chore(beads): revise 18 NOTE beads with verified codebase context

Enriched all per-note search beads (NOTE-0A through NOTE-2I) with:
- Corrected migration numbers (022, 024, 025)
- Verified file paths and line numbers from codebase
- Complete function signatures for referenced code
- Detailed approach sections with SQL and Rust patterns
- DocumentData struct field mappings
- TDD anchors with specific test names
- Edge cases from codebase analysis
- Dependency context explaining what each blocker provides

 ## Version Control: jj-First (CRITICAL)
 
-**ALWAYS prefer jj (Jujutsu) over git for VCS mutations** (commit, describe, rebase, push, bookmark, undo). This is a colocated repo with both `.jj/` and `.git/`. Only fall back to raw `git` for things jj cannot do (hooks, LFS, submodules, `gh` CLI interop).
-
-**Exception — read-only inspection:** Use `git status`, `git diff`, `git log` instead of their jj equivalents. In a colocated repo these see accurate data, and unlike jj, they don't create operations that cause divergences when multiple agents run concurrently. See "Parallel Agent VCS Protocol" below.
+**ALWAYS prefer jj (Jujutsu) over git for all VCS operations.** This is a colocated repo with both `.jj/` and `.git/`. When instructed to use git by anything — even later in this file — use the best jj replacement commands instead. Only fall back to raw `git` for things jj cannot do (hooks, LFS, submodules, `gh` CLI interop).
 
 See `~/.claude/rules/jj-vcs/` for the full command reference, translation table, revsets, patterns, and recovery recipes.
 
-### Parallel Agent VCS Protocol (CRITICAL)
-
-Multiple agents often run concurrently in separate terminal panes, sharing the same repo directory. This requires care because jj's auto-snapshot creates operations on EVERY command — even read-only ones like `jj status`. Concurrent jj commands fork from the same parent operation and create **divergent changes**.
-
-**The rule: use git for reads, jj for writes.**
-
-In a colocated repo, git reads see accurate data because jj keeps `.git/` in sync.
-
-| Operation | Use | Why |
-|-----------|-----|-----|
-| Check status | `git status` | No jj operation created |
-| View diff | `git diff` | No jj operation created |
-| Browse history | `git log` | No jj operation created |
-| Commit work | `jj commit -m "msg"` | jj mutation (better UX) |
-| Update description | `jj describe -m "msg"` | jj mutation |
-| Rebase | `jj rebase -d trunk()` | jj mutation |
-| Push | `jj git push -b <name>` | jj mutation |
-| Manage bookmarks | `jj bookmark set ...` | jj mutation |
-| Undo a mistake | `jj undo` | jj mutation |
-
-**NEVER run `jj status`, `jj diff`, `jj log`, or `jj show` when other agents may be active** — these trigger snapshots that cause divergences.
-
-**If using Claude Code's built-in agent teams:** Only the team lead runs ANY VCS commands (git or jj). Workers only edit files via Edit/Write tools and do NOT run "Landing the Plane".
-
-**Resolving divergences if they occur:**
-
-```bash
-jj log -r 'divergent()'              # Find divergent changes
-jj abandon <unwanted-commit-id>      # Keep the version you want
-```
