Gateway first turn no longer waits on the Python toolchain probe (#106064, salvage #106075) - #106556

Conversation
The gateway's startup warm-up (_warm_turn_machinery_sync) primed the run_agent import graph, tool schemas and context files, but left the process-local Python toolchain probe to the first AIAgent. That agent starts the probe worker in its constructor and its first system-prompt build then blocks in get_environment_probe_line() on the python/pip subprocesses (~250 ms measured) before the first model request — with local models too, so provider metadata warm-up (#105999) does not cover it. Call the same resolver from the warm-up: it owns the agent.environment_probe opt-out check here, and the resolver itself owns remote-backend omission, the single worker, its cache and the bounded fail-open wait, so the first turn simply finds the line cached. No agent is constructed and no session prompt is frozen at startup; a disabled probe or a remote terminal backend leaves the host untouched. Slim redo of #106075 by @francip: same mechanism, folded into the existing sync warm-up instead of a new module + asyncio.gather + second suppress block; the two behavior tests are kept, the concurrency tests dropped.

This release closes that class and rolls up everything else that landed on `main` in the four days since v0.21.1. ##### About this release Measured at commit `04dd80a977f40b05e5b2054111747af07a61886a`, the window since v0.21.1 contains **947 non-merge commits** across **1,869 changed files** (+182,504 / −15,564) and **312 merged PRs**. **140 contributors** appear in commits, co-author trailers, or salvage credits. ##### ✨ Highlights ##### state.db reliability campaign (six PRs, 44 issues closed) If your `state.db` broke after 0.21.0, this is the release for you. Six PRs fix the root causes rather than the symptoms: - **No more second writers.** Profile gateways wrote hosted-room state into the *root* `state.db` every 5 seconds; the dashboard opened a writable handle on startup; cron's lifecycle guard did a raw `open()` on a live database (which cancels the gateway's POSIX locks — the classic "how to corrupt SQLite" recipe); `doctor --fix` would checkpoint under a live holder. All four are gone: hosted rooms live in `shared-state.db`, the dashboard opens read-only first, the guard goes through the tracked connection registry, and `doctor --fix` refuses a checkpoint it can't prove is safe.

The gateway's first inbound turn no longer blocks on the Python/pip toolchain probe: the boot warm-up primes it, so the first system prompt finds the line cached.
gateway/run.py::_warm_turn_machinery_syncnow callsget_environment_probe_line()after tool schemas + context files, gated onagent.environment_probe(default on). The resolver itself owns remote-backend omission (ssh/docker/… →"", host untouched), the single worker, its cache, and the bounded fail-open wait, so nothing is duplicated.AIAgentis constructed and no session prompt/memory/tools are frozen at startup; disabled probe or remote terminal backend leaves the host untouched; a slow probe still hits the existing bounded warm-up gate (HERMES_STARTUP_WARMUP_TIMEOUT) exactly like the rest of the warm-up.tests/gateway/test_startup_environment_probe.py: two invariants — enabled+local → probe cached after warm-up (red on main); disabled or remote → host never inspected.Live repro
Fresh process, temp
HERMES_HOME(agent.environment_probe: true,terminal.backend: local), real python/pip subprocesses; runs_warm_turn_machinery_sync()exactly as the boot warm-up does, then constructs anAIAgentand builds its first system prompt, timing the wait insideget_environment_probe_line()(3 runs each):Toolchain line present in the prompt in both arms (identical content); provider metadata warm-up (#105999) present in both.
Root cause:
_warm_turn_machinery_syncwarmed imports, tool schemas and context files but never the toolchain probe, so the firstAIAgentstarted the worker and its first prompt build waited on it.vs #106075
Slim redo of #106075 by @francip — same mechanism and gating, folded into the existing sync warm-up instead of a new
gateway/run_startup_environment.pymodule +asyncio.gather+ second_log_suppressedblock; 58 lines vs 163. His two behaviour tests are kept as the two invariants; the concurrency/bounded-gate tests are dropped because the probe now rides the already-tested warm-up gate. Contributor email mapping cherry-picked from his PR;Co-authored-byon the fix commit.Credit: @francip (issue #106064 diagnosis, PR #106075).
Closes #106064
