Centralize workflow event semantics

[NathanColosimo]

Summary

• add targeted event type helpers and lifecycle classifiers in @workflow/world
• centralize eventData ref/payload field lookup for lazy-start and v4 split handling
• replace duplicated event/status groups across local, postgres, vercel, web-shared, web, and CLI

Tests

• ./node_modules/.bin/tsc -p packages/world/tsconfig.json
• ./node_modules/.bin/tsc -p packages/world-local/tsconfig.json --noEmit
• ./node_modules/.bin/tsc -p packages/world-postgres/tsconfig.json --noEmit

AI review: no blocking issues.

This pass only flags possible behavior changes introduced by the event-semantics centralization. None are clearly incorrect, but each is a semantic shift from the code it replaced and worth a maintainer's confirmation. See inline notes.

AI review: no blocking issues.

This pass only flags possible behavior changes introduced by the event-semantics centralization. None are clearly incorrect, but each is a semantic shift from the code it replaced and worth a maintainer's confirmation. See inline notes.

[NathanColosimo]

Summary

• add targeted event type helpers and lifecycle classifiers in @workflow/world
• centralize eventData ref/payload field lookup for lazy-start and v4 split handling
• replace duplicated event/status groups across local, postgres, vercel, web-shared, web, and CLI

AI review: no blocking issues.

This pass only flags possible behavior changes introduced by the event-semantics centralization. None are clearly incorrect, but each is a semantic shift from the code it replaced and worth a maintainer's confirmation. See inline notes.

Summary

• add targeted event type helpers and lifecycle classifiers in @workflow/world
• centralize eventData ref/payload field lookup for lazy-start and v4 split handling
• replace duplicated event/status groups across local, postgres, vercel, web-shared, web, and CLI

AI review: no blocking issues.

This pass only flags possible behavior changes introduced by the event-semantics centralization. None are clearly incorrect, but each is a semantic shift from the code it replaced and worth a maintainer's confirmation. See inline notes.

Summary

• add targeted event type helpers and lifecycle classifiers in @workflow/world
• centralize eventData ref/payload field lookup for lazy-start and v4 split handling
• replace duplicated event/status groups across local, postgres, vercel, web-shared, web, and CLI

Tests

• ./node_modules/.bin/tsc -p packages/world/tsconfig.json
• ./node_modules/.bin/tsc -p packages/world-local/tsconfig.json --noEmit
• ./node_modules/.bin/tsc -p packages/world-postgres/tsconfig.json --noEmit
• cd packages/world-vercel && ./node_modules/.bin/genversion --es6 src/version.ts && ../../node_modules/.bin/tsc --noEmit
• ./node_modules/.bin/tsc -p packages/web-shared/tsconfig.json --noEmit
• ./node_modules/.bin/tsc -p packages/cli/tsconfig.json --noEmit
• cd packages/world-vercel && ../../node_modules/.bin/vitest run src event
• cd packages/world-local && ../../node_modules/.bin/vitest run src
• cd packages/web-shared && ../../node_modules/.bin/vitest run

_{Avg deltas compare against the most recent benchmark run on main at the time of this run.}

_{Metrics — TTFS: time to first step body execution · STSO: step-to-step overhead (gap between consecutive step bodies) · WO: workflow overhead (time outside step bodies, client start → last step body exit) · SL: stream latency (first chunk write → visible to the reader)}

_{Scenarios — stream: one step that streams chunks back to the client; no hooks, so the run stays in turbo mode · hook + stream: registers a hook before the same streaming step, which exits turbo mode · 1020 steps: 1020 trivial sequential steps; STSO is measured between consecutive steps in the given step ranges}

_{🟢/🔴 mark percentiles within/above target. Targets (p75/p90/p99, ms) — TTFS 200/300/600 · SL 50/60/125 · STSO (1-20) 20/30/60 · STSO (101-120) 30/45/90 · STSO (1001-1020) 40/60/120}

_{TTFS/WO compare client vs deployment clocks and SL compares the step runner’s clock vs the client’s (NTP-synced in CI). WO ends at the last step body exit, the closest observable proxy for the final step-completion request.}
