Actualize Knowledge Base

This command is a core part of maintaining a living assurance case. It keeps your FPF knowledge base (.fpf/) in sync with the evolving reality of your project's codebase.

The command performs a three-part audit against recent git changes to surface potential context drift, stale evidence, and outdated decisions. This aligns with the Observe phase of the FPF Canonical Evolution Loop (B.4) and helps manage Epistemic Debt (B.3.4).

Action (Run-Time)

Step 1: Check Git Changes

Run git commands to identify changes since last actualization:

# Get current commit hash
git rev-parse HEAD

# Check for changes since last known baseline
# (Read .fpf/.baseline file if it exists, otherwise use initial commit)
git diff --name-only <baseline_commit> HEAD

# List all changed files
git diff --stat <baseline_commit> HEAD

Step 2: Analyze Report for Context Drift

1. Review changed files for core project configuration:

   • package.json, go.mod, Cargo.toml, requirements.txt
   • Dockerfile, docker-compose.yml
   • .env.example, config files

2. If configuration files changed:

   • Re-read project structure (README, config files)
   • Compare detected context with .fpf/context.md
   • Present diff to user

3. Ask user if they want to update context.md

Step 3: Analyze Report for Evidence Staleness (Epistemic Debt)

1. Read all evidence files in .fpf/evidence/
2. Check carrier_ref field in each evidence file
3. Cross-reference with changed files from git diff
4. If a referenced file changed:
   • Flag the evidence as STALE
   • Note which hypothesis is affected

Step 4: Analyze Report for Decision Relevance

1. Read all DRR files in .fpf/decisions/
2. Trace back to source evidence and hypothesis files
3. If foundational files changed:
   • Flag the DRR as POTENTIALLY OUTDATED

Step 5: Update Baseline

Create/update .fpf/.baseline file:
