ingress_factory: replace protected bool with auth enum + audit pass across 100 stacks
...
Phase 3+4 of default-deny ingress plan. Replaces the `protected = bool` (default
false → unprotected) variable in `modules/kubernetes/ingress_factory` with
`auth = string` enum (default "required" → fail-closed). Touches every
ingress_factory caller so the audit decision is recorded explicitly in code.
ingress_factory (Phase 3):
- `auth = "required"`: standard Authentik forward-auth (the legacy
`protected = true` semantic).
- `auth = "public"`: forward-auth via the new `authentik-forward-auth-public`
middleware → dedicated public outpost → guest auto-bind. Logged-in users
keep their real identity.
- `auth = "none"`: no Authentik middleware. For Anubis-fronted content, native
client APIs (Git, /v2/, WebDAV), webhook receivers, the Authentik outpost
itself.
- `effective_anti_ai` default flips ON only when `auth = "none"` (auth-gated
ingresses don't need anti-AI noise; the auth flow already discourages bots).
Audit pass (Phase 4) across 96 ingress_factory call sites:
- 49 explicit `protected = true` → `auth = "required"`
- 8 explicit `protected = false` → `auth = "none"` (5) or `auth = "public"` (3)
- 64 previously-default (no protected line) → `auth = "required"` ADDED, then
reviewed individually:
* 9 Anubis-fronted (blog, www, kms, travel, f1, cyberchef, jsoncrack,
homepage, wrongmove UI, privatebin) → `auth = "none"`
* 22 native-client / programmatic surfaces (Forgejo Git+/v2/, webhook
handler, claude-memory MCP, Nextcloud WebDAV, Matrix, Vault CLI/OIDC,
xray VPN, ntfy, woodpecker webhooks, n8n triggers, ntfy push, dawarich
location ingestion, immich frame kiosk, headscale CP, send anonymous
drops, rybbit beacon, vaultwarden API, Authentik UI itself + outposts) →
`auth = "none"`
* Remaining ~33 → `auth = "required"` confirmed (admin tools, internal
UIs, services without app-level auth)
- Smoke-test promotions to `auth = "public"`: fire-planner public UI,
k8s-portal API, insta2spotify callback.
Three call sites in wrapper modules (`stacks/freedify/factory/`,
`stacks/reverse-proxy/modules/reverse_proxy/`) keep their internal `protected`
bool — they translate to `auth` internally, out of scope for this rename.
Behavior change: previously-default ingresses now fail closed (require
Authentik login) unless explicitly flipped to `auth = "none"` or
`auth = "public"`. This is the audit goal — no more accidentally-unprotected
surfaces. Sites that were intentionally public (Anubis content, native APIs,
webhooks) are now explicitly recorded as `auth = "none"`.
Drive-by: `modules/create-vm/main.tf` picked up cosmetic alignment via
`terraform fmt -recursive` during the audit. Behavior-neutral.

Reduce disk write amplification across cluster (~200-350 GB/day savings) [ci skip]
...
- Prometheus: persist metric whitelist (keep rules) to Helm template, preventing
regression from 33K to 250K samples/scrape on next apply. Reduce retention 52w→26w.
- MySQL InnoDB: aggressive write reduction — flush_log_at_trx_commit=0, sync_binlog=0,
doublewrite=OFF, io_capacity=100/200, redo_log=1GB, flush_neighbors=1, reduced page cleaners.
- etcd: increase snapshot-count 10000→50000 to reduce WAL snapshot frequency.
- VM disks: enable TRIM/discard passthrough to LVM thin pool via create-vm module.
- Cloud-init: enable fstrim.timer, journald limits (500M/7d/compress).
- Kubelet: containerLogMaxSize=10Mi, containerLogMaxFiles=3.
- Technitium: DNS query log retention 0→30 days (was unlimited writes to MySQL).
