Roadmap: Orca

Milestone v0.1: Foundation — COMPLETE

• Phase 0: Project Initialization & Specification
• Phase 1: Core CLI Skeleton & Command Parsing
• Phase 2: Basic Node Management (Join/Leave)
• Phase 3: Simple Task Execution Engine
• Phase 4: Local State Persistence
• Phase 5: Basic Health Checking
• Phase 6: CoreCI Full Release Flow

Tagged v0.2.0 (next-minor per feature-milestone promotion rule).

Deferred to v0.2 (out of scope for v0.1)

• Multi-node scheduling (D-004 decision: single-node only in v0.1)
• mTLS for inter-node communication (REQ-011, REQ-023)
• gosec + govulncheck in CI pipeline (REQ-014)
• iter.Seq streaming job lists (REQ-022)
• Frontend / devops personas (no web UI; CoreCI handles release)

Milestone v0.2: Networking, Observability, Security Hardening — COMPLETE (merged to main via v0.3)

Scope: extend v0.1 with secure cross-node transport, multi-node scheduling, richer CI security scanning, and streaming I/O.

• Phase 8: mTLS handshake + internal CA with CSR join (Wave 1) — shipped v0.2.1
• Phase 9: Multi-node scheduling & job dispatch (Wave 1) — shipped v0.2.2
• Phase 10: gosec + govulncheck + gitleaks in CI (Wave 2) — shipped v0.2.3
• Phase 11: iter.Seq streaming job/node lists (Wave 2) — completed in v0.3 P01 (shipped v0.3.1)

Milestone tag: v0.4.0 (shipped — v0.2 work merged to main via v0.3 milestone).

Per-phase tags: v0.2.1 (P01), v0.2.2 (P02), v0.2.3 (P03) — all shipped.

Milestone v0.3: Scheduling & Streaming Completion — COMPLETE

Scope: complete the two work items deferred from v0.2 that were not already shipped in P08-P10. A re-init SPECIFY codebase audit confirmed that REQ-014/027/028/029/031/037/039/040 all shipped in P08-P10 despite stale REQUIREMENTS.md marking them Pending. The remaining work is lean:

• Phase 0: Pre-execution (specify → clarify → research → plan → grill) — shipped v0.3.0
• Phase 1: iter.Seq streaming for --watch flags (REQ-022, REQ-030) — shipped v0.3.1
• Phase 2: orca doctor network + db full implementation (REQ-032 completion) — shipped v0.3.2
• Phase 3: Final review + ship + audit (milestone release) — shipped v0.3.3

Milestone tag: v0.4.0 (next-minor per feature-milestone promotion rule).

Per-phase tags: v0.3.0 (P0), v0.3.1 (P01), v0.3.2 (P02), v0.3.3 (P03 final = milestone release). Per .ciagent/RELEASE_POLICY.md, every phase tag produces a Gitea release.

Per-phase REQ coverage

• P01 — iter.Seq streaming for --watch flags

  • REQ-022 (iter.Seq for streaming job lists, Go 1.25+)
  • REQ-030 (--watch output format mode: table default vs streaming JSON per event)
  • Applies to both orca job list --watch and orca node list --watch (D-024, per ARCHITECTURE.md CLI layer + D-017)

• P02 — orca doctor network + db full implementation

  • REQ-032 (completion: network reachability via mTLS /healthz probe, db integrity via PRAGMA integrity_check + migration version)
  • Replaces NetworkStub and DBStub from v0.2 P01

v0.3 is a completion milestone, not a direction change

The vision ("minimalist, offline-first, CLI-first orchestration engine") is unchanged. v0.3 closes out the v0.2 deferrals and merges the accumulated v0.2 work to main.

Milestone v0.5: Distribution — COMPLETE

Scope: make Orca installable, distributable, and containerized. The engine functionality from v0.1–v0.3 is unchanged; this milestone is purely about delivery surface.

• Phase 0: Pre-execution (specify → clarify → research → plan) — shipped v0.4.1 (+ repo public)
• Phase 1: Namespace unification (ORCA_HOME + --system) (REQ-041, REQ-042) — shipped v0.4.2
• Phase 2: install.sh + in-place update + README quickstart (REQ-043, REQ-044) — shipped v0.4.3
• Phase 3: Docker release (Dockerfile + Gitea container registry) (REQ-046) — shipped v0.4.4
• Phase 4: Final review + ship + audit (milestone release) — shipped v0.4.5

Operational prerequisite (P0 ship): repo + org visibility flipped to public (REQ-045) — unauth releases API + asset download + docker pull all verified HTTP 200.

Milestone tag: v0.4.5 (final phase patch = milestone release per feature-milestone promotion rule). Per-phase tags: v0.4.1…v0.4.5.

Milestone v0.6: Node Bootstrap & Proxmox

Milestone v0.6: Node Bootstrap & Proxmox — COMPLETE

Scope: make orca init produce a fully working single-node cluster (CA + server cert + DB + localhost node registered with auto-detected OS), and add Proxmox 8 & 9 as a first-class remote node type joined over SSH with least-privilege role delegation.

• Phase 0: Pre-execution (specify → clarify → research → plan → grill) — tag v0.5.0
• Phase 1: orca init full bootstrap + localhost node + schema 0006 (REQ-047, REQ-048, REQ-049) — tag v0.5.1
• Phase 2: Proxmox SSH join + OrcaOperator role + sudoers allowlist (REQ-050, REQ-051) — tag v0.5.2
• Phase 3: doctor os + doctor proxmox SSH probe + audit logging (REQ-052) — tag v0.5.3
• Phase 4: Final review + ship + audit (milestone release) — tag v0.5.4

Milestone type: feature (P1/P2/P3 ship feat phases). Milestone tag: v0.5.4 (final phase patch = milestone release per feature-milestone promotion rule). Per-phase tags: v0.5.0…v0.5.4.

Tags run on the previous minor's patch line (v0.5.x) per branch-strategy.md. The milestone branch label uses the milestone number (milestone/v0.6-node-bootstrap-proxmox); no separate minor tag is created.

Milestone v0.7: Hardening & Completion — COMPLETE

Scope: NFR milestone closing 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.

• Phase 0: Pre-execution (specify → clarify → research → ideate → plan) — tag v0.6.0 (shipped)
• Phase 1: Register orca cert command tree + cert_repo tests (REQ-053) — tag v0.6.1 (shipped)
• Phase 2: HCL config file parsing — internal/config package (REQ-054) — tag v0.6.2 (shipped)
• Phase 3: Test coverage uplift — engine/transport/proxmox/audit ≥ 50% (REQ-055) — tag v0.6.3 (shipped)
• Phase 4: --pprof opt-in on orca daemon (REQ-056) — tag v0.6.4 (shipped)
• Phase 5: Final review + ship + audit (milestone release) — tag v0.6.5 (shipped)

Milestone type: NFR (all phases are fix/test/chore; no feat phases). Milestone tag: v0.6.5 (final phase patch = milestone release per NFR-milestone progressive-patch rule). Per-phase tags: v0.6.0…v0.6.5. Tags run on the previous minor's patch line (v0.6.x) per branch-strategy.md. The milestone branch label uses the milestone number (milestone/v0.7-hardening-completion); no separate minor tag.

Milestone v0.8: Coverage & Trust Hardening — COMPLETE

Scope: continue the v0.7 hardening theme. v0.7 P03's ≥ 50% floor left six packages still under 50% (engine 8.3%, proxmox 5.1%, cli 27.6%, transport 26.3%, store 46.7%, jobspec 47.6%) and three packages with no tests at all (internal/audit, internal/certpaths, cmd/orca). v0.8 also closes the two SSH-trust "future enhancement" hooks deferred in v0.6 (D-035 --host-key-fingerprint pre-pin, RESEARCH_v0.6 §80 orca node key-reset) and adds a requirements-hygiene gate to prevent the stale-REQ-status drift seen after v0.7 ship.

• Phase 0: Pre-execution (specify → clarify → research → plan → grill) — tag v0.7.0 (shipped)
• Phase 1: Test coverage uplift round 2 — 6 packages to ≥ 70%, 3 zero-test packages to first tests (REQ-057) — tag v0.7.1 (shipped)
• Phase 2: SSH trust hardening — --host-key-fingerprint pre-pin + orca node key-reset + TOFU bugfix + HostKeyFingerprint population (REQ-058, REQ-059) — tag v0.7.2 (shipped)
• Phase 3: Requirements-hygiene gate — make verify-reqs + verify assertion (REQ-060) — tag v0.7.3 (shipped)
• Phase 4: Final review + ship + audit (milestone release) — tag v0.7.4 (shipped)

Milestone type: NFR (P01 test, P02 chore on trust surface per D-043, P03 chore, P04 docs/review). Final phase patch IS the milestone release per NFR-milestone progressive-patch rule. Per-phase tags: v0.7.0…v0.7.4. Tags run on the previous minor's patch line (v0.7.x) per branch-strategy.md. The milestone branch label uses the milestone number (milestone/v0.8-coverage-trust-hardening); no separate minor tag.

Per-phase REQ coverage

• P01 — Coverage uplift round 2

  • REQ-057 (raise internal/engine, internal/proxmox, internal/cli, internal/transport, internal/store, internal/jobspec to ≥ 70%; add first tests for internal/audit, internal/certpaths, cmd/orca)

• P02 — SSH trust hardening

  • REQ-058 (--host-key-fingerprint <sha256> pre-pin flag on orca node join --type proxmox; fail fast on mismatch; supersedes TOFU for pre-pinned deployments)
  • REQ-059 (orca node key-reset <node> clears persisted SSH host key so next doctor proxmox/dispatch re-pins via TOFU or --host-key-fingerprint)

• P03 — Requirements-hygiene gate

  • REQ-060 (make verify-reqs target + verify-stage assertion: every REQ Complete in ROADMAP.md has matching Complete row in REQUIREMENTS.md; enforced in CI validate pipeline)

v0.8 is a continuation milestone, not a direction change

The vision ("minimalist, offline-first, CLI-first orchestration engine") is unchanged. v0.8 closes the coverage debt left by v0.7's 50% floor and the trust-surface gaps explicitly deferred in v0.6.

Milestone v0.9: Re-architecture Foundation & Workloads — COMPLETE

Scope: This milestone SUPERSPEDES the shipped v0.1–v0.8 architecture per the adopted PRD (.ciagent/PRD_v0.9.md). The re-architecture is justified on six grounds recorded in the PROJECT.md Supersession Table: (1) the v0.8 daemon model is operationally failing, (2) step-ca is externally mandated, (3) multi-tenancy is a hard product requirement, (4) WASM is a hard workload requirement, (5) SSH-push is the only viable deployment target, (6) vision correction. The 16 load-bearing rules (R-001…R-016) are invariants. The ci-griller reviewed the re-architecture adversarially; the user overrode the Re-architecture Justification REPLAN with the six-part evidence basis; the 19 binding conditions (C-01..C-19) and 10 phase challenges (PC-01..PC-10) from GRILL_v0.9.md are adopted as execution gates. 30 net-new requirements (REQ-061..REQ-090) derive from IDEATION_v0.9.md.

Milestone type: feature (P01..P10 ship feat phases; P00/P0X are chore/docs).

• Phase 0: Pre-execution (specify → clarify → research → ideate → plan → grill) — tag v0.8.0 (shipped; this is the phase you are reading)
• Phase P00: Deprecation sweep + bash tooling gate + render contract + doc banners (REQ-068,072,088,089,090; gates C-03,C-05,C-06,C-15..C-18) — tag v0.8.1 ✓
• Phase P0a1: Multi-namespace path resolver + config demotion + known_hosts flock (REQ-063,069,070,071; gate C-07) — tag v0.8.2 ✓
• Phase P0a2: Namespace CRUD + inheritance engine (REQ-082) — tag v0.8.3 ✓
• Phase P0b: Markdown jobspec parser + dispatcher + fuzz (REQ-064,067) — tag v0.8.4 ✓
• Phase P0c: Job/Service/DaemonSet schemas + emitter interface (REQ-074) — tag v0.8.5 ✓
• Phase P01: SSH-push transport (REQ-073) — tag v0.8.6 ✓
• Phase P02: Service block + Traefik emitter (REQ-077; gate C-10) — tag v0.8.7 ✓
• Phase P03/P04/P08: Update stanza + lifecycle hooks + socket plumbing (combined) — tag v0.8.8 ✓
• Phase P05: CLI-side scheduler + CEL constraints (REQ-083) — tag v0.8.9 ✓
• Phase P06: Task groups (multi-process services) — tag v0.8.10 ✓
• Phase P07a/b/c: Runtime abstraction — 5 backends (REQ-078; gate C-01) — tag v0.8.11 ✓
• Phase P09: Syncthing storage replication (REQ-081; gates C-02,C-14) — tag v0.8.12 ✓
• Phase P10: Lead rules + step-ca (REQ-076) — tag v0.8.13 ✓
• Phase P0X: Ship + audit (REQ-062,068) — tag v0.8.14 ✓

Milestone tag: v0.8.15 (final phase patch = milestone release per feature-milestone progressive-patch rule). Per-phase tags: v0.8.1…v0.8.14. P03/P04/P08 were combined into one phase; P07a/b/c were combined into one phase. Actual execution: 14 tagged phases. Tags run on the previous minor's patch line (v0.8.x) per branch-strategy.md. The milestone branch label uses the milestone number (milestone/v0.9-rearchitecture); no separate minor tag.

Per-phase REQ coverage (v0.9)

• P00 — Deprecation/migration/test-infra/persona/docs foundation (REQ-072, REQ-085, REQ-088, REQ-089, REQ-090)
• P0a1 — Path resolver + config demotion + known_hosts flock (REQ-063, REQ-069, REQ-070, REQ-071)
• P0a2 — Namespace inheritance resolver (REQ-082)
• P0b — Markdown parser + adapter + fuzz (REQ-064, REQ-067)
• P0c — Schemas + emitter interface (REQ-074)
• P01 — SSH-push transport (REQ-073)
• P02 — Service + Traefik emitter (REQ-077)
• P05 — CLI-side scheduler (REQ-083)
• P07a/b/c — Runtime abstraction (REQ-078) + step-ca integration (REQ-076)
• P09 — Syncthing replication (REQ-081)
• P0X — Coverage gate (REQ-062) + deprecation warnings (REQ-068)

v0.9 is a DIRECTION CHANGE — first in the project's history

Every prior milestone (v0.1–v0.8) explicitly said "the vision is unchanged; this milestone is not a direction change." v0.9 is the first milestone that reverses the vision's anti-patterns (daemon-on-every-node, internal CA, HCL-canonical, single-namespace, no-container-runtime, no-SPIFFE). The reversals are justified by the six-part evidence basis recorded in the PROJECT.md Supersession Table.

Milestone v0.10: Docs & Install Hardening — COMPLETE

Scope: close the documentation gap left by the v0.9 re-architecture and fix the release/install pipeline bug that caused install.sh to resolve to v0.4.5 instead of the latest release. The v0.9 re-architecture shipped a complete CLI surface (markdown jobspec, orca ns, orca node capacity, CLI-side scheduler, emitters, Traefik ingress) but no operator-facing reference documentation. This milestone ships that documentation plus a worked full-stack example with ingress configured, and hardens the release pipeline so every Gitea release carries a Linux binary asset.

Milestone type: feature (P1 ships fix phases; P2/P3/P4 ship docs phases; at least one non-docs phase makes this a feature milestone per the versioning logic).

• Phase 0: Pre-execution (specify → clarify → research → ideate → plan → grill) — tag v0.9.0
• Phase P1: release.sh + install.sh fix (REQ-097, REQ-098) — tag v0.9.1
• Phase P2: docs/cli.md + docs/jobspec.md + docs/ingress.md (REQ-091, REQ-092, REQ-093) — tag v0.9.2
• Phase P3: examples/full-stack/ (REQ-094) — tag v0.9.3
• Phase P4: README.md + docs/namespace.md refresh (REQ-095, REQ-096) — tag v0.9.4
• Phase P5: Final review + ship + audit (milestone release) — tag v0.9.5 = v0.10.0 milestone release

Milestone tag: v0.9.5 (final phase patch = milestone release per feature-milestone progressive-patch rule). Per-phase tags: v0.9.0…v0.9.5. Tags run on the previous minor's patch line (v0.9.x) per branch-strategy.md. The milestone branch label uses the milestone number (milestone/v0.10-docs-cli-examples); no separate minor tag.

Per-phase REQ coverage (v0.10 docs milestone)

• P1 — release.sh cross-build + asset verification (REQ-097); install.sh fallback walk (REQ-098)
• P2 — CLI reference (REQ-091); jobspec reference (REQ-092); ingress guide (REQ-093)
• P3 — full-stack examples (REQ-094)
• P4 — README refresh (REQ-095); namespace.md v0.9 layout (REQ-096)

Root cause of the v0.4.5 install (documented in RESEARCH_v0.10.md)

The v0.8.x releases (v0.8.0–v0.8.15) shipped with zero binary assets attached to their Gitea releases. install.sh resolves "latest" → v0.8.15, looks for orca-v0.8.15-linux-amd64.tar.gz, finds nothing, and errors out. The v0.4.5 install came from an earlier run or a pinned --version. The fix is forward: release.sh cross-builds amd64 and verifies the asset post-create; install.sh walks backward through releases if the latest lacks the asset.

Milestone v0.11: Production Hardening

Scope: ship a cluster that operators can run. Builds on the v0.9 re-architecture foundation with the production-grade subsystems: secrets, transactions, ACL/SPIFFE, backup/restore, drain, recovery, and the v0.8→v1.0 migration. Phase 0 adopts 4 new load-bearing rules (R-017…R-020) and 23 new decisions (D-215…D-237) from 5 research docs covering ingress hardening, drift detection, platform-engineer positioning, strategic framing, and the systemd Path unit implementation. No new phases added; scope is folded into existing phases per operator decisions Q2=C (add 5 CLI commands), Q3=A (fold ingress into P15.5).

Milestone type: feature (multiple feat phases).

• Phase 0: Pre-execution (specify → clarify → research → plan → grill) — tag v0.10.0
• Phase P00: CLI cache layer (REQ-062 cache floor; R-008) — tag v0.10.1
• Phase P01: Metrics endpoint (hand-rolled text exposition) — tag v0.10.2
• Phase P01.5: SPIFFE SVID minting spike (REQ-076; gate C-08 — if spike fails, fall back to mTLS identity) — tag v0.10.3
• Phase P02: ACL (SPIFFE + token identities) — tag v0.10.4
• Phase P03: Secrets subsystem (REQ-080; gate C-19 threat model) — tag v0.10.5

• Phase P07: Recovery (orca restore) — tag v0.10.9
• Phase P08: Integration tests — expand hermetic harness (REQ-087) + drift-detection integration tests (auto-remediation, NFS fallback, cooldown, secret exclusion) — tag v0.10.10
• Phase P09: Collector + aggregator (opt-in; gates C-11, C-12, C-14) + drift-event aggregation extension (REQ-107, D-237) — tag v0.10.11
• Phase P10: Transactional plane (REQ-075, REQ-079; gate C-09) + drift detection (R-018/R-019/R-020, REQ-103..REQ-113; orca drift CLI, systemd Path unit emitter, orca-drift-notify.sh, orca-remediate.sh, cadence config, --force+per-ns gate, orca system user, NFS detection) — tag v0.10.12
• Phase P11: orca job lint (REQ-084) — tag v0.10.13
• Phase P12: orca job verify (dry-run txn through lead) — tag v0.10.14
• Phase P13: orca ns subcommands (full surface) + deprecation warnings (REQ-068) — tag v0.10.15
• Phase P14a: v0.8→v1.0 data migration (REQ-066; gate C-07) + orca upgrade --to-vX (REQ-115, thin wrapper, handles R-017 binding cutover) — tag v0.10.16
• Phase P14b: Daemon cutover + running-allocation adoption + orca cluster rotate-lead (REQ-114) — tag v0.10.17
• Phase P14c: Mixed-version tolerance + no-orca-on-server enforcement (REQ-065, REQ-086; implements C-13) — tag v0.10.18
• Phase P15: README quickstart (REQ-089; Nomad-inspired framing per Q5=A, honest-trade-offs table from research doc 3) — tag v0.10.19
• Phase P15.5: Threat model + security review (gate C-19) + ingress hybrid (R-017; nft emitter REQ-099, Traefik binding REQ-100, orca doctor nft REQ-101, orca nft CLI REQ-102) + orca doctor mTLS (REQ-118) — tag v0.10.20
• Phase P16: Final review + ship + audit — v0.11.0 milestone release — tag v0.10.21 (v1.0.0 cut separately after UAT sign-off)

Milestone tag: v0.11.0 (the v0.11 milestone release tag; v1.0.0 is UAT-gated and cut separately after v0.11 completion per operator decision — the v1.0.0 tag marks production-ready sign-off, not a separate milestone). Per-phase patches run on the v0.10.x line per branch-strategy.md. Per-phase tags: v0.10.0…v0.10.21.

Per-phase REQ coverage (v0.11)

• P15.5 — Threat model (C-19) + ingress hybrid (R-017; REQ-099..REQ-102) + orca doctor mTLS (REQ-118)

New load-bearing rules adopted in Phase 0

• R-017 — Ingress hybrid: nft DNAT → Traefik on 127.0.0.1:8443; opt-out via --public-binding; service { ingress: native } per-workload opt-in
• R-018 — Drift cadence: default 60s; critical 5s + systemd Path units; standard 30s
• R-019 — Drift detector is a BACKSTOP; primary = systemd/Traefik/step-ca/Syncthing
• R-020 — Hard gate: applier refuses txns on pre-flight drift; --force + per-ns scoping override

Risk register (from grill + research, for ongoing monitoring)

• step-ca single-instance SPOF (mitigation: C-12 doc; v1.x HA via systemd failover)
• master.key passphrase-less 0600 (mitigation: C-19 threat model; consider OS keyring in v1.x)
• wasmtime CGO breaks cross-compile (mitigation: C-01 spike; fallback to podman/process primary)
• bash control plane drift (mitigation: C-15..C-18 render-format contract + bats gate)
• daemon cutover orphans running allocs (mitigation: P14b split; test adoption)
• 27→35+ phase scope (mitigation: C-04 resolved — operator accepted 40 phases; v0.11 stays at 23 phases with scope folded in, no new phases)
• R-020 deadlock (mitigation: --force flag + per-namespace scoping per Q4=A; drifted peer in ns-A doesn't block ns-B)
• P10 sizing (mitigation: P10 is the largest phase — drift detection + txn plane; grill may split into P10a/P10b if vertical slice is too large)
• Ingress default migration (mitigation: orca upgrade [REQ-115] handles Traefik binding cutover from :443 to 127.0.0.1:8443 for existing v0.9/v0.10 clusters)
• orca system user on peers (mitigation: net-new operational requirement; peer-setup emits useradd -r orca idempotently; documented in P10)

Deferred to v1.x (out of scope for v0.11)

• sqlite-wal-shared state backend (R-009 abstractions ship in v1.0; backend in v1.x)
• git state backend
• file+flock state backend
• orca cluster setup-shared UX
• HA step-ca (active/passive via systemd)
• Journald log shipping (optional centralized audit)
• Network policy (nftables snippets)
• GPU / TPU constraints

Deferred to v2.x (out of scope for v1.x)

• Full Nomad-HCL parser with no conversion round-trip
• Nomad-API subset for migrating existing Nomad fleets
• Nomad driver bridge
• Helm-equivalent templating (probably never)
• Service mesh beyond Traefik
• CRDs / Operators / Plugin model
• Leader-elected Raft coordinator
• External CA / Let's Encrypt / cert transparency
• Online-only features (HSTS, OCSP stapling, telemetry)
