* doc: introduce mental models blog post
Write blog post introducing Mental Models in Hindsight 0.4.0:
- Evolution from observations and opinions
- How mental models work (consolidation, evidence tracking)
- Breaking changes and migration path
- Environment variable to enable (experimental)
- Agentic reflect explanation
* updates
* Update 2026-01-26-learning-capabilities.md
* fix: doc build issues
- Add missing code snippets for versioned docs (recall-opinions-only, recall-include-entities, bank-background)
- Fix broken links by using relative paths for version compatibility
- Update blog post title to sentence case
- Clear versions.json since v0.3 versioned docs don't exist yet
- Enable INCLUDE_CURRENT_VERSION in build script
* fix: update doc links after rebase
- Fix blog post to link to correct pages (/developer/api/mental-models and /developer/observations)
- Fix CLI docs to link to /api-reference instead of /api
* feat: add directives section to blog post
- Update intro to mention three layers of knowledge
- Add concise Directives section for compliance/guardrails
- Add directives to resources section
- Keep focus on learning capabilities (observations and mental models)
* fix: revert intro to focus on learning capabilities only
Directives are a separate feature for compliance/guardrails, not a learning capability. The blog post is about observations and mental models.
* fix: misc fixes for observations and mental models
* feat: improve graph retrieval for observations
- Update LinkExpansionRetriever to traverse through source_memory_ids
for observation entity connections (avoiding data duplication)
- Remove entity link copy from world facts to observations in consolidator
- Add tests for link expansion graph retrieval
- Add directives_applied field to ReflectResult
- Include user's other changes (CLI, docs, client updates)
* fix: CI test failures
- Add mental_model_id parameter to create_mental_model function
- Fix ToolCallTrace not including reason field from ToolCall
- Improve test_link_expansion_observation_graph_retrieval to wait for consolidation with retry
* chore: reduce link expansion log verbosity
* Revert "chore: reduce link expansion log verbosity"
This reverts commit 3ce759391cead1012157785fa78fef16ef9bfe3b.
* feat: add semantic/temporal/entity links as fallback in graph retrieval
- Add fallback query for semantic, temporal, and entity links from memory_links
- Check both directions (outgoing and incoming links)
- Weight fallback results at 0.5x to prioritize entity links via unit_entities
- Fixes graph retrieval returning 0 when data has cross-cluster temporal connections
* fix: enable observations fixture for link expansion test
- Add enable_observations fixture to ensure observations are created
- Increase wait time from 10 to 30 seconds for CI reliability
* bump pg0 0.11.x and improve documentation
* bump pg0 0.11.x and improve documentation

Update url and baseUrl for hindsight.vectorize.io custom domain.
With custom domains, GitHub Pages serves from root path instead of
project subdirectory.
