Phase 5 complete — close jolt-c09

All seven Done criteria from §7:
1. ✅ Infinite-seq cases: 21/21 (0 hangs)
2. ✅ Conformance: 229/229 x3 (interpret/compile/self-host)
3. ✅ Specs: 32/32 files, 0 failures
4. ✅ clojure-test-suite: 3971 pass (up from 3926), 6 timeouts (down from 9)
5. ✅ Representation decision: Option B (hybrid), blast-radius measured
6. ✅ core-bench: TOTAL 2531 ms captured
7. ✅ bd close jolt-c09

Deferred to follow-up (not blocking):
- §6.3 laziness counter tests
- core-bench Phase-4 comparison
- Self-host + fixpoint verification

+# Agent Instructions
+
+This project uses **bd** (beads) for issue tracking. Run `bd prime` for full workflow context.
+
+> **Architecture in one line:** Issues live in a local Dolt database
+> (`.beads/dolt/`); cross-machine sync uses `bd dolt push/pull` (a
+> git-compatible protocol), stored under `refs/dolt/data` on your git
+> remote — separate from `refs/heads/*` where your code lives.
+> `.beads/issues.jsonl` is a passive export, not the wire protocol.
+>
+> See [SYNC_CONCEPTS.md](https://github.com/gastownhall/beads/blob/main/docs/SYNC_CONCEPTS.md)
+> for the one-screen overview and anti-patterns (don't treat JSONL as the
+> source of truth; don't `bd import` during normal operation; don't
+> reach for third-party Dolt hosting before trying the default).
+
+## Quick Reference
+
+```bash
+bd ready              # Find available work
+bd show <id>          # View issue details
+bd update <id> --claim  # Claim work atomically
+bd close <id>         # Complete work
+bd dolt push          # Push beads data to remote
+```
+
+## Non-Interactive Shell Commands
+
+**ALWAYS use non-interactive flags** with file operations to avoid hanging on confirmation prompts.
+
+Shell commands like `cp`, `mv`, and `rm` may be aliased to include `-i` (interactive) mode on some systems, causing the agent to hang indefinitely waiting for y/n input.
+
+**Use these forms instead:**
+```bash
+# Force overwrite without prompting
+cp -f source dest           # NOT: cp source dest
+mv -f source dest           # NOT: mv source dest
+rm -f file                  # NOT: rm file
+
+# For recursive operations
+rm -rf directory            # NOT: rm -r directory
+cp -rf source dest          # NOT: cp -r source dest
+```
+
+**Other commands that may prompt:**
+- `scp` - use `-o BatchMode=yes` for non-interactive
+- `ssh` - use `-o BatchMode=yes` to fail instead of prompting
+- `apt-get` - use `-y` flag
+- `brew` - use `HOMEBREW_NO_AUTO_UPDATE=1` env var

+## Beads Issue Tracker
+
+This project uses **bd (beads)** for issue tracking. Run `bd prime` to see full workflow context and commands.
+
+### Quick Reference
+
+```bash
+bd ready              # Find available work
+bd show <id>          # View issue details
+bd update <id> --claim  # Claim work
+bd close <id>         # Complete work
+```
+
+### Rules
+
+- Use `bd` for ALL task tracking — do NOT use TodoWrite, TaskCreate, or markdown TODO lists
+- Run `bd prime` for detailed command reference and session close protocol
+- Use `bd remember` for persistent knowledge — do NOT use MEMORY.md files
+
+**Architecture in one line:** issues live in a local Dolt DB; sync uses `refs/dolt/data` on your git remote; `.beads/issues.jsonl` is a passive export. See https://github.com/gastownhall/beads/blob/main/docs/SYNC_CONCEPTS.md for details and anti-patterns.
+
+## Session Completion
+
+**When ending a work session**, you MUST complete ALL steps below. Work is NOT complete until `git push` succeeds.
+
+**MANDATORY WORKFLOW:**
+
+1. **File issues for remaining work** - Create issues for anything that needs follow-up
+2. **Run quality gates** (if code changed) - Tests, linters, builds
+3. **Update issue status** - Close finished work, update in-progress items
+4. **PUSH TO REMOTE** - This is MANDATORY:
+   ```bash
+   git pull --rebase
+   git push
+   git status  # MUST show "up to date with origin"
+   ```
+5. **Clean up** - Clear stashes, prune remote branches
+6. **Verify** - All changes committed AND pushed
+7. **Hand off** - Provide context for next session
+
+**CRITICAL RULES:**
+- Work is NOT complete until `git push` succeeds
+- NEVER stop before pushing - that leaves work stranded locally
+- NEVER say "ready to push when you are" - YOU must push
+- If push fails, resolve and retry until it succeeds
