Context and memory architecture

Lab: build a scoped memory store

exerciseSelf-paced

Assignment

Create two users, three temporary facts, two explicit preferences, and one later correction. Use synthetic values only.

Build sequence

  1. Define working and persistent record schemas with provenance and expiry.
  2. Implement scope-filtered lookup, correction, and deletion.
  3. Summarize a conversation containing a qualified statement and inspect whether uncertainty survives.
  4. Test context reconstruction after a user switch.

Acceptance checks

  • No user can retrieve another user’s records.
  • Expired and deleted facts are absent from future context.
  • The summary retains material uncertainty and links to its source.

Evidence to keep

Submit the working artifact or decision document described above, the inputs used, and the observed results for every acceptance check. Include one failed attempt and the change you made after investigating it. Label fixture-based outcomes separately from live-system measurements. These artifacts become part of your final portfolio review.
