+# Bash Capability Map — v0.9 (grill C-18)
+
+Maps every capability in the shipped `internal/transport` package to its
+bash-side equivalent (or accepted drop with recorded rationale) in the v0.9
+re-architecture. The grill (C-18) required this mapping so capability
+regressions are visible, not silent.
+
+| Shipped capability (internal/transport) | Bash-side equivalent | Status | Rationale |
+|---|---|---|---|
+| Retry with exponential backoff (`retry.go`: 100ms start, ×2, cap 5s, max 5 attempts) | `orca-retry()` function in `scripts/lib/orca-retry.sh` (to be written in v0.9-P01 SSH-push transport phase, REQ-073) | **planned** (v0.9-P01) | SSH dial/exec failures need the same bounded retry. The pattern is transport-agnostic; the Go retry logic is extracted into the new `internal/sshpush/` package and a bash-side helper mirrors it for the lead-applier scripts. |
+| Idempotency keys (`idempotency.go`: in-memory `sync.Map` of keys, `X-Orca-Idempotency-Key` header) | Content-addressed filenames — skip SCP if the target hash already exists on the peer | **planned** (v0.9-P01) | SSH-push doesn't have HTTP headers; idempotency is achieved by content-addressing the rendered file (`<hash>.unit`) and skipping if the peer already has it. The bash applier checks `test -f /run/orca/<hash>` before applying. |
+| Structured mTLS failure logging (`handshake_log.go`: slog JSON per mTLS failure) | `orca_log_error` via `scripts/lib/orca-log.sh` (C-17, shipped in this phase P00) | **dropped (mTLS removed by R-001)** | The v0.9 re-architecture removes mTLS daemon-to-daemon transport entirely (R-001). SSH failures are logged via the new `orca_log_*` functions which emit the same slog-compatible JSON field set (ts, level, actor, action, resource, result, error) to syslog. The mTLS-specific handshake-log fields (cipher suite, TLS version, cert SAN) have no SSH equivalent and are dropped — the SSH error message is captured in the `error` field instead. |
+| TLS 1.3 + AEAD cipher allowlist (`mtls.go`: MinVersion=tls.VersionTLS13, CipherSuites limited) | SSH's own cipher config (`/etc/ssh/sshd_config` `Ciphers`, `MACs`, `KexAlgorithms`) managed by the operator | **dropped (transport replaced)** | R-001 replaces mTLS HTTP with SSH. SSH's transport security is governed by the peer's sshd_config, not the orca binary. The CLI's SSH client (`golang.org/x/crypto/ssh`, already a dep) uses Go's default modern SSH cipher set. The PRD does not require orca to manage sshd_config cipher policy in v0.9. |
+| mTLS client/server handshake (`mtls.go`: `MTLSClient`, daemon-side `SubmitHandler`) | `ssh.Dial` + `ssh.PublicKeys` auth (CLI-side `internal/sshpush/`, REQ-073) | **replaced** (v0.9-P01) | The daemon-to-daemon mTLS handshake is replaced by CLI-to-server SSH. The CLI holds an Ed25519 key (`cluster/orca_ssh_key`, D-037) and authenticates to each peer's sshd. TOFU host-key handling (`proxmox.TOFUHostKeyCallback`, v0.8 REQ-058) is reused for all peers, not just Proxmox. |
+
+## Net-new capabilities in v0.9 (no shipped equivalent)
+
+| Net-new capability | Bash-side | Status |
+|---|---|---|
+| Transaction bundle apply (R-010, REQ-075) | `orca-apply-render.sh` (v0.10-P10) | planned |
+| Drift detection (R-010) | `orca-drift.sh` (v0.10-P10) | planned |
+| Per-node state collection | `orca-collect.sh` (v0.10-P09) | planned |
+| Lead aggregation | `orca-aggregate.sh` (v0.10-P09) | planned |
+| Credential cleanup (5-min shred) | `orca-cleanup-credentials.sh` (v0.10) | planned |
+| Render-bundle validation (C-16) | `orca-verify-render.sh` (shipped this phase P00) | ✅ shipped |
+| Structured logging (C-17) | `orca-log.sh` (shipped this phase P00) | ✅ shipped |
+
+## Review cadence
+
+This map is reviewed at each phase that introduces or modifies a bash
+script. The security-engineer persona reviews the SSH trust surface; the
+devops-engineer persona reviews the bash tooling gate (C-15..C-18).

 ### I-M-001 — `orca daemon` deprecation command and build-tag removal path
 - **Tier**: mechanical

Big-bang removal would break the v0.8→v1.0 migration path (v1.0-P14) because `orca upgrade --to-v1.0` must run against a live v0.8 cluster that still has daemons. Proposal: (1) in v0.9, `orca daemon` emits a deprecation warning and still runs (dual-write window); (2) in v1.0, `orca daemon` is repurposed to `orca daemon drain-and-stop` (stops v0.8 daemons on peers via SSH, confirms workloads survive via systemd); (3) post-v1.0, the command and `internal/daemon/` are deleted. Add `// Deprecated` Go doc comments + `slog.Warn` on every run.

 - **Description**: R-001 says "no orca binary on servers." R-010 says the lead applies desired-state transactionally. Unresolved: does the lead run `orca-pull.sh` (pure bash that SCPs a desired-state bundle and applies it via `systemctl daemon-reload` + `systemctl restart`) or does the operator's CLI SSH into the lead and runs `orca apply` remotely (which would put an orca binary on the lead, violating R-001)? The PRD's intent is the former: the lead is bare Linux with systemd timers + bash. Proposal: (1) the CLI renders a *transaction bundle* (tarball of desired-state files + `apply.sh` + `verify.sh`) on the operator host; (2) SCPs it to the lead's `/run/orca/txns/<txn-id>/`; (3) the lead's systemd timer runs `/run/orca/txns/<txn-id>/apply.sh` which idempotently applies and runs verify; (4) the CLI polls the lead for txn status via SSH (`cat /run/orca/txns/<txn-id>/status.json`). The bash scripts are generated by the CLI's emitter (I-B-002), not hand-written per cluster.

(3) **Cert signing API**: workloads request SVIDs via `step ca token` (JWE provisioner token minted by CLI) → `step ca certificate`. The CLI mints the token because it holds the provisioner password (in `cluster/master.key`-derived form).

+- **Description**: R-011 specifies `.env.secrets` with AES-256-GCM, per-line nonce, master key at `cluster/master.key`. §23 puts this in v0.10-P03. Design: (1) `cluster/master.key` is a 32-byte random key generated by `orca init` (extend v0.8 `internal/security/ca.go`'s `WriteAtomic` pattern for the file write). (2) Each line of `.env.secrets` is `base64(nonce || ciphertext || tag)` where `nonce = random(12 bytes)` and `ciphertext = AES-256-GCM(plaintext, key=master.key, nonce, aad=line-number)`. (3) The AAD is the 1-indexed line number to prevent line-swap attacks. (4) Decryption reads the master key, iterates lines, decrypts with AAD.

 - **Rationale**: R-011 is precise about the crypto but §23 doesn't specify key derivation, AAD, or CLI surface. The existing `redact.go` and `WriteAtomic` are reusable.

Rules are registered in a `ruleRegistry` and individually testable. The linter is pure (no I/O) — it checks the spec against static rules, not live cluster state (that's `orca job verify`, P12).

 ### I-C-001 — v0.8→v1.0 migration ordering: daemon deprecation vs. new model rollout
 - **Tier**: cross-cutting
-- **Description**: The PRD §24 covers *data* migration but not *binary/daemon* deprecation ordering. The risk: v0.9 builds the new Markdown+kinds+runtime+SSH-push model, but v0.8 daemons are still running on peers. If v0.9 ships the new `orca job run` (Markdown) while the old daemon is still the execution engine, there's a split-brain: new specs can't run on the old daemon. Ordering proposal: (1) v0.9 ships the new parser + kinds + runtime + SSH-push *alongside* the old daemon (dual-write window); (2) `orca job run` in v0.9 uses the new SSH-push path if the spec is `.md` and the old daemon path if `.hcl`; (3) v1.0-P05 (drain) stops the old daemons; (4) v1.0-P14 (migration) converts remaining `.hcl` specs to `.md` and removes the daemon. The dual-write window means v0.9 is *not* a clean break — it's a compatibility milestone. This must be explicit in the plan or the v0.9 phases will assume the daemon is gone.

 - **Rationale**: Single largest risk in the re-architecture. §23 implicitly assumes v0.9 builds the new model in isolation, but existing deployments have running daemons.

 - **Tier**: cross-cutting
-- **Description**: R-001 is an invariant: "no orca Go binary on any server." §23 v1.0-P14 says "post-invariant checks" but doesn't specify them. `orca doctor` must gain a `doctor no-orca-on-server` check that SSHs to each peer and verifies: (1) no `orca` binary in PATH (`ssh peer which orca` returns nothing), (2) no `orca` systemd service (`ssh peer systemctl list-units 'orca*'` returns empty), (3) no `orca` process (`ssh peer pgrep -x orca` returns empty), (4) no `/etc/orca/` directory. This check must run *after* v1.0-P05 (drain) and *before* v1.0-P16 (ship). The v0.8 `internal/proxmox/bootstrap.go` already has the SSH session infrastructure (`sessionRunner` seam) — directly reusable for the doctor check.

 ### I-C-006 — Dual-write window: can v0.9 ship new parser while old daemon runs?
 - **Tier**: cross-cutting
-- **Description**: Focused version of I-C-001. The specific question: in v0.9, when the new Markdown parser + kinds + SSH-push are shipped, can they coexist with v0.8 daemons still running on peers? The answer depends on whether `orca job run <spec.md>` uses the new SSH-push path (bypassing the daemon entirely) or routes through the old daemon. If it bypasses, the daemon is irrelevant for new specs but still serves old `.hcl` specs. If it routes through, the daemon can't handle `.md` specs. Proposal: v0.9 `orca job run` dispatches on extension (`.md`→SSH-push new path, `.hcl`→old daemon path) via the parser dispatcher (I-M-004). This is a *dual-write window* where both paths coexist. The daemon is not removed until v1.0-P05 (drain). The risk: if a `.md` workload and a `.hcl` workload target the same node, the SSH-push path writes systemd units directly while the daemon also manages units — they can conflict. Mitigation: the SSH-push path writes to a separate systemd unit namespace (`orca-v1-<alloc>.service`) while the daemon uses `orca-<job>.service`. No unit name overlap = no conflict.

+# Bash Testing Policy (grill C-15)
+
+Every bash script under `scripts/` MUST have at least one bats test covering
+the happy path and one covering the failure path. This is the compensating
+control for bash being exempt from the Go coverage gate (D-186).
+
+## Framework
+
+- **bats** — `bats scripts/tests/*.bash` runs all bash tests.
+- **shellcheck** — `shellcheck scripts/*.sh scripts/lib/*.sh scripts/tests/*.bash` static analysis.
+- **shfmt** — `shfmt -d scripts/` formatting check (optional; skip if not installed).
+
+## Install (if missing)
+
+```bash
+# bats
+npm install -g bats    # or: git clone https://github.com/bats-core/bats-core.git && ./bats-core/install.sh /usr/local
+# shellcheck
+apt-get install -y shellcheck
+# shfmt (optional)
+mvdan.cc/sh (go install mvdan.cc/sh/v3/cmd/shfmt@latest)
+```
+
+## Running
+
+```bash
+make test-bash   # runs bats (skips gracefully if bats missing)
+make lint-bash   # runs shellcheck + shfmt (skips gracefully if missing)
+make test        # runs both Go + bash tests
+make lint        # runs both Go + bash lint
+```
+
+## Test file convention
+
+- Test files live in `scripts/tests/<script-name>_test.bash`.
+- Source `load test_helper` at the top of every test file.
+- Happy path: `@test "<script> happy path" { ... }`
+- Failure path: `@test "<script> failure path" { ... }`
+- Use `run <command>` + `assert_status`/`assert_contains`/`assert_not_contains` from test_helper.
