v0.12.0 — run/walk-aware stream analytics, gear tracking, CI estimation

[0.12.0] — 2026-06-11

Breaking Changes

• Removed include_legacy param from get_weekly_summary and get_current_pmc.
  The lbss_legacy key is no longer emitted in tool output.
  To compare against an older or alternative LBSS field ad-hoc, pass lbss_field per-call
  (e.g. lbss_field: "StrydLBSSmod").
• Removed LBSS_FIELD_LEGACY env var. The server no longer reads this variable;
  any existing .env entry is silently ignored (Zod unknown-key strip).
  Remove the line from your .env and MCPB user_config if present.

New Features

• avg_stride_length_m per split and overall in get_activity_streams_summary.
  Derived as velocity / (cadence_stream × 2 / 60); uses the run cadence stream (rpm,
  one-foot), verified against Intervals.icu average_cadence.

• EXTRA_STREAM_FIELDS env var — comma-separated Intervals custom stream codes
  (e.g. StrydLSS,StrydTemp,StrydHumidity) fetched and surfaced as extras per split
  and overall in get_activity_streams_summary. Requires custom stream mapping on an
  Intervals.icu activity page (CHARTS → CUSTOM STREAMS → ADD STREAM). Backward-compatible:
  extras key is absent when not configured.

• run_fraction + extras_run in get_activity_streams_summary.
  run_fraction: share of valid samples at or above the run-gate cadence threshold
  (default 70 rpm = 140 spm), per split and overall.
  extras_run: extras averages restricted to running samples only, for separating
  per-stride metric change from walk-mix dilution (e.g. StrydLSS stiffness drift vs.
  gait-mix change in ultra-distance races).
  Configurable via run_gate_cadence_rpm param (range 40–120).
  Both keys absent when cadence stream is not present (backward-compatible).

• run_gate_cadence_rpm param in get_activity_streams_summary (default 70,
  range 40–120). Echoed in data_quality.run_gate_cadence_rpm.

Internal

• LBSS_FIELD_LEGACY / lbssFieldLegacy removed from config, tool registry, and
  MCPB manifest.json user_config.
• .env.example reorganized into Activity custom fields and Streams sections.
• manifest.json user_config: removed lbss_field_legacy, added extra_stream_fields.
