Function validate_namespace

pub fn validate_namespace(ns: &str) -> Result<()>
Expand description

Validate a namespace (flat or hierarchical, Task 1.4).

Flat namespaces ("global", "ai-memory") remain fully valid — hierarchy is opt-in. Hierarchical paths use / as the segment delimiter:

alphaone/engineering/platform

Rules:

  • Not empty, no leading/trailing whitespace
  • Length ≤ [MAX_NAMESPACE_LEN] (512 chars)
  • Depth (segment count) ≤ MAX_NAMESPACE_DEPTH (8)
  • Backslashes, null bytes, control chars, and spaces are forbidden
  • Leading and trailing / are forbidden (normalize input via normalize_namespace before validating)
  • Empty segments (consecutive //) are forbidden
  • Each segment is non-empty; no further character restriction beyond the whole-string checks above (preserving historical flexibility for existing flat namespaces like ai-memory-mcp-dev)
