Compose decisions and conditional generation with generic typed flows - #116
Conversation
📝 WalkthroughWalkthroughThe change adds a bounded typed-flow runtime with decision, data, and JSON-generation nodes. Selective compaction now prepares and executes a typed flow. The endpoint, examples, documentation, and tests cover routing, limits, fallbacks, tracing, and protected content. ChangesTyped flow runtime

Preserve policy-admission errors.
When fragment execution reaches a leg, this catch treats policy-admission errors like provider failures and returns retained content. The existing /v1/compact path maps the same errors to HTTP 400. An invalid summary_policy can occur after decision calls complete, so a decision leg can incur cost before the request returns a successful no-op.
Re-raise only policy-admission exceptions from compact_fragments. Catch them around the fragment call in shim.py and translate them with _invalid_policy_response. Continue retaining original fragments for provider failures, timeouts, and invalid model output. Add endpoint tests for invalid policies on both legs.

Apply the configured request deadline to selective compaction.
The selective-compaction flow uses a fixed 40-second flow deadline. This direct call does not apply request_deadline_ms, so a shorter configured deadline can be exceeded. The active provider call is cancelled only when the flow deadline expires.

Sigma flows can now classify typed data, select records and generate only when needed. Add native
decisionnodes and deterministicdataoperations (project,select,overlay,union) to the shared flow runtime, with JSON generation, empty-input skipping, explicit input fallback, node timeouts and a shared 40-second typed-flow budget. Callers use the existing chat endpoint withflow_irandflow_input.Conversation compaction is a JSON preset over that runtime.
/v1/compactprepares bounded message units and static questions, executes the same admitted flow, then renders the result in message order. The adapter performs no inference. The separate compaction inference scheduler is removed. An independent ticket-triage example and engine-backed tests exercise classification → selection → conditional generation → overlay without any agent or compaction code.System/developer messages, pinned user input and complete recent units remain protected. Oversized evidence and failed/invalid/truncated summaries retain original units; excerpt-only decisions cannot authorize archive. The 10% target measures UTF-8 bytes and is best-effort. Clients retain original transcripts. Each node carries routing/accounting metadata; unknown attempted-call cost makes the total unknown, including when a fallback preserves input. Deterministic and skipped nodes cost zero. Existing unextended flow encoding and legacy
/v1/compactbehavior are preserved.Core dependency genlayerlabs/unhardcoded-engine#33 is merged. The core submodule is pinned to its main commit
e3c5f53849d108192d0c32e4365d685916d2008fin router commitd9b7147; its tree is identical to the previously tested branch commit. This PR is the next merge. SubZeroClaw genlayerlabs/subzeroclaw#30 keeps the same compaction API. No deployment or paid inference is performed as part of this refactor.Validation: full CI passed on
2bfd747(run): 1,033 Python tests passed (2 existing skips), 724 core assertions passed, and router/AntSeed image build and boot checks passed. The submodule-only updated9b7147triggers a fresh CI run. Focused local checks: 80 tests plus the documented ticket-preset integration test. The BDD admission scenario resolves all steps in dry-run; no live BDD or model performance claims.A broad macOS run against PostgreSQL tunneled to Marte was interrupted at 109 passes and two concurrency/timing failures (one-second connection lease and subsecond overlap assertions); those tests pass in the full CI run with its local PostgreSQL service. No full local-suite success is claimed.
