feat: relationship closing — office-hours adapts to repeat users (v0.16.2.0) (#937)

* fix: sync package.json version with VERSION file package.json was 0.15.15.0 while VERSION was 0.15.16.0, causing gen-skill-docs freshness check test failures. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add builder profile helper for office-hours relationship closing New bin/gstack-builder-profile reads ~/.gstack/builder-profile.jsonl and outputs structured summary (tier, signals, resources, topics). Single source of truth for all closing state — no separate config keys or logs. Uses bun-based JSONL parsing pattern from gstack-learnings-search. Graceful fallback to introduction tier if bun unavailable or file missing. 26 unit tests covering tier computation, signal accumulation, cross-project detection, nudge eligibility, resource dedup, and malformed JSONL handling. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: relationship closing — office-hours adapts to repeat users The office-hours closing now deepens over time instead of repeating the same YC plea every session. Four tiers based on session count: - Introduction (session 1): full YC plea + founder resources - Welcome Back (sessions 2-3): lead with recognition, skip plea - Regular (sessions 4-7): arc-level callbacks, signal visibility, builder-to-founder nudge, auto-generated journey summary - Inner Circle (sessions 8+): the data speaks Key design decisions (from CEO + Eng + Codex + DX reviews): - Single source of truth: one builder-profile.jsonl, no split-brain state - Lead with recognition on repeat visits (DX: magical moment hits immediately) - Narrative arc journey summary, not data tables - Tone examples per tier to prevent generic AI voice - Global resource dedup (low-sensitivity video watch history) - Migration merges per-project resource logs into builder profile Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.16.2.0) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

 # Changelog
 ## [0.16.2.0] - 2026-04-09
 ### Added
 - **Office hours now remembers you.** The closing experience adapts based on how many sessions you've done. First time: full YC plea and founder resources. Sessions 2-3: "Welcome back. Last time you were working on [your project]. How's it going?" Sessions 4-7: arc-level callbacks across your whole journey, accumulated signal visibility, and an auto-generated Builder Journey narrative. Sessions 8+: the data speaks for itself.
 - **Builder profile** tracks your office hours journey in a single append-only session log. Signals, design docs, assignments, topics, and resources shown, all in one file. No split-brain state, no separate config keys.
 - **Builder-to-founder nudge** for repeat builder-mode users who accumulate founder signals. Evidence-gated: only triggers when you've shown 5+ signals across 3+ builder sessions. Not a pitch. An observation.
 - **Journey-matched resources.** Instead of category-matching from the static pool, resources now match your accumulated session context. "You've been iterating on a fintech idea for 3 sessions... Tom Blomfield built Monzo from exactly this kind of persistence."
 - **Builder Journey Summary** auto-generates at session 5+ and opens in your browser. A narrative arc of your journey, not a data table. Written in second person, referencing specific things you said across sessions.
 - **Global resource dedup.** Resource links now dedup globally (not per-project), so switching repos doesn't reset your watch history. Each link shows only once, ever.
 ### Fixed
 - package.json version now stays in sync with VERSION file.

-**Dedup check — read before selecting:**
+### If TIER = welcome_back (sessions 2-3)
 Lead with recognition. The magical moment is immediate.
 Read LAST_ASSIGNMENT and CROSS_PROJECT from the profile output.
 If CROSS_PROJECT is false (same project as last time):
 "Welcome back. Last time you were working on [LAST_ASSIGNMENT from profile]. How's it going?"
 If CROSS_PROJECT is true (different project):
 "Welcome back. Last time we talked about [LAST_PROJECT from profile]. Still on that, or onto something new?"
 Then: "No pitch this time. You already know about YC. Let's talk about your work."
 **Tone examples (prevent generic AI voice):**
 - GOOD: "Welcome back. Last time you were designing that task manager for ops teams. Still on that?"
 - BAD: "Welcome back to your second office hours session. I'd like to check in on your progress."
 - GOOD: "No pitch this time. You already know about YC. Let's talk about your work."
 - BAD: "Since you've already seen the YC information, we'll skip that section today."
 After the check-in, deliver signal reflection (same anti-slop rules as introduction tier).
 Then: Design doc trajectory. Read DESIGN_TITLES from the profile.
 "Your first design was [first title]. Now you're on [latest title]."
 Then proceed to Founder Resources below.
 ---
 ### If TIER = regular (sessions 4-7)
 Lead with recognition and session count.
 "Welcome back. This is session [SESSION_COUNT]. Last time: [LAST_ASSIGNMENT]. How'd it go?"
 **Tone examples:**
 - GOOD: "You've been at this for 5 sessions now. Your designs keep getting sharper. Let me show you what I've noticed."
 - BAD: "Based on my analysis of your 5 sessions, I've identified several positive trends in your development."
 After the check-in, deliver arc-level signal reflection. Reference patterns ACROSS sessions, not just this one.
 Example: "In session 1, you described users as 'small businesses.' By now you're saying 'Sarah at Acme Corp.' That specificity shift is a signal."
 Design trajectory with interpretation:
 "Your first design was broad. Your latest narrows to a specific wedge, that's the PMF pattern."
 **Accumulated signal visibility:** Read ACCUMULATED_SIGNALS from the profile.
 "Across your sessions, I've noticed: you've named specific users [N] times, pushed back on premises [N] times, shown domain expertise in [topics]. These patterns mean something."
 **Builder-to-founder nudge** (only if NUDGE_ELIGIBLE is true from profile):
 "You started this as a side project. But you've named specific users, pushed back when challenged, and your designs keep getting sharper each time. I don't think this is a side project anymore. Have you thought about whether this could be a company?"
 This must feel earned, not broadcast. If the evidence doesn't support it, skip entirely.
 **Builder Journey Summary** (session 5+): Auto-generate `~/.gstack/builder-journey.md`
 with a narrative arc (not a data table). The arc tells the STORY of their journey in
 second person, referencing specific things they said across sessions. Then open it:
 ```bash

 ### If TIER = inner_circle (sessions 8+)
 "You've done [SESSION_COUNT] sessions. You've iterated [DESIGN_COUNT] designs. Most people who show this pattern end up shipping."
 The data speaks. No pitch needed.

 ### Founder Resources (all tiers)
 Share 2-3 resources from the pool below. For repeat users, resources compound by matching
 to accumulated session context, not just this session's category.
 **Dedup check:** Read `RESOURCES_SHOWN` from the builder profile output above.
 If `RESOURCES_SHOWN_COUNT` is 34 or more, skip this section entirely (all resources exhausted).
 Otherwise, avoid selecting any URL that appears in the RESOURCES_SHOWN list.

 **Beat 1: Signal Reflection + Golden Age**
 One paragraph that weaves specific session callbacks with the golden age framing. Reference actual things the user said, quote their words back to them.
 **Anti-slop rule, show, don't tell:**
 - GOOD: "You didn't say 'small businesses,' you said 'Sarah, the ops manager at a 50-person logistics company.' That specificity is rare."
 - BAD: "You showed great specificity in identifying your target user."
 - GOOD: "You pushed back when I challenged premise #2. Most people just agree."
 - BAD: "You demonstrated conviction and independent thinking."
-Example: "The way you think about this problem — [specific callback] — that's founder thinking. A year ago, building what you just designed would have taken a team of 5 engineers three months. Today you can build it this weekend with Claude Code. The engineering barrier is gone. What remains is taste — and you just demonstrated that."

 > A personal note from me, Garry Tan, the creator of GStack: what you just experienced is about 10% of the value you'd get working with a YC partner at Y Combinator. The other 90% is the network of founders who've done it before you, the batch pressure that makes you ship faster than you thought possible, weekly dinners where people who built billion-dollar companies tell you exactly what to do next, and a partner who knows your business deeply and pushes you every single week.
 >
 > GStack thinks you are among the top people who could do this.
 Then use AskUserQuestion: "Would you consider applying to Y Combinator?"
 - If yes: run `open https://ycombinator.com/apply?ref=gstack` and say: "Bring this design doc to your YC interview. It's better than most pitch decks."

-### Beat 3.5: Founder Resources
+Then proceed to Founder Resources below.
-After the YC plea, share 2-3 resources from the pool below. This keeps the closing fresh for repeat users and gives them something concrete to engage with beyond the application link.
+---
-**Dedup check — read before selecting:**
+### If TIER = welcome_back (sessions 2-3)
 Lead with recognition. The magical moment is immediate.
 Read LAST_ASSIGNMENT and CROSS_PROJECT from the profile output.
 If CROSS_PROJECT is false (same project as last time):
 "Welcome back. Last time you were working on [LAST_ASSIGNMENT from profile]. How's it going?"
 If CROSS_PROJECT is true (different project):
 "Welcome back. Last time we talked about [LAST_PROJECT from profile]. Still on that, or onto something new?"
 Then: "No pitch this time. You already know about YC. Let's talk about your work."
 **Tone examples (prevent generic AI voice):**
 - GOOD: "Welcome back. Last time you were designing that task manager for ops teams. Still on that?"
 - BAD: "Welcome back to your second office hours session. I'd like to check in on your progress."
 - GOOD: "No pitch this time. You already know about YC. Let's talk about your work."
 - BAD: "Since you've already seen the YC information, we'll skip that section today."
 After the check-in, deliver signal reflection (same anti-slop rules as introduction tier).
 Then: Design doc trajectory. Read DESIGN_TITLES from the profile.
 "Your first design was [first title]. Now you're on [latest title]."
 Then proceed to Founder Resources below.
 ---
 ### If TIER = regular (sessions 4-7)
 Lead with recognition and session count.
 "Welcome back. This is session [SESSION_COUNT]. Last time: [LAST_ASSIGNMENT]. How'd it go?"
 **Tone examples:**
 - GOOD: "You've been at this for 5 sessions now. Your designs keep getting sharper. Let me show you what I've noticed."
 - BAD: "Based on my analysis of your 5 sessions, I've identified several positive trends in your development."
 After the check-in, deliver arc-level signal reflection. Reference patterns ACROSS sessions, not just this one.
 Example: "In session 1, you described users as 'small businesses.' By now you're saying 'Sarah at Acme Corp.' That specificity shift is a signal."
 Design trajectory with interpretation:
 "Your first design was broad. Your latest narrows to a specific wedge, that's the PMF pattern."
 **Accumulated signal visibility:** Read ACCUMULATED_SIGNALS from the profile.
 "Across your sessions, I've noticed: you've named specific users [N] times, pushed back on premises [N] times, shown domain expertise in [topics]. These patterns mean something."
 **Builder-to-founder nudge** (only if NUDGE_ELIGIBLE is true from profile):
 "You started this as a side project. But you've named specific users, pushed back when challenged, and your designs keep getting sharper each time. I don't think this is a side project anymore. Have you thought about whether this could be a company?"
 This must feel earned, not broadcast. If the evidence doesn't support it, skip entirely.
 **Builder Journey Summary** (session 5+): Auto-generate `~/.gstack/builder-journey.md`
 with a narrative arc (not a data table). The arc tells the STORY of their journey in
 second person, referencing specific things they said across sessions. Then open it:
 ```bash
-eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" 2>/dev/null || true
+open "${GSTACK_HOME:-$HOME/.gstack}/builder-journey.md"
 SHOWN_LOG="${GSTACK_HOME:-$HOME/.gstack}/projects/${SLUG:-unknown}/resources-shown.jsonl"
 [ -f "$SHOWN_LOG" ] && cat "$SHOWN_LOG" || echo "NO_PRIOR_RESOURCES"
 ```
-If prior resources exist, avoid selecting any URL that appears in the log. This ensures repeat users always see fresh content.
+
 Then proceed to Founder Resources below.
 ---
 ### If TIER = inner_circle (sessions 8+)
 "You've done [SESSION_COUNT] sessions. You've iterated [DESIGN_COUNT] designs. Most people who show this pattern end up shipping."
 The data speaks. No pitch needed.
 Full accumulated signal summary from the profile.
 Auto-generate updated `~/.gstack/builder-journey.md` with narrative arc. Open it.
 Then proceed to Founder Resources below.
 ---
 ### Founder Resources (all tiers)
 Share 2-3 resources from the pool below. For repeat users, resources compound by matching
 to accumulated session context, not just this session's category.
 **Dedup check:** Read `RESOURCES_SHOWN` from the builder profile output above.
 If `RESOURCES_SHOWN_COUNT` is 34 or more, skip this section entirely (all resources exhausted).
 Otherwise, avoid selecting any URL that appears in the RESOURCES_SHOWN list.
 **Selection rules:**
 - Pick 2-3 resources. Mix categories — never 3 of the same type.
