Query Knowledge

Search the FPF knowledge base and display hypothesis details with assurance information.

Action (Run-Time)

• Search .fpf/knowledge/ and .fpf/decisions/ by user query.

• For each found hypothesis, display:

• Basic info: title, layer (L0/L1/L2), kind, scope

• If layer >= L1: read audit section for R_eff

• If has dependencies: show dependency graph

• Evidence summary if exists

• Present results in table format.

Search Methods

By Keyword

Search file contents for matching text:

/fpf:query caching

-> Finds all hypotheses with "caching" in title or content

By Specific ID

Look up a specific hypothesis:

/fpf:query redis-caching

-> Shows full details for redis-caching

-> Displays dependency tree

-> Shows R_eff breakdown

By Layer

Filter by knowledge layer:

/fpf:query L2

-> Lists all L2 hypotheses with R_eff scores

By Decision

Search decision records:

/fpf:query DRR

-> Lists all Design Rationale Records

-> Shows what each DRR selected/rejected

R_eff Display

For L1+ hypotheses, read the audit section and display:

**R_eff Breakdown**:

- Self Score: 1.00

- Weakest Link: ev-research-redis (0.90)

- Dependency Penalty: none

- **Final R_eff**: 0.85

Dependency Tree Display

If hypothesis has depends_on, show the tree:

[api-gateway R:0.80]

  └──(CL:3)── [auth-module R:0.85]

  └──(CL:2)── [rate-limiter R:0.90]

Legend:

• R:X.XX = R_eff score

• CL:N = Congruence Level (1-3)
