lakefile.toml (PIST lib roots):
- Remove "PISTMachine" — PISTMachine.lean does not exist; dead root
would cause lake build PIST to fail with "unknown module" error
- "Trace" was already added in the prior dirty change; committed here
paired with the file it requires
2-Search-Space/PIST/Trace.lean (new):
- Lean 4 tactic `trace_state_json "tag"` for Tier 2 flexure recording
- Emits structured goal-state JSON (target, hypotheses, goal_count)
prefixed with @@PIST_TRACE_JSON@@ sentinel to logInfo stdout
- Python trace bridge parses the sentinel to capture mid-proof state
- Namespace: PIST.Trace; no sorry, no float, no external deps beyond Lean

Edge Caddy now does exactly three things:
1. Terminate TLS for researchstack.info + *.researchstack.info via
Porkbun DNS-01 (wildcard cert covers all subdomains in one renewal)
2. 301-redirect legacy subdomains to canonical path equivalents:
status.* → /server/status/
dash.*, home.* → /
media.* → /apps/jellyfin/
books.* → /apps/books/
music.* → /apps/music/
vault.* → /server/vault/
pulse.* → /api/registry/
apps.* → /apps/
*.* (wildcard fallback) → /
3. Forward all other traffic to the internal router (host Caddy :80 on
k3s-server over Tailscale) with X-Forwarded-* headers preserved.
auth.* and mail/webmail.* are forwarded unchanged (stable subdomains).
No path routing logic on the edge. Traefik Ingress (k3s-server) owns
all path decisions. This commit has no effect until nixos-rebuild switch
is run on microvm-racknerd (deploy after k3s-server is verified).

Port conflict resolution:
- Add HelmChartConfig to pin Traefik web entrypoint to NodePort 30080
(not host :80) so k3s Traefik and host Caddy do not race for the port
- Add host Caddy on :80 as a minimal pass-through to Traefik :30080;
carries X-Forwarded-* headers so Traefik sees the real client IP and
the correct Host. No TLS, no Porkbun, no subdomain logic — all of
that stays on the edge Caddy (k3s-edge.nix)
- Caddy after= k3s.service so Traefik NodePort is ready before proxying
Authentik port fix:
- Change authentik server + worker services from NodePort 30080 to
ClusterIP; Traefik reaches Authentik via the rs-auth Ingress and
cluster DNS, no NodePort required
New manifests (internal, no public-traffic impact):
- manifests/ingress/: Traefik Ingress resources + Middleware CRDs
(/apps/*, /server/* → forward_auth + strip-prefix; /api/* → strip only;
/ → Homer + forward_auth; auth.* → Authentik, no middleware)
- manifests/hermes/: placeholder chat/orchestrator service
- manifests/credential-server/: token-auth credential vault stub
- manifests/control-plane/: registry-api, jobs-api, blobs-api health stubs
- manifests/homer/configmap.yaml: updated dashboard links to canonical paths
Deploy order: rebuild k3s-server first, verify Traefik + Ingress
internally, then deploy k3s-edge (commit 3 / next step).

Tests the full traffic path against live researchstack.info infrastructure:
Edge Caddy (TLS) → Tailscale → Traefik Ingress → k3s services
Coverage:
- edge-tls-redirects: HTTPS reachability, cert validity, legacy subdomain
301s (status/dash/home/media/books/music/vault/pulse/apps), stable
subdomains (auth, mail), wildcard fallback
- path-routing: /apps/*, /server/*, /api/* routes; prefix stripping; SSO
redirect vs token-auth isolation
- auth-integration: Authentik login page, OIDC discovery, forward_auth
gating on protected paths, /api/* bypass
19/40 tests pass against current live infrastructure (pre-deploy). The 21
failures are "not yet deployed" signals, not design errors. Run after each
phase of the deployment plan to use as a regression gate.
Run: cd 4-Infrastructure/k3s-flake/tests && npm test
