+Quartz supports [Obsidian Bases](https://help.obsidian.md/bases), which allow you to create dynamic, database-like views of your notes. See the [official Obsidian documentation](https://help.obsidian.md/bases/syntax) for the full syntax reference.
+
+## Quick Example
+
+Create a `.base` file in your content folder:
+
+```yaml
+filters:
+  and:
+    - file.hasTag("task")
+
+views:
+  - type: table
+    name: "Task List"
+    order:
+      - file.name
+      - status
+      - due_date
+```
+
+Each view gets its own page at `<base-name>/<view-name>`.
+
+## Wikilinks
+
+Link to base views using the standard [[navigation.base#Plugins|wikilink]] syntax:
+
+```markdown
+[[my-base.base#Task List]]
+```
+
+This resolves to `my-base/Task-List`.
+
+## Configuration
+
+This functionality is provided by the [[ObsidianBases]] transformer plugin (which parses `.base` files) and the [[BasePage]] emitter plugin (which generates the pages).

+# bases compiler + runtime (quartz implementation)
+
+status: active
+last updated: 2026-01-28
+
+this directory contains the obsidian bases compiler, interpreter, and runtime helpers used by quartz to render `.base` files. it is designed to match obsidian bases syntax and semantics with deterministic evaluation and consistent diagnostics.
+
+You can test it out with any of the base file in my vault here:
+
+```bash
+npx tsx quartz/util/base/inspect-base.ts docs/navigation.base > /tmp/ast-ir.json
+
+jq '.expressions[] | {context, kind, source, ast}' /tmp/ast-ir.json
+jq '.expressions[] | {context, kind, ir}' /tmp/ast-ir.json
+```
+
+## scope
+
+- parse base expressions (filters, formulas, summaries, property expressions)
+- compile expressions to bytecode ir
+- interpret bytecode with a deterministic stack vm
+- resolve file, note, formula, and property values
+- render views (table, list, cards/gallery, board, calendar, map)
+- surface parse and runtime diagnostics in base output
+
+## architecture (pipeline)
+
+1. parse `.base` yaml (plugin: `quartz/plugins/transformers/bases.ts`)
+2. parse expressions into ast (`compiler/parser.ts`)
+3. compile ast to ir (`compiler/ir.ts`)
+4. evaluate ir per row with caches (`compiler/interpreter.ts`)
+5. render views and diagnostics (`render.ts`)
+
+## modules
+
+- `compiler/lexer.ts`: tokenizer with span tracking and regex support
+- `compiler/parser.ts`: pratt parser for expression grammar and error recovery
+- `compiler/ir.ts`: bytecode instruction set + compiler
+- `compiler/interpreter.ts`: stack vm, value model, coercions, methods, functions
+- `compiler/diagnostics.ts`: diagnostics types and helpers
+- `compiler/schema.ts`: summary config schema and builtins
+- `compiler/properties.ts`: property expression builder for columns and config keys
+- `render.ts`: view rendering and diagnostics output
+- `query.ts`: summaries and view summary helpers
+- `types.ts`: base config types and yaml parsing helpers
+
+## value model (runtime)
+
+runtime values are tagged unions with explicit kinds:
+
+- null, boolean, number, string
+- date, duration
+- list, object
+- file, link
+- regex, html, icon, image
+
+coercions are permissive to match obsidian behavior. comparisons prefer type-aware equality (links resolve to files when possible, dates compare by time, etc), with fallbacks when resolution fails.
+
+## expression features (spec parity)
+
+- operators: `==`, `!=`, `>`, `<`, `>=`, `<=`, `&&`, `||`, `!`, `+`, `-`, `*`, `/`, `%`
+- member and index access
+- function calls and method calls
+- list literals and regex literals
+- `this` binding with embed-aware scoping
+- list helpers (`filter`, `map`, `reduce`) using implicit locals `value`, `index`, `acc`
+- summary context helpers: `values` (column values) and `rows` (row files)
+
+## diagnostics
+
+- parser diagnostics are collected with spans at compile time
+- runtime diagnostics are collected during evaluation and deduped per context
+- base views render diagnostics above the view output
+
+## this scoping
+
+- main base file: `this` resolves to the base file
+- embedded base: `this` resolves to the embedding file
+- row evaluation: `file` resolves to the row file
+
+## performance decisions
+
+- bytecode ir keeps evaluation linear and stable
+- per-build backlink index avoids n^2 scans
+- property cache memoizes property expressions per file
+- formula cache memoizes formula evaluation per file
+
+## view rendering
+
+- table, list, cards/gallery, board, calendar, map
+- map rendering expects coordinates `[lat, lon]` and map config fields
+- view filters combine with base filters via logical and
