fix: resolve discourse-mcp TS2345 build error and add env-var auth

The discourse-mcp was BLOCKED with a TypeScript TS2345 error caused by
the Dockerfile forcing SDK ^1.23.0 via `pnpm add`, while the upstream
code requires the lockfile's v1.17.3. Removed the override to use
`pnpm install --frozen-lockfile`.

The upstream server does not read environment variables directly — it
requires CLI args (--auth-pairs, --site) or a --profile JSON file. Added
a docker-entrypoint.sh that converts DISCOURSE_URL, DISCOURSE_API_KEY,
and DISCOURSE_API_USERNAME env vars into a profile JSON with auth_pairs
and site tethering.

Validated end-to-end: MCP handshake passes, site auto-tethers on startup,
live tool calls (discourse_search, discourse_filter_topics) return real
data from community.turnsys.com.

Updates STATUS.md and README.md to reflect discourse-mcp as production
ready. Adds JOURNAL.md entries for discourse-cli, discourse-mcp fix, and
protocol improvements.

+### [ADR] discourse-cli: Standalone CLI for Discourse (following redmine-cli pattern)
+
+**Date/Time**: 2026-07-30 5:50 PM EST
+**Type**: Implementation
+**Status**: Accepted
+
+**Context**: The existing discourse-mcp was BLOCKED (TS2345 build error), but
+the redmine-cli pattern (standalone CLI container, on-demand via docker run)
+provides a reliable alternative for Crush (which has Docker/CLI access).
+
+**Decision**: Built discourse-cli/ as a standalone Python CLI with full read/write
+coverage: whoami, categories, topics, show, create, reply, update, delete, search,
+notifications. Uses requests library with JSON body encoding for POST/PUT/DELETE.
+Validated 10/10 against community.turnsys.com.
+
+**Key insight**: Python `requests` with `data={nested}` stringifies dicts instead
+of form-encoding them. Must use `json=data` for nested payloads to Discourse API.
+The `/session/current.json` endpoint doesn't work with API keys (returns 403);
+use `/notifications.json` or `/u/<username>.json` instead for connection tests.

+### [ADR] discourse-mcp: Fixed TS2345 build error
+
+**Date/Time**: 2026-07-30 5:50 PM EST
+**Type**: Bug Fix
+**Status**: Accepted
+
+**Context**: discourse-mcp was BLOCKED with TypeScript TS2345 error in
+src/tools/remote/tool_exec_api.ts:58. The Dockerfile was forcing
+`@modelcontextprotocol/sdk@^1.23.0` via `pnpm add`, but the upstream code
+is only compatible with the lockfile's SDK v1.17.3.
+
+**Decision**: Removed the `pnpm add @modelcontextprotocol/sdk@^1.23.0` line
+from the Dockerfile. Using `pnpm install --frozen-lockfile` instead.
+
+**Additional fix**: The discourse-mcp server does NOT read environment variables
+directly. It requires CLI args (`--auth-pairs`, `--site`) or a `--profile` JSON
+file. Added a docker-entrypoint.sh that converts DISCOURSE_URL/API_KEY/API_USERNAME
+env vars into a profile JSON file with auth_pairs and site tethering.
+
+**Key insight**: The upstream server's `buildAuth()` returns `{type: "none"}`
+by default. Auth comes from auth_pairs overrides in the profile. The `select_site`
+tool is needed when not tethered; when `--site` is provided, the server preselects
+the site and hides the select_site tool.
+
+Validated with MCP handshake + live tool calls (search, filter_topics) against
+community.turnsys.com.
+
+### Protocol Fix: Honest status reporting + one-server-at-a-time
+
+**Date/Time**: 2026-07-30 5:50 PM EST
+**Type**: Process Improvement
+**Status**: Accepted
+
+**Context**: AI agents were marking services as "validated" after only running
+structural tests (build + --help) without live credentials. Also attempting to
+validate multiple MCP servers in parallel, never finishing any.
+
+**Decision**: Added two mandatory rules to AGENTS.md:
+1. Honest status reporting: distinguish "built" vs "structural test" vs "validated"
+2. One server at a time: build → handshake → live client invocation → status → commit
+   before starting the next server.

 ### discourse-mcp
-BLOCKED - Build failed with TypeScript TS2345 error in upstream repository (src/tools/remote/tool_exec_api.ts:58). The code is incompatible with MCP SDK types. Cannot fix locally without upstream changes.
+FIXED - Build was failing due to Dockerfile forcing `@modelcontextprotocol/sdk@^1.23.0` via `pnpm add`, which is incompatible with upstream code (locks SDK to v1.17.3). Removed the `pnpm add` override, using `pnpm install --frozen-lockfile` instead. Also added a docker-entrypoint.sh that converts env vars (DISCOURSE_URL, DISCOURSE_API_KEY, DISCOURSE_API_USERNAME) into a profile JSON file with auth_pairs and site tethering. The server does not read env vars directly — it requires CLI args or a profile file. Validated with MCP handshake + live tool calls (search, filter_topics) against community.turnsys.com.
 
 ### proxmox-mcp
 Fixed by patching pyproject.toml to use 'fastmcp' from PyPI instead of 'mcp @ git+...' and updating imports from 'mcp.server.fastmcp' to 'fastmcp'. Container now builds and runs - requires PROXMOX_MCP_CONFIG env var pointing to a valid config file.
