Garry Tan a6fb31726c v1.48.0.0 feat: AskUserQuestion split rule + runtime AUTO_DECIDE carve-out (#1740)
* feat(preamble): add "Handling 5+ options — split, never drop" rule

Agents repeatedly hit Conductor's 4-option AskUserQuestion cap and
silently drop one option to fit, shrinking the user's decision space.
This rule names the bug and gives two compliant shapes: batch into
≤4-groups (for coherent alternatives) or split into N sequential
per-option calls (for independent scope items, default).

Inline preamble subsection is ~15 lines (rule + buckets + pointer).
Full reference with worked examples, Hold/dependency semantics, and
final-summary validation lives in docs/askuserquestion-split.md.
The agent loads the docs file on demand when N>4.

Per-option call shape: D<N>.k header, ELI10, Recommendation, kind-note
(no completeness score — decision actions, not coverage), Include /
Defer / Cut / Hold buckets. Hold stops the chain immediately; the
final D<N>.final call validates dependencies and confirms the
assembled scope.

question_ids: <skill>-split-<option-slug> (kebab-case ASCII, ≤64
chars). Also fixes orphan "12. " prefix on the existing CJK rule.

Tier-2+ skills inherit via the existing resolver. SKILL.md regenerated
for all 41 affected skills + 3 golden fixtures. Net diff per SKILL.md:
~34 lines (vs ~110 for the full inline version).

6 tests pin the inline contract (4-option cap, buckets, D-numbering,
docs pointer, runtime AUTO_DECIDE gate reference, orphan 12 regression).

* feat(question-pref): runtime AUTO_DECIDE carve-out for *-split-* ids

Split chains (per-option AskUserQuestion calls emitted by the new
"Handling 5+ options" rule) must never be silently auto-approved
via /plan-tune preferences. The user's option set is sacred.

Layer 1 (mechanism): unique <skill>-split-<option-slug> ids prevent
cross-option preference leakage. Layer 2 (this commit): the runtime
checker `gstack-question-preference --check` detects any id matching
*-split-* and forces ASK_NORMALLY even when never-ask or
ask-only-for-one-way preferences exist for that exact id. An
explanatory note tells the user their preference was bypassed and why.

7 tests pin the carve-out: no-pref baseline, never-ask override,
explanatory note text, ask-only-for-one-way override, always-ask
(no note), non-split id containing "split" word (negative case for
regex specificity), multi-skill split id formats.

* test(e2e): split-overflow regression for /plan-ceo-review

Periodic-tier E2E test that catches the original failure mode the
user complained about: 5+ options for ONE decision must split into
N sequential AskUserQuestion calls, not drop one to fit Conductor's
4-option cap.

Fixture: 5 independent chat-platform integration candidates
(Slack/Discord/Teams/Telegram/Mattermost), each carrying its own
include/defer/cut decision. Floor = 4 review-phase AUQs (standard
[N-1] tolerance band). Pre-fix "drop to 4 + 1 dropped" fails this
floor.

Wired into test/helpers/touchfiles.ts: tier periodic, depends on
plan-ceo-review/**, the new preamble subsection, the question-pref
binary (for the carve-out), and the runner helper. touchfiles.test.ts
expected count bumped 21 → 22 to account for the new entry.

Cost: ~$0.30/run when EVALS_TIER=periodic. Skips silently otherwise.

* chore: post-merge regen + rebase size-budget baseline to v1.47.0.0

After merging origin/main (v1.45 → v1.47), three things needed cleanup:

1. spec/SKILL.md (main's new skill) regenerated to include our split-vs-drop
   preamble subsection — same mechanical regen as the other 41 tier-2+ skills.
2. Three golden ship fixtures refreshed to capture main's GSTACK_PLAN_MODE
   block + /spec routing entry + jargon-list.json refactor.
3. docs/skills.md — added /spec table row that main's PR (#1698/#1733) shipped
   without. Pre-existing failure on main; this PR catches and fixes.

Also rebased test/skill-size-budget.test.ts from v1.44.1 → v1.47.0.0 baseline.
Main's v1.46 (catalog tokens trim) + v1.47 (/spec skill) pushed the v1.44.1
anchor past the 5% ratchet to ×1.059 — pre-existing failure on main. This
PR captures a fresh parity-baseline-v1.47.0.0.json and re-anchors the test
there. Historical v1.44.1.json and v1.46.0.0.json retained in test/fixtures/
for reference. Our subsection contributes ~0.1% of the post-rebase corpus.
