feat: universal 'one decision per question' AskUserQuestion rule (v0.11.12.1) (#427)

* feat: universal "one decision per question" rule for AskUserQuestion

Add item 5 to the shared AskUserQuestion Format in generateAskUserFormat():
"NEVER combine multiple independent decisions into a single AskUserQuestion."
Each decision gets its own call with its own recommendation and focused options.
Batching multiple calls in rapid succession is fine and often preferred.

This promotes a rule already enforced by 3 plan-review skills (eng, ceo, design)
to the universal baseline, covering all 23+ skills via the shared preamble.

* chore: bump version and changelog (v0.11.12.1)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: add missing OPENAI_SHORT_DESCRIPTION_LIMIT constant

The merge from main dropped this constant (defined in resolvers/codex-helpers.ts
on main's modular version, but needed inline in our monolithic version). Caused
CI check-freshness to fail on `--host codex` generation.

* fix: add missing PLAN_COMPLETION_AUDIT resolvers to monolithic gen-skill-docs

The merge from main brought review/SKILL.md.tmpl with {{PLAN_COMPLETION_AUDIT_REVIEW}},
{{PLAN_COMPLETION_AUDIT_SHIP}}, and {{PLAN_VERIFICATION_EXEC}} placeholders, but the
local RESOLVERS map in the monolithic gen-skill-docs.ts didn't have entries for them.
Import the functions from scripts/resolvers/review.ts and register them.

 2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.
 3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.
 4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)`

 ## Completeness Principle — Boil the Lake
 
-AI makes completeness near-free. Always recommend the complete option over shortcuts — the delta is minutes with CC+gstack. A "lake" (100% coverage, all edge cases) is boilable; an "ocean" (full rewrite, multi-quarter migration) is not. Boil lakes, flag oceans.
+AI-assisted coding makes the marginal cost of completeness near-zero. When you present options:
 
-**Effort reference** — always show both scales:
+- If Option A is the complete implementation (full parity, all edge cases, 100% coverage) and Option B is a shortcut that saves modest effort — **always recommend A**. The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more.
+- **Lake vs. ocean:** A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope.
+- **When estimating effort**, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference:
 
 | Task type | Human team | CC+gstack | Compression |
 |-----------|-----------|-----------|-------------|
-| Boilerplate | 2 days | 15 min | ~100x |
-| Tests | 1 day | 15 min | ~50x |
-| Feature | 1 week | 30 min | ~30x |
-| Bug fix | 4 hours | 15 min | ~20x |
+| Boilerplate / scaffolding | 2 days | 15 min | ~100x |
+| Test writing | 1 day | 15 min | ~50x |
+| Feature implementation | 1 week | 30 min | ~30x |
+| Bug fix + regression test | 4 hours | 15 min | ~20x |
+| Architecture / design | 2 days | 4 hours | ~5x |
+| Research / exploration | 1 day | 3 hours | ~3x |
 
-Include `Completeness: X/10` for each option (10=all edge cases, 7=happy path, 3=shortcut).
+- This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds.
+
+**Anti-patterns — DON'T do this:**
+- BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.)
+- BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.)
+- BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.)
+- BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.")
+
+## Repo Ownership Mode — See Something, Say Something
+
+`REPO_MODE` from the preamble tells you who owns issues in this repo:
+
+- **`solo`** — One person does 80%+ of the work. They own everything. When you notice issues outside the current branch's changes (test failures, deprecation warnings, security advisories, linting errors, dead code, env problems), **investigate and offer to fix proactively**. The solo dev is the only person who will fix it. Default to action.
+- **`collaborative`** — Multiple active contributors. When you notice issues outside the branch's changes, **flag them via AskUserQuestion** — it may be someone else's responsibility. Default to asking, not fixing.
+- **`unknown`** — Treat as collaborative (safer default — ask before fixing).
+
+**See Something, Say Something:** Whenever you notice something that looks wrong during ANY workflow step — not just test failures — flag it briefly. One sentence: what you noticed and its impact. In solo mode, follow up with "Want me to fix it?" In collaborative mode, just flag it and move on.
+
+Never let a noticed issue silently pass. The whole point is proactive communication.
+
+## Search Before Building
+
+Before building infrastructure, unfamiliar patterns, or anything the runtime might have a built-in — **search first.** Read `~/.claude/skills/gstack/ETHOS.md` for the full philosophy.
+
+**Three layers of knowledge:**
+- **Layer 1** (tried and true — in distribution). Don't reinvent the wheel. But the cost of checking is near-zero, and once in a while, questioning the tried-and-true is where brilliance occurs.
+- **Layer 2** (new and popular — search for these). But scrutinize: humans are subject to mania. Search results are inputs to your thinking, not answers.
+- **Layer 3** (first principles — prize these above all). Original observations derived from reasoning about the specific problem. The most valuable of all.
+
+**Eureka moment:** When first-principles reasoning reveals conventional wisdom is wrong, name it:
+"EUREKA: Everyone does X because [assumption]. But [evidence] shows this is wrong. Y is better because [reasoning]."
+
+Log eureka moments:
+```bash
+jq -n --arg ts "$(date -u +%Y-%m-%dT%H:%M:%SZ)" --arg skill "SKILL_NAME" --arg branch "$(git branch --show-current 2>/dev/null)" --arg insight "ONE_LINE_SUMMARY" '{ts:$ts,skill:$skill,branch:$branch,insight:$insight}' >> ~/.gstack/analytics/eureka.jsonl 2>/dev/null || true
+```
+Replace SKILL_NAME and ONE_LINE_SUMMARY. Runs inline — don't stop the workflow.
+
+**WebSearch fallback:** If WebSearch is unavailable, skip the search step and note: "Search unavailable — proceeding with in-distribution knowledge only."
 
 ## Contributor Mode
 
-If `_CONTRIB` is `true`: you are in **contributor mode**. At the end of each major workflow step, rate your gstack experience 0-10. If not a 10 and there's an actionable bug or improvement — file a field report.
+If `_CONTRIB` is `true`: you are in **contributor mode**. You're a gstack user who also helps make it better.
 
-**File only:** gstack tooling bugs where the input was reasonable but gstack failed. **Skip:** user app bugs, network errors, auth failures on user's site.
+**At the end of each major workflow step** (not after every single command), reflect on the gstack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why. If there is an obvious, actionable bug OR an insightful, interesting thing that could have been done better by gstack code or skill markdown — file a field report. Maybe our contributor will help make us better!
+
+**Calibration — this is the bar:** For example, `$B js "await fetch(...)"` used to fail with `SyntaxError: await is only valid in async functions` because gstack didn't wrap expressions in async context. Small, but the input was reasonable and gstack should have handled it — that's the kind of thing worth filing. Things less consequential than this, ignore.
+
+**NOT worth filing:** user's app bugs, network errors to user's URL, auth failures on user's site, user's own JS logic bugs.
+
+**To file:** write `~/.gstack/contributor-logs/{slug}.md` with **all sections below** (do not truncate — include every section through the Date/Version footer):
