Problem

experimentActions still lives under frontend/src/scenes/experiments. It belongs in the experiments product folder.

Changes

Mechanical move of experimentActions to products/experiments/frontend. All importers now use the products/ path. No behavior change.

How did you test this code?

pnpm --filter=@posthog/frontend typescript:check

Manually refactored: no

Skills used:

• /stacking-prs (local)
• /writing-ui-components (local)
• /writing-pull-requests (local)

Relevant decisions:

• Each file moves in its own stacked PR, so review stays small and mechanical.
• Components go to products/experiments/frontend/components; helper modules go to the frontend root. No ../ imports.

✅ Eager graph — within budget

How much code each root ships on the eager path — downloaded and parsed before the surface is interactive. Measured from the esbuild output chunks (post-tree-shake, static imports only); lazy import() / React.lazy chunks are not counted.

✅ Toolbar bundle — eager 2.26 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

Metric	Size	Δ vs base	Budget
Eager (shipped) entry + static imports	2.26 MiB · 18 files	no change	████░░░░░░ 39.5% of 5.72 MiB
