docs: replace the decommissioned ollama.ltms.dev host

A page audit found the dead host still named in four places outside the wiki.
ollama.ltms.dev no longer exists; the one front door is llm.ltms.dev, and the
path differs by backend - /anthropic for claude-code, /v1 for opencode.
Anyone following README.md today points a member at nothing.

README.md also now links the new wiki chapter 13, the operator guide, since
the README's own next step used to be the never-written Setup page.

Not touched: SubscriptionGuard.java:14 still names ollama.ltms.dev, but only
in a javadoc line describing the Stage-1 example allowlist. It is a comment
about history, not a live default, so it stays until that class is next
edited for its own reasons.

 # MCP Contract — `bridged`'s unified gateway
 
-> **Status:** 🟡 Design (2026-07-14). Greenfield — no MCP code exists yet; the pom carries
-> only Javalin/Jackson. This page defines the tool surface that CB-104 and its followers
-> implement. It supersedes nothing; it fills the "MCP server face" left open by the
-> [Architecture](1-Architecture) page.
+> **Status: 🔴 HISTORICAL DESIGN — do NOT use as the tool reference.** Written 2026-07-14, before
+> any MCP code existed. The system shipped and this page never caught up, so **its tool names,
+> parameter names and REST paths are wrong today**. Audited 2026-08-17; the specific drift:
+>
+> - **Tools it names that do not exist:** `bridge_read`, `bridge_cancel`.
+> - **Shipped tools it omits:** `bridge_poll`, `bridge_ack`, `bridge_profiles`, `bridge_whoami`.
+> - **Parameter names are wrong nearly everywhere** — it says `message`/`target`/`timeout_seconds`/
+>   `block` where the code takes `content`/`sessionId`/`timeoutMs`/`wait`; `text` where
+>   `bridge_reply` takes `content`; `target` where `bridge_stop` takes `paneId`.
+> - **REST paths are wrong:** it says `POST /workers` and `DELETE /workers/{paneId}`; the daemon
+>   serves `POST /members` and `DELETE /members/{paneId}`.
+>
+> **The authoritative tool surface is the live MCP schema** (each tool's own description and
+> parameters, as mounted), with the intent→tool table in `CLAUDE.md` as the short form. Both were
+> checked against `mcp/BridgeMcp.java` on 2026-08-17 and are accurate.
+>
+> What is still worth reading here is **§6 — the flows and the error model** (rendezvous,
+> `bridge_ask`, detached delivery, the turn-done fallback). The shapes it describes are the ones
+> that shipped; only the names around them drifted. Rewriting this page is tracked as **CB-609**.

+#
+# CB-596 step 1: measure which credentials a live member actually holds.
+#
+# The claim under test is that a member's herdr pane starts a LOGIN shell, that shell sources
+# ${SHARED_ENV}/tools/secrets.sh, and so a member inherits every name that file exports — while
+# CB-592 blocks exactly one of them (GITEA_ACCESS_TOKEN). That is an inference from the code, not a
+# measurement, and issue #82 says plainly: do not build a fix on the inference. This is the
+# measurement.
+#
+# WHY THIS IS A SCRIPT AND NOT A COMMAND SOMEONE TYPES
+#
+# Enumerating credential names inside a member is exactly the action that should need the operator's
+# explicit approval, and the command classifier refuses it. That refusal is correct. This script is
+# the seam: it is one auditable file the operator can read once, top to bottom, and then run — rather
+# than approving an ad-hoc shell pipeline whose behaviour they have to take on trust.
+#
+# WHAT IT WILL NOT DO
+#
+#   * It never prints a credential value, and never any prefix or suffix of one. Not one character.
+#     Issue #82's criterion 1 asked for a 6-character prefix; this prints a truncated SHA-256 instead.
+#     A prefix of a short secret is most of the secret, and it would end up pasted into a ticket. The
+#     hash answers every question the prefix was for — is it set, is it the same value as over there,
+#     is it the CB-592 sentinel — and answers none of the ones it should not.
+#   * It never writes anywhere, never contacts the network, and never touches secrets.sh, which is
+#     the operator's file.
+#
+# HOW TO RUN IT
+#
+#   1. As the operator, in a member's pane (a spawned worker's terminal):
+#        bash scripts/probe-member-credentials.sh
+#   2. For the comparison row, in your OWN shell — a lead, not a member:
+#        bash scripts/probe-member-credentials.sh --allow-outside-member
+#
+# The two outputs side by side are the finding: any name whose hash matches between them is a
+# credential the member holds in full.
+#
+set -uo pipefail
+
+# The names ${SHARED_ENV}/tools/secrets.sh exports, recorded on 2026-08-16 (issue #82). Names only —
+# this list contains no values and never should. If secrets.sh gains a name, this list goes stale and
+# the probe silently stops asking about it; that staleness is itself part of what #82's criterion 4
+# has to solve, so it is called out in the summary rather than hidden.

+  * GITEA_ACCESS_TOKEN is the control. CB-592 replaces it with a blocked sentinel, so its hash
+    should DIFFER between the two readings. If it matches, CB-592 is not working and that is the
+    most urgent thing on this page.
+  * AI_GATEWAY_TOKEN matching is expected and correct, not a leak: bridged.yaml names it in
+    `tokenEnv:` for the local and gx profiles, so a member reaching the gateway is by design.
+  * A name that is set here but is NOT in the list above will not appear at all. The list was
+    recorded on 2026-08-16 and does not update itself. Anything added to secrets.sh since then is
+    invisible to this probe — which is the same gap issue #82 criterion 4 asks to close properly.
