Garry TanandClaude Opus 4.7 32242276dc cli: gbrain calibration + get_calibration_profile MCP op (T7)
Public-facing read surface for the v0.36.0.0 calibration wave. CLI prints
the active calibration profile; MCP op exposes the same data path for
agents. Mirror of the v0.29 salience/anomalies shape (pure data fn + JSON
formatter + human formatter + thin CLI dispatch).

CLI: `gbrain calibration`
  Flags:
    --holder <id>         specific holder (default 'garry')
    --json                machine output for piping
    --regenerate          run calibration_profile phase now
    --undo-wave <ver>     [placeholder — wires in Lane D / T17]
    ab-report             [placeholder — wires in Lane D / T18]

  Human output:
    Calibration profile — holder: garry, source: default
    Generated: <local timestamp>
    [Note: built on 60% graded — partial completion this cycle.]   (when grade_completion < 0.9)
    [Note: voice gate fell back to template (2 attempts).]         (when voice_gate_passed=false)

    Resolved: 12 takes
    Brier:    0.210 (lower is better)
    Accuracy: 60.0%
    Partial:  10.0%

    Pattern statements:
      • You called early-stage tactics well — 8 of 10 held up.

    Active bias tags: over-confident-geography

  Cold-brain fallback message names the exact dream command to run.

MCP: `get_calibration_profile` (scope: read)
  Param: holder?: string (defaults to 'garry')
  Returns: latest CalibrationProfileRow | null

  Source-scoping via sourceScopeOpts(ctx): scalar source-bound clients see
  only their source; federated_read scopes see the union of allowed sources;
  no source filter when neither is set (CLI default path).

  Throws GBrainError('INVALID_HOLDER') on empty/non-string holder so
  remote callers get a structured error instead of a SQL-shape failure.

Architecture:
  getLatestProfile is the pure data fn — engine + opts → CalibrationProfileRow | null.
  Reused by both the CLI and the MCP op. Source-scoped via the standard
  v0.34.1 spread pattern (scalar sourceId vs sourceIds array).

  formatProfileText is pure — null → cold-brain message, populated → full
  printout. Annotates partial-grade rows and voice-gate-fallback rows so
  the operator sees data-quality status inline.

  parseArgs is exported via __testing for unit coverage. Sub-command
  ('ab-report') vs flag distinction is intentional — keeps the surface
  parallel with `gbrain eval cross-modal` etc.

Tests: 21 cases.
  parseArgs (6 cases): empty, --holder, --json, --regenerate, --undo-wave, ab-report.
  getLatestProfile (5 cases): happy, null, scalar source scope, federated array
    scope, no-source-filter default.
  formatProfileText (5 cases): cold-brain, happy, partial-grade note, voice-fallback
    note, published-to-mounts note.
  getCalibrationProfileOp (5 cases): default holder, scalar source scope,
    federated scope union, returns-null-on-unknown-holder, throws on empty holder.

Lane D follow-ups: --undo-wave (T17) and ab-report (T18) print a clear
"lands in Lane D" stderr line + exit 2; the surfaces exist for early
testers, the implementations land next.
