+# Cassie Functions - Example Usage Scripts
+
+This directory contains minimal example scripts demonstrating how to call each function that was migrated from `pycassa` to the `cassandra` ORM in `src/errors/cassie.py`.
+
+## Purpose
+
+These scripts provide:
+- Clear examples of function signatures and parameters
+- Sample input data for each function
+- Basic usage patterns
+
+## Important Notes
+
+⚠️ **These are example scripts only** - They demonstrate the API but won't run successfully without:
+- A properly configured Cassandra database connection
+- Valid data in the database
+- Required dependencies installed (cassandra-driver, numpy, etc.)
+
+## Structure
+
+Each file corresponds to one function in `cassie.py`:
+- `get_total_buckets_by_day.py` - Example for `get_total_buckets_by_day()`
+- `get_bucket_counts.py` - Example for `get_bucket_counts()`
+- `get_crashes_for_bucket.py` - Example for `get_crashes_for_bucket()`
+- And so on...
+
+## Usage
+
+To understand how to use a specific function:
+
+1. Open the corresponding `.py` file
+2. Review the function call with example parameters
+3. Adapt the parameters to your use case
+
+Example:
+```bash
+# View the example (won't execute without DB connection)
+cat get_bucket_counts.py
+```
+
+## Functions Included
+
+All functions migrated from pycassa to cassandra ORM:
+
+### Bucket Operations
+- `get_total_buckets_by_day` - Get bucket counts by day
+- `get_bucket_counts` - Get bucket counts with filtering
+- `get_crashes_for_bucket` - Get crashes for a specific bucket
+- `get_package_for_bucket` - Get package info for bucket
+- `get_metadata_for_bucket` - Get metadata for bucket
+- `get_metadata_for_buckets` - Get metadata for multiple buckets
+- `get_versions_for_bucket` - Get versions for bucket
+- `get_source_package_for_bucket` - Get source package
+- `get_retrace_failure_for_bucket` - Get retrace failure info
+- `get_traceback_for_bucket` - Get traceback for bucket
+- `get_stacktrace_for_bucket` - Get stacktrace for bucket
+- `bucket_exists` - Check if bucket exists
+
+### Crash Operations
+- `get_crash` - Get crash details
+- `get_crash_count` - Get crash counts over time
+- `get_user_crashes` - Get crashes for a user
+- `get_average_crashes` - Get average crashes per user
+- `get_average_instances` - Get average instances for bucket
+
+### Package Operations
+- `get_package_crash_rate` - Analyze package crash rates
+- `get_package_new_buckets` - Get new buckets for package version
+- `get_binary_packages_for_user` - Get user's packages
+
+### Retracer Operations
+- `get_retracer_count` - Get retracer count for date
+- `get_retracer_counts` - Get retracer counts over time
+- `get_retracer_means` - Get mean retracing times
+
+### Bug/Signature Operations
+- `record_bug_for_bucket` - Record a bug for bucket
+- `get_signatures_for_bug` - Get signatures for bug
+- `get_problem_for_hash` - Get problem for hash
+
+### System Image Operations
+- `get_system_image_versions` - Get system image versions
+
+## Migration Notes
+
+These functions were migrated from the deprecated `pycassa` library to the modern `cassandra-driver` ORM while maintaining backward compatibility.

 ## Important Notes
 
 ⚠️ **These are example scripts only** - They demonstrate the API but won't run successfully without:
-- A properly configured Cassandra database connection
+- A properly configured Cassandra database connection (configured via `errortracker.config`)
 - Valid data in the database
 - Required dependencies installed (cassandra-driver, numpy, etc.)
 
+Each script includes a call to `setup_cassandra()` which initializes the Cassandra connection before using any functions. This function:
+- Sets up the database connection using credentials from the configuration
+- Synchronizes the database schema
+- Ensures the connection is ready for queries
+
 ## Structure
 
 Each file corresponds to one function in `cassie.py`:

a bit the testing of things, because the tests can now create crashes in
the past way more easily.

Subject: [PATCH 18/65] cassie: manual tests and fixes against production data

Here is a summary of the main changes I had to do after Copilot's work.

Over 27 functions, 17 were dead-simple and worked or almost worked out
of the box. However for the following 10 functions, way more work was
needed to make them work:
* get_crashes_for_bucket.py: that one was just plain wrong and was
  rewritten
* get_metadata_for_buckets.py: without being wrong, any human would have
  seen that it just needed to call the previous function in a loop
* get_package_crash_rate.py: without being completely wrong, this one
  had to be fixed, because the AI doesn't know about `.order_by()`
* get_package_new_buckets.py: that one did work, but had Copilot really
  confused about str vs bytes
* get_retracer_counts.py: this one had half of it looking really weird,
  but that was dead-code anyway, so it's gone
* get_retracer_means.py: this one was rewritten from scratch. Copilot
  guessed whatever it wanted, but the new API just doesn't work like the
  old one, and I had to use a completely different approach.
* get_signatures_for_bug.py: copilot confused again with typing of int
  vs str
* get_user_crashes.py: some weirdness around cassandra and timestamp,
  that obviously got Copilot confused
* get_versions_for_bucket.py: Copilot used the wrong columns and
  reported a valid but completely different result from what was expected
* record_bug_for_bucket.py: usual mess with the str vs bytes vs int typing

In overall, I'm not sure regarding time gained or lost with regard to
using Copilot. What's sure is that I've been able to directly focus on
the interesting topic, without bothering with the initial boilerplate
of setting up harnesses to call each function, and the initial API
migration. I'd say it was a pretty positive experience, despite maybe
not looking like so from the PR or commit log.

Subject: [PATCH 62/65] tests: cassie: make the rest of the Copilot tests
 useful

Writing this commit is what actually enabled the previous one with
all the 'cassie' fixes. Obviously Copilot couldn't catch all of those
mistakes or wrong API usage.

-# Cassie Functions - Example Usage Scripts
-
-This directory contains minimal example scripts demonstrating how to call each function that was migrated from `pycassa` to the `cassandra` ORM in `src/errors/cassie.py`.
-
-## Purpose
-
-These scripts provide:
-- Clear examples of function signatures and parameters
-- Sample input data for each function
-- Basic usage patterns
-
-## Important Notes
-
-⚠️ **These are example scripts only** - They demonstrate the API but won't run successfully without:
-- A properly configured Cassandra database connection (configured via `errortracker.config`)
-- Valid data in the database
-- Required dependencies installed (cassandra-driver, numpy, etc.)
-
-Each script includes a call to `setup_cassandra()` which initializes the Cassandra connection before using any functions. This function:
-- Sets up the database connection using credentials from the configuration
-- Synchronizes the database schema
-- Ensures the connection is ready for queries
-
-## Structure
-
-Each file corresponds to one function in `cassie.py`:
-- `get_total_buckets_by_day.py` - Example for `get_total_buckets_by_day()`
-- `get_bucket_counts.py` - Example for `get_bucket_counts()`
-- `get_crashes_for_bucket.py` - Example for `get_crashes_for_bucket()`
-- And so on...
-
-## Usage
-
-To understand how to use a specific function:
-
-1. Open the corresponding `.py` file
-2. Review the function call with example parameters
-3. Adapt the parameters to your use case
-
-Example:
-```bash
-# View the example (won't execute without DB connection)
-cat get_bucket_counts.py
-```
-
-## Functions Included
-
-All functions migrated from pycassa to cassandra ORM:
-
-### Bucket Operations
-- `get_total_buckets_by_day` - Get bucket counts by day
-- `get_bucket_counts` - Get bucket counts with filtering
-- `get_crashes_for_bucket` - Get crashes for a specific bucket
-- `get_package_for_bucket` - Get package info for bucket
-- `get_metadata_for_bucket` - Get metadata for bucket
-- `get_metadata_for_buckets` - Get metadata for multiple buckets
-- `get_versions_for_bucket` - Get versions for bucket
-- `get_source_package_for_bucket` - Get source package
-- `get_retrace_failure_for_bucket` - Get retrace failure info
-- `get_traceback_for_bucket` - Get traceback for bucket
-- `get_stacktrace_for_bucket` - Get stacktrace for bucket
-- `bucket_exists` - Check if bucket exists
-
-### Crash Operations
-- `get_crash` - Get crash details
-- `get_crash_count` - Get crash counts over time
-- `get_user_crashes` - Get crashes for a user
-- `get_average_crashes` - Get average crashes per user
-- `get_average_instances` - Get average instances for bucket
-
-### Package Operations
-- `get_package_crash_rate` - Analyze package crash rates
-- `get_package_new_buckets` - Get new buckets for package version
-- `get_binary_packages_for_user` - Get user's packages
-
-### Retracer Operations
-- `get_retracer_count` - Get retracer count for date
-- `get_retracer_counts` - Get retracer counts over time
-- `get_retracer_means` - Get mean retracing times
-
-### Bug/Signature Operations
-- `record_bug_for_bucket` - Record a bug for bucket
-- `get_signatures_for_bug` - Get signatures for bug
-- `get_problem_for_hash` - Get problem for hash
-
-### System Image Operations
-- `get_system_image_versions` - Get system image versions
-
-## Migration Notes
-
-These functions were migrated from the deprecated `pycassa` library to the modern `cassandra-driver` ORM while maintaining backward compatibility.
