vault: canonical Production Vault Access Process + sync vault + migrate koby/koonimo

- Vault SYNCED: mumuni/koby/koonimo rotated keys written to Infisical (all validate 200).
  Vault is source of truth again (was stale since session-13 rotations).
- Koby (.129) + Koonimo (.114) migrated from hardcoded systemd drop-ins to
  infisical-gateway.sh wrapper (live vault injection, .env fallback safety net).
  4/5 agents now vault-backed (abiba/mumuni/koby/koonimo).
- New § Production Vault Access Process: canonical 7-step pattern, migration status
  table, key rotation procedure, why-it's-non-fail rationale.
- Fixed stale notes: 'vault sync PENDING' (now synced), 'Abiba key IS master key'
  (now a proper agent key sk-sxbphLvk1OU).
- Tanko (user jerome, not systemd) documented as pending migration.
- hermes-key-enforcement: cross-ref to canonical process, drop-ins deprecated.

+## Production Vault Access Process (canonical, 2026-07-16)
+
+The non-fail approach to agentic vault access. Deployed on 4/5 agents (tanko pending —
+runs as user `jerome`, not systemd root, needs user-scope adaptation).
+
+### The canonical pattern
+
+1. **infisical CLI** installed on the host (`/usr/local/bin/infisical` or `/usr/bin/infisical`).
+2. **Service token** (Infisical Machine Identity, `st.…`) stored root-only at `/root/.infisical-token` (`chmod 600`).
+   - Interim: the shared `abiba` service token (`st.8e848433…`) has READ+WRITE on the `agents` project.
+   - Proper: one machine identity per agent (create in Infisical UI → Project Settings → Machine Identities).
+3. **`infisical-gateway.sh` wrapper** at `/root/.hermes/infisical-gateway.sh` (`chmod 700`):
+   ```bash
+   #!/bin/bash
+   export INFISICAL_API_URL="https://vault.sysloggh.net"
+   TOKEN=$(cat /root/.infisical-token)
+   LOG=/root/.hermes/logs/gateway.log; mkdir -p /root/.hermes/logs
+   while true; do
+     infisical run --token="$TOKEN" --projectId=322fceab-39da-4854-a55a-568e76c0f13f \
+       --env=prod --domain=https://vault.sysloggh.net -- bash -c '
+         . /root/.hermes/.env 2>/dev/null   # [FALLBACK Rule 3] safety net only
+         export LITELLM_API_KEY="$<AGENT>_LITELLM_API_KEY"
+         exec <HERMES_VENV>/bin/python -m hermes_cli.main gateway run
+       ' >> $LOG 2>&1
+     sleep 5   # restart on exit
+   done
+   ```
+4. **Agent key in vault** as `<AGENT>_LITELLM_API_KEY` (e.g. `KOBY_LITELLM_API_KEY`). Vault = source of truth.
+5. **`.env` fallback** at `/root/.hermes/.env` (`chmod 600`) with the same key — safety net ONLY for vault outage (Rule 3/13). Must be kept in sync on rotation.
+6. **systemd service** `hermes-gateway.service` with `ExecStart=/root/.hermes/infisical-gateway.sh`. NO `litellm-key.conf` drop-in (those hardcode keys and rot).
+7. **NEVER hardcode** LiteLLM keys in systemd drop-ins, config.yaml, or /etc/environment. The wrapper injects live from vault.
+
+### Why this is non-fail
+
+- **No rot**: keys pulled live from vault at every gateway start. Rotation = one `infisical secrets set` + `systemctl restart`. No per-host file edits.
+- **Survives vault outage**: the `.env` fallback (Rule 3) keeps the gateway running if Infisical is unreachable.
+- **Survives gateway crash**: the wrapper's `while true` + systemd `Restart=on-failure` revive the gateway.
+- **Auditable**: `cat /proc/$(pgrep hermes_cli)/environ` shows the live key; `infisical secrets` shows the vault source.
+
+### Migration status (2026-07-16)
+
+| Agent | Host | Pattern | Vault key | Status |
+|-------|------|---------|-----------|--------|
+| abiba | .24 | `infisical run` (pi agent wrapper, service token) | ABIBA_LITELLM_API_KEY | ✅ vault-backed |
+| mumuni | .123 | infisical-gateway.sh + user-login machine identity | MUMUNI_LITELLM_API_KEY | ✅ vault-backed |
+| koby | .129 | infisical-gateway.sh + service token (migrated 2026-07-16) | KOBY_LITELLM_API_KEY | ✅ vault-backed |
+| koonimo | .114 | infisical-gateway.sh + service token (migrated 2026-07-16) | KOONIMO_LITELLM_API_KEY | ✅ vault-backed |
+| tanko | .122 | **hardcoded in config.yaml** (runs as user jerome, not systemd) | TANKO_LITELLM_API_KEY | ⚠️ TODO: migrate to user-scope wrapper |
+
+### Tanko migration (pending)
+
+Tanko runs the gateway as user `jerome` (not root/systemd), with the key hardcoded in
+`/home/jerome/.hermes/config.yaml` (`api_key: sk-CggiHWlamQy…`, valid but not vault-sourced).
+Migration: create a user-scope systemd service (`~/.config/systemd/user/hermes-gateway.service`)
+with `infisical-gateway.sh` wrapper in jerome's home, token at `~/.infisical-token`, lingering
+enabled (`loginctl enable-linger jerome`) so the user service runs without a login session.
+
+### Key rotation procedure (one vault operation with this standard)
+
+1. Generate new key: `POST /key/generate` (master key, admin).
+2. Update vault: `infisical secrets set <AGENT>_LITELLM_API_KEY=sk-NEW --token=$TOKEN --projectId=322fceab… --env=prod --domain=https://vault.sysloggh.net`.
+3. Update `.env` fallback: `echo '<AGENT>_LITELLM_API_KEY=sk-NEW' > /root/.hermes/.env && chmod 600 /root/.hermes/.env`.
+4. Restart: `systemctl restart hermes-gateway`. The wrapper pulls the new key live.
+5. Verify: `curl -H "Authorization: Bearer sk-NEW" http://192.168.68.116/v1/models` → 200.
