Vijay Janapa Reddi	7fdb49ee5c	feat(labs): gold-standard polish — stakeholders, hover templates, test fixes ... - Add 16 stakeholder messages to Vol2 labs 10, 11, 12, 15 (4 per lab) - Add 32 Plotly hover templates across 6 labs with units and precision - Fix Lab 00 DecisionLog dataflow bug (missing from cell return + signature) - Fix test_widget slider regex to handle Python underscore literals (100_000) - Fix test_widget slider count test: check total controls, not just sliders - Fix test_engine to skip gracefully when marimo is not installed - Standardize 4 chart heights from 420-450px to 380px Tests: 1,326 passed, 28 skipped, 0 failed (full suite)	2026-04-02 07:14:13 -04:00
Vijay Janapa Reddi	171e9a6de0	fix(labs): fix style.py f-string escaping, lab_16 cell dataflow, and clean up test suite ... - style.py: escape CSS @keyframes braces for Python f-string (was breaking all 33 labs) - lab_16: rename _axes/_target_met/_effective_gain to remove underscore prefix so Marimo dataflow wires them between TABS and LEDGER_HUD cells - components.py: add FailureBanner component for OOM/failure state visuals - test_engine.py: remove test_app_defines_core_variables (always skipped, Marimo cells don't export to module namespace) - CI workflow: remove 4 redundant bash validation steps (pytest covers them)	2026-03-22 08:43:24 -04:00
Vijay Janapa Reddi	3a555deabd	feat(labs): rebuild all 32 labs with chapter-grounded parts, ed-tech review fixes, and test infrastructure ... Complete lab curriculum rebuild: - 16 Vol1 + 16 Vol2 labs (33,368 lines across 32 files) - Each lab has 4-5 pedagogically grounded parts + synthesis - Parts proposed by agents reading actual chapter QMD files - Ed-tech review identified and fixed: redundancies, time overruns, mlsysim gaps - V2-03 + V2-06 merged into "Communication at Scale" - 17 old/superseded files deleted (pre-merger, pre-renumber) Structural fixes applied: - V1-01 Part C replaced (Silent Decay -> Triad Across Targets) - V1-03 grounded in mlsysim (Engine.solve for OOM, Engine.sweep for configs) - V1-09 Part C replaced (Curriculum Learning -> Preprocessing Tax) - V1-13 Part E dropped (redundant with Lab 10) - V1-15 Part C dropped (TCO not fairness-specific), refocused - V2-12 model extraction dropped, restructured around privacy cost - V2-16 capstone cut to 4 parts, Design Ledger fallbacks added - All 15-min parts trimmed to 12 min Test infrastructure added: - labs/tests/ with 3-level pytest suite (static, engine, widget) - CI workflow updated with pytest stages - pytest added to labs/requirements.txt	2026-03-15 16:26:50 -04:00
