Andrey Avtomonov feb0818444 feat(cli): self-provision pinned uv and defer MCP Python runtime install (#297) ... Fixes a production crash-loop (PostHog issue 019eb68e): ktx mcp start --foreground on a uv-less container eagerly installed the managed Python runtime at boot, failed, and was restarted by its supervisor every ~62s (122 exceptions from one install). - MCP server factory now wires a lazy semantic-layer compute port that defers the runtime install to the first call, mirroring the already-lazy SQL-analysis port; the server boots and serves non-Python tools without the runtime. - ktx no longer requires uv on PATH: it downloads its own pinned, sha256-verified uv build under the runtime root (KTX_RUNTIME_ROOT aware), always musl-static on Linux. PATH uv is never consulted. - uv is acquired before the version dir is wiped, so a failed download cannot destroy an existing runtime. - Acquisition failures (offline, intercepted download, unsupported platform) throw KtxExpectedError and stay out of Error Tracking; a missing binary inside a checksum-verified archive remains a plain Error. - scripts/refresh-uv-manifest.mjs regenerates the pinned manifest (packages/cli/src/managed-uv-release.ts) on uv bumps. - Setup consent prompt now discloses the uv download; docs updated.		2026-06-12 16:31:06 +00:00
