# PDS File Reorganization Implementation Plan
2
+
3
+
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
4
+
5
+
**Goal:** Reorganize pds.js into logical domain sections with box-style headers for improved readability.
6
+
7
+
**Architecture:** Reorder existing code into 12 logical domains without changing functionality. Add Unicode box-style section headers. Group related utilities that are currently scattered.
8
+
9
+
**Tech Stack:** JavaScript, JSDoc
10
+
11
+
---
12
+
13
+
## Box Header Format
14
+
15
+
All section headers use this format (80 chars wide):
16
+
```javascript
17
+
// ╔══════════════════════════════════════════════════════════════════════════════╗
18
+
// ║ SECTION NAME ║
19
+
// ║ Brief description of what this section contains ║
20
+
// ╚══════════════════════════════════════════════════════════════════════════════╝
21
+
```
22
+
23
+
---
24
+
25
+
### Task 1: Types & Constants Section
26
+
27
+
**Files:**
28
+
- Modify: `src/pds.js` (lines 17-84, plus scattered constants)
29
+
30
+
**Step 1: Create the new section header and gather all types/constants**
31
+
32
+
Move these items to the top (after the file header comment):
33
+
- `CBOR_FALSE`, `CBOR_TRUE`, `CBOR_NULL`, `CBOR_TAG_CID` (from lines 19-24)
34
+
- `CODEC_DAG_CBOR`, `CODEC_RAW` (from lines 480-481)
35
+
- `TID_CHARS`, `clockId`, `lastTimestamp` (from lines 563-566)
36
+
- `P256_N`, `P256_N_DIV_2` (from lines 638-641)
37
+
- All typedefs: `Env`, `BlockRow`, `RecordRow`, `CommitRow`, `SeqEventRow`, `BlobRow`, `JwtPayload`
38
+
39
+
Add header:
40
+
```javascript
41
+
// ╔══════════════════════════════════════════════════════════════════════════════╗
42
+
// ║ TYPES & CONSTANTS ║
43
+
// ║ Environment bindings, SQL row types, protocol constants ║
44
+
// ╚══════════════════════════════════════════════════════════════════════════════╝
45
+
```
46
+
47
+
**Step 2: Run typecheck to verify no breakage**
48
