Listener auth (kb#180, DESIGN-a2a-agents.md §4)
-----------------------------------------------
agap-mcp binds :3100 on every interface (network_mode: host) and the LAN
carries VPN-terminated peers, so an unauthenticated JSON-RPC listener handed
ha_call_service / gitea_wiki_write / wiki_edit / radicale+todoist writes and
POST /capture-idea to any LAN peer. Only vw_* was gated before (kb#147), and
only at ENFORCE=1.
src/listener-auth.js now requires `Authorization: Bearer <token>` resolving to
a known agent id on every route except /health, which stays open so a
misconfigured token map is still diagnosable. Two gates stay deliberately
layered and independently switchable: "are you an agent at all?" (this file)
vs "are you trusted enough for the vault?" (trust-gate.js), both reading the
same token map.
Also closes an SSE session-hijack hole: /messages previously trusted any
sessionId with no credential, so a guessed or leaked id was full tool access.
Sessions are now pinned to the caller identity captured at the /sse handshake,
comparing agent id *and* token.
Auth defaults ON, and boot fails loudly if the token map is empty rather than
serving 401 to everyone while /health reports ok. Rollback is
AGAP_MCP_REQUIRE_AUTH=0.
Verified live: unauthenticated and bad-token /mcp -> 401, unauthenticated
/capture-idea -> 401, /health -> 200, both real agent tokens -> 200 with 36
tools, including from inside the adolf container.
Pin the bw CLI
--------------
The Dockerfile installed @bitwarden/cli unpinned. Rebuilding jumped
2026.2.0 -> 2026.7.0, whose WASM cipher deserializer rejects any stored login
carrying `"uri": null` ("invalid type: JsValue(Object({...})), expected a
string") -- 33 of 49 items in this vault have that shape. `bw list` then exits
1, server init fails, and the container crash-loops. Pinned to 2026.2.0.
Do not unpin: 2026.7.0 cannot authenticate against this Vaultwarden
(2025.12.0) at all -- it refuses plain HTTP outright and 404s on the identity
endpoint over HTTPS. Updating the CLI requires upgrading Vaultwarden first.
capture / classifier
--------------------
Adds the POST /capture-idea REST endpoint and the idea classifier behind it
(consumed by the todoist-capture plugin), with tests. Carried in the same
commit because server.js wires both this and the auth boot path.
