id(roc): finish the example migration: tic-tac-toe -> RocJson, roc-counter -> Screen, adopt RocText #565
Description
What and why
Two examples still use older patterns (hand-built JSON and a plain-text view), and RocText is imported by no example. Examples are what authors copy, and two of them still show the old hand-built JSON and plain-text patterns.
Source
- RPT §2 'Migration leftovers'
doc/2026-10-16T13-00-00Z_feature_world_apps_structured_migration/
RPT = doc/2026-10-18T18-40-00Z_report_platform_world_state/2026-10-18T18-40-00Z_report_platform_world_state.md, REF = doc/2026-10-18T00-00-00Z_reference_platform_state/2026-10-18T00-00-00Z_reference_platform_state.md. Both are uncommitted reports in the platform-world-apps-migration worktree.
Current status
Not started. grep -n 'RocJson\|Screen' pkgs/id/examples/tic-tac-toe/main.roc pkgs/id/examples/roc-counter/main.roc finds nothing; grep -l RocText pkgs/id/examples/*/main.roc finds nothing.
Acceptance criteria
- tic-tac-toe uses RocJson instead of hand-built JSON
- roc-counter renders through Screen
- At least one example imports RocText
- Modules are rebuilt with the pinned compiler and example tests pass

Prerequisites
- id(roc): F11.18 pin the Roc compiler for checked-in example modules and rebuild them in CI #541 — D1-018 F11.18 Pinned Roc compiler for checked-in example modules + CI rebuild job

Intake review
Fleet-monitor intake pass (2026-10-26). Body already carries a full
## Acceptance criteriasection, so this pass is label normalization plus a liveness check — no body edit.Verified live on main
e3467560(2026-10-26):grep -c 'RocJson\|Screen' pkgs/id/examples/tic-tac-toe/main.roc pkgs/id/examples/roc-counter/main.rocreturns 0 for both files, and no example'smain.rocimports RocText. The migration leftovers described in the issue are still exactly as filed.Related: prerequisite #541 (pinned Roc compiler + CI rebuild job) is itself still open and unenriched — the rebuild-with-pinned-compiler acceptance bullet cannot be verified until it lands. Sibling example-size work: #555.
Risks / notes: low risk; examples are the copy-source for authors, so the patterns matter more than the size suggests. The two source reports cited in the body live in an uncommitted worktree per the body's own note — the issue body is self-contained enough to work from without them.
Suggested approach: after #541 lands, migrate tic-tac-toe to RocJson and roc-counter to Screen in one PR, add RocText to the example where it fits most naturally, rebuild all examples with the pinned compiler, and run the example tests.

state: triaged (coverage pass)
Coverage pass 2026-11-03: reviewed in the fleet-wide per-issue pass (drift / overlap / already-handled / stale / blockers / ordering). Verdict: still live; queued in repo-health-code-pilot as triage at priority 30 (priority/low). If this is already handled at current main, the triage closes it with evidence; if it needs splitting, the triage files the split.
