den.ctx (Compatibility Shim)

Legacy API — Scheduled for Removal

den.ctx is a compatibility shim. It forwards entries to den.aspects and den.schema.<kind>.includes with deprecation warnings at evaluation time. It will be removed after the first stable release.

Migrate to:

• den.aspects for aspect definitions
• den.schema.<kind>.includes for entity inclusion
• den.policies for entity topology and routing

See Migrating from den.ctx for step-by-step instructions.

What it does

den.ctx was the original API for declaring aspects and binding them to entity resolution stages. It combined aspect definitions, cross-entity providers, and pipeline transitions in a single namespace.

The compatibility shim in modules/compat/ctx-shim.nix accepts den.ctx.* entries and forwards them:

den.ctx.<name> = { ... }
  ↓
den.schema.<name>.includes = [ <value with deprecation warning> ]

Each forwarded value emits a lib.warn at evaluation time telling you exactly what to change.

What replaced it

The den.ctx namespace was split into three independent concerns: den.aspects for aspect definitions, den.policies for entity topology, and den.schema.<kind>.includes for explicit activation.
