plan-history site rune — tag definition and pipeline hooks

Implement the plan-history Markdoc tag as a self-closing aggregation rune following the established plan rune pattern (sentinel + meta tags + placeholder → aggregate → postProcess resolution). Supports both per-entity and global feed modes.

Acceptance Criteria

  • Tag definition in runes/plan/src/tags/plan-history.ts with attributes: id, limit, type, since, group
  • Self-closing tag stores parameters as meta tags and emits sentinel marker
  • Rune config added to runes/plan/src/config.ts with block name plan-history
  • Rune exported in runes/plan/src/index.ts RunePackage
  • Aggregate hook extracts history data and adds to PlanAggregatedData
  • PostProcess hook detects sentinel and resolves per-entity timeline HTML
  • PostProcess hook detects sentinel and resolves global commit-grouped feed HTML
  • Per-entity HTML follows BEM structure from spec: rf-plan-history__events, __event, __date, __hash, __changes, __change, __field, __value, __criteria
  • Global feed HTML includes rf-plan-history--global modifier and __commit-message, __entity-summary elements
  • Attribute values use data-type="add|remove" for diff styling
  • Criteria collapse: show first 3, collapse rest with "+N more criteria" in per-entity mode
  • Auto-injection: postProcess appends History section to entity pages (when enabled) for entities with >1 commit
  • Commit hashes link to repository URL when configured (parsed from git remote get-url origin)

Dependencies

Approach

Follow the exact pattern used by plan-activity and plan-progress:

  1. Tag definition exports sentinel constant and uses createContentModelSchema with selfClosing: true
  2. Extend PlanAggregatedData interface with history: Map<string, HistoryEvent[]> and globalHistory fields
  3. In aggregate hook, run batch extraction and populate history data
  4. In postProcess, detect plan-history sentinel, read params, build timeline HTML using Markdoc Tag objects
  5. Auto-injection follows the same pattern as the existing auto-relationships injection

Repository URL parsing: use git remote get-url origin at aggregate time, with a config override field.

What was done

  • runes/plan/src/history.ts — Core event model types (HistoryEvent, AttributeChange, CriteriaChange) + per-entity extraction algorithm (git log --follow, git show, parse/diff) + batch extraction + caching
  • runes/plan/src/commands/history.ts — CLI plan history command with single-entity and global modes, all filters (--since, --type, --author, --status, --all, --limit, --format json)
  • runes/plan/src/cli-plugin.ts — Registered history command in CLI plugin
  • runes/plan/src/tags/plan-history.ts — Self-closing plan-history tag definition with sentinel pattern
  • runes/plan/src/pipeline.ts — Extended PlanAggregatedData with history + repositoryUrl fields, added aggregate hook extraction, added postProcess resolver for per-entity timeline and global commit-grouped feed
  • runes/plan/src/commands/render-pipeline.ts — Pass plan directory to pipeline via setPlanDir
  • runes/plan/src/config.ts — Added PlanHistory rune config
  • runes/plan/src/index.ts — Exported plan-history rune in RunePackage
  • runes/plan/styles/default.css — Timeline CSS with vertical line, circle markers, diff coloring, responsive layout
  • runes/plan/test/history.test.ts — 31 tests covering parsing, diffing, and integration with real git repos

Notes

  • All 6 work items were implemented together as they form a cohesive feature
  • Pre-existing build issues in the plan package (missing @types/node, unresolved @refrakt-md/runes) prevent full tsc build, but all new code compiles and tests pass via vitest
  • History cache uses a separate .plan-history-cache.json file (not merged into .plan-cache.json) to keep concerns separate
