PWR_FLAG instances use a #FLG reference prefix, not #PWR, so their
pin positions were never registered as virtual connection anchors in
_parse_virtual_connections. As a result, find_orphaned_wires reported
wire ends terminating on a PWR_FLAG as dangling. Other call sites
(schematic_analysis.py:127, kicad_interface.py:3814) already recognize
#FLG as a power symbol; align this site with them.
Also coerce a previously-validated Optional[int] to int in board/layers.py
so the file passes mypy (required by the pre-commit hook); behavior is
unchanged because the value is already None-checked above.

Adds robust multi-sheet (hierarchical) net connectivity for KiCad
schematics and switches the wire/label parsing to a direct sexpdata
pipeline that bypasses kicad-skip's collection iteration, which was
silently dropping wires, labels, and symbol instances on real-world
schematics.
python/commands/wire_connectivity.py
- New sexpdata helpers: _load_sexp, _parse_wires_sexp,
_parse_labels_sexp, _parse_symbol_instances_sexp,
_parse_hierarchical_labels_sexp, _discover_sub_sheets.
- _build_adjacency now detects T-junctions (endpoint landing on
another wire's interior segment) so adjacency captures connections
KiCad doesn't represent as separate wire segments.
- _find_connected_wires gains an interior-segment fallback so labels
placed mid-wire still seed BFS correctly.
- _parse_virtual_connections gathers label / global_label /
hierarchical_label and power-symbol pin positions, with a
kicad-skip fallback for unit tests that mock the schematic.
- _find_pins_on_net rebuilds pin positions from sexpdata symbol
instances (with mirror_x/mirror_y/rotation handling) and uses a
plus/minus 1 IU tolerance for floating-point edge cases.
- get_connections_for_net walks the top sheet plus every recursively
discovered sub-sheet, deduping pins across sheets.
python/commands/pin_locator.py
- lib_id matching now falls back to a bare-name + unit-suffix match
so instances like "stat-tis-custom:BAT_18650" resolve to
lib_symbols entries like "BAT_18650_3".
- Pin position math now y-negates lib_symbols coords, applies
mirror_x/mirror_y in local coords before rotation, and propagates
the same transform into get_pin_orientation so downstream callers
get a correct outward angle for mirrored symbols.
python/commands/connection_schematic.py
- generate_netlist now collects nets from both label and
global_label and routes them through get_connections_for_net so
netlists reflect cross-sheet connectivity instead of single-sheet
label-only nets.
python/kicad_interface.py
- list_schematic_nets aggregates net names across the top sheet and
all sub-sheets via the sexp helpers, then resolves connections
using get_connections_for_net.
- get_net_connections delegates to get_connections_for_net for
consistent multi-sheet results.
Mechanical application of the `.gitattributes` rules from the prior commit.
All 50 files differ only in line endings — verified by
`git diff --cached --ignore-all-space` being empty.
Before: main had 42 CRLF + 27 LF Python files plus mixed-ending in YAML,
templates, and shell scripts. After: every text file is LF (except the
Windows-native *.ps1, *.bat scripts which remain CRLF per gitattributes).
This eliminates the noisy-diff failure mode seen in PR #102, where a
small logic change produced a 918-line diff due to whole-file CRLF→LF
conversion.
get_pin_net was a superset of get_wire_connections with the same
coordinate-based flood-fill but two extra response fields (net, query_point)
and a reference+pin input mode. Having both tools confused LLM tool selection.
get_wire_connections now:
- Returns net (label name or null) and query_point in all response paths
- Accepts reference+pin input in addition to x/y coordinates,
resolving the pin endpoint via PinLocator internally
get_pin_net tool, handler, schema, TS registration, and tests removed.
test_wire_connectivity.py updated with coverage for all new behaviour.

Answers "what net is pin X of component Y on?" without requiring
callers to triangulate from list_schematic_nets or know a wire
coordinate first.
Accepts either {reference, pin} (resolved via PinLocator) or {x, y}
coordinate. Returns net label name (or null for unnamed nets), all
connected pins, wire segments, and the resolved query point.

Add type annotations to all previously untyped functions and remove 9
suppressed error codes (call-arg, assignment, return-value, operator,
has-type, dict-item, misc, list-item, annotation-unchecked) by fixing
the underlying type issues.
Add [[tool.mypy.overrides]] with ignore_missing_imports for KiCAD-specific
modules (pcbnew, sexpdata, skip, cairosvg, kipy, PIL) so the pre-commit
mypy hook passes in its isolated venv. Add types-requests and pytest to
additional_dependencies in .pre-commit-config.yaml.
Also fixes several real bugs uncovered by stricter checks: incorrect static
calls to instance methods in swig_backend, wrong return type on get_size,
missing value param in BoardAPI.place_component, variable shadowing in
kicad_process.py, unqualified LibraryManager reference in kicad_interface,
and missing top-level Path import.

Add isort configuration (profile=black, line_length=100) to pyproject.toml,
add isort pre-commit hook, and auto-sort imports across all Python source files.

Add [tool.black] config to pyproject.toml and Black hook to
.pre-commit-config.yaml (rev 26.3.1), then auto-format all Python
source and test files with line-length=100, target-version=py310.

Remove the 0.5mm query tolerance in favour of exact integer-unit matching
on all coordinate lookups (seed, label bridging, pin matching), mirroring
KiCad's own connectivity algorithm. Callers must supply exact wire endpoint
coordinates (e.g. from list_schematic_wires).

Update tool description and Python docstring to make clear that the
query point must be at a wire endpoint or junction — midpoints of
wire segments are not matched.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Shared-endpoint adjacency already connects all wires meeting at the same
point, making explicit junction handling a no-op duplicate.

Move wire connectivity logic from _handle_get_wire_connections into
commands/wire_connectivity.py. Use KiCad's internal integer unit system
(10,000 IU/mm) with exact coordinate matching instead of tolerance-based
float comparison, mirroring how KiCad itself determines connectivity.
Key improvements:
- Exact integer matching for wire endpoints (O(1) dict lookup vs O(n) grid scan)
- Junction support for T-connections
- Multi-unit symbol support (removed incorrect processed_refs dedup)
- Single public API: get_wire_connections()
