Two issues surfaced during the post-P3-5 manual smoke test against a
six-document workspace:
1. --config flag was silently ignored. kb-cli read cli.config only
while building SourceScope inside the Ingest arm, then called
kb_app::ingest(scope, summary_only) which internally re-loads
Config::load(None) — falling back to ~/.config/kb/config.toml
regardless of what the user passed. Same pattern in search,
list, inspect, doctor. Users had to rely on KB_* env vars to
point at a non-default config.
2. Search output collapsed RRF hybrid scores to "0.02" because
`{:.2}` truncated the (0, 0.033]-bounded fused score, and
chunks from the same document showed up as identical lines
("3. 0.02 arch/rag-architecture.md") since heading_path was
never printed.
Fix:
- kb-app: doctor/ingest/search/list/inspect already had
*_with_config(Config, ...) seams introduced for integration tests
(#[doc(hidden)] pub). Repurpose them as the official "config-explicit"
API — kb-cli now builds the Config once via
Config::load(cli.config.as_deref()) at the top of every subcommand
and threads it into the *_with_config variant. Module doc-comment
updated to reflect three callers (CLI --config, integration tests,
TUI session) instead of "test-only seam".
- kb-app: doctor() rewritten as doctor_with_config_path(Option<&Path>)
that respects an explicit path. config_loaded probe now reports the
actual path checked, returning a clear hard error if --config points
at a non-existent or malformed file (defaults would silently mask
user intent). data_dir_writable resolves storage.data_dir from the
loaded config (with env overrides applied via Config::apply_env) so
--config users see their custom paths reflected. Original doctor()
signature kept as a None-passing wrapper.
- kb-cli: ingest/search/list/inspect/doctor each call the
*_with_config* companion. Search printer switches to {:.4} score
formatting (RRF hybrid range bounded by ~2/k_rrf ≈ 0.033 at k_rrf=60
default) and appends `> head1 / head2` when heading_path is non-
empty so chunks from the same document are visually distinguishable.
Verified manually:
- `kb --config /tmp/kb-smoke/config.toml doctor` reports the
custom config path + custom data_dir, not the XDG defaults.
- `kb --config /tmp/kb-smoke/config.toml search "..." --mode hybrid`
returns hits with distinct 4-digit scores and heading paths
("rust/ownership.md > Rust 소유권 모델 / Borrow checker").
