Summary

Raises the client-side availableActions limit in the startup request from 100 to 250, matching Odin, so an extractor with up to 100 actionable tasks (a start and a stop action each) plus custom actions can register.

Type of change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that changes existing behavior)
• Refactor (no functional change)
• Documentation update
• Chore / tooling / CI

What changed

• unstable/core/_dto.py: new MAX_AVAILABLE_ACTIONS = 250, used by AvailableActionList (was a hard-coded 100).
• tests/test_unstable/test_dto.py: available-actions max-length test uses the constant; the action-updates test stays at 100.
• tests/test_unstable/test_action_registration.py: 100 tasks (200+ actions) build a valid StartupRequest; MAX_AVAILABLE_ACTIONS tasks overflow and are rejected.
• CHANGELOG.md: Unreleased entry.

Why it changed

Each actionable task costs 2 actions, so the old cap of 100 allowed only 49 actionable tasks while Odin's task_limit is 100. A 50th task made the startup request invalid.

• Related issue: EDG-1049 (parent EDG-1031, bug bash Add None check function #2, DB-10 / KI-5)
• Related docs / discussion: failing loudly when a startup request is invalid is EDG-1032 (fix(odin): Make check-ins resilient to startup failures and transient network errors (EDG-1032) #588); Odin side: odin Remove newlines from log message #333

What to focus on during review

• The limit must stay in sync with Odin's MAX_AVAILABLE_ACTIONS; it is a duplicated constant, not shared.
• MAX_ACTION_UPDATES_PER_CHECKIN (100) is intentionally unchanged: excess updates carry over to the next check-in.

Test evidence

• uv run pytest tests/test_unstable/test_dto.py tests/test_unstable/test_action_registration.py -> 71 passed
• pre-commit run --all-files -> all hooks passed
• The wider tests/test_unstable suite has the same live-CDF failures/errors as clean master (no COGNITE_DEV_PROJECT locally); needs CI.

Risks and unknowns

• Must not be released before Odin Remove newlines from log message #333 is deployed: an older Odin rejects more than 100 actions with 422, which now fails the extractor at startup (EDG-1032).
• Larger startup payload, at most 250 actions; not load-tested.

Rollout and rollback

• Deploy Odin Remove newlines from log message #333 first, then release this.
• Revert restores the 100 limit; no config or migration.

Code Review

This pull request increases the maximum number of available actions sent at startup from 100 to 250 in the unstable package. This is achieved by introducing a new MAX_AVAILABLE_ACTIONS constant in _dto.py and updating the validation limits and test cases accordingly. I have no feedback to provide as the implementation is clean and well-tested.

Superseded by #596, which targets master directly (no dependency on the stacked PRs).
