docs: sharpen the attribution guarantee to a byte<->activation-key binding
Revised per PR #480 (#5607 owner clarification + #5608 codex resolution;
#5612 directs the update):

- The audit row no longer implies upstream observation or agent-only
  authorship. Reworded the guarantee: the row cryptographically binds
  commit bytes (control-plane-RECOMPUTED SHA) to access to the activation
  signing key, and binds that key to control-plane-owned activation
  metadata. An agent can sign arbitrary contents but cannot verify as a
  different activation or choose the recorded metadata.
- Control plane accepts gateway-delivered opaque bytes, independently
  recomputes the Git object ID, verifies the embedded signature against
  the activation key, and stamps its own metadata. Trusts no gateway
  SHA/key/verdict/metadata. No upstream fetch.
- Purged overclaims: removed "a compromised gateway cannot fabricate an
  audit binding" (the sidecar holds the signing capability, so it can —
  and that's acceptable under the intended guarantee), plus "accepted
  push" / "introduced upstream" framing.
- Resolved the control-plane-transport open question in-PRD (was left
  open; codex asked to resolve): transport is gateway bytes +
  recompute + verify; mirror-read is no stronger.

Issue: #423

Docs

How this project records what it builds and why — and a guide to picking the right document for what you're capturing.

When to write which document

Artifact For
Glossary (docs/glossary.md) Canonical term definitions — what words mean in this project.
PRD (docs/prds/) A feature: what to build, scope, success criteria.
Research note (docs/research/) A landscape/tradeoff investigation.
Decision record (docs/decisions/) A decision that isn't itself a feature — a policy, a convention, a "we will / won't do this," or a load-bearing choice made inside a larger PRD that deserves to be discoverable on its own.

A decision that's fully specified by a PRD doesn't need duplicating in a decision record. Write one when the decision would otherwise be buried in prose, lost in an issue thread, or have no in-repo home at all (small requests that don't merit a PRD; non-feature choices like merge strategy or a trust posture).
