Problem: the hexagon's Phase 2 (plans/2026-08-15-hexagonal-architecture.md)
must give the use-cases-to-be their contract surface: driven-port
interfaces, test fakes, the secrets interface moved into core, and the
postgres package inside the adapters tree — before the first vertical
slice (Phase 3) can wire a composition root.
Change:
- internal/core/ports: full driven-port catalog per plan §3.3 —
repositories as transaction-scoped aggregates whose inputs carry
derived checks, audit, and events (§3.6), plus CommandExecutor,
TargetResolver, Checker, Secrets, EventPublisher, Provisioner.
Port-local payload types (Event, AuditEntry, CheckDef, KnowledgeEntry,
ExecResult) keep signatures off infrastructure; TypeTree aliases
internal/ontology (pure over domain) until checkdefaults is absorbed.
ReadModels intentionally not declared yet — it materializes with the
Phase 3 slice and grows as report handlers rewire.
- secrets.Backend is now an alias of ports.Secrets; implementations
(Infisical, SOPS, Manager) unchanged. mcp's local secretBackend
subset is deleted; tool constructors take ports.Secrets.
- internal/db → internal/adapters/postgres (mechanical import rewrite;
package identifier stays db until the Phase 3 repository split).
sqlc.yaml, Makefile, golangci exclusions, and docs follow the move;
make generate-check verified.
- internal/adapters/ssh: Executor implements ports.CommandExecutor over
the actuator dial pool + RunStreaming (10-min default timeout carried
over from the httpapi path).
- internal/adapters/remote: Resolver implements ports.TargetResolver
delegating to internal/remote (still pool-based; drops onto
ports.EntityRepository when repositories land in Phase 3 — documented
transitional import).
- internal/core/ports/portstest: importable fakes — in-memory
EntityRepo (with check-then-act SetState, side-effect recording),
RecordingExecutor, FakeChecker, SpyPublisher; port-satisfaction
guards; tests.
Risk: ports are declared ahead of implementations — signatures firm up
per phase as slices land (documented in the package doc); the
remote→postgres transitional import is explicit and dissolves in
Phase 3.
Verification: go vet, make test (race, 19 packages), generate-check,
golangci on core+adapters — 0 issues; full-repo baseline down
365→344.
Problem: the hexagonal-architecture plan (plans/2026-08-15-hexagonal-
architecture.md) needs its foundation — an accepted ADR, the target
directory tree, and machine-checked dependency rules — before any
service extraction starts. Also folds the four outstanding review
findings (F3.1/F5/F6/F7) into the plan: ObservationService owns the
bounded probe-concurrency contract (scheduler.go:133), Phase 9 gates
ExecutionService+PolicyService ≥ 90% with a gating-matrix test,
per-phase abort criteria, and the §3.2 internal/config note.
Change:
- docs/adr/0016-hexagonal-ports-adapters.md records context, decision,
and consequences of the ports & adapters migration.
- internal/domain → internal/core/domain (mechanical import rewrite,
20 files), new internal/core/{ports,app}, internal/adapters trees
with package docs.
- .golangci.yml: depguard rules for §3.1 (core purity, no agent-client
tech in core, nomos isolation — the nomos rules self-activate when
internal/nomos exists in Phase 8). Config migrated to golangci-lint
v2 format so it loads at all (the v1 config errored under v2, masked
by CI's advisory continue-on-error). Verified depguard fires on a
planted openai-go import in internal/core/app.
- CONTRIBUTING.md layout section now shows the core/adapters tree.
Risk: import path churn is mechanical and tests pass unchanged; the
lint config migration surfaces the pre-existing 400-issue baseline
(advisory in CI, unchanged policy) — new/moved packages lint clean.
Verification: go vet ./..., make test (race, core/domain at 100%
coverage), make generate-check, golangci-lint on internal/core/... and
internal/adapters/... — 0 issues; depguard violation probe confirmed.
R13 — on-client path reconciliation:
- AGENTS.md: 6 occurrences of /opt/homelab-context/ → /opt/homelab/
(sections 1, 2, 5, 7)
- .agents/NOMOS.md: 2 occurrences of /opt/homelab-context/ → /opt/homelab/
- CLIENTS.md already used /opt/homelab/ — now consistent across all docs.
The repo is still named 'homelab-context' (git remote), it just clones
to /opt/homelab/ on enrolled clients per CLIENTS.md.
R14 — golangci-lint/staticcheck/govulncheck tooling:
- .golangci.yml (new): config enabling govet, staticcheck, ineffassign,
unused, errcheck, gosimple, typecheck, misspell, revive. Excludes
generated code (internal/httpapi/gen/, internal/db/sqlcgen/) and
relaxes errcheck in test files.
- Makefile: split 'lint' target into vet, golangci, govulncheck subtargets.
Each checks if the tool is installed and prints install instructions
if not. 'make lint' runs all three.
- CI already had golangci-lint-action + govulncheck (both advisory);
the action auto-discovers .golangci.yml.
