- Around line 27-35: Update the deterministic-context-cli job’s container image
to use the fully qualified docker.io/library/rust digest reference, matching the
existing CF11G_PROOF_CONTAINER value, so the execution image provenance is
explicit.

1. Cache failures lack diagnostics 📘 Rule violation ▣ Testability
The missing-archive and corrupt-digest CLI cases assert only exit code and empty stdout, without checking the emitted error type or message. This allows these distinct failure branches to regress to an incorrect or misleading diagnostic unnoticed.
Agent Prompt
## Issue description
The `commandf context` tests trigger missing-archive and corrupt-digest failures but do not verify their stderr diagnostics.
## Issue Context
PR Compliance 2717396 requires each distinct handler failure branch to assert the resulting status and error message or state. Add stable assertions for both cache failures while retaining the existing exit-code and empty-stdout checks.

2. Lock parse failures untested 📘 Rule violation ▣ Testability
The new context handler can fail while reading or parsing --lock, but no context CLI test supplies a missing lock or malformed lock bytes. Consequently, these input failure branches and their user-visible diagnostics are not covered.
Agent Prompt
## Issue description
The new `commandf context` lock read and parse failure branches have no command-level automated coverage.
## Issue Context
Existing context tests serialize valid lock objects, including the schema-v1 migration case; that does not execute `fs::read` failure or `Lockfile::from_slice` malformed-input failure. Add deterministic CLI tests that assert exit status, empty stdout, and stable stderr behavior for each branch.

3. Duplicate filenames misattribute edges 🐞 Bug ≡ Correctness
build_context_graph indexes inspected resources only by filename, so duplicate TAR entries overwrite each other while references are still extracted from every scanned entry. A package containing two different package/Foo.json entries can therefore emit references from one resource under the other resource's artifact hash, corrupting graph evidence.
Agent Prompt
## Issue description
The newly exposed context graph path can associate references with the wrong artifact when an archive contains duplicate normalized resource filenames.
## Issue Context
Resource scanning preserves duplicate filenames, but graph construction stores inspected resources in a filename-keyed map where later entries overwrite earlier entries. Fail closed on duplicate normalized resource paths, or preserve a one-to-one identity that includes the resource digest.

4. Lockfile read is unbounded 🐞 Bug ☼ Reliability
The new context command fully allocates the user-supplied lockfile with fs::read and then deserializes unconstrained vectors, maps, and strings. A large synthetic lockfile can exhaust memory and trigger substantial validation CPU before cache processing begins.
Agent Prompt
## Issue description
`commandf context` reads and parses lockfiles without a byte limit, allowing oversized input to consume unbounded memory and validation CPU.
## Issue Context
The CLI already provides `read_bounded_file`; introduce a deliberate maximum lockfile size and use that helper before `Lockfile::from_slice`. Add boundary tests for the exact limit and limit plus one.
