and CodeQL pass. MixerSplitterDocumentationTest passes 3/3 on Ubuntu and Windows with Java 8 and 21. All complete suites pass with zero failures/errors: Ubuntu Java 21 10,869 tests; Windows Java 21 and both Java 8 jobs 10,667 tests each. Seven inline Copilot threads and seven suppressed observations were assessed; all threads are resolved, two final-head reviews found no new comments, and no Copilot-authored commit exists. No rendered-site artifact is available | merged | #2587, commit fac89df |

| D021 | 2026-07-24 | Field-development workflow notebook, generated tutorial, and durable automatic-regeneration metadata | 12 | 12 | Original repair #2588 merged externally as 8705229: 7/7 notebook cells passed with NeqSim 3.16.0, two figures were visually inspected, focused test passed 3/3, and complete Java 8/21 Ubuntu/Windows suites passed. Auto-conversion commit 3f1c465 then replaced curated metadata and added a duplicate H1; #2592 fixed the root cause and merged externally as fd9ee26 after converter tests 3/3, py_compile, real conversion, 7/7 code parity, 3/3 stored outputs, one-H1/no-equation gates, hosted pre-commit, Spotless, documentation/search, CodeQL, agent-reference, and Copilot review passed. A valid post-merge Copilot finding exposed missing Unicode parity in two assertions. #2593 fixed that gap with literal Unicode and ensure_ascii=False expectations and merged externally as d4ee07a. Local tests passed 3/3 and py_compile passed; final-head pre-commit, Spotless, documentation/search, CodeQL, agent-reference, and change-detection passed. Java/Javadoc correctly skipped for the no-Java/XML diff. Copilot reviewed the complete changed file with no comments, suggested changes, or threads. The merge is exactly one file with 3 additions/3 deletions, and master equals the merge commit. No browser-rendered artifact is claimed for the test-only follow-up | merged | #2588, commit 8705229, #2592, commit fd9ee26, #2593, commit d4ee07a |

| D022 | 2026-07-24 | Standards-package landing guide, gas/LNG/oil-quality quick starts, contract boundaries, and executable workflows | 12 | 12 | Merged externally as commit e3f45f5 through #2595. Final head 0abfb7a passed the focused regression 3/3 on Ubuntu and Windows with Java 8/21; complete suites passed with zero failures/errors: 10,875 tests on Ubuntu Java 21 (215 skipped), and 10,673 on Windows Java 21, Ubuntu Java 8, and Windows Java 8 (212 skipped each). Current-source/API audit, seven internal destinations, front matter, Markdown structure, three Java examples, no-equation/no-image/no-external-link scope, two-file diff, pre-commit, Spotless, Javadoc, documentation/search, CodeQL, change detection, and agent-reference checks passed. Eight Copilot findings were assessed (seven applied, one adapted), all threads resolved, and final-head review found nothing new. No rendered-site artifact was available | merged | #2595, commit e3f45f5 |

| D023 | 2026-07-25 | Troubleshooting guide: executable diagnostics, density semantics, process/recycle/phase-envelope APIs, performance guidance, and maintained links | 13 | 13 | Merged as commit c7ea32b through #2597. Final head b626b7d: four independent Python examples pass with NeqSim 3.16.0; five relative destinations resolve; front matter, Markdown, tables, fences, line lengths, and Java 8 syntax checks pass. Focused regression passed 3/3 on Ubuntu/Windows Java 8/21. Complete suites passed with 10,881 tests on Ubuntu Java 21 and 10,679 on the other three matrices, zero failures/errors. Pre-commit, Spotless, Javadoc, documentation-search, CodeQL, change detection, and agent references pass. Copilot reviewed 2/2 files; three findings were applied/adapted and resolved, and final-head review found nothing new. Initial Windows Java 8 failure was an unrelated pre-existing timing benchmark fluctuation; targeted rerun passed. No rendered-site artifact was available | merged | #2597, commit c7ea32b |

| D024 | 2026-07-25 | Notebook index generation, curated engineering/DEXPI discoverability, metadata-driven titles/descriptions, and URL-safe destinations | 5 | 5 | Merged as commit 745b40c through #2598. Exact branch Python regression passed 5/5; 33 notebook blobs and 116 Markdown destinations mapping to 82 repository targets resolved; zero raw-space destinations remained. Hosted build/test/Javadoc, Spotless, pre-commit, documentation search coverage, and CodeQL passed. Copilot reviewed all 3/3 final-head files with no comments, suggested changes, threads, or Copilot-authored commits. Final merge contains only the three frozen files; no equations, notebook cells, images, Java/NeqSim API examples, or production code changed. Browser rendering of nbviewer/Colab was not claimed because the environment rejected the probes before HTTP. | merged | #2598, commit 745b40c |

| D025 | 2026-07-25 | Recent merged code versus documentation: TransientPipe outlet-pressure initialization, executable accumulation/profile APIs, equations, logging, page structure, and internal links | 18 | 18 | Fully merged through #2599 and #2601 as final commit 6ff930b. TransientPipeDocumentationTest passed 2/2 on Ubuntu and Windows with Java 8 and 21. Complete suites passed with zero failures/errors: Ubuntu Java 21 10,884 tests (215 skipped) and Windows Java 21 plus both Java 8 jobs 10,682 tests each (212 skipped). Current-source/API, front matter, Markdown, 16 paired fences, 2 display-math blocks, 4 relative targets plus fragment, pre-commit, Spotless, Javadoc, documentation/search, CodeQL, change detection, and agent-reference checks pass. Copilot findings on #2599 were applied/adapted and resolved; final-head reviews for both PRs found nothing new, #2601 has no review threads, and no Copilot-authored commit exists. Final follow-up diff is exactly one documentation file, 4 additions/6 deletions; master equals 6ff930b. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2599, commit 397214a, #2601, commit 6ff930b |

| D026 | 2026-07-25 | Recent merged energy-stream documentation: page structure, process landing-page navigation, Reference Manual discoverability, and index count | 5 | 5 | Merged externally as commit 3870edc through #2602. The merge is limited to the three frozen documentation files (3 additions/6 deletions). Current-source and focused-test parity covers every shown EnergyStream, EnergyBus, MechanicalShaft, EnergyPortMode, and pump API. Front matter, heading structure, three paired Java fences, corrected README and Reference Manual destinations, hosted build/test/Javadoc, pre-commit, Spotless, documentation search coverage, and CodeQL pass. Copilot reviewed all 3/3 files with no comments or suggested changes; no threads or Copilot-authored commits exist. No equations, images, external links, notebooks, HTML/Markdown interactions, production code, or test changes are in scope. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2602, commit 3870edc |

| D027 | 2026-07-26 | Safety landing page: Jekyll heading structure, internal-link conformance, target resolution, and Markdown table rendering | 19 | 19 | Merged externally as commit de28ff7 through #2604. The merge is exactly one documentation file (17 additions/20 deletions): the duplicate H1 is removed, 17 verified file links now include .md, all 35 link occurrences map to 32 existing destinations, and the detached Barrier Management row is restored to its table. Final-head build/test/Javadoc, pre-commit, Spotless, documentation search coverage, and CodeQL all passed. Copilot approved the complete 1/1 file with zero comments; no threads, suggested changes, or Copilot-authored commits exist. No code fences, equations, images, external links, HTML interactions, Java APIs, tests, notebooks, or production code are in scope. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2604, commit de28ff7 |

| D028 | 2026-07-26 | Thermodynamics landing page: Jekyll title structure, internal-link conformance, and destination resolution | 24 | 24 | Merged externally as commit c0d8d5d through #2605. The merge is exactly one documentation file (23 additions/25 deletions): the duplicate H1 is removed, 23 verified file links now include .md, all 28 link occurrences resolve to 23 files and 5 directory README targets, and zero extensionless file targets remain. Final-head front matter, tree fence, build/test/Javadoc, pre-commit, Spotless, documentation search coverage, and CodeQL pass. Copilot reviewed the final one-file diff with no inline findings or suggested changes; no review threads or Copilot-authored commits exist. No equations, images, HTML interactions, external links, executable examples, tests, notebooks, model implementation, or production code are in scope. No rendered-site artifact was available, so browser inspection is not claimed | merged | #2605, commit c0d8d5d |

| D029 | 2026-07-26 | Process-simulation landing page: Jekyll title structure, internal-link conformance, target resolution, and Markdown table continuity | 23 | 23 | Merged externally as commit 8e97165 through #2606. The one-commit merge changes only docs/simulation/README.md (22 additions/24 deletions): duplicate H1 removed, 22 source links now include .md, all 25 link occurrences resolve to 22 files and 3 directory README targets, zero extensionless file targets remain, and all six tables remain continuous. Front matter, build/test/Javadoc, pre-commit, Spotless, documentation search coverage, and CodeQL passed. Copilot reported zero inline findings or suggested changes; no review threads or Copilot-authored commits exist. jekyll-relative-links converts repository .md targets to published .html/clean URLs; a public .md URL returning 404 is expected.

| D030 | 2026-07-26 | Field-development landing page: metadata completion, Jekyll title structure, internal-link conformance, target resolution, and Markdown continuity | 21 | 21 | Merged as commit 77f4b5b through #2611 after upstream commit 18f2b36 repaired the inherited Energy Networks formatting violations. Final patch is exactly one file (docs/fielddevelopment/README.md, 20 additions/22 deletions): duplicate H1 removed, truncated front-matter description completed, and .md added to 19 file-link occurrences. All 22 link occurrences resolve to 19 unique destinations; front matter, 38 table rows, and 11 balanced code fences pass. PR-head build/test/Javadoc, Spotless workflow, documentation search, and CodeQL passed; the earlier pre-commit failure was limited to upstream Java formatting and its documentation-search hook passed. Final-head Copilot reviewed 1/1 changed files with no new comments; zero review threads or Copilot-authored commits exist. No equations, images, HTML, external links, anchors, changed executable examples, tests, notebooks, production code, or rendered-site inspection were in scope. | merged | #2611, commit 77f4b5b |

| D032 | 2026-07-26 | PVT, flow-assurance, and standards wrapper indexes: search metadata, page title clarity, include continuity, and hosted documentation validation | 1 | 1 | Merged externally as commit 6b34838f through #2624. The merge is exactly one documentation file (docs/pvtsimulation/flowassurance/index.md, 3 additions/2 deletions): the internal token title and tautological description were replaced with reader-facing flow-assurance metadata and topic keywords while the existing README include remained unchanged. Final-head front matter, build/test/Javadoc, pre-commit, Spotless, documentation search coverage, and CodeQL passed. Copilot reviewed the complete 1/1-file diff with no inline comments, suggested changes, or review threads; no Copilot-authored or suggestion commit exists. master contains the verified blob.

The merge commit is exactly the validated two-file repair (docs/tutorials/index.md, 17 additions/17 deletions; docs/cookbook/index.md, 16 additions/16 deletions); the master blobs match the final reviewed head. All 39 internal links resolve to 21 files, all 13 fragments resolve, and the four invalid cookbook anchors are corrected. Front matter, no-duplicate-H1, 46 table rows, balanced fences/math, HTML interaction scan, external NeqSim-Colab/JavaDoc checks, build/test/Javadoc, pre-commit, Spotless, documentation search coverage, and CodeQL passed. Copilot reviewed 2/2 files with no comments, suggested changes, or review threads; no Copilot-authored or suggestion commit exists. No code examples, APIs, tests, notebooks, or production code changed. No rendered-site artifact was available, so browser inspection is not claimed. | merged | #2625, commit a4d2a848 |

| D034 | 2026-07-27 | Public process-to-engineering examples: metadata, Jekyll title structure, source-link conformance, Java evidence, and executable offshore-notebook contract | 9 | 9 | Merged externally as commit 902ddc6 through #2630. The merge contains exactly the verified four-file candidate: one stale exact notebook-cell contract updated from 19 to 26 after the merged HAZOP/SIS expansion, one truncated front-matter description completed, two non-rendering source markers replaced, three duplicate source H1s removed, and two extensionless internal links corrected. Current Java calls match CombinedModelsTest, ProcessModel, and Report. The committed notebook has 47 cells (26 code/21 Markdown), 26/26 executed code cells, 25 output-bearing cells, zero stored errors/stderr, and nine retained images. Final-head build/test/Javadoc, devtools, pre-commit, Spotless, documentation build/search, CodeQL, full notebook execution, executed-output verification, and governed-package artifact upload passed. Copilot reviewed 4/4 files with no comments, suggestions, or threads. No rendered-site artifact was available, so browser inspection is not claimed; the notebook and production engineering code were unchanged. | merged | #2630, commit 902ddc6 |

| D035 | 2026-07-27 | Recent merged code versus documentation: vessel pressure-unit validation and warning semantics | 2 | 2 | Merged externally as commit eaa0ac4 through #2634. The merge is exactly one documentation file (docs/process/equipment/vessel_depressurization.md, 22 additions/5 deletions): duplicate H1 removed; absolute-bara API inputs and internal Pa conversion clarified; exact validate()/validateWithWarnings() error, warning, geometry, and >700 bar behavior documented against focused tests. Front matter, zero duplicate H1s, 70 balanced fence markers, four internal targets, 12 display and 76 inline delimiters, build/test/Javadoc, pre-commit, Spotless, documentation search, and CodeQL passed. Two valid Copilot inline findings and one suppressed observation were applied and validated; final-head review covered 1/1 files with no new comments and no unresolved threads.

The merge contains exactly the frozen guide and focused DEXPI test. Duplicate H1 removed; all 13 internal-link occurrences use existing .md targets and both fragments resolve; the Java 8 example is a complete named program that builds/runs an SRK separator/compressor process, assesses both native DEXPI profiles, and explicitly persists both JSON reports. Dexpi20ProcessModelWriterTest passed 4/4 on Ubuntu and Windows with Java 8 and 21. Each fast suite passed 10,851 tests with zero failures/errors; Ubuntu Java 21 slow shards passed 96, 74, and 44 tests. Pre-commit, Spotless, Javadoc, documentation search, CodeQL, agent-reference, and process-to-engineering workflows passed. Copilot’s one suppressed completeness observation was accepted and validated; the subsequent exact-head review covered 2/2 files with no new comments and no threads remain. No rendered-site artifact was available, so browser inspection is not claimed. | merged | #2651, commit 15c5283 |

Engineering validity

Documentation may explain preliminary NeqSim calculations and engineering workflows, but must not present AI-generated output as accountable design approval. Safety-critical instructions, standards interpretations, and technical limits require traceable sources and appropriate expert review.

    Campaign update: D007 remains blocked after deeper validation

    D007 frozen batch: docs/pvtsimulation/flowassurance/README.md plus FlowAssuranceDocumentationTest.java.

    • Confirmed/fixed: 8 of 8 defects (2 high, 4 medium, 2 low).
    • Current-source audit: all 14 named Java classes confirmed; all 17 internal documentation targets resolve.
    • NeqSim 3.16.0 runtime smoke: MODERATE_PROBLEM, risk index 1.6.
    • Hosted passed on docs: repair flow assurance index #2525: Jekyll build, generated search coverage, search JavaScript, Javadoc, CodeQL, agent-skill references, and scoped Spotless.
    • docs: repair flow assurance index #2525 is still draft, mergeable, exactly two files/two commits ahead of current master, with no review comments or conflicting open documentation PR.
    • The focused D007 JUnit has not executed on the hosted branch; no JUnit pass is claimed.
    • Current master still has the unrelated PhaseAmmoniaEosTest.java:89 checked-exception compile defect and three formatter findings.
    • PR Fix ammonia EOS test compilation #2524 proposes only those compile/formatter repairs. Its pre-commit, Spotless, Javadoc, CodeQL, and agent-skill checks pass. Its Windows matrix then executes 10,526 tests and fails 9 unrelated RCA, field-lifecycle, LNG, and ammonia regressions; Ubuntu is canceled.
    • A local focused-Maven attempt could not complete because this runner lacks a dependency cache and external Maven artifact access; it is not counted as evidence.
    • No external links, equations, or notebooks are in D007. Hosted rendering gates passed, but no browser screenshot is claimed.

    Draft PR: #2525. The branch remains bounded and does not absorb #2524 or the nine unrelated regression fixes. Next action is a focused JUnit and matrix rerun after the upstream compile repair lands. An open PR is not a completed scan.

    PR #2598 merged externally as 745b40cb89426228e3951857696264f7dd772312; I did not merge it.

    • master exactly matches the verified merge commit.
    • The merge contains only docs/convert_notebooks.py, docs/examples/index.md, and docs/test_convert_notebooks.py.
    • Exact branch Python regression passed 5/5; hosted build/test/Javadoc, Spotless, pre-commit, documentation search coverage, and CodeQL passed.
    • All 33 notebook blobs and 116 Markdown destinations mapped to 82 repository targets; zero raw-space destinations remained.
    • master retains all four curated engineering/DEXPI entries, three encoded links for the space-containing notebook, both new regression tests, and the generator helpers.
    • Copilot reviewed all 3/3 final-head files with no comments or suggested changes; no review threads or Copilot-authored commits exist.
    • Browser rendering of nbviewer/Colab is not claimed because the environment rejected probes before HTTP.

    D024 is now recorded as merged in the campaign ledger. Next rotation: D025, recent merged code versus documentation coverage.

    D040 — ISO 6976 regression evidence (merged)

    PR: #2655
    Validated head: 90a52b848a07f99820d82a52b465afe6f306f947
    Merged externally on 2026-07-28 at 20:46:39 UTC as f4b19060b026fd1c660f405964acee986b7e0f40.

    Frozen scope: docs/wiki/gas_quality_standards_from_tests.md in rotation scope 5 (PVT, flow assurance, standards, gas/oil quality). Open-PR overlaps in #2632, #2647, and #2654 were excluded.

    Confirmed defects: stale 44.61 MJ/Nm³ Wobbe value; wrong invalid-reference fallback temperatures; unsafe fallback interpretation; pseudo-component ISO-coverage overclaim; four generated citation artifacts; malformed display math; inaccurate fixture/test attribution; ambiguous pressure and units; source link escaping the Jekyll site; duplicate H1; missing compliance boundary.

    Repair: exact current kJ/Nm³ assertions and conversions, correct 25 °C/15 °C fallback, explicit validator-versus-volume-correction distinction, precise fixture ownership, unsupported-component disclosure, valid Jekyll/GitHub links, standalone $$ math, and measurement/compliance boundaries.

    Validation: the merge contains one changed file only. The merged file and current master both have blob 8b53db5f1399fa3f80c0f4d84c8f500a8cd51155, exactly matching the validated PR artifact. Jekyll build and documentation search coverage passed; pre-commit, Spotless, CodeQL, source-contract/search-JavaScript, and agent-skill checks passed. The unchanged Standard_ISO6976Test blob matched master; exact-branch Java matrices correctly skipped for a documentation-only diff.

    Review disposition: one Copilot thread was accepted, validated, replied to, and resolved; all technically valid suppressed observations were implemented. Final exact-head Copilot review covered 1/1 changed files with no new comments and no unresolved threads.

    No rendered-site screenshot artifact was available, so browser visual inspection is not claimed.

    D040 is completed in the campaign ledger. Next rotation: D041, scope 6.

    D045 frozen scan batch — thermodynamic operations overview

    Rotation scope: 2 — thermodynamics, fluids, phase equilibrium, and physical properties.

    Frozen paths

    • docs/thermo/thermodynamic_operations.md
    • src/test/java/neqsim/DocExamplesCompilationTest.java

    Confirmed pre-edit defects

    • high: nonexistent ThermodynamicOperations.electrolyteFlash() is advertised;
    • high: nonexistent ThermodynamicOperations.calcChemicalEquilibrium() is advertised;
    • high: nonexistent calcSolidFormationTemperature() is advertised;
    • medium: hydrate setup names nonexistent hydrateCheck(true) and treats the double overload as pressure although it is an initial-temperature guess;
    • medium: the Java fragment lacks imports, fluid construction, units, expected output, and a dedicated executable contract;
    • medium: physical-property retrieval omits the required initProperties() boundary and describes getters imprecisely;
    • low: duplicate source H1 conflicts with the Jekyll title, with inconsistent Markdown spacing.

    Validation plan

    1. Verify every retained method, overload, unit, and initialization claim against current source and tests.
    2. Publish a complete Java 8 program; add a focused JUnit regression that executes every shown call and asserts phase fraction, density, enthalpy, and isenthalpic closure.
    3. Run focused JUnit, documentation build/search, Javadoc/build, pre-commit, Spotless, CodeQL, structure/math/fence checks, and all internal-link/anchor checks.
    4. Inspect rendered output if a hosted artifact is available; otherwise record the limitation.
    5. Inspect and disposition every Copilot review thread after the latest push and before readiness.

    Exclusions: #2632's thermo benchmark and reference-index paths; #2676's H2S/reactive-flash/notebook-link/reference-index paths; all other thermo pages and production code.

    No campaign PR is active; this batch will create at most one draft PR linked to #2499.

    Draft PR: #2677
    Validated head: 66691b096c046391c95b555db61020f3df1513b6

    Frozen paths:

    • docs/thermo/thermodynamic_operations.md
    • src/test/java/neqsim/DocExamplesCompilationTest.java

    Confirmed defects repaired:

    • high: three nonexistent ThermodynamicOperations methods were documented as current API;
    • medium: incorrect hydrate call/argument semantics, incomplete Java fragment, missing units and property-initialization boundary;
    • medium: unsafe gas-phase access and brittle bulk/phase property assumptions;
    • low: duplicate H1 and inconsistent Markdown structure.

    Final evidence:

    • API and unit claims checked against current ThermodynamicOperations and SystemInterface source;
    • all nine internal documentation targets resolve;
    • front matter, heading structure, Java fences, documentation build/search, Javadoc, pre-commit, CodeQL, and agent references pass;
    • inspected Spotless artifact contains an empty 0-byte patch;
    • DocExamplesCompilationTest: 44/44 on Java 8 and 21, Ubuntu and Windows;
    • full fast suite on each of those four combinations: 10,884 tests, 0 failures, 0 errors, 212 skipped;
    • all three Java 21 slow shards pass;
    • exact two-file diff, 12 commits ahead and 0 behind current master, no overlap with [AI-Assisted] Add uncertainty-aware thermodynamic benchmark framework #2632 or docs: repair GitHub Pages notebook links #2676;
    • Copilot reviewed both final files with no new findings; all suggestions are dispositioned, accepted changes validated, and no review thread remains open.

    No equations, HTML interactions, images, notebooks, Python, or external links are in scope. No rendered-site artifact was available, so browser visual inspection is not claimed.

    D046 frozen scan batch — generated process-equipment notebook guide

    Rotation scope: 3 — process equipment and process simulation.

    Frozen paths

    • docs/convert_notebooks.py
    • docs/test_convert_notebooks.py
    • docs/examples/process equipmentutl.md
    • docs/examples/index.md

    The notebook itself is evidence only and will not change: docs/examples/process equipmentutl.ipynb.

    Confirmed pre-edit defects

    • medium: the generated Markdown guide contains three raw-space notebook URLs; Markdown/Jekyll can truncate these destinations at the first space;
    • medium: the generated guide and examples index expose the misspelled filename-derived title process equipmentutl instead of the notebook’s reader-facing reservoir-to-market process-equipment title;
    • low: the generated guide prepends an extra filename-derived H1 ahead of the notebook’s real H1.

    Validation plan

    1. Make the converter URL-encode generated notebook links and apply a bounded documentation override for this legacy filename while allowing future notebook metadata to take precedence.
    2. Regenerate only the affected Markdown guide and index row; do not modify or re-execute notebook content.
    3. Extend docs/test_convert_notebooks.py to cover raw-space URL prevention, the legacy override, override precedence, and single-H1 output.
    4. Run the focused Python regression, generator determinism checks for the two affected generated files, front matter/heading/fence/math/HTML scans, internal target checks, and the repository documentation/search validation available in CI.
    5. Inspect every Copilot review thread after the latest push and before readiness.

    Overlap exclusions: #2676 changes many notebook links but not these four files; #2674 changes the distillation guide and solver; #2681 changes TPflash; #2632 changes the thermodynamic benchmark guide and reference index. Those PR paths remain excluded.

    No campaign PR is active. This batch will create at most one draft PR linked to #2499.

    D046 checkpoint — validated, draft PR #2682 remains open

    Frozen scope: docs/convert_notebooks.py, docs/test_convert_notebooks.py, docs/examples/process equipmentutl.md, and docs/examples/index.md; the source notebook was evidence-only and remains unchanged.

    Confirmed and repaired:

    • Medium: three generated notebook destinations used raw spaces; generator now percent-encodes filenames.
    • Medium: the historical misspelled filename leaked into the reader-facing guide and index; a bounded legacy documentation override supplies the notebook’s accurate reservoir-to-market title/description while notebook-owned neqsim_docs metadata remains authoritative.
    • Low: the generated guide duplicated the reader-facing H1; the legacy override now preserves only the notebook-owned H1.
    • Low: the examples-index generator could restore a removed H1; its template is aligned with the committed Jekyll page.

    Validation at exact head e95cb69aedf5a42ba5caedaafae88de5c5f25a21:

    • focused converter tests: 6/6 passed;
    • Python compilation: passed;
    • regeneration from the unchanged 623 kB notebook matched the intended guide, and the single-notebook index matched the intended row;
    • affected front matter, single-H1, raw/encoded URLs, code fences, math delimiters, and HTML detail/summary checks passed;
    • documentation source contracts, Jekyll build, generated search coverage, and search JavaScript syntax passed;
    • pre-commit, Spotless, agent-skill references, and CodeQL passed;
    • Java/XML change detection passed; Java tests, slow tests, and Javadoc were correctly skipped for this documentation/Python-only diff and are not claimed as executed.

    Copilot disposition: one valid Unicode-serialization assertion finding was accepted, fixed, tested, replied to, and resolved. Copilot’s post-fix re-review covered all four files and produced no new comments; no suggestion remains unassessed.

    The successful documentation workflow publishes no rendered-site artifact, so browser visual inspection remains unavailable and is not claimed. No equation, figure, notebook output, Java API, or production behavior changed.

    D046 is validated but not ledger-complete while PR #2682 remains open and unmerged. The PR remains draft, mergeable, current with master, and limited to the frozen four files. D047 remains the next rotation only after D046 merge evidence is recorded.

    The merge contains exactly the four frozen files. All four merge-commit blobs exactly match the validated PR head; current master retains the converter override, encoded guide URLs, corrected generated guide, regression test, and corrected process-equipment index row. The later automatic index regeneration in #2683 changed docs/examples/index.md but preserved the D046 row and encoded destinations.

    Validation evidence remains: converter tests 6/6, Python compilation, deterministic regeneration, front matter/H1/link/fence/math/HTML scans, Jekyll documentation/search, pre-commit, Spotless, agent references, and CodeQL passed. Java tests/slow tests/Javadoc were correctly skipped for the documentation/Python-only diff and are not claimed. Copilot’s sole valid Unicode-serialization finding was implemented, validated, replied to, and resolved; its post-fix four-file review found nothing new.

    The #2499 body ledger now records D040–D046 merged evidence. No rendered-site artifact was available, so browser inspection is not claimed.

    2026-10-24 — D215 merged qualification and D216 frozen contract

    D215 COMPLETE. Draft PR #4539 merged externally from preserved final head 150614f9421d37f31dba5e3b311e58faf5246cfa as commit 1fa78771f0990a0b87411e257d013aa89776473c. Current master is 63b7b36c45a410cc34dfd86ccc607a777cc0ca54. All six final-head workflow groups pass, and the core build/test/Javadoc run passes 19/19 jobs, including Java 8/21 on Ubuntu and Windows, all eight Java 21 slow shards plus aggregate, model specifications, benchmark, Javadocs, and agent-reference checks. The three frozen blobs are byte-identical at the qualified head and current master:

    • docs/standards/astm_d6377_rvp.md: a28b1ba510d502e04ec84699cfa2216013dedab0
    • docs/test_astm_d6377_documentation.py: 76f59c022b018fda5b34db8b4625b751a8c0bf5b
    • src/test/java/neqsim/standards/oilquality/AstmD6377DocumentationTest.java: c0b52fc66448d6e13e0f9323b27d7e67d67015fb

    No submitted review, conversation comment, or inline review thread existed. This records external integration without inferring retrospective approval or a campaign merge action.

    D216 IN PROGRESS — rotation scope 1, landing pages and internal navigation. Exact base/master: 63b7b36c45a410cc34dfd86ccc607a777cc0ca54.

    The bounded audit inspected the complete standards landing page, its current destinations, the reference-manual standards table, and both existing standards navigation contracts. docs/standards/README.md contains nine repository-relative guide destinations without the required .md source suffix: ISO 6976 (including its anchored provenance link), ISO 6578, dew point, ISO 15403, EN 16726/16723, ASTM D6377, oil-quality methods, and sales contracts. All destinations currently resolve only because the broad link checker tries extensionless Jekyll candidates; test_oil_quality_standards_documentation.py explicitly preserves the stale extensionless oil-quality link, and the scope-wide contract does not reject extensionless source links.

    Frozen paths:

    • docs/standards/README.md
    • docs/test_pvt_flow_assurance_standards_documentation.py
    • docs/test_oil_quality_standards_documentation.py

    Acceptance: add the explicit .md suffix to all nine relative guide destinations while preserving the existing ISO 6976 anchor; require every repository-relative link in the standards landing page to name a Markdown source, resolve to a file, and resolve any fragment to a current heading; update the oil-quality discoverability assertion to the explicit source route. Preserve all page prose, tables, Java examples, expected values, equations, external links, and production behavior.

    Ownership/capacity: the frozen paths are disjoint from open autonomous work #4540 and #4541. D216 is the sole active #2499 lane. Positively identified autonomous implementation occupancy is 2/10; this navigation/test-only batch does not increase that count. Ten remains the target and absolute global ceiling.

    Stop boundary: no Java example, standard calculation, source/JUnit, model, equation, expected value, external URL, index topology, notebook, generated inventory, Huldra, release, merge, rebase, synchronization, or ready-state change. Publish draft-only from an isolated exact-base branch; one attributable repair is available if hosted validation identifies a branch-owned defect.

    Draft #4545 is open at exact head 8ab55a57e04a698dbd1d8bae9515257c68cf797a, based on 63b7b36c45a410cc34dfd86ccc607a777cc0ca54. It changes exactly the three frozen paths and is the sole active #2499 lane.

    Static exact-head validation passed: all nine landing-page destinations now use explicit .md source routes; all eight distinct targets exist; the retained ISO 6976 fragment resolves to the current Step 5 - Relative Density heading; and the standards landing-page body differs from the exact base only by those nine suffix additions. The focused contract now requires explicit Markdown sources, target existence, and fragment resolution; the oil-quality discoverability assertion names the explicit source route.

    Hosted workflow groups for documentation search, pre-commit, Spotless, CodeQL, and core build/test/Javadoc are active. No submitted review or inline review thread exists. Autonomous implementation occupancy remains 2/10; #4545 is documentation/test-only and does not increase that count.

    2026-10-24 — D216 authoritative route-contract repair

    The first hosted pre-commit run on 8ab55a57e04a698dbd1d8bae9515257c68cf797a passed the core change-detection and Spotless workflows but failed documentation search because all nine proposed .md suffixes violate the repository's required extensionless published-URL contract.

    D216's single attributable repair restored docs/standards/README.md and docs/test_oil_quality_standards_documentation.py byte-for-byte to exact base 63b7b36c45a410cc34dfd86ccc607a777cc0ca54, then narrowed the focused regression to the authoritative behavior. Draft #4545 is mergeable and unchanged as draft at new exact head edb53c10a16d6eba13a7f035d8f86eaf221b9f34. Its final diff is one frozen test file with 42 additions: require all nine internal landing routes to remain extensionless, resolve each to a source candidate, and resolve the retained ISO 6976 fragment to a current heading.

    Repaired-head documentation search, pre-commit, Spotless, CodeQL, and core build/test/Javadoc workflows are active. No additional repair, retry, rebase, synchronization, readiness transition, merge, peer-head, Huldra, release, or scope expansion is authorized.

    D217 frozen contract — Huron–Vidal/NRTL executable guide

    Rotation/dependency: scope 2 (thermodynamics / fluids / phase equilibrium / physical properties), following D216 scope 1. Current autonomous implementation occupancy is 4/10 (#4559, #4541, #4568, #4572). There is no open #2499 PR and no overlap with their changed paths.

    Exact base: 8f471dd7b28d0f151d203d6f880a8cb95cc7753a

    2. docs/test_mixing_rules_documentation.py
    3. src/test/java/neqsim/thermo/HuronVidalMixingRulesDocumentationTest.java (new)

    Acceptance

    • Replace the four incomplete Huron–Vidal fragments in section 4 with one complete Java 8 program using Log4j2.
    • The program must select setMixingRule("HV", "NRTL"), execute a TP flash, obtain HVMixingRulesInterface, and verify finite Dij, DijT, alpha, tau = Dij / T + DijT, finite phase results, and material balance.
    • Explain type 3 versus type 4, the source-supported GE selectors (NRTL, NRTL_HV, UNIFAC, UNIFAC_PSRK, UNIFAC_UMRPRU), and the explicit UNIQUAC rejection.
    • State parameter units and the exact source semantics: Dij is in kelvin, DijT is dimensionless, and D_eff(T)/T = Dij/T + DijT.
    • Extend the Python source contract for enum mappings, selector branches, formula, maintained fence markers, links, and forbidden console output.
    • Add a Java documentation test that extracts the exact marked program, compiles it with Java 8 source/target, enables assertions, and executes it.
    • Fast validation must include the focused Python contract, focused Maven documentation test, Spotless, documentation search, diff/whitespace checks, and unchanged-worktree verification before draft publication.

    Explicit exclusions: no production Java changes; no mixing algorithm or coefficient changes; no database changes; no edits outside section 4 except contract plumbing; no indexes, notebooks, Huldra files, release work, or unrelated cleanup.

    D217 published — draft PR #4574

    • Draft: docs(thermo): execute Huron-Vidal NRTL guide #4574
    • Exact head: 033b7cb54fa664d1fd0b1903d96a36506540f919
    • Exact base: 8f471dd7b28d0f151d203d6f880a8cb95cc7753a
    • Frozen paths preserved: the mixing-rule guide, its Python source contract, and one new Java documentation-execution test.
    • Remote compare/read-back confirms no production Java changes and no overlap with the four pre-existing active implementation PRs.
    • The pre-publication read-back caught double-escaped Python regexes; the single allowed branch-attributable repair wave corrected those literals and normalized the Java harness before the draft was opened.
    • Validation state: PENDING CI. No success is claimed until exact-head workflows complete.
    • Portfolio state after publication: D217 remains documentation/test-only and does not add an autonomous implementation capability; positively identified implementation occupancy remains 4/10.

    D217 exact-head validation failure — repair deferred by cadence

    Draft #4574 remains open, draft, and mergeable on exact head c139057c685493374c05418b004787bee45563d6. No head replacement, rebase, closure, or abandonment was performed.

    Fast-gate evidence:

    • PASS: Spotless patch generation.
    • PASS: Engineering Capability Coverage.
    • FAIL: Documentation Search Coverage, specifically the documentation-contract suite. The search-source audit itself passed (803 Markdown pages and one standalone HTML page).
    • FAIL: pre-commit, specifically the Spotless Java hook. Its documentation-search hook passed.
    • Build/Test/Javadoc and CodeQL were still running when this checkpoint was recorded.

    Branch-attributable next repair is fully diagnosed:

    1. change the example import from neqsim.thermo.ThermodynamicOperations to neqsim.thermodynamicoperations.ThermodynamicOperations;
    2. contract the actual equalsIgnoreCase("UNIQUAC") rejection branch;
    3. match the source's parenthesized Dji / (temperature) + DjiT and corresponding Dij expression;
    4. apply the exact Java layout printed by Spotless.

    This run already consumed the single branch-attributable repair wave while correcting the pre-publication double-escaped regex contract. Per cadence, no second code repair is being stacked into this run. The next invocation should repair this same exact head/branch before considering any new batch. Positively identified autonomous implementation occupancy remains 4/10; D217 is documentation/test-only.

    D217 exact-head qualification — review pending

    Draft PR #4574 is now fully qualified on exact head b3a1f58f293eed2dccb099cbbbbfce17c687e800.

    • Frozen scope remains exactly three paths:
      • docs/thermo/mixing_rules_guide.md
      • docs/test_mixing_rules_documentation.py
      • src/test/java/neqsim/thermo/HuronVidalMixingRulesDocumentationTest.java
    • The previously ledgered repair was applied as a leased fast-forward on the existing branch; no rebase, replacement, closure, readiness transition, or force update occurred.
    • All six exact-head workflow groups pass:
      • Build/Test/Javadoc — 19/19 jobs passed across Java 8/21, Linux/Windows, fast tests, all eight slow-test shards, model specifications, Javadoc, and agentic benchmark accuracy.
      • Documentation Search Coverage — passed.
      • Spotless — passed.
      • Pre-commit — passed.
      • CodeQL — passed.
      • Engineering Capability Coverage — passed.
    • The exact published example is compiled with Java 8 source/target and executed with assertions; the focused 34-test HV/mixing-rule suite and all 540 documentation contracts also passed locally as recorded in the PR.
    • Reviews, conversation comments, and unresolved review threads: none.
    • Current status: EXACT-HEAD CI QUALIFIED — REVIEW PENDING; KEEP DRAFT.

    Current master is four commits ahead, but GitHub reports the PR mergeable and the compare remains limited to the frozen three paths. Exact-head continuity is preserved; no rebase is justified merely to erase the behind count.

    Positively identified autonomous implementation occupancy is 3/10 (#4559, #4577, #4580). D217 remains documentation/test-only and is the sole active #2499 PR.

    2026-10-25 — D217 merged qualification and D218 frozen contract

    D217 COMPLETE. Draft PR #4574 merged externally from preserved final head b3a1f58f293eed2dccb099cbbbbfce17c687e800 as commit f40bb5642345a2222bb39d556a44138352af5867. All six final-head workflow groups passed, including 19/19 Build/Test/Javadoc jobs. Reviews, conversation comments, and unresolved review threads remained empty.

    The three frozen blobs are byte-identical at the qualified head and current master:

    • docs/thermo/mixing_rules_guide.md: 34ec4dd31a4dc6a992c0b49658af5eb0da0e7726
    • docs/test_mixing_rules_documentation.py: 4d8b255638b0b565241e3661c84c3686fd51b900
    • src/test/java/neqsim/thermo/HuronVidalMixingRulesDocumentationTest.java: 984f4d89133e3ebe2b8a819c7e9855be074e89b8

    This records external integration without inferring retrospective approval or a campaign merge action.

    D218 IN PROGRESS — rotation scope 3, process equipment and process simulation. Exact base/master: fc7c8c40924a6c7bf385735fabc5712a6f1e8a8d.

    A bounded audit of the plug-flow-reactor guide found eight forbidden System.out calls in the three complete result-bearing worked examples. The examples are based on current PlugFlowReactorTest fixtures but are not extracted and compiled from the published fences, so logging edits or API drift can bypass documentation validation.

    Frozen paths

    1. docs/process/equipment/plug_flow_reactor.md
    2. src/test/java/neqsim/process/equipment/reactor/PlugFlowReactorDocumentationTest.java (new)

    Acceptance

    • Replace all eight console-output calls in worked examples 1–3 with parameterized Log4j2.
    • Add finite and physical assertions for conversion, outlet temperature, pressure drop, heat duty, and axial-profile shape where applicable.
    • Mark the three exact Java fences and add a focused JUnit harness that extracts each published snippet, wraps it with only verified current imports, compiles it with Java 8 source/target settings, enables assertions, and executes it.
    • Require exactly three marked examples and reject System.out / System.err in each extracted source.
    • Preserve the illustrative reaction assumptions and explicitly avoid claiming kinetic, catalyst, scale-up, or experimental qualification.

    Ownership/capacity: no open #2499 PR exists. The frozen paths do not overlap open autonomous implementation PRs #4577, #4580, or #4585. Positively identified autonomous implementation occupancy is 3/10; this documentation/test-only batch does not increase that count. Ten remains the target and absolute global ceiling.

    Stop boundary: no production Java, kinetics, coefficients, numerical defaults, equations, examples 4–6, Python/notebook, index topology, Huldra, release, merge, rebase, synchronization, peer-head, or ready-state change. Publish draft-only from an isolated exact-base branch; one branch-attributable repair is available if hosted validation identifies a defect.

    2026-10-25 — D218 draft published from exact base

    Draft #4588 is open, draft, and mergeable at exact head 2cf1f3ba110e1ca2ed7e61f9852cb4d78787ed97, based on fc7c8c40924a6c7bf385735fabc5712a6f1e8a8d. It changes exactly the two frozen paths and is the sole active #2499 lane.

    Connector read-back confirms the guide contains three ordered marked PFR worked examples, zero forbidden System.out / System.err calls, three parameterized Log4j2 logger declarations, and finite/physical assertions. The new Java harness extracts the exact three snippets, rejects console output, wraps them only with verified current imports, compiles with Java 8 source/target settings, enables assertions, and executes every generated program.

    All seven hosted workflow groups are active: Build/Test/Javadoc, Documentation Search Coverage, Spotless, pre-commit, CodeQL, Engineering Capability Coverage, and Production Optimization Documentation. No review or unresolved thread exists.

    VALIDATION PENDING EXACT-HEAD HOSTED CI — KEEP DRAFT. No local Maven, Spotless, pre-commit, Jekyll, Javadoc, or Java execution is claimed. One branch-attributable repair remains available if hosted evidence identifies a defect. No rebase, synchronization, readiness, merge, peer-head, Huldra, release, or scope expansion is authorized.

    Positively identified autonomous implementation occupancy remains 3/10 (#4577, #4580, #4585); D218 is documentation/test-only and does not increase that count.

    2026-10-25 — D218 single repair applied

    Initial exact head 2cf1f3ba110e1ca2ed7e61f9852cb4d78787ed97 exposed one branch-attributable defect: [Core] Pre-commit Checks run 40195650203 failed only because the new documentation harness did not match Spotless formatting. Documentation search passed in that job.

    The campaign's single permitted repair applied the exact patch emitted by successful Spotless Format Patch run 40195650229. The formatted harness blob is 67da1e722d19bc6bda9b12a5f21a11b902b8e0bf; no behavior or frozen scope changed. Draft #4588 now remains open, draft, and mergeable at preserved successor head a999966a0385ff97aba7c32ebaecfcc940669f9f, three commits ahead of and zero behind exact base fc7c8c40924a6c7bf385735fabc5712a6f1e8a8d, with exactly the same two frozen paths.

    Exact-head fast revalidation has passed Engineering Capability Coverage, Spotless Format Patch (empty formatting delta), and the full pre-commit checks. CodeQL, Documentation Search Coverage, Production Optimization Documentation, and Build/Test/Javadoc remain queued or in progress.

    FULL REVALIDATION PENDING EXACT-HEAD HOSTED CI — KEEP DRAFT. The repair allowance is now consumed. No local Maven, Spotless, pre-commit, Jekyll, Javadoc, or Java execution is claimed. No rebase, synchronization, readiness, merge, peer-head, Huldra, release, or scope expansion is authorized.

    Positively identified autonomous implementation occupancy remains 3/10 (#4577, #4580, #4585); D218 remains documentation/test-only.

All seven final-head workflow groups passed, including 19/19 Build/Test/Javadoc jobs and 26/26 jobs across the full hosted set.

    D219 IN PROGRESS — rotation scope 4, engineering design and safety. Exact base/master: 9f1c667aeed816a3fa0ce78f5981fcbfc3eb4e3e.

    A bounded alarm-documentation audit found 23 Java fences that are fragmented rather than exact executable programs, six forbidden System.out calls, duplicate page-title headings, a nonexistent ProcessLogicWithAlarmsExample.java reference, and unsupported claims of ISA-18.2 alignment, production readiness, SIL-1/SIL-2 realization, and direct alarm-to-SIS/HIPPS/ESD qualification. The linked test-source demonstration also activates HIPPS logic independently from each transmitter while the page describes 2oo3 voting. These defects can mislead readers about the separation between operator alarms and independently engineered protective functions.

    Frozen paths

    1. docs/safety/alarm_system_guide.md
    2. docs/safety/alarm_triggered_logic_example.md
    3. src/test/java/neqsim/process/alarm/AlarmSystemDocumentationTest.java (new)

    Acceptance

    • Replace the fragmented alarm snippets with one complete Java 8 example using current AlarmConfig, PressureTransmitter, ProcessAlarmManager, alarm event/history/snapshot APIs, finite assertions, and parameterized Log4j2.
    • Mark the exact published Java fence and add a focused JUnit harness that extracts, wraps, compiles, enables assertions, and executes it; require exactly one marked example and reject System.out / System.err.
    • Remove duplicate H1 headings and the nonexistent example reference.
    • Recast the integration page as an implementation-reading guide for the existing test-source demonstration. Remove fabricated output, automatic-action recipes, and unsupported ISA/SIL/production-readiness claims.
    • State explicitly that alarm configuration and NeqSim action handlers are simulation mechanisms, not evidence of standards compliance, voting independence, safety integrity, response-time qualification, or authority approval.
    • Preserve discoverability and current API links without adding new pages or index churn.

    Ownership/capacity: no open #2499 PR exists. The frozen paths do not overlap open PRs #4577, #4594, #4600, #4601, or #4602. Positively identified autonomous implementation occupancy is 3/10 (#4577, #4600, #4602); D219 is documentation/test-only and does not increase that count.

    Stop boundary: no production Java, alarm-state behavior, setpoints, SIS/HIPPS/ESD logic, standards implementation, engineering coverage, notebooks, index topology, Huldra, release, merge, rebase, synchronization, peer-head, or ready-state change. Publish draft-only from an isolated exact-base branch; one branch-attributable repair is available if hosted validation identifies a defect.

    Confirmed defects in the bounded dynamic-Python subsection:

    • the example imports the nonexistent case-sensitive gateway name jNeqSim instead of jneqsim
    • it depends on an undefined inlet_stream, so it is not a complete runnable example
    • it imports unused raw JClass wrappers for three types and bypasses the documented gateway for others
    • its periodic output condition compares accumulated floating-point time for exact equality, so intended reports can be skipped
    • current contracts execute Java examples but do not protect this Python block's syntax, gateway, definition order, or dynamic API sequence

    Acceptance contract:

    • make the Python example standalone with from neqsim import jneqsim, an explicit SRK fluid, inlet stream, units, mixing rule, and initial run
    • access compressor, driver, enum, and anti-surge APIs through the supported gateway; remove unused JClass imports
    • use an integer step loop for deterministic reporting and retain inline operating-state/history results
    • add a Python AST/source contract for syntax, gateway spelling, definition order, deterministic loop, and forbidden legacy/raw imports
    • extend the existing compressor documentation JUnit test to extract the exact Python fence and execute the same current Java APIs with finite/bounded state and history assertions
    • change no production code, compressor physics, defaults, notebooks, images, external links, Huldra, catalogs, or unrelated guide sections

Reviews, conversation comments, and review threads remained empty.

    Both frozen blobs are byte-identical at final head, merge commit, and current master@7197827e8e9fd88a47f26305db8963c9c4e7328e: guide = d7a2003f6d1fd63ca8e74b2edf737794b4fe7916; exact-source test = ebf3a1c76bf89d33cc3ad2342bf6bfe8f039b6aa.

    Ownership and capacity: D227 is merged and its final head remains preserved. The #2499 one-active-PR gate is clear. Four other open autonomous implementation PRs are positively identified, so implementation occupancy is 4/10. Next rotation: D228, scope 5 — PVT, flow assurance, standards, and gas/oil quality.

    D228 — oil-quality quick-start exact-source contract

    • state: complete — PR docs: execute oil quality quick start #4703 merged externally
    • roadmap rotation: scope 5 — PVT, flow assurance, standards, and gas/oil quality

    • exact frozen paths:
      • docs/standards/oil_quality_standards.md
      • src/test/java/neqsim/documentation/OilQualityQuickStartDocumentationTest.java

    Completion result: the oil-quality quick start is complete Java 8 source using explicit ASTM D4052/D86 imports, no console output, finite API-gravity validation, and a finite ordered distillation-curve contract. The uniquely marked fence is extracted verbatim, compiled with Java 8 source/target, and executed. The final repair preserves the existing documentation-contract names apiStd and distStd.

    Local validation recorded on the final head: 541 documentation tests and 55 focused/adjacent Java tests passed; direct Spotless, documentation search, pre-commit, pre-push, and diff gates passed. All six final-head workflow groups passed; Build/Test/Javadoc passed 19/19 jobs, including Java 8 and Java 21 on Ubuntu and Windows, all slow-test shards and aggregate, Javadocs, model specifications, agent-skill references, and the agentic benchmark. Reviews, conversation comments, and review threads remained empty.

    Both frozen blobs are byte-identical at final head, merge commit, and current master@e7d0fcab6c9805b5267cfce12268ec5e07c5c930: guide = 12214b7f238a807d32fe7a92eee31690937b55c8; exact-source test = a168840072e4d30953aea4a8a89db469f310557a.

    Ownership and capacity: D228 is merged and its final head remains preserved. The #2499 one-active-PR gate is clear. Five open autonomous implementation PRs are positively identified, so implementation occupancy is 5/10. Next rotation: D229, scope 6 — tutorials, cookbook, troubleshooting, and examples.

    D229 — render task contribution follow-up

    • state: active — draft PR docs: render task contribution follow-up #4709
    • roadmap rotation: scope 6 — tutorials, cookbook, troubleshooting, and examples
    • frozen branch point: e7d0fcab6c9805b5267cfce12268ec5e07c5c930

    • exact frozen paths:
      • docs/tutorials/solve-engineering-task.md
      • docs/test_tutorial_cookbook_examples_documentation.py

    Defect and acceptance: the “Full: Create a Pull Request” PowerShell fence swallowed the tutorial's entire Further Reading section. D229 keeps the gh pr create command inside the contribution fence, restores the heading and agentic-workflow links to rendered Markdown, and adds a focused contract against another fence-boundary regression.

    Publication validation on the exact head: the branch is 2 commits ahead and 0 behind its frozen base; the comparison contains exactly the two frozen modified paths. The focused contract logic confirms that the command remains in the contribution section but not rendered prose, while Further Reading and its workflow link remain rendered. All five exact-head workflow groups passed: Spotless Format Patch, Documentation Search Coverage, Build/Test/Javadoc routing, Pre-commit Checks, and CodeQL Security Analysis. The documentation workflow passed contract tests, documentation build, generated-search coverage, and search-JavaScript syntax checks. Reviews, conversation comments, and review threads are empty.

    Ownership and capacity: no other open #2499 PR existed immediately before publication, and the two frozen paths do not overlap the changed files of the five open autonomous implementation PRs. Implementation occupancy remains 5/10; the #2499 one-active-PR gate is now occupied by draft #4709. Preserve exact head 356b54064bc8d56f71951ce6696b7d2cae0b0758; do not rebase, replace, close, abandon, or mark ready. Next rotation remains blocked until D229 completes.

      • docs/test_python_quickstart_units.py
      • src/test/java/neqsim/process/equipment/compressor/CompressorFixedSpeedControlTest.java — formatter-only repair

    Completion result: the Python quickstart now states Python 3.10+, Java 17+ for pip, Conda with OpenJDK included, 64-bit architecture compatibility, and the authoritative installation source. The third final path is the exact Spotless-only compressor-test repair inherited from the base and changes no assertion or behavior.

    All seven final-head workflow groups passed; Build/Test/Javadoc passed 19/19 jobs, including Java 8 and Java 21 on Ubuntu/Windows, all slow-test shards and their aggregate, Javadocs, model specifications, the agentic benchmark, CodeQL, Spotless, pre-commit, documentation search, engineering capability coverage, and production-optimization documentation. Reviews, conversation comments, and inline review threads remained empty.

    All three final blobs are byte-identical at the final head, merge commit, and current master@c02e7cf52cf7ac4d77f688f82be2d455afa088aa: quickstart = 31573b438eb8c76bd5ca0f0c7fbb2fe339446ee0; regression = 37f97d9ff20f3b0312588951fb07cf4b87ba8d67; formatter repair = 0e050758add3980397c9dfa45642e657b28f20e9.

    D231 — analyser sample-system executable guidance

    Completion result: the public AnalyserSampleSystem now has bounded user guidance for condensation margins, transport lag, film persistence, units, assumptions, and installed-system limits. Its uniquely marked complete Java program is extracted literally, compiled with Java 8 source/target, and executed with engineering assertions.

    All six final-head workflow groups passed; Build/Test/Javadoc passed 19/19 jobs, including Java 8 and Java 21 on Ubuntu and Windows, all slow shards and aggregate, Javadocs, model specifications, agent-skill references, and the agentic benchmark. Reviews, conversation comments, and review threads remained empty. Both frozen blobs are byte-identical at the final head, merge commit, and current master@5078e1e1a0ff6aa979913de166212d496496370a: guide = fb7c1566271f11c2d695d4a7731e23c16b9e1ed9; executable contract = a0be9d7889c9ad2ba95df685647929d93add3c52. The sole branch-attributable repair was the exact hosted Spotless artifact; no local gate pass is claimed.

    D232 — standards navigation from the documentation landing page

    • state: complete — PR [AI-Assisted] docs: expose standards guides from landing page #4727 merged externally
    • roadmap rotation: scope 1 — landing pages, navigation, indexes, and internal links
    • exact frozen base: 5078e1e1a0ff6aa979913de166212d496496370a

    • exact frozen paths:
      • docs/index.md
      • docs/test_top_level_navigation.py

    Completion result: the main landing page now has one bounded Standards & Measurement card linking the standards overview, the dew-point/analyser guide, and EN gas-quality screening. The top-level navigation contract requires each route exactly once, resolves each route to its Markdown source, and preserves sampling-system and interpretation-limit wording.

    All five final-head workflow groups passed: documentation search coverage, Spotless, pre-commit, Build/Test/Javadoc routing, and CodeQL. The documentation workflow passed search-source contracts, all documentation contracts, the Jekyll build, generated-search coverage, and search-JavaScript syntax. Reviews, conversation comments, and review threads remained empty. No branch repair was required and no unexecuted local gate is claimed.

    Both frozen blobs are byte-identical at final head, merge commit, and current master@1929a43a8f431f81161732b2c9a1deb5f753ac42: landing page = d7fb703f40c53cefa2be3af141aa40133e67aa56; navigation contract = e1d3499d5cb68a786eb887922585340504e15f95.

    • exact frozen paths:
      • docs/physical_properties/diffusivity_models.md
      • src/test/java/neqsim/physicalproperties/DiffusivityGuideDocumentationTest.java

    Completion result: the diffusivity guide's complete methane/nitrogen Fuller program is uniquely marked, compiled from the literal published source with Java 8 source/target, and executed with a bounded ambient-pressure gas sanity contract. The sole branch-attributable repair was the formatter-only Spotless artifact; the final head is preserved without rebase or replacement.

    Engineering Capability Coverage, Spotless, pre-commit, CodeQL, and Documentation Search passed. Build/Test/Javadoc recorded the unrelated Java 8 failure CompressorChartPolytropicMethodTest.smallWetGasPowerRetainsFinitePressureRise; ownership was explicitly assigned to #4735 rather than duplicated in D233. PR #4733 was nevertheless merged externally. Both frozen blobs are byte-identical at the final head, merge commit, and current master@9975919e7908fe4ef34bbfeca37055d8883116fa: guide = 198f462e4dfaf9e6d81b5532693e8c918695a47b; exact-source test = d34329898f9ae88bc3139b7d9fc3b16a29db84ea. Huldra is unaffected.

    • exact frozen paths:
      • docs/process/README.md
      • src/test/java/neqsim/process/processmodel/ProcessSystemDocumentationTest.java

    Completion result: the complete valve-and-separator Java 8 quick start is uniquely marked, extracted from the literal guide source, compiled with Java 8 source/target, and executed. The stream-topology ownership contract remains. The sole campaign repair was the formatter-only hosted Spotless artifact at ac602f3a.

    Six workflow groups passed. Build/Test/Javadoc passed model specifications, Java 21 Javadocs, agent-skill references, the agentic benchmark, all eight slow shards, and the aggregate slow gate. Both Java 21 fast suites executed ProcessSystemDocumentationTest 2/2 successfully, then failed only in the unrelated CompressorChartPolytropicMethodTest.smallWetGasPowerRetainsFinitePressureRise; that baseline was owned and repaired by #4739 rather than duplicated here. Java 8 full suites were consequently skipped. PR #4737 was nevertheless merged externally.

    An external actor merged then-current master into the branch after the preserved contribution head. That integration changed only four compressor/coverage paths already present on the base at merge time; it did not alter either frozen D234 blob. The guide blob c7ac9810135e280d762135dd3639cd9fffd3b1d8 and JUnit blob 062beddae9ed48711f1382e45bcc380f939662d4 are byte-identical at the preserved contribution head, external branch-integration head, merge commit, and current master. The campaign records that external history without rewriting it. Huldra is unaffected.

    D235 — process-safety overview exact-source execution

    • state: complete — PR #4745 merged externally
    • roadmap rotation: scope 4 — engineering design, safety, DEXPI, and field development
    • exact frozen base: a01d663990a8f43de366a8c02f1ea6280b61c143
    • initial publication head: beb6f8e6d108efdb606aa5e9a96108363a8a8d5e
    • final exact head: a6fd504f9545cc45c7dc58c5ee8e801d7aa38d6a
    • exact frozen paths:
      • docs/process/safety/README.md
      • src/test/java/neqsim/process/safety/ProcessSafetyOverviewDocumentationTest.java

    Defect and acceptance: the complete pressure-protection and ESD Java 8 quick start and its JUnit coverage duplicated the same program, so either copy could drift while the test stayed green. D235 uniquely marks the literal fence, extracts it from the guide, compiles it with Java 8 source/target, executes its main method, rejects console output, and retains the separate HIPPS signature contract.

    Publication evidence: the branch is exactly three commits ahead and zero behind its frozen base, with exactly the two frozen modified paths. Final blobs are guide = e7545f8260884c0c66f116a4fa360a04a7cd5771; JUnit gate = 36703ef1c262784ae86ae8555a8e1ebcceda4635. Hosted Spotless produced one exact formatter-only artifact; commit a6fd504f applies it byte-for-byte without changing behavior or assertions, consuming the single branch-attributable repair allowance. Four exact-head workflow groups pass: engineering capability coverage, Spotless, pre-commit, and the safety source-term contract. Build/Test/Javadoc passes change detection, agent-skill references, Java 8/21 model specifications, and Java 21 Javadocs; its benchmark and fast/slow suites are active. Documentation search/build, CodeQL, and production-optimization examples/notebooks are also active with no observed failure. No local gate pass is claimed.

    Ownership and capacity: no other open #2499 PR existed immediately before publication. The sole positively identified open autonomous implementation PR is #4744, so implementation occupancy is 1/10; D235 is documentation/test-only and consumes no implementation slot. Its paths do not overlap #4744. The #2499 one-active-PR gate is occupied by draft #4745. Preserve exact head a6fd504f9545cc45c7dc58c5ee8e801d7aa38d6a; do not rebase, replace, close, abandon, merge, synchronize, or mark ready. No production code, DEXPI content, notebooks, Huldra handoff material, or safety physics is changed.

    • frozen paths:
      • docs/process/equipment/compressors.md
      • src/test/java/neqsim/process/equipment/compressor/CompressorGuideDocumentationTest.java

    Defect and acceptance: merged correction #4775 prevents chart-calculated duty from constraining later chart-free solveEfficiency(...) calls. The compressor guide described that workflow but published no complete executable program and had no literal-source execution gate. D239 adds a Java 8 chart-run → chart-disable → speed-solve-disable → efficiency-fit example, checks the fitted temperature and a later chart-free rerun, and compiles/executes the exact marked Markdown fence from JUnit while rejecting console output.

    Repair history: the initial branch received the single hosted Spotless formatting repair. A later run applied the separately authorized narrow Liquid repair recorded in the prior ledger: {% raw %} / {% endraw %} now wrap only the Markdown fence, outside the extracted Java source. The final repair commit changes only docs/process/equipment/compressors.md; the literal Java program and JUnit test blob are unchanged.

    Exact-head evidence: Engineering Capability Coverage, Documentation Search/Jekyll, Production Optimization Documentation, Spotless, pre-commit, and CodeQL all pass. Build/Test/Javadoc has 17 successful jobs: change detection, agent-skill references, Javadocs, Java 8/21 model specifications, Ubuntu/Windows Java 21 fast suites, all eight slow shards and their aggregate, and the agentic benchmark. Java 8 Ubuntu and Windows full suites remain active without observed failures. Reviews and review threads are empty. The PR is mergeable and remains draft; it is NOT YET READY TO MERGE pending both Java 8 suites and independent review.

    Ownership and capacity: one positively identified autonomous implementation PR is active — #4781 — so implementation occupancy is 1/10. Validation-only #4782 and documentation/test-only D239 consume no implementation slots. Neither overlaps a D239 path. Draft #4779 occupies the #2499 one-active-PR gate.

    Preserve exact head 4e0456d6c040fa9806559e4d4183af6ff64584a8; do not rebase, replace, close, abandon, merge, synchronize, or mark ready. After an unchanged merge, rotate to scope 1. No production API, thermodynamic model, numerical behavior, units, notebook, image, or Huldra handoff behavior changes.

D240 adds one direct compressor-guide route to the main Process Simulation card and extends the existing navigation contract to require the route exactly once, resolve it to docs/process/equipment/compressors.md, and preserve the bounded maps/chart-to-efficiency/operational-limits description.

    Connector-side frozen-tree checks confirm exactly two modified paths, one landing route, one Process Simulation card, one registered contract, no overlong updated test lines, and a resolving target source blob. No local checkout, Python execution, full documentation suite, Jekyll render, browser inspection, Spotless, pre-commit, or repository build is claimed. VALIDATION PENDING CI on exact head 04a7c557d55849d2a67c533a3835f50887344ce5.

D241 replaces it with a complete Java 8 PhaseEnvelopeExample, retains the current calcPTphaseEnvelope() and named extrema accessors, validates four returned temperature/pressure values as finite and positive, and compiles/executes the exact marked guide source while rejecting console output.

    Defect and acceptance: the complete pump/API 610 program was unmarked and only logged its calculated values, with no contract compiling or executing the literal Markdown source. D242 uniquely marks the Java 8 fence, adds a silent run() entry point, validates finite positive power/head/NPSH metrics plus a complete assessment/structured response, and adds a literal-source compilation/execution gate that rejects console and Log4j output.

    Connector-side frozen-tree checks confirm exactly two changed paths, one unique marker, one complete public example class, Java 8 source/target flags, reflective execution of run(), no guide console/log output, and the formatter-owned test layout.

    Defect and acceptance: the field-development overview publishes a complete Java 8 screening workflow spanning concept evaluation, option ranking, host holdback, process generation, VFP export, and SURF cost screening, but its regression suite exercised separate hand-written API copies rather than the literal Markdown fence. D243 uniquely marks that fence, extracts and compiles the exact guide source with Java 8 source/target, invokes its main entry point, rejects console output, freezes the current concept-evaluation, holdback, process-linker, VFP-export, and cost-screening calls, and retains all four existing focused tests.

      • docs/process/equipment/heat_exchangers.md
      • src/test/java/neqsim/process/equipment/heatexchanger/HeatExchangerDocumentationTest.java

    Defect and acceptance: the heat-exchanger guide publishes a complete Java quick start, but the existing JUnit regression executed a separate hand-written copy and the published program wrote through System.out.printf. D250 uniquely marks the complete fence, removes console output while retaining executable engineering bounds, extracts and compiles the literal guide source with Java 8 source/target, invokes its main, rejects console output, and retains all three existing heat-exchanger API tests.

    Exact hosted repair: initial head 4a03fce6a4edf346d167838240cd1076c9b330a6 produced Spotless artifact #13286040803 from workflow run 41751060967 (SHA-256 53b0e17bcb636a421169a5cb304648d02bc78e3d2b2c3a89d19a4829a970765d).

    Connector-side frozen-tree checks confirm exactly two changed paths, three append-only commits, zero behind, one unique marker, a complete public class, Java 8 compiler flags, reflective execution, console-output rejection, bounded effectiveness and minimum approach, and retention of all existing tests.

The PR remains draft and mergeable; no repair, rebase, replacement, readiness transition, or merge was performed.

    D253 completion — literal process-comparison example execution

    • merged draft PR: docs: execute literal process-comparison example #4867
    • final preserved head: a7be3a89a42cb1590b22c7263eb871298a36ce44

    • frozen base: b08dc4d57911b884e357b611ed5d9669751d8ec1
    • final scope: exactly two frozen paths and two append-only commits

    All seven exact-head workflow groups passed: Production Optimization Documentation, Documentation Search/Jekyll, Build/Test/Javadoc, Spotless, pre-commit, Engineering Capability Coverage, and CodeQL. Build/Test/Javadoc passed all 19 jobs, including Java 8 and Java 21 on Ubuntu and Windows, all eight slow shards and aggregate, Javadocs, Java 8/21 model specifications, agent-skill references, and the agentic benchmark. Reviews and review threads remained empty. Both frozen files are byte-identical between the preserved head, merge commit, and audited current master. Huldra handoff material is unaffected.

    Ownership and capacity: D253 is merged and the #2499 one-active-PR gate cleared. One positively identified autonomous implementation PR is active — #4868 — so implementation occupancy is 1/10, with ten both the target and absolute global ceiling.

      • src/main/java/neqsim/process/util/optimizer/CompressorOptimizationHelper.java
      • docs/test_optimizer_python_javadocs.py

    Defect and acceptance: two public optimizer Javadocs used the obsolete neqsim.neqsimpython gateway, and the specification-loader Java example used forbidden System.out.println. D254 uses the supported from neqsim import jneqsim import in both Python examples, replaces console output with a finite fail-closed Java check, and adds a contract that extracts and syntax-compiles the exact embedded Python fragments while protecting both optimizer class paths and rejecting legacy imports or Java console calls.

    Connector-side frozen-tree checks confirm exactly three changed paths, four append-only commits, zero behind, two supported imports, no obsolete imports, no Java console calls, and a Python contract using both compile(..., "exec") and ast.parse. Initial hosted status: Skills and Agents Lint, Engineering Capability Coverage, Production Optimization Documentation, Documentation Search/Jekyll, CodeQL, and Spotless are active; pre-commit, Build/Test/Javadoc, and PaperLab Replication are queued. Reviews (0) and review threads (0) are empty. VALIDATION PENDING HOSTED CI on exact head 81be6bffb8ccac06d9558089e946fef2b91c8a81. No local Maven, Python, formatter, or completed hosted-suite pass is claimed.

    Ownership and capacity: #4868 remains the sole positively identified autonomous implementation PR, so occupancy is 1/10. D254 is documentation/test-only and consumes no implementation slot. Its three paths are disjoint from all 17 paths in #4868, and draft #4870 is the sole active #2499 PR.

    D254 generated-inventory exact-head checkpoint

    GitHub Actions appended b90241f091516655411d710593380b4e5a5f2a7f (chore: regenerate engineering coverage inventory) to draft PR #4870. It is one append-only commit ahead of the initial content head, modifies only src/main/resources/neqsim/mcp/engineering-coverage.json, and updates exactly the two optimizer source digests. Independent SHA-256 checks of both current-head Java sources match the generated inventory. Frozen continuity is now five commits, four paths, and zero behind d6dd0cd190ac32f04a08627fafdeff7f745566e5.

    On predecessor content head 81be6bffb8ccac06d9558089e946fef2b91c8a81, eight workflow groups pass: Engineering Capability Coverage, Spotless, Skills/Agents Lint, PaperLab, pre-commit, Documentation Search/Jekyll, Production Optimization Documentation (examples plus all fourteen notebooks), and CodeQL. Spotless artifact #13395881520 has SHA-256 8d12197792bef4d7b7dd2d7761967507b0d1a1c9cba244dca46022ef591fe8e0 and a zero-byte patch. Build/Test/Javadoc has Javadocs, Java 8/21 model specifications, the benchmark, and all eight slow shards passing; only Java 21 Ubuntu/Windows fast tests remain active with no failure signal. The nine current-head workflow registrations concluded action_required with zero jobs, so no current-head hosted-suite pass is claimed.

    Reviews (0) and review threads (0) remain empty. Implementation occupancy remains 1/10 (#4868); D254 remains documentation/test-only and the generated inventory is derivative metadata. Preserve exact head b90241f091516655411d710593380b4e5a5f2a7f; do not rebase, replace, close, abandon, synchronize, merge, or mark ready. No repair was made and the repair allowance remains unused.

    D254 hosted completion and generated-path overlap

    All nine workflow groups on authored-content head 81be6bffb8ccac06d9558089e946fef2b91c8a81 pass. Build/Test/Javadoc passed 19/19 jobs; documentation search/Jekyll, optimization examples and all fourteen notebooks, engineering coverage, Spotless, pre-commit, Skills/Agents Lint, PaperLab, and CodeQL also pass. Spotless remained a zero-byte patch and no branch-attributable repair was used.

    Draft PR #4870 remains open, mergeable, and exact-head preserved at b90241f091516655411d710593380b4e5a5f2a7f: five append-only commits, four paths, zero behind the frozen base. The fifth commit is the GitHub Actions-generated engineering inventory; both changed source digests independently match the current-head Java files. Its nine workflow registrations concluded action_required with zero jobs, so exact-current-head hosted validation remains unavailable and no READY TO MERGE classification is recorded.

    Two implementation capabilities are positively identified — #4868 and #4871 — so occupancy is 2/10 under the ten-capability target and ceiling. D254's three authored paths are disjoint from both implementation PRs. The generated src/main/resources/neqsim/mcp/engineering-coverage.json path is present in all three PRs; this derivative-only overlap is recorded without altering any exact head. Reviews and review threads remain empty. Huldra handoff material is unaffected. The #2499 one-active-PR gate remains occupied by #4870; D255 must not start until it clears.

    D254 rerun evidence: GitHub rejected a connector-safe retry of current-head pre-commit run 41985092806 with HTTP 403 (This workflow run cannot be retried); the action-required run contains zero jobs. No branch, workflow, or exact head was changed.

      • src/test/java/neqsim/thermo/util/readwrite/EclipseE300ImportQuickStartDocumentationTest.java

    Defect and acceptance: the recently updated Eclipse E300 guide contained six non-executable Java fences. Its primary fragment redeclared fluid five times in one scope, later fragments depended on undeclared state, and several used forbidden console output. D255 publishes one complete, uniquely marked Java 8 quick start, retains overload information in API tables and prose, and adds a JUnit contract that extracts the literal fence, requires it to be the guide's only Java fence, compiles it with Java 8 source/target, and invokes its main against fluid_water.E300. The program fails closed for a missing file, verifies automatic multiphase checking for a water-containing import, performs a 100 bara / 90 °C TP flash, initializes properties, and requires a finite positive density without console output.

    Connector-side frozen-tree checks confirm exactly two changed paths, two commits, zero behind, one unique marker, one complete public class, Java 8 compiler arguments, reflective execution, the repository fixture, and forbidden-console checks. No local Maven, formatter, or completed hosted-suite pass is claimed. VALIDATION PENDING HOSTED CI on exact head cf32f641bec2815350249d5645b51d841b08403a.

D255 is documentation/test-only and consumes no implementation slot. Its two paths are disjoint from all paths in those PRs, and draft #4880 is the sole active #2499 PR.

    Preserve exact head cf32f641bec2815350249d5645b51d841b08403a; do not rebase, replace, close, abandon, synchronize, merge, or mark ready. Independent review remains required.

No production API, E300 parser/writer behavior, thermodynamic algorithm, EOS parameter, default, unit convention, notebook, image, external link, Huldra handoff material, generated engineering inventory, release, or peer head is changed.

    D255 exact hosted Spotless repair

    Initial pre-commit failed only because the new JUnit file differed from Google Java Format. The successful Spotless workflow produced artifact #13445351697 (SHA-256 1b0523ee1598aca06e04f876f4debc69951ed320ea08f70df5e51e32dd674b73) containing a 3,515-byte patch for that frozen test path. The artifact patch was applied verbatim as the single allowed branch-attributable repair; resulting test blob 6ef89e2036124e1a93af3fa8a9653be2f94d73be matches the artifact target.

    Current exact head is 44a06ea6f3c4d281c9c5dff1a6f58dc84de6f306: three append-only commits, exactly two frozen paths, and zero behind the exact base at repair time.

D256 links all four destinations to their maintained canonical targets and extends the existing landing-page contract to require each route while rejecting the stale plain-label form.

    Defect and acceptance: the hydrate guide's “Basic Hydrate Check” used SystemInterface without importing it, consisted of top-level statements rather than a compilable class, and used forbidden console output. D257 publishes one complete Java 8 HydrateFormationQuickStart, uses the current SRK-CPA hydrate APIs with explicit multiphase and hydrate checks, and fails closed for non-finite or physically implausible temperature. The regression extracts the uniquely marked literal fence, rejects console output, compiles it with Java 8 source/target, and invokes its main.

The exact frozen-test hunk was applied, and resulting test blob 3f5a01d0dc373b6fed53d4c26326d15e9d1a29c3 matches the artifact target.

    External maintenance appended 4e6c59ecc02982738b0d2aa1a9a228c8a2be247a after the earlier slow shard exposed a checked-exception compiler failure in the literal guide source. The authoritative fourth commit changes only docs/thermo/hydrate_models.md, declares and documents IsNaNException, and preserves the formatted regression blob 3f5a01d0dc373b6fed53d4c26326d15e9d1a29c3. Exact frozen-base continuity is four append-only commits, exactly two paths, zero behind 5fa68e8c67f21ebaaea0d3e7c63be7c0ea58f92a.

    All six current-head workflow groups pass. Build/Test/Javadoc passes 19/19 jobs: Java 8 and Java 21 tests on Ubuntu and Windows, all eight slow shards and aggregate, Java 8/21 model specifications, Java 21 Javadocs, agent-skill references, Java-change detection, and the agentic benchmark. Documentation Search/Jekyll, Spotless, pre-commit, Engineering Capability Coverage, and CodeQL also pass. Current-head Spotless artifact #13488713041 has SHA-256 7e65c183a86551231f08001af78ed49e45e92628e14497f875ed1d94da46c221.

    Reviews (0), conversation comments (0), and review threads (0) remain empty. PR #4887 is therefore READY TO MERGE by the campaign's exact-head gates while remaining draft for independent maintainer disposition. External maintenance exceeded the campaign's already-consumed one-repair allowance; the new head is preserved under exact-head continuity, and no further campaign repair, rebase, replacement, close, abandonment, readiness transition, merge, or peer-head change is permitted.

    Ownership and capacity: #4885, #4888, #4889, and #4890 are four positively identified autonomous implementation capabilities, so occupancy is 4/10 under the ten-capability target and absolute ceiling. Contributor PRs #4872, #4876, and #4877 remain excluded from autonomous occupancy while participating in overlap checks. D257 is documentation/test-only and overlaps none of their authored paths. Draft PR #4887 remains the sole active #2499 delivery, so D258 must not start until this lease clears. Huldra handoff material is unaffected.

    Defect and acceptance: the flare guide's “Basic Usage” was an uncompiled fragment that referenced undeclared inletStream, omitted fluid and process construction, and used console output. D258 publishes one complete Java 8 FlareQuickStart, runs the maintained Flare equipment through a ProcessSystem at explicit 1.2 bara and 1,000 kg/hr conditions, and fails closed for non-finite, non-positive, or implausible heat release and CO2 emissions. The regression extracts the uniquely marked literal fence, rejects console output, compiles it with Java 8 source/target, enables assertions, and invokes main.

    Connector-side frozen-tree checks confirm exactly two changed paths, two commits, zero behind, one unique marker, a complete public class, Java 8 compiler arguments, assertion enablement, reflective execution, and finite bounded validation. No local Maven, Spotless, documentation-search, pre-commit, or pre-push pass is claimed. VALIDATION PENDING HOSTED CI on exact head f6bcc6f45a5241ce2dcc0ee1c96e27434d348876; seven workflow groups are registered.

    Ownership and capacity: #4891 and #4892 are two positively identified autonomous implementation capabilities, so occupancy is 2/10, with ten both the target and absolute global ceiling. Contributor PRs #4872, #4876, and #4877 remain excluded from autonomous occupancy while participating in overlap checks.

      • src/test/java/neqsim/process/safety/LayeredSafetyArchitectureDocumentationTest.java (new)

    Bounded audit evidence: the guide contains seven Java fences, all fragments rather than complete programs; six forbidden System.out calls; a duplicate H1 after Jekyll front matter; undeclared sensors, valves, process values, and action placeholders; and blanket IEC/SIL/fail-safe compliance claims that are not established by software configuration alone. Current source confirms the maintained Detector, VotingLogic, HIPPSLogic, ESDLogic, TripValveAction, ESDValve, and SafetyInstrumentedFunction APIs, but does not turn a configured 2oo3 simulation into certified SIL achievement or an approved plant protection design.

    Acceptance contract: replace the fragmented snippets with one uniquely marked, complete Java 8 program that configures explicit 2oo3 pressure voting, trips a HIPPS isolation valve, escalates a sustained demand into an ESD action sequence, and fails closed on every expected state transition. Use Log4j2 only. Add an exact-source JUnit contract that rejects console output and unsafe blanket certification wording, compiles the literal fence with Java 8 source/target, enables assertions, and executes main. State units, latching/reset and transient-execution ownership, software limitations, and accountable engineering-review boundaries. Preserve current navigation with verified .md targets.

    Stop boundary: no production API, safety algorithm, detector or voting semantics, equipment defaults, SIL/PFD calculation, standards interpretation, DEXPI/PFD artifact, notebook, external data, Huldra handoff material, generated inventory, release, or peer head changes. One branch-attributable repair is available only for a hosted validation defect.

    Ownership and capacity: two positively identified autonomous implementation capabilities are active — #4903 and #4904 — so occupancy is 2/10, with ten both the target and absolute global ceiling. Contributor PRs #4872, #4876, and #4877 remain excluded from autonomous occupancy while participating in path-overlap checks. D259 is documentation/test-only, consumes no implementation slot, and its frozen paths overlap none of those PRs.

    Connector read-back confirms one unique marked Java fence, one complete public Java 8 class, zero guide console writes, explicit 95 bara units, 2oo3 voting, the two-second HIPPS escalation path, an ESD trip action, fail-closed state checks, assertion enablement, and reflective execution. The guide no longer claims that software configuration alone establishes IEC compliance, SIL achievement, or universal fail-safe behavior. The two frozen paths overlap none of autonomous implementation PRs #4903/#4904 or contributor PRs #4872/#4876/#4877.

    D259 external merge reconciliation — final head 0eb0989c9eb9fe8ac48c810f66aaf2fb13c0154c

    PR #4907 merged externally as 622fc29dca784b1dd99348dd143586ca6093d372 after an externally introduced fourth commit merged then-current master into the branch. The campaign did not create, rebase, replace, or rewrite that commit. Its broad inherited changes did not alter D259's two frozen files: guide blob 249c19c39529b944ce36420d52f339c17a618c10 and exact-source test blob 7e31bce06a9bd389138f8b2e1b1aac3894a950e1 are byte-identical at authored head c98822a0bed1b22891ae5d46150ef699c4c4feae, final head, merge commit, and observed master@863f12f4bfb58026e523748aefab14ecaf2288aa. Reviews, comments, and review threads remained empty.

    Seven final-head workflow groups pass: pre-commit, CodeQL, documentation search, production-optimization examples/notebooks, Spotless, Code Health, and Engineering Capability Coverage. Build/Test/Javadoc is 17/19 successful with only Java 8 Ubuntu and Windows still active and no failure conclusion. D259 is merged but final exact-head qualification remains pending those two platform jobs; no readiness or additional repair is claimed.

    Current autonomous implementation occupancy is 1/10 (#4910). Contributor PRs remain excluded from occupancy. D260's next rotation is scope 5. Read-only audit identified a dependency-ready candidate: docs/standards/sales_contracts.md labels a classless fragment as a complete Java example while SalesContractDocumentationTest reimplements rather than extracts the published source. Current API/fixture evidence was verified, and candidate paths do not overlap #4910. D260 is not frozen or started until D259's final-head validation tail completes. Huldra remains unaffected.

    D260 frozen contract — gas sales-contract literal quick start

    • state: frozen, implementation starting
    • roadmap rotation: scope 5 — PVT, flow assurance, standards, and gas/oil quality

    • frozen paths:
      • docs/standards/sales_contracts.md
      • src/test/java/neqsim/standards/salescontract/SalesContractDocumentationTest.java

    Bounded audit evidence: the guide labels a classless sequence of imports and statements as a “Complete Java example.” The existing JUnit test independently reimplements that scenario, so the published fence can drift or stop compiling while the test remains green. Current source and the bundled central / Brazil fixture confirm the maintained BaseContract, SystemGERGwaterEos, result-table, and 8-row contracts used by this repair.

    Acceptance contract: publish one uniquely marked, complete Java 8 GasSalesContractQuickStart with imports, class and method documentation, an explicit gas fixture, database-backed contract execution, finite row-by-row limit parsing, and fail-closed checks for the 8-row fixture and CO2 evidence. Introduce no console calls. Extend the documentation JUnit test to extract the literal marked fence, reject console writes, compile it with Java 8 source/target and annotation processing disabled, enable assertions, and invoke main, while retaining precise result-table regression assertions.

    Stop boundary: no production API, BaseContract algorithm or existing console side effect, bundled CSV content, standards interpretation or limits, PVT/flow-assurance models, notebook, index, external link, Huldra handoff material, generated inventory, release, or peer-head changes. One branch-attributable repair is available only for a hosted validation defect. The static PMD/SpotBugs code-health job should be impact-skipped because the frozen scope changes no production Java, POM, workflow, tool, or baseline; the always-on source/code-health contract remains required.

    Ownership and capacity: three positively identified autonomous implementation capabilities are active — #4915, #4916, and #4917 — so occupancy is 3/10, with ten both the target and absolute global ceiling. Contributor PRs #4872, #4876, and #4877 remain excluded from autonomous occupancy while participating in overlap checks. D260 is documentation/test-only, consumes no implementation slot, and its frozen paths overlap none of the three active implementation PRs. No other open #2499 PR exists.

    The guide contains one unique sales-contract-example: brazil-screen marker, one complete public GasSalesContractQuickStart, and no System.out or System.err call. The exact-source regression requires Java 8 source/target, disables annotation processing, enables assertions, invokes main reflectively, and retains the existing 12-column table assertions.

    Bounded audit evidence: the tutorial publishes a complete Java TegEquilibriumScreening, but its JUnit regression independently reimplements the same equilibrium-contact scenario rather than extracting, compiling, and executing the literal published source. The fence has no unique marker, and the published class/methods do not meet the current class-and-method Javadoc contract. The existing direct regression does provide strong engineering evidence for gas-water removal, water transfer, rich-liquid flow, phase count, water balance, and total mass balance.

    Acceptance contract: uniquely mark the complete Java 8 fence; add class and method Javadocs; keep Log4j2 and reject console writes; make the published program fail closed on finite gas-water values, more than 90% gas-phase water removal, the validated water-transfer and rich-liquid envelopes, multiphase contact, and water/total mass residuals. Extend the existing JUnit test to extract the exact marked fence, require the complete public class, compile it with Java 8 source/target and annotation processing disabled, enable assertions, and invoke main, while retaining the independent quantitative regression.

    Draft #4922 is open, draft, and mergeable from docs/d261-teg-tutorial-exact-source, based on exact frozen base 97c03ecf50d16a6dab7bd812364f49d5f4c5c444. Initial exact head was 4e2e7f11770d5285ebf7d1ab9f513489872cf54a. Connector read-back confirmed one append-only commit, exactly the two frozen paths, and zero behind the frozen base.

    The guide now contains the unique teg-equilibrium-example: conservative-contact marker and one complete public Java 8 TegEquilibriumScreening. It uses Log4j2 with no console writes and fails closed on finite wet/product gas-water values, more than 90% gas-phase removal, 22–25 kg/h water transfer, 3040–3050 kg/h rich-liquid flow, multiphase contact, and water/total mass residuals below 1e-8. The JUnit retains the independent quantitative regression and extracts, compiles with Java 8 source/target plus -proc:none, assertion-enables, and reflectively invokes the literal guide source. Guide blob is e0ddc8572c61d4f13251738a1c55cfa4b77413e9.

    Eight hosted workflow groups registered on the initial head: Production Optimization Documentation, Engineering Capability Coverage, Documentation Search, Pre-commit, Build/Test/Javadoc, Code Health, Spotless, and CodeQL. Code Health and Engineering Capability Coverage passed. No local Maven, Spotless, documentation-search, pre-commit, pre-push, Java execution, code-health, or Jekyll pass is claimed; hosted exact-head validation is authoritative.

    D261 exact hosted Spotless repair

    Initial pre-commit failed only because the new JUnit source differed from Google Java Format; its documentation-search hook passed after scanning 840 Markdown files and one HTML file. Successful Spotless workflow run 42432442293 produced artifact 13597817198, ZIP SHA-256 577f1fdbca579016caf2a9ef5241f29e13f36a7fbdc4d1c0c9b2724e9bbc08cd. Its patch touched only the frozen JUnit path and was applied exactly; resulting blob 7e59f53c99c008ebe3b75d034fa92b54463bf5ce matches the artifact target.

    Replacement exact head is 32aa6322512b75c80d72370e10103d78fd73cd57: two append-only commits, exactly the two frozen paths, and zero behind exact base 97c03ecf50d16a6dab7bd812364f49d5f4c5c444. Draft #4922 remains open, draft, and mergeable. The sole branch-attributable repair allowance is consumed. REPLACEMENT VALIDATION PENDING HOSTED CI. Preserve this exact head; no second repair, rebase, replacement, readiness transition, merge, close, abandonment, or peer-head change is permitted. Huldra handoff material remains unaffected.

    D261 replacement fast-validation checkpoint

    On unchanged exact head 32aa6322512b75c80d72370e10103d78fd73cd57, replacement pre-commit, Spotless, Engineering Capability Coverage, and Code Health pass. Code Health source contracts passed; static PMD/SpotBugs correctly impact-skipped after determining that the diff has no production Java, POM, workflow, tool, or baseline change. Agent-skill references and Java-change detection pass. Documentation search source contracts and documentation contract tests pass, with the Jekyll/search build active. Java 8/21 model specifications, Java 21 Javadocs, CodeQL, the production-optimization documentation workflow, and the remaining Build/Test/Javadoc matrix are active with no replacement-head failure signal.

    Draft #4922 remains open, draft, and mergeable. Reviews, conversation comments, and review threads are empty. Current autonomous implementation occupancy remains 1/10 from #4921; D261 is documentation/test-only and consumes no implementation slot. REPLACEMENT VALIDATION PENDING REMAINING HOSTED CI. The sole repair allowance is consumed; no second repair, rebase, replacement, readiness transition, merge, close, abandonment, or peer-head change was performed. Huldra handoff material remains unaffected.
