| 2 | |
| 3 | **Issue:** #5 (Stdlib-Only Python Crawler) |
| 4 | **Period:** Phase 1 |
| 5 | **Timestamp:** 2026-05-18T10:26:47Z |
| 6 | |
| 7 | ## Objectives |
| 8 | - Implement stdlib-only Python crawler writing to `data/raw/YYYY-WNN.json` |
| 9 | - Support trending rank computation from prior snapshots |
| 10 | - Support pagination up to GitHub's 1,000-result limit |
| 11 | |
| 12 | ## Accomplishments |
| 13 | 1. **Crawler Implementation** |
| 14 | - Pure Python stdlib (`urllib`) with no external dependencies |
| 15 | - Default: top 250 search results per query |
| 16 | - Pagination support up to 1,000 results (GitHub's limit) |
| 17 | |
| 18 | 2. **Search Queries** |
| 19 | - Created: `created:>{date} stars:>50` |
| 20 | - Pushed: `pushed:>{date} stars:>50` |
| 21 | |
| 22 | 3. **Significance Filtering** |
| 23 | - Excludes forks |
| 24 | - Excludes repos without descriptions |
| 25 | - Excludes repos without READMEs |
| 26 | - Excludes obvious tutorial/homework/template repos |
| 27 | - Handles SAML-blocked README endpoints gracefully (skip vs fail) |
| 28 | |
| 29 | 4. **Data Output** |
| 30 | - Writes `data/raw/YYYY-WNN.json` for weekly snapshots |
| 31 | - Computes trending rank from latest prior snapshot when available |
| 32 | |
| 33 | ## Benefits |
| 34 | - Minimal CI setup (no external dependencies) |
| 35 | - Deterministic crawls (repeatable results) |
| 36 | - Cheap execution (suitable for local and Actions runs) |
| 37 | - Path to deeper crawls without breaking data contract |
| 38 | |
| 39 | ## Status |
| 40 | ✅ COMPLETE (Issue #5 closed, implementation in PR #25-#26) |
