Summary

kani-smoke now runs its 15 harnesses on a pull request only when the pull
request changes one of their inputs. Pushes to main, a new nightly schedule
and manual dispatches still run every harness. The job stays a required check
that runs and reports on every trigger. It is never skipped by a paths
filter or a job-level if:.

From 1 to 21 September, kani-smoke made 534 runs and used 3,696 minutes,
about seven minutes a run. Of the 300 most recent merges to main, 129 (43%)
change no path in the new scope; in September the figure is 42 of 86.

Changes

  • Decision step. The job runs checkout (fetch-depth: 2), then setup-uv,
    then Decide Kani proof scope, which runs scripts/kani_proof_scope.py
    (cyclopts, cuprum). The step diffs the merge commit against HEAD^1 with
    --no-renames and writes run-proofs. Every later step (cache restore,
    setup-rust, Kani install, version check, harnesses, cache save) carries
    if: steps.scope.outputs.run-proofs == 'true'.
    • Any event other than pull_request always runs the proofs.
    • An unreadable change set runs them.
    • A malformed scope file fails the step.
    • A skipped run is green and explains itself in the job summary and a
      notice.
  • Nightly schedule. 41 4 * * * (04:41 UTC, clear of the 03:05
    mutation-testing run). build-test and windows carry
    if: github.event_name != 'schedule'. kani-smoke keeps the fork-fallback
    runner expression from Let a fork's pull request reach a runner it can have #728, so it runs on the same runner as before on
    every trigger.
  • Scope. tools/kani/proof-scope.toml has two lists:
    • sources: the harnesses' module closure, 44 files in 18 entries (src/ir/,
      src/ast/, src/ninja_gen*, localization and locales/, hasher,
      hex, recipe_shell, shell_word, lib.rs).
    • infrastructure: Cargo.toml, Cargo.lock, rust-toolchain.toml,
      build.rs, .cargo/, tools/kani/, the kani-cache action, the
      Makefile, ci.yml and the script.
  • Contracts.
    • kani_proof_scope_test.py recomputes the closure from the Rust source,
      using rust_module_graph.py and rust_module_closure.py. The closure
      follows paths, use groups, macros, impls, includes and declaring
      ancestors; cfg(test) code is excluded, and --tests is refused. The
      contract fails when any #[kani::proof] file, or any file the harnesses
      reach, is outside the scope, when an entry reaches past the closure, or
      when an infrastructure input is dropped.
    • rust_module_closure_test.py pins each closure rule on a synthetic crate.
    • kani_smoke_scope_wiring_test.py pins the job shape: no job if:, no
      trigger path filters, only checkout and uv before the decision, and the
      exact condition on every later step.
    • kani_proof_scope_decision_test.py drives the script against real git
      merge commits and as a child process.
  • Existing contracts. timeout_ordering_test.py now pins
    build-test's new job condition beside the coverage step's.
    release_dry_run_smoke_test.py (from Skip the duplicate Windows smoke on release dry runs #771) required no condition at all
    on ci.yml's Windows call; it now admits exactly
    github.event_name != 'schedule', which is true on every pull request,
    and still refuses any other condition.
  • Docs. ADR-039, a "Change-scoped Kani proofs" section in the developers'
    guide, and updates to the contents, the repository layout and the formal
    verification notes.

Mutation proof

The ledger has 55 mutations. Each one fails its named test:

  • Scope: dropping a reached file; adding a harness under src/manifest or
    in tests/; a harness reaching crate::stdlib; widening to src/; adding
    an unreached or dead entry; dropping Makefile or Cargo.lock; adding
    --tests.
  • Closure: removing each rule, and each exclusion.
  • Wiring: removing or changing the harness condition; a job if:; a paths
    filter; a conditional decision; dropping fetch-depth; removing the
    schedule; build-test running on the schedule; a chained decision command;
    moving the cache restore before the decision.
  • Closure: resolving self:: from the crate root, and dropping the
    final-segment rule (use crate::tail; then tail:: from a nested module).
  • Decision: each branch, including a scalar string or an empty string
    standing in for a path list, and the script deciding every event as a pull
    request or skipping every event other than a pull request.
  • Windows gate: a push-only condition, a null condition, and a disjunct
    excluding pull requests each fail the dry-run smoke contract.

The mutation runs also found three defects. An include followed by a method
call inside a cfg(test) body was mis-read; a scope key holding a string
rather than a list was read as a list of characters; and resolving self::
from the crate root survived. Each is fixed, and a test now covers it.

Validation

make check-fmt, make lint, make typecheck, make doc-coverage,
make test, make markdownlint and make nixie pass locally on main at
ebcedae. After the rebase onto 7305514, which brought in #728 and no Rust
change, make test-workflow-contracts (846 passed), make lint-python,
make github-actions-lint, make check-fmt and make markdownlint pass
again. The only conflict was build-test's header in ci.yml, resolved by
keeping #728's fork-fallback runs-on and adding the schedule exclusion.

Measurements to follow the merge

  • A pull request touching no scope path: the job's duration and conclusion.
  • A pull request touching src/ir/: a full run.
  • The first push-to-main run.
  • The first nightly run.

Summary by Sourcery

Run Kani proofs selectively for pull requests while preserving full verification on mainline, nightly, and manual workflow runs.

New Features:

  • Add change-scoped execution for the required Kani proof job, running harnesses on pull requests only when proof inputs change while retaining full runs for pushes, nightly schedules, and manual dispatches.

Bug Fixes:

  • Prevent required checks from being skipped by workflow path filters or job-level conditions while ensuring unreadable change sets and malformed scope data are handled safely.

Enhancements:

  • Derive and validate the Kani proof input scope from the Rust module closure and protect the workflow decision with behavioral, property-based, and mutation-tested contracts.

Build:

  • Add pinned Python dependencies needed by the proof-scope decision and workflow contract tooling.

CI:

  • Add a nightly Kani schedule, gate non-Kani jobs out of the nightly run, and condition all proof-related work on the scope decision.

Documentation:

  • Document the change-scoped Kani proof design, adoption guidance, repository layout, and formal verification behavior.

Tests:

  • Add decision, scope, Rust module graph and closure contracts, including property-based and mutation-focused coverage; update existing workflow contracts for the nightly conditions.

Chores:

  • Add the Kani proof scope manifest covering source and infrastructure inputs.

Summary

  • Run all 15 Kani harnesses on pushes to main, nightly schedules and manual dispatches. On pull requests, run them only when changed paths overlap the configured proof or infrastructure scope.
  • Keep kani-smoke active for every trigger. If a pull-request change set cannot be read, run the proofs. If no scoped paths changed, skip the proof steps and report the reason.
  • Define the scope in tools/kani/proof-scope.toml. Add Rust module-closure, scope-decision and workflow-wiring contracts.
  • Schedule the nightly run for 04:41 UTC. Exclude scheduled runs from build-test and windows.
  • Add ADR-039 and update the developer and formal-verification documentation.

The author reports 846 workflow-contract tests passed before the Hypothesis tests were added. The reviewer did not run repository tests. The author also reports 534 kani-smoke runs using 3,696 runner minutes from 1–21 September, and that 129 of the 300 most recent merges changed no path in the configured scope.

Walkthrough

The change adds a source-checked scope for Kani proof inputs and a script that decides whether proofs run. CI keeps the kani-smoke check available across events, skips proof steps on out-of-scope pull requests, and adds a nightly schedule. Contract tests and documentation cover the scope and workflow rules.

The script validates the scope file, checks pull-request changes against it, and publishes the proof decision. Tests cover scope parsing, path matching, Git results and workflow outputs. Documentation describes the proof policy and local checks.
Scheduled workflow integration
.github/workflows/ci.yml, tests/workflow_contracts/kani_smoke_scope_wiring_test.py, tests/workflow_contracts/release_dry_run_smoke_test.py, tests/workflow_contracts/timeout_ordering_test.py, tests/workflow_contracts/nextest_lane_rules.py, tests/workflow_contracts/nextest_lane_mold_test.py, docs/developers-guide.md
CI adds a nightly schedule and excludes scheduled runs from selected jobs. The kani-smoke job runs its setup and proof steps only when the scope decision is true. Workflow contracts and documentation cover the schedule and job conditions.

Priority: ➖ Normal

Change: Feature

Merge Risk: 🔵 Low · up to 0ef18

The proof gate’s documentation needs two small corrections, but the previously reported risk of skipping proofs because of a rooted import has been fixed. The change is mergeable with those corrections tracked.

Full details: Unit Architecture

Explanation

The change separates decide from publish, but it leaves read failures implicit at new query boundaries. read_scope() wraps OSError and TOML errors as ScopeFileError, but Path.read_text(encoding="utf-8") can also raise UnicodeDecodeError, which is neither documented nor wrapped. The new read_crate() path has the same issue: _file_views() reads source files directly, while read_crate() documents only ModuleGraphError; permission, decoding, or other read errors escape as raw exceptions. The added tests cover missing and malformed scope files, but do not cover these read failures. This makes environmental fallibility less visible than the repository's existing reader boundaries.

Resolution

Wrap all repository reads at their boundary. Update read_scope() to convert UnicodeDecodeError as well as OSError and TOML parse errors into ScopeFileError, with the path and chained cause. Update _file_views()/read_crate() to convert file-read and UTF-8 decoding failures into a documented ModuleGraphError (or a dedicated CrateReadError) with the affected path and chained cause. Add tests for invalid UTF-8 and an injected read failure, and document the complete exception contract.

Full details: Observability

Explanation

The pull request changes CI resource consumption by adding a nightly Kani run and conditionally skipping costly proof steps on pull requests. The workflow and scripts/kani_proof_scope.py provide logs, a notice, and a job summary for each decision, but the diff adds no metric or metric artefact for run/skip outcomes, proof duration, or resource consumption. This does not meet the explicit metrics requirement for changes that affect resource consumption.

Resolution

Add a bounded metrics record for each Kani decision and proof execution. Include stable fields such as event category, decision outcome, decision reason category, and elapsed time. Record proof success or failure and resource usage where the CI platform exposes it. Upload or publish the metric artefact for later analysis. Do not use changed file paths, request identifiers, or free-form errors as metric labels; keep those details in bounded logs or the job summary.


Nightly proofs wake at dawn,
Changed paths lead the way.
Scope lists guard the harness,
Git reports what moved.
Green checks still appear,
When proof steps rest today.

Reviewer's Guide

The PR preserves kani-smoke as an always-reporting required check while moving proof execution behind a contract-tested, conservative scope decision based on the pull request merge diff; it also adds nightly full verification, derived scope validation, and supporting documentation.

File-Level Changes

Change Details Files
Added an in-job, fail-safe decision mechanism that conditionally runs Kani proofs while preserving the required check on every trigger.
  • Run checkout with the merge commit’s first parent, install uv, and execute the scope decision script before proof-related work.
  • Condition cache, Rust/Kani setup, version checking, harness execution, and cache saving on the decision output.
  • Run proofs for all non-pull-request events, and run them on pull requests when the diff touches scope or cannot be read; otherwise publish a green skip explanation.
  • Reject missing or malformed scope data instead of making an unsafe decision.
.github/workflows/ci.yml
scripts/kani_proof_scope.py
Introduced a derived proof-input scope and contracts that keep it complete, precise, and aligned with the Kani invocation.
  • Define source and infrastructure inputs in a TOML scope file.
  • Build a Rust module graph and conservative dependency closure covering module paths, use groups, macros, impls, includes, ancestors, Kani sites, and global allocators while excluding test-only code.
  • Verify harness files, reached files, infrastructure inputs, and the prohibition of test compilation flags.
  • Pin closure behavior with synthetic-crate tests and decision behavior with real merge-commit and child-process tests.

Added workflow-shape and scheduling safeguards for the required Kani gate.
  • Add a 04:41 UTC nightly trigger that runs the Kani job alone.
  • Exclude build-test and Windows jobs from the nightly schedule.
  • Enforce no trigger path filters or kani-smoke job condition, and require the exact condition on every later Kani step.
  • Extend timeout-ordering coverage for the build-test schedule condition.

@coderabbitai Head 8f95385 carries the fix for your final-segment thread, which you have confirmed and resolved. It is rebased onto main at ebcedae. CI and the CodeScene checks are green at this head, and no threads are open. Could you look over the changes since your review at 44afd20, and tell me whether anything in them, or in your pre-merge checks table, still needs attention before this merges?

@leynos, address the pre-merge table’s Testing (Overall) error before merging if you want that check satisfied. At head 8f95385, tests/workflow_contracts/kani_proof_scope_decision_test.py tests push, schedule, and workflow_dispatch through decide(), but its child-process helper still sets INPUT_EVENT_NAME to pull_request. Add a child-process case for each non-pull-request event. Assert run-proofs=true in the output file and the run heading in the summary. This will test that main() passes the event to decide().

I inspected the PR-only changes since the reviewed state. The final-segment fix now reaches src/tail.rs from the nested use crate::tail fixture. The helper split adds a check that rejects a scalar scope list. The Windows contract permits only the nightly schedule exclusion, which remains true for pull requests. I found no further issue in those changes.

The table’s property-testing and observability items remain warnings, not required fixes. The table has not been refreshed for this head. GitHub reports green CI and CodeScene checks, no unresolved threads, and a clean merge state. It still reports CHANGES_REQUESTED from my earlier review; the listed main rules require status checks but show no review requirement.

@leynos, add the missing child-process tests before merging if you want the pre-merge Testing (Overall) error cleared. At head 8f95385654b9acfc0c492d14a36035be8cbd1c4e, the tests call decide() for push, schedule, and workflow_dispatch, but _run_script() still sets INPUT_EVENT_NAME to pull_request. Test each non-pull-request event through the script. Assert run-proofs=true in the output file and Kani proofs run in the summary.

I checked the three later commit patches through GitHub. The final-segment change adds src/tail.rs to the nested-import fixture. The helper split rejects scalar scope lists. The Windows contract accepts only the nightly schedule exclusion. I found no further issue in those patches.

The pre-merge table marks property testing and observability as optional warnings. GitHub reports a clean, mergeable head and no unresolved threads. The reported CI and CodeScene checks succeeded. The review decision remains CHANGES_REQUESTED, so do not treat the clean merge state as review approval.

@leynos, do not merge head 6f662570822035c5cf8f605d90c8bacc5603dd5e yet. Complete the property-testing work, give the observability finding a concrete disposition, and wait for current-head CI.

Treat both warnings as required work. My earlier description of those warnings as optional was insufficient. Thanks for the guidance.

Verdict at this head

Item Assessment Required action
Testing (Overall) Satisfied by inspection. The new child-process test covers push, schedule, and workflow_dispatch. Each case uses an out-of-scope diff and checks run-proofs=true, the run heading, and the event name. Confirm that current-head CI passes these tests.
Testing (Property / Proof) Still outstanding. The module readers still rely on the fixed synthetic crate and example-based cases. No Kani-specific Hypothesis coverage is present. Add generative tests in this PR. The closure algorithm controls whether proofs run, so this work belongs here.
Observability Still outstanding. Notices and summaries explain individual decisions, but no retained metric records decisions, proof duration, or failure outcomes. Implement the metric contract, or open the scoped follow-up issue below and explicitly accept that disposition before merging. Do not leave the warning untracked.
Current-head CI Pending. CodeScene passed. build-test, kani-smoke, netsukefile, and Windows checks remain running or queued. Wait for the required checks at this head.
Review state No unresolved threads. GitHub still reports CHANGES_REQUESTED and merge state BLOCKED. Obtain a fresh review after the outstanding work. Do not treat thread resolution as approval.

The published pre-merge table still contains the old Testing (Overall) error. This assessment corrects that stale entry; it does not update the table automatically.

Changes checked

The kani-smoke setup-rust pin matches main:

4fb8eb7ad52454678a0662865d81d3cd17aa6e0e

Its scope if: remains intact. The rebased wrapper and mutation-gate steps also share that condition. The scope now includes their test inputs and mutation patches. The new contract checks mutation patch targets.

The shared-guard rule has positive and negative tests. The negative test removes the mutation-gate condition and requires rejection. The final-segment regression fixture still reaches src/tail.rs.

I found no additional defect in those changes. I inspected the code and contracts. I did not run repository tests.

AI agent prompt: complete the property-testing work

Work on leynos/netsuke PR #774, starting from head
6f662570822035c5cf8f605d90c8bacc5603dd5e.

Add Hypothesis coverage for:
- tests/workflow_contracts/rust_module_graph.py
- tests/workflow_contracts/rust_module_closure.py
- scripts/kani_proof_scope.py

Generate bounded file-backed Rust module graphs and supported reference forms.
Include rooted paths, final-segment imports from nested modules, grouped
imports, child paths, macro calls, impl headers, literal includes, declaring
ancestors, and test-only modules.

Build a small independent graph oracle. Do not derive expected results with
the production parser or its regular expressions. Check that every required
dependency is reached. Account explicitly for documented conservative
over-approximation.

Check monotonicity when adding supported references or seeds, stability under
declaration and traversal order, and exclusion of test-only dependencies.

Generate unsupported layouts and require ModuleGraphError. Generate scope
entries and changed paths. Check exact-file matching, directory boundaries,
decision order independence, and conservative unreadable-diff behaviour.

Keep generators small and shrinkable. Retain the existing regression tests.
Use the Hypothesis dependency already installed by test-workflow-contracts.
Do not weaken the scope or wiring contracts.

Run the workflow-contract suite and the required Python formatting, lint,
and type checks in the authorized development environment. Report commands,
results, and any remaining limitations.

Proposed GitHub issue: retained Kani workflow metrics

Track the metrics pipeline separately from the proof-selection algorithm. I found no matching issue. Closed #627 covers release-admission metrics, not Kani metrics.

Title: Add retained, bounded metrics for kani-smoke

Add retained metrics for the Kani workflow introduced by PR #774.

Affected areas:
- .github/workflows/ci.yml
- scripts/kani_proof_scope.py
- Workflow-contract tests
- Developer documentation

Record the proof decision, proof execution outcome, and proof duration.
Distinguish out-of-scope skips, unreadable diffs, invalid scope files, and
proof failures with a fixed vocabulary. Record cache hit/miss only where
the cache action exposes that information reliably.

Deliver metrics on successful, skipped, and failed paths where the runner
can execute the finalizer. Document cancellation and job-timeout limitations.
Use an explicit artifact retention period or an established metrics sink.

Keep event and outcome labels bounded. Exclude paths, commit IDs, run IDs,
URLs, and free-form errors from metric labels.

Add behavioural tests and workflow contracts for emission, failure handling,
delivery, retention, and label cardinality. Update the wiring contract to
permit an unconditional metrics finalizer without weakening proof-step guards.

Acceptance criteria:
- Run, skip, unreadable-diff, invalid-scope, and proof-failure cases have tests.
- Proof duration is recorded when proof execution starts.
- Metrics survive normal step failures.
- Documentation defines the schema, retention, and operator use.

Head 927de20 answers both pre-merge warnings from the review at 6f66257.

Testing (Property / Proof): added rust_module_closure_property_test.py and kani_proof_scope_property_test.py. The closure tests render small flat crates from an explicit edge list and compare the production closure with graph reachability over that list, not a second parse. They cover every reference form (rooted, final-segment, group, macro), literal includes, test-only exclusion, stability under declaration and line order, monotonicity when a reference or seed is added, a chain family where each link is the only route to the next module, and refusal (ModuleGraphError) of a mod x; in a block, a missing file and a non-literal include. The scope tests compare entry matching with a by-hand segment oracle (exact file, directory boundary, sibling sharing a stem), order independence, and the unreadable-diff and non-pull-request cases. Mutating the closure and scope rules fails the new tests, except the impl rule: the generated crates carry no impl headers because that rule over-approximates by design, and the synthetic crate still pins it.

Observability: out of scope for this PR; tracked as #847 using the proposed text. This is the accepted disposition.

@leynos, wait for current-head checks before merging. No further code change is required by this review at 927de20412468ea43d89f0715dfc34776d7567a9.

I applied your retrieved guidance: give each warning a concrete disposition.

Pre-merge verdict

Item Disposition
Testing (Overall) Satisfied by inspection. The child-process tests cover push, schedule, and workflow_dispatch. They assert the output, run heading, and event name against an out-of-scope diff.
Testing (Property / Proof) Addressed. The new tests use independent edge-list and path-segment oracles. They check reachability, ordering, monotonicity, test-only exclusion, unsupported layouts, and conservative event decisions.
Observability Tracked and accepted as follow-up. I verified that open issue #847 contains the proposed requirements and acceptance criteria. Your explicit acceptance gives this warning a concrete disposition. It does not block this PR.
Current-head checks Pending. build-test, netsukefile, and kani-smoke are running. Windows checks, release metadata, and CodeScene are queued.
Review state Still CHANGES_REQUESTED. GitHub reports zero unresolved threads, but the earlier review state remains.

The chain family gives each reference form a case where that reference is the only route to the next module. The generated crates intentionally exclude impl headers. The existing synthetic fixture retains impl coverage. That bounded split is sufficient to address the property-testing warning; do not add another test layer solely to clear this finding.

make test-workflow-contracts includes Hypothesis and discovers both new files through its directory-wide test invocation. The developer-guide addition matches the test design.

I found no new merge-blocking defect in the three changed files. I inspected the code; I did not execute repository tests or independently reproduce the reported mutation results.

Treat this assessment as the current disposition of the stale pre-merge table. The published table still shows the earlier error and warnings.

Before merging:

  1. Wait for the required checks at this exact head.
  2. Clear the earlier review state through the explicit top-level @coderabbitai approve command if you want CodeRabbit approval.

No additional implementation prompt or follow-up issue is needed.

@coderabbitai review. Head 927de20 answers both pre-merge warnings from your review at 6f66257: Hypothesis property tests for the module closure and scope decision, and the observability disposition as issue #847 with a PR comment. Please give your verdict: is anything still blocking merge, including in your pre-merge checks table? If further work is required, please provide an AI agent prompt. Do not treat warnings as optional or aspirational. Where a change is out of scope for this PR, propose a GitHub issue unless one exists already.

@buzzybee-df12, resolve the merge conflicts before merging. At head 927de20412468ea43d89f0715dfc34776d7567a9, I found no further code defect in the changes since 6f662570. GitHub now reports CONFLICTING and merge state DIRTY.

I applied your retrieved guidance: give each warning a concrete disposition.

Pre-merge verdict

Item Current disposition
Testing (Overall) Satisfied. The previously inspected child-process tests cover push, schedule, and workflow_dispatch.
Testing (Property / Proof) Addressed. The new Hypothesis tests use independent graph-reachability and path-segment oracles. They cover ordering, monotonicity, test-only exclusion, unsupported layouts, and conservative proof decisions.
Observability Accepted follow-up in #847. I verified that the issue is open and contains the required changes and acceptance criteria. This warning does not block this PR.
Current-head checks Complete. All reported checks succeeded or were skipped. build-test, kani-smoke, Windows, and CodeScene succeeded. No check remains pending or failed.
Merge conflicts Blocking. Resolve the conflicts against current main, then rerun checks at the resulting head.
Review state Still CHANGES_REQUESTED. There are zero unresolved threads. Request fresh approval after conflict resolution and validation.

The published pre-merge table still shows the old error and two warnings. Use the dispositions above for those findings. This reply does not update the published table automatically.

The incremental change contains two property-test files and the developer-guide update. The chain tests make each reference form the only route to the next module. Keep the existing synthetic fixture for the conservative impl rule; no additional property-test layer is required to clear this finding.

I inspected the code and GitHub results. I did not execute repository tests or reproduce the mutation results.

AI agent prompt: resolve the remaining blocker

Work on leynos/netsuke PR #774, starting from head
927de20412468ea43d89f0715dfc34776d7567a9.

Resolve the merge conflicts against current main. Identify the conflicting
files before editing. Preserve main's dependency and action pins. Preserve
this PR's proof-scope decision, proof-step conditions, required-check
behaviour, nightly schedule, and workflow contracts.

Retain both new Hypothesis test files and the existing regression tests.
Keep observability tracked separately in GitHub issue #847. Do not add the
metrics pipeline to this PR.

Run the workflow-contract suite and required Python formatting, lint, and
type checks in the authorized development environment. Report the conflict
resolutions, commands, results, and any limitations.

After publishing the resolved head, wait for its required GitHub checks.
Do not reuse the green results from 927de204 as validation of the new head.

No additional follow-up issue is needed. After the resulting head passes its checks, post the top-level @coderabbitai approve command to request approval.

leynos added 9 commits October 1, 2026 15:44
`kani-smoke` ran all 15 harnesses on every pull request: 534 runs and
3,696 minutes from 1 to 21 September, although most pull requests change
nothing a proof reads. It is a required check, so a trigger `paths`
filter or a job-level `if:` would leave skipped pull requests
unmergeable.

The job now always runs and reports. After checkout and uv, a new
`Decide Kani proof scope` step runs `scripts/kani_proof_scope.py`, which
diffs the pull request's merge commit against its first parent and
writes `run-proofs`; every later step is conditioned on it. Pushes to
`main`, a new nightly schedule (04:41 UTC) and dispatches always run
every harness, and an unreadable change set runs them too. `build-test`
and `windows` skip the schedule.

The scope lives in `tools/kani/proof-scope.toml`: the harnesses' module
closure plus the toolchain inputs. `kani_proof_scope_test.py`
recomputes the closure from the Rust source, following paths, use
groups, macros, impls and includes, and fails when a harness or a
reached file is outside the scope, or when an entry reaches past it.
The synthetic-crate test pins each closure rule, and the wiring and
decision tests pin the job shape and the script. All 44 mutations in
the proof ledger fail their named test.

ADR-039 records the decision; the developers' guide gains a
"Change-scoped Kani proofs" section.
CodeScene's delta review failed the pull request on three advisory
rules: a complex method and conditional in `read_scope`, the overall
complexity of `rust_module_closure.py`, and a complex method in
`test_scope_reaches_no_further_than_the_closure`.

- `read_scope` delegates each key to `_scope_paths` and the shape
  check to `_is_path_list`, which now requires a list. A scalar string
  such as `sources = "src/ir/"` was previously accepted as a list of
  characters; it is now refused, and a test pins that, together with a
  non-table `scope`.
- The closure's rooted-path, include and ancestor logic move into
  `_path_base`, `_walk_path`, `_include_target`,
  `_declaring_ancestors` and `_all_includes`, with no change in rules.
- The breadth contract is split in two: one test refuses an entry
  covering files outside the closure, the other refuses an entry
  covering nothing in it.
- The synthetic crate gains a `self::` path whose child shares a name
  with a top-level module, so resolving `self::` from the crate root
  now fails the closure test. That mutation survived before.

The mutation ledger is 49 mutations, all killed.
#771's dry-run smoke contract required `ci.yml` to call the Windows
gate with no condition at all, so that every pull request runs the
smoke the release dry run no longer repeats. This branch gives that
call `if: github.event_name != 'schedule'`, because the nightly
schedule exists for the Kani proofs alone.

The contract now admits exactly that condition, compared whole, and
still refuses a missing, null or any other condition. The condition is
true on every pull request, so the guarantee #771 relies on is
unchanged. A push-only condition, a null condition and a disjunct
excluding pull requests each fail the contract. The developers' guide
and ADR-039 say so.
`use crate::tail;` names the module `tail` in a segment that no `::`
follows, so the path walk stopped at the crate root. The file then
reaches `tail` through a bare `tail::` path, which the bare-path rule
sees only among the current module's own children. From a nested
module the crate-root `tail` was therefore missed.

The closure now also resolves each rooted path including its final
segment. When that segment is an item rather than a module, resolution
falls back to the walked prefix, so the rule only over-approximates.
The synthetic crate gains a nested module importing a crate-root module
this way, and dropping the rule fails the closure test.
The child-process tests ran the script only as a pull request, so a
`main` that ignored its event name, or skipped every other event
outright, passed them; only the unit tests of `decide` covered push,
schedule and workflow_dispatch.

`_run_script` now takes the event name. A new case runs the script for
each of those three events on a merge commit that changes only a path
outside the scope, and requires `run-proofs=true`, the "Kani proofs
run" summary and the event named in it. Deciding every event as a pull
request, or skipping every other event, now fails it.
#766 and #768 added five steps to `kani-smoke`: the user manager, the
build standard, cargo-nextest, the scope wrapper's end-to-end suite and
the mutation patch compile gate. Without the decision condition they
would run on a pull request that skips the proofs, and the gate would
then fail outright, because it compiles through the Kani front-end that
only a proof run installs.

- Each of the five steps now carries
  `if: steps.scope.outputs.run-proofs == 'true'`, as every step after
  the decision already did.
- Their inputs join the scope's `infrastructure`: the wrapper suite,
  the mutation evidence test target and its modules, and the patches
  under `docs/verification/mutations/`. A new contract requires every
  file a patch edits to lie in `sources`, since the gate applies each
  patch before compiling.
- `nextest_lane_rules.py` refused any guard on `make
  install-build-tools`. It now allows one only when every suite step in
  the job carries the identical guard, so the install still runs
  whenever the suite does. An unguarded install is unchanged.

ADR-039 and the developers' guide describe both. Mutations K1 to K7
(an unconditioned gate or install, each direction of the guard rule,
each dropped input, a patch outside the scope) are all killed; the
ledger is 62 mutations.
The nextest lane rule compares guards as written and only runs for
jobs with at least one suite step. Record both so a reader does not
mistake the quantifier for a vacuous pass.
The closure and the scope decision control whether the proofs run, so
example-based cases alone left the readers open to an unnamed layout.
Add Hypothesis tests that render small flat crates from an explicit
edge list and check the closure against graph reachability, never a
second parse of the source. They cover every reference form, test-only
exclusion, stability under declaration and line order, monotonicity
when a reference or seed is added, and refusal of unsupported layouts.
A second module checks scope-entry matching by whole segments, order
independence and the unreadable-diff and non-pull-request cases.
Document both in the developers' guide.
Main's recipe_shell now imports shell_word, which the harnesses reach, so
the scope contract failed until the file was listed.

@coderabbitai review. Head 0ef187c is your reviewed 927de20 rebased onto current main. Your verdict there found no code defect. Two things changed: docs/contents.md was merged by hand (both ADR lists kept), and one line adding src/shell_word.rs to tools/kani/proof-scope.toml sources, because main's recipe_shell now imports it and the scope contract failed without it. Please review these and give your verdict: is anything still blocking merge, including in your pre-merge checks table? If further work is required, please provide an AI agent prompt. Do not treat warnings as optional or aspirational.

@wafflecat-df12, no further code change is required by this review at 0ef187c0dbe3898d6efb9a02b68b74f0dc86f247. Clear the outstanding review state before merging.

Changes reviewed

  • docs/contents.md: correct. The merge retains ADR-039 from this PR and ADR-040 and ADR-041 from main. All three link targets exist. Against current main, the index change adds only ADR-039.
  • tools/kani/proof-scope.toml: correct. Keep src/shell_word.rs in sources. src/recipe_shell.rs imports crate::shell_word::ShellDialect. The scoped IR and Ninja modules also reference shell_word. The entry therefore covers a real proof dependency.

Pre-merge verdict

Item Disposition
Testing (Overall) Satisfied. The non-pull-request child-process tests remain unchanged from the reviewed head.
Testing (Property / Proof) Satisfied. Both Hypothesis test files and the synthetic closure regression tests remain unchanged from the reviewed head.
Observability Accepted follow-up in #847. The issue remains open with the agreed requirements and acceptance criteria. This disposition does not block this PR.
Current-head checks Complete. All reported checks succeeded or were skipped. No check remains pending or failed. build-test, kani-smoke, Windows, and CodeScene succeeded.
Merge conflicts Cleared. GitHub reports MERGEABLE.
Review state Outstanding. GitHub still reports CHANGES_REQUESTED and merge state BLOCKED. There are zero unresolved threads.

Use these concrete dispositions for the stale pre-merge table. Do not treat its warnings as optional. The published table still displays the earlier error and warnings; this reply does not update that table.

I found no new merge-blocking code defect in the two changes. No implementation prompt or additional issue is needed. Post the top-level @coderabbitai approve command to request fresh approval.

I inspected repository content and GitHub results. I did not execute repository tests. I used the retrieved guidance that each pre-merge warning requires a concrete disposition.

Comment thread .github/workflows/ci.yml Outdated
Comment thread docs/adr-039-change-scoped-kani-gate.md Outdated
The kani-smoke comment said a pull request skips when it changes nothing
in the scope file; it skips when the changed paths match no entry in the
scope's lists. The ADR inventory omitted src/shell_word.rs and counted
43 files where the closure is now 44, listed as 18 sources entries.

@coderabbitai Head 97e7b8f actions both open threads (ci.yml:376 comment wording; ADR-039 inventory now lists src/shell_word.rs, 44 files in 18 entries). The delta from 0ef187c is docs and comment only. CI is green at this head and no threads are open. Does anything block merging this head?

@leynos, clear the outstanding review state before merging. No further code change is required by this review at 97e7b8f451e4084fddec64397d9d5be40002bd8e.

The GitHub comparison confirms that the delta contains only the workflow comment and ADR-039 documentation changes.

  • The workflow comment now distinguishes changed paths from edits to the scope file itself.
  • ADR-039 now includes src/shell_word.rs and distinguishes 44 closure files from 18 sources entries. The scope file contains 18 entries.
Pre-merge item Current disposition
Testing (Overall) Satisfied; unchanged from the reviewed head.
Testing (Property / Proof) Satisfied; unchanged from the reviewed head.
Observability Accepted follow-up in open issue #847. No implementation is required in this PR.
Current-head checks All reported checks succeeded or were skipped.
Merge conflicts None. GitHub reports MERGEABLE.
Review threads None open.
Review state Outstanding: CHANGES_REQUESTED; merge state BLOCKED.

Use these dispositions for the stale pre-merge table. No finding in that table requires further work in this PR.

Post the top-level @coderabbitai approve command to request fresh approval. This reply does not approve the PR. No AI agent prompt or additional issue is needed.

I inspected the exact delta and GitHub results. I did not run repository tests or recompute the 44-file closure. I used the retrieved guidance on scope-selector counts and concrete warning dispositions.

Learning: In Netsuke, tools/kani/proof-scope.toml sources entries are scope selectors, not a count of files in the Kani module closure. Directory entries can cover multiple files, including test-only files excluded from the closure. Distinguish selector counts, covered-file counts, and computed closure-file counts when reviewing docs/adr-039-change-scoped-kani-gate.md.

Learning: For leynos/netsuke, leynos requires pre-merge warnings to receive a concrete disposition, not treatment as optional or aspirational. Keep in-scope corrective work in the PR. For out-of-scope work, search for an existing GitHub issue and propose a self-contained follow-up issue when none exists. Provide an AI agent prompt when further work is required.
