The plan revision limit 5 is not reached though made more than 5 revisions to todo plan in with planner & builder agents

The plan revision limit of 5 is not being enforced. During this session, the planner and builder agents made more than 5 revisions to the todo plan (the plan went through versions v1 through v7, with multiple structural reorganizations from 3 steps → 15 sub-steps → 2 phases → 4 phases → 2 phases → 3 phases detailed → revision tracking). The limit was never triggered or warned about despite clearly exceeding 5 revisions.

Below is the full conversation revision log documenting all 34 revision interactions:

## Revision Timeline

## Sub-step Revision Heat Map

| Times Revised | Sub-steps |
|--------------|-----------|
| **3 revisions** | 2.2 `stg_customers`, 2.5 `dim_customers`, 3.6 Column docs, 3.7 Validation pipeline |
| **2 revisions** | 1.4 Sources, 2.1 `stg_events` |
| **1 revision** | 1.3 Packages, 3.3 `fct_events` tests, 3.4 `dim_customers` tests, 3.5 Cardinality test |
| **0 revisions** | 1.1 `dbt_project.yml`, 1.2 `profiles.yml`, 2.3 `snp_customers`, 2.4 `fct_events`, 3.1 `stg_events` tests, 3.2 `stg_customers` tests |

> **Most volatile**: `dim_customers.sql` — evolved from simple table → SCD1 with enrichment → SCD2 with snapshot + surrogate key + explicit columns across 3 major rewrites.
>
> **Most stable**: `fct_events.sql` — the original migration request, unchanged since the first prompt.
