recursively before writing the packages.dirty marker, so the marker write
succeeds if the directory was removed while the lock was held.

used by withPackagesLock: catch errors from the ownership check and rmSync, and
report them through bufferLog so cleanup failures do not escape and replace the

exit code before accepting a passing summary or `noTests`. Preserve success for
completed runs with benign stderr warnings.

…re-read the manifest `altimate-dbt` ran `dbt deps` on every start, and concurrent invocations corrupted `dbt_packages`. Packages are now installed only when missing, out of date or half-written, under a cross-process lock with a heartbeat and stale-lock handling. `deps` and `add-packages` take the same lock. With the install no longer staggering start-up, concurrent processes could read `target/manifest.json` while dbt rewrote it, so reading the manifest now retries with jittered backoff. `schema-verify` now fails only on what dbt treats as an error (an enforced contract the built relation does not match, a declared column with a test that the model does not produce) and never tells the agent to remove columns. Adds `yaml` as a direct dependency of `dbt-tools` (already in the lockfile through other workspaces) for reading `packages.yml` and `dbt_project.yml`. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…tests-pass` - `dbt-schema-verify` no longer instructs the agent to remove or add columns so a model matches its YAML; it reports only real dbt errors, names the file that declares the column, and suggests no destructive change. - `dbt-tests-pass` treats dbt's "Nothing to do" (a model with no tests) as "nothing to check" rather than "could not be tested". Failing tests and real run errors still fail. - An `altimate-dbt` check that errors is retried once on its own, because the validators run several processes against one single-writer DuckDB file. - Rewrites the `dbt-schema-verify` and `dbt-develop` skills that taught the old rule, and updates the validator and dbt-tools docs. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…bt's own deps error Findings from the independent review: - Hub packages do not keep `version:` in their `dbt_project.yml` in step with the release (a package locked at 1.3.0 reports 0.1.0), so comparing it with the lock reinstalled on every start. Installed packages are now checked by name and completeness; a stamp from our own install still detects changed declarations. - A failed explicit `altimate-dbt deps` on an empty directory returns dbt's error result instead of a generic "incomplete" exception. - Plain files and dangling links in the install path are not counted as incomplete packages. - The "after waiting for the lock" reason was inverted. - The dbt-tools `test` script now also runs `schema-verify.test.ts` and `build.test.ts`. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
…ator retries - Install packages from `create()` so every caller of the dbt adapter (including the in-process SQL path) gets the install check; a lock wait timeout is now fatal rather than continuing against packages being rewritten. - Treat a truncated `dbt_project.yml` as an incomplete package, fall back to `packages.yml` when `package-lock.yml` is empty, recreate the state directory before writing the dirty marker, and make lock release best-effort. - Find the tested model through `depends_on` for manifests without `attached_node`. - `dbt-tests-pass`: a passing summary next to dbt abort text is an error, a zero-test summary is not counted as passed, and a retry that cannot start keeps the first error. - Sanitize schema-verify evidence and error text before they reach the prompt. - Correct the skill and validator docs, and tighten test assertions.

…and adapter - Include the resolved `packages-install-path` in the install stamp, so changing it no longer leaves a stamp that vouches for another directory. - Dispose the initialised adapter when the manifest read in `create()` throws. - Scan the project's tests for tested columns only when a declared column is missing and no contract is enforced. - Allow 1200 characters of schema-verify evidence so a model with many missing tested columns keeps all of them in the message. - Make the dbt-tools no-destructive-guidance assertion case-insensitive.

Issue for this PR
Closes #1419
Type of change
What does this PR do?
Why. A live ADE-Bench run showed the finish-time dbt validators and the altimate-dbt helper sending agents into repair loops over problems that did not exist (#1419).
Root cause and fix, per defect
Dependency change. packages/dbt-tools/package.json adds yaml 2.8.3 as a direct dependency (used to read package declarations and dbt_project.yml), and the lockfile gains the one matching workspace line. The test script also runs the new test files.
Before and after (live, ADE-Bench, 75 tasks per arm, one trial each, origin/main against the fixed tree)
No pass-rate improvement is claimed. Passes were 55 of 75 against 59 of 75; paired difference +0.053, 95% interval -0.040 to +0.147, which includes zero. Four tasks passed only without the fixes (f1006.base, f1010.medium, f1011.base, intercom002.base); with one trial per task I have not established the cause of each.
Caveat. The live numbers were measured before the manifest retry (defect 5) was added; that change is verified by stress test only.
Deployment readiness. Self-contained; no migration, configuration or operator action.
Tenant and user impact. Two changes a user could notice. (a) Edits made inside the packages directory now persist until altimate-dbt deps is run; previously every call reinstalled pristine packages. (b) Validators stay silent where they used to speak: no "could not be tested" for untested models, and no column advice for undocumented columns.
Known limits, documented and not fixed. A paused lock owner resuming beside its replacement, or a killed owner leaving its dbt deps child; readers racing a user's explicit dbt deps; a raw dbt deps bypassing the lock. Windows and dbt Fusion untested. Installed package versions are not compared, because hub packages report stale versions in their own project file. When no manifest exists at all, each read now costs about 2 to 3 s of retries.
Pre-existing: the typecheck error in trace-context-loop.test.ts is not reported on this branch, rebased on the latest main.
