Workshop simulation repairs: browser path, model-access gate, active learning

[Copilot]

Three targeted fixes from the 2026-07-21 workshop simulation report (26.8% overall success rate, 20.7% dropout at 02-setup, copilot-access-missing as top step-7 failure, active_learning score of 1.7 in step 5).

Add zero-install browser/CCA path (02-setup)

• New workshop/02c-setup-browser.md (<!-- page-journey: ui -->) — creates the practice repo on github.com, no terminal or Codespace needed
• 01-prerequisites.md: replaces buried [!TIP] with an explicit three-option comparison table and adds <!-- journey: ui,copilot --> routing to 02c
• 06-install-gh-aw.md: adds <!-- journey: ui,copilot --> bypass that skips CLI install and routes directly to step 7

Strengthen model-access pre-flight gate (07d-confirm-model-access)

"Verify model access with a test prompt" moved from the end of the page to the beginning, before billing configuration. Learners who lack Copilot access now fail fast instead of completing the billing steps first. The [!IMPORTANT] callout now links to the Copilot troubleshooting side quest.

Raise active_learning in step 5 (05-agentic-workflows-intro)

Added a "Try it: write a one-sentence task brief" exercise with a worked example and three checklist items — the first hands-on activity on an otherwise read-heavy page. active_learning score: 1.7 → 2.6 (activity density 0.53 → 0.79).

workshop/07d-confirm-model-access.md:29

Rule violated: Alert callouts — no alarmist language

Offending text:
> Do not continue if you received an error instead of a response. Fix the access issue now — model-access errors will cause Step 8 to fail and are much harder to diagnose mid-run.

Suggested fix: Per the guidelines, callout body text must never use dramatic or alarmist language — keep the tone calm and matter-of-fact even at the [!IMPORTANT] level. Rewrite, for example:
> If you received an error instead of a re…

workshop/01-prerequisites.md:3

Rule violated: Dispatcher page annotation — <!-- learning:false --> misuse

Offending text:

<!-- learning:false -->

Suggested fix: The guidelines state that <!-- learning:false --> should only be applied to pure routing/navigation pages containing no hands-on activities, no checkpoints, and no substantive technical instruction. This page includes a 'Verify AI engine access' section that directs learners to check github.com/settings/copilot — that is a hands-on verific…

workshop/02c-setup-browser.md:9

Rule violated: Header style — non-descriptive heading

Offending text:

## Steps

Suggested fix: The guidelines require descriptive headings that tell learners what they are about to do. Replace ## Steps with something specific like ## Create your practice repository — this lets a learner scanning the page immediately understand the scope of the section.
