Enhanced Filesystem Observer Specification and Content-Wide Registries

Summary

A new section, "DataStore/Registry Handling for Content-Wide Syntax (Draft Guidance)", was added to the specification [Create-a-Content-Registry-for-Markdown-Files.md]. This section outlines the rationale, principles, and implementation patterns for using persistent JSON registries to track unique content-wide syntax, such as citations, media links, embeds, and images.

Key Additions

  • Registry Rationale: Explained why registries are needed for deduplication, analytics, and extensibility.
  • General Principles: Documented single source of truth, schema-driven validation, atomicity, and idempotency.
  • Example Interfaces: Provided TypeScript interface examples for citation and media/image registries.
  • Service Pattern: Described singleton and atomic update patterns for registry services.
  • Implementation Checklist: Listed concrete steps for integrating registry-backed services into the observer pipeline.
  • Pseudocode: Added example update flow for registry maintenance.
  • Open Questions: Raised future-facing questions about batching, concurrency, and audit trails.

Impact

  • Establishes a clear, extensible foundation for all future registry-backed content observation (citations, media, etc.).
  • Enables robust, cross-file analytics and prevents data corruption or duplication.
  • Promotes best practices for atomic updates and error handling in content registries.

Next Steps

  • Refine this draft as the first registry-backed observer (e.g., citations) is stabilized.
  • Extend the guidance to cover new content types as needed.
  • Review open questions and iterate on the implementation pattern for concurrency and auditability.

Summary

The specification for the Filesystem Observer for Consistent Metadata in Markdown files was significantly updated to provide:
  • Clearer architectural diagrams and event flow
  • Stronger requirements for non-destructive, template-driven, and transparent automation
  • A robust, append-only reporting mechanism
  • Actionable feedback loops for both developers and content authors
  • Explicit guidance for atomic, idempotent updates and error handling

Key Changes

  • System Pillars: Now explicitly prohibits YAML libraries for frontmatter parsing, mandates custom parsers, and expands the definition of template-driven consistency.
  • Architecture Overview: Updated the mermaid diagram to reflect new detection and handling logic.
  • Reporting: Changed report file handling to be append-only, with period-based aggregation and manual bloat management.
  • Activity Log: Standardized Obsidian-style backlink syntax for file references in logs.
  • Implementation Guidance: Emphasized atomic, idempotent file writes, centralized user options, and modular content processors.
  • Error Handling: Requires all errors, warnings, and changes to be logged and never silently swallowed.
  • Open Questions: Added new questions about AI code assistant compliance, test suite generation, and guarantees against unintentional changes.

Impact

  • Ensures robust, auditable, and reversible automation for Markdown metadata management
  • Provides a clear foundation for extensibility, future registry-backed features, and safe developer collaboration
  • Strengthens trust and transparency in content automation workflows

Next Steps

  • Review with development and content teams for further feedback
  • Begin implementation of atomic reporting and template-driven processing
  • Continue to iterate on registry and test suite guidance
