Three defects surfaced during end-to-end RAG verification — the first two
block real chat usage, the third makes Linux CI flaky:
1. KB id detection — `IsKBID` was checking
`strings.HasPrefix(s, "kb_")`, but WeKnora generates KB ids as bare
UUIDs (internal/types/knowledge_base.go: `uuid.New().String()` stored
in a `varchar(36)` column). Real ids therefore fell through to the
name-resolution path:
$ weknora chat ... --kb a32a63ff-fb36-4874-bcaa-30f48570a694
Error: knowledge base not found: a32a63ff-...
Switched the discriminator to a UUID regex
(`^[0-9a-fA-F]{8}-…-[0-9a-fA-F]{12}$`). KB names are arbitrary
user-supplied strings, so the canonical 8-4-4-4-12 form is an
unambiguous signal. Mirrors gcloud `--project`'s id-vs-name detection.
2. SSE terminal-frame — the accumulator's `Append` was gating
finalization on `r.Done`, but the server's KnowledgeQAStream protocol
emits a leading `agent_query` frame with `done=true` to deliver
session + message metadata *before* the answer fragments arrive:
event: message
data: {"response_type":"agent_query","content":"","done":true,…}
event: message
data: {"response_type":"answer","content":"你好","done":false}
…
event: message
data: {"response_type":"complete","content":"","done":true}
The accumulator therefore flipped to `finished=true` on frame #1 and
discarded every subsequent answer fragment — `weknora chat … --json`
returned `answer: ""` even though the LLM reported completion_tokens
> 0. Fixed: terminate only on `response_type == complete`.
References still captured opportunistically (they may arrive on a
dedicated `references` event before the terminator).
3. doctor credential_storage CI isolation — the check probes the real
OS keyring via `secrets.NewBestEffortStore()`: present on macOS dev
machines → StatusOK; absent on Linux CI runners without libsecret /
Gnome-Keyring → StatusWarn ("falling back to file store"). That
host-dependence was leaking into two test classes that assumed
StatusOK:
* cmd/doctor/doctor_test.go: TestDoctor_AllOK and
TestDoctor_NoConfig_StillRunsCredentialStorage already had a
withCredStoreFactory seam but didn't use it. Added the pin.
* acceptance/contract/envelope_test.go: doctor.success_offline
and doctor.error_network golden cases. The contract test runs
through the cobra tree in-process and shares cmd/doctor's
package-level credStoreFactory var — but couldn't reach it
because the existing seam was unexported.
Fix: export `doctor.SetCredStoreFactoryForTest(fn) (restore func())`
for out-of-package tests; acceptance/contract/helpers_test.go adds
a TestMain that pins the factory to a MemStore-returning closure
for the whole suite (MemStore is neither *FileStore nor a real
keyring, so doctor's type-switch hits StatusOK). Production stays
at secrets.NewBestEffortStore — only the test hook is now reachable
from across packages.
Test fixtures and goldens that used the old `kb_xxx` literals or
`Done: true` terminators were rewritten to use real UUIDs and
`ResponseType: ResponseTypeComplete` respectively. Per-command --help
text and Long descriptions / Examples now show a UUID rather than
`kb_…` so users see the correct shape from the start. New
TestAccumulator_IgnoresAgentQueryDone pins the SSE terminator bug so
it can't regress.
Tests: 24 cli packages green on macOS dev + Linux/macOS/Windows CI
matrix. Verified end-to-end against a live WeKnora server: `weknora
chat "..." --kb <UUID> --no-stream --json` returns the full LLM answer
in the envelope, live token streaming in TTY mode works, and the
credential_storage check renders deterministic envelopes across hosts.
Discoverability gaps surfaced by the pre-PR review:
- New cli/README.md: install (build-from-source / pre-built once shipped)
+ 5-minute quickstart (auth login → kb list → link → doc upload →
chat) + multi-context walkthrough + JSON envelope shape + agent /
scripting integration overview + dev workflow. Points readers at
cli/AGENTS.md for the full operational contract.
- Top-level README.md: new "⌨️ Command-Line Interface" section between
Key Features and Getting Started, with a one-paragraph pitch + four
representative commands and links to cli/README.md and cli/AGENTS.md.
English README only this round; CN / JA / KO translations to follow
in v0.3 to match the existing four-language pattern.
- CHANGELOG.md [Unreleased] gets a "weknora CLI v0.2" bullet listing
the headline capabilities (10-command surface, project-link,
envelope, agent affordance, multi-context auth, doctor) and pointing
at cli/README.md.
- cli/AGENTS.md gains an "Architecture decisions" section documenting
ADR-3 (gh as primary mainstream north star + the four documented
deviations: link, chat/search, context use, doctor) and ADR-4
(Factory closures + narrow Service interfaces). The in-source
references (`(v0.2 ADR-3)`, `(per ADR-4)`) now point at committed
prose rather than dangling.
