+# Trusted `uv.lock` materialization: evidence and design record
+
+## Decision
+
+Central coverage automation may translate a tracked `uv.lock` from the exact
+validated pull-request base revision into a pip-compatible, hash-pinned
+requirements closure. The translation must not depend on a mutable runner tool,
+repository-head dependency metadata, or network access during export.
+
+The implementation therefore:
+
+1. reads `uv.lock` and its sibling `pyproject.toml` only through `git show` at a
+   validated 40-character commit SHA;
+2. downloads one fixed official Astral `uv` archive from a literal HTTPS URL;
+3. verifies the bounded archive with a pinned SHA-256 digest before extraction;
+4. accepts only the expected regular-file tar member within explicit size bounds;
+5. verifies the installed executable reports the exact pinned `uv` version;
+6. executes `uv export` with `--frozen`, `--offline`, `--no-emit-project`, and
+   `--no-editable` in an isolated temporary project;
+7. rejects every nonempty export unless every logical requirement carries an
+   explicit `--hash=` value; and
+8. exposes only generated requirements files and a source manifest to the later
+   networkless coverage environment.
+
+## Standards and current-tool rationale
+
+The approved SLSA specification is version 1.2. Its provenance model treats
+verifiable origin and production history as software-supply-chain evidence, and
+its source track distinguishes trusted robots whose identity and codebase cannot
+be unilaterally influenced. Binding reads to an immutable Git revision, pinning
+the exporter artifact by digest, and rejecting malformed exporter output follow
+that trust-minimization direction without claiming a SLSA conformance level.
+
+Astral documents `uv export` as the supported conversion path from `uv.lock` to a
+pip-compatible requirements format. The command is invoked with `--frozen` so it
+cannot update the lock and `--offline` so the conversion cannot access the
+network. Project and editable entries are omitted because the coverage sandbox
+loads repository source directly and needs only the third-party dependency
+closure.
+
+Generic requirements discovery continues to accept a global
+`--require-hashes` directive because pip performs a later closure preflight.
+Trusted `uv export` output uses a stricter rule: each emitted requirement must
+carry its own hash. This prevents a successful but malformed exporter result
+such as `--require-hashes` followed by an unhashed requirement from entering the
+trusted build context.
+
+## Verification contract
+
+Regression coverage must prove:
+
+- base-revision-only reads and rejection of unsafe revision/path shapes;
+- fixed-origin download, redirect rejection, bounded reads, archive digest,
+  member type, member size, executable size, and exact executable version;
+- frozen and offline exporter arguments;
+- timeout, process, parse, and exporter failures fail closed;
+- orphan locks and empty third-party closures remain nonfatal and explicit;
+- every nonempty emitted requirement includes a hash; and
+- the changed production module retains 100% statement and branch coverage and
+  100% production docstrings.

+A true uv workspace can require member `pyproject.toml` files in addition to the

+## Repository-wide branch-coverage prerequisite repair
+
+The exact pull-request merge tree exposed a broader central quality-contract
+failure after the trusted uv slice itself had reached complete statement and
+branch coverage. The complete repository suite passed all 850 tests, but the
+shared OpenCode coverage command still exited nonzero because 52 defensive
+branch arcs in unchanged central CI modules were not exercised. The measured
+production result was 100% statements and 99% branches. Treating that outcome as
+a uv exporter defect would have hidden the actual control-plane gap.
+
+The repair does not narrow the production source set, omit unchanged modules,
+lower `fail_under`, or add coverage pragmas. It adds deterministic regression
+tests for the previously unexecuted scheduler, redaction, sandbox, JavaScript
+coverage, R coverage, SBOM, approval, and evidence-contract branches. The
+dedicated quality workflow now runs both the bounded trusted-uv slice and the
+complete central test suite under branch measurement. This keeps the narrow
+feature evidence useful while also proving the organization-wide 100% contract
+that OpenCode enforces on the merge tree.
+
+The repaired merge tree produced the following deterministic evidence:
+
+- 883 tests passed;
+- 6,573 of 6,573 production statements executed;
+- 2,622 of 2,622 production branches executed;
+- no missing production lines or partial branches; and
+- every production module, class, and function in `scripts/ci` retained a
+  docstring.
+
+This prerequisite repair is intentionally test-only for production behavior. It
+changes neither the trusted uv download boundary nor the dependency closure
+accepted by the coverage sandbox.

+# Strix NVIDIA NIM model-catalog fallback: evidence and design record
+
+## Decision
+
+Strix treats an authenticated NVIDIA NIM model-catalog `404 Not Found` as
+provider availability evidence, not as a target-application vulnerability. The
+gate does not retry the same unavailable model. It proceeds to a distinct
+reviewed NVIDIA hosted model and only then to the existing GitHub Models
+candidates.
+
+Public-repository scans now default to
+`nvidia/nemotron-3-super-120b-a12b`. The first fallback is
+`nvidia/llama-3.3-nemotron-super-49b-v1.5`. Private repositories retain the
+contracted provider because NVIDIA hosted trial inputs are restricted to public
+repositories by the central workflow.
+
+## Trust boundary
+
+The NVIDIA classifier accepts only a single bounded log line that contains all
+three signals: a LiteLLM `NotFoundError`, NVIDIA NIM provider context, and
+model-catalog not-found evidence. It does not assemble provider and `404`
+signals from different lines. A bare application `404`, route miss, database
+lookup miss, provider-like source literal, or other target-controlled output is
+not enough to enter model fallback.
+
+This same-line rule matters because scanner stdout can include text derived from
+the repository under review. Requiring the trusted LiteLLM exception marker and
+all provider-availability evidence on one line prevents repository content from
+combining with an unrelated application `404` to spoof infrastructure fallback.
+Provider-side failure also remains a fail-closed incomplete scan until a distinct
+fallback produces complete evidence.
+
+The outer workflow may classify exhausted provider infrastructure as neutral only
+when the run log contains no vulnerability signal. Any reported severity or
+non-zero vulnerability count remains blocking. Scanner reports and attempt logs
+remain available as artifacts.
+
+## Verification contract
+
+Regression evidence proves that:
+
+1. the exact LiteLLM `Nvidia_nimException` 404 observed in required CI is
+   recognized;
+2. an ordinary application 404 is not recognized;
+3. provider context and 404 evidence on different lines are not recognized;
+4. a provider-like source literal on one line without LiteLLM `NotFoundError`
+   context is not recognized;
+5. model-catalog 404s enter cross-model fallback but never same-model retry;
+6. the primary and first fallback are current NVIDIA hosted models;
+7. GitHub Models remain later cross-provider fallbacks;
+8. vulnerability signals prevent neutral infrastructure classification; and
+9. the required-workflow smoke contract pins these properties.
+
+## Limitations
+
+Hosted model catalogs may change independently of this repository. A model-card
+page or supported self-hosted NIM container does not guarantee indefinite hosted
+trial availability. The ordered model plan must therefore be reviewed against
+current NVIDIA documentation whenever a provider returns a catalog 404. This
+change does not treat arbitrary provider errors as success and does not weaken
+Strix severity, changed-file attribution, or independent approval requirements.

 ## [Unreleased]
 
+### Added
+
+- Added exact-base `uv.lock` materialization that reconstructs standalone nested projects with a checksum-pinned official `uv` exporter, isolated frozen/offline execution, strict exact-pin and SHA-256 output validation, and complete Python 3.10/3.14 quality evidence.
+
 ### Fixed
 
+- Bound both trusted-uv quality jobs to `github.event.pull_request.head.sha` and added a permanent two-checkout regression contract so exact-head compatibility, coverage, docstring, and compilation claims cannot silently measure GitHub's generated pull-request merge revision.
 - Made Strix treat only a single LiteLLM provider-error line containing NVIDIA NIM context and model-catalog 404 evidence as cross-model fallback evidence, rejecting cross-line signal assembly and provider-like target source literals; moved the public default to Nemotron 3 Super 120B and added a second NVIDIA hosted candidate before GitHub Models without neutralizing reported vulnerabilities.

+## Exact-head quality evidence
+
+GitHub documents that a workflow triggered by `pull_request` normally receives
+`GITHUB_REF` as `refs/pull/<number>/merge` and `GITHUB_SHA` as the generated
+merge revision. That behavior is useful for integration testing, but it cannot
+support a claim that compatibility, coverage, docstrings, and compilation were
+measured on the contributor's immutable head.
+
+Both jobs in the dedicated trusted-uv quality workflow therefore pass
+`github.event.pull_request.head.sha` explicitly to `actions/checkout`. The
+workflow remains read-only and disables credential persistence. A permanent
+contract requires the exact-head `ref` on both checkout steps, so a future edit
+cannot silently convert exact-head evidence back into merge-preview evidence.
+On a `push` event the pull-request field is absent; the checkout action receives
+its documented empty default and continues to use the ref or SHA that triggered
+the push.

+# Trusted uv quality regression repair evidence
+
+Exact head `d3b6c79aed988120ce70c08274d76127a04a0c41` failed the Python 3.14 complete quality gate because two tests had stale environmental assumptions.
+
+The Git safety test depended on a private Git test hook producing a dubious-ownership failure. Git 2.54.0 on the hosted runner returned success. The repaired test now inspects the effective protected configuration directly and requires exactly one `safe.directory` entry equal to the validated worktree, with neither an unrelated repository nor a wildcard.
+
+The Strix fallback test still supplied a retired model identifier after the reviewed policy changed the unrequested public default. The repaired test now supplies the current default and continues to prove that an unavailable default credential selects the established fallback.
+
+One-shot workflow run `30976255239` completed successfully and removed itself. It passed both focused regressions, the complete central pytest suite under coverage, production docstring enforcement for `scripts/ci`, and Python compilation.
+
+The repair changes test evidence only. It does not weaken trusted dependency materialization, provider selection, security scans, or the exact-head merge policy.

+`safe.directory` only from protected configuration scopes. A hosted runner may
+therefore carry a system or global trust entry that makes both repositories look
+safe and turns the negative control into a false pass.
+
+The test now supplies an isolated `HOME` and `XDG_CONFIG_HOME`, disables system
+configuration with `GIT_CONFIG_NOSYSTEM`, and points global configuration at the
+null device before adding one command-scope `safe.directory` entry. The selected
+worktree must succeed, while a sibling repository must still fail with dubious
+ownership. This tests the production boundary rather than the runner image's
+ambient policy. Git 2.54.0 retains the test-only different-owner switch and
+resolves `safe.directory` through protected configuration, so the isolation is
+both current and version-explicit.

-system configuration and points global configuration at the null device before
