- Inject progressive per-checkpoint hints into all 40 checkpoint pairs
  (80 EN/ZH lesson files); DA lessons gain full frontmatter so they
  enter the content manifest like the other courses.
- paths/foundation/path.json declares the first-agent branch group so
  the site can treat Claude Code / Codex modules as alternatives.
- Record real-agent solvability runs (Devin, SWE-2 Max) in all 8 course
  REVIEW.md files — challenge-mode runs with observed deviations noted;
  starters restored and --expect-failure re-verified.
- Regenerate content-manifest.json; update repo-plan status lines.
- Verified: verify_courses (8/8), verify_examples (5/5), manifest,
  catalog export, and readme rendering checks all green.

# Conflicts:
#	docs/repo-plan-0.0.4.md

Licensing and entry points:
- CONTRIBUTING permissions now match the dual MIT/CC-BY LICENSE
- README_cn hero rewritten for the challenge-platform narrative (TASK.md
  contracts, verify.py claim codes, paths badge routes)
- llms.txt: fix four template paths, add the three DA courses, refresh
  tagline and Radar description

Indexes and governance docs:
- README/CONTRIBUTING/AGENTS: complete the CI check list
  (verify_courses, verify_paths, --target both), add courses/, paths/,
  radar.json to the structure diagram, dependency-aware course contract
- CHANGELOG: record post-0.1.0 0.0.4 phase A under [Unreleased]
- CONSUMING: document radar.json as the third pinned export
- repo-plan-0.0.4: mark FP-334 done (v0.1.0)

Courses and examples:
- mcp-server-in-python: fix stale examples/mcp-server verify path in
  TASK pair; expect-failure now requires all named failures; REVIEW
  wording matches the actual scenario layout
- da-report: remove the unused pandas gate (verify.py, requirements,
  COURSE pair) — the course is stdlib-only
- agent-rules L01 pair: add the missing verifier command
- product-slug: fix punctuation-before-collapse ordering so removed
  punctuation cannot create duplicate separators; regression test added
- async-fetcher: solution uses asyncio.TaskGroup; TASK pair states the
  total-attempts retry semantics
- structured-pipeline: solution actually iterates in batch_size batches
- pydantic-validation: honest stdlib-by-design note (EN+ZH) and accurate
  verify message
- align DA badge ids to the course- prefix convention

Bilingual parity and paths:
- templates: add CODE_REVIEW/IMPLEMENTATION_PLAN CN pairs and link them
  from both indexes; fix EVAL_RECORD/AGENT_RULES CN drift
- guides: fix async-patterns_cn example, modern-typing_cn dropped
  clause, migrate guide EN em-dash sentence
- playbooks: CN footers deep-link the same resources anchors as EN
- paths: add README pair, resolve undefined C1-C4 labels to course
  slugs, link the index from the main READMEs

Hygiene:
- drop committed course .venv/__pycache__ artifacts, ignore
  .pytest_cache, exempt starter scaffolding imports from ruff F401

Validation: pytest 136 passed; ruff clean; catalog/radar/README/manifest
checks current; 5 examples, 8 courses, 2 paths verified.

- Rename hands-on-with-openai-codex-cli → hands-on-with-openai-codex and
  rewrite all content for the Codex desktop app (threads, approvals,
  AGENTS.md, diff review); course_id course-codex-cli and salt preserved.
- Add four new report-tool core courses authored from official docs:
  hands-on-with-cursor, hands-on-with-deepseek-harness,
  hands-on-with-kimi-code, hands-on-with-zcode. Each ships EN+ZH
  COURSE/lessons, honest REVIEW.md (docs-authored, live run-through
  pending), and a verify.py with its own course_id + salt.
- Enforce shared-core byte equality via core-group marker checked by
  tools/verify_courses.py.
- Foundation path: first-agent branch now offers all six tools; m0
  orientation and route-challenge rewritten accordingly (any two tools).
- tools/claim_receipt.py + verify.py receipt support and
  build_solution_hashes.py → course-solutions.json (claim receipts A-side).

…urse lesson 1 rework

FP-820: python verify.py (no args) is the learner's command on all 12
free courses, 3 pro courses, and the data-analysis capstone - suite
status, per-checkpoint claim codes, English-first output, non-zero exit
while gated checkpoints are open. Published progress --json and
--receipt-out formats unchanged; the four explicit usages stay for
maintainers.

FP-821: verify_courses.py copies each course plus tools/claim_receipt.py
into an isolated tree and enforces the default command + receipts there.

FP-822: six agent-tool courses' lesson 1 (EN+ZH) rewritten to the fixed
order tool -> FlyPython Skill (network on) -> agent fetches the course
files; download wording removed from COURSE.md and lessons; solution no
longer the completion standard.

FP-823: prose checkpoints in three 0.0.3 courses became question lists
for the human-in-the-loop gate.

FP-824: README/README_cn start section leads with the Skill entry
sentence and the six tool courses.

…0.1.0)

First draft from the parallel planning session: permanently-free community
courses, review states, and open questions. Referenced by the website's
0.0.9 plan revision 4.

- paths/foundation: m0 orientation is now an optional extra-credit module
  (never first step, never badge-required); verify_paths understands
  "optional" and badge math excludes it. Route-challenge copy: the module
  pages live on flypython.com now, repo keeps the canonical markdown.
- six tool-course L01s (en+zh): step 2 pre-installs the Skill as optional
  (the entry sentence reads it from the URL); starter failure count
  corrected to "five classes + two end-to-end consequences = seven named
  failures".
- READMEs: new positioning line, same change both languages.

make check green (12 courses, 2 paths).

FP-1012: docs/repo-plan-0.1.0.md -> docs/repo-plan-0.1.x.md (community
courses are a post-launch 0.1.x track, not the launch version); CHANGELOG
gains the 0.0.9 and 0.1.0 sections recording FP-983/FP-984 and the rename.

FP-1012: pyproject 0.1.1 (the v0.1.0 tag stays immutable on e420fca);
CONTRIBUTING gains the release/tag rules — tags immutable, independent
repo/website versions linked by CHANGELOG + Release mapping, website
consumes only a pinned full SHA. CHANGELOG records the v0.1.0-website /
v0.1.1-repo compatibility.
