fix(new-project): display saved defaults before prompting to use them (#2333)

* fix(new-project): display saved defaults before prompting to use them

Replaces the blind Yes/No "Use saved defaults?" gate with a flow that
reads ~/.gsd/defaults.json first, displays all values in human-readable
form, then offers three options: use as-is, modify some settings, or
configure fresh.

The "modify some settings" path presents a multiSelect of only the
setting names (with current values shown), asks questions only for the
selected ones, and merges answers over the saved defaults — avoiding a
full re-walk when the user just wants to change one or two things.

Closes #2332

* fix(new-project): address CodeRabbit review comments

- Use canonical setting names (Research, Plan Check, Verifier) instead of
  "agent" suffix variants, matching Round 2 headers for clean mapping
- Add `text` language tag to fenced display blocks (MD040)
- Add TEXT_MODE fallback for multiSelect in "Modify some settings" path
  so non-Claude runtimes (Codex, Gemini) can use numbered list input

+Template for `.planning/phases/XX-name/{phase_num}-SPEC.md` — locks requirements before discuss-phase.
+
+**Purpose:** Capture WHAT a phase delivers and WHY, with enough precision that requirements are falsifiable. discuss-phase reads this file and focuses on HOW to implement (skipping "what/why" questions already answered here).
+
+**Key principle:** Every requirement must be falsifiable — you can write a test or check that proves it was met or not. Vague requirements like "improve performance" are not allowed.
+
+**Downstream consumers:**
+- `discuss-phase` — reads SPEC.md at startup; treats Requirements, Boundaries, and Acceptance Criteria as locked; skips "what/why" questions
+- `gsd-planner` — reads locked requirements to constrain plan scope
+- `gsd-verifier` — uses acceptance criteria as explicit pass/fail checks

+**Example 1: Feature addition (Post Feed)**
+
+```markdown
+# Phase 3: Post Feed — Specification
+
+**Created:** 2025-01-20
+**Ambiguity score:** 0.12
+**Requirements:** 4 locked
+
+## Goal
+
+Users can scroll through posts from accounts they follow, with new posts available after pull-to-refresh.
+
+## Background
+
+The database has a `posts` table and `follows` table. No feed query or feed UI exists today. The home screen shows a placeholder "Your feed will appear here." This phase builds the feed query, API endpoint, and the feed list component.
+
+## Requirements
+
+1. **Feed query**: Returns posts from followed accounts ordered by creation time, descending.
+   - Current: No feed query exists — `posts` table is queried directly only from profile pages
+   - Target: `GET /api/feed` returns paginated posts from followed accounts, newest first, max 20 per page
+   - Acceptance: Query returns correct posts for a user who follows 3 accounts with known post counts; cursor-based pagination advances correctly
+
+2. **Feed display**: Posts display in a scrollable card list.
+   - Current: Home screen shows static placeholder text
+   - Target: Home screen renders feed cards with author, timestamp, post content, and reaction count
+   - Acceptance: Feed renders without error for 0 posts (empty state shown), 1 post, and 20+ posts
+
+3. **Pull-to-refresh**: User can refresh the feed manually.
+   - Current: No refresh mechanism exists
+   - Target: Pull-down gesture triggers refetch; new posts appear at top of list
+   - Acceptance: After a new post is created in test, pull-to-refresh shows the new post without full app restart
+
+4. **New posts indicator**: When new posts arrive, a banner appears instead of auto-scrolling.
+   - Current: No such mechanism
+   - Target: "3 new posts" banner appears when refetch returns posts newer than the oldest visible post; tapping banner scrolls to top and shows new posts
+   - Acceptance: Banner appears for ≥1 new post, does not appear when no new posts, tap navigates to top
+
+## Boundaries
+
+**In scope:**
+- Feed query (backend) — posts from followed accounts, paginated
+- Feed list UI (frontend) — post cards with author, timestamp, content, reaction counts
+- Pull-to-refresh gesture
+- New posts indicator banner
+- Empty state when user follows no one or no posts exist
+
+**Out of scope:**
+- Creating posts — that is Phase 4
+- Reacting to posts — that is Phase 5
+- Following/unfollowing accounts — that is Phase 2 (already done)
+- Push notifications for new posts — separate backlog item
+
+## Constraints
+
+- Feed query must use cursor-based pagination (not offset) — the database has 500K+ posts and offset pagination is unacceptably slow beyond page 3
+- The feed card component must reuse the existing `<AvatarImage>` component from Phase 2
+
+## Acceptance Criteria
+
+- [ ] `GET /api/feed` returns posts only from followed accounts (not all posts)
+- [ ] `GET /api/feed` supports `cursor` parameter for pagination
+- [ ] Feed renders correctly at 0, 1, and 20+ posts
+- [ ] Pull-to-refresh triggers refetch
+- [ ] New posts indicator appears when posts newer than current view exist
+- [ ] Empty state renders when user follows no one

+
+```markdown
+# Phase 2: Backup Command — Specification
+
+**Created:** 2025-01-20
+**Ambiguity score:** 0.15
+**Requirements:** 3 locked
+
+## Goal
+
+A `gsd backup` CLI command creates a reproducible database snapshot that can be restored by `gsd restore` (a separate phase).
+
+## Background
+
+No backup tooling exists. The project uses PostgreSQL. Developers currently use `pg_dump` manually — there is no standardized process, no output naming convention, and no CI integration. Three incidents in the last quarter involved restoring from wrong or corrupt dumps.
+
+## Requirements
+
+1. **Backup creation**: CLI command executes a full database backup.
+   - Current: No `backup` subcommand exists in the CLI
+   - Target: `gsd backup` connects to the database (via `DATABASE_URL` env or `--db` flag), runs pg_dump, writes output to `./backups/YYYY-MM-DD_HH-MM-SS.dump`
+   - Acceptance: Running `gsd backup` on a test database creates a `.dump` file; running `pg_restore` on that file recreates the database without error
+
+2. **Network retry**: Transient network failures are retried automatically.
+   - Current: pg_dump fails immediately on network error
+   - Target: Backup retries up to 3 times with 5-second delay; 4th failure exits with code 1 and a message to stderr
+   - Acceptance: Simulating 2 sequential network failures causes 2 retries then success; simulating 4 failures causes exit code 1 and stderr message
+
+3. **Partial cleanup**: Failed backups do not leave corrupt files.
+   - Current: Manual pg_dump leaves partial files on failure
+   - Target: If backup fails after starting, the partial `.dump` file is deleted before exit
+   - Acceptance: After a simulated failure mid-dump, no `.dump` file exists in `./backups/`
+
+## Boundaries
+
+**In scope:**
+- `gsd backup` subcommand (full dump only)
+- Output to `./backups/` directory (created if missing)
+- Network retry (3 attempts)
+- Partial file cleanup on failure
+
+**Out of scope:**
+- `gsd restore` — that is Phase 3
+- Incremental backups — separate backlog item (full dump only for now)
+- S3 or remote storage — separate backlog item
+- Encryption — separate backlog item
+- Scheduled/cron backups — separate backlog item
+
+## Constraints
+
+- Must use `pg_dump` (not a custom query) — ensures compatibility with standard `pg_restore`
+- `--no-retry` flag must be available for CI use (fail fast, no retries)
+
+## Acceptance Criteria
+
+- [ ] `gsd backup` creates a `.dump` file in `./backups/YYYY-MM-DD_HH-MM-SS.dump` format
+- [ ] `gsd backup` uses `DATABASE_URL` env var or `--db` flag for connection
+- [ ] 3 retries on network failure, then exit code 1 with stderr message
+- [ ] `--no-retry` flag skips retries and fails immediately on first error
+- [ ] No partial `.dump` file left after a failed backup

+<guidelines>
+**Every requirement needs all three fields:**
+- Current: grounds the requirement in reality — what exists today?
+- Target: the concrete change — not "improve X" but "X becomes Y"
+- Acceptance: the falsifiable check — how does a verifier confirm this?
+
+**Ambiguity Report must reflect the actual interview.** If a dimension is below minimum, mark it ⚠ — the planner knows to treat it as an assumption rather than a locked requirement.
+
+**Interview Log is evidence of rigor.** Don't skip it. It shows that requirements came from discovery, not assumption.
+
+**Boundaries protect the phase from scope creep.** The out-of-scope list with reasoning is as important as the in-scope list. Future phases that touch adjacent areas can point to this SPEC.md to understand what was intentionally excluded.
+
+**SPEC.md is a one-way door for requirements.** discuss-phase will treat these as locked. If requirements change after SPEC.md is written, the user should update SPEC.md first, then re-run discuss-phase.
+
+**SPEC.md does NOT replace CONTEXT.md.** They serve different purposes:
+- SPEC.md: what the phase delivers (requirements, boundaries, acceptance criteria)
+- CONTEXT.md: how the phase will be implemented (decisions, patterns, tradeoffs)
+
+discuss-phase generates CONTEXT.md after reading SPEC.md.

+
+Parse JSON for: `phase_found`, `phase_dir`, `phase_number`, `phase_name`, `phase_slug`, `padded_phase`, `state_path`, `requirements_path`, `roadmap_path`, `planning_path`, `response_language`, `commit_docs`.
+
+**If `response_language` is set:** All user-facing text in this workflow MUST be in `{response_language}`. Technical terms, code, and file paths stay in English.
+
+**If `phase_found` is false:**
+```

+Use /gsd-progress to see available phases.
+```
+Exit.
+
+**Check for existing SPEC.md:**
+```bash
+ls ${phase_dir}/*-SPEC.md 2>/dev/null | grep -v AI-SPEC | head -1 || true
+```
+
+If SPEC.md already exists:
+
+**If `--auto`:** Auto-select "Update it". Log: `[auto] SPEC.md exists — updating.`
+
+**Otherwise:** Use AskUserQuestion:
+- header: "Spec"
+- question: "Phase [X] already has a SPEC.md. What do you want to do?"
+- options:
+  - "Update it" — Revise and re-score
+  - "View it" — Show current spec
+  - "Skip" — Exit (use existing spec as-is)
+
+If "View": Display SPEC.md, then offer Update/Skip.
+If "Skip": Exit with message: "Existing SPEC.md unchanged. Run /gsd-discuss-phase [X] to continue."
+If "Update": Load existing SPEC.md, continue to Step 3.
+
+## Step 2: Scout Codebase
+
+**Read these files before any questions:**
+- `{requirements_path}` — Project requirements
+- `{state_path}` — Decisions already made, current phase, blockers
+- ROADMAP.md phase entry — Phase description, goals, canonical refs
+
+**Grep the codebase** for code/files relevant to this phase goal. Look for:
+- Existing implementations of similar functionality
+- Integration points where new code will connect
+- Test coverage gaps relevant to the phase
+- Prior phase artifacts (SUMMARY.md, VERIFICATION.md) that inform current state
+
+**Synthesize current state** — the grounded baseline for the interview:
+- What exists today related to this phase
+- The gap between current state and the phase goal
+- The primary deliverable: what file/behavior/capability does NOT exist yet?
+
+Confirm your current state synthesis internally. Do not present it to the user yet — you'll use it to ask precise, grounded questions.

+
+Before questioning begins, score the phase's current ambiguity based only on what ROADMAP.md and REQUIREMENTS.md say:
+
+```
+Goal Clarity:       [score 0.0–1.0]
+Boundary Clarity:   [score 0.0–1.0]
+Constraint Clarity: [score 0.0–1.0]
+Acceptance Criteria:[score 0.0–1.0]
+
+Ambiguity: [score] ([calculate])
+```
+
+**If `--auto` and initial ambiguity already ≤ 0.20 with all minimums met:** Skip interview — derive SPEC.md directly from roadmap + requirements. Log: `[auto] Phase requirements are already sufficiently clear — generating SPEC.md from existing context.` Jump to Step 6.
+
+**Otherwise:** Continue to Step 4.
+
+## Step 4: Socratic Interview Loop
+
+**Max 6 rounds.** Each round: 2–3 questions max. End round after user responds.
+
+**Round selection by perspective:**
+- Round 1: Researcher
+- Round 2: Researcher + Simplifier
+- Round 3: Boundary Keeper
+- Round 4: Failure Analyst
+- Rounds 5–6: Seed Closer (focus on lowest-scoring dimensions)
+
+**After each round:**
+1. Update all 4 dimension scores from the user's answers
+2. Calculate new ambiguity score
+3. Display the updated scoring:
+
+```
+After round [N]:
+  Goal Clarity:       [score] (min 0.75) [✓ or ↑ needed]
+  Boundary Clarity:   [score] (min 0.70) [✓ or ↑ needed]
+  Constraint Clarity: [score] (min 0.65) [✓ or ↑ needed]
+  Acceptance Criteria:[score] (min 0.70) [✓ or ↑ needed]
+  Ambiguity: [score] (gate: ≤ 0.20)
+```
+
+**Gate check after each round:**
+
+If gate passes (ambiguity ≤ 0.20 AND all minimums met):
+
+**If `--auto`:** Jump to Step 6.
+
+**Otherwise:** AskUserQuestion:
+- header: "Spec Gate Passed"
+- question: "Ambiguity is [score] — requirements are clear enough to write SPEC.md. Proceed?"
+- options:
+  - "Yes — write SPEC.md" → Jump to Step 6
+  - "One more round" → Continue interview
+  - "Done talking — write it" → Jump to Step 6
+
+**If max rounds reached (6) and gate not passed:**
+
+**If `--auto`:** Write SPEC.md anyway — flag unresolved dimensions. Log: `[auto] Max rounds reached. Writing SPEC.md with [N] dimensions below minimum. Planner will need to treat these as assumptions.`
+
+**Otherwise:** AskUserQuestion:
+- header: "Max Rounds"
+- question: "After 6 rounds, ambiguity is [score]. [List dimensions still below minimum.] What would you like to do?"
+- options:
+  - "Write SPEC.md anyway — flag gaps" → Write SPEC.md, mark unresolved dimensions in Ambiguity Report
+  - "Keep talking" → Continue (no round limit from here)
+  - "Abandon" → Exit without writing
+
+**If `--auto` mode throughout:** Replace all AskUserQuestion calls above with Claude's recommended choice. Log decisions inline. Apply the same logic as `--auto` in discuss-phase.
+
+**Text mode (`workflow.text_mode: true` or `--text` flag):** Use plain-text numbered lists instead of AskUserQuestion TUI menus.
+
+## Step 5: (covered inline — ambiguity scoring is per-round)
+
+## Step 6: Generate SPEC.md
+
+Use the SPEC.md template from @~/.claude/get-shit-done/templates/spec.md.
+
+**Requirements for every requirement entry:**
+- One specific, testable statement
+- Current state (what exists now)
+- Target state (what it should become)
+- Acceptance criterion (how to verify it was met)
+
+**Vague requirements are rejected:**
+- ✗ "The system should be fast"
+- ✗ "Improve user experience"
+- ✓ "API endpoint responds in < 200ms at p95 under 100 concurrent requests"
+- ✓ "CLI command exits with code 1 and prints to stderr on invalid input"
+
+**Count requirements.** The display in discuss-phase reads: "Found SPEC.md — {N} requirements locked."
+
+**Boundaries must be explicit lists:**
+- "In scope" — what this phase produces
+- "Out of scope" — what it explicitly does NOT do (with brief reasoning)
+
+**Acceptance criteria must be pass/fail checkboxes** — no "should feel good" or "looks reasonable."
+
+**If any dimensions are below minimum**, mark them in the Ambiguity Report with: `⚠ Below minimum — planner must treat as assumption`.
+
+Write to: `{phase_dir}/{padded_phase}-SPEC.md`
+
+## Step 7: Commit
+
+```bash
+git add "${phase_dir}/${padded_phase}-SPEC.md"
+git commit -m "spec(phase-${phase_number}): add SPEC.md for ${phase_name} — ${requirement_count} requirements (#2213)"
+```
+
+If `commit_docs` is false: Skip commit. Note that SPEC.md was written but not committed.
+
+## Step 8: Wrap Up
+
+Display:
+
+```
+SPEC.md written — {N} requirements locked.
+
+  Phase {X}: {name}
+  Ambiguity: {final_score} (gate: ≤ 0.20)
+
+Next: /gsd-discuss-phase {X}
+  discuss-phase will detect SPEC.md and focus on implementation decisions only.
+```
+
+</process>
+
+<critical_rules>
+- Every requirement MUST have current state, target state, and acceptance criterion
+- Boundaries section is MANDATORY — cannot be empty
+- "In scope" and "Out of scope" must be explicit lists, not narrative prose
+- Acceptance criteria must be pass/fail — no subjective criteria
+- SPEC.md is NEVER written if the user selects "Abandon"
+- Do NOT ask about HOW to implement — that is discuss-phase territory
+- Scout the codebase BEFORE the first question — grounded questions only
+- Max 2–3 questions per round — do not frontload all questions at once
+</critical_rules>
+
+<success_criteria>
+- Codebase scouted and current state understood before questioning
+- All 4 dimensions scored after every round
+- Gate passed OR user explicitly chose to write despite gaps
+- SPEC.md contains only falsifiable requirements
+- Boundaries are explicit (in scope / out of scope with reasoning)
+- Acceptance criteria are pass/fail checkboxes
+- SPEC.md committed atomically (when commit_docs is true)
+- User directed to /gsd-discuss-phase as next step
+</success_criteria>
