Why

Three older AgentSession files either rebuilt their own lower-level harness or used credential-gated provider calls that are skipped in required CI. The current deterministic suite harness already covers the broader retry, runtime, and compaction lifecycles.

What changes

• moves the exact transient-provider error classification table into the current retry integration suite
• adds one deterministic middle-conversation fork scenario covering selection metadata and retained history
• adds one deterministic normal-summarizer compaction scenario covering events, persisted metadata, rewritten context, and post-compaction usability
• removes the three older retry, branching, and compaction files

Coverage and cost

Unique assertions were moved before deletion; existing broader lifecycle tests remain unchanged.

Focused added coverage:

• six retry classification cases: 27 ms
• middle-prompt runtime fork: 290 ms
• normal-summarizer compaction lifecycle: 155 ms
• npm run check

The previous retry file took 38 ms for seven tests. The branching and compaction files were credential-gated and all eight tests were skipped in normal CI. Net reduction: 544 lines.

Note

Low Risk
Test-only refactor with no production code changes; minor risk that a dropped assertion (e.g. persistent content_filter retry cap) is no longer explicitly covered if not duplicated elsewhere.

Overview
Consolidates AgentSession integration coverage into the existing test/suite harness so CI no longer depends on API-key-gated real LLM runs or one-off runtime setup.

Deletes standalone agent-session-branching, agent-session-compaction, and agent-session-retry test files (~645 lines) and adds targeted cases to agent-session-retry-events, agent-session-compaction, and agent-session-runtime: a parameterized table of six transient provider error strings that should auto-retry; a full manual compaction path through the model summarizer (persisted compaction entry, compaction_start/compaction_end, post-compaction prompt); and fork scenarios for middle-of-thread history plus in-memory first-prompt forks with selectedText metadata.

Refactors runtime suite setup with an inMemory option on createRuntimeForTest, reusing it for the in-memory fork-at-position test instead of duplicating faux/runtime boilerplate.

Note

Consolidate AgentSession integration tests into suite directory

• Removes three standalone test files (agent-session-branching.test.ts, agent-session-compaction.test.ts, agent-session-retry.test.ts) and replaces them with consolidated coverage under test/suite/
• Adds compaction characterization tests verifying model-generated summaries, persistence, emitted events, and session reusability after compaction
• Adds parameterized retry tests covering network errors, content-filter, empty responses, and policy flags, asserting correct retry events and state
• Extends forking tests in agent-session-runtime.test.ts to cover forking before a middle prompt (with persistence) and before the first prompt in-memory, and refactors existing in-memory fork test to use the shared createRuntimeForTest helper
