 # Agent environment orientation
 
 **Audience:** every coding agent working in this estate (Claude Code, Codex, Grok, custodian workers). It is tool-neutral.

 These are facts about the *environment*: where things run, how to reach them, and the traps that cost real time. Each section names its owner. When a fact changes, fix it here and in the owner's record.

-**Trap (fixed on the workstation 2026-09-22):** `BAO_ADDR`/`VAULT_ADDR` used to default to `https://bao.coulomb.social`, which is **unreachable**: it resolves to railiance01, but Traefik serves its default self-signed certificate there and no route matches the host (`-k` still gives 404). `~/.bashrc` now exports `http://127.0.0.1:18200` for both. A shell opened before that change, or any other host, still needs the prefix on every `bao` command. Whether the public name should exist at all is railiance-platform's call (hub message `e8ccbc2f`).
+**Retired name:** `bao.coulomb.social` is **retired**, not a trap to work around. Its public Ingress was retracted on 2026-09-15 (railiance-master RMASTER-WP-0020-T09); the self-signed Traefik cert and the 404 are leftovers of a dangling DNS record, and DNS withdrawal sits with railiance-infra. No certificate or route will be restored (railiance-platform RPF-WP-0025-T03). Operators use the tunnel `http://127.0.0.1:18200`, which `~/.bashrc` has exported as `BAO_ADDR`/`VAULT_ADDR` since 2026-09-22; workloads use `openbao.openbao.svc:8200`. A shell opened before that change still needs the prefix.
