+Deterministic phase offsets for the proxy's scheduled background jobs.
+
+APScheduler anchors an ``interval`` job at ``now + interval``, so every job registered in
+the same startup shares one firing instant for the life of the process, and every replica
+brought up by the same rollout shares it too. The result is a burst: each tick, every job
+on every replica queries Postgres at the same moment, competing with the request path for
+the connection pool. The product's own daily/monthly crons are worse still, since they name
+a wall-clock instant that is identical on every replica by construction.
+
+The fix is a phase offset derived from ``sha256(job_id, identity)``, where ``identity``
+covers the pod and the worker process. Different jobs get different offsets, different
+replicas get different offsets for the same job, and nothing collapses back onto a shared
+instant after a restart. Hashing rather than randomising keeps a given process's schedule
+stable for its whole life and lets the applied offsets be logged once and reasoned about
+later.
+
+The offset lives in the trigger rather than in a one-off ``next_run_time`` because a cron
+trigger recomputes each fire from the wall clock and would otherwise snap straight back
+onto the shared instant after its first shifted run.
+
+Only schedules LiteLLM itself chose are shifted. Interval jobs are always eligible; cron
+jobs only when their id is one of the product's own defaults, so an operator-supplied
+crontab keeps the exact instant it asks for. A job whose call site passed an explicit
+``next_run_time`` already anchors itself and is left alone.

-        REAL-WORLD PROXY SERVER CONFIGURATION EXAMPLE:
-        ===============================================
-        
-        In a proxy_server_config.yaml file, you would define:
-        
-        model_list:
-          - model_name: bedrock-claude-3-haiku
-            litellm_params:

-        FUNCTION CALLING WITH PROXY SERVER:
-        ===================================
-        
-        When using the proxy server with this configuration:
-        
-        1. Client calls: supports_function_calling("bedrock-claude-3-haiku")
-        2. Proxy server resolves to: bedrock/converse/anthropic.claude-3-haiku-20240307-v1:0
-        3. LiteLLM evaluates the underlying model's capabilities
-        4. Returns: True (because Claude 3 Haiku supports function calling)
-        
-        Without the proxy server configuration context, LiteLLM cannot resolve
-        the custom model name and returns False.

-        ===============================================
-        
-        In a proxy_server_config.yaml file, you would define:
-        
-        model_list:
-          - model_name: bedrock-claude-3-haiku
-            litellm_params:

-        FUNCTION CALLING WITH PROXY SERVER:
-        ===================================
-        
-        When using the proxy server with this configuration:
-        
-        1. Client calls: supports_function_calling("bedrock-claude-3-haiku")
-        2. Proxy server resolves to: bedrock/converse/anthropic.claude-3-haiku-20240307-v1:0
-        3. LiteLLM evaluates the underlying model's capabilities
-        4. Returns: True (because Claude 3 Haiku supports function calling)
-        
-        Without the proxy server configuration context, LiteLLM cannot resolve
-        the custom model name and returns False.
