Phase 3: Structured Storage & Priority Management - Implementation Summary

Overview

Implemented SQLite-based structured storage for CANARY tokens with advanced metadata tracking, priority management, and state checkpointing.

Problem Solved

Before Phase 3: - Tokens existed only in source code comments - No central index or queryable database - No priority ordering or dependency tracking - No historical snapshots of project state - Limited metadata (only basic fields)

After Phase 3: - SQLite database for structured token storage - Priority-driven development (1=highest, 10=lowest) - Keyword search and advanced filtering - Git integration (commit hash, branch tracking) - State checkpoints for progress tracking - Relationship tracking (depends_on, blocks, related_to) - Phase and spec lifecycle management

Implementation

1. Storage Schema (CBIN-123)

File: internal/storage/schema.sql

Tables: - tokens - Extended token metadata with 40+ fields - checkpoints - State snapshots with summary statistics - search_history - Search analytics (future use)

Key indexes: - idx_tokens_priority - Fast priority ordering - idx_tokens_status - Filter by status - idx_tokens_keywords - Keyword search - idx_tokens_phase - Phase filtering - idx_tokens_aspect - Aspect filtering - idx_tokens_spec_status - Spec lifecycle filtering

Extended fields:

-- Priority and organization
priority INTEGER DEFAULT 5,  -- 1 (highest) to 10 (lowest)
phase TEXT,                   -- Phase0, Phase1, Phase2, Phase3
keywords TEXT,                -- Comma-separated tags
spec_status TEXT,             -- draft, approved, in-progress, completed, archived

-- Lifecycle dates
created_at TEXT,
updated_at TEXT NOT NULL,
started_at TEXT,
completed_at TEXT,

-- Git integration
commit_hash TEXT,
branch TEXT,

-- Relationships
depends_on TEXT,  -- Comma-separated REQ-IDs
blocks TEXT,      -- Comma-separated REQ-IDs
related_to TEXT,  -- Comma-separated REQ-IDs

2. Storage Layer (CBIN-123)

File: internal/storage/storage.go

Core types:

type Token struct {
    ID          int
    ReqID       string
    Feature     string
    Aspect      string
    Status      string
    FilePath    string
    LineNumber  int
    Priority    int
    Phase       string
    Keywords    string
    SpecStatus  string
    // ... 30+ fields total
}

type Checkpoint struct {
    ID           int
    Name         string
    CommitHash   string
    TotalTokens  int
    StubCount    int
    ImplCount    int
    TestedCount  int
    BenchedCount int
    SnapshotJSON string
}

type DB struct {
    conn *sql.DB
    path string
}

Methods: - Open(dbPath string) (*DB, error) - Open/create database - UpsertToken(token *Token) error - Insert or update token - GetTokensByReqID(reqID string) ([]*Token, error) - Get all tokens for requirement - ListTokens(filters map[string]string, orderBy string, limit int) ([]*Token, error) - List with filtering - SearchTokens(keywords string) ([]*Token, error) - Keyword search - UpdatePriority(reqID, feature string, priority int) error - Update priority - UpdateSpecStatus(reqID, specStatus string) error - Update spec status - CreateCheckpoint(name, description, commitHash, snapshotJSON string) error - Create snapshot - GetCheckpoints() ([]*Checkpoint, error) - Retrieve checkpoints

3. CLI Commands

canary index (CBIN-124)

Purpose: Build/rebuild SQLite database from codebase

Features: - Scans codebase with grep for all CANARY tokens - Extracts all fields including extended metadata - Captures git commit hash and branch - Stores in .canary/canary.db by default - Reports statistics on completion

Usage:

canary index                        # Index current directory
canary index --root /path/to/code   # Index specific directory
canary index --db custom.db         # Use custom database path

Output:

Indexing CANARY tokens from: .

✅ Indexed 278 CANARY tokens
Database: .canary/canary.db
Commit: b24feb75
Branch: main

canary list (CBIN-125)

Purpose: List tokens with filtering and priority ordering

Features: - Filter by status, aspect, phase, owner, spec_status - Custom ordering (default: priority ASC, updated_at DESC) - Limit results - JSON output option

Flags: - --status - Filter by status (STUB, IMPL, TESTED, BENCHED) - --aspect - Filter by aspect (API, CLI, Engine, etc.) - --phase - Filter by phase (Phase0, Phase1, Phase2, Phase3) - --owner - Filter by owner - --spec-status - Filter by spec status (draft, approved, etc.) - --order-by - Custom SQL ORDER BY clause - --limit - Maximum number of results - --json - Output as JSON

Usage:

canary list --status STUB --limit 10
canary list --phase Phase1 --owner backend
canary list --order-by "priority ASC, updated_at DESC"
canary list --json > tokens.json

Output:

Found 5 tokens:

📌 CBIN-123 - TokenStorage
   Status: IMPL | Aspect: Storage | Priority: 1
   Location: ./internal/storage/storage.go:1
   Owner: canary

📌 CBIN-124 - IndexCmd
   Status: IMPL | Aspect: CLI | Priority: 5
   Location: ./cmd/canary/main.go:828
   ...

canary search (CBIN-126)

Purpose: Search tokens by keywords

Features: - Searches in feature names, requirement IDs, and keyword tags - Case-insensitive LIKE queries - JSON output option

Usage:

canary search "authentication"
canary search "oauth jwt"
canary search "storage" --json

Output:

Search results for 'storage' (2 tokens):

📌 CBIN-123 - TokenStorage
   Status: IMPL | Priority: 1 | ./internal/storage/storage.go:1

📌 CBIN-123 - TokenStorage
   Status: IMPL | Priority: 1 | ./internal/storage/schema.sql:1

canary prioritize (CBIN-127)

Purpose: Update token priority

Features: - Set priority 1 (highest) to 10 (lowest) - Affects ordering in list and search results - Validates priority range

Usage:

canary prioritize CBIN-123 TokenStorage 1
canary prioritize CBIN-001 JWTValidation 3

Output:

✅ Updated priority for CBIN-123/TokenStorage to 1

canary checkpoint (CBIN-128)

Purpose: Create state snapshot

Features: - Captures all tokens as JSON snapshot - Records counts by status - Stores git commit hash - Timestamped for historical tracking

Usage:

canary checkpoint "phase1-complete" "All Phase 1 features implemented"
canary checkpoint "v1.0.0" "Release 1.0.0 snapshot"

Output:

✅ Created checkpoint: phase3-storage
Commit: b24feb75
Tokens: 278

Extended Token Format

Tokens can now include these optional fields:

CANARY: REQ=CBIN-XXX; FEATURE="Name"; ASPECT=API; STATUS=IMPL; PRIORITY=1; PHASE=Phase1; KEYWORDS="auth,security"; SPEC_STATUS=approved; DEPENDS_ON=CBIN-001,CBIN-002; BLOCKS=CBIN-005; RELATED_TO=CBIN-010; TEST=TestName; BENCH=BenchName; OWNER=team; UPDATED=2025-10-16

New fields: - PRIORITY - 1 (highest) to 10 (lowest), default 5 - PHASE - Phase0, Phase1, Phase2, Phase3 - KEYWORDS - Comma-separated tags for search - SPEC_STATUS - draft, approved, in-progress, completed, archived - DEPENDS_ON - Comma-separated REQ-IDs this depends on - BLOCKS - Comma-separated REQ-IDs this blocks - RELATED_TO - Related requirement IDs - CREATED - Creation date (YYYY-MM-DD) - STARTED - Start date (YYYY-MM-DD) - COMPLETED - Completion date (YYYY-MM-DD)

Automatic fields (captured during index): - commit_hash - Git commit hash at index time - branch - Git branch at index time - indexed_at - Timestamp when indexed (RFC3339)

Testing

Manual testing:

1. Index command: bash mkdir -p .canary && ./bin/canary index # ✅ Indexed 278 tokens

2. List command: ```bash ./bin/canary list --limit 5 # ✅ Shows 5 tokens with priority ordering

./bin/canary list --status IMPL --limit 3 # ✅ Filters to IMPL status only ```

1. Search command: bash ./bin/canary search "storage" # ✅ Found 2 TokenStorage tokens

2. Prioritize command: ```bash ./bin/canary prioritize CBIN-123 TokenStorage 1 # ✅ Updated priority to 1

./bin/canary search "TokenStorage" # ✅ Shows priority 1 ```

1. Checkpoint command: bash ./bin/canary checkpoint "phase3-storage" "Added storage features" # ✅ Created checkpoint with 278 tokens

All tests passing: - Database creation successful - Token indexing works across file types - Filtering and searching accurate - Priority updates persist - Checkpoints capture full state - Git integration captures commit/branch

Use Cases

1. Priority-Driven Development

# Index codebase
canary index

# Find highest priority STUB features
canary list --status STUB --order-by "priority ASC" --limit 5

# Work on them in order
canary implement CBIN-001 --feature HighPriorityFeature

# Mark as IMPL when done, re-prioritize others

2. Phase-Based Planning

# List Phase1 features
canary list --phase Phase1

# Find what's blocking Phase2
canary search "Phase2" | grep "DEPENDS_ON"

# Complete Phase1, checkpoint it
canary checkpoint "phase1-complete"

3. Keyword Organization

# Find all auth-related features
canary search "auth"
canary search "security"

# Find all database features
canary search "database storage"

4. Progress Tracking

# Create checkpoints at milestones
canary checkpoint "sprint-1" "Sprint 1 complete"
canary checkpoint "sprint-2" "Sprint 2 complete"

# Compare progress (via checkpoint table)
sqlite3 .canary/canary.db "SELECT name, total_tokens, impl_count, tested_count FROM checkpoints"

5. Dependency Management

# Find tokens that depend on CBIN-001
canary search "CBIN-001" | grep "DEPENDS_ON"

# Find what CBIN-005 blocks
canary list --json | jq '.[] | select(.Blocks | contains("CBIN-005"))'

Agent Integration

Workflow Before Storage

# Agent needs to scan manually
canary implement CBIN-001
# Shows locations but no priority info

Workflow With Storage

# Build index once
canary index

# Agent prioritizes work
canary list --status STUB --order-by "priority ASC" --limit 1
# Shows: CBIN-001 - JWTValidation (Priority: 1)

# Agent implements highest priority
canary implement CBIN-001 --feature JWTValidation

# Agent tracks progress
canary checkpoint "daily-checkpoint"

Benefits for Agents

1. Priority Awareness - Work on highest priority features first
2. Keyword Discovery - Find related features quickly
3. Phase Management - Understand project stages
4. Dependency Tracking - Know what blocks what
5. Progress Visibility - Checkpoints show completion over time

Performance
