Critical bug fix: getNextID() was using alphabetical MAX instead of numerical MAX, causing "bd-9" to be treated as max when "bd-10" existed. This blocked all new issue creation after bd-10. Fixed by using SQL CAST to extract and compare numeric portions of IDs. This ensures bd-10 > bd-9 numerically, not alphabetically. Also completed comprehensive design for bd-9 (collision resolution): - Algorithm design with 7 phases (detection, scoring, remapping, etc.) - Created 7 child issues (bd-10, bd-12-17) breaking down implementation - Added design documents to .beads/ for future reference - Updated issues JSONL with new issues and dependencies Issues created: - bd-10: Export dependencies in JSONL - bd-12: Collision detection - bd-13: Reference scoring algorithm - bd-14: ID remapping with updates - bd-15: CLI flags and reporting - bd-16: Comprehensive tests - bd-17: Documentation updates - bd-18: Add design/notes fields to update command 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

BUG FOUND: getNextID() uses alphabetical MAX instead of numerical
Location
internal/storage/sqlite/sqlite.go:60-84, function getNextID()
The Bug
err := db.QueryRow("SELECT MAX(id) FROM issues").Scan(&maxID)
This uses alphabetical MAX on the text id column, not numerical MAX.
Impact
When you have bd-1 through bd-10:
- Alphabetical sort: bd-1, bd-10, bd-2, bd-3, ... bd-9
- MAX(id) returns "bd-9" (alphabetically last)
- nextID is calculated as 10
- Creating a new issue tries to use bd-10, which already exists
- Result: UNIQUE constraint failed
Reproduction
# After creating bd-1 through bd-10
./bd create "Test issue" -t task -p 1
# Error: failed to insert issue: UNIQUE constraint failed: issues.id
The Fix
Option 1: Cast to integer in SQL (BEST)
SELECT MAX(CAST(SUBSTR(id, INSTR(id, '-') + 1) AS INTEGER)) FROM issues WHERE id LIKE 'bd-%'
Option 2: Pad IDs with zeros
- Change ID format from "bd-10" to "bd-0010"
- Alphabetical and numerical order match
- Breaks existing IDs
Option 3: Query all IDs and find max in Go
- Less efficient but more flexible
- Works with any ID format
Recommended Solution
Option 1 with proper prefix handling:
func getNextID(db *sql.DB) int {
// Get prefix from config (default "bd")
var prefix string
err := db.QueryRow("SELECT value FROM config WHERE key = 'issue_prefix'").Scan(&prefix)
if err != nil || prefix == "" {
prefix = "bd"
}
// Find max numeric ID for this prefix
var maxNum sql.NullInt64
query := `
SELECT MAX(CAST(SUBSTR(id, LENGTH(?) + 2) AS INTEGER))
FROM issues
WHERE id LIKE ? || '-%'
`
err = db.QueryRow(query, prefix, prefix).Scan(&maxNum)
if err != nil || !maxNum.Valid {
return 1
}
return int(maxNum.Int64) + 1
}
Workaround for Now
Manually specify IDs when creating issues:
# This won't work because auto-ID fails:
./bd create "Title" -t task -p 1
# Workaround - manually calculate next ID:
./bd list | grep -oE 'bd-[0-9]+' | sed 's/bd-//' | sort -n | tail -1
# Then add 1 and create with explicit ID in code
Or fix the bug first before continuing!
Related to bd-9
This bug is EXACTLY the kind of distributed ID collision problem that bd-9 is designed to solve! But we should also fix the root cause.
Created Issue
Should create: "Fix getNextID() to use numerical MAX instead of alphabetical"
- Type: bug
- Priority: 0 (critical - blocks all new issue creation)
- Blocks: bd-9 (can't create child issues)
