CORE CONCEPTS / 04

No destination needs the whole story.

Bounded semantic compartments for multi-model and multi-tool workflows.
SHARD groups protected paragraphs by bounded purpose so separate destinations can receive only the context relevant to their subtask. It reduces concentration of context; it does not create anonymity or guarantee unlinkability.
CURRENT ALPHA

Deterministic compartment preview

  1. 01

    PROTECT

    Run the same detection, minimization, policy, and transformation layers used by a normal protect request.

  2. 02

    GROUP

    Classify paragraphs into bounded purpose categories with deterministic rules.

  3. 03

    CAP

    Return between two and eight shards, constrained by max_shards.

  4. 04

    ROUTE

    Give each destination only its required protected_text. Provider fan-out is application work in the current alpha.

  5. 05

    SYNTHESIZE

    Combine protected outputs locally or in another deliberately scoped stage.

API SHAPE

Create bounded shards

CURLbash
curl http://127.0.0.1:8787/v1/shard \
  -H "Authorization: Bearer $SHREDDAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "authorized multi-section source",
    "task": "separate commercial, security, and legal review",
    "policy_id": "strict-v1",
    "privacy_mode": "strict",
    "max_shards": 4
  }'
THREAT BOUNDARY

What sharding does not solve

  • A provider may infer relationships from a small distinctive fact set.
  • Colluding destinations can recombine separate shards.
  • Repeated requests can create longitudinal linkability.
  • A bad task definition can place too much context into every compartment.
  • Sharding does not protect data once an authorized destination receives it.
