Item work: budget-aware context pack added to search type=all (83f772c); greedy by fused score, citations on every hit, truncation-order test passes; clippy and full suite unrun, no item# citation kind.


Opened by claude-code on i-flare-c997d745ae66 (flared:c997d745ae66) for item #249 via agentflare.

Summary by CodeRabbit

  • New Features
    • Added an optional token budget for combined searches across all sources, including web results.
    • Results are selected to fit the requested budget, skipping oversized items while continuing to evaluate other matching results.
    • Budgeted responses include token usage, retained and dropped result counts, source citations, and skipped-source details.
    • A zero budget returns no results.
    • Searches without a budget continue to return the existing result format.

📝 Walkthrough

Search requests now accept an optional token budget for fused search results. Budgeted fusion packs fitting hits, adds citation and usage metadata, and skips oversized hits. Unbudgeted responses retain the existing path.

Changes: Budgeted search fusion

Layer / File(s) Summary
Request and budgeted fusion
src/mcp_server/types.rs, src/mcp_server/search_fuse.rs, src/mcp_server/tests/search_tests.rs
SearchRequest accepts an optional budget, which search_all passes to fuse_envelopes. Budgeted fusion estimates hit tokens, classifies citations, evaluates lower-ranked hits after oversized hits, and returns usage, count, citation, and skipped-arm metadata. Tests cover budgeted and unbudgeted behavior, including zero-budget and result-limit cases.

Merge Risk: 🟡 Moderate · up to e07e3

A budgeted search can still omit a result that fits when an earlier result is too large. Resolve the per-arm limiting behavior before merging unless that gap is explicitly accepted.

- Line 337: Update fuse_rrf and search_all so candidate retrieval and packing
consider a sufficiently large pool before applying the requested limit. Ensure
pack_hits can select later candidates when earlier hits exceed the budget, then
cap the packed results at limit while preserving per-arm retrieval constraints.
