• Operator edits are never merged, so a replica holding a stale config must learn it lost instead of silently replacing a newer one. Checking each write against the revision it last read surfaces that as a conflict.

Walkthrough

The change adds a NATS-backed ConfigStore for config.yaml. It tracks revisions across reads and writes, normalizes line endings, and returns conflicts when writes use a stale revision.

Changes

Configuration storage

Layer / File(s)	Summary
ConfigStore reads, writes, and validation internal/store/natsstore/configstore.go, internal/store/natsstore/configstore_test.go	ConfigStore reads and writes config.yaml through a KV, tracks revisions, and normalizes line endings. Tests cover not-found results, revision updates, stale-write and first-write conflicts, and empty configuration values.

Explanation

The title names the main change: adding a ConfigStore that saves the config file in the NATS config bucket (natsstore). It is concise, specific, and matches the raw summary, which adds ConfigStore storing config.yaml in a KV.

Full details: Description check

Explanation

The description states that operator edits are never merged and that a replica holding stale config must learn it lost. It says checking each write against the last-read revision surfaces this as a conflict. This matches the changeset, which adds a ConfigStore whose Write uses the remembered revision for optimistic concurrency and returns conflicts for stale writes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

_{A rabbit reads the config with care
Then writes new lines in tidy rows
A revision marks each change
Stale writes meet a conflict
Empty pages still can be saved
And carrots celebrate the flow}
