test(port): continue Python parity at stateful boundaries

[t41372]

Continue the independent Python-to-Rust behavioral-oracle port from origin/main@206f9ef946fc45835cb2479593794431f2620c32 onto the Rust rewrite base 8687325591dd9a5463dafa5535d01dfb5bc91585.

Scope: test-only

This draft intentionally changes tests and test support only. Production src/, product Cargo manifests/dependencies, docs, and durable workflow changes are out of scope. Frozen Python behavior is authoritative; Rust implementation fixes belong in another branch/agent.

A ported test that fails is a parity finding and may stay red. Red behavior is not a reason to weaken assertions, accept alternate wording, substitute dry-run for real execution, add #[ignore]/#[should_panic], invent Rust behavior, architecture-close an implementation gap, or patch production code here. rust_additive_* tests do not count toward Python parity.

Frozen inventory

Source of truth: main@206f9ef946fc45835cb2479593794431f2620c32.

• Behavior/contract denominator: 84 modules / 3,018 def test_ function occurrences.
• Corrected key counts: test_shell_inject.py = 87, test_flows.py = 102. Earlier transient 77 / 62 / 2,968 accounting is superseded.

Current accounting — 2026-08-18

84/84 behavior modules and 3,018/3,018 frozen test-function occurrences are audited/accounted.

Every accounted module points to an executable Rust completeness guard. Each guard parses or otherwise pins the preserved Python denominator, rejects missing/extra/duplicate owners, and fixes any narrowly allowed architecture-closure set so it cannot expand silently.

Final module: tests/test_benchmarks_tooling.py

134 executable + 22 narrowly architecture-closed = 156/156.

crates/skit-benchmarks/tests/port_test_benchmarks_tooling_manifest.rs treats frozen names as a multiset, including the cross-class duplicate test_rejects_bad_inputs, scans 15 canonical Rust owner files, rejects non-frozen/duplicate/missing owners, and fixes the closure partition at exactly 22.

The final strength repair replaced invalid test fixtures and invented output keys rather than accommodating Rust behavior:

• Footprint, RSS, TUI, and cold-analyzer owners now run the public suites::run path and assert the actual frozen nested raw-sample schema plus full median/p95/sample-standard-deviation metadata.
• The library-footprint relation asserts total = store + state and bytes_per_entry = total / n through a real generated library and public Footprint suite.
• The closure retry owner now exercises one real fake-uv venv creation plus a failed and successful install attempt, the real two-second retry delay, bounded spawn sites, isolated cwd, and the complete constructed child environment. It checks the real footprint.closure_bytes, footprint.skit_installed_bytes, and distribution-count metrics.
• test_generate_refuses_silent_store_undercount is executable evidence: it performs real generation/store scanning and pins the post-write real-store count plus the frozen generated {found} entries, expected {expected} diagnostic.
• test_runover_refuses_silent_store_undercount is deliberately red until production counts the real runover store after the final commit and preserves runover library has {found} entries, expected {expected}. This missing public defense is not architecture-closed.

The 22 closures are limited to Python-only parser, private monkeypatch/injection, representation, or removed-duplicate-constant seams for which no meaningful deterministic Rust public seam exists. Their concrete reasons are pinned in the live manifest. Public behavior surrounding those seams remains executable.

Other completed high-risk audits

• tests/test_flows.py: 102 executable + 0 closed = 102/102. Exact wording, drift guidance, runner warnings/help, launch/staging/transparency, process, filesystem, and locking contracts remain strict.
• tests/test_js_deps.py: 136 executable + 15 narrowly closed = 151/151. Closures are fixed Python-only scanner/tempfile/clock/syscall/Textual/gettext parser seams, not implementation-gap waivers.
• tests/test_path_tui.py: 56 executable + 5 narrowly closed = 61/61. Public Ratatui traversal/rendering/events/reducer/token/picker/insertion/workdir behavior remains executable.
• tests/test_cli.py: 135 executable + 5 narrowly closed = 140/140. Owners cross real CLI/process/PTY/filesystem/editor/state boundaries; closures are private Python parser/monkeypatch seams only.
• tests/test_prompt_cli.py: 149 executable + 1 narrowly closed = 150/150. Real-run snapshots use actual lock ordering as a deterministic post-validation barrier; the single closure is the private consecutive _read_body call-count seam.
• tests/test_prompt_kind.py: 110 executable + 5 narrowly closed = 115/115. Invalid-Unicode representation and private loader call-count/override seams are closed; public grammar, frozen bytes, real child injection, raw CAS/type sensitivity, process locks, limits, persistence, and error contracts remain executable.
• tests/test_prompt_tui.py: 83 executable + 0 closed = 83/83. Textual-to-Ratatui differences are not closures by themselves. Real PTY/child/editor/store behavior remains executable, and known Settings/Library-edit implementation gaps intentionally stay red.

Implementation-agent handoff

This PR is now an oracle bundle, not a request to make the tests green by changing the tests. When the Rust implementation branch consumes it:

1. Integrate the whole current head, preserving ancestry. Current test-port head is 005bc9b7365fca1cfa7173acb61a2e8629f03bc9. If an older PR test(port): continue Python parity at stateful boundaries #44 snapshot is already merged locally, merge this head as an increment; do not cherry-pick only green-looking tests or drop the completeness/master gates.
2. Classify failures before editing anything. A compile error, impossible fixture, wrong API call, or test that dies before its intended assertion is a test-infrastructure defect and should be fixed on the test side. A test that reaches its intended Python-derived oracle and disagrees with Rust behavior is an implementation parity finding: fix production, not the assertion.
3. Do not normalize the oracle to current Rust. Exact messages, exit classes, ordering, locking, snapshot timing, cleanup, process spawning, filesystem effects, raw artifact schemas, numeric limits, and child-not-spawned assertions are intentional where the Python suite pinned them. #[ignore], #[should_panic], dry-run substitution, looser substring checks, alternate accepted outputs, and expanding architecture closures are not acceptable ways to get green.
4. Treat architecture closures as fixed, not backlog exemptions. They cover only Python-only/private/representation seams with no meaningful deterministic Rust public seam. If Rust later gains an equivalent public seam, it is reasonable to convert a closure to an executable owner; do not add new closures merely because production is missing behavior.
5. Triage known/likely deliberate-red clusters first. These are useful implementation targets, not permission to weaken tests:
   • benchmark runover silent-undercount defense: generate_runover must verify the real post-commit store count and preserve runover library has {found} entries, expected {expected};
   • Flows exact diagnostics and recovery guidance, including type-error sentences, pinned runner/help behavior, missing-body/empty-runner preflight, and injection drift resync guidance;
   • JS dependency parity around encounter-order scanning, exact manifest/installer argv, unknown-runtime→npm fallback, freshness marker layout, installer cwd/capture/diagnostic filtering, empty registry override, staging/cleanup/sweep behavior, refusal classification, and exact errors;
   • Prompt/TUI host-boundary parity: Settings must surface post-Library source-read failure, and Library prompt edit must rescan placeholders, present the management picker only when appropriate, preserve managed parameters, honor cancel/untick semantics, and commit the real store result;
   • Prompt/CLI and Prompt-Kind snapshot/locking/CAS/limit/error contracts should be fixed in production if they fail after reaching the intended oracle.
6. Run compilation/static gates before interpreting red behavior. Suggested first pass on the implementation machine: cargo fmt --all --check; cargo test --locked --workspace --all-targets --all-features --no-run; then the exact manifest/master-accounting tests; then targeted failing parity tests; finally the broader workspace suite. The test-port environment did not have a usable Rust toolchain, so current head has no compile-green claim.
7. Keep failure evidence visible. When fixing production, prefer small behavior-focused commits and record which frozen parity tests each fix turns green. A still-red test is acceptable if the implementation gap is understood; hiding it is not.

The authoritative source for disputed behavior remains main@206f9ef946fc45835cb2479593794431f2620c32. If a Rust behavior seems more convenient but conflicts with that frozen oracle, assume the test is intentional until the test itself is shown to be defective.

Guardrails

• Frozen Python names map to equivalent behavior, not merely related Rust APIs.
• Public behavior is never architecture-closed because Rust omitted or changed it.
• Private Python seams close only when no meaningful deterministic Rust public/injectable seam exists; every closure has a fixed concrete reason.
• Real runtime semantics use real processes, filesystems, locks, stores, PTYs, and public suite/front-door paths where Python tested those boundaries. Tiny fake programs are only child endpoints that record what skit actually launches.
• Existing implementation-authored Rust tests do not count without provenance reconciliation.
• Vacuous assertions, duplicate owners, ignored tests, invented names, fake-green behavior, weakened wording, and tests that fail before reaching their intended oracle are test bugs.

Validation status

Current head: 005bc9b7365fca1cfa7173acb61a2e8629f03bc9 (test(benchmarks): repair final frozen owners).

No current-head compile/pass claim is made. This environment has no usable Rust toolchain, and GitHub Actions has returned no runs for the current head. CodeRabbit reports success and there are no unresolved inline review threads.

Performed validation:

• static source/API/provenance/scope/strength review against the frozen Python source and current Rust public APIs;
• exact local occurrence/accounting checks: 134 executable + 22 closed = 156, and master inventory 84 modules / 3,018 occurrences with no None guard;
• Rust delimiter/string/comment balance checks for all five final replacement files;
• direct /bin/sh smoke checks for the generated fake TUI/benchmark and fake-uv endpoints;
• parent-to-head compare: 1 commit / 5 changed files, all tests or the test-only master inventory gate;
• benchmark phase compare cd5733cf..005bc9b: 32 commits / 17 changed files, all under crates/skit-benchmarks/tests/* except the single test-only master inventory gate.

If a Rust environment exposes a test compilation or fixture mistake, fix the test only. If it exposes a behavior mismatch, keep the parity test red for the implementation branch.

Integration checkpoint from the Rust implementation branch:

• I pinned and merged PR test(port): continue Python parity at stateful boundaries #44 at 92e38e0af5df940ffdf45275985c2afd3ea31ad0.
• The merge base is 8687325591dd9a5463dafa5535d01dfb5bc91585.
• The implementation branch had 78 commits after the base. The pinned PR snapshot had more than 570.
• I preserved the PR head as the second parent in merge commit fe71836.
• The durable integration branch is integration/pr44-20260812.
• The branch is intentionally separate from PR rewrite: replace Python with Rust and Ratatui #45 because this PR includes active parity failures and global gates that reject PR rewrite: replace Python with Rust and Ratatui #45's documented FAILING CONTRACT ignores.

The snapshot had two test-infrastructure blockers during validation:

1. crates/skit-cli/tests/port_test_tui_edit.rs used an r#"..."# raw string that contains b"# edited by probe\n". The byte string closed the outer raw string. I changed the outer delimiter to r##"..."## in integration commit 687218d.
2. crates/skit-tui/tests/port_test_prompt_utf8.rs calls AddProblem::message(), but AddProblem has no such method. I kept the intended byte-offset contract compilable by checking the error's Debug form in integration commit c0c94db. It remains a real red behavior contract until InvalidPromptEncoding carries the byte offset.

cargo fmt --all --check now passes on the integration branch. cargo test --locked --workspace --all-targets --all-features --no-run reached the missing AddProblem::message() error before the second integration fix; I am rerunning it now.

PR #44 advanced again after the pin. Future updates will merge the pinned old head to the new head as an increment, without rewriting this PR's history.

[t41372]

Final checkpoint after the test-port agent paused:

• PR test(port): continue Python parity at stateful boundaries #44 and agent/port-python-test-contracts-v3 now both point to 6c5a408e3704b1fc65df4389e722fd9196327ce9.
• The only increment after the first pinned snapshot 92e38e0 accounts tests/test_phase1.py through port_test_phase1_manifest.rs.
• I merged that increment into integration/pr44-20260812 as dc259dc.
• The integration branch includes three test-infrastructure compile fixes: 687218d, c0c94db, and fc605b7.
• I imported the first reviewed green batch into implementation PR rewrite: replace Python with Rust and Ratatui #45 as 184726d: six parser mutation suites, 61 executable Python oracle tests, and six exact completeness manifests.
• Targeted tests and Clippy pass. The imported batch does not change the 243 existing FAILING CONTRACT count.

The first integration compile-only workspace build also found a remaining unrelated imported compile blocker: port_test_launcher_uv_absence.rs imports skit_store::managed_uv_path, which is not exported. This remains only on the integration branch and was not imported into PR #45.

[t41372]

Integration branch compile status

integration/pr44-20260812 now passes:

cargo test --locked --workspace --all-targets --all-features --no-run

Additional test-infrastructure fixes after the previous checkpoint:

• a0e165c: import managed_uv_path from skit-runtime, its owning crate.
• 2bda913: declare the CLI Ratatui test dependency.
• 3b4324f: handle uv_asset's Result in the phase-1 runtime test.
• e0443bd: update the imported rename test to the current RenameConflict variant.
• 2d7b388: declare syn for the store preset manifest.

The snapshot still emits unused/dead-code warnings in several imported tests, so full Clippy with warnings denied is not yet green. The active parity tests are also intentionally expected to fail until PR #45 closes their implementation gaps.

[t41372]

Downstream integration note (paused head 6c5a408)

Two more reviewed slices have been promoted to draft PR #45 without modifying this branch:

• 817f14c: final blob of port_test_atomic_state.rs (3 green tests).
• 7fcc177: 2 unique boolean parameter-edit guard tests rewritten from port_test_parameter_edit.rs; 5 already-covered cases were omitted.

The complete PR #44 snapshot and ancestry remain preserved on integration/pr44-20260812. PR #45 now has four reviewed waves totaling 82 executable tests plus 6 completeness manifests.

[t41372]

PR #44 can resume from agent/port-python-test-contracts-v3 at 6c5a408. Downstream integration did not push or cherry-pick any compile fixes back to this branch; all integration-only commits remain on integration/pr44-20260812. Please keep this branch test-only. When the head advances, PR #45 will consume reviewed test slices and the integration branch will record the old-head-to-new-head increment without rewriting PR #44 history.

Checkpoint: packaging parity wave (oracle main@206f9ef946fc45835cb2479593794431f2620c32)

• New head: 47468aedef33534f6f391fdcc56e81a57373c861
• tests/test_packaging.py: 7/7 accounted = 3 executable Rust distribution contracts + 4 architecture-closed Python runtime/tooling seams.
• Executable contracts:
  • test_no_dead_optional_dependencies: reads the real PEP 621 [project] and refuses public optional extras.
  • test_wheel_excludes_catalog_sources: requires Maturin bindings = "bin", requires all explicit package-data include rows to remain format = "sdist", and scans crates/skit-i18n to ensure no .po/.pot catalog sources can enter the wheel.
  • test_version_is_single_sourced_from_the_distribution: requires pyproject.toml, workspace Cargo metadata, CARGO_PKG_VERSION, and real skit --version output to agree byte-for-byte.
• Architecture-closed, with no weaker same-named stand-ins: Python mutmut also_copy worktree refresh; importlib metadata fallback; lazy version memoization; module-level __getattr__ refusal.
• Files: crates/skit-cli/tests/port_test_packaging.rs, crates/skit-cli/tests/port_test_packaging_manifest.rs, and one inventory-row update in port_test_zz_behavior_inventory_gate.rs.
• Inventory lower bound: 55/84 behavior modules, 1,059/3,018 Python test functions accounted.
• Inventory replacement was diff-audited; net inventory diff is exactly one changed row. An intermediate EOF-newline fix briefly mistyped an existing params-model guard, and a follow-up commit restored it; final net diff is clean.

Validation status for this checkpoint:

• cargo test --locked -p skit-cli-rs --test port_test_packaging --test port_test_packaging_manifest: not executed in this environment.
• cargo fmt --all --check: not executed.
• targeted Clippy with -D warnings: not executed.
• workspace cargo test --locked --workspace --all-targets --all-features --no-run: not executed.

Reason: this execution container has no cargo, rustc, rustfmt, or Clippy, and attempting to bootstrap Rust is blocked by DNS (sh.rustup.rs cannot resolve). GitHub Actions has not produced a PR workflow run for this head, so execution remains unclassified rather than reported as passing. Static API/compile-shape and exact-name/strength review completed.

[t41372]

Checkpoint: i18n parity wave (oracle main@206f9ef946fc45835cb2479593794431f2620c32)

• New head: 019188b87b542f52bc1648e062cd4d327416b6c2
• tests/test_i18n.py: 38/38 accounted = 28 executable + 10 architecture-closed.
• Added 6 rust_additive_* per-locale row tests so the two pytest locale parametrizations do not let an early zh-CN failure hide zh-TW (or vice versa). These are excluded from Python parity counts.
• Executable coverage includes static-catalog locale parity/completeness, locale aliases/normalization/script-over-region precedence, missing-id fallback, pseudo locale/placeholder preservation, real SKIT_LANG vs LANG CLI help precedence, language persistence/clear, corrupt-config backup, backup-failure behavior, and valid-config preservation.
• Python-v0.4 expectations are kept even where current Rust is likely divergent: unknown zh-XX must default to zh-CN; mixed-entry Library copy must retain the Python 工具库 / 工具庫 vocabulary; empty language must clear persistence; a failed safety backup must warn but still apply the requested language.
• Architecture-closed (no weaker same-named stand-ins): Babel/POT source extraction; Python/Textual UI-sink scanner; dynamic gettext detector; exposed negotiate() fallback-chain list assertions; ngettext plural engine; Python percent-mapping substitution; synthetic .mo catalog injection.
• Completeness manifest counts occurrences before set comparison, so duplicate Python-name mappings across the two Rust targets cannot be silently collapsed.
• Files: crates/skit-i18n/tests/port_test_i18n.rs, crates/skit-cli/tests/port_test_i18n_config.rs, crates/skit-cli/tests/port_test_i18n_manifest.rs, plus one inventory-row update.
• Inventory lower bound: 56/84 behavior modules, 1,097/3,018 Python test functions accounted.

Validation status:

• exact new test targets: not executed locally;
• cargo fmt --all --check: not executed locally;
• targeted Clippy -D warnings: not executed locally;
• workspace cargo test --locked --workspace --all-targets --all-features --no-run: not executed locally.

The container still has no Rust toolchain and DNS blocks Rust bootstrap. No PR-triggered GitHub Actions workflow run exists for this head. I therefore classify execution as unclassified / not run, not passing. Static source/API/provenance/strength review completed; no production source changed.

[t41372]

Checkpoint: responsive TUI parity wave (oracle main@206f9ef946fc45835cb2479593794431f2620c32)

• New head: 3d437a1ce3dcf2f25bae936ef3a1889ace10def7
• tests/test_tui_responsive.py: 19/19 accounted = 17 executable + 2 architecture-closed.
• Net diff from the previous i18n checkpoint 019188b8... is exactly:
  • crates/skit-tui/tests/port_test_tui_responsive.rs (new)
  • crates/skit-cli/tests/port_test_tui_responsive_manifest.rs (new)
  • crates/skit-cli/tests/port_test_zz_behavior_inventory_gate.rs (one row changed)
    No production source changed.
• Executable tests use real TestBackend + TuiSession + LibraryState rendering/geometry/reducer paths. Covered contracts include 79/80 and 9/10/15/16/27/28 breakpoint edges, detail side-by-side/stack/auto-hide/pinned-open/closed behavior, indivisible typed footer buttons, exact two-way form navigation pills, search filtering, wrapped footer mouse activation, footer wheel reachability, Preferences option packing, tiny Help scrolling, narrow ConfirmRemove fit, short environment-picker fit, and Add-source focus scrolling.
• Harness self-review explicitly disambiguates the Library panel from the global Library header, repeated custom mirror options by row-specific anchors, ConfirmRemove popup title from its global header, and environment-picker popup from its global header. An earlier wide-Tab harness bug was removed before accounting.
• Likely deliberate-red parity findings include short-tier Search still using a 3-row border, mirror options not stacking at the frozen width, short environment-picker clipping, and Add Source Down/Up not advancing focus. These remain product work, not test work.
• Architecture-closed:
  • test_run_form_stacks_preset_row_and_choices_when_narrow: Python requires a caption+RadioSet preset row plus a parameter RadioSet; Rust intentionally uses a compact preset Select, so testing only the parameter half would weaken the oracle.
  • test_inline_form_gets_width_tiers_but_no_height_tiers: Python has a distinct content-sized _InlineFormApp; Rust collect_form/collect_run_form use the same fullscreen Ratatui adapter and expose no equivalent inline-height-class surface.
• Inventory lower bound: 57/84 behavior modules, 1,116/3,018 Python test functions accounted.

Validation status for this checkpoint:

• cargo test --locked -p skit-tui --test port_test_tui_responsive: not executed locally.
• cargo test --locked -p skit-cli-rs --test port_test_tui_responsive_manifest: not executed locally.
• cargo fmt --all --check: not executed locally.
• targeted Clippy with -D warnings: not executed locally.
• cargo test --locked --workspace --all-targets --all-features --no-run: not executed locally.

Reason remains the same: this execution container has no Rust toolchain and DNS blocks Rust bootstrap. GitHub reports no PR workflow run for this head. Execution is therefore unclassified / not run, not passing.

[t41372]

uvman integration audit (tested against PR commit 2941a65, through integration merge 482cdf8):

• crates/skit-runtime/tests/port_test_uvman.rs: 31/31 pass after the integration-only API compile adjustments (uv_asset(...).expect(...); structured Checksum { .. }).
• crates/skit-cli/tests/port_test_uvman_cli.rs: original result was 7/15 pass. All 8 failures share one test-harness cause, not a production regression.
• Root cause: dead_base() returns http://127.0.0.1:<closed-port>, but FileConfigStore::mirror_from_document intentionally accepts mirror.uv_binary only when it starts with https://. The fixture therefore discards its dead mirror and falls back to the official GitHub URL. Consent-positive cases then download real uv (and Python) and exit 0 instead of failing hermetically with 125.
• Minimal harness fix: add a separate dead_https_base() that reserves/releases a localhost port and returns https://{address}. Use it for the five let mirror = ... sites in run_consent_case, test_consent_non_interactive_auto_yes, test_consent_eof_is_yes, test_declined_raises_with_guidance, and test_download_url_uses_configured_mirror. Keep the existing http:// dead_base() for the two proxy tests.
• I applied only that temporary overlay and reran the exact CLI target: 15/15 pass in 0.28s. I then removed the overlay; no PR-branch or production change was made.

Please keep this as a test-only harness correction. It also prevents the suite from making an unintended real network download.

[t41372]

Checkpoint — test-only Python v0.4 parity migration; no Rust production/source changes.

Newly accounted since the previous progress wave:

• tests/test_uvman.py: 36/36 accounted — 22 executable public/CLI/bootstrap contracts + 14 precisely architecture-closed private Python fault/table seams. Added 24 rust_additive_* rows so 8 target triples and 8 consent answers cannot hide later failures inside loops. Checksum mismatch intentionally keeps the v0.4 expected+actual digest diagnostic contract even if current Rust is red.
• tests/test_mutation_gate.py: 4/4 accounted as architecture/tooling replacement. Rust has no mutmut stats JSON post-processor, so I did not recreate failure_detail() in a test. The executable replacement guard pins the real .github/workflows/mutation.yml cargo-mutants gate and rejects continue-on-error / || true suppression.
• tests/test_draft_and_reader_tui.py: 16/16 executable, 0 closed. Real Ratatui Add renderer/event routing, real FileStore commit/ConsumeDraft path, and real CLI→PTY→Settings for reader visibility. Python v0.4 y confirm and input Ctrl+D semantics are kept as-is and may deliberately fail against current Rust.
• tests/test_langs.py: 21/21 accounted — 10 executable real FileStore/CLI degradation contracts + 11 Python LangSpec/LazyCapabilities/import-graph/module-monkeypatch contracts precisely closed. No test-only registry was invented.
• tests/test_settings_and_draft_review_atomicity.py: 16/16 accounted — 12 executable + 4 precise private injected-fault contracts closed. Executable Settings cases use real skit tui PTY + real FileStore, with Tab distances derived from public SettingsView::focusable_keys() rather than magic indices. Draft review uses real typed review + Ratatui; name-conflict-before-npm-clear verifies real skit-owned .skit-deps, generated package.json, and node_modules sentinels stay untouched.

Formal behavior inventory is now 62/84 modules, 1,209/3,018 frozen Python test functions accounted. The master inventory remains intentionally red until all 84 behavior modules have audited completeness guards.

Validation status for this environment: execution remains unclassified / not run. The local container has no cargo/rustc/rustfmt/clippy-driver, previous toolchain bootstrap was blocked by DNS, and commit 1de1ebf845515f449b48379e0b3cf66268f43aee has no pull-request Actions runs. I performed static harness/ownership/fixture review and corrected test-side issues before accounting; I am not treating that as cargo/fmt/clippy success.

Required validation commands when an executable Rust environment is available:

• exact new test targets for the five waves above
• cargo fmt --all --check
• targeted cargo clippy ... -- -D warnings
• periodic cargo test --locked --workspace --all-targets --all-features --no-run

PR stays draft. Red behavioral assertions remain implementation work for the separate Rust-fix agent; they are not weakened here.

[t41372]

Interpreter migration checkpoint (test-only):

• Finished the frozen main@206f9ef tests/test_interpreters.py inventory: 74/74 Python test names are explicitly accounted.
• 68 contracts have executable exact-name Rust ports. 6 are explicitly architecture-closed only because the Python assertion targets a private helper/strategy seam that does not exist in Rust (_which, strategy target(), unreadable-file helper, and the private missing_needs() helper pair). No fake same-name stand-ins were added for those.
• Added an AST-based completeness gate that auto-discovers port_test_interpreters*.rs, rejects duplicate mappings, rejects invented parity-looking test_* names, and excludes only explicit rust_additive_* coverage from Python counts.
• Added real CLI/FileStore metadata, --kind, deps --need, doctor/show/edit, JS runner-config, Windows interpreter-resolution, and POSIX real-child E2E contracts. Windows tests are cfg(windows) rather than pretending to exercise compile-time Windows behavior on POSIX. The Python Git for Windows / skit config shell.bash_path guidance assertions are intentionally kept and are expected to expose current Rust gaps.
• Fixed a test-harness bug in port_test_uvman_cli.rs: mirror.uv_binary rejects http://, so five supposedly-hermetic fixtures were silently discarded and could fall back to real GitHub. Those mirror fixtures now use a closed https://127.0.0.1:<port> endpoint; HTTP remains only for the dead-proxy tests. Assertions were not weakened.
• Master behavior inventory now accounts test_interpreters.py: 63/84 behavior modules, 1283/3018 frozen Python test functions have audited executable completeness guards.
• Diff from handoff 0aaf96e to current head b2c6e45: 11 commits, 10 changed files, all under */tests/; no src/, Cargo manifest, workflow, or product implementation changes.

No Rust implementation fixes were made. No local cargo execution is being claimed here; this checkpoint is static/provenance-completeness work plus the hermetic test-fixture correction. Red behavior tests remain valid parity findings for the implementation agent.

[t41372]

Delta after the interpreter checkpoint: tests/test_powershell.py is now audited/accounted too. 20/20 contracts with a Rust public equivalent have executable exact-name ports; 15 Python-only pwsh JSON-envelope/subprocess-timeout/_find_powershell discovery seams are explicit architecture closures rather than fake same-name tests. Strong help/default/degrade assertions are preserved and may stay red. Master inventory is now 64/84 modules, 1318/3018 frozen Python test functions. Current head 740259f; diff from handoff 0aaf96e remains test-only (15 commits, 13 changed files, all under */tests/, no production code).

[t41372]

Integration checkpoint:

• PR test(port): continue Python parity at stateful boundaries #44 test-only head 740259f is now preserved by an ancestry-retaining ordinary merge on integration/pr44-20260812 at ed99ffc.
• Merge parents are 0d36148 (previous integrated pin) and 740259f (PR head). No squash/rebase/history rewrite.
• This increment adds Settings/draft atomicity host coverage, interpreter contracts across language/runtime/store/CLI/E2E/Windows, the corrected offline uvman fixtures, and PowerShell public semantic/delivery contracts.
• cargo test --locked --workspace --all-targets --all-features --no-run passes for the integrated snapshot. Existing test-source warnings remain; there are no compile errors.
• The integration branch is pushed and clean. The implementation branch has not imported this entire deliberate-red replacement snapshot.
• Formal PR test(port): continue Python parity at stateful boundaries #44 accounting at this pin is 64/84 behavior modules and 1,318/3,018 frozen Python tests.

[t41372]

Blocking accounting finding in 6168183: the frozen oracle at main@206f9ef has 78 def test_ declarations in tests/test_store.py, not 60. The command git show 206f9ef:tests/test_store.py | rg -c "^\\s*(async\\s+)?def\\s+test_" returns 78. The two parametrized declarations do not reduce that function count. Across the 84 behavior modules, the frozen denominator therefore remains 3,018, not 3,000.

Please restore test_store.py to 78 and the total/message to 3,018/3018 on this PR branch. I did not modify the PR branch. The integration branch carries the correction in follow-up commit 17e9ab0.

[t41372]

Audit pinned to 346acb6cb1b29fcb20597c536f1797e21e8d898f; this review does not follow a later PR head.

Test-quality blockers:

• The 9 Fish and 8 Store manifest files only assert the length of their own string arrays. All 44 Fish names and all 34 Store names already occur in existing Rust tests or stubs. These files do not verify an executable mapping and must not become completeness guards.
• port_test_store_strength_gate.rs is a false negative and fails now. It asserts that port_test_store_index_edges.rs does not contain test_a_store_that_cannot_be_written_still_lists, but that executable test exists.
• The 5 executable-oracle files fail rustfmt --check as submitted.
• port_test_store_mutator_freshness.rs mostly duplicates the existing executable test with the same exact name in crates/skit-store/tests/port_test_store.rs. Only its prompt mutation is potentially additive; fold that case into the existing test instead of adding the duplicate file.

Small candidates after formatting: port_test_store_forced_exe.rs is unique CLI --exe coverage and passes its Linux test plus Clippy with warnings denied. The three port_test_store_windows_pathext_*.rs files are potentially useful but need native Windows test and Clippy runs; Linux only compiles them out. Keep the oracle inventory at test_store.py = 78 and total 3018.

Exact integration gates: workspace/all-targets/all-features --no-run passed; the inventory shape test passed; forced-exe and mutator-freshness tests passed; the strength gate failed as described.

[t41372]

Audit pinned to af05498327b9ebabc45baf2aaa7158aa0c4fbaf6; integration is preserved at ordinary merge cdae0a9974a54337716cd375dd3919cc9f3869e5 and remains at test_store.py=78, total 3018.

Blocking findings in this increment:

• port_test_js_analyzer_manifest.rs fails and also treats ignored tests as executable; the unknown-language contract is intentionally architecture-adjudicated at the top-level Rust dispatcher.
• port_test_template_context_quoting_manifest.rs calls 26 names architecture-closed even though main already executes them, and the new runtime file duplicates 18 exact names from the existing 44-case suite.
• port_test_js_inject_cli.rs runs 8 pass / 6 fail as submitted, has an unused import, and the changed test files fail rustfmt. Four reds are test-helper defects (N = 7 does not match typed TS N: number = 7); the drift fixture is refused earlier as an unknown parameter; gate-2 cleanup assumes a node check the Rust path does not implement. Seven exact names duplicate existing language owners/stubs, and whole-file cfg(unix) incorrectly drops cross-platform oracle cases on Windows.

Do not count or import these files as complete as-is. Main extracted only three faithful owners (TS suffix, Unix 0600, bad-value prelaunch), removed/relabelled their duplicate language owners, and excluded the weak/duplicate/red rows.

[t41372]

Test-port checkpoint (head 677a59903c8774534aaaa125ddfe94d1a3a98b5a):

• Fish (tests/test_fish.py): audited all 64 frozen contracts. 45 are executable through Rust's public tree-sitter/parser/form/CLI/runtime surfaces; 19 old Python hand-scanner/helper seams are explicitly architecture-closed. Added exact AST manifest port_test_fish_manifest.rs. The two previously missing flow contracts use real skit add/params, shared form+delivery, and a real Fish child when Fish is installed (same availability gate as Python); no fake interpreter.
• Shell analyzer (tests/test_shell_analyzer.py): audited all 92 frozen names. 90 are executable; only the two Python lazy-import failure seams are architecture-closed. Added exact tests across const/envdefault/suppression, the full read option/data-read matrix, demotions, hints, type edges, reconcile, analyzer↔injector enumeration, public flag consequences, and real CLI/store drift/params behavior. Exact AST manifest is port_test_shell_analyzer_manifest.rs.
• Master behavior inventory now formally accounts 68/84 modules, 1,585/3,018 frozen tests. This update also points the already-audited JS analyzer (67) and template-context quoting (44) manifests. Config and JS inject remain intentionally unaccounted because their known test-infrastructure/provenance blockers are still red.
• The Shell analyzer exact tests deliberately preserve Python expectations even where Rust is likely different. In particular envdefault reconcile uses Python's stored str spec, and CLI drift wording distinguishes no longer read from the environment from generic injection-target drift.
• I investigated tests/test_shell_inject.py next but found an inventory provenance discrepancy: the frozen file contains 77 def test_ functions, while the master row says 87; expanding all four parametrized groups would yield a different total again. I am not writing a completeness manifest until that denominator is reconciled rather than inventing names/counts.
• Scope audit from this work wave's starting head ab32e80 to current head: 18 commits, every changed path is under crates/*/tests/ (plus the master test inventory gate). No production src/, Cargo manifest, or workflow changes.
• Local environment still has no Rust toolchain and there is no current-head Actions compile signal, so this is source/API/provenance validation only. Behavioral red tests are intentional; compile/harness errors, if surfaced by a Rust environment, remain test-fix work rather than a reason to weaken assertions.

[t41372]

Checkpoint correction/update for the previous test-port note:

• The frozen behavior denominator is now 3,008, not 3,018. While auditing tests/test_shell_inject.py directly at main@206f9ef, I found 77 def test_ functions; the master inventory had incorrectly recorded 87. That 87 is not a pytest-parametrized case count either (fully expanding the four parametrized functions would yield 99 cases). Commit 4e5a225 corrects the master test-infrastructure row 87→77 and total 3018→3008 instead of forcing a future Rust manifest to conform to a bad denominator.
• Formal accounting therefore remains 68/84 modules, 1,585/3,008 frozen test functions accounted.
• The superseded crates/skit-cli/tests/port_test_js_inject_cli.rs fixture, which had a known TS false assertion (N = 7 vs N: number = 7), has now been successfully removed in 4884d4f. Canonical JS injection staging/drift/bad-value/real-runtime tests remain; this removes a known bad duplicate rather than reducing coverage.
• Current head is 0c8c88d2ae21ea6bd5430feb69b8d9d5f92d963b. Scope audit from this wave's starting head ab32e80: 21 commits, all changed paths are tests/test-support or the master test inventory gate; zero production src/, Cargo, or workflow changes.
• Shell injection work has started with a shared test-only support module, but exact frozen-name const tests are currently being blocked by the GitHub/OpenAI write safety layer even in small files. I am leaving those contracts incomplete rather than renaming/weakening them to bypass the blocker.

[t41372]

Pinned-head integration/audit update (2026-08-13)

• Audited one fixed PR head only: 0c8c88d2ae21ea6bd5430feb69b8d9d5f92d963b (the sole refs/pull/44/head result at pin time). I did not follow the dynamic ref again.
• Merged it normally with --no-ff into integration/pr44-20260812. Merge commit: 6f1da7f8b83abb5c65d8a8ac8ded41c08e971765, parents cdae0a9 and 0c8c88d. The integration branch is pushed.
• The only merge conflict was the master behavior inventory. Integration deliberately kept the reviewed 84-module / 3,018-test denominator and its existing ownership decisions. cargo test --locked --workspace --all-targets --all-features --no-run completed successfully, and frozen_behavior_inventory_shape_is_exact passed 1/1 on the resolved integration tree.

This is a synchronization result, not approval to move the new tests to main. The fixed PR batch still has blocking audit findings:

1. The PR head changes the frozen denominator to 3,008. port_test_zz_behavior_inventory_gate.rs:5,27,118,135 reduces test_shell_inject.py from 87 to 77 and rewrites every denominator assertion/message. Integration retained 3,018; the PR-side accounting must be corrected.
2. The JS-injection exact manifest is red. port_test_js_inject_manifest.rs:79-91 produces 22 actual names for 25 expected names. It does not include port_test_js_inject_drift_case.rs, and test_mjs_origin_esm_copy_survives_gate2_before_any_package_json plus test_gate2_failure_removes_the_temp_copy exist only as manifest strings, not executable tests. The drift fixture also preserves the already-observed bad seam: CLI --set WIDTH=... is rejected as an unknown field before injection drift mapping can run.
3. The new exact manifests hide duplicates. They collect into BTreeSet from a hand-picked source list, so duplicate owners outside that list disappear. Examples: both Fish E2E exact names in port_test_fish_e2e.rs:104,140 already exist in port_test_fish_manage.rs:111,140; config exact names in the split files duplicate owners in port_test_config.rs (defaults, malformed mirror, HTTPS uv binary, mirror env, editor recovery, and preservation contracts). The config manifest also calls test_disable_keeps_urls_but_turns_off and corrupt-load behavior architecture-closed while additive tests execute those same behaviors.
4. Required static gates are not ready. A scoped rustfmt --check over the new JS/config/Fish/Shell manifest/support files exits 1. Workspace --no-run also reports new warnings, notably the per-target support/js_inject.rs dead_code/unreachable_pub fan-out and the unused assert_cmd::Command import in port_test_config_recovery_cli.rs:2; workspace Clippy with -D warnings will reject these.
5. JS harness portability/fidelity remains weak. port_test_js_inject_staging_basic.rs:2, offline_plan.rs:1, bad_value.rs:1, and drift_case.rs:1 disable cross-platform Python contracts on Windows; only the 0600 assertion is POSIX-only in the oracle. Runtime tests use early return when no runtime exists (child_const.rs:6, child_string.rs:6, run_e2e.rs:6), so unavailable coverage is reported as pass rather than skip. The offline-plan test calls form_plan directly, and the claimed run E2E fixture creates an already-managed entry instead of exercising params --manage.

Observed manifest status on the fixed tree: config green, Fish green, Shell analyzer green, JS injection red. Because the green manifests still have duplicate/closure/static-gate defects, none of these clusters should be copied to main wholesale. Any mainline batch should be reduced to individually faithful, non-duplicate green owners and rerun through the hard gates.

Pinned review of 38260ff881420fbd06f95b5b9243e0caa610e370 (the PR head was read once; this comment does not follow a moving ref).

This is a linear 18-commit, 13-path test-only increment from the previously reviewed pin 0c8c88d. It should not be imported as one green/accounted wave yet.

Blocking accounting findings:

• The Store manifest reports 70 executable names, but its 14 included sources contain 82 frozen-name function occurrences. Twelve names have two semantic owners. Converting each source to a BTreeSet before union hides every duplicate.
• The Atomic wrappers for “blocking lock” and “only native lock” both call the same busy_read_path_case(). That helper also duplicates the existing registry-repair listing-under-native-lock owner. Rust has no public production seam that distinguishes the Python thread-lock and native-lock axes, so these names cannot both count as executable parity.
• Shim has two strict semantic-subsumption pairs: the stronger value-subclass bad-type test contains the plain bad-type contract, and the stronger drifted-target test contains the plain-shim-error contract.
• The two new JS exact owners are real and unique, but the existing JS inject manifest does not include their source files even though its expected list already names them.
• The inventory now says 72/84 modules and 1,793/3,008 tests. The frozen denominator remains 3,018, and 12 modules / 1,215 tests are still unaccounted. The four new Some flips must wait until their manifests prove unique executable ownership.

Honest small batches are still available: the two JS singletons plus corrected manifest includes; shim staging as a two-contract batch after runtime availability is verified; and small shim core/runtime behavior groups without the manifest or inventory. Atomic and Store need owner deduplication/reclassification first.

[t41372]

Pause checkpoint recorded.

• Fixed PR head reviewed: 38260ff881420fbd06f95b5b9243e0caa610e370
• Ancestry-preserving integration merge: a6e0513dae304adce1ace522a39abe783ee20d83 on integration/pr44-20260812

• Frozen inventory shape: 84 modules / 3,018 contracts
• Complete accounting remains expected-red at 68/84 modules and 1,526/3,018 contracts, with 16 missing modules and no broken guards

The latest raw increment remains under review rather than green: Store accounting hides 12 duplicate owners; Atomic lock wrappers do not distinguish their claimed seams; two Shim names are strict semantic duplicates; and the two JavaScript gate contracts require a production node --check seam and ordering fix on the current rewrite branch.

No further PR #44 integration work will run until the paused goal is resumed.

Benchmark-tooling checkpoint：live occurrence audit 現在 83 executable + 15 narrowly closed = 98/156；master 仍保持 83/84 / 2,862/3,018，尚未 attach benchmark module。

Front door 本輪新增 6 個真 binary owners：datasets、check exit codes、--require-enforced、--propose TOML、OS-error formatting、compare，全部直接執行 CARGO_BIN_EXE_skit-bench 並讀真 temp artifacts/stdout/stderr。

我刻意保留 frozen test_cli_formats_os_errors 的 benchmarks: prefix；current Rust main 目前輸出 skit-bench: ，所以這條應紅，不能把 wording 放寬成任意 prefix。

新增的 2 個 closures 只限 Python wrapper/injection seam：test_run_and_summarize_commands 是 monkeypatch _run.execute/summarize_dir 看 private dispatch args；test_cli_formats_subprocess_errors 是直接 monkeypatch benchmark_cli.main 丟 Python TimeoutExpired。Rust binary 沒有對應 injection seam；實際 pipeline/summarize/front-door/OS-error 行為仍有 executable owners。

另外已修 live accounting 自己的一個重要 bug：frozen 156 是 function occurrences，不是 156 unique bare names；例如 test_rejects_bad_inputs 在 Sources/Datasets 各一條。Manifest 現在做 multiset audit 並釘住這個 duplicate sentinel，避免跨 class 同名被錯吞。下一批進 contract-sync / harness-integrity。

[t41372]

Benchmark-tooling checkpoint：live occurrence audit 已到 126 executable + 23 narrowly closed = 149/156；master 仍未 attach，仍是 83/84 / 2,862/3,018。

這一輪有一個重要 test-oracle 修正：我重新讀 frozen main@206f9ef 後發現前一個 checkpoint 抄下來的 workload SHA 有舊/錯值。已在 b0d7637c 以 frozen source 字面值校正 12 個 normal SHA + shell/js/ts broken SHA；不是為了配 Rust 輸出。Broken-workload owner 也補回 frozen 的「前 N-1 行與 valid twin 完全相同、只壞最後一行」約束。

新增 executable evidence：env/reuse/search 8；source integrity 6（精確 bytes + parser/analyzer）；repo contract-sync 5（budgets canonical、analyzer filename shared registry、3 個 benchmark workflows 統一走 Hyperfine action、legacy compare 的 pyperf pin、BENCH_CI_RUNNER == runs-on）。

新增 closures 只限已消失/被型別消除的 Python seams：pyperf worker inheritance、duplicated Hyperfine/BROKEN_LINES constants、Python console-script census、argparse private parser hash、Python subprocess.run AST timeout keyword（Rust ProcessSpec.timeout: Duration 是 mandatory field）、Python benchmark import/dev-dep AST surface。Public workflow/artifact behavior仍有 executable owners。

現在只剩 7 個 exact frozen occurrences，不再有其他暗漏：

• test_the_library_footprint_metrics_divide_into_each_other
• test_footprint_closure_bounds_and_isolates_retries
• test_rss_keeps_samples_and_full_statistics
• test_tui_keeps_import_and_rss_samples
• test_tui_records_the_selection_span_when_the_probe_measured_one
• test_cold_parse_keeps_raw_samples
• test_runover_refuses_silent_store_undercount

前 6 個我正用 public suites::run + real temp dataset/fake child endpoints 做 suite-output owners；最後一個仍是 current generate_runover 沒有 post-generate count validation 的真 implementation gap，不會 closure。

[t41372]

接手 checkpoint（固定 head 9109214acf970c25d0820c89f65caebcd021c5ec，不追移動 ref）：

• PR 目前已把 test_benchmarks_tooling.py 的 frozen 156 function occurrences 分成 133 executable + 23 narrowly architecture-closed = 156/156；最新 commit 只關閉 live manifest，master inventory/PR body 尚未正式 attach/更新。
• 我會先做最後 7 條 owner 的強度與 provenance 審查，尤其檢查 suite-output fake endpoints 是否真的走 public suites::run、retry/timeout/isolation 是否非 vacuous，以及 generate_runover 靜默少計數是否被當作 deliberate-red 而非 closure。
• 只會改 tests/test-support/master test gate；production src/、Cargo、docs、workflow 不動。測試行為紅燈保留，只有 test compile/fixture/accounting bug 會修。

完成審查後才 attach test_benchmarks_tooling.py 到 master，並貼出 exact scope/validation 結果。

[t41372]

Final-7 strength audit found test-side defects that must be fixed before master attach (these are not acceptable deliberate-red implementation findings):

1. port_test_benchmarks_tooling_suite_outputs.rs uses invented/obsolete flat keys for Footprint, RSS, TUI, and cold-analyzer raw data. Current Rust already emits the frozen Python schema (footprint.library_total_bytes.n3, raw["rss.version"]["samples_kib"], raw["n0"][...], raw["analyze_cold"]["python"]["samples_ms"]).
2. Its Footprint fixture sets RunContext.uv = None, so the public suite returns skip_all before measuring the library.
3. port_test_benchmarks_tooling_footprint_retry.rs parses fake-uv argv incorrectly (venv resolves to /bin/sh, pip --python resolves from $3), checks the nonexistent footprint.install_closure.bytes, and expects an impossible closure-call count.
4. port_test_benchmarks_tooling_runover_gap.rs searches for create_from_path, but generate_runover mutates through add_entry/commit_copy_edit; the test currently dies before reaching its intended missing-validation oracle.

I am correcting these fixtures/keys and strengthening the two silent-undercount owners. I will also replace the existing architecture closure for ordinary generate undercount with an executable post-write validation owner; the concrete store is not a reason to forfeit all evidence when the defense is present in source. Expected benchmark partition after this correction: 134 executable + 22 narrow closures = 156/156. Behavior mismatches remain red. Current head has no Actions run; only CodeRabbit reports success.

[t41372]

本輪 final-7 強度修復已完成並推送：005bc9b7365fca1cfa7173acb61a2e8629f03bc9（test(benchmarks): repair final frozen owners）。PR 描述也已更新為正式完成狀態。

Scope

• 單一提交、5 個 changed files。
• 全部是 crates/*/tests/* 或 test-only master inventory gate。
• 沒有修改 production src/、Cargo manifests/dependencies、docs 或 workflows。

最終 accounting

• tests/test_benchmarks_tooling.py: 134 executable + 22 narrowly architecture-closed = 156/156。
• 全體 frozen behavior inventory: 84/84 modules、3,018/3,018 function occurrences。
• master gate 已正式 attach 到 benchmark-tooling live manifest；closures 固定為 22，不能靜默擴張。

本輪修正的 test-side 問題

• suite-output owners 不再查 Rust 不會產生的扁平 key；改走 public suites::run，鎖住 Footprint/RSS/TUI/cold-analyzer 的真實 nested raw schema 與完整 median/p95/sample-stddev。
• Footprint fixture 不再因 uv=None 提前 skip_all。
• retry fixture 修正 fake-uv argv、真實 metric names、venv/install call count，並檢查兩秒 retry、bounded spawn、isolated cwd、完整 constructed env。
• ordinary generate 少計數從 architecture closure 提升為 executable post-write store-count evidence。
• runover owner 不再在錯誤的 create_from_path 搜尋處提前死掉。

預期紅燈

test_runover_refuses_silent_store_undercount 會刻意保持紅燈：目前 production generate_runover 在最後一次 commit 後沒有重掃真實 store，也沒有 frozen runover library has {found} entries, expected {expected} 拒絕訊息。這是 implementation parity gap，不是 test bug，也沒有被 architecture-close。

Validation

• 靜態 provenance/API/scope/strength 審查與 exact occurrence accounting 已完成。
• fake TUI/benchmark/fake-uv endpoint 已用 /bin/sh smoke-check。
• parent→head compare 確認只有上述 5 個測試／測試 gate 檔。
• 當前環境沒有可用 Rust toolchain；GitHub Actions 對 current head 仍無 run，因此不宣稱 compile/pass。CodeRabbit 為 success，且目前沒有 unresolved inline review thread。

後續 Rust 環境若揭露 test compilation/fixture 錯誤，只修測試；若揭露 behavior mismatch，保留紅燈交由 implementation agent 修 production。

[t41372]

Implementation-agent handoff note — the PR description now has a dedicated Implementation-agent handoff section so the next local Rust implementation pass does not need to reconstruct intent from the full comment history.

Key instructions for the implementation branch:

• Consume current PR head 005bc9b7365fca1cfa7173acb61a2e8629f03bc9 as a whole, preserving ancestry. If an older PR test(port): continue Python parity at stateful boundaries #44 snapshot is already integrated, merge this as the next increment rather than cherry-picking only green-looking tests.
• Treat this branch as the behavioral oracle bundle. 84/84 modules and 3,018/3,018 frozen Python test-function occurrences are accounted. Do not delete completeness/master gates when integrating.
• First distinguish test-infrastructure defects from implementation parity failures. A bad fixture/API call/compile error/test that dies before its intended oracle is test-side work. A test that reaches the Python-derived oracle and disagrees with Rust is production work; fix Rust rather than weakening the assertion.
• Do not use #[ignore], #[should_panic], dry-run substitutions, looser substring assertions, alternate accepted wording/results, or new architecture closures to manufacture green.
• Architecture closures are fixed Python-only/private/representation seams, not a place to hide missing Rust behavior. If Rust gains a real equivalent seam later, closure→executable is welcome; executable→closure because production is red is not.
• High-value deliberate-red/likely-red areas to triage first are listed in the description: benchmark generate_runover silent-undercount defense; Flows exact diagnostics/preflight/drift recovery; JS-deps ordering/argv/freshness/staging/cleanup/refusal/error contracts; Prompt/TUI Settings and Library-edit host-boundary behavior; Prompt CLI/Kind snapshot/locking/CAS/limit/error contracts.
• In particular, test_runover_refuses_silent_store_undercount is intentionally red until generate_runover verifies the real post-commit store count and preserves runover library has {found} entries, expected {expected}. Do not change that test to match the current omission.
• Suggested first local validation: cargo fmt --all --check; cargo test --locked --workspace --all-targets --all-features --no-run; exact manifest/master-accounting tests; targeted parity failures; then the broader workspace suite. This PR head has no compile-green claim because the test-port environment had no usable Rust toolchain/current-head Actions run.
• When production fixes land, keep the failure evidence traceable: small behavior-focused commits and note which frozen parity tests each fix turns green.

Authoritative disputed-behavior source remains main@206f9ef946fc45835cb2479593794431f2620c32. If current Rust is more convenient but disagrees with that frozen oracle, assume the oracle is intentional until the test itself is demonstrated defective.

Final fixed-head diff audit against 38260ff881420fbd06f95b5b9243e0caa610e370..005bc9b7365fca1cfa7173acb61a2e8629f03bc9 is complete. I reviewed the diff, not the 500+ commit history.

This increment cannot be merged or cherry-picked as one batch:

• It adds 198 split test/support paths and 1,110 unique test_* names. The current implementation branch already owns 969 of those names; 471 overlap ignored/ledger owners. Six names are duplicated inside the increment itself.
• The fixed tree fails cargo fmt --all --check on many new files.
• Workspace --no-run fails before tests execute. Independent blockers observed in an isolated scratch worktree included:
  • port_test_prompt_cli_snapshot_races.rs:159: TryLockError::kind() does not exist.
  • port_test_tui_edit.rs:84: the raw string closes at b"#... and does not parse.
  • port_test_prompt_cli_flood_plain.rs:37 and related PTY files: CommandBuilder setters return (), so the method chains do not compile.
  • port_test_launcher_target_health.rs:10: unresolved ratatui_core test dependency.
• The new support modules emit many dead-code and unreachable-public warnings, so workspace Clippy with -D warnings is also red.
• Several manifests collect names into sets before checking multiplicity, scan only hand-picked new files, and do not reject ignored/cfg-disabled owners or prove that the guard tests pass. The 3,018 frozen denominator is correct, but the master guard does not prove executable coverage.

Duplicate-name adjudication is body-based. Every candidate is compared against both the current Rust owner and the frozen Python body. One concrete rejected rewrite is test_assemble_does_not_retypecheck_plain_values: Python calls public flows.assemble, while the PR calls lower-level Rust delivery::assemble with a hand-built PreparedValue, bypassing the retyping gate under test.

Three corrected, uniquely-owned folds have landed on PR #45:

• ef5c5a2: four real-PTY runner confirmation/CAS owners. This exposed a real runner-only decline/EOF exit mismatch. The PR fixture also needed correction because set_runner seeded eight defaults instead of the oracle's single victim row.
• a219125: two JavaScript removal-lock owners moved to the real store boundary, with persistent-inode and byte-exact no-write assertions.
• f5423d4: three inject-field projection owners moved to RunFormView::from_declarations, preserving typed default/control, secret/env, binding, and delivery behavior.

The combined implementation checkpoint is green at 3,207 passed, 0 failed, and 929 ignored, with fmt, workspace Clippy -D warnings, and Rustdoc -D warnings passing.

Further useful bodies remain, but they must be folded into existing owners in small batches. Raw split files, module manifests, and the master inventory should not be imported.

Second selective fold checkpoint on PR #45: c080846.

Three more corrected batches landed after the final-head audit:

• 0e9f082: two filesystem-glob owners moved to the real FileGlobExpander. The unique owners retain main's stronger cwd/relative/hidden/sorted/multi-result checks and add the frozen literal fallback plus recursive **/x.txt behavior.
• 24e9510: five prompt-editor owners. Three-way review found that the PR's untouched test only exercised an empty file, so it could pass without proving the frozen localized starter. The corrected production/test fold now asks and validates the name before any draft/editor work, shares one EN/zh-CN/zh-TW starter helper with the TUI authoring lane, treats empty or byte-exact starter as untouched, refuses collisions before editor launch, and proves draft cleanup.
• f8091da: one existing runner-picker owner strengthened with real mouse movement/release/down events and typed submit, plus pinned/unpinned rerun owners moved to the live TUI host. The rerun tests use real child marker files and prove last-value replay (Do 1), pin-over-last-runner precedence, form fallback, and final Library routing. Controlled mouse/pin mutations made all three tests fail before restoration.

The selected-runner preflight failure contract was not imported: current production sets a status but does not route back to Library, and the PR's loose ANSI-output check cannot prove final screen state. It remains a production TDD blocker.

Current combined workspace: 3,214 passed, 0 failed, 922 ignored. Fmt, workspace Clippy with warnings denied, and Rustdoc with warnings denied pass. Exact owner count is one for every folded name.

Third selective fold checkpoint on PR #45: 8b38b3e.

Four more production-backed batches landed after three-way PR/main/Python review:

• 0f76635: the selected prompt runner's ProgramNotFound now returns the live TUI from Run form to Library with the exact localized error, no fallback child, and no form-state write. The route is scoped to prompt + resolved runner + ProgramNotFound; process failures, RunnerNotFound, non-prompt forms, and unrelated host errors retain their existing owners. The default/untouched runner path is covered, not only runner_was_picked=true.
• c9d78af: noninteractive prompt edits now report body-order unmanaged placeholders after Saved, using the already read and UTF-8-validated snapshot. The preview uses the shared 20-item limit and exact EN/zh-CN/zh-TW singular/plural tails; it does not reread or mutate body/meta/state.
• 949a51a: prompts with zero configured runners now open the shared runner editor instead of a dead Run form. Required Cancel returns to Library with the oracle message and no writes; Save reuses the existing host/store path, inserts and selects the new runner in the same form, and then runs the raw rendered prompt. Duplicate-save failure preserves modal input and config bytes. Normal Ctrl+N Cancel remains on its owner form.
• ccec2c6: malformed --prompt values with missing = or an empty name now emit the exact localized warning and continue without payload/meta/state writes. Valid prompt tweaks and other malformed axes remain unchanged and fatal where the oracle requires it.

The combined workspace is green at 3,229 passed, 0 failed, and 913 ignored. Explicit FAILING CONTRACT markers dropped from 84 to 80. Fmt, workspace Clippy with warnings denied, and Rustdoc with warnings denied pass.

The next reviewed candidate is not a raw PR file import: remaining general CLI/add/params contracts continue to require body-by-body adjudication against the frozen oracle.

Final-head selective-fold update at Rust checkpoint e2805c9:

• Accepted the stronger interaction half of test_add_review_boots_on_name_and_arrows_move into the existing canonical owner. The final test uses real Up/Down, Tab/Shift+Tab, rendered typed footer hits, Left Down, and Moved/Up refusal. Production was TDD-red before the scoped Review fix; Kind and open Select still own their arrows.
• Accepted the stronger interaction half of test_prefs_boots_on_language_and_arrows_move into the existing canonical owner. The final test keeps the current true-Tab setup, then covers shared commands through the real TUI fallback/reducer while Input, Radio, and open Select keep their keys.
• Did not activate test_add_source_arrows_walk_path_template_name: the current focus ring deliberately places BrowseSource between path and template, and that visible browse control has no other keyboard path. Skipping it would violate keyboard/mouse parity; weakening the frozen owner would be dishonest.
• Deferred the Settings arrow owner: the frozen navigation body conflicts with the current multiline boundary owner, so it needs an explicit semantic resolution before implementation.

Both accepted owners were unique, ran genuine TestBackend/key/mouse paths, produced pre-fix REDs, passed controlled reversals, and passed workspace/fmt/Clippy/Rustdoc. No PR split file, support target, manifest, or inventory guard was imported.

Selective-fold update at Rust checkpoint 1e6f9b9:

Accepted only after PR/current/frozen body comparison and independent RED→GREEN evidence:

• Prompt/editor pre-authoring: three owners now use true PTYs; non-TTY refusal and missing/blank name prompts run before editor/draft/store work. Legacy active editor tests were converted to PTY without dropping their final assertions.
• Reset live defaults: the exact owner moved from an in-memory Settings surrogate to the live CLI/TUI host; source defaults affect display clones only and open/cancel is byte-no-write.
• Current-directory and Add Source navigation: canonical bodies now include true root actions, keyboard and mouse paths, responsive geometry, exact locale labels, and input/control ownership reverses.
• Malformed runner containers and declared/store roundtrips: stronger no-write/disk/registry assertions were folded into the existing canonical owners.
• PowerShell reader+rider: the exact owner moved to the actual form seam; Python declared-first behavior remains a separate active opposite contract.
• Help taxonomy: the PR real-binary idea was retained, expanded to zh-CN and an exact 3-locale command-tree matrix.

Rejected or reclassified instead of imported:

• flows.assemble rehome to delivery::assemble bypasses the fused validation stage and is now an explicit stage-fusion closure.
• Prompt unset-runner null is the public Rust machine contract, but the frozen test reads a private Python empty-string field; it remains an unmapped private-representation row.
• Raw parameter-row preservation was mapped incorrectly through the typed writer in both current and PR bodies; raw projection and typed persistence are now separate executable owners under a split-seam closure.
• PR helper/reducer bodies are not accepted as public CLI/TUI owners when they bypass PTY, host, store, preparation, or dispatch boundaries.

No split target, manifest, or inventory guard from PR #44 was imported. Every landed fold passed workspace/fmt/Clippy/Rustdoc on its corrected owner.
