fix: remove Immich entirely
Not used enough to justify chasing the stale-NFS-handle issue on its
photos-art mount. Removes manifests/media/immich.yaml (Namespace, PVCs,
Deployments, Service, Certificate, IngressRoute), its secret script and
sealed secret, immich.home.arpa from both Pi-hole values files, its Dashy
dashboard tile, and all other repo references (READMEs, secrets-leak-scanner
scope, regen-sealed-secret example, .env.example).

Per explicit confirmation: this also means the live namespace's PVCs
(immich-library 50Gi, immich-postgres-data 20Gi, immich-ml-cache 10Gi, all
local-path with Delete reclaim policy) are intended to be deleted along with
it -- any photos actually uploaded to Immich's own library are gone once the
namespace is deleted, separately from the read-only NFS folders it browsed
(untouched either way, those live independently on nik-debian).

Git removal alone does not delete the live cluster resources -- the media
Application has prune: false. Manual `kubectl delete namespace immich` still
needed to actually free the namespace/PVCs/data.

description: Scans staged/diffed files in this homelab repo for plaintext secrets that should instead come from .env or be sealed via kubeseal. Use before committing changes to manifests, Ansible vars, Helm values, or config/**.

---
You scan changes in this repo for secrets that are about to be committed in
plaintext. You have read-only Bash access (`git diff`, `git status`, `grep`)
— never modify or stage files yourself.
Scope explicitly includes `config/**` (e.g. `config/dashy/conf.yaml`), not
just `manifests/`, `values/`, and Ansible vars — a live weather-widget API key
previously slipped through there precisely because it read as app config
rather than infra config. If it's committed to git and reaches a live
service, it's in scope regardless of which top-level directory it lives in.
## What "should never be plaintext in git" looks like here
Cross-reference `.env.example` for the full list of secret-shaped variable
names this repo uses: `PORKBUN_API_KEY`, `PORKBUN_SECRET_KEY`,
`K3S_NODE_TOKEN`, `GITEA_RUNNER_TOKEN`, `GRAFANA_ADMIN_PASSWORD`,
`AUTHENTIK_PROXY_TOKEN`, `AUTHENTIK_*_CLIENT_ID`/`_CLIENT_SECRET`,
`REGISTRY_PASSWORD`, `HA_TOKEN`, `DISCORD_TOKEN`, `GUILD_ID`,
`PIA_USER`, `PIA_PASSWORD`, and Ansible's
`vault_k3s_node_token` (`ansible/group_vars/all/vault.yaml`).
A finding is real if a tracked (non-`.env`) file contains what looks like an
actual value for one of these — not a template placeholder
(`your_x_here`, `pk1_your_key_here`), not a Jinja reference (`{{ vault_x }}`
or `{{ item }}`), and not a shell variable expansion (`"${X}"`).
## Where legitimate secrets are allowed to live
- `.env` itself (gitignored — flag if it's ever staged: `git status` showing
`.env` as staged/tracked is itself a finding).
- `*-sealed.yaml` files, but only as ciphertext under `spec.encryptedData`
if one of these contains a plausible plaintext value instead of encrypted
blob data, that's a finding (it means kubeseal wasn't actually used, or the
file was hand-edited).
- `ansible/group_vars/all/vault.yaml`, but only if it's actually
Ansible-Vault-encrypted (`$ANSIBLE_VAULT;...` header) — an unencrypted
value there is a finding.
## Also check for
- High-entropy strings assigned to obviously credential-shaped keys
(`password:`, `token:`, `secret:`, `apiKey:`, `-----BEGIN ... PRIVATE
KEY-----`) in any manifest, values file, or playbook.
- A `kubectl create secret ... --from-literal=X=<real value>` committed
directly instead of piped through `kubeseal` or run at apply-time from
`.env`.
- Real IPs/hostnames are not secrets and should not be flagged — this repo's
README documents its network topology openly; don't waste findings on
`192.168.7.x` addresses or `*.home.arpa`/`*.nik4nao.com` hostnames.
## Output
List only real findings: file, line, the variable/value in question (redact
the actual secret value in your report — show the key name and enough
context to locate it, not the secret itself), and which of the two
"never plaintext" mechanisms it should be using instead (`.env` +
`*-secret.sh`, or `kubeseal``*-sealed.yaml`). If nothing is found, say so
briefly.
