Step 1: Collect (Phase 1)

Module: junior.collect.local -> junior.collect.core.collect.collect_base()

Runbook: git diff -> parse changed files -> commit messages -> extra context.

Input

Parameter	Value
project_dir (env CI_PROJECT_DIR)	.
target_branch	main
base_sha	(none)
collector	local

Output: CollectedContext

{

  "mr_iid": 0,
  "mr_title": "",
  "mr_description": "",
  "source_branch": "",
  "target_branch": "main",
  "labels": [],
  "commit_messages": [
    "feat: add authentication and database layer\nImplement user authentication with token-based sessions\nand SQLite database for user management.",
    "feat: add API endpoints and integrate auth with greetings\nAdd REST-like handlers for login, registration, search,\nadmin actions, and webhook processing.\nUpdate hello.py to support authenticated greetings."
  ],
  "full_diff": "<11,801 chars — full unified diff of 4 files>",
  "changed_files": [

Key Metrics

Metric	Value
Diff size	11,801 chars
Changed files	4
Commits parsed	2
Extra context	none

Notes

• Local collector skips MR metadata (title, description, labels) since there’s no API
• source_branch is empty because local collector doesn’t query git for current branch name
• Each ChangedFile contains both the unified diff and full file content
