deploy(fc-llm-bridge): roll fc:vision image v202604300022

Source: FlowerCore.LlmBridge@8dd181c (feat: fc:vision route + image
content forwarding). Adds:

- fc:vision tier alias parsing (TryParseTier handles fc:vision,
  FC:VISION, openai/fc:vision, vision)
- Image content forwarding: OpenAi image_url shape (https URL +
  data:[mediaType];base64,... URI) and Anthropic image/source
  passthrough are now promoted to LlmContentBlocks. Text-only
  content-parts arrays still flatten to the legacy joined string.
- DefaultRoutes seeder + appsettings.json gain Vision -> Anthropic +
  claude-sonnet-4-6.

Image built on BLUEJAY-WS, podman save + ctr import to all 3 RKE2
nodes (rke2-server, rke2-agent1, rke2-agent2). Bridge tests: 62/62
green (was 51/51, +11). Backwards-compatible with current chat /
util / embed callers; existing routes unchanged.

+# knowledge — FlowerCore.Knowledge.Web (Phase 2.4 K8s deploy)
+
+**Status:** **LIVE 2026-04-27** at `https://knowledge.iamworkin.lan` —
+Phase 2.4 closed. Pod running, certificate issued (step-ca-acme), PVC
+bound (Longhorn 20Gi RWO), ArgoCD `infra-knowledge` synced. `/healthz`
+returns 200, `/api/v1/editions` returns `[]` (initial-deploy state — no
+*.db files in the PVC yet; Phase 2.5+ admin UI handles bulk
+population). Phase 1 of the Agent Zero MCP rollout keeps `/healthz`
+anonymous and gates `/mcp` behind `Authorization: Bearer <token>` built
+from the 1Password item `FlowerCore Knowledge MCP Tokens`.
+
+- Plan: [`../../../FlowerCore.Notes/docs/ai-agents/flowercore-knowledge-service-plan.md`](../../../FlowerCore.Notes/docs/ai-agents/flowercore-knowledge-service-plan.md)
+- Sprint: [`../../../FlowerCore.Notes/docs/ai-station/sprint-e-xxl-plan.md`](../../../FlowerCore.Notes/docs/ai-station/sprint-e-xxl-plan.md) (Track B)
+- Repo: `D:\git\FlowerCore\FlowerCore.Knowledge\` (private GitHub repo,
+  bootstrapped Sprint D batch 35)
+
+`FlowerCore.Knowledge.Web` is the fleet-wide vector-indexing & RAG hub —
+a REST + MCP service that scans `*.db` files under
+`/data/vector-stores` and exposes per-edition reachability + corpus
+search to the rest of the FC ecosystem (Agent Zero, Chat.Web persona
+memory, AiStation embeddings explorer, TtsReader chapter context, BMO
+bot, Pi nodes via `fc-index sync`).
+
+Phase 1 MCP routing is explicit:
+
+- in-cluster Agent Zero → `http://knowledge-web.knowledge.svc/mcp`
+- workstation Agent Zero → `https://knowledge.iamworkin.lan/mcp`
+- probe URL for both lanes → `/healthz`
+
+## Deployment order (do NOT skip / reorder)
+
+### 1. FlowerCore.DNS public A record — knowledge.iamworkin.lan -> 10.0.56.200
+
+Required BEFORE the Certificate resource is created, or cert-manager
+HTTP-01 silently backs off ~2h. Memory: `feedback_pfsense_dns_required_for_acme`.
+
+The canonical path is FlowerCore.DNS:
+
+```bash
+curl -sk https://dns.iamworkin.lan/api/v1/servers
+# Find the pfSense serverId, then create the record using the host label only.
+
+curl -sk -X POST https://dns.iamworkin.lan/api/v1/servers/<serverId>/zones/iamworkin.lan/records \
+  -H "Content-Type: application/json" \
+  -d '{"name":"knowledge","type":"A","data":"10.0.56.200","ttl":300}'
+```
+
+If FlowerCore.DNS provider writes are failing 502 with "pfSense
+diag_command.php response did not contain a `<pre>` block" (status as of
+Sprint E Track B authoring 2026-04-27), add the override manually via
+the pfSense web UI:
+
+1. Log in to `https://10.0.56.1` as admin
+2. Services → DNS Resolver → General Settings → Host Overrides
+3. Add: Host=`knowledge`, Domain=`iamworkin.lan`, IP Address=`10.0.56.200`
+4. Save + Apply Changes
+
+Verify resolution from anywhere on LAN:
+
+```bash
+nslookup knowledge.iamworkin.lan 10.0.56.1
+# Expect: 10.0.56.200
+```
+
+Or against FlowerCore.DNS once the provider is fixed:
+
+```bash
+curl -sk "https://dns.iamworkin.lan/api/v1/zones/iamworkin.lan/resolve-preflight?hostname=knowledge.iamworkin.lan"
+# Expect: "resolvable": true
+```
+
+### 2. Build + import the image to ALL RKE2 nodes
+
+Pods may schedule on any RKE2 worker (server, agent1, agent2). The
+Longhorn PVC accepts mounts from any node, so the image must be
+imported to all three. Memory:
+`feedback_rke2_image_import_targets_all_nodes` +
+`feedback_rke2_localhost_imagepullpolicy`.
+
+```bash
+# From BLUEJAY-WS, in D:\git\FlowerCore\FlowerCore.Knowledge
+TAG="v$(date +%Y%m%d%H%M)"
+dotnet.exe publish -c Release -o deploy/app \
+  src/FlowerCore.Knowledge.Web/FlowerCore.Knowledge.Web.csproj
+podman build -t localhost/fc-knowledge-web:$TAG -f deploy/Dockerfile.deploy deploy
+podman save localhost/fc-knowledge-web:$TAG -o /tmp/fc-knowledge-web.tar
+
+# Import to all three RKE2 nodes
+for node in rke2-server rke2-agent1 rke2-agent2; do
+  scp /tmp/fc-knowledge-web.tar $node:/tmp/
+  ssh $node "sudo /var/lib/rancher/rke2/bin/ctr -a /run/k3s/containerd/containerd.sock -n k8s.io images import /tmp/fc-knowledge-web.tar"
+done
+```
+
+The repo's `scripts/deploy-knowledge.sh` automates this loop.
+
+### 3. Bump the image tag + push
+
+Edit `knowledge.yaml`, replace `localhost/fc-knowledge-web:v202604272200`
+with the tag from step 2, then:
+
+```bash
+cd D:/git/FlowerCore/bluejay-infra
+python scripts/check-pfsense-dns.py     # confirms the DNS preflight
+git add apps/knowledge/
+git commit -m "feat(knowledge): deploy Phase 2.4 K8s manifest"
+git push
+```
+
+ArgoCD picks up within ~3 minutes and creates `infra-knowledge`.
+
+### 4. Verify
+
+```bash
+fcadmin_ssh noc1 '
+  kubectl -n argocd get application infra-knowledge
+  kubectl -n knowledge get certificate,pod,pvc
+  curl -sk -m 8 -o /dev/null -w "HTTP %{http_code}\n" https://knowledge.iamworkin.lan/healthz
+  curl -sk -m 8 https://knowledge.iamworkin.lan/api/v1/editions | jq
+'
+```
+
+Expect: Certificate `Ready: True` within ~60s, `/healthz` HTTP 200,
+`/api/v1/editions` returns an empty array (no DBs in the PVC yet) on
+first deploy.
+
+## Initial-deploy state and Phase 2.5 follow-up
+
+The Longhorn PVC is empty on first deploy. Knowledge.Web's filesystem
+catalog will report zero editions until vector-store `*.db` files are
+pushed into `/data/vector-stores`. Initial population is a follow-up
+step (Phase 2.5+, Blazor admin UI's "Rebuild" button); for the first
+deploy the goal is just to prove the pod boots, `/healthz` returns 200,
+and the Traefik IngressRoute serves the Scalar UI.
+
+To copy an existing local DB into the PVC (one-time, manual until
+Phase 2.5 admin UI lands):
+
+```bash
+fcadmin_ssh noc1 '
+  POD=$(kubectl -n knowledge get pod -l app=knowledge-web -o jsonpath="{.items[0].metadata.name}")
+  kubectl -n knowledge cp /var/lib/flowercore/vector-stores/bluejay-ai.db $POD:/data/vector-stores/bluejay-ai.db
+'
+```
+
+## Probes + middleware notes
+
+- `/healthz` is mapped by `Controllers/HealthController.cs` (controller-based
+  attribute route). Cheap — no DB, no dependencies.
+- Liveness uses `tcpSocket` as a defensive fallback in case future
+  middleware accidentally gates `/healthz` behind auth (memory:
+  `feedback_k8s_probes_behind_auth_middleware`).
+- `/openapi/v1.json` and `/scalar/v1` are wired by `UseFlowerCoreApi`.
+  Per memory `feedback_k8s_probes_must_not_hit_openapi`, probes must NOT
+  point at OpenAPI documents — the `MapOpenApi` call can be slow during
+  cold startup.
+
+## Resource sizing
+
+- 256Mi memory request / 1Gi limit.
+- 100m CPU request / 1000m limit.
+- 20Gi Longhorn PVC initial — sufficient for the bluejay-ai 1.94Gi DB +
+  fleet-pi-edge 352Mi + fleet-bmo-bot 141Mi + headroom. Resize via
+  `kubectl -n knowledge edit pvc knowledge-vector-store` if growing
+  past 15Gi.
