- Remove duplicate #66884 alexlomt entry from top Unreleased > Fixes;
the canonical entry already lives under 2026.4.24 (Unreleased) per
Mason Huang's earlier 'move #66884 entry to 2026.4.24' commit.
- Reflow the wrapped 3-line Tool Access bullet (#71405) onto a single
line so it matches every other bullet in the section.
Three external-contributor commits from the last day landed without
CHANGELOG entries:
- Alex Fries (#68286, @ajfonthemove): hybrid memory search component
scores. Added under Unreleased > Changes (feat).
- Charles Dusek (#51267, @cgdusek): malformed tool-result text-block
guard. Added under Unreleased > Fixes.
- Jerome Benoit (#59935, @jerome-benoit): Nix Home Manager daemon PATH
support. Added under Unreleased > Fixes.
Also drop a duplicate raw-subject changelog line for #66884 that
restated alexlomt's already-formatted entry one line above.
Expose raw `vectorScore` and `textScore` alongside the combined hybrid memory search `score`.
- Preserve vector/text component scores from `mergeHybridResults` output.
- Add optional component-score fields to both memory host SDK type surfaces.
- Extend hybrid merge tests for vector-only, text-only, and overlapping result cases.
- Document that component scores remain raw retrieval diagnostics while temporal decay/MMR only adjust or reorder the combined ranking `score`.
Closes#68166.
Maintainer verification:
- `pnpm test extensions/memory-core/src/memory/hybrid.test.ts`
- `pnpm check:changed`
- Fresh GitHub checks passed.

Harden context pruning and tool-result character estimation against malformed `{ type: "text" }` blocks created by void/undefined tool handler results.
- Require text blocks to carry a string before using `.length` in the tool-result estimator.
- Guard context-pruning text/image loops against malformed and null content entries.
- Serialize malformed non-string text blocks for pruning size accounting so they cannot bypass trimming as zero-sized.
- Add regression coverage for malformed text blocks, null entries, and non-string text payloads.
Closes#34979.
Maintainer verification:
- `pnpm test src/agents/pi-embedded-runner/tool-result-char-estimator.test.ts src/agents/pi-hooks/context-pruning/pruner.test.ts`
- `pnpm check:changed`
- GitHub checks passed, including the OpenAI / Opus 4.6 parity gate.
Based on prior work by #39331 and #34980.
