refactor: remove semanticCompact #3550
Description
Problem
semanticCompact is an off-by-default attention experiment with its own policy, controller state, validation, telemetry, and Agent Loop integration.
historyCompact now covers manual, pre-turn, mid-turn, and overflow compaction. Discussion #3541 confirmed that we have no current use case or controlled evaluation showing that the separate semanticCompact path improves task outcomes enough to justify another mechanism.
Desired outcome
- Remove the
semanticCompactproduction path, configuration, protocol fields, state, telemetry, tests, and documentation. - Keep
historyCompactas the only Runtime context-compaction mechanism. - Do not retain dormant flags or a compatibility path.
- Preserve the canonical RuntimeEvent ledger so the experiment can be reconsidered later if evidence emerges.
Implementation will be included in #3545 so the repository moves directly to the single-path final state.
Drafted with Codex. I reviewed the repository context and own the proposal.

I’ll take this and fold the removal into #3545 so we land the single-path architecture without an intermediate state. I’ll remove
semanticCompactend to end rather than leave dormant configuration or compatibility code.fix: unify context compaction
