From fad0a34cfc8c5ec4ad148b4843c5f11092e057bb Mon Sep 17 00:00:00 2001 From: danielmeppiel Date: Fri, 2 Oct 2026 15:28:31 +0200 Subject: [PATCH 01/18] fix(hooks): render native Cursor hooks with import coexistence checks Repair the bounded native output and lifecycle scope for #3129. Reject unrepresentable semantics and duplicate Claude import activation before primitive writes, while retaining ownership, consent, and target restrictions.

A target legitimately being retired this run could then be misflagged as a Cursor/Claude import-coexistence conflict. Threaded retiring_targets through _integrate_merged_hooks() and integrate_hooks_for_target(); services.py now forwards it from target_selection.excluded_targets, mirroring the existing fast-path expression. - Added a mutation-provable wiring regression test (test_fallback_preflight_forwards_retiring_targets) asserting the forwarded kwarg directly; mutation-break/restore confirmed it fails without the fix. - Compacted two pre-existing HookIntegrationResult empty-result constructions to make room for the new parameter within the 2100-line file-length budget (no behavior change). - test_cursor_hook_lifecycle.py: normalized whitespace before the "Claude import" substring assertion. Root cause: the HookContractError message is printed via Rich Console().print() with no explicit width, so CI's narrower/non-TTY terminal word-wraps the diagnostic and can split "Claude import" across a line break (confirmed via a real Console(width=20) reproduction, not conjecture). - test_console_utils.py: added a narrow-width regression test (TestRichErrorNarrowWidthWrapping) using a real Rich Console to prove the wrap/normalize behavior against the exact production error text; mutation-break/restore confirmed the existing unknown-top-level-keys guard trap still fails/passes correctly.

Narrowly bound to the accepted Cursor-native(+Claude-import) capability only, not a universal target-native obligation. Includes vendor-grounded editorial note (cursor.com/docs/hooks, cursor.com/docs/reference/third-party-hooks) distinguishing APM's own conservative conversion/safety policy from vendor-documented defaults (vendor default is merge-not-reject; vendor top-level shape is not documented as closed). Updates Section 8.7 and 11.3.2 enumerations, Appendix C (2 new rows, total 127 statements / 122 MUST), the requirements manifest, the 0.1.44 (proposed) revision-history row, regenerated CONFORMANCE artifacts, and new drift-sentinel conformance tests (tests/spec_conformance/test_cursor_hook_reqs.py) citing the already-existing, already-passing behavioral integration tests. Folds 4 round-1 findings from the real apm-spec-guardian 4-persona panel (spec-swagger-editor, spec-oci-editor, spec-pkgmgr-editor, spec-tag-architect; synthesizer ship_decision=fold_and_ship, shocked_meter_avg=8.0, 0 blockers across all 4 panels): - req-tg-017: defines the "observable overlap" predicate normatively (non-empty hook-event-identifier intersection after alias normalization), closing a 4/4-panel-convergent second-implementer reproducibility gap. - req-tg-016: adds a SHOULD-level sentence requiring implementations to document/expose their accepted source-format vocabulary, so conformance claims are independently verifiable. - Editorial note: drops the stale "eight" alias count (staleness magnet in informative text). - 0.1.44 revision row: adds a one-line clarification that revision label 0.1.43 and requirement id req-tg-015 are reserved by a concurrent sibling unit (PR #3150) on its own branch, not an unintentional gap. Deferred to v0.1.1 (not folded here, too heavy for a surgical mechanical fold): a machine-readable accepted-vocabulary artifact, and a stale- partial-artifact disposition clause for req-tg-016. Rejected: the stale cursor_preflight_done cache-bypass surface (out of scope, requires a src/apm_cli/** change this unit does not authorize) and the full vocabulary-artifact proposal (superseded by the lighter SHOULD-sentence folded above). No src/apm_cli/** changes. No spec waiver. Statement count unchanged at 127 (122 MUST, 5 SHOULD) -- this fold is prose-only, no new anchors. tests/spec_conformance/ re-verified: 293 passed, 2 skipped (orphan 4-way invariant intact). Closes the Spec conformance gate gap for PR #3149 / issue #3129.

The preflight check is now unconditional on both call sites. Corrects req-tg-017's "observable overlap" definition to a kind-aware (event, handler kind, handler content) tuple comparison, grounded in vendor docs confirming Cursor supports both command and prompt hooks; clarifies that unknown-field rejection is APM's own conversion policy, not an assumed vendor schema closure. Also clarifies the "declared source package ownership" clause to reference the implementation's own internal provenance marker. Adds five mutation-proof regression tests covering the reused-plan bypass, two spec-conformance tests for req-tg-016/017, and a new req-lk-021 Cursor lockfile-reconciliation test mirroring the existing Codex coverage.

The prior _nhc_cursor_edge lexical-presence check could not catch this shape (the literal call text survives being wrapped in a conditional); proven via mutation testing before and after the fix. - test_architecture_owner_rule_mutations.py: add a standalone (non-matrix) regression test exercising the new sub-check directly through run_selected_rules, following the existing pattern for guards that need more than one proof beyond the frozen one-guard one-mutation matrix. - test_cursor_hook_reqs.py (req-tg-017): add a genuine default-predicate overlap-rejection test using the real nested Claude handler shape with the same (event, kind, content) as the source, so the requirement is proven against the unpatched predicate, not just a kind-blind mutant. - test_cursor_hook_native_contract.py: add a reused-plan regression covering preflight-in-project-A-then-switch-to-project-B BEFORE any native write occurs in A, complementing the existing write-then-switch case; both project roots are asserted unwritten and the Claude import is byte-preserved. Also fix an ASCII-only violation (a Unicode box-drawing separator) flagged during review. - CONFORMANCE.json/.md: regenerated; req-tg-017 test_count 2 -> 3, no new anchors or statement-count changes.

The prior _nhc_cursor_preflight_unconditional check only banned the literal token "cursor_preflight_done", missing both outright call removal and re-gating under any other predicate name. Add _nhc_cursor_preflight_call_site: an AST-based, call-site specific guard that locates HookIntegrator._integrate_merged_hooks, finds its direct-body If whose test unparses to the legitimate 'config.target_key in {cursor, claude}' guard, and requires one of that If's own direct body statements to be an unconditional preflight_cursor_hooks(...) call. Deleting the call, or wrapping it in any further nested conditional (any predicate name), now fails this check regardless of whether the substring survives elsewhere in the file. The existing token-ban and file-wide presence checks are preserved unchanged as independent sub-checks. Add two regression tests reproducing both exploit shapes against the real source: outright call-site removal (while the unrelated call site keeps the substring present) and a renamed cache predicate re-wrap (while the banned token stays absent). Both previously passed the guard with zero violations; both now correctly produce exactly one violation.

Fix a prior inaccurate "malformed configuration" characterization of provenance-marker loss. - hooks-and-commands.md, package-authoring.md: fix forward-referenced "owner" terminology and clarify provenance-marker substitution behavior to match the corrected spec wording. - test_cursor_hook_reqs.py: correct a spec-conformance fixture needle to match the corrected req-tg-017 wording. - test_install_cli_cursor_claude_import_recheck_e2e.py: narrow an overbroad LOAD-BEARING docstring claim to what the test actually asserts. - test_cursor_hook_native_contract.py: add a unit-level Windsurf lifecycle case alongside the existing Cursor case. - test_package_target_hook_routing_e2e.py: add an installed-CLI (packaged-binary) Cursor+Windsurf widen-then-narrow regression test covering the Cursor-only -> Cursor+Windsurf -> Cursor-only package target lifecycle. Asserts Cursor hooks are untouched throughout, the owned Windsurf hook appears on widen and is retired on narrow, and an unowned (manually authored) Windsurf hook survives both transitions. Verified via a scoped source mutation + binary rebuild cycle (disabling the Windsurf branch of the owned-hook cleanup guard in reconcile_package_target_restriction): the new test fails with the exact expected "owned windsurf entries must be retired" assertion under the mutant, and passes once reverted and rebuilt.
