Memory Architecture: Org Memory Discovery Replaces Personal/Team Sync

What

The old personal and team memory sync backend — which replicated .md/.txt files against /api/claude_code/memory and /api/claude_code/team_memory — has been replaced by a new org memory system. Shared memory stores are now discovered automatically from the server; there is no more per-repo sync loop in the client.

Details
  • Claude Code calls a new /v1/code/local/memory/mounts endpoint to discover which org memory stores are available for the current account.
  • Discovered stores are cached locally in org-memory-discovery.json (under the cache directory) and refreshed once per hour.
  • Credential provisioning uses a new /v1/code/local/memory/credential endpoint, with a configurable token lifetime.
  • The feature is controlled by the tengu_haze_glass feature flag (off by default during rollout) and can be disabled with CLAUDE_CODE_DISABLE_ORG_MEMORY=1.
  • Directory listing now uses a streaming NDJSON protocol (exportMetadata) when the backend supports it, falling back to paged listing on older backends. The stream path can be disabled with CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST=1 or the tengu_memory_stream_list flag.
  • Mount directories that already contain unmanaged content before the store is mounted are suppressed with a warning rather than overwriting user files: "mount dir exists without a .memory-sync manifest and is not empty — suppressing sync".
  • The environment variable CLAUDE_CODE_DISABLE_ORG_MEMORY is new. CLAUDE_MEMORY_STORES still overrides store configuration.
  • ANTHROPIC_BEDROCK_MANTLE_API_KEY (an old Bedrock-specific key type) has been removed.

Read from
Feature flag
tengu_haze_glass Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.210: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

tengu_memory_stream_list Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

What has happened since
Flag reading moved The flag server now returns off for tengu_haze_glass, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
Flag reading moved The flag server now returns nothing at all, having stopped carrying it for tengu_haze_glass, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
