Three root causes of the phantom-AskUserQuestion-hooks class, all in the
registration path:
- Bug A: the Conductor auto-opt-in upgraded PT_DECISION "prompt" -> "yes"
even when "prompt" was dev-setup's EXPLICIT --plan-tune-hooks=prompt pin,
so every new Conductor workspace installed hooks. PT_EXPLICIT (flag/env/
config-key-presence via `gstack-config has`) now gates the auto-opt-in to
the true silent fall-through.
- Bug B: hook commands were baked from $SOURCE_GSTACK_DIR (`pwd -P` of the
running tree — ephemeral for worktrees). Registration is now CANONICAL-ONLY
via _hook_command_path (${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/gstack);
missing canonical hook = skip + log, never a baked tree path. SessionStart
moves to schema-aware add-event under its identity source; whitespace paths
are quoted.
- Bug C: nothing ever pruned, and dead tagged entries blocked the
"already installed" guards forever. Setup now heals FIRST on every run
(prune-stale --repoint at the stable install), surfaces a one-line summary
only when something changed, surfaces the plan_tune_hooks:no-vs-live-hooks
contradiction, and --no-team tears down all three sources plus an identity
sweep for untagged strays.
dev-setup's no-mutation guarantee gains its stated repair exception (prune
dead / re-point existing, never ADD).
