Navigation Hardening Pass

What this skill does

This skill packages the navigation/runtime credibility workflow from the maintainer handbook into a repeatable implementation sequence.

Best use cases

waypoint progress advancing too optimistically
pause, abort, interrupt, or fault paths not stopping cleanly
obstacle hold or lost-position behavior uncertainty
mission execution depending on navigation behavior without enough feedback evidence

Procedure

Start with a navigation feedback audit.
- trace where the system assumes movement succeeded
- identify where encoder, GPS, controller, or other feedback actually confirms motion
- list state transitions that can advance without enough evidence
Harden stop and fault behavior.
- ensure controller failures, obstacle holds, interrupts, and aborts fail closed
- verify pause and abort paths route through a clean stop path
Tighten regression coverage.
- prioritize service-level and contract-level tests around interrupted waypoint traversal, lost position, obstacle gating, and command-delivery failures
Re-run the focused navigation and mission validation slice.
Update maintainer docs if subsystem maturity, behavior, or limitations changed materially.

Working rules

prefer concrete field-feedback evidence over optimistic state updates
keep behavior deterministic when control or position confidence drops
do not broaden scope into unrelated autonomy work during a hardening pass
if navigation service signatures or public helpers changed, sync docs/code_structure_overview.md

Completion checks

a defect list or risk list exists before edits begin
stop and interruption semantics are explicit after the change
regression coverage matches the specific failure mode addressed
final notes distinguish hardened behavior from remaining field limitations

maintainer-doc-sync

acredsfan/lawnberry_pi

Keep LawnBerry Pi maintainer documentation synchronized with implementation. Use when runtime behavior, supported hardware scope, subsystem maturity, immediate focus, two-week plan, release notes, or callable interfaces have changed and docs must be updated in the same pass.

acredsfan/lawnberry_pi

Use when returning to LawnBerry Pi after time away, starting substantial maintenance, or needing a fast project re-entry workflow. Covers docs to read first, runtime ports, hardware baseline, simulation vs hardware mode, important files by task, and validation planning.
