 | `offboxCeremonyWaitState` + `escrowCeremonyGraceWindow` | controller/internal/web/handlers.go | pure pick: (awaiting, timedOut) from `OffboxTarget.{EscrowState,CeremonyCompletedAt}` — the v0.138.0 "megerősítésre vár" card. Stamp SET on claim (escrow_handlers.go), CLEARED on the flip (main.go Flip + offbox_handlers.go manual confirm) | escrow_wait_state_test.go truth table (escrowed/unstamped/unparseable → plain CTA; boundary via `>=`) |
 | `Manager.sambaUpFn` / `sambaPasswdFn` / `sambaRunFn` / `sambaAddrFn` (func seams) | controller/internal/stacks/manager.go (fields) + samba.go | nil → `composeUp` / `docker exec smbpasswd` (STDIN) / `containerRunning("felhom-samba")` / `docker exec felhom-samba ip -4 -o addr show eth0` | injected in controller/internal/stacks/samba_test.go — the idempotency test asserts the up-seam is called **zero** times when config is unchanged; the passwd seam means no unit test ever handles a real secret or touches docker. **`sambaRunFn` has an EXPORTED setter (`SetSambaRunProbe`)** — internal/web's status-contract tests need a live-container world from another package. `sambaAddrFn` backs `SambaLANAddress()` (v0.151.0); its parse is separately pinned in samba_lanaddr_test.go and it returns "" on any failure — the page omits a line rather than printing a wrong address |
 | `volumeCopier` + `Manager.undoCopier` / `updateUndoHealthFn` (v0.263.0) | controller/internal/stacks/undo.go | nil → `dockerVolumeCopier` (alpine helper: `cp -a` named volume → `<vol>.pre-update-<stamp>`, finished-marker LAST; restore re-checks the marker in the same shell) / nil → `waitUpdateHealthyMeta` with the OLD `.felhom.yml` | `fakeCopier` in controller/internal/stacks/undo_test.go — volume CONTENT as strings, so "the data came back" is a compare; a cut-off copy is a copy without its marker. **Judge a copy by the helper's own exit + the marker, never by the client** (killing `docker run` leaves the container copying — measured) |
+| `pgConverter` + `Manager.pgConv` / `convertFreeFn` (v0.273.0) | controller/internal/stacks/pgconvert.go | nil → `dockerPGConverter` (docker exec psql/pg_dumpall over 127.0.0.1 — the entrypoint's temporary init server listens on the socket only; `Empty` re-checks the undo copy's marker in the same helper) / nil → statfs of the stack dir | `fakePG` in controller/internal/stacks/pgconvert_test.go — works on `fakeCopier`'s volume strings. **Never convert without the ladder's `engine_conversion` mark** (`planEngineConversion` refuses a PostgreSQL major move without it); `isPostgresImage` must match `appbackup.dbTypeForImage` (pinned by a source-reading test) |
 | `Manager.SambaLANAddress()` | controller/internal/stacks/samba.go | `() string` — the guest's LAN IPv4 for the Megosztás connect card (v0.151.0, S-2) | Read from the SAMBA container's netns (`network_mode: host`), never `net.InterfaceAddrs()` — the controller is on a docker BRIDGE and would answer 172.x (the same trap `setup.DetectLocalIPs` needs `HOST_IP` for). **NEVER cache/persist it** — the guest holds it by DHCP (S-5); callers re-derive per render. `""` = omit the line |
 | `Server.sambaAddrFn` (func seam) | controller/internal/web/server.go (field) + sharing_handlers.go `sambaLANAddress()` | nil → `stackMgr.SambaLANAddress()` | The web-side half of the connect card. Tests inject a COUNTED fn — the fresh-per-render assertion is what stops anyone memoizing a DHCP lease |
 | `Manager.guestNetExecFn` (func seam) + `GuestGateway()` / `GuestNetSnapshot()` | controller/internal/stacks/manager.go (field) + guestnet.go | nil → `docker exec felhom-samba <args>` — ONE seam for all R-66 guest-netns reads (route/link/addr/resolv.conf); tests script canned outputs per argv | guestnet_test.go. **The netns door rule:** the controller's OWN netns is the docker bridge, so any in-process read (`net.Interfaces`, `/proc/net/route`, its own `/etc/resolv.conf` = 127.0.0.11) is the S-2 wrong answer — guest-net reads MUST go through the samba (`network_mode: host`) exec door. Megosztás off ⇒ door closed ⇒ "" / per-item error strings; NEVER substitute an in-process value. Same S-5 law as SambaLANAddress: live per render, never cached/persisted. Parsers (`parseDefaultRoute`, `parseGuestInterfaces`, `parseResolvConf`) are pure + separately pinned |
