1. Architectural Blueprint (Current State)

The project consists of three core components:

2. Core Strengths & Completed Milestones (V1)

Reviewing PLAN.md shows that the core of Phase 1 (V1) is highly functional:

• Intelligent Sessionizer: db.py groups consecutive terminal commands into distinct logical sessions anchored around the inferred project_root (resolving .git, Cargo.toml, etc.) and a configurable time gap (e.g., 20 minutes).
• Failure-Recovery Tracking: The system detects a failing command (exit code $\neq 0$), captures its likely_root_cause via stdout heuristics, and automatically registers a recovery link (failure_fixes table) when the same command subsequently succeeds.
• Hybrid Recall & Synthesis: /v1/recall combines semantic vectors from Qdrant with classic SQLite LIKE fallbacks, feeding relevant context to the Gemini generative model to write a clean natural language answer to questions like tm recall "why did docker fail last time?".
• Weekly Reporting: Automatic aggregation of category stats, failure rates, and recurring failure commands.

3. Discovered Gaps & Technical Opportunities

A. The Capture Daemon is Missing Shell Hooks

Important

The largest architectural gap is the lack of automated shell interception. Right now, commands must be manually ingested via tm ingest or daemon. Passive observation (the primary value proposition of Terminux) is not yet active.

B. Regex Classifier Ambiguity & False Positives

tests/test_classifier.py contains documented edge cases of the regex classifier:

• compose alone matches container (e.g. compose an email is classified as container).
• uv alone matches python-dev (e.g. check uv levels matches python-dev).
• token matches auth anywhere in a command or output (e.g., echo token_name becomes auth).

C. Secret Redaction Completeness

Though we have 8 strong regex patterns (IPs, AWS keys, JWTs, database strings), we don't yet capture:

• Private SSH keys (-----BEGIN OPENSSH PRIVATE KEY-----).
• Slack/Discord webhook URLs.
• Generic config values matching password = ... with multiline blocks.

D. User Feedback Loop for Corrections (V1.5 Goal)

The system classifies events automatically, but has no command for the user to override or correct a misclassification (e.g. fixing a compose an email event to be general instead of container).

4. Proposed Next Steps Plan

To systematically advance Terminux, we suggest prioritizing the roadmap into three distinct phases:

Phase A: Shell Hooking & Automation (Highly Recommended Immediate Step)

1. Develop Shell Hooks: Write shell scripts (for Bash/Zsh) that leverage shell hooks (PROMPT_COMMAND in Bash, preexec/precmd in Zsh) to capture commands, execution duration, and exit codes.
2. Daemon Enhancement: Update the Rust daemon to passively receive background signals from these shell hooks, tail the terminal output buffers, and automatically post the details asynchronously to the FastAPI backend.

Phase B: Strengthen Classifier & Secret Redaction (Low-Hanging Fruit)

1. Refine Classifier Regular Expressions:
   • Upgrade classifier.py to use stricter word boundaries (e.g., \buv\b is good, but check surrounding tokens to ensure it isn't uv index or uv rays).
   • Add negative lookaheads/lookbehinds to category matching.
2. Expand Redaction Patterns: Add SSH key headers and webhooks, and cover common config patterns to guarantee local-first safety.

Phase C: Implementing User Feedback Loop & Memory Correction (V1.5 Milestones)

1. API Support for Memory Correction: Add a /v1/events/{id}/correction endpoint to update database records and Qdrant payloads with corrected categories or root causes.
2. CLI Integration: Implement tm correct <event_id> --category <new_category> to easily fix any automated misclassifications.
3. Confidence Scoring: Add a lightweight confidence model/heuristics rating to inferred root causes (e.g., confidence: High for exact matching errors like ModuleNotFoundError).
