[web-shared][cli][ci] Add serializable reviver compatibility check

[karthikscale3]

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

• Vercel: failure

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

❌ Some benchmark jobs failed:

• Postgres: success
• Vercel: failure

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

❌ Some benchmark jobs failed:

• Local: success
• Postgres: success
• Vercel: failure

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

❌ Some benchmark jobs failed:

• Local: success
• Postgres: success
• Vercel: failure

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

• Postgres: success
• Vercel: failure

Check the workflow run for details.

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."

Summary

• add a dedicated CI job that builds the CLI and web-shared reviver packages, then runs a serializable reviver compatibility test
• add a web-shared test that discovers every SerializableSpecial key from core and verifies web-shared and CLI can hydrate each one
• cover RuntimeDecryptionError in web-shared and add missing CLI error reviver keys for HookConflictError and RuntimeDecryptionError

Why

The trace-viewer failure happened because a serializable type could be emitted by core without a matching browser-side reviver. This check makes that mismatch fail in CI for both web-shared and CLI.

Validation

• pnpm turbo run build --filter='@workflow/cli' --filter='@workflow/web-shared'
• pnpm vitest run packages/web-shared/test/serializable-revivers.test.ts
• pnpm --filter @workflow/web-shared test
• pnpm --filter @workflow/web-shared typecheck
• pnpm --filter @workflow/cli typecheck
• git diff --check --cached

[github-actions]

Backport to stable failed — the cherry-pick had conflicts that could not be resolved automatically (backport job run).

To resolve manually, push a backport branch and open a PR against stable (the workflow never pushes directly to stable). Note: this repository requires verified signatures on every branch, so your local commits must be signed (git config commit.gpgsign true with a configured GPG/SSH signing key, or git cherry-pick -S).

git fetch origin stable
git checkout -b backport/pr-2250-to-stable origin/stable
git cherry-pick -S 5bf2c167a56298a2480e451c9fba72282f93496a # -S signs the commit# Fix conflicts, then:
git add -A
git cherry-pick --continue
git push -u origin backport/pr-2250-to-stable
gh pr create --base stable --head backport/pr-2250-to-stable \
--title "Backport #2250: <original PR title>" \
--body "Manual backport of #2250 (cherry-pick 5bf2c167a562) to \`stable\`."
