+## v0.7 Scope Summary — Hardening & Completion
+
+v0.7 is a 4-execution-phase **NFR milestone** that closes out gaps
+surfaced by the v0.7 IDEATE stage: an unreachable command tree, a
+missing config file layer, low test coverage in core packages, and the
+long-deferred pprof endpoint. The engine functionality from v0.1–v0.6
+is unchanged; this milestone is purely about **correctness, coverage,
+and operability**:
+
+- **P01 — Register `orca cert` command tree + cert_repo tests.** The
+  `internal/cli/cert.go` command (`cert ca-init`, `cert gen`, `cert
+  show`, `cert renew`, `cert fingerprint`) is fully implemented but
+  never wired into `rootCmd`. This phase adds the missing
+  `rootCmd.AddCommand(newCertCmd(...))` and adds the missing
+  `internal/store/cert_repo_test.go`. Covers REQ-053.
+- **P02 — HCL config file parsing (`config.hcl`).** D-009 specified
+  `~/.orca/config.hcl` and `/etc/orca/orca.hcl` as config locations,
+  but no HCL config-file parser exists — the CLI relies entirely on
+  flags and env vars. This phase adds a minimal `internal/config`
+  package that loads `config.hcl` (keys: `db_path`, `listen_addr`,
+  `ca_path`, `server_cert_path`, `server_key_path`, `node_capacity`),
+  merges with env/flag overrides (flag > env > file > default), and
+  surfaces it via `--config` flag on the root command. Covers
+  REQ-054.
+- **P03 — Test coverage uplift.** Adds tests for the lowest-coverage
+  packages: `internal/engine` (executor, dispatcher, peer — currently
+  8.3%), `internal/transport` (mtls, dispatch, handshake_log —
+  currently 26.3%), `internal/proxmox` (bootstrap SSH path —
+  currently 5.1%), and `internal/audit` (no tests). Target: every
+  package ≥ 50% coverage. Covers REQ-055.
+- **P04 — `--pprof` opt-in on `orca daemon`.** Adds the long-deferred
+  I-308 pprof endpoint behind an opt-in `--pprof <addr>` flag (default
+  disabled). `net/http/pprof` mounted on a separate mux so it never
+  touches the mTLS daemon listener. Covers REQ-056.
+- **P05 — Final review + ship + audit.** Milestone release.
+
+The vision ("minimalist, offline-first, CLI-first orchestration
+engine") is unchanged. v0.7 is a hardening milestone, not a direction
+change. Milestone type: NFR (all phases are fix/test/chore); the final
+phase's progressive patch IS the deliverable per `run.md` versioning
+logic. Tags run on the v0.5.x patch line: `v0.5.5` (P0) … `v0.5.9` (P05
+= milestone release).
