 Supersedes the scanning constraint in [ADR-0006](0006-flat-vault-structure.md) which limited vault indexing to root-level `.md` files plus protected folders (`attachments/`, `assets/`).
 
 Users with folder-based workflows (PARA, Zettelkasten with folders, project directories) could not see or filter notes by directory. The vault scanner silently ignored all subdirectory `.md` files, making Laputa unsuitable for vaults with any folder structure.
 
 ## Decision
 
-**Extend the Rust vault scanner to index `.md` files in all visible subdirectories, and expose the vault's folder tree via a new `list_vault_folders` Tauri command so the sidebar can render a collapsible FOLDERS section.**

+
+## Context
+
+ADR-0014 (git-based vault cache) and ADR-0021 (push-to-main workflow) both assume the vault is a git repository, but neither codified it as a hard enforcement. In practice, opening a non-git folder silently degraded: the cache couldn't compute a commit hash, Pulse/Changes were empty, and commit/push commands failed. The failure mode was invisible to users.
+
+## Decision
+
+**When the app opens a vault that has no `.git` directory, a blocking modal prevents all app use until the user either initialises a git repository (git init + initial commit, offered as a one-click action) or selects a different vault. The check is performed by a new `is_git_repo` Tauri command. In browser/dev mode, the check fails open (modal is skipped).**
+
+## Options considered
+
+- **Option A** (chosen): Hard block via modal on vault open — unambiguous, prevents silent failures, surfaces the fix immediately. Downside: breaks existing workflows for users with non-git vaults; requires a clear escape hatch (choose different vault).
+- **Option B**: Soft warning banner, allow using the app without git — avoids blocking users, but silent failures persist for Pulse/Changes/commit features.
+- **Option C**: Auto-init git on vault open without asking — less friction, but surprising; user may not want their vault in git.
+
+## Consequences
+
+- Git is now a first-class prerequisite for Laputa vaults, not just implied by the cache strategy.
+- The `is_git_repo` command is intentionally lightweight (checks for `.git` existence only; does not validate remote or commit history).
+- The modal offers `git init` + an initial commit as a one-click path, lowering the barrier for new users.
+- Browser mode bypasses the check so dev/Storybook workflows are unaffected.
+- Re-evaluate if Laputa needs to support non-git vaults (e.g., iCloud-only, shared network drive); at that point ADR-0014 would also need revisiting.

+title: "Path-suffix wikilink resolution for subfolder vaults"
+status: active
+date: 2026-04-01
+---
+
+## Context
+
+ADR-0006 stated that wikilink resolution was "simplified to multi-pass title/filename matching — no path-based matching needed" because the vault was flat. ADR-0033 relaxed the flat-vault constraint by adding subfolder scanning. As a result, wikilinks like `[[docs/adr/0031-foo]]` or `[[adr/0031-foo]]` could not resolve to entries in subdirectories: the resolver only matched on `title` and `filename` stem, never on the vault-relative path.
+
+The backlink detection in the Inspector also used a hardcoded `/Laputa/` path regex, which was wrong for any vault that isn't named "Laputa".
+
+## Decision
+
+**Add path-suffix matching as Pass 1 of wikilink resolution: a link target resolves to a `VaultEntry` if the entry's vault-relative path ends with the link string (with or without `.md`). Filename-stem matching (the previous Pass 1) becomes Pass 2. Inspector backlinks replace the hardcoded `/Laputa/` regex with a generic `targetMatchesEntry` path-suffix helper. Autocomplete pre-filter also matches against the full vault-relative path so subfolder names surface results.**
+
+## Options considered
+
+- **Option A** (chosen): Path-suffix as Pass 1, then filename match as Pass 2 — consistent with how Obsidian resolves links in multi-folder vaults, zero config. Downside: if two notes share the same filename in different folders, only the first (path-suffix) match wins.
+- **Option B**: Strict full-path matching only (disable title-stem resolution) — unambiguous, but breaks the majority of existing short-form `[[note-title]]` links.
+- **Option C**: Keep title-only matching, require full paths for subfolder notes — backwards-compatible, but forces users to always type full paths for subfolders, defeating the purpose of wikilinks.
+
+## Consequences
+
+- Supersedes the "no path-based matching needed" clause from ADR-0006 (that assumption was contingent on the flat vault invariant, which ADR-0033 relaxed).
+- `relativePathStem` utility added in `wikilink.ts` to extract the vault-relative path stem from a full `VaultEntry`.
+- The Inspector's `targetMatchesEntry` helper is now the canonical way to test if a link resolves to an entry — use it everywhere instead of ad-hoc regex.
+- Wikilink autocomplete suggestions now surface notes in subfolders when users type a folder prefix (e.g. `[[adr/`).
+- Re-evaluate if path-suffix ambiguity (two files with the same name in different folders) becomes a user complaint.

+title: "External rename detection via git diff on focus regain"
+status: active
+date: 2026-04-01
+---
+
+## Context
+
+Laputa handles in-app renames (rename.rs) and propagates wikilink updates across the vault. But notes can also be renamed externally — from Finder, another editor, or a git operation (e.g., `git mv`). In those cases, the app had no way to detect that a rename had occurred, leaving wikilinks broken and the vault inconsistent.
+
+The app already uses git for the cache (ADR-0014) and requires git as a vault prerequisite (ADR-0034), making git diff a natural and already-available detection mechanism.
+
+## Decision
+
+**When the app window regains focus, run `git diff --diff-filter=R --name-status HEAD` to detect file renames that occurred since the last committed HEAD. If any renamed `.md` files are found, show a non-blocking banner ("X file(s) renamed — update wikilinks?"). Accepting triggers the existing vault-wide wikilink replacement logic (reused from rename.rs). Ignoring dismisses the banner without changes. New Tauri commands: `detect_renames` and `update_wikilinks_for_renames`.**
+
+## Options considered
+
+- **Option A** (chosen): Git diff on focus regain, non-blocking banner — uses existing infrastructure, non-disruptive, user retains control. Downside: only detects renames that are staged/committed; uncommitted renames via `git mv` are captured, but renames done purely in Finder (no git involvement) are not.
+- **Option B**: `FSEvents` / file-system watcher for rename events — catches all renames regardless of git. Downside: significantly more complex, requires Rust async machinery, false positives from editor temp files, and this feature is already planned as a separate enhancement.
+- **Option C**: Scan for broken wikilinks on focus — correct but O(n) and noisy; doesn't tell us the new filename.
+
+## Consequences
+
+- Git's rename detection (`--diff-filter=R`) requires the rename to be git-tracked (either staged or committed); renames that happen outside git knowledge are not detected by this mechanism.
+- The on-focus check runs `git diff HEAD` which is fast but adds a small shell invocation overhead each time the window activates. This is acceptable for typical vault sizes.
+- `rename.rs` is now shared between in-app renames and external rename recovery — the replacement logic is the canonical entry point for wikilink bulk updates.
+- The banner is non-blocking and "Ignore" is always available — the user never loses work.
+- Re-evaluate if FS-level rename detection (outside git) becomes a priority; at that point this mechanism would be a fallback, not the primary strategy.

+title: "Language-based markdown syntax highlighting in raw editor"
+status: active
+date: 2026-04-01
+---
+
+## Context
+
+The raw editor (CodeMirror 6, introduced in ADR-0022) initially had a custom `frontmatterHighlight` extension that used regex-based decoration for YAML frontmatter and headings. Markdown body content had no syntax highlighting at all, making the raw editor feel like a plain textarea despite being a full CodeMirror instance.
+
+Extending the custom regex-based approach to cover all markdown syntax (bold, italic, links, lists, blockquotes, code) would have been brittle and hard to maintain.
+
+## Decision
+
+**Replace the custom heading decoration in `frontmatterHighlight.ts` with `@codemirror/lang-markdown` (the official CodeMirror language package). A custom `HighlightStyle` maps CodeMirror highlight tags to visual styles for headings, bold, italic, strikethrough, links, lists, blockquotes, and inline code. The frontmatter YAML plugin is retained for YAML-specific colouring but its heading decoration is removed in favour of the language parser.**
+
+## Options considered
+
+- **Option A** (chosen): `@codemirror/lang-markdown` with custom HighlightStyle — uses the official, maintained language parser; future highlight rules are one CSS declaration. Downside: adds a new npm dependency; the custom frontmatter plugin must be kept separately.
+- **Option B**: Extend the custom regex plugin to cover all markdown — no new dependency. Downside: regex-based tokenisation is fragile (e.g., nested formatting), already proving hard to maintain after the heading/frontmatter overlap bug.
+- **Option C**: Switch to a markdown-aware editor (e.g., Milkdown, Monaco) — full-featured. Downside: major migration, breaks the dual-editor architecture in ADR-0022, significant scope.
+
+## Consequences
+
+- `@codemirror/lang-markdown` added to `package.json` — this is the only new runtime dependency introduced by this change.
+- `frontmatterHighlight.ts` is simplified (heading decoration removed); `markdownHighlight.ts` is the new extension responsible for body highlighting.
+- The two extensions are composed in `useCodeMirror.ts` — YAML frontmatter block is still styled by the custom plugin; everything else by the language parser.
+- Future syntax highlighting changes (e.g., task lists, tables) can be added by extending the `HighlightStyle` without modifying the parser.
+- Re-evaluate if `@codemirror/lang-markdown` conflicts with the custom frontmatter YAML handling as the editor evolves (e.g., if frontmatter block needs to be parsed as a code block rather than decorated text).
