What changed
context.request_retentionrequest-view capability so the current required persisted hook envelope and metadata-classified first/latest human messages survive compaction.The narrow tool-removal floor builds on public context work in 1f781cd; this PR does not import its broader assembly branch.
Why
Active reminder content and human request boundaries must remain available in compacted request views without changing message roles or the default behavior.
CI qualification and compatibility
The follow-up CI-only commit removes the development Git-main Core source mapping, locks development and CI to released
amplifier-core==1.6.1, and checks the requiredContextLengthErrorAPI before tests run. Runtime dependencies remain empty: Core is host-provided, and this module requires host Core>=1.6.1. No Core source or production implementation/test behavior changed.Verification
Limits
This is not a claim of a complete live-evaluation matrix, hard token ceiling, 1M-window behavior, or general-quality improvement. A live causal A/B remains unproven. Anthropic strict bare-JSON corroboration remains failing because otherwise-correct values were fenced.
Breaking changes
None. The capability is optional; existing request and canonical-history behavior remains unchanged. The supported host Core floor is
1.6.1.
