feat(P0a1): multi-namespace path resolver + config demotion + known_hosts flock + CA migration spec (v0.9 P0a1)
P0a1 — Re-architecture Foundation (path resolver + config demotion).
Path resolver (REQ-070, R-002):
- internal/paths/paths.go: 23 functions for the multi-namespace layout
(Root/ClusterDir/NamespaceDir/NS*/DefaultNamespace/CA/MasterKey/CacheDB/
Txn/Peers/KnownHosts/SSH/Server/Config). Honors $ORCA_HOME. 100% coverage.
- internal/certpaths/certpaths.go: refactored as thin shim delegating to
paths, preserving the v0.8 flat-layout API for backward compat during
the dual-write window (REQ-090). Package doc explains the v0.10-P14
migration plan. certpaths deleted after v0.10-P14. 100% coverage.
Config demotion (REQ-069, R-014):
- internal/config/markdown.go: minimal hand-rolled YAML frontmatter parser
(no new dep — yaml.v3 not in go.mod). Returns same *Config struct as HCL.
- internal/config/config.go: renamed Load body to LoadHCL (// Deprecated
per R-013), added dispatcher Load() routing on extension (.hcl->HCL,
.md->Markdown, .yaml->Markdown). Signature preserved so root.go unchanged.
- dispatch_test.go + markdown_test.go: 89.8% coverage on config package.
Known_hosts flock (REQ-063, deferred P1 from REVIEW_v0.8 A2):
- internal/security/flock.go: stdlib syscall.Flock advisory lock helper.
- internal/proxmox/bootstrap.go: TOFUHostKeyCallback capture + ResetHostKey
both acquire the flock before read-modify-write on known_hosts. Prevents
concurrent writers under v0.9 parallel SSH fan-out. 3 flock tests.
CA migration spec (grill C-07):
- .ciagent/CA_MIGRATION_SPEC_v0.9.md: Option A (preserve trust root,
RECOMMENDED) vs Option B (forced re-bootstrap). Pre-flight checks,
migration steps, rollback, post-migration invariants, spike plan.
Verification: build pass, 17/17 Go packages pass, 20/20 bats pass, gofmt
clean, go vet clean, verify-reqs 90 consistent. Coverage: paths 100%,
certpaths 100%, config 89.8%, emit covered.
