The instruction surface named a parameter the tool refuses. bridge_ack requires
target and msgId (BridgeMcp.java:1001) and errors with 'target and msgId are
required' otherwise, but step 5 of the primary procedure said bridge_ack{ticket,
msgId}. The table two sections below it was already correct, so the file
contradicted itself and the wrong half was in the numbered steps a lead follows.
The same line is fixed in the byte-identical wiki template.
docs/MCP-Contract.md still opened with 'Greenfield - no MCP code exists yet' and
CLAUDE.md pointed every session at it. Audited against BridgeMcp.java: it names
two tools that do not exist, omits four that do, gets nearly every parameter name
wrong, and uses /workers paths the daemon does not serve. Its status banner now
says so and names the live schema as the authority; CLAUDE.md's pointer is
narrowed to section 6, which is the part that did survive. Rewrite is CB-609.
