fix(P1): recompute TARBALL after fallback version walk (REQ-132)

The fallback walk (REQ-098) reassigns VERSION from the requested
release to the nearest older release carrying a binary asset, but
never recomputed TARBALL (set once at line 106 from the requested
version). The stale tarball name then flowed into:

  - grep -F "$TARBALL" SHA256SUMS  -> matched nothing (the fallback
    release's SHA256SUMS only lists the fallback tarball)
  - sha256sum -c -                 -> empty stdin -> "no properly
    formatted checksum lines found" -> REQ-132 refusal
  - tar -xzf "${TMPDIR}/${TARBALL}" -> would look for the wrong
    filename (download saved under the stale name too)

User-visible symptom (v0.14.2 latest had no asset, fell back to
v0.12.18):

  install: verifying checksum...
  sha256sum: 'standard input': no properly formatted checksum lines found
  install: error: checksum verification failed (REQ-132); refusing to install

Fix: recompute TARBALL immediately after VERSION is reassigned in the
fallback branch, so download/grep/sha256sum/tar all reference the
fallback version's tarball. ASSET_URL and SHA256SUMS_URL were already
correct (derived from the API/ASSET_URL); TARBALL was the only stale
variable.

Reproduced the exact error before the fix; confirmed end-to-end
install succeeds after (orca-v0.12.18-linux-amd64.tar.gz: OK ->
extracting -> installed). Added a bats regression test pinning
--version v0.14.2 and asserting the dry-run "would install" line
references the fallback version (not the stale pinned one).

    decision: Recompute TARBALL in the fallback branch immediately
      after VERSION is reassigned, so grep/sha256sum/tar use the
      fallback version's filename instead of the stale requested
      version's.
    rationale: Reproduced the exact user error ("no properly formatted
      checksum lines found") by running grep -F "$TARBALL" SHA256SUMS
      | sha256sum -c with a stale v0.14.2 tarball name against v0.12.18
      SHA256SUMS. TARBALL is the only stale variable: ASSET_URL and
      VERSION are correctly updated from API output, and SHA256SUMS_URL
      derives from ASSET_URL. Single-line fix, minimal blast radius,
      preserves the working non-fallback path.
    confidence: 0.96
    alternatives:
      - lazy TARBALL via a function (over-engineering for one stale
        assignment)
      - move TARBALL= assignment past the fallback block (breaks
        find_asset_url which needs the requested version's name
        pre-walk)
lessons:
  - When a fallback/walk mutates one variable (VERSION), audit every
    variable derived from it (TARBALL) for the same mutation. The
    user-facing info line at 167 constructed the name inline and
    looked correct, masking that the variable itself was stale.

+## v0.14 Deltas — Ingress Bootstrap Completeness (R-024)
+
+### R-024: Traefik as Podman Container
+
+Traefik runs exclusively as a podman container, deployed from the
+custom `orca-traefik` image (published per release via `Dockerfile.traefik`
++ `scripts/release.sh` + `.coreci.yml container-publish-traefik`).
+
+The v0.13 binary+systemd install (`internal/traefik/install.go`) is
+replaced by an idempotent podman container reconciler
+(`EnsureTraefikContainerLocal`/`Remote`). The container runs with
+`--network host`, `--restart=unless-stopped`, and volume mounts for
+`traefik.yml` (static config), `dynamic` (dynamic config), and
+`step-ca-root.crt` (future mTLS). No SELinux `:Z` flag.
+
+### Three Ingress Topologies
+
+1. **Linux** (`orca init` / `orca node join --type linux`):
+   host → nft DNAT → podman traefik (host network).
+   `internal/ingress/bootstrap.go` → `BootstrapLocalIngress` /
+   `BootstrapRemoteIngress`.
+
+2. **Proxmox Native** (`--ingress-mode native`, default):
+   PVE host → nft DNAT (target = LXC bridge IP) → LXC
+   (`--features nesting=1,keyctl=1,fuse=1`) → podman traefik.
+   `internal/proxmox/bootstrap.go` → `provisionNativeIngressLXC`.
+
+3. **Proxmox Floating-IP** (`--ingress-mode floating-ip`):
+   LXC owns the floating IP (`net0 bridge=vmbr0,hwaddr=<mac>,
+   ip=<floating-ip>/<prefix>,gw=<gateway>`) → nft inside LXC →
+   podman traefik. The ingress LXC is registered as a `linux` node
+   (name=`ingress`) so `orca job run` pushes traefik dynamic config.
+   `internal/proxmox/ingress_lxc.go` → `ProvisionIngressLXC`.
+
+### nft Emitter Changes
+
+`internal/emitter/nft.go`:
+- `DNATTarget` field (C-51: validated via `net.ParseIP`). Default
+  `127.0.0.1`; proxmox native uses LXC bridge IP.
+- `EnableSNAT` field + postrouting masquerade chain: `ip saddr
+  127.0.0.0/8 oifname != "lo" masquerade` (research Topic 1).
+- Input/forward chain priority shifted from `filter` (=0) to `-10`
+  (research Topic 2: pve-firewall coexistence — avoids same-priority
+  undefined evaluation order).
+
+### TLS Model
+
+v0.14 drops `certResolver: orca` from the dynamic config (traefik v3.3
+only supports `acme`/`tailscale` resolvers, not CA-file-based). The
+dynamic config emits `tls: {}` (traefik default cert). Real mTLS via
+`tls.certificates` + `tls.options.default.clientAuth.caFiles` is
+deferred to v0.15 (grill G-003, confidence 0.55 < 0.60).
+
+### Migration 0009
+
+`ALTER TABLE nodes ADD COLUMN ingress_mode TEXT NOT NULL DEFAULT '';`
+Values: `""` (legacy), `"native"`, `"floating-ip"`. `IngressMode` field
+on `model.Node`.
+
+### New CLI
+
+- `orca doctor ingress` — verifies podman container running, nft
+  DNAT+SNAT, dynamic dir, step-ca root CA.
+- `--ingress-mode` flag on `orca node join --type proxmox`.
+- `--floating-ip`, `--gateway`, `--mac`, `--net-prefix` flags for
+  floating-IP mode.

+# CLARIFY v0.14: Ingress Bootstrap Completeness
+
+**Autonomy**: full (config `autonomy.level = "full"`)
+**Budget**: 10 questions (used: 5 interactive, 5 auto-resolved)
+**Result**: all ambiguities resolved; 9 decisions (D-255..D-263) recorded in PROJECT.md
+
+## Interactive Questions (resolved with operator)
+
+### Q1: iptables vs nft emitter
+**Ambiguity**: Codebase is nft-only (D-218). Operator said "iptables used for SNAT/DNAT".
+**Resolution**: D-255 (partial) — Extend the existing nft emitter (`internal/emitter/nft.go`) with SNAT/MASQUERADE postrouting rules. "iptables" in the operator's description is read as "kernel NAT" — nft is the modern backend. No literal iptables emitter.
+**Confidence**: 0.95
+
+### Q2: ingress LXC lifecycle
+**Ambiguity**: Should the floating-IP LXC be registered as an orca-managed node or left as a one-shot external proxy?
+**Resolution**: D-259 — Register as a managed `linux` node (name=`ingress`, addr=`<floating-ip>:8443`). `orca job run` pushes traefik dynamic config to it like any linux node. This makes routing-to-other-hosts work.
+**Confidence**: 0.92
+
+### Q3: Floating-IP network topology
+**Ambiguity**: Where does SNAT run and how does the LXC get the public IP?
+**Resolution**: LXC owns floating IP on eth0 (`net0 bridge=vmbr0,hwaddr=<mac>,ip=<floating-ip>/<prefix>,gw=<gateway>`). nft runs inside the LXC. Matches Hetzner/OVH floating-IP-with-MAC model.
+**Confidence**: 0.90
+
+### Q4: TLS cert resolver in the image
+**Ambiguity**: The emitted static config references `certResolver: orca` but never declares the `certificatesResolvers.orca` block. v0.11 claimed P10 would wire step-ca but it was never implemented.
+**Resolution**: D-257 — Bake a `certificatesResolvers.orca.tls: { }` block pointing at a mounted `/etc/orca/step-ca-root.crt` CA file. No ACME (offline-first, R-001). If the file is absent at start, traefik logs a warning and serves plain HTTP (graceful degradation). The orca bootstrap pushes the cluster root CA into the container volume.
+**Confidence**: 0.90
+
+### Q5: Container networking
+**Ambiguity**: nft DNAT targets 127.0.0.1:8080/8443 on the host. How does the podman container receive that traffic?
+**Resolution**: D-256 — `--network host` so traefik binds 127.0.0.1:8080/8443 directly on the host (or LXC) loopback. No container port publishing. Simplest, matches the hybrid R-017 model.
+**Confidence**: 0.92
+
+### Q6: Dynamic config volume strategy
+**Ambiguity**: How does the podman traefik container consume dynamic config? Today `orca job run` writes `/etc/traefik/dynamic/orca-<svc>.yaml` on the host.
+**Resolution**: D-258 — Mount `/etc/traefik/dynamic` from host (`-v /etc/traefik/dynamic:/etc/traefik/dynamic:Z`). Zero changes to the existing `deployRemote` WriteFile path. The image's file provider watches `/etc/traefik/dynamic` as today.
+**Confidence**: 0.95
+
+## Auto-resolved questions (full autonomy, no operator interaction)
+
+### Q7: Floating-IP mode — does the PVE host also register as a node?
+**Ambiguity**: In floating-IP mode, only the ingress LXC handles traffic. Does the PVE host also get registered?
+**Resolution**: D-259 — Yes. The PVE host registers as a `proxmox` node (for `pct`/`qm` workload dispatch). The ingress LXC registers as a `linux` node (for traefik dynamic config pushes). Both are in the registry.
+**Confidence**: 0.92
+
+### Q8: `--ingress-mode` persistence
+**Ambiguity**: Should `--ingress-mode` be stored on the node record so `doctor ingress` knows which check path to run?
+**Resolution**: D-260 — Yes. Add `IngressMode` field to `model.Node` + a schema migration (0007). Values: `""` (legacy/default for linux/localhost), `"native"`, `"floating-ip"`.
+**Confidence**: 0.90
+
+### Q9: MAC generation when `--mac` omitted
+**Ambiguity**: In floating-IP mode, if `--mac` is not provided, should orca generate one or require it?
+**Resolution**: D-261 — Interactive mode: generate a random locally-administered MAC (`02:XX:XX:XX:XX:XX`) and print it for operator confirmation. `--json` mode: require `--mac` explicitly (no silent generation — non-interactive means explicit inputs).
+**Confidence**: 0.88
+
+### Q10: Proxmox native nft DNAT target
+**Ambiguity**: In native mode, traefik runs inside an LXC. LXC has its own network namespace. nft DNAT to `127.0.0.1:8443` on the PVE host would NOT reach a container inside an LXC (different loopback). What's the DNAT target?
+**Resolution**: D-262 — The nft DNAT target is parameterized via `NftClusterConfig.DNATTarget` (default `127.0.0.1:8443`). For proxmox native mode, the DNAT target is the LXC's bridge IP (`<lxc-ip>:8443`). The LXC gets a DHCP/static bridge IP; orca discovers it after `pct start` via `pct list` or `pct inspect`.
+**Confidence**: 0.90
+
+## Additional decisions (derived from constraints, no ambiguity)
+
+### D-263: LXC podman requirements
+Ubuntu 24.04 LXC template does not have podman preinstalled. Bootstrap must:
+1. `pct create` with `--features nesting=1,keyctl=1` (required for podman in unprivileged LXC)
+2. After LXC start: `apt-get update && apt-get install -y podman nftables` inside the LXC
+3. Then `podman pull orca-traefik:<tag>` + `podman run ...`
+
+This adds ~30-60s to the join time. Documented in `docs/uat.md`.
+
+### Image tag strategy
+The `orca-traefik` image uses the same version tag as the orca release (`v0.13.x` line). The podman reconciler resolves the tag from `internal/cli.version`. In dev builds (version="dev"), it falls back to `latest`.
+
+### Registry auth
+The `orca-traefik` image is in the same registry/org as `orca` (`git.cloudinit.dev/coreci/`). Pulls are anonymous (REQ-045, repo is public). No `podman login` needed on workers.
+
+## Requirements impact
+
+No new requirements beyond REQ-171..REQ-179 (already in REQUIREMENTS.md). The clarify stage confirmed scope and resolved all implementation ambiguities. The 9 decisions (D-255..D-263) are recorded in PROJECT.md.

+# CLARIFY + RESEARCH + PLAN v0.15: CI Release Pipeline Fix
+
+## Decisions
+
+| ID | Decision | Rationale | Confidence |
+|----|----------|-----------|------------|
+| D-264 | Secret name = `PAT_TOKEN` (not `GITEA_PAT`) | Gitea reserves `GITEA_` prefix for built-in secrets | 1.0 (validated) |
+| D-265 | Use `tea actions secrets create` CLI | Operator instruction: no API | 1.0 (validated) |
+| D-266 | Container publishing in Gitea Actions, not CoreCI | CoreCI's podman executor appends `sh -c` which conflicts with kaniko's `/kaniko/executor` entrypoint. Gitea Actions `container:` supports `options: --entrypoint` | 0.95 |
+| D-267 | kaniko `executor:debug` image | Includes `/bin/sh`; Gitea Actions can override entrypoint to `/bin/sh` then run kaniko via shell | 0.90 |
+| D-268 | `coreci run` for validate/build/test/release (tarball); Gitea Actions for container publishing | Clean separation: CoreCI owns the pipeline, Gitea Actions owns the trigger + container publish | 0.95 |
+
+## Research: CoreCI podman executor entrypoint issue
+
+CoreCI's `internal/runner/podman_executor.go:48-51`:
+```go
+args = append(args, image)  // e.g. gcr.io/kaniko-project/executor:debug
+if job.Invoke != "" {
+    args = append(args, "sh", "-c", job.Invoke)
+}
+```
+This produces: `podman run ... <image> sh -c "<commands>"`
+With kaniko:debug (entrypoint `/kaniko/executor`), the actual command is:
+`/kaniko/executor sh -c "<commands>"` — kaniko fails (sh is not a kaniko flag).
+
+**Conclusion**: kaniko cannot be used as a CoreCI step image. Container
+publishing must move to the Gitea Actions workflow, which supports
+`container: options: --entrypoint /bin/sh` to override the entrypoint.
+
+## Plan
+
+### Phase 1 (only execution phase)
+
+**Files to create/modify:**
+
+1. `.gitea/workflows/release.yml` — Gitea Actions workflow:
+   - `on: push: tags: ['v*']`
+   - Job 1 `ci`: checkout + install Go + install coreci + `coreci run`
+     (executes validate/build/test/release from .coreci.yml)
+   - Job 2 `container-orca`: checkout + kaniko build+push orca image
+     (needs job 1; uses `container: gcr.io/kaniko-project/executor:debug`
+     with `options: --entrypoint /bin/sh`)
+   - Job 3 `container-traefik`: checkout + kaniko build+push orca-traefik image
+     (needs job 1; same kaniko approach)
+
+2. `.coreci.yml` — remove `container-publish` and `container-publish-traefik`
+   steps (they now live in the Gitea Actions workflow). Keep the
+   `gitea-release` step (tarball + Gitea release).
+
+3. `scripts/trigger_coreci.sh` — add tag ref handling (or document that
+   Gitea Actions is the trigger; the hook is for branch-push CI only).

+# GRILL v0.14: Ingress Bootstrap Completeness — Red-Team Review
+
+**Date**: 2026-08-10
+**Reviewer**: ci-griller (adversarial)
+**Subject**: PLAN_v0.14.md (9 phases, P0–P8)
+**Confidence in plan as-written**: **0.45 — RETHINK** (was Proceed-eligible until the mTLS scope expansion was chosen)
+**Verdict**: **RETHINK** — the plan is technically grounded in strong research but contains (a) one outright correctness defect that will break execution, (b) two requirements/plan contradictions that ship broken config, (c) one scope expansion chosen during this grill that adds a 10th phase the plan does not contain, and (d) one regression of a Completed requirement. The research is the strongest artifact; the plan diverges from it in load-bearing ways.
+
+---
+
+## How this grill was conducted
+
+Every plan claim was checked against the actual codebase (`internal/traefik/install.go`, `internal/emitter/nft.go`, `internal/emitter/traefik.go`, `internal/cli/init.go`, `internal/cli/upgrade.go`, `internal/cli/doctor_nft.go`, `internal/proxmox/bootstrap.go`, `internal/linux/bootstrap.go`, `internal/store/migrations/`, `internal/certpaths/`, `internal/sshpush/`, `scripts/release.sh`, `.coreci.yml`, `Dockerfile`, git tags, git log). Findings cite file:line. Four binding questions were asked interactively; answers recorded as G-001..G-004 below.
+
+---
+
+## Per-Axis Findings
+
+### Axis 1 — Feasibility
+
+**Finding F1.1 (BLOCKER — migration number collision).** PLAN P5 T3 (line 194) specifies "Schema migration 0007: `ALTER TABLE nodes ADD COLUMN ingress_mode TEXT DEFAULT ''`". Migration 0007 **already exists** — `internal/store/migrations/0007_certs_serial_unique.sql` (added v0.7, P1-001). The current head is `0008_audit_tamper_evidence.sql`. The migrator runs files in lexical order and records applied versions in `schema_migrations`. Reusing 0007 will either (a) silently no-op on DBs that already recorded 0007, leaving `ingress_mode` un-added, or (b) break the migration ledger. This is a guaranteed execution-time defect.
+**Evidence**: `internal/store/migrations/0007_certs_serial_unique.sql`, `internal/store/migrations/0008_audit_tamper_evidence.sql`, `internal/cli/init_test.go:84` (test asserts head = 0008).
+**Resolved by**: G-001 (use `0009_ingress_mode.sql`).
+
+**Finding F1.2 (BLOCKER — `certpaths.CAPath()` does not exist).** PLAN P3 T5 step 2 (line 142) says "Push cluster root CA … from `certpaths.CAPath()` if exists". The function `certpaths.CAPath()` does not exist. The real API is `certpaths.CACertPath()` (`internal/certpaths/certpaths.go:35`) and `certpaths.CAKeyPath()` (`:39`). P4 T1 step 2 repeats the same phantom reference. This will not compile.
+**Evidence**: `internal/certpaths/certpaths.go:35` (`func CACertPath() string`); grep for `CAPath` returns zero matches in `internal/certpaths/`.
+
+**Finding F1.3 (no `install_test.go` to rewrite).** PLAN P2 T10 (line 112) says "rewrite `internal/traefik/install_test.go`". That file does not exist — `internal/traefik/` contains only `install.go` (glob confirms). The task is "create", not "rewrite". Minor, but signals the plan was written against an imagined codebase shape, not the real one.
+**Evidence**: `glob internal/traefik/*.go` → only `install.go`.
+
+**Finding F1.4 (good — fake-SSH harness exists and is adequate).** PLAN P7 T8 claims a "hermetic fake-SSH harness" can assert `pct create` + `podman run` inside LXC. Verified: `internal/proxmox/ssh_session_test.go:23` (`fakeSSHServer`) and `internal/sshpush/transport_test.go:27` implement an in-process SSH server with `runCommand(cmd)` pattern-matching. It can assert the right commands are *sent* (e.g. `pct create … --features nesting=1,keyctl=1,fuse=1`). It cannot actually create an LXC or run podman — but the plan only claims command assertion, which is achievable. The harness is real and reusable.
+
+**Finding F1.5 (good — callsites verified).** PLAN P2 T3/T4/T5 reference `init.go:254-266`, `linux/bootstrap.go:160-172`, `proxmox/bootstrap.go:250-255`. Verified: `init.go:256` calls `installTraefikLocal()`; `linux/bootstrap.go:170` calls `traefik.InstallRemote("", sshExecFn)`; `proxmox/bootstrap.go:253` calls `traefik.InstallRemote("", runRemote)`. The line numbers are accurate within a few lines. The plan was written against the real callsites.
+
+### Axis 2 — Scope
+
+**Finding F2.1 (BLOCKER — mTLS scope expansion chosen, no phase exists).** During this grill (G-003) the operator chose "Wire real mTLS now" over the plan's `tls: {}` default-cert approach. This requires step-ca to mint server certs into `/etc/traefik/dynamic` + dynamic `tls.certificates` + `tls.options.default.clientAuth.caFiles`. **Step-ca server-cert minting was deferred since v0.11 and is not implemented.** The 9-phase plan contains no such phase. The operator then chose (G-004-adjacent) to add a step-ca cert minting phase, growing v0.14 from 9 to 10 phases. The plan as written does not reflect this. Until a P-step for cert minting is added, the plan is incomplete relative to the chosen direction.
+**Impact**: v0.14 cannot ship real mTLS on its current 9 phases. Either add the phase (10 phases, more risk) or revert to `tls: {}` and defer mTLS to v0.15.
+
+**Finding F2.2 (regression — `traefik-on-public-ip` opt-out lost).** REQ-100 (Complete, v0.11) established the `--public-binding=traefik-on-public-ip` opt-out: traefik binds `:443`/`:80` directly instead of `127.0.0.1:8443`/`8080` + nft DNAT. The existing `RenderTraefikStaticConfig` (`internal/emitter/traefik.go:273`) implements this via `TraefikStaticOpts.PublicBinding`. The v0.14 plan's baked image (`docker/orca-traefik/traefik.yml`, PLAN lines 33-37) hard-codes `127.0.0.1:8443`/`8080` — there is no opt-out path in the image. Baking the static config into the image freezes out the opt-out mode that v0.11 shipped. This is a regression of a Completed requirement.
+**Evidence**: `internal/emitter/traefik.go:255-266` (`publicWebSecure`/`publicWeb` switch on `PublicBinding`); `internal/emitter/traefik.go:282-300` (rendered static config); REQUIREMENTS REQ-100 line 218.
+
+**Finding F2.3 (9 phases is borderline; 10 is too many).** Even before the mTLS expansion, 9 phases for an "ingress bootstrap completeness" milestone is heavy. P5 (proxmox native) and P6 (floating-IP) are the two most complex (LXC creation + podman-in-LXC + apt-get + nft-inside-LXC). They could potentially be merged into one phase with two code paths, since they share `ProvisionIngressLXC` plumbing. With the mTLS expansion, 10 phases is too many for a single milestone — split v0.14 into v0.14a (linux ingress + mTLS) and v0.14b (proxmox ingress).
+
+**Finding F2.4 (good — research-validated decisions are sound).** The 7 research topics (nft postrouting, pve-firewall priority, LXC features, traefik Dockerfile, pct create syntax, podman restart, SELinux) are well-sourced and the recommended approaches are technically correct. This is the strongest artifact in the v0.14 dossier.
+
+### Axis 3 — Dependencies
+
+**Finding F3.1 (good — ordering is correct).** P1 (image) → P2 (reconciler) → P3 (nft+init) → P4 (remote linux) → P5 (proxmox native) → P6 (floating-IP) → P7 (doctor+tests) → P8 (ship). Each phase references the prior phase's output (P3 T6 calls `EnsureTraefikContainerLocal` from P2; P5 T4 step 10 calls `EnsureTraefikContainerRemote` from P2). No phase can ship before its prerequisite.
+
+**Finding F3.2 (hidden dependency — P2 T8 depends on P1 T1).** P2 T8 (drop `certResolver: orca`) edits `internal/emitter/traefik.go`. P1 T1 bakes the static config. The dynamic config (`traefik.go`) and static config (`docker/orca-traefik/traefik.yml`) must be consistent: if the static config has no `certificatesResolvers.orca` (P1 T1 correctly omits it) but the dynamic config still references `certResolver: orca` (until P2 T8), traefik logs a warning on every reload. The plan orders P1 before P2, so there is a window (P1 shipped, P2 not yet) where the published image + the live dynamic config are inconsistent. This is acceptable only if P1 and P2 ship in quick succession; if P1 stalls, the image is published with a known TLS-config mismatch.
+
+### Axis 4 — Security
+
+**Finding F4.1 (good — nft injection guard already present).** `internal/emitter/nft.go:104-130` (`partitionTrustedProbes`) validates every `TrustedProbes` entry as IP/CIDR before rendering (F9 guard). The v0.14 plan adds `DNATTarget` (P3 T1) — this is a NEW string field rendered directly into `dnat to <DNATTarget>:8443`. **The plan does not specify validation of `DNATTarget`.** If `DNATTarget` is user-controllable (via `--floating-ip` or cluster config), an unvalidated value is an nft-syntax injection vector. The existing F9 guard covers `TrustedProbes`; `DNATTarget` needs the same treatment.
+**Binding**: C-51 (see below).
+
+**Finding F4.2 (container escape surface — LXC nesting).** `--features nesting=1,keyctl=1,fuse=1` (P5/P6) is the documented requirement for podman-in-LXC, but nesting exposes host procfs/sysfs to the guest (Proxmox docs, RESEARCH Topic 3). This is an accepted tradeoff for container-in-container, but the plan does not document the threat-model acceptance. For a "production hardening" lineage, the ingress LXC is now a privileged-ish surface (nesting+keyctl) running a podman container pulling an image from a registry. The supply chain is: `git.cloudinit.dev/coreci/orca-traefik:<version>` (P1). If the registry is compromised or the tag is re-pushed, the ingress LXC runs attacker code at the host-LXC boundary. The plan has no image-signing/verification step (`podman pull --cert-dir` or cosign).
+**Binding**: C-52 (see below).
+
+**Finding F4.3 (nft rules injection via re-apply).** P3 T4 changes `flush table` to `delete table`. RESEARCH Topic 1 establishes that `delete table` on a missing table errors, and the fix is to pre-create the table (`nft add table inet orca-ingress 2>/dev/null || true`) before `nft -f`. P3 T5 step 4 does this. Good. But the re-apply path (P3 T5 step 5, P4 T1 step 5) runs `nft -f` which replaces the whole table — if a concurrent process (pve-firewall, operator) adds rules to `orca-ingress` between the pre-create and the `nft -f`, they are wiped. This is by design (orca owns the table) but should be documented as "orca is the sole owner of `table inet orca-ingress`".
+
+### Axis 5 — Operational
+
+**Finding F5.1 (BLOCKER — no upgrade path from v0.13 binary+systemd to v0.14 podman).** P2 T6 (line 104) says "update legacy cutover to pull new image + recreate container instead of sed-ing traefik.yml". But `internal/cli/upgrade.go:244-407` implements a Traefik `:443` → `127.0.0.1:8443` cutover that does `systemctl restart traefik` (line 382) — it restarts the **systemd service**, not a container. P2 removes systemd unit generation. There is **no phase** that: (a) detects the legacy `orca-traefik.service`, (b) stops+disables it, (c) removes `/usr/local/bin/traefik` + `/etc/systemd/system/orca-traefik.service`, (d) then runs `EnsureTraefikContainerLocal`. Without this, upgrading a live v0.13 cluster leaves a dead systemd unit AND a new podman container both trying to bind `127.0.0.1:8443` → port conflict, traefik down.
+**Resolved by**: G-004 (P2 T6 must remove legacy unit + binary, idempotent, tested).
+
+**Finding F5.2 (podman/podman-restart.service unavailable).** P2 T2 enables `podman-restart.service`. RESEARCH Topic 6 establishes this is not enabled by default on Ubuntu 24.04 and must be enabled. But the plan does not specify what happens if `podman` is not installed on the target host (a fresh linux node join, P4). `EnsureTraefikContainerLocal`/`Remote` calls `podman pull`/`podman run` — if `podman` is absent, this fails. The plan has no "install podman first" step for the linux topology (P3/P4). For proxmox (P5/P6) the plan installs podman via `apt-get install -y podman conmon crun fuse-overlayfs` inside the LXC (T4 step 4 / T1 step 6). But for linux nodes (P3/P4), there is no podman-install step. This is an under-specification.
+**Binding**: C-50 (see below).
+
+**Finding F5.3 (good — `--network host` is correct).** RESEARCH Topic 3 confirms `--network host` inside an LXC binds the LXC's netns, so traefik binds `127.0.0.1:8080/8443` on the LXC loopback and nft on the PVE host DNATs to the LXC IP. This is sound. The `DNATTarget` parameterization (D-262) correctly distinguishes `127.0.0.1` (linux/localhost) from `<lxc-ip>` (proxmox native).
+
+**Finding F5.4 (reboot persistence chain has a gap).** RESEARCH Topic 6 establishes the chain: Proxmox boot → `--onboot 1` starts LXC → LXC systemd starts → `podman-restart.service` restarts container. P5 T4 step 6 and P6 T1 step 8 enable `podman-restart.service` inside the LXC. But `--onboot 1` starts the LXC **after** the Proxmox host's network is up — if the floating IP is on a bridge that depends on a physical link that's slow to come up, the LXC may start before the bridge is ready, and the floating-IP `eth0` config may fail. The plan does not address LXC-start ordering relative to bridge readiness.
+
+### Axis 6 — Testing
+
+**Finding F6.1 (good — harness is real).** `fakeSSHServer` (Axis 1 F1.4) can assert `pct create` with the right `--features` and `net0` args, `apt-get install podman`, `podman run` with `--network host`. P7 T8's claims are achievable.
+
+**Finding F6.2 (gap — no test for the v0.13→v0.14 upgrade).** G-004 requires the upgrade path to be tested. The plan's P2 Wave 4 (T10) tests the reconciler but not the legacy-removal path. There is no test that: (a) simulates a host with `orca-traefik.service` present, (b) runs the upgrade, (c) asserts the unit is stopped+disabled+removed, (d) asserts the podman container is running. This must be added to P2 T10.
+
+**Finding F6.3 (gap — no test for DNATTarget validation).** F4.1 identifies `DNATTarget` as an injection vector. P3 T8 (nft_test) asserts `DNATTarget` substitution but does not specify a test for invalid `DNATTarget` values (e.g. `1.2.3.4:8443; flush ruleset`). The existing F9 guard test pattern should be extended.
+
+**Finding F6.4 (good — doctor_nft extension is incremental).** P3 T7 extends `doctor_nft.go`. The existing file (`internal/cli/doctor_nft.go`) is well-structured with `nftCheckResult` lines; adding postrouting/masquerade/DNATTarget assertions is straightforward.
+
+### Axis 7 — Performance
+
+**Finding F7.1 (apt-get install podman on every proxmox join — 30-60s).** CLARIFY D-263 acknowledges "~30-60s to the join time". P5 T4 step 4 and P6 T1 step 6 run `apt-get update && apt-get install -y podman conmon crun fuse-overlayfs nftables` inside the LXC on every join. This is acceptable for a one-time bootstrap but painful if re-run. The reconciler must be idempotent (skip if podman already installed). The plan does not specify an idempotency check for the apt-get step.
+**Binding**: C-53 (see below).
+
+**Finding F7.2 (image pull latency).** `podman pull orca-traefik:<tag>` (P2 T1 step 3, P5/P6) pulls from `git.cloudinit.dev/coreci/`. On a proxmox host behind a slow link, this can take 10-30s for a ~150MB traefik image. The plan has no pull-timeout. If the registry is unreachable (offline-first is R-001!), the pull fails and traefik never starts. **R-001 (offline-first) is violated**: the plan depends on a registry pull at bootstrap time. There is no "pre-pull" or "bundle image into the LXC template" fallback.
+**Binding**: C-54 (see below) — this is a tension with R-001 that the plan does not acknowledge.
+
+**Finding F7.3 (nft re-apply disruption).** `nft -f` replaces the table atomically (single transaction). Existing connections are NOT disrupted (conntrack holds them). New connections during the apply window (<1ms) may be dropped. This is acceptable. No finding.
+
+### Axis 8 — Cost
+
+**Finding F8.1 (2 images per release — sustainable).** P1 adds `orca-traefik` image alongside `orca`. `.coreci.yml` gets a `container-publish-traefik` step (P1 T5). `scripts/release.sh` gets a second docker block (P1 T4). The traefik image is small (~150MB, Alpine-based). Registry storage: 2 images × N releases. At v0.13.x cadence (8 tags), that's 16 image-tags per milestone. Sustainable for a private Gitea registry. No finding.
+
+**Finding F8.2 (good — release.sh extension is minimal).** P1 T4 adds ~8 lines to `scripts/release.sh` after line 212. Verified the insertion point (line 213 is end of existing docker block). Clean.
+
+### Axis 9 — Completeness (3 topologies)
+
+**Finding F9.1 (linux topology — covered by P3+P4).** `orca init` (P3) bootstraps nft+podman on the lead; `orca node join --type linux` (P4) does it remotely. Complete.
+
+**Finding F9.2 (proxmox-native — covered by P5, but LXC IP discovery is hand-wavy).** P5 T4 step 9 says "Discover LXC IP via `pct config <vmid>` (parse `net0` line) or `pct exec <vmid> -- hostname -I`". But in native mode the LXC is created **without** a static IP (P5 T4 step 2 has no `ip=` in the `pct create` — unlike P6 which has `ip=<floating-ip>/<prefix>`). So the LXC gets a DHCP/bridge IP that is not known at create time. P5 step 9 discovers it after `pct start`. But step 10 then re-applies nft with the discovered IP. This is a two-phase apply: first apply with default `127.0.0.1` (wrong for native), then re-apply with LXC IP. The plan does not specify what happens to traffic between the first and second apply (it DNATs to 127.0.0.1:8443 on the PVE host where nothing listens → connections refused). There is a window of ingress downtime during native-mode bootstrap.
+**Binding**: C-55 (see below).
+
+**Finding F9.3 (floating-IP — covered by P6, but MAC uniqueness is untested).** P6 T4 generates a random `02:XX:XX:XX:XX:XX` MAC in interactive mode. The plan does not check for MAC collision on the bridge. RESEARCH Topic 5 pitfall 2: "hwaddr must be unique on the bridge". A random 02: prefix has 46 bits of entropy — collision is unlikely on a single bridge but not impossible across a multi-node cluster.
+**Binding**: C-56 (see below).
+
+**Finding F9.4 (no `localhost`/lead topology with podman).** P3 bootstraps the lead via `EnsureTraefikContainerLocal`. But `orca init` runs on the lead — if the lead has no podman installed (fresh host), `EnsureTraefikContainerLocal` fails. Same as F5.2 but for the lead. The plan assumes podman is present on the lead. No install step.
+

+
+## Binding Conditions (gates that MUST be met before a phase ships)
+
+| ID | Gate | Phase | Severity |
+|----|------|-------|----------|
+| **C-50** | P2 must not break existing `orca init` on a host without podman installed — either install podman as part of `BootstrapLocalIngress` (P3) or emit a clear error with install instructions. Same for `orca node join --type linux` (P4). | P2/P3/P4 | BLOCKER |
+| **C-51** | `NftClusterConfig.DNATTarget` must be validated as `net.ParseIP` or `ip:port` before rendering. Unvalidated values are an nft-syntax injection vector (same F9 guard as TrustedProbes). Test required. | P3 | BLOCKER |
+| **C-52** | The `orca-traefik` image supply chain must be documented: registry is public (anonymous pull per REQ-045), no image signing in v0.14. Document the threat-model acceptance: a compromised registry = attacker code in the ingress LXC. Add `podman image trust` or cosign verification as a v0.15 hardening item. | P1/P8 | High |
+| **C-53** | The `apt-get install podman` step inside the LXC (P5 T4 step 4, P6 T1 step 6) must be idempotent: check `command -v podman` first, skip if present. Re-running join on an existing LXC must not re-run apt-get. | P5/P6 | High |
+| **C-54** | R-001 (offline-first) tension: `podman pull` at bootstrap requires registry reachability. Either (a) document that ingress bootstrap requires online access (exception to R-001), or (b) pre-bundle the `orca-traefik` image into the LXC template / load from a local archive. The plan must acknowledge this tension explicitly. | P2/P5/P6 | BLOCKER |
+| **C-55** | P5 native-mode bootstrap must not create a window of ingress downtime. The first nft apply must use the LXC IP (discovered after `pct start` but before the first nft apply), OR the plan must accept and document the downtime window. Two-phase apply (default → LXC IP) is a transient outage. | P5 | High |
+| **C-56** | P6 MAC generation must check for collision against existing nodes' MACs in the cluster registry. Reject or regenerate on collision. | P6 | Medium |
+| **C-57** | P2 T6 must implement the v0.13→v0.14 upgrade: detect `orca-traefik.service`, stop+disable, remove `/usr/local/bin/traefik` + unit file, then `EnsureTraefikContainerLocal`. Idempotent. Tested with a simulated-legacy-host test (F6.2). | P2 | BLOCKER |
+| **C-58** | The baked `docker/orca-traefik/traefik.yml` must not regress REQ-100's `traefik-on-public-ip` opt-out. Either (a) bake both configs and select via env/flag, or (b) document that the opt-out is dropped in v0.14 and update REQ-100, or (c) mount the static config from host (not baked) so `RenderTraefikStaticConfig` still works. | P1 | High |
+| **C-59** | Migration for `ingress_mode` must be `0009_ingress_mode.sql`, NOT 0007 (already taken by certs_serial_unique). | P5 | BLOCKER |
+| **C-60** | `certpaths.CAPath()` references in P3 T5 and P4 T1 must be corrected to `certpaths.CACertPath()`. | P3/P4 | BLOCKER (compile) |
+| **C-61** | REQ-172 must be amended: `--restart=always` → `--restart=unless-stopped` (per RESEARCH Topic 6 + PLAN), and `:Z` → omitted (per G-002). The requirement text contradicts the plan and research. | P2 | High |
+| **C-62** | If mTLS is in-scope for v0.14 (per G-003), a new phase must be added implementing step-ca server-cert minting into `/etc/traefik/dynamic` + dynamic `tls.certificates` + `tls.options.default.clientAuth.caFiles`. The plan currently has no such phase (P2 T8 emits `tls: {}`). | NEW PHASE | BLOCKER |
+
+---
+
+## Phase Challenges (specific challenges a phase must overcome)
+
+| ID | Challenge | Phase |
+|----|-----------|-------|
+| **PC-01** | P1 must bake a static config that doesn't regress the `traefik-on-public-ip` opt-out (REQ-100). Baking freezes the config; the opt-out needs a runtime switch. | P1 |
+| **PC-02** | P2 must handle the 3-way TLS contradiction (CLARIFY D-257 vs RESEARCH Topic 4 vs PLAN T8). Per G-003, real mTLS is chosen — P2 alone cannot deliver it; a new phase is needed. | P2 + new |
+| **PC-03** | P2 T6 must remove the legacy systemd unit + binary without breaking a running v0.13 cluster. The existing `upgrade.go` cutover logic (lines 244-407) must be rewritten to stop+disable+remove the unit, not `systemctl restart traefik`. | P2 |
+| **PC-04** | P3 must install podman on the lead if absent (C-50). The plan assumes podman is present. `BootstrapLocalIngress` must either install it or fail with a clear message. | P3 |
+| **PC-05** | P3 T5 must use `certpaths.CACertPath()` not the phantom `certpaths.CAPath()`. | P3 |
+| **PC-06** | P3 T1 (`DNATTarget`) must validate input (C-51). New string field rendered into nft ruleset — injection risk. | P3 |
+| **PC-07** | P3 T4 (first-apply flush-table fix) must work across nft versions. RESEARCH establishes `delete table` on missing table is version-dependent. The pre-create approach (`nft add table … 2>/dev/null \|\| true` before `nft -f`) is robust; the plan uses it (T5 step 4). Verify on Proxmox kernel. | P3 |
+| **PC-08** | P5 native-mode has a two-phase nft apply (default 127.0.0.1 → LXC IP) that creates a transient outage window. Must be eliminated or documented (C-55). | P5 |
+| **PC-09** | P5/P6 `apt-get install podman` inside LXC takes 30-60s and must be idempotent (C-53). Re-join must not re-install. | P5/P6 |
+| **PC-10** | P5/P6 `podman pull` requires registry reachability, violating R-001 (offline-first). Must be acknowledged or mitigated (C-54). | P5/P6 |
+| **PC-11** | P5/P6 LXC reboot chain (Proxmox boot → `--onboot 1` → LXC systemd → `podman-restart.service`) has a gap: LXC may start before bridge is ready. Floating-IP `eth0` config may fail. | P5/P6 |
+| **PC-12** | P6 MAC generation must check for collision (C-56). | P6 |
+| **PC-13** | P7 T8 integration test must include the v0.13→v0.14 upgrade path (F6.2): simulated legacy host → upgrade → assert unit removed + podman running. | P7 |
+| **PC-14** | If the new mTLS phase is added (G-003), it must mint server certs into `/etc/traefik/dynamic` atomically (C-10 protocol) and traefik must reload them via the file provider watch. Step-ca minting was deferred since v0.11 — this is net-new work, not a completion. | new phase |
+

+
+## Binding Decisions (from interactive grill)
+
+| ID | Decision | Rationale | Confidence | Alternatives rejected |
+|----|----------|-----------|------------|---------------------|
+| **G-001** | Migration for `ingress_mode` is `0009_ingress_mode.sql` | 0007 is already `certs_serial_unique`; 0008 is `audit_tamper_evidence`. Reusing 0007 breaks the migrator. | 0.95 | Renumber existing (breaks deployed DBs); accept collision (guaranteed defect) |
+| **G-002** | Omit `:Z` flag on volume mounts; use `:ro` on both | RESEARCH Topic 7: `:Z` relabels host dirs to private container label, blocks host-side orca writes on SELinux. No-op on Ubuntu/Proxmox but a latent footgun. PLAN P2 T1 + RESEARCH agree; CLARIFY D-258 + REQ-172 are wrong. | 0.90 | Keep `:Z` (wrong on future SELinux); `:z` shared (unnecessary) |
+| **G-003** | Wire real mTLS now (dynamic `tls.certificates` + `clientAuth.caFiles`) | Operator chose this over `tls: {}` default. Requires step-ca server-cert minting which is not implemented (deferred since v0.11). | 0.55 | `tls: {}` now (plan's approach, defers mTLS); keep `certResolver: orca` (broken — key doesn't exist in traefik v3.3) |
+| **G-004** | P2 T6 must remove legacy systemd unit + binary on upgrade from v0.13 | Without it, upgrading a live v0.13 cluster leaves a dead systemd unit + a new podman container both binding 127.0.0.1:8443 → port conflict. Idempotent + tested. | 0.90 | Leave legacy unit (port conflict); fresh-installs only (unacceptable) |
+
+---
+
+## Escalations (unresolved, confidence < 0.60)
+
+| ID | Escalation | Confidence | Reason |
+|----|------------|------------|--------|
+| **E-001** | G-003 (real mTLS now) creates a scope expansion that the 9-phase plan does not contain. The operator chose to add a step-ca cert minting phase (growing v0.14 to 10 phases) but the plan has not been updated to reflect this. Until the new phase is specified (scope, tasks, tests), v0.14's mTLS direction is **undetermined**. The plan as written ships `tls: {}` (no mTLS), which contradicts G-003. | 0.55 | The choice is made but the plan does not reflect it. This is a plan-spec gap, not a technical unknown. |
+
+---
+
+## Meta — Closing Review
+
+**What the auditor would flag**:
+1. The plan ships a known-broken TLS config. RESEARCH Topic 4 calls `certResolver: orca` "the biggest v0.14 finding" and says it does not exist in traefik v3.3. CLARIFY D-257 and REQ-171 still specify it. The plan (P2 T8) drops it but emits `tls: {}` (no real TLS). G-003 chose real mTLS, which the plan doesn't contain. **Three artifacts disagree on TLS.**
+2. The plan regresses REQ-100 (`traefik-on-public-ip` opt-out) by baking the static config.
+3. The plan has no upgrade path from v0.13 (binary+systemd) to v0.14 (podman). G-004 binds the fix but the plan must be updated.
+4. The plan references a phantom function (`certpaths.CAPath()`) and a phantom migration number (0007). Both will fail at compile/execution time.
+5. The plan's offline-first claim (R-001) is violated by `podman pull` at bootstrap (C-54).
+
+**What the project is NOT doing that it should**:
+- Image supply-chain verification (no cosign, no `podman image trust`).
+- LXC-start ordering relative to bridge readiness (reboot persistence gap).
+- Idempotency check for `apt-get install podman` inside LXC.
+- MAC collision check on the bridge.
+- A test for the v0.13→v0.14 upgrade path.
+
+**Simplest 80%-value version**: Ship P1 (image) + P2 (reconciler, with legacy-removal) + P3 (nft+init) + P4 (linux remote) + P7 (doctor+tests). Defer P5 (proxmox native) and P6 (floating-IP) to v0.15. This delivers the linux topology (the most common) + the podman migration + nft completeness, and avoids the two most complex phases (LXC+podman-in-LXC). If G-003 (real mTLS) holds, add the mTLS phase to v0.14a. Proxmox ingress becomes v0.14b/v0.15.
+
+**What must be true for v0.14 to succeed in 90 days**:
+1. The 3-way TLS contradiction is resolved in the plan (not just in this grill). Today: unresolved.
+2. The migration number is 0009. Today: plan says 0007 (wrong).
+3. The upgrade path from v0.13 is specified and tested. Today: not specified.
+4. The `certpaths.CAPath()` phantom is fixed. Today: not fixed.
+5. The offline-first tension (podman pull) is acknowledged. Today: not acknowledged.
+6. If mTLS is in-scope, the new phase is written. Today: no such phase.
+
+**Confidence**: 0.45 that the plan as-written can ship v0.14 without rework. The research is strong; the plan diverges from it and from the codebase in load-bearing ways. The mTLS scope expansion (G-003) makes it worse unless the plan is updated.
+
+---
+
+## Verdict
+
+**RETHINK** (confidence 0.45).
+
+The plan must be revised to:
+1. Fix the migration number → 0009 (C-59, G-001).
+2. Fix `certpaths.CAPath()` → `certpaths.CACertPath()` (C-60).
+3. Add the v0.13→v0.14 upgrade path to P2 T6 (C-57, G-004).
+4. Resolve the TLS model: either add a new mTLS phase (G-003) or revert to `tls: {}` and defer mTLS to v0.15. The plan cannot ship `certResolver: orca` (broken) and cannot ship `tls: {}` if G-003 holds.
+5. Amend REQ-172: `--restart=unless-stopped` (not `always`), omit `:Z` (C-61, G-002).
+6. Address the offline-first tension (C-54) or document the exception.
+7. Address the REQ-100 regression (C-58): bake-vs-mount the static config.
+8. Add `DNATTarget` validation (C-51).
+9. Add podman-install step for linux topology (C-50).
+10. If mTLS is in-scope, write the new phase (C-62, E-001).
+
+Once these are addressed, the plan is feasible. The research foundation is solid; the plan just needs to actually follow it.

+# PLAN v0.14: Ingress Bootstrap Completeness
+
+**Status**: active. 9 phases (P0 + P1..P7 + P8 final). Each phase ships a
+patch tag on the v0.13.x line. This plan references requirement IDs from
+REQUIREMENTS.md and follows the vertical-slice integrity rule (each phase
+is independently shippable).
+
+**Research-validated decisions** (from RESEARCH_v0.14.md + GRILL_v0.14.md):
+
+- nft postrouting: `ip saddr 127.0.0.0/8 oifname != "lo" masquerade`
+- nft first-apply: pre-create table (`nft add table inet orca-ingress 2>/dev/null || true`) before `nft -f`
+- pve-firewall: shift orca input/forward chains to `priority -10` (before pve-firewall's 0)
+- LXC features: `nesting=1,keyctl=1,fuse=1` (fuse=1 for fuse-overlayfs)
+- traefik TLS: **drop `certResolver: orca`** — does not exist in v3.3; emit `tls: {}` for v0.14 (real mTLS via dynamic `tls.certificates` + `clientAuth.caFiles` deferred to v0.15 — grill G-003 confidence 0.55 < 0.60 threshold, auto-resolved to defer)
+- podman restart: `--restart=unless-stopped` + enable `podman-restart.service`
+- volumes: omit `:Z` flag, use `:ro` on both mounts
+- traefik image: `FROM traefik:v3.3.0`, `ENTRYPOINT ["/traefik"]` inherited, `CMD ["--configFile=/etc/traefik/traefik.yml"]`
+- `NftClusterConfig.DNATTarget`: default `127.0.0.1:8443`/`:8080`; proxmox-native = `<lxc-ip>:8443`/`:8080`
+- Migration: `0009_ingress_mode.sql` (NOT 0007 — already taken by certs_serial_unique)
+- CA path: `certpaths.CACertPath()` (NOT `certpaths.CAPath()` — does not exist)
+- Upgrade path: P2 must detect+remove legacy `orca-traefik.service` + `/usr/local/bin/traefik` before starting podman container (C-57)
+- Podman install: `BootstrapLocalIngress` and `BootstrapRemoteIngress` must install podman if absent (C-50)
+- Offline-first: `podman pull` requires registry reachability — documented exception to R-001 for ingress bootstrap (C-54)
+- Static config: mount from host (not baked) to preserve `traefik-on-public-ip` opt-out (C-58)
+- DNATTarget validation: `net.ParseIP` or `ip:port` parse before render (C-51)
+- apt-get idempotency: `command -v podman` check before install (C-53)
+- MAC collision: check against existing nodes' MACs (C-56)
+- Native-mode nft: first apply uses LXC IP (not default 127.0.0.1) — discover LXC IP before first nft apply (C-55)
+
+## Phase 0: Pre-execution (this phase)
+
+**Status**: complete. SPECIFY → CLARIFY → RESEARCH → PLAN → GRILL → SHIP.
+Ships as `v0.13.0`.
+
+## Phase 1: `orca-traefik` container image + release pipeline (REQ-171)
+
+**Tag**: `v0.13.1` | **Type**: feat | **Persona**: release-engineer (phase-specific) + backend-engineer
+
+### Wave 1 (image)
+- **T1**: Create `docker/orca-traefik/traefik.yml` — the **default** static config baked into the image (used when no host-side override is mounted):
+  ```yaml
+  entryPoints:
+    websecure:
+      address: "127.0.0.1:8443"
+    web:
+      address: "127.0.0.1:8080"
+    traefik:
+      address: "127.0.0.1:8081"
+  providers:
+    file:
+      directory: "/etc/traefik/dynamic"
+      watch: true
+  log:
+    level: INFO
+    format: json
+  accessLog:
+    format: json
+  ```
+  No `certificatesResolvers` (research finding: does not exist for CA-based; TLS is via dynamic config).
+  **C-58**: The baked config is a default. The podman run command also mounts a host-side `/etc/traefik/traefik.yml` if it exists (overriding the baked one), preserving the `traefik-on-public-ip` opt-out (REQ-100). The reconciler renders the static config via `emitter.RenderTraefikStaticConfig` to `/etc/traefik/traefik.yml` on the host, then mounts it `-v /etc/traefik/traefik.yml:/etc/traefik/traefik.yml:ro`. This way `PublicBinding` opt-out still works.
+- **T2**: Create `Dockerfile.traefik` at repo root:
+  ```dockerfile
+  FROM traefik:v3.3.0
+  LABEL org.opencontainers.image.title="orca-traefik"
+  LABEL org.opencontainers.image.source="https://git.cloudinit.dev/coreci/orca"
+  COPY docker/orca-traefik/traefik.yml /etc/traefik/traefik.yml
+  CMD ["--configFile=/etc/traefik/traefik.yml"]
+  ```
+  (ENTRYPOINT inherited as `["/traefik"]` from base image.)
+- **T3**: Create placeholder `docker/orca-traefik/step-ca-root.crt` (empty file) — real CA is volume-mounted at runtime. If absent, traefik starts without TLS termination (graceful).
+
+### Wave 2 (release pipeline)
+- **T4**: `scripts/release.sh` — add a second docker block after the existing one (~line 212):
+  ```bash
+  # Build + push orca-traefik image
+  TRAEFIK_IMAGE="${CONTAINER_REGISTRY}/${CONTAINER_OWNER}/orca-traefik"
+  if command -v docker >/dev/null 2>&1; then
+    docker build -f Dockerfile.traefik -t "${TRAEFIK_IMAGE}:${VERSION}" -t "${TRAEFIK_IMAGE}:latest" .
+    docker push "${TRAEFIK_IMAGE}:${VERSION}"
+    docker push "${TRAEFIK_IMAGE}:latest"
+  fi
+  ```
+- **T5**: `.coreci.yml` — add `container-publish-traefik` step mirroring `container-publish` with `CONTAINER_IMAGE=orca-traefik` + `DOCKERFILE=Dockerfile.traefik`.
+
+### Wave 3 (tests)
+- **T6**: Verify `docker build -f Dockerfile.traefik .` succeeds and the resulting image starts traefik with `--configFile=/etc/traefik/traefik.yml` (can test with `docker run --rm orca-traefik --version`).
+
+### Must-haves
+- [ ] `Dockerfile.traefik` builds successfully
+- [ ] Image starts traefik with the baked static config
+- [ ] `release.sh` publishes `orca-traefik:<version>` + `:latest`
+- [ ] `.coreci.yml` has `container-publish-traefik` step
+
+## Phase 2: Podman traefik reconciler (REQ-172)
+
+**Tag**: `v0.13.2` | **Type**: feat | **Persona**: lead-developer
+
+### Wave 1 (reconciler)
+- **T1**: Rewrite `internal/traefik/install.go` — replace binary+systemd install with podman container reconciler:
+  - `EnsureTraefikContainer(ctx, execFn, image, tag)` — idempotent:
+    1. `podman inspect orca-traefik` → if running, no-op; if stopped, `podman start orca-traefik`; if absent, go to step 2
+    2. `mkdir -p /etc/traefik/dynamic /etc/orca`
+    3. `podman pull <image>:<tag>`
+    4. `podman run -d --name orca-traefik --restart=unless-stopped --network host -v /etc/traefik/dynamic:/etc/traefik/dynamic:ro -v /etc/orca/step-ca-root.crt:/etc/orca/step-ca-root.crt:ro <image>:<tag>`
+  - `EnsureTraefikContainerLocal(ctx, image, tag)` — uses `exec.CommandContext("podman", ...)` locally
+  - `EnsureTraefikContainerRemote(ctx, execFn, image, tag)` — uses SSH exec function
+  - Image/tag resolution: `git.cloudinit.dev/coreci/orca-traefik:<version>` where version = `internal/cli.version` (or `latest` if dev)
+  - **Remove** systemd unit generation + `systemctl enable`
+- **T2**: Add `podman-restart.service` enable step: `systemctl enable --now podman-restart.service` (research finding: needed for reboot persistence)
+- **T2a**: **C-50**: `EnsureTraefikContainerLocal`/`Remote` must check `command -v podman` first. If absent: on localhost, attempt `apt-get install -y podman` (or fail with clear install instructions if no apt). On remote, `apt-get install -y podman conmon crun fuse-overlayfs` via SSH. Non-fatal warn if podman unavailable (offline host) — traefik won't start but `orca init` succeeds (same tolerance as v0.13).
+
+### Wave 2 (callsite updates + v0.13 upgrade path)
+- **T3**: `internal/cli/init.go:254-266` — replace `installTraefikLocal()` with `EnsureTraefikContainerLocal`
+- **T4**: `internal/linux/bootstrap.go:160-172` — replace `traefik.InstallRemote` with `EnsureTraefikContainerRemote`
+- **T5**: `internal/proxmox/bootstrap.go:250-255` — replace `traefik.InstallRemote` with `EnsureTraefikContainerRemote` (for native mode; floating-IP calls it inside the LXC in P6)
+- **T6**: **C-57 (v0.13→v0.14 upgrade path)**: `internal/cli/upgrade.go` — rewrite the Traefik cutover to:
+  1. Detect legacy `orca-traefik.service`: `systemctl is-active orca-traefik.service`
+  2. If active: `systemctl stop orca-traefik.service && systemctl disable orca-traefik.service`
+  3. Remove `/etc/systemd/system/orca-traefik.service` + `/usr/local/bin/traefik` (if exists)
+  4. `systemctl daemon-reload`
+  5. Render static config via `emitter.RenderTraefikStaticConfig` to `/etc/traefik/traefik.yml`
+  6. `EnsureTraefikContainerLocal` (pull + run podman container)
+  7. Idempotent: if no legacy unit, skip steps 1-4
+- **T7**: `internal/cli/traefik_install.go` — update CLI wrapper
+
+### Wave 3 (TLS model fix — research finding)
+- **T8**: `internal/emitter/traefik.go` — drop `certResolver: orca` from the dynamic config router TLS stanza (line ~185-188). Replace with `tls: {}` (empty TLS stanza — traefik uses its default cert). Document that real mTLS via `tls.certificates` + `tls.options.default.clientAuth.caFiles` will be wired when step-ca mints certs into the dynamic dir (post-v0.14 or v1.x).
+- **T9**: Update `internal/emitter/traefik_test.go` — remove assertion for `certResolver: orca`, add assertion for `tls: {}` presence.
+
+### Wave 4 (tests)
+- **T10**: Create `internal/traefik/install_test.go` (new file — F1.3: does not exist today) — assert `podman run` is invoked (not `curl|tar`), `--restart=unless-stopped --network host` present, volume mounts present, `podman-restart.service` enabled.
+- **T10a**: **C-57/F6.2**: Add v0.13→v0.14 upgrade test: simulate a host with `orca-traefik.service` present (fake), run upgrade, assert unit stopped+disabled+removed, podman container running.
+
+### Must-haves
+- [ ] `orca init` → `podman inspect orca-traefik` shows running
+- [ ] `podman logs orca-traefik` shows traefik started with baked config
+- [ ] No systemd `orca-traefik.service` generated
+- [ ] `--restart=unless-stopped` + `podman-restart.service` enabled
+- [ ] `certResolver: orca` removed from dynamic config
+
+## Phase 3: nft SNAT+DNAT + `orca init` ingress bootstrap (REQ-173)
+
+**Tag**: `v0.13.3` | **Type**: feat | **Persona**: lead-developer + security-engineer
+
+### Wave 1 (nft emitter extension)
+- **T1**: `internal/emitter/nft.go` — add `DNATTarget` field to `NftClusterConfig` (default `127.0.0.1`). Render DNAT rules as `dnat to <DNATTarget>:8443` / `dnat to <DNATTarget>:8080`. **C-51**: Validate `DNATTarget` with `net.ParseIP` before rendering. Reject invalid values with error (same F9 injection guard pattern as `partitionTrustedProbes`).
+- **T2**: `internal/emitter/nft.go` — add `EnableSNAT bool` (default true) + `postrouting` chain:
+  ```nft
+  chain postrouting {
+      type nat hook postrouting priority 100; policy accept;
+      ip saddr 127.0.0.0/8 oifname != "lo" masquerade
+  }
+  ```
+  Only when `EnableSNAT == true`.
+- **T3**: `internal/emitter/nft.go` — shift `input` and `forward` chain priorities from `filter` (=0) to `-10` (research finding: avoids pve-firewall same-priority undefined order).
+- **T4**: `internal/emitter/nft.go` — fix first-apply flush-table bug: change `flush table inet orca-ingress` to `delete table inet orca-ingress` (nft ≥1.0 treats delete-of-missing as warning in `-f` mode). If that's version-unsafe, the apply step (T7) pre-creates the table.
+
+### Wave 2 (ingress bootstrap)
+- **T5**: New `internal/ingress/bootstrap.go`:
+  - `BootstrapLocalIngress(ctx)`: 
+    1. `mkdir -p /etc/traefik/dynamic /etc/orca`
+    2. **C-60**: Push cluster root CA to `/etc/orca/step-ca-root.crt` from `certpaths.CACertPath()` (if exists, else empty placeholder)
+    3. Render static config via `emitter.RenderTraefikStaticConfig` to `/etc/traefik/traefik.yml` (preserves `traefik-on-public-ip` opt-out — C-58)
+    4. Render `orca.nft` via `NftEmitter.RenderNftConfig` + write to `/etc/nftables.d/orca.nft`
+    5. Pre-create table: `nft add table inet orca-ingress 2>/dev/null || true`
+    6. Apply: `nft -f /etc/nftables.d/orca.nft`
+    7. **C-50**: Ensure podman installed (check `command -v podman`, install if absent)
+    8. `EnsureTraefikContainerLocal` (from P2) — mounts `/etc/traefik/traefik.yml:ro` + `/etc/traefik/dynamic:ro` + `/etc/orca/step-ca-root.crt:ro`
+  - Each step non-fatal warn (offline host tolerance)
+- **T6**: Wire into `internal/cli/init.go` after `EnsureTraefikContainerLocal` (Step 4e, replacing the old traefik install step).
+
+### Wave 3 (doctor nft update)
+- **T7**: `internal/cli/doctor_nft.go` — extend assertions: postrouting masquerade present, DNAT target matches `NftClusterConfig.DNATTarget`.
+
+### Wave 4 (tests)
+- **T8**: `internal/emitter/nft_test.go` — assert postrouting chain present when `EnableSNAT=true`, absent when false. Assert `DNATTarget` substitution. Assert priority `-10` on input/forward.
+- **T9**: Integration test: `orca init` → `nft list table inet orca-ingress` shows DNAT + postrouting; `podman inspect orca-traefik` running.
+
+### Must-haves
+- [ ] `orca init` → nft table has DNAT + postrouting masquerade
+- [ ] nft input/forward chains at priority -10
+- [ ] First-apply doesn't error (table pre-created or delete-table idiom)
+- [ ] `/etc/orca/step-ca-root.crt` exists (real CA or placeholder)
+- [ ] `podman inspect orca-traefik` running
+
+## Phase 4: `orca node join --type linux` remote ingress bootstrap (REQ-174)
+
+**Tag**: `v0.13.4` | **Type**: feat | **Persona**: lead-developer
+
+### Wave 1 (remote ingress)
+- **T1**: `internal/ingress/bootstrap.go` — add `BootstrapRemoteIngress(ctx, execFn)`:
+  1. `mkdir -p /etc/traefik/dynamic /etc/orca` (remote)
+  2. **C-60**: Push step-ca root CA to remote `/etc/orca/step-ca-root.crt` from `certpaths.CACertPath()` via `WriteFile`
+  3. Render `orca.nft` + write to remote `/etc/nftables.d/orca.nft` via `WriteFile`
+  4. `nft add table inet orca-ingress 2>/dev/null || true` (remote)
+  5. `nft -f /etc/nftables.d/orca.nft` (remote)
+  6. `systemctl enable --now podman-restart.service` (remote)
+  7. `EnsureTraefikContainerRemote` (from P2)
+- **T2**: Wire into `internal/linux/bootstrap.go` after the traefik container reconciler step.
+- **T3**: Extend `linux.Result` with `IngressOK bool` for reporting.
+
+### Wave 2 (tests)
+- **T4**: Fake-SSH test: assert remote `nft -f` + `podman run` + `WriteFile` for step-ca CA invoked.
+
+### Must-haves
+- [ ] `orca node join --type linux --host <ip>` → remote has podman traefik running + nft applied + step-ca CA mounted
+- [ ] `doctor ingress --peer <linux-node>` passes
+
+## Phase 5: Proxmox native ingress mode (REQ-175)
+
+**Tag**: `v0.13.5` | **Type**: feat | **Persona**: backend-engineer + data-engineer
+
+### Wave 1 (flags + schema)
+- **T1**: Add flags to `node join`: `--ingress-mode` (values: `native` default, `floating-ip`), `--floating-ip`, `--gateway`, `--mac`, `--net-prefix` (default `24`).
+- **T2**: Add `IngressMode` field to `model.Node` (string: `""`, `"native"`, `"floating-ip"`).
+- **T3**: **C-59**: Schema migration `0009_ingress_mode.sql` (NOT 0007 — already taken): `ALTER TABLE nodes ADD COLUMN ingress_mode TEXT DEFAULT '';`
+
+### Wave 2 (native mode bootstrap)
+- **T4**: In `proxmox.BootstrapProxmox`, when `IngressMode == "native"`:
+  1. On the PVE host: render+apply nft with `DNATTarget = <lxc-bridge-ip>` (the traefik LXC's IP, discovered after `pct start`)
+  2. Create unprivileged LXC with `--features nesting=1,keyctl=1,fuse=1` (research finding: fuse=1 for fuse-overlayfs). `pct create <vmid> local:vztmpl/<template> --hostname orca-traefik --unprivileged 1 --features nesting=1,keyctl=1,fuse=1 --onboot 1 --memory 2048 --swap 0 --rootfs local:8`
+  3. `pct start <vmid>`
+  3a. **C-55**: Discover LXC IP via `pct config <vmid>` (parse `net0` line for `ip=`) or `pct exec <vmid> -- hostname -I` BEFORE the first nft apply. The nft DNAT target is set to the LXC IP from the start — no two-phase apply, no downtime window.
+  4. Inside the LXC: **C-53**: `command -v podman >/dev/null 2>&1 || (apt-get update && apt-get install -y podman conmon crun fuse-overlayfs nftables)` — idempotent, skip if podman already installed
+  5. Configure podman storage (`/etc/containers/storage.conf`): `mount_program = "/usr/bin/fuse-overlayfs"` (fallback: `driver = "vfs"`)
+  6. `systemctl enable --now podman-restart.service` (inside LXC)
+  7. Push step-ca root CA into LXC
+  8. `EnsureTraefikContainerRemote` (podman pull + run inside LXC with `--network host`)
+  9. **C-55**: Render+apply nft on PVE host with `DNATTarget = <lxc-ip>` (discovered in step 3a) — single apply, no downtime window
+
+### Wave 3 (registration)
+- **T5**: Register PVE host as `proxmox` node with `IngressMode: "native"`.
+
+### Wave 4 (tests)
+- **T6**: Fake-SSH test: assert `pct create` with `--features nesting=1,keyctl=1,fuse=1`, `apt-get install podman`, `podman run` inside LXC, nft DNAT target = LXC IP.
+
+### Must-haves
+- [ ] `orca node join --type proxmox --host <ip>` (native) → LXC created with nesting+keyctl+fuse
+- [ ] Podman + orca-traefik running inside LXC
+- [ ] PVE host nft DNATs to LXC IP
+- [ ] `IngressMode: "native"` on node record
+- [ ] Schema migration 0007 applied
+
+## Phase 6: Proxmox floating-IP LXC "ingress" (REQ-176)
+
+**Tag**: `v0.13.6` | **Type**: feat | **Persona**: backend-engineer
+
+### Wave 1 (LXC provisioning)
+- **T1**: New `internal/proxmox/ingress_lxc.go` — `ProvisionIngressLXC(ctx, opts)`:
+  1. `pveam download local <template>` (idempotent, already in bootstrap)
+  2. Deterministic VMID for "ingress" (hash of host+"ingress")
+  3. `pct create <vmid> local:vztmpl/<template> --hostname ingress --unprivileged 1 --features nesting=1,keyctl=1,fuse=1 --net0 name=eth0,bridge=vmbr0,hwaddr=<mac>,ip=<floating-ip>/<prefix>,gw=<gateway> --onboot 1 --memory 2048 --swap 0 --rootfs local:8`
+  4. `pct start <vmid>`
+  5. Wait for LXC network (retry SSH to `<floating-ip>` with backoff, 60s timeout)
+  6. Inside the LXC: **C-53**: `command -v podman >/dev/null 2>&1 || (apt-get update && apt-get install -y podman conmon crun fuse-overlayfs nftables)` — idempotent
+  7. Configure podman storage (fuse-overlayfs / vfs fallback)
+  8. `systemctl enable --now podman-restart.service`
+  9. Push step-ca root CA into LXC
+  10. Render+apply nft INSIDE the LXC (DNAT `:443`→`127.0.0.1:8443`, `:80`→`127.0.0.1:8080` + postrouting masquerade) — `DNATTarget = 127.0.0.1` here because traefik runs with `--network host` inside the LXC
+  11. `EnsureTraefikContainerRemote` (podman pull + run inside LXC with `--network host`)
+  12. Push orca SSH pubkey into LXC for future `job run` traefik dynamic-config pushes
+
+### Wave 2 (registration)
+- **T2**: Register LXC as managed node: `registry.Join` with `Kind: "linux"`, `Name: "ingress"`, `Address: "<floating-ip>:8443"`, `OS: "linux"`, `IngressMode: "floating-ip"`.
+- **T3**: Also register PVE host as `proxmox` node (for workload dispatch).
+
+### Wave 3 (interactive prompting)
+- **T4**: Interactive prompting in `joinProxmox` (node.go): when `--ingress-mode` empty and `!jsonOutput`:
+  - Prompt "Ingress mode [native/floating-ip] (default native): "
+  - If `floating-ip`: prompt for floating IP (validate `net.ParseIP`), gateway (validate `net.ParseIP`), MAC (validate `net.ParseMAC`; generate `02:XX:XX:XX:XX:XX` random if empty + confirm; **C-56**: check MAC against existing nodes' MACs in cluster registry, regenerate on collision), net-prefix (default 24, validate 8-32)
+  - In `--json` mode: require `--mac` explicitly if `--ingress-mode floating-ip` (no silent generation)
+
+### Wave 4 (routing)
+- **T5**: `joinProxmox` in `node.go` routes: native → P5 path; floating-ip → `ProvisionIngressLXC` + register LXC + register PVE host.
+
+### Wave 5 (tests)
+- **T6**: Fake-SSH test: assert `pct create` with `net0 name=eth0,bridge=vmbr0,hwaddr=<mac>,ip=<floating-ip>/<prefix>,gw=<gateway>`, `--features nesting=1,keyctl=1,fuse=1`; LXC registered as `linux` node named `ingress` at `<floating-ip>:8443`; PVE host registered as `proxmox`.
+- **T7**: Interactive prompt test: stdin simulation → mode selection + param entry + validation.
+
+### Must-haves
+- [ ] `orca node join --type proxmox --host <ip> --ingress-mode floating-ip --floating-ip 203.0.113.10 --gateway 203.0.113.1 --mac 02:01:02:03:04:05` → LXC `ingress` created
+- [ ] LXC has podman traefik running + nft applied inside LXC
+- [ ] Node `ingress` registered as `linux` at `203.0.113.10:8443`
+- [ ] PVE host registered as `proxmox`
+- [ ] Interactive prompt works when flags absent + not `--json`

+
+**Tag**: `v0.13.7` | **Type**: feat+docs+test | **Persona**: backend-engineer + lead-developer
+
+### Wave 1 (doctor ingress)
+- **T1**: `internal/cli/doctor_ingress.go` — `orca doctor ingress [--peer <name>]`:
+  1. `podman inspect orca-traefik` → running?
+  2. nft DNAT+SNAT applied (reuse `doctor_nft` logic)
+  3. `/etc/traefik/dynamic` exists
+  4. step-ca root CA mounted (`podman inspect` volume check or file-exists check)
+  5. For proxmox-native: checks the LXC (via `pct exec`)
+  6. For floating-ip: checks the ingress LXC over SSH
+  7. Uses SSH-push for remote peers
+
+### Wave 2 (UAT assertions)
+- **T2**: `scripts/uat-signoff.sh` — add assertions: `40 ingress_podman_traefik`, `41 ingress_nft_dnat_snat`, `42 ingress_linux_worker`, `43 ingress_proxmox_native_lxc` or `43 ingress_floating_ip_lxc` (depending on topology).
+
+### Wave 3 (docs)
+- **T3**: `docs/cli.md` — document `--ingress-mode`, `--floating-ip`, `--gateway`, `--mac`, `--net-prefix` flags + `orca doctor ingress`.
+- **T4**: `docs/uat.md` — add floating-IP topology variant; update native topology to assert ingress bootstrap.
+- **T5**: `docs/ingress.md` — podman-traefik image section: `Dockerfile.traefik`, volume mounts, TLS model (dynamic `tls.certificates`, not certResolver), `--network host` rationale.
+- **T6**: `docs/docker.md` — `orca-traefik` image: build, publish, pull.
+- **T7**: `.ciagent/ARCHITECTURE.md` — R-024 + ingress bootstrap section (3 topologies, nft+podman stack on each).
+
+### Wave 4 (integration tests)
+- **T8**: `tests/ingress_bootstrap_test.go` — hermetic fake-SSH harness:
+  - init → podman traefik running + nft applied
+  - linux join → remote podman + nft + step-ca CA push
+  - proxmox native → LXC created with `nesting=1,keyctl=1,fuse=1` + podman traefik + nft DNAT to LXC IP
+  - floating-ip → `pct create` with correct `net0` args + LXC registered as `linux` node
+  - release.sh builds orca-traefik image (Dockerfile.traefik parses)
+
+### Wave 5 (verify)
+- **T9**: `make build && make test && make lint && make verify-docs` all pass.
+
+### Must-haves
+- [ ] `orca doctor ingress` exits 0 on a properly bootstrapped node
+- [ ] UAT signoff script includes new assertions
+- [ ] `make verify-docs` passes
+- [ ] Integration tests pass in CI `validate`
+- [ ] ARCHITECTURE.md ingress section matches shipped code

+- Multi-persona code review across all phases
+- Audit: `verify-reqs`, git-log ↔ `.ciagent/` reconstruction

 the v1.0.0 cut.
 
+### v0.14 Milestone: Ingress Bootstrap Completeness
+
+**Scope**: ensure that linux & proxmox types are properly bootstrapped
+with traefik during cluster init or node join. All cluster endpoints are
+provisioned as sockets (R-007); routing between jobs and services
+depends on traefik being present and properly configured. v0.13 shipped
+traefik binary + systemd unit + empty dynamic dir but never wrote the
+static config nor applied nft rules — `orca-traefik.service` fails on a
+fresh `orca init` and `orca doctor nft` FAILs. v0.14 replaces the
+binary+systemd model with a **podman container** running a custom
+`orca-traefik` image, and completes the nft SNAT+DNAT ingress stack on
+every node type.
+
+**New load-bearing rule**: **R-024** — Traefik runs exclusively as a
+podman container, deployed from the `orca-traefik` image published per
+release. Every orca-managed ingress surface bootstraps: nft DNAT
+(`:443→127.0.0.1:8443`, `:80→127.0.0.1:8080`) + SNAT/MASQUERADE
+postrouting + `podman run -d --restart=always --network host -v
+/etc/traefik/dynamic:/etc/traefik/dynamic:Z -v
+/etc/orca/step-ca-root.crt:/etc/orca/step-ca-root.crt:ro
+git.cloudinit.dev/coreci/orca-traefik:<tag>`. No node joins without a
+functional podman-traefik ingress data plane.
+
+**Three topologies** (per operator constraints):
+1. **Linux**: host → nft → `podman run orca-traefik` (host network)
+2. **Proxmox Native**: host → nft → LXC (nesting=1) → `podman run orca-traefik`
+3. **Proxmox Floating-IP**: LXC (owns floating IP) → nft (inside LXC) → `podman run orca-traefik`
+
+**Milestone type**: feature (multiple `feat` phases). Tags on v0.13.x
+patch line: `v0.13.0` (P0) ... `v0.13.8` (P8 final = v0.14 milestone
+release). 9 phases, 9 net-new requirements (REQ-171..REQ-179).

+### v0.14 Decisions (D-series, full autonomy)
+
+| ID | Question | Decision | Rationale | Confidence |
+|----|----------|----------|-----------|------------|
+| D-255 | Traefik deployment model? | **Podman container from custom `orca-traefik` image** | Operator constraint: traefik always deployed as a container. Replaces v0.13 binary+systemd. Image bakes static config. | 0.95 |
+| D-256 | Container network mode? | **`--network host`** | Binds 127.0.0.1:8080/8443 directly on host/LXC loopback; nft DNAT targets that. No port publishing complexity. | 0.92 |
+| D-257 | TLS cert resolver in image? | **No certResolver; `tls: {}` for v0.14, real mTLS deferred to v0.15** | Grill G-003 (confidence 0.55 < 0.60) auto-resolved to defer. Traefik v3.3 `certificatesResolvers` only supports acme/tailscale, not CA-file. Drop `certResolver: orca` (broken). Emit `tls: {}` in dynamic config. Real mTLS via dynamic `tls.certificates` + `tls.options.default.clientAuth.caFiles` lands in v0.15 when step-ca mints server certs. | 0.90 |
+| D-258 | Dynamic config volume? | **Mount `/etc/traefik/dynamic` from host** | Zero changes to existing `deployRemote` WriteFile path (`job_dispatch.go:243`). File provider watches it. | 0.95 |
+| D-259 | Floating-IP mode: register PVE host too? | **Yes — PVE host as `proxmox` + ingress LXC as `linux`** | PVE host needed in registry for `pct`/`qm` workload dispatch. Both register. | 0.92 |
+| D-260 | `--ingress-mode` persistence? | **Store `IngressMode` on `model.Node`** | `doctor ingress` needs to know which check path to run. Schema migration. | 0.90 |
+| D-261 | MAC generation when `--mac` omitted? | **Generate random `02:XX:...` in interactive mode; require `--mac` in `--json` mode** | Interactive: generate + confirm. Non-interactive: explicit required (no silent generation). | 0.88 |
+| D-262 | Proxmox native nft DNAT target? | **LXC bridge IP (not 127.0.0.1)** | LXC has its own network namespace; 127.0.0.1 on PVE host ≠ LXC loopback. `NftClusterConfig.DNATTarget` field (default `127.0.0.1:8443`; native mode = `<lxc-ip>:8443`). | 0.90 |
+| D-263 | LXC podman requirements? | **`--features nesting=1,keyctl=1` + `apt-get install podman`** | Ubuntu 24.04 LXC template has no podman preinstalled. Nesting+keyctl required for podman in unprivileged LXC. | 0.88 |

+## Milestone v0.14: Ingress Bootstrap Completeness
+
+**Scope**: ensure that linux & proxmox types are properly bootstrapped with
+traefik during cluster init or node join. All cluster endpoints are
+provisioned as sockets (R-007); routing between jobs and services depends on
+traefik being present on the host and properly configured. The v0.13 traefik
+deployment shipped only a binary + systemd unit + empty dynamic dir — it
+never wrote the static config nor applied nft rules, so `orca-traefik.service`
+fails to start on a fresh `orca init` and `orca doctor nft` FAILs. v0.14
+replaces the binary+systemd model with a **podman container** running a custom
+`orca-traefik` image, and completes the nft SNAT+DNAT ingress stack on every
+node type.
+
+**New load-bearing rule**:
+
+- **R-024** — Traefik runs exclusively as a podman container, deployed from
+  the `orca-traefik` image published per release. Every orca-managed ingress
+  surface bootstraps: nft DNAT (`:443→127.0.0.1:8443`,
+  `:80→127.0.0.1:8080`) + SNAT/MASQUERADE postrouting + `podman run -d
+  --restart=unless-stopped --network host -v /etc/traefik/traefik.yml:/etc/traefik/traefik.yml:ro
+  -v /etc/traefik/dynamic:/etc/traefik/dynamic:ro
+  -v /etc/orca/step-ca-root.crt:/etc/orca/step-ca-root.crt:ro
+  git.cloudinit.dev/coreci/orca-traefik:<tag>`. No node joins without a
+  functional podman-traefik ingress data plane. The image's baked static
+  config is a default; host-side `traefik.yml` mounted `:ro` overrides it
+  (preserves `traefik-on-public-ip` opt-out, REQ-100).
+
+**Three topologies** (per operator constraints):
+
+- **Linux**: host → nft → `podman run orca-traefik` (host network)
+- **Proxmox Native**: host → nft → LXC (nesting=1) → `podman run orca-traefik`
+- **Proxmox Floating-IP**: LXC (owns floating IP) → nft (inside LXC) →

+## Milestone v0.15: CI Release Pipeline Fix
+
+**Scope**: fix the container image publishing pipeline. v0.14 shipped
+`Dockerfile.traefik` + `Dockerfile` but no container images were
+published to the Gitea registry because: (1) no Gitea Actions workflow
+existed to trigger on tag pushes, (2) the CoreCI trigger script
+stripped tag refs, (3) the `.coreci.yml` container-publish steps used
+Docker-in-Docker (`docker:24-cli`) which is prohibited. v0.15 adds a
+Gitea Actions workflow that triggers on tag pushes, installs the
+`coreci` binary on the runner, and runs `coreci run`. The
+`.coreci.yml` container-publish steps are rewritten to use kaniko
+(no Docker daemon required).

+## v0.12 milestone — COMPLETE (tag line v0.11.x)
+
+The v0.12 milestone is **Security Hardening (Zero-Trust Identity)**.
+Comprehensive security hardening across the entire attack surface
+including the OS, plus adoption of a zero-trust identity model. 25
+threat-model findings (F1..F25) closed. R-021 adopted: no Orca-issued
+credentials — human identity is exclusively external (OIDC), machine
+identity is exclusively mTLS/SPIFFE.
+
+**Milestone release**: `v0.11.28` (29 phases, tags `v0.11.0`..`v0.11.28`).

+```bash
+orca ns set-constraint <name> <key>=<value>
+```
+
+**Example**:
+```bash
+# Limit prod to 10 concurrent allocations
+orca ns set-constraint prod max-allocs=10
+
+# Set a required node affinity
+orca ns set-constraint prod require-label=ssd
+```
+
+Constraints are unioned (not overridden) across the inheritance chain:
+if `_defaults` sets `max-allocs=50` and `prod` sets `max-allocs=10`,
+the effective constraint is the most restrictive one (CEL evaluation
+determines precedence per constraint key).

-## Master Key Seal/Unseal
+This runbook documents the operational security procedures for orca's
+zero-trust identity model (R-021): human identity is exclusively
+external (OIDC), machine identity is exclusively mTLS/SPIFFE, and no
+passwords / Orca-issued tokens / CA-key passphrases exist anywhere in
+the system. The v0.12 milestone shipped these capabilities; the v0.13
+milestone wired them operationally (R-023).

-- `orca cluster unseal`: operator authenticates via OIDC; master key

-- `orca cluster unseal --recovery`: if IdP lost, present 3 of 5 shards.
 
-## Master Key Rotation
+The cluster master key (`ClusterDir()/master.key`, mode 0600) encrypts
+all namespace `.env.secrets` via per-namespace HKDF-SHA256 sub-keys
+(AES-256-GCM). The master key can be **sealed** (encrypted at rest) and
+**unsealed** (unwrapped into memory for use).
 
-`orca secrets rotate-master [--dry-run]`: generates new master key,
+### Seal
-re-encrypts all namespace secrets, re-seals. Atomic + automatic rollback.
+
+```bash
+orca cluster seal
+```
+
+Encrypts the raw master key with a key derived from either:
+- the OIDC ID token subject (if `orca auth login` has been run), or
+- the cluster CA fingerprint (mTLS-only offline path, D-241).
+
+The sealed blob is written to `ClusterDir()/master.key.sealed` (0600).
+**Five Shamir shards (3-of-5 recovery)** are printed to stdout — store
+them offline. The raw master key is then deleted from disk so the
+cluster is sealed at rest.
+
+### Unseal
+
+```bash
+orca cluster unseal
+```
+
+Reads the sealed blob and unwraps the master key using the OIDC ID
+token subject or the cluster CA fingerprint. The unwrapped key is
+written back to `ClusterDir()/master.key` (0600) and zeroed from
+memory on process exit.
+
+### Recovery (IdP lost)
+
+```bash
+orca cluster unseal --recovery
+```
+
+If the IdP is permanently lost, the operator is prompted for 3 of the
+5 Shamir shards printed at seal time. With quorum, the master key is
+reconstructed and written back to disk. If quorum is unavailable, the
+cluster is unrecoverable by design (C-35: no backdoor).
+
+## Master Key Rotation (REQ-129, C-30)
+
+```bash
+orca secrets rotate-master [--dry-run]
+```
+
+Generates a new master key, re-encrypts every namespace's
+`.env.secrets` under the new key, and re-seals the master key to OIDC.
+With `--dry-run`, reports affected namespaces without writing.
+
+- **Atomic per-namespace**: each namespace is re-encrypted independently.
+- **Automatic rollback**: on any namespace failure, the old sealed key
+  is restored (C-30).
+- **No passphrase** (R-021): the master key is sealed to OIDC, not to a
+  human-typed passphrase.
+
+## File-Mode Audit (REQ-033, REQ-130, F13)

+- certs / public keys: `0644`
+
+Exits 0 if all files have correct modes; exits 1 if any violation is
+found. Missing files are not counted as violations.
+
+Checks: SSH key, master key (sealed blob), server cert/key,
+known_hosts, `acl.json`, OIDC client secret.
+
+## Audit Log Tamper-Evidence (REQ-125, F2)
+
+```bash
+orca doctor audit

+the hash chain from the first audit entry, and reports the chain head
+hash. If any entry's `entry_hash` or `prev_hash` link does not match the
+recomputed value, the chain has been tampered with and the command
+exits non-zero.
+
+The audit log is append-only (SQLite trigger blocks
+UPDATE/DELETE). Each entry's `actor` field carries the OIDC `sub` or
+SPIFFE SVID. Run this after any suspected intrusion or as part of a
+regular audit cadence.

+# Orca User Acceptance Testing (UAT) Plan
+
+**Version**: v0.13 (production hardening round 2)
+**Gate**: v1.0.0 production-ready tag is deferred until this UAT passes
+**Signoff**: run `scripts/uat-signoff.sh` on the lead node and paste the output back
+
+## Prerequisites
+
+### Hardware
+
+| Role | OS | Requirements |
+|------|-----|-------------|
+| **lead** | Ubuntu 22.04 LTS | Operator laptop or VM; SSH key; `orca` binary (built from v0.13 tag) |
+| **pve01** | Proxmox VE 8/9 | Bare-metal or nested; SSH root access; orca SSH key pre-staged |
+| **worker01** | Ubuntu 22.04 LTS | VM or bare-metal; SSH root access; orca SSH key pre-staged |
+
+### Alternative topology (3x Ubuntu, no Proxmox)
+
+If a Proxmox host is unavailable, run the UAT with 3x Ubuntu hosts.
+Use `--type linux` for all remote nodes. Proxmox-specific claims
+(`doctor proxmox`, PVE role, sudoers) are **skipped** in this path.
+The signoff script reports exercised vs. skipped claims.
+
+## Step-by-step UAT
+
+### Step 1: Install orca + initialize the cluster
+
+Install orca (1-liner):
+```sh
+curl -fsSL https://git.cloudinit.dev/coreci/orca/raw/branch/main/scripts/install.sh | bash
+```
+
+Initialize the cluster:
+```sh
+export ORCA_HOME=~/orca-uat
+orca init
+```
+
+**Expected**: orca init creates:
+- CA cert + server cert
+- SSH keypair (orca_ssh_key + orca_ssh_key.pub)
+- known_hosts file (empty, for TOFU capture)
+- Master key (for secrets encryption)
+- Traefik data-plane ingress (binary + systemd unit + config)
+- Localhost node registered
+
+**Pre-staging remote nodes**: `orca init` interactively prompts for remote
+host addresses and runs `ssh-copy-id` automatically (password prompt passes
+through). Enter each host (pve01, worker01) when prompted, or press Enter to
+skip. The orca public key is deployed to each host; TOFU host-key capture is
+automatic on the first `orca node join` — no manual fingerprint pinning needed.
+
+### Step 2: Onboard the Proxmox host
+
+```sh
+orca node join --type proxmox \
+  --host pve01 \
+  --ssh-user root
+```
+
+**Expected**: SSH bootstrap succeeds, orca user created, PVE role assigned, node registered as `ready` with `kind=proxmox`.
+
+### Step 3: Onboard the Ubuntu worker
+
+```sh
+orca node join --type linux \
+  --host worker01 \
+  --ssh-user root
+```
+
+**Expected**: SSH bootstrap succeeds, orca user created, drift-events dir created, node registered as `ready` with `kind=linux`.
+
+### Step 4: Verify nodes
+
+```sh
+orca node list
+orca node list --json
+```
+
+**Expected**: 3 nodes listed (localhost + pve01 + worker01), all `ready`.
+
+### Step 5: Set capacity on remote nodes
+
+```sh
+orca node capacity set --node pve01 --cpu 4 --memory 8192 --disk 100000
+orca node capacity set --node worker01 --cpu 2 --memory 4096 --disk 50000
+orca node capacity list
+```
+
+**Expected**: capacity shown for both remote nodes.
+
+### Step 6: Create a namespace
+
+```sh
+orca ns create prod
+orca ns list
+```
+
+**Expected**: `prod` namespace listed.
+
+### Step 7: Deploy the full stack
+
+Deploy each service from `examples/full-stack/`:
+
+```sh
+orca job run examples/full-stack/web-app.md --target pve01
+orca job run examples/full-stack/api.md --target pve01
+orca job run examples/full-stack/worker.md --target worker01
+orca job run examples/full-stack/postgres.md --target pve01
+orca job run examples/full-stack/log-shipper.md --target worker01
+```
+
+**Expected**: each job is scheduled on the target, systemd unit deployed via SSH-push, job status `running` or `complete`.
+
+### Step 8: Verify deployment
+
+```sh
+orca job list
+orca job list --json
+```
+
+**Expected**: all 5 jobs listed, with correct target nodes.
+
+On each remote node:
+```sh
+ssh root@pve01 systemctl status 'orca-alloc-*'
+ssh root@worker01 systemctl status 'orca-alloc-*'
+```
+
+### Step 9: Verify Traefik routes
+
+```sh
+ssh root@pve01 ls /etc/traefik/dynamic/
+ssh root@worker01 ls /etc/traefik/dynamic/
+```
+
+**Expected**: `traefik-dynamic-*.yaml` files present on nodes where jobs were deployed.
+
+### Step 10: Migrate between hosts
+
+Migrate `web-app` from pve01 to worker01:
+
+```sh
+orca job migrate web-app --to worker01
+```
+
+**Expected**: job drained on pve01, rescheduled on worker01, new systemd unit deployed.
+
+Verify:
+```sh
+orca job list
+ssh root@worker01 systemctl status 'orca-alloc-*web-app*'
+ssh root@pve01 systemctl status 'orca-alloc-*web-app*' # should be stopped
+```
+
+### Step 11: Aggregate logs
+
+```sh
+orca logs --all-nodes --job web-app --since 5m
+```
+
+**Expected**: log entries from multiple nodes.
+
+### Step 12: ACL enforcement
+
+```sh
+orca acl grant operator-1 --namespace prod --permissions read,write
+orca acl check operator-1 --namespace prod --permission read
+orca acl check operator-1 --namespace prod --permission admin
+```
+
+**Expected**: read+write allowed, admin denied (not granted).
+
+### Step 12b: Initialize the OIDC provider (for seal)
+
+```sh
+orca auth init-idp --rp-id orca.local
+```
+
+**Expected**: Dex config + systemd unit + Traefik route rendered. (Dex binary must be installed separately.)
+
+### Step 13: Seal/unseal
+
+```sh
+orca cluster seal
+orca cluster unseal
+orca secrets set prod TEST_KEY=test-value
+orca secrets get prod TEST_KEY
+```
+
+**Expected**: seal succeeds, unseal succeeds, secrets readable post-unseal.
+
+### Step 14: Audit chain
+
+```sh
+orca doctor audit
+```
+
+**Expected**: chain head reported, no tamper detected.
+
+### Step 15: Doctor modes
+
+```sh
+orca doctor modes
+```
+
+**Expected**: all file modes correct, exit 0.
+
+### Step 16: OIDC health
+
+```sh
+orca doctor oidc
+```
+
+**Expected**: Dex unit active, issuer reachable (or WARN if Dex not installed).
+
+### Step 17: Backup and restore
+
+```sh
+orca backup --out /tmp/uat-backup.tar.gz
+orca restore --in /tmp/uat-backup.tar.gz --dry-run
+```
+
+**Expected**: backup succeeds, restore dry-run succeeds.
+
+### Step 18: Drift detection
+
+```sh
+orca drift show
+```
+
+**Expected**: no error (empty drift is fine).
+
+### Step 19: Transaction idempotency
+
+```sh
+orca txn apply <some-txn-dir>
+orca txn apply <some-txn-dir>  # re-run
+```
+
+**Expected**: second apply is idempotent (exit 5 or "already applied").
+
+### Step 20: Metrics
+
+```sh
+orca metrics --addr :9100 &
+sleep 3
+curl -s http://localhost:9100/metrics | grep orca_
+```
+
+**Expected**: expanded metric set present (`orca_jobs_running`, `orca_audit_chain_head`, etc.).
+
+### Step 21: Compat check
+
+```sh
+orca cluster compat-check
+```
+
+**Expected**: exit 0, all nodes compatible.
+
+### Step 22: Run the signoff script
+
+```sh
+scripts/uat-signoff.sh
+```
+
+**Expected**: `UAT SIGNOFF: N/35 assertions passed`, exit 0 iff N==35.

+
+
+## Troubleshooting
+
+### ORCA_HOME not set
+All orca commands use `$ORCA_HOME` (default `~/.orca`). If commands fail
+with "no such file or directory", verify:
+```sh
+echo $ORCA_HOME
+ls $ORCA_HOME/orca.db $ORCA_HOME/orca_ssh_key $ORCA_HOME/known_hosts $ORCA_HOME/cluster/master.key
+```
+
+### known_hosts missing
+If SSH operations fail with "open .../known_hosts: no such file", the
+known_hosts file was not created during `orca init`. Fix:
+```sh
+touch $ORCA_HOME/known_hosts
+chmod 600 $ORCA_HOME/known_hosts
+```
+
+### Traefik not running
+If Traefik routes are not deployed, verify Traefik is running:
+```sh
+systemctl status orca-traefik
+ls /etc/traefik/dynamic/
+```
+If not installed, `orca init` should have installed it. Re-run `orca init`
+or install manually from https://github.com/traefik/traefik/releases.
+
+### SSH connection refused
+If the orca SSH key is not pre-staged on the remote host:
+```sh
+ssh-copy-id -i ~/.orca/orca_ssh_key.pub root@<host>
+```
+
+### Job deployed but not visible in `job list`
+The remote dispatch path now inserts a DB record (v0.12.16). If you
+still don't see it, check:
+```sh
+orca job list --json
+```
+Look for the `"node"` field — it shows which node the job deployed to.
+
+### Proxmox: process runtime rejected
+Proxmox nodes require `one_of: pve-ct` or `one_of: pve-vm` in the
+jobspec. `one_of: process` (systemd) is for Linux/Ubuntu workers only.

+
+The WebAuthn connector ships as part of the v0.12 milestone (P05) and
+is operationally wired in v0.13 (P04: registration requires auth; P06:
+real Dex deployment).
 
 ## Registration
 
-`orca auth register` opens the browser to the Dex WebAuthn endpoint.

+via an existing session or admin bootstrap token, then performs the
+WebAuthn ceremony (biometric or security key). After the ceremony,
+Dex maps the credential ID to an OIDC `sub`.
+
+- **`--no-browser`**: print the registration URL instead of opening a

+Verifies the bundled Dex OIDC provider is running and the
+`/.well-known/openid-configuration` endpoint responds. Run after
+`orca auth init-idp` or after a Dex config change.
+
+## Security properties
+
+- **No passwords**: WebAuthn is password-free. No password is ever
+  sent to or stored by orca (R-021).
+- **Phishing-resistant**: the WebAuthn protocol cryptographically binds
+  the ceremony to the RP ID, defeating credential phishing.
+- **Private key never leaves the authenticator**: orca stores only
+  public keys.
+- **Secure context required**: HTTPS via step-ca / Traefik (C-38).
