… subsystem. - Creates a 400+ line QA journal entry in `.quality_assurance/` detailing missing edge cases for the `Decomposer` subsystem (`internal/campaign/decomposer.go`), categorized by Null/Empty, Type Coercion, User Request Extremes, and State Conflicts. - Inserts `// TODO: TEST_GAP` comments into `internal/campaign/decomposer_test.go` corresponding to the identified vulnerabilities. - Highlights architectural limits for parsing large monorepos directly into RAM versus streaming.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Narrow TODOs to uncovered subcases to avoid stale test-gap markers.
Several TODOs overlap tests already present in this file (e.g., empty source paths, JSON coercion paths, nil intelligence handling, deleted-file behavior). Please rewrite these as precise missing subcases instead of broad gaps, so the backlog reflects true coverage holes.

Adds QA analysis and test gap markers for the
Decomposersubsystem.This fulfills the request to act as a QA Automation Engineer. It selects
internal/campaign/decomposer.goand conducts a boundary value analysis on it. I created a >400 line report documenting potential failure modes such as OOM crashes on massive directories, nil pointer dereferences from concurrent setter modifications, Time-of-Check to Time-of-Use bugs, and Mangle string/atom type coercion issues. I also added explicit// TODO:comments to the test file for each identified gap.PR created automatically by Jules for task 1132844210941012876 started by @theRebelliousNerd
