Fire up the Observer

USER GOAL:

Working Directory

STEPS:

Step 1: Audit the Metadata

1. Read the rest of this file for the context window.
2. Systematically audit the metadata of each file within the content/lost-in-public/issue-resolution directory. For each file: a. Parse its frontmatter. b. Compare its structure against the expected pattern for 'Issue Resolution' items (refer to the tidyverse/observers/templates/issue-resolution.ts template for the expected structure and the "Ideal Data Example for Issue Resolution" section below). c. Log any identified inconsistencies, errors, or missing mandatory fields. Proceed through all files without requiring intermediate confirmation for each.

Step 2: Understand the Patterns and Architecture of the Observer and Watcher System

1. Read the other watcher files in tidyverse/observers/watchers to understand the pattern, including the imported handlers, utils and services.
2. Read the master orchestration in tidyverse/observers/index.ts, tidyverse/observers/userOptionsConfig.ts, and tidyverse/observers/fileSystemObserver.ts to understand the pattern, including separation of concerns, DRY principles, and the use of the propertyCollector.
3. Read the starter files previously created in tidyverse/observers/templates/issue-resolution.ts
4. Visualize the Flow: The following diagram illustrates how the new issueResolutionWatcher.ts will integrate into the existing observer system:
   graph TD subgraph IssueResolutionWatcher Integration A[File Event in 'content/lost-in-public/issue-resolution'] --> B(FileSystemObserver); B --> C{PropertyCollector Check}; C --> D[issueResolutionWatcher.ts]; D --> E[Read 'issue-resolution.ts' Template]; D --> F[Process Frontmatter (yamlFrontmatter.ts)]; F --> G[Apply Handlers (e.g., addSiteUUID.ts)]; G --> H[Write Updated File]; end
5. Understand the Target Data Structure (Ideal Data Example for Issue Resolution): The goal of the watcher is to ensure that frontmatter for 'Issue Resolution' items is consistent and complete. Here's an example of an ideal, fully processed frontmatter for an item in the content/lost-in-public/issue-resolution directory:
   yaml

   ---
   title: 'Specific Issue Title'
   lede: 'Short description of the issue and its resolution.'
   status: 'Resolved' # Expected values: 'Reported', 'Investigating', 'Pending-Fix', 'Resolved', 'Wont-Fix'
   date_reported: YYYY-MM-DD
   date_resolved: YYYY-MM-DD # (nullable if not resolved)
   affected_systems: ['System A', 'Module B'] # (array of strings, optional)
   severity: 'Medium' # Expected values: 'Low', 'Medium', 'High', 'Critical' (optional)
   resolution_summary: 'Key steps taken to resolve the issue, or current status.'
   tags: ['bug-fix', 'database', 'specific-module'] # (standard tags)
   site_uuid: 'auto-generated-uuid-12345' # (auto-generated by addSiteUUID.ts handler)
   # Add any other fields defined in tidyverse/observers/templates/issue-resolution.ts
   ---

   Refer to tidyverse/observers/templates/issue-resolution.ts for the canonical template definition.
6. Suggest the best way to implement a watcher for the issue resolution collection.

Step 3: Implement the Plan

1. Define Key Characteristics for issueResolutionWatcher.ts: Before coding, clarify the following for the new watcher:
   • Input:
     • filePath: string (absolute path to the changed file)
     • fileContent: string (content of the file)
     • frontmatter: object (parsed frontmatter from the file)
     • dirConfig: object (the specific configuration for the 'issue-resolution' directory from userOptionsConfig.ts)
   • Primary Logic:
     • Validate and conform frontmatter against tidyverse/observers/templates/issue-resolution.ts.
     • Apply relevant handlers (e.g., addSiteUUID.ts, and potentially others specific to issue resolution if needed).
   • Output:
     • Object containing the updatedFrontmatter (object) and updatedFileContent (string) if changes were made.
     • Return null or an equivalent indicator if no changes are necessary.
   • Side Effects:
     • Logs its processing activity clearly.
     • Interacts with the propertyCollector to register expected changes and prevent loops.
2. Implement the plan.
3. Test the implementation focused on the "issue resolution" collection subsystem on the content/lost-in-public/issue-resolution directory.
4. Run all the subsystems at once to see if they work together.

The Observer System

Previous Mistakes:

• Infinite Loops: The observer was triggering itself, leading to an infinite loop. This was resolved by adding a universal "propertyCollector" in the main observer, which then delegates all tasks to the appropriate watchers, handlers, services, and utils. The propertyCollector immediately receives an "expectation" object, which is a list of properties that will be created or modified by the watchers, handlers, services, and utils. The propertyCollector also includes a cooldown period and an in-memory log of files that have been processed.
• Random Frontmatter Corruption: When introducing new functionality to the observer system, functionality that had already been honed and was error free would be duplicated for convenience of Code Generation and reasoning within one file. But, the use of regular expressions and text manipulation to extract, evaluate, generate and update frontmatter created inconsistencies, and sometimes glaring errors that corrupted entire directories of content, which then needed to be fixed. We have MAINLY solved for this by using DRY principles and keeping extraction, evaluation, and update logic in a single-source-of-truth that is used by all watchers, handlers, services, and utils. IT IS CRITICAL TO FOLLOW THIS PRINCIPLE AND NOT UNNECESSARILY DUPLICATE FRONTMATTER TRANSFORMATION LOGIC ACROSS FILES.

Running the Observer

cd /Users/mpstaton/code/lossless-monorepo/tidyverse
pnpm start

pnpm start -- ../../content

1. Start the FileSystemObserver
2. Watch for file changes in configured directories
3. Process citations in markdown files (convert numeric to hex)
4. Validate and update frontmatter
5. Generate reports periodically

How Watchers Work:

1. Configuration and Initialization:
   • Watcher configurations are primarily managed in tidyverse/observers/userOptionsConfig.ts. This file defines which directories (collections) are actively monitored by the system.
   • The master orchestration script, tidyverse/observers/index.ts, initiates the FileSystemObserver (detailed in tidyverse/observers/fileSystemObserver.ts).
   • The FileSystemObserver iterates through the directoryConfigs from userOptionsConfig.ts. For each configured directory, it sets up a dedicated file system watcher instance (typically using a library like chokidar).
   • Each watcher is responsible for a specific content collection path (e.g., content/lost-in-public/prompts, content/tooling).
2. Event Detection:
   • Watchers are set to listen for file system events, primarily:
     • add: When a new file is created in a watched directory.
     • change: When an existing file is modified in a watched directory.
   • The FileSystemObserver includes a "propertyCollector" mechanism. This component is crucial for:
     • Receiving an "expectation" object, which lists properties that will be created or modified by downstream processes (handlers, services).
     • Managing a cooldown period.
     • Maintaining an in-memory log of processed files to prevent infinite loops and redundant operations.
3. Processing Workflow (per file event):
   • When a file event (add/change) occurs, the FileSystemObserver's onChange (or similar) method is triggered, receiving the dirConfig for the specific file.
   • The system first consults the propertyCollector to ensure the file is eligible for processing.
   • The task is then delegated to the appropriate processing pipeline, which involves a series of steps tailored to the collection:
   a. Citation Processing (Conditional): * If applicable to the collection and enabled, citations within the markdown file are processed (e.g., converting numeric citations to hex format) using methods like processCitationsInFile.
   b. Frontmatter Processing: This is a core function involving multiple sub-steps: * Extraction: The existing YAML frontmatter is read from the file using utilities like tidyverse/observers/utils/yamlFrontmatter.ts. * Validation & Templating: The extracted frontmatter is validated against a predefined template specific to the collection (e.g., tidyverse/observers/templates/issue-resolution.ts for the issue resolution collection). This step ensures consistency and completeness. * Applying Handlers: A set of handlers from tidyverse/observers/handlers/ are invoked to modify or add frontmatter properties. Common handlers include: * addSiteUUID.ts: Ensures every content piece has a unique site_uuid. * Specialized handlers like processOpenGraphMetadata.ts or processScreenshotMetadata.ts may be used for specific collections (like 'tooling') that require integration with services (tidyverse/observers/services/). * Normalization & Enrichment: Property names are normalized, and missing required fields (as defined by the template) are added. * Updating: The modified frontmatter is written back to the file using tidyverse/observers/utils/yamlFrontmatter.ts.
4. Logging and Reporting:
   • Throughout the process, detailed logs are output to the console, indicating files being processed, specific actions taken (e.g., citations converted, frontmatter updated), and any errors or warnings encountered.
   • The system may also generate periodic reports summarizing its activity.

How Citation Processing Works

1. Converts Numeric Citations: Identifies numeric citations within the content and converts them to a standardized format (e.g., hexadecimal).
2. Updates Citation Registry: Maintains a registry or database of all citations encountered, ensuring consistency and enabling features like a master bibliography.
3. Generates Footnotes: If the citation style requires it, this step automatically creates or updates a footnotes section at the end of the document.

Monitoring Results

• Files being processed
• Citations being converted
• Frontmatter being updated
