/speckit-plan output for 004-product-knowledge: technical context and
constitution gate check (all PASS), Phase 0 research (6 decisions:
new-row-per-version instead of in-place overwrite to satisfy history
retention, conditional-update-then-insert concurrency reusing
003-ticketing's optimistic-locking pattern, structured (non-semantic)
filtered retrieval per doc 11 gap B1, known-issue lookup by error
code, creating the ai-support module group for the first time with
only its knowledge submodule populated, and admin auth consistent
with prior features), Phase 1 data model (KnowledgeEntry/ErrorCode/
KnownIssue/Runbook, refining doc 06's conceptual schema with an
explicit version-history mechanism), the admin CRUD + retrieval
contract, and a 6-scenario quickstart.
