Ticket-linked hotfixes
Ship a workaround under incident pressure. Tie it to the tracking issue. When the issue closes, CI marks the shim ready and Pro opens a removal PR.
Use cases
Built for the code you meant to delete
Real patterns teams annotate with Expiry — not generic "tech debt" hand-waving.
Dependency migration shims
Keep a compatibility layer until React 19, Node 22, or your internal SDK crosses the version line. Expiry reads the lockfile — no spreadsheet maintenance.
Feature-flag experiments
Code behind NEW_CHECKOUT should vanish when the flag goes to 100%. Annotate the branch; delete when LaunchDarkly (or your env) says enabled.
Environment sunsets
Legacy auth paths, dual-write tables, and config switches tied to a deprecated environment. Gone when the env var disappears from production.
Compliance & audits
SARIF export and health scores show auditors exactly which temporary code exists and when it becomes deletable.
Data & ML pipelines
Backfill scripts and one-off transforms marked until the warehouse migration completes.
When a condition is met
Free tier marks annotations ready, fails CI if overdue, and posts a PR comment. Pro opens a draft removal PR for your team to review and merge.
