Validation rules in integrity zome

[harlantwood]

Validations

• base of the TA link MUST be the (orig pubkey) of the DHT-level creator of the link
• link tag
  • MUST follow all of the rules of the data format: https://github.com/trustgraph/trustgraph-holochain#data-format
  • MUST have exactly 4 null bytes (no more or less)
• only agent who created a TA can delete it
• IMPL: anywhere we have existing validation code
  • move it to integrity zome
  • if appropriate, still call it from the coord zome

-CRUD operations can only be accessed by the acting agent
-max data size for entries and linktags
-check that TA exists
-registration to check that agent exists in DHT
-permissions for shareable TGs

Awesome thanks @dauphin3 -- incorporated some of these into description.

@harlantwood for the first box above in validations, would this only be true for forward TA's? Since the base of reverse could be AnyLinkableHash

The conceptual TA base is as you say. But the holochain link base is always the agent, regardless of direction.

correction: will need to handle forward & reverse

[dauphin3]

@harlantwood perhaps consider LinkType Directions, review found in #79

names are just simply Forward & Reverse... could be changed to TAForward, or TrustAtomForward, etc
