chore(P13): final review + audit — v0.13 milestone complete

All 15 v0.13 requirements (REQ-149..REQ-163) marked complete. All 14 phases shipped (P0..P13, tags v0.12.0..v0.12.12). 163 requirements consistent with roadmap (verify-reqs passes). ROADMAP.md marks v0.13 COMPLETE. All Go tests pass. Build clean. Milestone deliverables: - R-022: orca job run deploys to remote nodes via scheduler+emitter+SSH-push - R-023: zero-trust enforcement wired (acl.Check on every request path) - 11 injection vectors fixed - Go toolchain bumped to 1.25.12 (24 stdlib vulns closed) - Audit chain race fixed (BEGIN IMMEDIATE) - Concurrency safety (SQLite busy_timeout, flock, cache invalidation) - Transport safety (typed errors, IPv6, SSH timeouts, signal handler) - Migration safety (job stop real systemctl, backup+atomic-rename) - Observability (7 new metrics, security headers) - Doc drift fixed (README, cli.md, CHANGELOG, verify-reqs regex) - --type linux SSH-join for Ubuntu workers - docs/uat.md (3-host topology, 35-claim matrix) - scripts/uat-signoff.sh (35 assertions, idempotent, v1.0 gate) - scripts/uat-smoke.sh (13 CI assertions) v1.0.0 production-ready tag stays deferred for UAT signoff. Operator runs scripts/uat-signoff.sh, pastes output, CI agent cuts v1.0.0. ---ci--- project: orca phase: 13 milestone: v0.13 status: complete requirements: covered: [149,150,151,152,153,154,155,156,157,158,159,160,161,162,163] ---/ci---

+## v0.13 milestone (in progress) — tag line v0.12.x
+
+The v0.13 milestone is **Production Hardening Round 2 + UAT Plan**.
+Three deep codebase sweeps (security, reliability, feature/doc claims)
+surfaced ~60 gaps beyond v0.12. v0.13 closes all critical/high/medium
+findings and delivers the UAT plan + signoff script that gates the
+v1.0.0 cut.
+
+**Load-bearing architectural changes**:
+- **R-022** — `orca job run` deploys to remote nodes via the scheduler →
+  emitter → SSH-push pipeline. The local `exec.CommandContext` path is
+  removed (P03).
+- **R-023** — Zero-trust enforcement is operationally wired: `acl.Check`
+  is invoked on every daemon handler + sshpush + txn apply path;
+  `acl.json` is 0600; audit `actor` carries OIDC sub/SVID; WebAuthn
+  registration requires auth; `cluster seal`/`unseal` + `doctor audit`/
+  `doctor modes` CLI commands exist (P04, P05).
+

+
+## v0.12 milestone — COMPLETE (tag line v0.11.x)
+
+The v0.12 milestone is **Security Hardening (Zero-Trust Identity)**.
+Comprehensive security hardening across the entire attack surface
+including the OS, plus adoption of a zero-trust identity model. 25
+threat-model findings (F1..F25) closed. R-021 adopted: no Orca-issued
+credentials — human identity is exclusively external (OIDC), machine
+identity is exclusively mTLS/SPIFFE.
+
+**Milestone release**: `v0.11.28` (29 phases, tags `v0.11.0`..`v0.11.28`).

-# Security Runbook (v0.12)
+# Security Runbook (v0.13)

-## Master Key Seal/Unseal
+This runbook documents the operational security procedures for orca's
+zero-trust identity model (R-021): human identity is exclusively
+external (OIDC), machine identity is exclusively mTLS/SPIFFE, and no
+passwords / Orca-issued tokens / CA-key passphrases exist anywhere in
+the system. The v0.12 milestone shipped these capabilities; the v0.13
+milestone wired them operationally (R-023).

- `orca cluster seal`: encrypts master key with OIDC-derived key;
-  prints 5 Shamir shards for offline recovery.
- `orca cluster unseal`: operator authenticates via OIDC; master key
-  unwrapped into memory; zeroed on shutdown.
- `orca cluster unseal --recovery`: if IdP lost, present 3 of 5 shards.
+## Master Key Seal/Unseal (REQ-147, P05)

-## Master Key Rotation
+The cluster master key (`ClusterDir()/master.key`, mode 0600) encrypts
+all namespace `.env.secrets` via per-namespace HKDF-SHA256 sub-keys
+(AES-256-GCM). The master key can be **sealed** (encrypted at rest) and
+**unsealed** (unwrapped into memory for use).

-`orca secrets rotate-master [--dry-run]`: generates new master key,
-re-encrypts all namespace secrets, re-seals. Atomic + automatic rollback.
+### Seal
+
+```bash
+orca cluster seal
+```
+
+Encrypts the raw master key with a key derived from either:
+- the OIDC ID token subject (if `orca auth login` has been run), or
+- the cluster CA fingerprint (mTLS-only offline path, D-241).
+
+The sealed blob is written to `ClusterDir()/master.key.sealed` (0600).
+**Five Shamir shards (3-of-5 recovery)** are printed to stdout — store
+them offline. The raw master key is then deleted from disk so the
+cluster is sealed at rest.
+
+### Unseal
+
+```bash
+orca cluster unseal
+```
+
+Reads the sealed blob and unwraps the master key using the OIDC ID
+token subject or the cluster CA fingerprint. The unwrapped key is
+written back to `ClusterDir()/master.key` (0600) and zeroed from
+memory on process exit.
+
+### Recovery (IdP lost)
+
+```bash
+orca cluster unseal --recovery
+```
+
+If the IdP is permanently lost, the operator is prompted for 3 of the
+5 Shamir shards printed at seal time. With quorum, the master key is
+reconstructed and written back to disk. If quorum is unavailable, the
+cluster is unrecoverable by design (C-35: no backdoor).
+
+## Master Key Rotation (REQ-129, C-30)
+
+```bash
+orca secrets rotate-master [--dry-run]
+```
+
+Generates a new master key, re-encrypts every namespace's
+`.env.secrets` under the new key, and re-seals the master key to OIDC.
+With `--dry-run`, reports affected namespaces without writing.
+
+- **Atomic per-namespace**: each namespace is re-encrypted independently.
+- **Automatic rollback**: on any namespace failure, the old sealed key
+  is restored (C-30).
+- **No passphrase** (R-021): the master key is sealed to OIDC, not to a
+  human-typed passphrase.
+
+## File-Mode Audit (REQ-033, REQ-130, F13)
+
+```bash
+orca doctor modes
+```
+
+Verifies file modes on security-sensitive files across `ORCA_HOME`:
+- private keys / secrets: `0600`
+- certs / public keys: `0644`
+
+Exits 0 if all files have correct modes; exits 1 if any violation is
+found. Missing files are not counted as violations.
+
+Checks: SSH key, master key (sealed blob), server cert/key,
+known_hosts, `acl.json`, OIDC client secret.
+
+## Audit Log Tamper-Evidence (REQ-125, F2)
+
+```bash
+orca doctor audit
+```
+
+Verifies the audit log hash chain. Opens the orca SQLite DB, recomputes
+the hash chain from the first audit entry, and reports the chain head
+hash. If any entry's `entry_hash` or `prev_hash` link does not match the
+recomputed value, the chain has been tampered with and the command
+exits non-zero.
+
+The audit log is append-only (SQLite trigger blocks
+UPDATE/DELETE). Each entry's `actor` field carries the OIDC `sub` or
+SPIFFE SVID. Run this after any suspected intrusion or as part of a
+regular audit cadence.
+
+## Sudoers Audit (REQ-134, F22)
+
+```bash
+orca doctor proxmox
+```
+
+Audits the `/etc/sudoers.d/orca` file against the expected allowlist:
+- `pct` + `qm` with NOEXEC
+- `apt-get` / `dpkg` excluded (or NOEXEC'd)
+- `pvesh` EXCLUDED (AD-020: pvesh can bypass NOEXEC via the API execute
+  endpoint)
+
+## nft Audit (REQ-133, F21)
+
+```bash
+orca doctor nft
+```
+
+Audits the live nftables ingress ruleset against the on-disk
+`/etc/nftables.d/orca.nft` hash (recorded at the latest applied txn).
+Reports drift if the live ruleset does not match. Also verifies:
+- table exists
+- DNAT `:443 → 127.0.0.1:8443` and `:80 → 127.0.0.1:8080` present
+- rate-limit meter present

+# Orca User Acceptance Testing (UAT) Plan
+
+**Version**: v0.13 (production hardening round 2)
+**Gate**: v1.0.0 production-ready tag is deferred until this UAT passes
+**Signoff**: run `scripts/uat-signoff.sh` on the lead node and paste the output back
+
+## Prerequisites
+
+### Hardware
+
+| Role | OS | Requirements |
+|------|-----|-------------|
+| **lead** | Ubuntu 22.04 LTS | Operator laptop or VM; SSH key; `orca` binary (built from v0.13 tag) |
+| **pve01** | Proxmox VE 8/9 | Bare-metal or nested; SSH root access; orca SSH key pre-staged |
+| **worker01** | Ubuntu 22.04 LTS | VM or bare-metal; SSH root access; orca SSH key pre-staged |
+
+### Alternative topology (3x Ubuntu, no Proxmox)
+
+If a Proxmox host is unavailable, run the UAT with 3x Ubuntu hosts.
+Use `--type linux` for all remote nodes. Proxmox-specific claims
+(`doctor proxmox`, PVE role, sudoers) are **skipped** in this path.
+The signoff script reports exercised vs. skipped claims.
+
+### Pre-staging
+
+1. Build orca from the v0.13 tag:
+   ```sh
+   git clone https://git.cloudinit.dev/coreci/orca.git
+   cd orca && git checkout v0.12.13
+   make build
+   # binary is at bin/orca
+   ```
+
+2. Generate the orca SSH keypair on the lead:
+   ```sh
+   ssh-keygen -t ed25519 -f ~/.ssh/orca_ed25519 -N ""
+   ```
+
+3. Pre-stage the orca public key on pve01 and worker01:
+   ```sh
+   ssh-copy-id -i ~/.ssh/orca_ed25519.pub root@pve01
+   ssh-copy-id -i ~/.ssh/orca_ed25519.pub root@worker01
+   ```
+
+4. Pin host-key fingerprints (optional but recommended):
+   ```sh
+   ssh-keyscan pve01 | ssh-keygen -lf -
+   ssh-keyscan worker01 | ssh-keygen -lf -
+   ```
+
+## Step-by-step UAT
+
+### Step 1: Initialize the cluster
+
+```sh
+export ORCA_HOME=~/orca-uat
+orca init
+```
+
+**Expected**: cluster directory created, CA cert generated, localhost node registered.
+
+### Step 2: Onboard the Proxmox host
+
+```sh
+orca node join --type proxmox \
+  --host pve01 \
+  --ssh-user root \
+  --ssh-key ~/.ssh/orca_ed25519 \
+  --host-key-fingerprint SHA256:<fingerprint>
+```
+
+**Expected**: SSH bootstrap succeeds, orca user created, PVE role assigned, node registered as `ready` with `kind=proxmox`.
+
+### Step 3: Onboard the Ubuntu worker
+
+```sh
+orca node join --type linux \
+  --host worker01 \
+  --ssh-user root \
+  --ssh-key ~/.ssh/orca_ed25519 \
+  --host-key-fingerprint SHA256:<fingerprint>
+```
+
+**Expected**: SSH bootstrap succeeds, orca user created, drift-events dir created, node registered as `ready` with `kind=linux`.
+
+### Step 4: Verify nodes
+
+```sh
+orca node list
+orca node list --json
+```
+
+**Expected**: 3 nodes listed (localhost + pve01 + worker01), all `ready`.
+
+### Step 5: Set capacity on remote nodes
+
+```sh
+orca node capacity set --node pve01 --cpu 4 --memory 8192 --disk 100000
+orca node capacity set --node worker01 --cpu 2 --memory 4096 --disk 50000
+orca node capacity list
+```
+
+**Expected**: capacity shown for both remote nodes.
+
+### Step 6: Create a namespace
+
+```sh
+orca ns create prod
+orca ns list
+```
+
+**Expected**: `prod` namespace listed.
+
+### Step 7: Deploy the full stack
+
+Deploy each service from `examples/full-stack/`:
+
+```sh
+orca job run examples/full-stack/web-app.md --target pve01
+orca job run examples/full-stack/api.md --target pve01
+orca job run examples/full-stack/worker.md --target worker01
+orca job run examples/full-stack/postgres.md --target pve01
+orca job run examples/full-stack/log-shipper.md --target worker01
+```
+
+**Expected**: each job is scheduled on the target, systemd unit deployed via SSH-push, job status `running` or `complete`.
+
+### Step 8: Verify deployment
+
+```sh
+orca job list
+orca job list --json
+```
+
+**Expected**: all 5 jobs listed, with correct target nodes.
+
+On each remote node:
+```sh
+ssh root@pve01 systemctl status 'orca-alloc-*'
+ssh root@worker01 systemctl status 'orca-alloc-*'
+```
+
+### Step 9: Verify Traefik routes
+
+```sh
+ssh root@pve01 ls /etc/traefik/dynamic/
+ssh root@worker01 ls /etc/traefik/dynamic/
+```
+
+**Expected**: `traefik-dynamic-*.yaml` files present on nodes where jobs were deployed.
+
+### Step 10: Migrate between hosts
+
+Migrate `web-app` from pve01 to worker01:
+
+```sh
+orca job migrate web-app --to worker01
+```
+
+**Expected**: job drained on pve01, rescheduled on worker01, new systemd unit deployed.
+
+Verify:
+```sh
+orca job list
+ssh root@worker01 systemctl status 'orca-alloc-*web-app*'
+ssh root@pve01 systemctl status 'orca-alloc-*web-app*' # should be stopped
+```
+
+### Step 11: Aggregate logs
+
+```sh
+orca logs --all-nodes --job web-app --since 5m
+```
+
+**Expected**: log entries from multiple nodes.
+
+### Step 12: ACL enforcement
+
+```sh
+orca acl grant operator-1 --namespace prod --permissions read,write
+orca acl check operator-1 --namespace prod --permission read
+orca acl check operator-1 --namespace prod --permission admin
+```
+
+**Expected**: read+write allowed, admin denied (not granted).
+
+### Step 13: Seal/unseal
+
+```sh
+orca cluster seal --rp-id orca.local
+orca cluster unseal
+orca secrets set prod TEST_KEY --value "test-value"
+orca secrets get prod TEST_KEY
+```
+
+**Expected**: seal succeeds, unseal succeeds, secrets readable post-unseal.
+
+### Step 14: Audit chain
+
+```sh
+orca doctor audit
+```
+
+**Expected**: chain head reported, no tamper detected.
+
+### Step 15: Doctor modes
+
+```sh
+orca doctor modes
+```
+
+**Expected**: all file modes correct, exit 0.
+
+### Step 16: OIDC health
+
+```sh
+orca doctor oidc
+```
+
+**Expected**: Dex unit active, issuer reachable (or WARN if Dex not installed).
+
+### Step 17: Backup and restore
+
+```sh
+orca backup --out /tmp/uat-backup.tar.gz
+orca restore --in /tmp/uat-backup.tar.gz --dry-run
+```
+
+**Expected**: backup succeeds, restore dry-run succeeds.
+
+### Step 18: Drift detection
+
+```sh
+orca drift show
+```
+
+**Expected**: no error (empty drift is fine).
+
+### Step 19: Transaction idempotency
+
+```sh
+orca txn apply <some-txn-dir>
+orca txn apply <some-txn-dir>  # re-run
+```
+
+**Expected**: second apply is idempotent (exit 5 or "already applied").
+
+### Step 20: Metrics
+
+```sh
+orca metrics --addr :9100 &
+sleep 3
+curl -s http://localhost:9100/metrics | grep orca_
+```
+
+**Expected**: expanded metric set present (`orca_jobs_running`, `orca_audit_chain_head`, etc.).
+
+### Step 21: Compat check
+
+```sh
+orca cluster compat-check
+```
+
+**Expected**: exit 0, all nodes compatible.
+
+### Step 22: Run the signoff script
+
+```sh
+scripts/uat-signoff.sh
+```
+
+**Expected**: `UAT SIGNOFF: N/35 assertions passed`, exit 0 iff N==35.

-# WebAuthn / Passkeys (v0.12)
+# WebAuthn / Passkeys (v0.13)

 ## Overview

-The bundled Dex uses a custom WebAuthn connector for password-free
-authentication. Passkeys are public-key credentials — the private key
-never leaves the authenticator (TPM/security key/phone Secure Enclave).
+The bundled Dex uses a custom WebAuthn connector (`orca-webauthn-connector`,
+REQ-148) for password-free authentication. Passkeys are public-key
+credentials — the private key never leaves the authenticator (TPM /
+security key / phone Secure Enclave). This directly satisfies R-021
+(no Orca-issued credentials): the authenticator proves possession of
+the private key without ever exposing it.
+
+The WebAuthn connector ships as part of the v0.12 milestone (P05) and
+is operationally wired in v0.13 (P04: registration requires auth; P06:
+real Dex deployment).

 ## Registration

-`orca auth register` opens the browser to the Dex WebAuthn endpoint.
-After the ceremony (biometric/security key), Dex maps the credential
-ID to an OIDC `sub`. Credentials stored at
-`ClusterDir()/webauthn-credentials.db` (0600, public keys only).
+```bash
+orca auth register [--no-browser]
+```
+
+Opens the browser to the Dex WebAuthn registration page at
+`https://<cluster>/orca/webauthn/register`. The operator authenticates
+via an existing session or admin bootstrap token, then performs the
+WebAuthn ceremony (biometric or security key). After the ceremony,
+Dex maps the credential ID to an OIDC `sub`.
+
+- **`--no-browser`**: print the registration URL instead of opening a
+  browser (useful for headless operators or remote SSH sessions — copy
+  the URL into a local browser).
+
+Credentials are stored at `ClusterDir()/webauthn-credentials.db`
+(mode 0600, public keys only — private keys never leave the
+authenticator and are never stored by orca).
+
+**Example**:
+```bash
+# Interactive (opens browser)
+orca auth register
+
+# Headless / remote SSH (print URL)
+orca auth register --no-browser
+# → https://orca.local/orca/webauthn/register
+```

 ## RP ID

-The relying-party ID is the cluster's Traefik-served domain
-(`--rp-id` on `orca auth init-idp`). HTTPS secure context is provided
-by Traefik (step-ca cert, R-017).
+The relying-party ID is the cluster's Traefik-served domain, set via
+`--rp-id` on `orca auth init-idp` (C-38). The RP ID **must** match the
+cluster's Traefik domain — WebAuthn enforces that the RP ID is a
+registrable domain suffix of the current origin.
+
+HTTPS secure context is provided by Traefik (step-ca cert, R-017).
+WebAuthn requires a secure context (HTTPS or localhost); the step-ca
+cert behind Traefik satisfies this.

 ## Bootstrap Sequence

 1. `orca init` bootstraps the cluster CA (step-ca, mTLS-only).
-2. `orca auth init-idp` deploys Dex behind Traefik (step-ca cert).
-3. First operator registers a passkey via the mTLS-authenticated session.
-4. Subsequent operators use WebAuthn.
+2. `orca auth init-idp --rp-id <cluster-domain>` deploys Dex behind
+   Traefik (step-ca cert) with the WebAuthn connector configured.
+3. First operator authenticates via an existing session or admin
+   bootstrap token, then registers a passkey:
+
+   ```bash
+   orca auth register
+   ```
+
+4. Subsequent operators use WebAuthn login (`orca auth login` opens
+   the browser to the Dex login page; the WebAuthn ceremony is one of
+   the available upstreams).
+
+## Health Check
+
+```bash
+orca doctor oidc
+```
+
+Verifies the bundled Dex OIDC provider is running and the
+`/.well-known/openid-configuration` endpoint responds. Run after
+`orca auth init-idp` or after a Dex config change.
+
+## Security properties
+
+- **No passwords**: WebAuthn is password-free. No password is ever
+  sent to or stored by orca (R-021).
+- **Phishing-resistant**: the WebAuthn protocol cryptographically binds
+  the ceremony to the RP ID, defeating credential phishing.
+- **Private key never leaves the authenticator**: orca stores only
+  public keys.
+- **Secure context required**: HTTPS via step-ca / Traefik (C-38).

Milestone deliverables: - R-022: orca job run deploys to remote nodes via scheduler+emitter+SSH-push - R-023: zero-trust enforcement wired (acl.Check on every request path) - 11 injection vectors fixed - Go toolchain bumped to 1.25.12 (24 stdlib vulns closed) - Audit chain race fixed (BEGIN IMMEDIATE) - Concurrency safety (SQLite busy_timeout, flock, cache invalidation) - Transport safety (typed errors, IPv6, SSH timeouts, signal handler) - Migration safety (job stop real systemctl, backup+atomic-rename) - Observability (7 new metrics, security headers) - Doc drift fixed (README, cli.md, CHANGELOG, verify-reqs regex) - --type linux SSH-join for Ubuntu workers - docs/uat.md (3-host topology, 35-claim matrix) - scripts/uat-signoff.sh (35 assertions, idempotent, v1.0 gate) - scripts/uat-smoke.sh (13 CI assertions) v1.0.0 production-ready tag stays deferred for UAT signoff. Operator runs scripts/uat-signoff.sh, pastes output, CI agent cuts v1.0.0. ---ci--- project: orca phase: 13 milestone: v0.13 status: complete requirements: covered: [149,150,151,152,153,154,155,156,157,158,159,160,161,162,163] ---/ci---	2026-08-10 14:37:33 +00:00
Jon Chery	52e17aefbf	feat(P12): --type linux SSH-join + UAT plan + signoff script (REQ-161..163) --type linux (REQ-161): - internal/linux/bootstrap.go: SSH bootstrap for generic Linux workers (orcas pubkey, system user, drift-events dir; no PVE role/sudoers) - internal/cli/node.go: joinLinux function + --type linux dispatch - peer-setup kept as documented fallback UAT plan (REQ-162): - docs/uat.md: 3-host topology (lead Ubuntu + pve01 Proxmox + worker01 Ubuntu), 22 step-by-step commands, 35-claim matrix, Proxmox prerequisite + alternative 3xUbuntu path (C-48), signoff procedure UAT signoff script (REQ-163, C-47): - scripts/uat-signoff.sh: 35 idempotent read-only assertions, exit 0 iff all pass. Includes 4 critical-path assertions: job deploys to remote, ACL deny-by-default, seal/unseal round-trip, OIDC health - scripts/uat-smoke.sh: 13 CI-tested pure-CLI assertions for .coreci.yml Tests: node join --type linux test, fingerprint test updated, smoke test all 13 pass. ---ci--- project: orca phase: 12 milestone: v0.13 status: complete requirements: covered: [161, 162, 163] ---/ci---	2026-08-10 14:33:29 +00:00
