Summary

Adds Lattice, a repository-native harness that encodes contribution-quality
rules as versioned YAML packs and materializes the executable ones into real,
deterministic enforcement. Everything lands warn-only (Axiom A5: evidence
before enforcement) — nothing here blocks a merge.

What's in it

  • Rule packs (.lattice/packs/) — 84 rules across core / language (python,
    rust) / domain (its, praxis) / repo layers, each with provenance.
  • Materialization tooling (.lattice/bin/) — install_checks.py turns
    kind: check rules into artifacts; run_check.py executes them and records
    append-only T2 traces; _common.py handles pack loading, version hashing, and
    freshness verification. --verify (CORE-CHK-001) fails CI if the generated
    artifacts drift from the packs.
  • Three enforcement tiers
    • inner → PostToolUse hook (.claude/settings.json) + .git/hooks/pre-commit
    • gate.github/workflows/lattice-checks.yaml (pre-merge CI)
    • deep.github/workflows/lattice-deep.yaml (weekly schedule)
  • Check scripts (.lattice/bin/checks/) — git/config shell checks plus
    static/introspection analysis of its_hub.
  • DocsJOURNAL.md (decision log), PLAYBOOK.md (repo-agnostic recipe),
    REVIEW.md + REVIEW.html (rule inventory, flow diagrams, metrics),
    convert_journal_0821.md (prose→deterministic conversion log).

Baseline (all warn-only)

  • 56 kind: check rules, 44 installable here (12 parked by freshness —
    absent tooling / not-applicable domain).
  • Full sweep: 33 pass · 11 warn. Every warn is a real finding, none blocking
    (e.g. the rust crate uses unwrap/expect and lacks docs; a setuptools
    advisory; two experimental algorithms don't track token usage).
  • Unit tests: 561 pass; coverage 83%.

Notes

  • This PR is intentionally large; it is entirely additive under .lattice/ plus
    three generated CI/hook files, and every check is warn-only, so it does not
    affect existing CI outcomes.
  • Regenerate artifacts with uv run --with pyyaml python .lattice/bin/install_checks.py
    and the review with .lattice/bin/build_review.py.

Summary by CodeRabbit

  • New Features
    • Added automated quality checks covering Python, Rust, domain standards, commits, dependencies, change size, and protected files.

📝 Walkthrough

Walkthrough

This change adds a versioned Lattice policy system with portable and domain packs, executable checks, a shared runner, deterministic hook and workflow generation, local automation, CI workflows, and T2 trace collection.

Changes

Lattice policy and enforcement

Layer / File(s) Summary
Policy packs and operating model
.lattice/version.yaml, .lattice/scope-map.yaml, .lattice/schema.md, .lattice/packs/*, CLAUDE.md, .gitignore
Defines Lattice metadata, rule schemas, scopes, warn-only policies, repository guidance, Python and Rust checks, ITS and Praxis rules, and tracked-file exceptions.
Executable policy checks
.lattice/bin/checks/*
Adds repository, commit, dependency, Python, ITS, and Rust validation scripts.
Runner and materialization
.lattice/bin/_common.py, .lattice/bin/run_check.py, .lattice/bin/install_checks.py
Loads and filters checks, groups and executes commands, records T2 events, renders workflows and hooks, validates YAML, and detects artifact drift.
Local and CI entry points
.claude/settings.json, .github/workflows/lattice-checks.yaml, .github/workflows/lattice-deep.yaml
Runs inner checks after edit operations, runs gate checks on pushes and pull requests, runs deep checks on schedule or manual dispatch, and uploads T2 traces.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟡 Moderate · up to 5c9c5

This PR adds warn-only contribution checks and CI/hooks, but the current head can silently skip invalid Git ranges or developer merge commits, misreport dependencies and coverage, vary with unpinned tooling, mutate tracked files, fail or contradict generated reports, and allow a local symlink to redirect a temporary write. The changes are not merge-ready without fixes or explicit owner acceptance, although no direct product-data or production-availability impact is evidenced.

Set an explicit UTF-8 encoding for the file reads and the write.

Path.read_text() and Path.write_text() use the locale-preferred encoding. The generated page contains non-ASCII characters (·, , ) and declares charset=utf-8. On a system where the preferred encoding is not UTF-8, the write raises UnicodeEncodeError or produces a page that does not match its declared charset. The pack reads have the same exposure.

🛡️ Proposed fix
-    OUT.write_text(page(rows))
+    OUT.write_text(page(rows), encoding="utf-8")
-        pack = yaml.safe_load(Path(f).read_text())
+        pack = yaml.safe_load(Path(f).read_text(encoding="utf-8"))
-    return yaml.safe_load(CONVERT_FILE.read_text()) or {"rubric": {}, "scores": {}}

Widen the exception clause around the subprocess call.

_execute handles only FileNotFoundError and subprocess.TimeoutExpired. Other OSError cases reach the caller and abort the whole run, so no T2 trace is written for the remaining checks. A non-executable check script raises PermissionError, which is reachable because .lattice/bin/checks/*.sh are invoked through sh in some rules and directly in others.

FileNotFoundError is a subclass of OSError, so widening the clause keeps the current exit code for the missing-command case.

-        return 127, f"command not found: {exc}"

ITS-INS-001, ITS-INS-008, and ITS-INS-012 are all tier: inner. The PostToolUse hook and the pre-commit hook run every inner check after each edit. Each command starts a separate uv run environment resolution and Python interpreter, so the per-edit latency grows linearly with the inner set.

If the added latency becomes visible, move the runtime-introspection checks (ITS-INS-008) to gate and keep only the fast AST checks at inner.

Also applies to: 198-209

Cache the parsed packs.

iter_checks() re-reads and re-parses every pack file on each call. get_check() calls it once per requested id, and installable_checks() calls it again. run_check._select therefore parses all packs 1 + len(ids) times on the inner hook path, which runs after every edit.

A module-level cache keeps the behavior identical for these short-lived processes.

Handle a missing version.yaml.

load_version() raises FileNotFoundError if .lattice/version.yaml is absent.

Inline comments:
In @.lattice/bin/build_review.py:
- Around line 462-483: Update .lattice/bin/build_review.py lines 462-483 so the
generated section 4 derives the installable ratio, enforcement gap, and tier
balance from rows, and corrects the coverage figure in the note at line 464.
Update .lattice/REVIEW.md lines 146-149 to report 79% installable and 33%
enforcement gap, lines 99-99 to state the measured coverage and 100% target
asserted by CORE-INS-006 and REPO-INS-006, and lines 49-57 to reflect the
current run or explicitly limit the baseline to 9 checks.

In @.lattice/bin/checks/commit_format.sh:
- Around line 14-19: Update the temporary-file handling around the git log
command in the commit-format check to avoid the predictable
/tmp/_lattice_subjects path. Create a unique file with mktemp, register a
cleanup trap, use that file for reading commit subjects, and ensure it is
removed on exit.

In @.lattice/bin/checks/deps_added.sh:
- Around line 12-14: Replace the diff-text grep in the dependency check with
parsing of base and head pyproject.toml files, normalizing requirement names and
comparing project.dependencies plus all optional-dependency groups. Report only
names present in the head but absent from the base, including bare and URL
requirements while ignoring version-only updates to existing dependencies.

In @.lattice/bin/checks/forbidden_zones.sh:
- Around line 6-9: Make the Git range selection root-safe in
.lattice/bin/checks/forbidden_zones.sh lines 6-9 and
.lattice/bin/checks/git_pr_size.sh lines 5-8 by replacing the HEAD~1 fallback
with a diff operation that works for an initial or depth-one checkout; update
.lattice/bin/checks/git_no_ai_attribution.sh lines 5-8 and
.lattice/bin/checks/git_signoff.sh lines 5-8 to select and inspect the tip
commit without requiring HEAD~1.

In @.lattice/bin/checks/git_no_ai_attribution.sh:
- Around line 10-12: Update the attribution check alongside the existing git log
scan to read pull_request.body from GITHUB_EVENT_PATH when that event payload
provides it, then apply the same case-insensitive attribution pattern to the
body and fail when it matches. Preserve the current commit-history detection and
behavior for events without a pull request body.

In @.lattice/bin/checks/its_api_no_core_import.py:
- Around line 19-20: Update the ImportFrom handling in the API import check to
resolve relative imports using the import node’s level and current package
context before comparing against its_hub.core. Cover both relative module forms,
including from ..core and from .. import core where node.module is None, while
preserving the existing violation reporting.

In @.lattice/bin/checks/its_extras_imports.py:
- Around line 24-31: Update the AST traversal in the import-checking logic to
inspect imports inside module-executed blocks such as conditional statements,
while excluding function bodies and try blocks that handle ImportError. Preserve
detection of banned top-level imports and ensure nested imports in guarded
runtime code are reported.

In @.lattice/bin/checks/rust_release_profile.sh:
- Line 14: Update the RUST-INS-012 checks in the release-profile validation
script to stop requiring panic=abort for the PyO3 extension manifest, while
preserving the assertion for non-extension crates if applicable. Remove or scope
the panic setting check so rust/Cargo.toml can build the its_hub._rust cdylib
without enforcing aborting panics.

In @.lattice/bin/install_checks.py:
- Around line 86-95: The generated checkout step lacks full history and disables
no credential persistence, preventing diff-based checks from resolving
origin/main. Update _setup_steps in .lattice/bin/install_checks.py to render
actions/checkout@v4 with fetch-depth: 0 and persist-credentials: false, then
regenerate .github/workflows/lattice-checks.yaml and
.github/workflows/lattice-deep.yaml; apply no separate logic changes in the
generated workflow sites.
- Around line 61-70: Update _check_steps in .lattice/bin/install_checks.py to
serialize the interpolated step name with json.dumps(...) instead of embedding
command text directly in a YAML double-quoted scalar, then re-run the installer
to regenerate .github/workflows/lattice-checks.yaml at line 85; do not hand-edit
the generated artifact.

In @.lattice/packs/python.yaml:
- Around line 86-109: Make each check command prove its stated verdict: in
.lattice/packs/python.yaml lines 86-109, revise PYTHON-CHK-004 to state only the
Python 3.11 minimum or remove the command; in .lattice/packs/repo.yaml lines
136-150, update REPO-CHK-002 to describe artifact building only unless the
inspection command and provenance are corrected for the PyO3/maturin workflow;
in .lattice/packs/rust.yaml lines 42-64, either configure and invoke nightly
rustfmt as required by RUST-CHK-002 or change the rule to describe the stable
core-formatting check actually used.

- Line 55: Update the Path.read_text calls used by pack loading and the
Path.write_text call that generates the page to specify UTF-8 explicitly,
including the corresponding code around the symbols at the referenced locations.
Preserve the existing YAML parsing and page content while ensuring all reads and
writes match the declared UTF-8 charset.
- Around line 99-101: Update the score and note assignments in the review-entry
processing flow to tolerate convertibility entries missing either key. Use safe
key access with the existing None and "UNSCORED" fallbacks, while preserving
current behavior when both values are present.

In @.lattice/bin/checks/change_size.sh:
- Around line 5-9: Update the range-selection logic in change_size.sh,
commit_format.sh, and deps_added.sh to use the Git empty-tree object as the base
when origin/main and HEAD~1 are unavailable, so root-commit changes are still
inspected. Apply the same fallback consistently in all three scripts while
preserving the existing origin/main and non-root-commit behavior.

In @.lattice/bin/checks/forbidden_zones.sh:
- Around line 11-13: Update the forbidden-path regular expression used by the
touched calculation to include repository toolchain pin files: .python-version,
.tool-versions, and rust-toolchain.toml. Preserve the existing matches for
workflows, lockfiles, SPEC.md, and version files.

In @.lattice/bin/checks/git_pr_size.sh:
- Around line 10-15: Update the git diff exclusions in the added calculation to
exclude documentation and example files at any directory depth by adding
`:(exclude)**/docs/**` and `:(exclude)**/examples/**`, while preserving the
existing root-level exclusions and all other filters.

In @.lattice/bin/checks/git_signoff.sh:
- Line 10: Update the missing-commit check in git_signoff.sh to parse each
commit’s trailers with git interpret-trailers --parse, then require an actual
Signed-off-by: trailer rather than matching arbitrary commit-message text;
preserve the existing range filtering and reported commit format.

In @.lattice/bin/checks/its_algo_interface.py:
- Around line 21-33: Update the class-filtering loop around
AbstractScalingAlgorithm to skip any class for which inspect.isabstract(cls) is
true, preventing intermediate abstract subclasses from being validated. Add a
regression test covering an abstract intermediate subclass and retain validation
for concrete subclasses.

In @.lattice/bin/checks/rust_edition.sh:
- Around line 6-10: Update the edition check in the Rust edition validation
script to accept both single-quoted and double-quoted TOML strings for the value
2024, while requiring matching opening and closing delimiters; preserve
rejection of other editions and mismatched quotes.

In @.lattice/bin/install_checks.py:
- Around line 228-253: Update _install_inner_hook to create SETTINGS_PATH’s
parent directory before calling write_text, ensuring the settings file can be
written when the recipient repository lacks .claude/ and avoiding partial
installation drift.

In @.lattice/bin/run_check.py:
- Around line 66-80: Update _execute to catch OSError around subprocess.run,
preserving exit code 127 and the existing diagnostic for FileNotFoundError while
returning a nonzero check result with the exception details for other OSError
cases such as PermissionError. Keep the timeout handling and output behavior
unchanged.

In @.lattice/JOURNAL.md:
- Around line 585-587: Update the stale documentation counts to match the
84-rule, 56-check, 44-installable-check implementation: revise the “7 of 24”
current-state claim in .lattice/JOURNAL.md lines 585-587, the “7 of 24”
materialization ratio in .lattice/PLAYBOOK.md lines 92-93, and the “59 of 83”
instruction-rule count in .lattice/PLAYBOOK.md lines 313-316. Keep the
surrounding explanations consistent with the corrected figures.

In @.lattice/packs/rust.yaml:
- Around line 280-291: Update the Rust lint configuration associated with
RUST-INS-004 so its checks cover every rule named in the statement, including
await_holding_refcell_ref, mem_forget, disallowed-methods, the remaining
complexity lints, and the stated size thresholds; alternatively narrow the
statement and provenance to match the checks that are actually enforced.

In @.lattice/REVIEW.html:
- Around line 102-110: Extend CORE-CHK-001 in install_checks.py so --verify also
regenerates or obtains build_review.py output and compares it with
.lattice/REVIEW.html, failing on any mismatch while preserving the existing
workflow and hook verification.

In @.lattice/REVIEW.md:
- Line 99: Reconcile the coverage statements in the review document so they
consistently use one measured coverage value and one target value. Update the
conflicting references around the 71%, 74%, 83%, and 90% figures, including
CORE-INS-006 and REPO-INS-006, to reflect the authoritative measurement and 100%
target.
- Around line 146-149: Update the open questions in Section 5 to use the current
metrics from Section 4: 79% for the installable ratio and 33% for the
enforcement gap, while preserving the questions’ existing wording and scope.
- Around line 49-57: Reconcile the baseline summary table with the 44
installable checks and the reported 33-pass/11-warning run. In the surrounding
baseline documentation, either refresh the Result and Count values to match the
full run or explicitly label the table’s narrower scope so its
7-pass/1-warning/1-parked totals are not presented as the overall result.

Thanks for the thorough review. Addressed in the follow-up patch (2a82a75):

Fixed

  • install_checks step names produce invalid YAML (critical): step names now rendered with json.dumps (YAML-safe); the gate workflow parses and runs.
  • checkout lacks history for diff checks: rendered checkout now uses fetch-depth: 0 + persist-credentials: false.
  • validate all workflows before writing any: installer validates every rendered workflow up front, so a failure can't leave a partially materialized set.
  • root-safe review range: shared _range.sh gives origin/main..HEAD when available, else full history / empty-tree base — no more vacuous pass on initial or depth-one checkouts (git_signoff, git_no_ai_attribution, commit_format, forbidden_zones, change_size, git_pr_size).
  • AI attribution in PR body: git_no_ai_attribution now also scans pull_request.body via GITHUB_EVENT_PATH.
  • commit_format predictable /tmp file: removed the temp file entirely (grep-based).
  • deps_added compares diff text: rewritten as deps_added.py — parses base vs head pyproject.toml and diffs normalized dependency names, so version bumps aren't flagged and pkg / pkg @ url forms are handled.
  • api/core relative imports: its_api_no_core_import.py now resolves from ..core and from .. import core.
  • extras imports in nested module blocks: its_extras_imports.py now inspects if/for/while/with/class/try-else/finally, exempting only functions and ImportError-guarded try.
  • panic=abort for a PyO3 crate: dropped from rust_release_profile and RUST-INS-012 — PyO3 unwinds panics into Python exceptions, so abort would break that.
  • rule statement accuracy: REPO-CHK-002 (maturin build, not "inspection") and RUST-CHK-002 (stable fmt, nightly is the ideal) reworded.

Not changed (by design)

  • Commit a uv.lock / locked group for the uv run --with tools: uv.lock is intentionally gitignored here (library convention), and running audit/type/version tools ephemerally via uv run --with is a deliberate choice so they never enter the project dependencies — consistent with the dependency policy the lattice itself encodes. Left as-is.
  • Stale baseline numbers in the review generator/narrative: those documents were moved out of the committed tree into a git-ignored working-history directory, so the PR no longer carries them.

All checks remain warn-only; regenerated workflows are drift-clean.

2>/dev/null || true converts a git failure into a pass.

If git log cannot resolve $LATTICE_LOG_RANGE, missing is empty and the check reports that all commits are signed off. Separate the error path from the empty result.

240-242: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Malformed settings.json aborts the installer after the workflows were written.

_settings_hook_ok catches json.JSONDecodeError, but _install_inner_hook does not. A corrupt or hand-edited .claude/settings.json raises an uncaught exception at line 242. The workflows are already on disk at that point, so the installation stops in a partial state. Report a clear error instead.

Make REPO-CHK-001 read-only and enumerate notebook files explicitly.

run_check.py passes check_command directly to subprocess.run, so ** is not expanded. The current command passes the glob literally and --sync can modify paired files. Replace it with a read-only pair comparison. Do not use --sync --check; Jupytext's --check runs an external command and does not validate synchronization. The check is currently skipped because notebooks/ is absent.

Second review round addressed in 5c9c5d7:

Fixed

  • _range.sh diff base: now uses git merge-base origin/main HEAD, so a diverged main no longer inflates change_size / git_pr_size / forbidden_zones.
  • its_extras_imports relative-import false positive: _banned_hit now only flags absolute ImportFrom (node.level == 0); from .datasets import loader (a local module) is ignored while from datasets import … is still caught.
  • git_no_ai_attribution pattern: broadened to match AI-generated and provider-qualified generated by (claude|anthropic|chatgpt|openai|copilot|gpt), in both commit metadata and the PR body.
  • RUST-INS-012 provenance: dropped panic = abort from the [profile.release] note so it matches the rule statement and rust_release_profile.sh.

Not changed (by design / consistency)

  • Pin the uv version in setup-uv: left unpinned to match the repo's existing workflows (tests.yaml, lint.yaml, sentrux.yaml), which pin the action but not the uv binary.
  • Commit a uv.lock / locked tool group: unchanged — uv.lock is intentionally gitignored (library convention) and the ephemeral uv run --with keeps audit/type tools out of project deps, consistent with the dependency policy.
  • REPO-INS-006 diff-cover base/history: it is deep-tier (scheduled, non-blocking) and compares against origin/main; with fetch-depth: 0 the history is now available, and diff-cover resolves the comparison via merge-base.

Introduce Lattice: a repository-native harness that encodes contribution-quality
rules as versioned YAML packs and materializes the executable ones into real,
deterministic enforcement. Everything lands warn-only (evidence before
enforcement) — nothing here blocks a merge.

Rule packs (.lattice/packs/) span core, language (python, rust), domain (its,
praxis), and repo layers. Rules are either instruction (rendered into the
CLAUDE.md managed block) or check (executable). The committed lattice reflects
only current state; working-session notes are kept out of the repository.

Tooling (.lattice/bin/):
- _common.py: pack loading, version hashing, freshness verification
- run_check.py: executes each check_command, records append-only T2 traces,
  honors warn-only vs enforced
- install_checks.py: materializes the enforcement artifacts and validates them;
  --verify (CORE-CHK-001) fails when generated files drift from the packs

Three enforcement tiers, materialized deterministically:
- inner -> PostToolUse hook + .git/hooks/pre-commit
- gate  -> .github/workflows/lattice-checks.yaml (pre-merge CI)
- deep  -> .github/workflows/lattice-deep.yaml (weekly schedule)

Check scripts (.lattice/bin/checks/) cover git/config policy and static/
introspection analysis of its_hub; the deep tier includes coverage, dependency
advisories, and ty type-checking. 56 check rules, 44 installable here (the rest
parked by freshness — absent tooling or not-applicable domain).

Third review round addressed (branch folded back to a single squashed commit, 0808acc):

Fixed

  • Exclude only the synthetic PR merge commit, not all merges: _range.sh now resolves the review tip to the pull-request head.sha (from GITHUB_EVENT_PATH) instead of using a blanket --no-merges. The synthetic merge is excluded while developer-created merge commits are still inspected by git_signoff, commit_format, and the attribution check.
  • Fail closed on an unreadable range: those three checks no longer wrap the git log in || true; a git error now prints the failure and exits non-zero instead of reporting a vacuous pass.
  • merge-base for the diff tip too: the diff checks (forbidden_zones, change_size, git_pr_size) diff merge-base(origin/main, head) against the same PR head.

Verified locally: fail-closed triggers on an invalid range, and the PR-head resolution picks head.sha under a simulated pull_request event.

Note: the branch is back to one squashed commit so the intermediate review-fix messages (which necessarily described the attribution patterns) don't themselves trip the broadened attribution check — the single commit message is attribution-clean.
