Summary

Adds integration test coverage for minimal::diag::cmd_bug (issue #1389), which previously had zero whole-function execution coverage.

The tests drive cmd_bug end-to-end with --no-guest (no daemon contact) and assert the observable bundle contract:

  • a valid manifest.json (schema_version 1, non-zero duration, non-empty collected list)
  • host-side collectors (host/system.json, host/terminal.json, host/env.json, host/dirs.txt)
  • project attribution (project/project.json)
  • log tail capture and --log-tail-bytes capping (marked tail-capped)
  • config redaction (a token value never appears in the bundle)
  • provider file collection and per-provider guest skip records
  • state listing, loadout definitions, and mesh-enrolment handling

Verification

  • cargo build --workspace --all-targets — passes
  • cargo test -p minimal diag:: — 34 passed, 0 failed
  • cargo fmt --all — clean

Two pre-existing failures in crates/checkouts (git-clone tests) are unrelated to this change.

Closes #1389

Summary by CodeRabbit

  • Tests
    • Expanded diagnostic archive checks to verify collected host information, skipped provider and guest records, state listings, mesh-enrolment data, and redacted configuration details.
    • Improved log-tail coverage by verifying that captured excerpts contain the expected tail content and respect the configured size limit.
    • Refined mesh-enrolment checks to distinguish relevant errors from unrelated manifest errors.
  • User-facing changes
    • No changes to product behavior are included in this update.

Add integration tests exercising cmd_bug end-to-end with --no-guest:
manifest validity, host collectors, log tail capture and capping, config
redaction, provider files, state listing, and mesh-enrolment handling.

📝 Walkthrough

Walkthrough

Diagnostic tests refine assertions for collected data and capped log tails. The mesh-enrolment test now checks for errors specific to mesh-enrolment instead of requiring the manifest error list to be empty.

Changes

Diagnostic test assertions

Layer / File(s) Summary
Collection and log-tail assertions
crates/minimal/src/diag/mod.rs
Checks that collected data is nonempty. Uses distinct head and tail bytes to verify that the captured 1024 log bytes come from the tail.
Mesh-enrolment error filtering
crates/minimal/src/diag/mod.rs
Fails the assertion when a manifest error mentions mesh-enrolment, while allowing unrelated manifest errors.

Tail-end T bytes fill the log there.

Mesh errors stand apart from the rest.

- Around line 751-753: Update the tail-cap test fixture to use distinct bytes
for the file’s first and last 1024-byte segments, then assert the captured log
contains the tail segment’s bytes. Keep the existing length check so the test
verifies both the cap and that the read comes from the end of the file.
- Around line 941-947: Update the assertion on manifest["errors"] to fail only
when an error mentions mesh-enrolment; ignore errors from unrelated host
collectors while preserving the existing manifest parsing and diagnostic
context.

Round 1 of 10 is on this pull request.

branch chore/coverage-cmd-bug-45718caa7a3c450f

Updated 2026-09-24T21:22:57.493Z.

Address the review findings on #1684 and the clippy failure:

- the tail-cap fixture now uses distinct head/tail bytes, so the
  assertion proves the capture reads from the end of the file (a head
  read of the old uniform fixture would have passed)
- the missing-mesh-enrolment test scopes its error assertion to
  entries mentioning mesh-enrolment instead of the manifest's whole
  error list, which is fed by environment-dependent host collectors
- assert non-emptiness with is_empty(), satisfying clippy::len_zero
  (-D warnings), the
8000
 CI clippy lane's only error

Round 1 of 10 on a /revise note, pushed as e94328af5427.

No test: line was run.

Review threads the coder judged:

  • 👍 valid — crates/minimal/src/diag/mod.rs: fixture now writes 1024 'H' bytes then 1024 'T' bytes and asserts the captured log is all 'T', so a head read fails the length/content assertion it previously slipped past
  • 👍 valid — crates/minimal/src/diag/mod.rs:957: error assertion scoped to entries mentioning 'mesh-enrolment'; unrelated host collectors' errors no longer fail this test, and a mesh-enrolment regression surfacing via the config collector's error chain still would

At this branch, PR #1684's failing checks are addressed: the clippy lane's only error (clippy::len_zero in the new cmd_bug test module) is fixed, the tail-cap test now uses distinct 'H' head / 'T' tail bytes so its all-'T' assertion genuinely proves the capture reads the last 1024 bytes rather than the first, and the missing-mesh-enrolment test asserts only that no error mentions mesh-enrolment instead of demanding an empty manifest-wide error list. cargo test -p minimal diag:: passes 34/34, fmt and clippy are clean.

Notes from the agent: Both review threads were judged valid against the code and fixed: (1) the uniform b'A' fixture could not distinguish a head read from a tail read, so it now writes 1024 'H' bytes followed by 1024 'T' bytes and asserts all-'T' (add_file_tail seeks to End-cap, confirmed in crates/diagnostics/src/bundle.rs:180); (2) errors.is_empty() was hostage to environment-dependent host collectors (net/procs/power read the live system), so the assertion is scoped to error entries mentioning 'mesh-enrolment' — the mesh collector itself only ever records a skip, never an error, for enrolment trouble. The failing ci-success/clippy checks traced to a single clippy::len_zero error in the new test module; clippy was verified with the CI command scoped to the touched crate (-p minimal --all-targets --locked -- -D warnings) rather than the full --workspace run, since this PR changes nothing outside that crate and main's workspace clippy was green. The two pre-existing crates/checkouts git-clone test failures mentioned in the PR body were not run or reproduced here; they are outside this PR's change set.

#1684 landed thirteen BugArgs literals in the diag unit tests; merging
main brought them onto this branch without the two fields it adds, so
the lib test target no longer compiled (E0063). Set them the way the
tests/bug.rs helper does: no upload, an empty portal.
