Closes five code-review backlog tasks left open by earlier waves. Each is a
follow-up the wave that found it deliberately deferred as out of its file scope.

  • TASK-2065 (PATTERN-1)resolved_workspace_members emitted literal
    [workspace].members entries verbatim, so ./crates/foo and crates/foo
    survived sort + dedup as two members and double-counted the crate in
    module_count and the ProjectUnit list. Literals are now canonicalised
    before the set operations, and the exclude-glob prefixes — which match by raw
    string prefix — are canonicalised to meet them. Unsupported glob shapes still
    pass through verbatim, because the point of emitting them is to show the
    operator the text their manifest holds.

  • TASK-2066 (DEAD-1)sql::checksum_file lost its last production caller
    when TASK-2054 moved both checksum sites onto the anchored
    IngestDir::checksum. A public by-path helper is a standing invitation to
    re-introduce the resolution the anchor exists to remove, so it is gone; the
    streaming core stays, reachable only through the anchor.

  • TASK-2067 (SEC-25) — the read_json_auto('<path>') read is the one staged
    access the anchor cannot cover, because DuckDB takes a path string and has no
    descriptor-passing API. IngestDir::verify_entry_identity now compares the
    entry's (dev, ino) through the anchor against what the path resolves to, and
    load_with_sidecar calls it inside the connection lock with nothing but the
    CREATE between check and use. This shrinks the window rather than closing
    it; the reasoning is recorded next to create_table_from_json_sql.

  • TASK-2068 (CONC-9)CARGO_LLVM_COV_TIMEOUT was a fixed 15 minutes, held
    below the dispatch budget by prose alone. TASK-2056 made that budget
    operator-configurable, so a .ops.toml could break the ordering silently: a
    60s budget still got a full fifteen-minute block in cargo llvm-cov and only
    then a report that it was over budget. The wait is now sized as
    min(ceiling, remaining on Context::deadline), so the two agree by
    construction and DEFAULT_PROVIDER_BUDGET's hand-maintained invariant retires.

  • TASK-2069 (DUP-3) — six more hand-rolled tracing-capture scaffolds, each
    with its own MakeWriter shim, its own subscriber configuration, and no
    pinned global dispatcher — the silent-flake class the shared harness exists to
    close. All six now capture through ops_core::test_utils. parallel.rs needed
    a detached subscriber because its work runs on a spawned tokio task, so
    capture_dispatch joins the harness: same configuration, same sink, and it
    pins the dispatcher.

Also fixes a pre-existing failure that blocked the ops qa gate: the ignore doctest on `Context::check_deadline` does not compile, and the `test-ignored` leg compiles ignored doctests. It is illustrative pseudo-code with an undefined `walker`, so it is marked text.

ops verify and ops qa (2995 nextest tests, doctests, --ignored, Trivy) pass
clean, as does a CodeRabbit review of the branch.

Summary by CodeRabbit

  • New Features

    • Added deadline-aware subprocess execution for coverage collection, preventing operations from exceeding their available time.
    • Added shared tracing capture utilities for reliable log collection, including events from spawned tasks.
  • Bug Fixes

    • Improved workspace path normalization and duplicate handling across platforms.

Walkthrough

Changes

Deadline-aware coverage subprocesses

Layer / File(s) Summary
Bounded subprocess API
crates/core/src/subprocess/mod.rs, extensions-rust/test-coverage/src/subprocess.rs
Adds run_cargo_bounded and computes coverage subprocess timeouts from configured limits and remaining provider deadlines.
Deadline propagation and validation
extensions-rust/test-coverage/src/{ingestor.rs,parse.rs,provider.rs}, extensions-rust/test-coverage/src/tests/*, crates/extension/src/data.rs
Passes request deadlines through coverage collection and tests unbounded, capped, shortened, expired, and configured budgets.

Shared tracing capture utilities

Layer / File(s) Summary
Detached tracing capture helper
crates/core/src/test_utils.rs
Adds and re-exports capture_dispatch, and uses it to implement capture_tracing.
Test capture migration
crates/extension/*, crates/runner/*, extensions/*, extensions/run-before-commit/*, extensions/duckdb/*
Replaces local tracing subscribers with shared capture utilities and enables the ops-core test-support feature.

Workspace member path normalization

Layer / File(s) Summary
Canonical member and exclusion paths
extensions-rust/about/src/members.rs
Normalizes member paths and exclusion prefixes before deduplication and matching. Tests cover separators, dot segments, globs, and empty paths.

Anchored DuckDB ingest verification

Layer / File(s) Summary
Staged entry identity verification
extensions/duckdb/src/ingestor.rs, extensions/duckdb/src/sql/ingest/{dir.rs,sql.rs}, extensions-rust/test-coverage/src/tests/wiring.rs
Verifies staged inode identity before DuckDB performs the path-based JSON read.
Anchored checksum API and exports
extensions/duckdb/src/sql/{mod.rs,ingest/mod.rs}, extensions/duckdb/src/sql/ingest/dir.rs
Removes the path-based checksum helper and updates checksum tests to use anchored staging.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to be3ab

The PR changes workspace exclusion matching and subprocess timeout behavior, but the current implementation can cause .* exclusions to hide all single-segment members rather than only hidden ones. It also has bounded configuration-compatibility and test-environment issues, so the PR should not merge until these are addressed or explicitly accepted.

Use the required CARGO_OPS_* environment-variable namespace.

cached_subprocess_timeout reads TIMEOUT_ENV, defined as OPS_SUBPROCESS_TIMEOUT_SECS. Rename it to CARGO_OPS_SUBPROCESS_TIMEOUT_SECS and update the documentation. Keep the old name only as an explicit compatibility alias.

Preserve a dot partial-segment prefix.

Line 230 removes the . from the supported partial prefix in exclude = [".*"]. The stored prefix then becomes empty. ExcludeSet::excludes treats that as a wildcard for every one-segment member.

Keep a final partial . segment when it directly precedes *. Add coverage for ExcludeSet::from_entries(&[".*".to_string()]) to verify that it excludes .hidden but not crates.

Use the resolved timeout in these assertions.

llvm_cov_timeout uses default_timeout(CARGO_LLVM_COV_TIMEOUT). OPS_SUBPROCESS_TIMEOUT_SECS can change that value. These tests fail in an environment with that setting, even when the implementation is correct. Derive both the expected value and the far deadline from default_timeout.

 fn llvm_cov_timeout_without_a_deadline_is_the_operation_ceiling() {
