feat(P0a2): namespace CRUD + inheritance engine (REQ-082)
P0a2 — Namespace inheritance resolver + orca ns CLI subcommands.
Resolver (REQ-082, internal/ns/resolve.go):
- Pure Resolve() function: DFS post-order chain assembly (most-specific
first, _defaults implicit last D-185). Child-wins-scalar env merge, de-duped
union constraints. Cycle detection with readable cycle path. Missing-parent
+ missing-_defaults + misordering (['_defaults','x']) rejection. Opt-out
impossible (D-187). 89.6% coverage.
Parser (internal/ns/parse.go):
- ParseNSMd: hand-rolled YAML frontmatter (no yaml.v3 dep). Validates
kind:Namespace + name, parses parents flow-array, inherits_env/secrets.
- ParseNSMdDir: walks root/*/ns.md, skips cluster/, requires _defaults.
CLI (internal/cli/ns.go, D-176):
- orca ns list/create/delete/inspect/validate. Inspect + validate use the
resolver. Create refuses _defaults/cluster; delete refuses _defaults +
non-empty namespaces. JSON output support. 85.2% coverage.
- Registered on rootCmd.
Tests: resolve_test.go (11 tests), parse_test.go (14 tests), ns_test.go
(21 tests). 18 packages pass, 20 bats pass, gofmt clean, verify-reqs 90
consistent.
