## Context
foolery, terminal, and claude-memory each had their own
`stacks/<x>/secrets/` directory with a plaintext EC-256 private key
(privkey.pem, 241 B) and matching TLS certificate (fullchain.pem, 2868 B)
for *.viktorbarzin.me. The 92 other stacks under stacks/ symlink
`secrets/` → `../../secrets`, which resolves to the repo-root
/secrets/ directory covered by the `secrets/** filter=git-crypt`
.gitattributes rule — i.e., every other stack consumes the same
git-crypt-encrypted root wildcard cert.
The 3 outliers shipped their keys in plaintext because `.gitattributes`
secrets/** rule matches only repo-root /secrets/, not
stacks/*/secrets/. Both remotes are public, so the 6 plaintext PEM files
have been exposed for 1–6 weeks (commits 5a988133 2026-03-11,
a6f71fc6 2026-03-18, 9820f2ce 2026-04-10).
Verified:
- Root wildcard cert subject = CN viktorbarzin.me,
SAN *.viktorbarzin.me + viktorbarzin.me — covers the 3 subdomains.
- Root privkey + fullchain are a valid key pair (pubkey SHA256 match).
- All 3 outlier certs have the same subject/SAN as root; different
distinct cert material but equivalent coverage.
## This change
- Delete plaintext PEMs in all 3 outlier stacks (6 files total).
- Replace each stacks/<x>/secrets directory with a symlink to
../../secrets, matching the fleet pattern.
- Add `stacks/**/secrets/** filter=git-crypt diff=git-crypt` to
.gitattributes as a regression guard — any future real file placed
under stacks/<x>/secrets/ gets git-crypt-encrypted automatically.
setup_tls_secret module (modules/kubernetes/setup_tls_secret/main.tf) is
unchanged. It still reads `file("${path.root}/secrets/fullchain.pem")`,
which via the symlink resolves to the root wildcard.
## What is NOT in this change
- Revocation of the 3 leaked per-stack certs. Backed up the leaked PEMs
to /tmp/leaked-certs/ for `certbot revoke --reason keycompromise`
once the user's LE account is authenticated. Revocation must happen
before or alongside the history-rewrite force-push to both remotes.
- Git-history scrub. The leaked PEM blobs are still reachable in every
commit from 2026-03-11 forward. Scheduled for removal via
`git filter-repo --path stacks/<x>/secrets/privkey.pem --invert-paths`
(and fullchain.pem for each stack) in the broader remediation pass.
- cert-manager introduction. The fleet does not use cert-manager today;
this commit matches the existing symlink-to-wildcard pattern rather
than introducing a new component.
## Test plan
### Automated
$ readlink stacks/foolery/secrets
../../secrets
(likewise for terminal, claude-memory)
$ for s in foolery terminal claude-memory; do
openssl x509 -in stacks/$s/secrets/fullchain.pem -noout -subject
done
subject=CN = viktorbarzin.me (x3 — all resolve via symlink to root wildcard)
$ git check-attr filter -- stacks/foolery/secrets/fullchain.pem
stacks/foolery/secrets/fullchain.pem: filter: git-crypt
(now matched by the new rule, though for the symlink target the
repo-root rule already applied)
### Manual Verification
1. `terragrunt plan` in stacks/foolery, stacks/terminal, stacks/claude-memory
shows only the K8s TLS secret being re-created with the root-wildcard
material. No ingress changes.
2. `terragrunt apply` for each stack → `kubectl -n <ns> get secret
<name>-tls -o yaml` → tls.crt decodes to CN viktorbarzin.me with
the root serial (different from the pre-change per-stack serials).
3. `curl -v https://foolery.viktorbarzin.me/` (and likewise terminal,
claude-memory) → cert chain presents the new serial, handshake OK.

Two-tier state architecture:
- Tier 0 (infra, platform, cnpg, vault, dbaas, external-secrets): local
state with SOPS encryption in git — unchanged, required for bootstrap.
- Tier 1 (105 app stacks): PostgreSQL backend on CNPG cluster at
10.0.20.200:5432/terraform_state with native pg_advisory_lock.
Motivation: multi-operator friction (every workstation needed SOPS + age +
git-crypt), bootstrap complexity for new operators, and headless agents/CI
needing the full encryption toolchain just to read state.
Changes:
- terragrunt.hcl: conditional backend (local vs pg) based on tier0 list
- scripts/tg: tier detection, auto-fetch PG creds from Vault for Tier 1,
skip SOPS and Vault KV locking for Tier 1 stacks
- scripts/state-sync: tier-aware encrypt/decrypt (skips Tier 1)
- scripts/migrate-state-to-pg: one-shot migration script (idempotent)
- stacks/vault/main.tf: pg-terraform-state static role + K8s auth role
for claude-agent namespace
- stacks/dbaas: terraform_state DB creation + MetalLB LoadBalancer
service on shared IP 10.0.20.200
- Deleted 107 .tfstate.enc files for migrated Tier 1 stacks
- Cleaned up per-stack tiers.tf (now generated by root terragrunt.hcl)

Terragrunt now generates cloudflare_provider.tf (Vault-sourced API key)
and includes cloudflare in required_providers. These are the generated
files from running `terragrunt init -upgrade` across all stacks.

## Context
Deploying new services required manually adding hostnames to
cloudflare_proxied_names/cloudflare_non_proxied_names in config.tfvars —
a separate file from the service stack. This was frequently forgotten,
leaving services unreachable externally.
## This change:
- Add `dns_type` parameter to `ingress_factory` and `reverse_proxy/factory`
modules. Setting `dns_type = "proxied"` or `"non-proxied"` auto-creates
the Cloudflare DNS record (CNAME to tunnel or A/AAAA to public IP).
- Simplify cloudflared tunnel from 100 per-hostname rules to wildcard
`*.viktorbarzin.me → Traefik`. Traefik still handles host-based routing.
- Add global Cloudflare provider via terragrunt.hcl (separate
cloudflare_provider.tf with Vault-sourced API key).
- Migrate 118 hostnames from centralized config.tfvars to per-service
dns_type. 17 hostnames remain centrally managed (Helm ingresses,
special cases).
- Update docs, AGENTS.md, CLAUDE.md, dns.md runbook.
```
BEFORE AFTER
config.tfvars (manual list) stacks/<svc>/main.tf
| module "ingress" {
v dns_type = "proxied"
stacks/cloudflared/ }
for_each = list |
cloudflare_record auto-creates
tunnel per-hostname cloudflare_record + annotation
```
## What is NOT in this change:
- Uptime Kuma monitor migration (still reads from config.tfvars)
- 17 remaining centrally-managed hostnames (Helm, special cases)
- Removal of allow_overwrite (keep until migration confirmed stable)

Kyverno ClusterPolicy reads dependency.kyverno.io/wait-for annotation
and injects busybox init containers that block until each dependency
is reachable (nc -z). Annotations added to 18 stacks (24 deployments).
Includes graceful-db-maintenance.sh script for planned DB maintenance
(scales dependents to 0, saves replica counts, restores on startup).
The + in +00:00 timezone offsets was being URL-decoded to a space,
causing ValueError on the /api/memories/sync endpoint. Build :17
includes the fix. Using versioned tag instead of :latest to avoid
pull-through cache serving stale images.
- Set memory requests = limits across 56 stacks to prevent overcommit
- Right-sized limits based on actual pod usage (2x actual, rounded up)
- Scaled down trading-bot (replicas=0) to free memory
- Fixed OOMKilled services: forgejo, dawarich, health, meshcentral,
paperless-ngx, vault auto-unseal, rybbit, whisper, openclaw, clickhouse
- Added startup+liveness probes to calibre-web
- Bumped inotify limits on nodes 2,3 (max_user_instances 128->8192)
Post node2 OOM incident (2026-03-14). Previous kubelet config had no
kubeReserved/systemReserved set, allowing pods to starve the kernel.
- Add vault provider to root terragrunt.hcl (generated providers.tf)
- Delete stacks/vault/vault_provider.tf (now in generated providers.tf)
- Add 124 variable declarations + 43 vault_kv_secret_v2 resources to
vault/main.tf to populate Vault KV at secret/<stack-name>
- Migrate 43 consuming stacks to read secrets from Vault KV via
data "vault_kv_secret_v2" instead of SOPS var-file
- Add dependency "vault" to all migrated stacks' terragrunt.hcl
- Complex types (maps/lists) stored as JSON strings, decoded with
jsondecode() in locals blocks
Bootstrap secrets (vault_root_token, vault_authentik_client_id,
vault_authentik_client_secret) remain in SOPS permanently.
Apply order: vault stack first (populates KV), then all others.
