Group the 27 Triage findings from the 2026-08-28 review pass into ten code-review-plan-wave parent tasks, each carrying its file scope and overlap notes, and flip every grouped member to To Do under its wave.

SEC-38 / TASK-2018: `DuckDbHandle` has a blanket impl over every 'static + Send + Sync type, and `Arc<dyn DuckDbHandle>` is one of them, so wherever the trait is in scope method resolution on an Arc receiver matches the blanket impl for the smart pointer and `as_any()` erases the Arc. Every downcast to `DuckDb` then returns None, silently. `downcast_duckdb` only resolved correctly because this module happens not to import `DuckDbHandle` by name — one `use` away from turning `get_db` and `try_provide_from_db` into unconditional cache misses with no error anywhere. Reborrow to `&dyn DuckDbHandle` explicitly so resolution no longer depends on the import list, and pin both halves with tests that call the accessors from a module where the trait is deliberately in scope.

SEC-38 / TASK-2018: correct the downcast contract — whether an Arc receiver misresolves depends on whether the importing module names the trait, which is what makes the hazard invisible — and record the decision not to narrow the blanket impl, with the three rejected alternatives and why the containment lives in `ops_duckdb::get_db` / `try_provide_from_db` instead.

SEC-32 / TASK-2033: `cleanup_staged_file` sat immediately before `Ok(...)`, so `init_schema`, `build_views`, the record count, the ERR-1 / TASK-1891 non-singleton rejection, the workspace-root extract and the checksum/upsert all returned via `?` and left a full `cargo metadata` dump — every workspace member, every dependency and absolute local paths — on disk indefinitely. Replace the single call site with a `StagedFile` guard armed before the first fallible step, mirroring the terraform pipeline's SEC-32 / TASK-1927 cleanup, and stop warning on `NotFound` now that cleanup also runs when nothing was staged.

…being in scope SEC-38 / TASK-2018: the TEST-5 / TASK-1877 comment stated the misresolution unconditionally, which the corrected `DuckDbHandle` contract now qualifies. The blanket impl is only a method-resolution candidate where the trait is in scope, which is why `ops_duckdb::downcast_duckdb` — in a module that never imported it — downcast correctly while this test asserted the opposite.

… in logs
Command ids and aliases come from .ops.toml table keys and `aliases` arrays,
which have no character restrictions. Under the Display (`%`) formatter an
embedded newline could forge what reads as an extra log record and an ANSI
escape could repaint the operator's terminal. Render them with `?` instead,
applied to `as_str()` on CommandId so the field stays a bare quoted id rather
than `CommandId("x")`.
Completes the SEC-21 policy already applied to `program` (TASK-1127), tap
paths (TASK-0940) and env keys (TASK-1937).

The post-exit drain grace was a compile-time 5s constant, unlike every other resource knob in the crate, even though reaching it now SIGKILLs a descendant process. Expose it as OPS_OUTPUT_DRAIN_GRACE_SECS through parallel.rs's existing resolve_env_usize, so it answers to the same parse / clamp / warn-on-fallback contract as OPS_MAX_PARALLEL and OPS_OUTPUT_BYTE_CAP rather than a second copy of it. Default stays 5s; the 3600s ceiling stops an operator restoring the unbounded pre-TASK-1919 hang. Also renders the remaining config-derived ids in these two files with the Debug formatter, per the SEC-21 sweep in the previous commit.

Installing a tokio signal handler replaces the default disposition for the rest of the process's life, so once run_until_signal had taken its shutdown arm every further SIGINT/SIGTERM was swallowed by a stream nobody reads. A slow or wedged teardown was therefore inescapable, removing the escape hatch users had before the graceful path existed. Restore SIG_DFL for both signals inside the signal arms -- before the losing plan future is dropped, so the teardown itself stays escapable. The second signal then kills the process as it would have before, which shells report as 128+signo. That path bypasses unwinding, so EchoGuard's Drop does not run; the trade-off is documented on the reset and in EchoGuard's Drop-paths table.

- Around line 1197-1201: The SIGINT/SIGTERM reset test must not share a process
with sigterm_interrupts_the_plan_and_reports_sigterm. Update the test harness
around the affected signal test to execute it in a child process or otherwise
provide process isolation, preserving the existing signal assertions and
avoiding reliance on serial_test ordering.
In `@crates/extension/src/data.rs`:
- Line 632: Update the context configuration containing provider_budget and
DEFAULT_PROVIDER_BUDGET so its budget is at least 15 minutes, matching the
CoverageProvider cargo llvm-cov timeout; preserve the existing
DataRegistry::provide timeout handling and avoid changing unrelated subprocess
behavior.
In `@extensions-rust/about/src/manifest.rs`:
- Around line 516-518: Use a single serial_test group containing both
typed_manifest_cache and workspace_root_cache for
workspace_root_resolution_is_memoized_per_cwd and every other manifest test that
calls workspace_root_cache::evict; replace any stacked or workspace-root-only
serial attributes while preserving the tests’ existing behavior.
In `@extensions-terraform/about/src/lib.rs`:
- Around line 367-373: Update is_heredoc_ident_start and is_heredoc_ident_char
to recognize HCL-compatible Unicode UAX `#31` identifier characters, while
preserving the existing underscore and hyphen rules where applicable. Ensure
heredoc_terminator accepts Unicode identifiers such as 終端, and add a regression
test covering a Unicode heredoc terminator with body syntax characters and
subsequent required_version parsing.
- Line 307: Preserve heredoc indentation mode in scan_line and strip_comments:
record whether each opener uses <<-, then require exact terminator matching for
ordinary heredocs and trimmed matching only for indented heredocs. Apply this
matching logic at both extensions-terraform/about/src/lib.rs lines 307-307 and
561-561.
In `@extensions/duckdb/src/sql/ingest/dir.rs`:
- Line 205: Keep the staging parent pinned for the entire lifecycle: update
harden_ingest_parent, create_ingest_dir, and provide_via_ingestor to use
descriptor-relative operations rather than reopening or passing the plain parent
path to collect, load, and sidecar actions. If descriptor-relative handling
cannot cover a path, reject untrusted symbolic parent components, and add a Unix
regression test covering ancestor replacement.
- Around line 222-228: Update harden_ingest_parent’s sticky shared-writable
handling to validate the directory owner against the trusted-owner policy before
returning success; reject the parent when ownership is untrusted, while
preserving acceptance only for trusted owners.

The HCL scanner matched a heredoc terminator on the trimmed line for both spellings, so an indented look-alike ended an ordinary `<<EOT` body early and the rest of it was read as structure. Track whether the opener was `<<-` and apply HCL's rule: leading whitespace is tolerated only for the indented form. Terminator identifiers were also ASCII-only, so `<<終端` never opened a heredoc at all — the same failure TASK-2031 fixed, reached through a Unicode name.

DEFAULT_PROVIDER_BUDGET was 600s while ops-test-coverage waits up to 15 minutes on `cargo llvm-cov`, so a coverage run between those two bounds was reported as TimedOut despite being within its own limit. Raise it to 20 minutes and document the ordering the two constants have to keep. An overrun also converted *any* result to TimedOut, replacing a provider's own failure with the news that it was slow; only a successful result converts now. Also make nested_dispatch_inherits_the_outermost_deadline actually nest: it checked one provider's deadline twice rather than dispatching through the registry, so it never exercised begin_deadline / clear_deadline_if_owned on an inner call.

… tests These tests clear the process-global cache and assert exact entry counts, but held only the `workspace_root_cache` key while load_workspace_manifest's tests populate that same cache under `typed_manifest_cache`.

The sticky bit was accepted as sufficient proof that names inside the staging parent cannot be swapped, but it binds every principal except the directory's own owner, who can clear it, chmod the directory, or replace it. That trusted a co-tenant's 0o1777 directory exactly as much as /tmp. Require the owner to be root or ourselves.

`char::is_alphanumeric` was the wrong alphabet for an HCL identifier: it admits only combining marks carrying `Other_Alphabetic`, so a Devanagari vowel sign passed while `U+0301 COMBINING ACUTE ACCENT` did not. A decomposed `<<é` had its terminator truncated to `e`, the real closing line never matched, and the rest of the file was swallowed as heredoc body — the failure TASK-2031 exists to prevent, reached through a name the previous fix claimed to support. Use `unicode-ident`'s generated `XID_Start` / `XID_Continue` tables instead, and say plainly in the docs where XID differs from HCL's `ID_*`.

- Line 419: Replace the unicode_ident::is_xid_start check with HCL-compatible
ID_Start/ID_Continue handling in the identifier or heredoc opener scanner, while
preserving underscore support and allowing '-' only as specified for
continuation. Ensure U+037A is recognized as a valid starter and add a
regression test covering a heredoc opener followed by body braces and a later
required_version.

code-review run 2026-08-29 — 10 waves
Ten
code-review-plan-waveparents (waves 179–188) covering the 27 findings from the2026-08-28 review pass. Every wave ran in its own git worktree and landed on this branch
through the shared merge lock. All ten landed; none parked.
Waves
✓done ·~done with a recorded AC substitution ·✗left open (none)Merge order as executed: 180, 182, 184, 181, 187, 179, 186, 185, 188, 183.
Only wave 184 hit a fast-forward refusal — the landing branch advanced under its lock
because bookkeeping commits are made under a different lock. It re-rebased and landed.
Wave 183 was the one real rebase conflict, in
extensions-rust/deps/against wave 188'sCwdGuardremoval; both sides were preserved. The two overlaps triage predicted(
manifest.rsbetween 185/186,extensions-terraform/about/src/lib.rsbetween 183/188)did not conflict.
What changed
tracingthrough the Debug formatter across ops-runner. Every
OpsTablecell built from externaltext is control-character sanitised (the terraform-local sanitiser moved into
ops-core). The gitdir containment anchor is floored below the filesystem root; aworkspace manifest resolving outside its own directory is rejected; the duckdb ingest
staging parent is made unwritable to other principals through the open handle.
SharedError::source()now yields its inner error, andFrom<anyhow::Error>no longer boxes through anyhow's internal wrapper — both wereneeded for typed downcasts to work. The terraform HCL scanner understands heredocs
(a bare
}in a heredoc body was refusing whole files). Tab measures and paints as onecolumn.
workspace.excludeexpands globs likemembersdoes.DataProviderdispatch is bounded by a wall-clock budget with acancellation point providers can poll. The post-exit drain deadline is operator-tunable
via
OPS_OUTPUT_DRAIN_GRACE_SECS. A second Ctrl-C force-quits a wedged shutdown.The staged
metadata.jsonis removed on every error path.cache hits no longer re-canonicalize the ancestor chain.
CwdGuardcollapsed onto singleimplementations in
ops_core::test_utils(moved down the graph to avoid acore→about dependency cycle).

ops verifyon the combined result: 7/7 green.cargo nextest run --workspace --all-features: 2952 passed, 0 failed.Note for anyone reproducing locally:
ops verify's build step needsDUCKDB_LIB_DIRset(
eval "$(scripts/fetch-duckdb.sh)"), otherwise linking fails withlibrary not found: duckdb. That is an environment precondition, not a change in this PR.Follow-ups filed (Triage)
Nine tasks, all discovered by runners and filed rather than left as prose:
Context::check_deadline, sothe new dispatch bound is post-hoc only. The deferred architectural remainder of SEC-33.
ops verifylints only--all-features, so feature-off code can go redwithout failing the gate (the class of defect wave 187 fixed).
Ingestor::collect/loadandsidecar.rsstill reopen the ingest dirby path after verification.
workspace.excludedoesn't drop members nested under an excluded path.TracingBufconsumers still hand-roll the subscriber.Note on TASK-2018 (SEC-38)
The filed premise did not reproduce. The
Arc-receiver misresolution is latent, notlive: the blanket impl is only a method-resolution candidate where
DuckDbHandleis inscope, and
extensions/duckdbnever imports it. Oneuseaway from turning everyDB-backed lookup into a silent cache miss. The reborrow landed as containment and the
misleading doc comment in
crates/extension/src/tests.rswas corrected.🤖 Generated with Claude Code
