#!/usr/bin/env bash
# gstack-developer-profile — unified developer profile access and derivation.
#
# Supersedes bin/gstack-builder-profile. The old binary remains as a legacy
# shim that delegates to `gstack-developer-profile --read`.
#
# Subcommands:
#   --read              (default)  emit KEY: VALUE pairs in builder-profile format
#                                  for /office-hours compatibility.
#   --derive            recompute inferred dimensions from question events;
#                       write updated ~/.gstack/developer-profile.json.
#   --profile           emit the full profile as JSON (all fields).
#   --gap               emit declared-vs-inferred gap as JSON.
#   --trace <dim>       show events that contributed to a dimension.
#   --narrative         (v2 stub) output a coach bio paragraph.
#   --vibe              (v2 stub) output the one-word archetype.
#   --check-mismatch    detect meaningful gaps between declared and observed.
#   --migrate           migrate builder-profile.jsonl → developer-profile.json.
#                       Idempotent; archives the source file on success.
#   --log-session    append a session entry (from /office-hours) to
#                       sessions[] and update aggregates. Required fields:
#                       date, mode. Silent skip on invalid input.
#
# Profile file: ~/.gstack/developer-profile.json (unified schema — see
# docs/designs/PLAN_TUNING_V0.md). Event file: ~/.gstack/projects/{SLUG}/
# question-events.jsonl.
