…Cad 10; refactor command timeouts - ipc_backend: attempt the native ParseAndCreateItemsFromString path for footprint placement first, falling back to a save/reload compatibility path since KiCad 10's PCB handler for that command currently returns an empty response. Guard pcbnew.SaveBoard calls with preserve_project_settings so a board save can no longer clobber .kicad_pro net_settings. - freerouting: support a FREEROUTING_JAVA environment override for locating the Java executable used to run the router. - command-timeout: extract per-command timeout policy into a pure, unit-testable computeCommandTimeout() (src/command-timeout.ts), with an autoroute-aware budget instead of a flat ceiling; add open_project and create_project to the long-running command list.
…outer tools Adds four tools that close the gaps hit while manually converting a real 33-net, ~150-wire schematic from net-labels to point-to-point wiring: - get_schematic_symbol_bbox: absolute-coordinate bounding box (body + pins) for one or more symbols, computed via the same lib_symbols-graphics logic find_wires_crossing_symbols already used internally, now exposed directly so a route can be planned from real geometry instead of guessing from pin coordinates alone. - add_schematic_wire dryRun: preview a candidate wire's symbol crossings and collisions with wires on a different net without writing anything. The different-net check is new: own-net is resolved once from the file's pre-existing state (exact-IU wire endpoint match, by component id rather than net name so unnamed nets are handled correctly too), and any existing wire on a different net that the candidate path would touch is reported rather than silently written. - check_schematic_connectivity: fast same-net check between two points/pins using the existing strict, vertex-exact wire_connectivity BFS, instead of shelling out to a full kicad-cli ERC just to sanity-check one connection. - connect_schematic_pins: orthogonal auto-router for 2+ pins. Builds a coordinate-compressed local grid (obstacle edges + uniform fill) around each pin pair and A*-searches it with a bend penalty, avoiding symbol bodies and foreign-net wires; 3+ pin nets use sequential nearest-pin insertion. Blocked-edge lookups are precomputed per obstacle rather than rescanned per edge during search — the naive per-edge scan was fast on synthetic test fixtures but took 30+ seconds against a real, busy sheet with ~250 existing wires/symbols; precomputing brought that under 1.5s. Shared groundwork: _load_wire_net_membership (wire_connectivity.py) classifies every wire on a sheet into its net in one pass instead of one BFS per query point/net; _load_obstacle_model (schematic_analysis.py) is a refactor-for-reuse of find_wires_crossing_symbols's own per-symbol bbox precomputation, now shared by the dry-run check and the router.

Reviewed — and this needs a split before it can be reviewed properly, because the title describes maybe half the diff. The buried half is the problem. python/kicad_api/ipc_backend.py alone is ~740 lines of this diff — a wholesale kipy-0.7 rewrite — and its base blob is pre-#369, so it reimplements get_open_board_path differently from the version that merged with tests on Aug 9. Merging as-is would either conflict loudly or, resolved carelessly, silently replace a tested implementation with an untested near-duplicate. It also collides head-on with #378, which touches the same functions with a different approach; only one PR can own the kipy-0.7 story, and that decision should not be forced through a PR titled 'schematic tools'. The '1829 passed' claim also cannot be current — it was run against a base that is now several weeks stale. The good news: the title half is genuinely useful, and its registry hygiene is correct (all three tools registered, first README count bumped). Concrete ask — split into three:
The freerouting.py and command-timeout.ts changes are unexplained in the body — justify or drop them in whichever split they belong to. |

Closing for now. The split asked for on 2026-08-20 (the symbol-bbox / dry-run collision check / connectivity check trio separated from the kipy 0.7 rewrite of ipc_backend.py) did not get a reply, and the branch is now 88 commits behind main with conflicts in src/server.ts, python/kicad_api/ipc_backend.py and README.md, so it cannot be merged as it stands. The three schematic tools are still wanted: a fresh PR with just them, rebased on main, gets a prompt review. The ipc_backend half should not come back in that PR; #369 already fixed get_open_board_path with tests, and the kipy compatibility work has its own thread in #378. |

Summary
get_schematic_symbol_bbox: returns absolute-coordinate bounding boxes (body + pins) for requested symbol references.add_schematic_wiregains adryRunmode: reports symbol crossings and foreign-net collisions before writing anything.check_schematic_connectivity: fast same-net check between two points (pin or x/y), without a full ERC run.connect_schematic_pins: new auto-router (python/commands/schematic_router.py) that A*-routes orthogonal wires between 2+ pins on a coordinate-compressed grid, avoiding symbol bodies and foreign-net wires, with own-net conflict detection and multi-pin sequential nearest-insertion.Motivation: while manually converting a real schematic sheet from net-labels to point-to-point wires, the biggest bottlenecks were no visibility into symbol geometry, no way to detect a wire silently shorting two nets before writing it, and no fast same-net check. These tools close those gaps and add a first-pass auto-router.
