+# nib
+
+Capture-first note system. Catch thoughts, todos, and events before they slip — from terminal or browser. Everything lives in a single SQLite file.
+
+nib uses a tiny grammar to extract structure from plain text. You type naturally, and nib figures out what it is: a thought, a todo with a due date, an event, a titled reference. Tags, descriptions, and time anchors are pulled out automatically. The body stays as markdown.
+
+When something proves useful, promote it to a card (snippet, template, checklist, decision, link) for quick reuse. Cards track usage and float to the top.
+
+## Install
+
+Requires Go 1.24+.
+
+```
+go build -o nib .
+```
+
+Data lives at `~/.nib/nib.db` by default. Override with `NIB_DB=/path/to/file.db`.
+
+## Quick start
+
+```bash
+# capture a thought
+nib "proxy_pass needs a trailing slash"
+
+# todo
+nib "- buy mass gainer @tomorrow #errands"
+
+# titled entry with description
+nib "|nginx proxy trick // always forget this #ops"
+
+# todo with a title
+nib "- |deploy staging // rebuild docker image #ops"
+
+# list recent entries
+nib ls
+
+# list by tag
+nib ls --tag ops
+
+# list a specific month
+nib ls --month 2026-05
+
+# terminal UI
+nib tui
+
+# start the web UI
+nib serve
+```
+
+Open `http://localhost:4444` for the browser interface.
+
+## Grammar
+
+The full grammar fits on an index card. Here's what matters:
+
+### Kind prefixes
+
+The first character decides what kind of entry you're creating.
+
+| Input | Kind | Example |
+|-------|------|---------|
+| bare text | thought | `just an idea` |
+| `- text` | todo | `- buy milk @tomorrow` |
+| `@time text` | event | `@friday 2pm lunch with alex` |
+| `!time text` | reminder | `!3pm call dentist` |
+
+The dash needs a space after it. `-deploy` is a thought, `- deploy` is a todo.
+
+### Titles and descriptions
+
+Give an entry a name with `|` at the start. Add a description with `//`.
+
+```
+|nginx proxy trick
+proxy_pass http://backend/;
+
+|deploy checklist // for staging #ops
+1. docker build
+2. docker push
+3. ssh prod && restart
+
+// quick reference for proxy config
+the actual body text goes here
+
+body text // this part becomes the description
+```
+
+Title shows as the scan label in list view. Description appears in the detail pane. Both are optional — most captures won't need them.
+
+### Tags and flags
+
+Tags and flags work anywhere in the input. They're extracted and removed from the body.
+
+```
+deploy nginx #ops #infra        → tags: ops, infra
+important thing !pin            → pinned to top
+use ##channel in slack          → literal #channel in body (escaped)
+```
+
+### Cards
+
+Promote a fluid entry to a card for reuse:
+
+```bash
+nib promote <id> snippet    # code trick, copy-to-clipboard
+nib promote <id> template   # has ${slots} to fill
+nib promote <id> checklist  # step-through items
+nib promote <id> decision   # chose/why/rejected
+nib promote <id> link       # URL with an open button
+```
+
+Or use `^type` inline: `nib "proxy trick #nginx ^card"`
+
+## CLI commands
+
+| Command | What it does |
+|---------|-------------|
+| `nib <input>` | Capture (shorthand for `nib add`) |
+| `nib ls` | List entries — filter with `--tag`, `--date`, `--month`, `--from`/`--to` |
+| `nib cards` | List cards sorted by usage |
+| `nib edit <id>` | Open in `$EDITOR` |
+| `nib copy <id>` | Copy body to clipboard |
+| `nib promote <id> [type]` | Promote to card |
+| `nib demote <id>` | Strip card, back to fluid |
+| `nib absorb <target> <source>` | Merge source into target |
+| `nib delete <id>` | Soft delete (repeat to hard delete) |
+| `nib serve` | Start web UI on `:4444` (or `--port`) |
+| `nib tui` | Launch the terminal UI |
+
+IDs are prefix-matchable. If `01KRQ4` is unique, that's enough.
+
+## Terminal UI
+
+`nib tui` launches a keyboard-driven interface in your terminal.
+
+- **Stream view** — entries grouped by date with compact gutter headers
+- **Cards view** — promoted cards filtered by intent (grab/read/fill), sorted by usage
+- **Split-pane detail** — wide terminals (100+ cols) show list and detail side-by-side
+- **Capture drawer** — inline add with live preview of parsed entity
+- **Search** — type `?query #tag` in the capture bar to filter
+
+Navigation: `j`/`k` move, `enter` opens detail, `h`/`l` switch panes, `a` to add, `?` for full keybindings.
+
+## Web UI
+
+`nib serve` starts a local web interface with:
+
+- **Capture bar** — same grammar as the CLI
+- **Stream view** — entries grouped by date, newest first
+- **Cards view** — promoted cards sorted by use count
+- **Tag rail** — filter by tag
+- **Month navigator** — browse by date range
+- **Detail pane** — full entry view, double-click to edit
+- **Keyboard shortcuts** — `j`/`k` navigate, `n` to capture, `p` to promote, `e` to edit, `dd` to delete
+
+Dark and light themes. Toggle with the button in the header.
+
+## Data
+
+Everything is one SQLite file. Back it up, sync it, move it between machines — it's just a file. WAL mode is on for concurrent reads.
+
+```bash
+# back up
+cp ~/.nib/nib.db ~/.nib/nib.db.bak
+
+# use a different database
+NIB_DB=/path/to/other.db nib ls
+```

+# Code Hardening — Senior Dev Audit Fixes
+
+## Phase 1: Quick Wins (safety + correctness)
+- [x] Cap API list limit at 200
+- [x] Fix markdown XSS — add DOMPurify to sanitize marked output
+- [x] Add missing DB indexes (deleted_at, modified_at) via v4 migration
+- [x] Fix v2 migration error handling (swallowed ALTER TABLE errors)
+- [x] Fix ~/.nib directory permissions (0o755 → 0o700)
+
+## Phase 2: CI Pipeline
+- [x] Gitea Actions workflow: test + lint on PR
+
+## Phase 3: context.Context in Store
+- [x] Thread context.Context through all Store methods
+- [x] Use context in API handlers (from r.Context())
+- [x] Use context in CLI commands (cobra context)
+
+## Phase 4: cmd/ Tests
+- [x] Test add command
+- [x] Test ls command
+- [x] Test promote/demote commands
+- [x] Test delete command
+- [x] Test absorb command
+
+## Phase 5: Backup/Export
+- [x] nib export — dump entities to JSON
+- [x] nib backup — safe SQLite backup (handles WAL)

+# Development Guide
+
+## Prerequisites
+
+- Go 1.24+
+- [air](https://github.com/air-verse/air) (live-reload, install: `go install github.com/air-verse/air@latest`)
+- OpenSSL (for dev TLS certs)
+
+## Quick Start
+
+```sh
+make cert       # one-time: generate self-signed TLS cert
+make watch      # start dev server with live-reload (HTTP, port 4444)
+```
+
+## Make Targets
+
+### Build
+
+| Target | Description |
+|--------|-------------|
+| `make build` | Compile production binary (`./nib`) |
+| `make dev` | Run dev server from source (HTTP, port 4444) |
+| `make watch` | Live-reload dev server via air — auto-rebuilds on save |
+
+### Quality
+
+| Target | Description |
+|--------|-------------|
+| `make test` | Run all tests |
+| `make test-v` | Run all tests with verbose output |
+| `make test-cover` | Run tests with per-function coverage report |
+| `make lint` | Run vet + format check |
+| `make vet` | Static analysis via `go vet` |
+| `make fmt` | Auto-format all Go files |
+| `make fmt-check` | Check formatting without modifying (CI-friendly) |
+
+### Utility
+
+| Target | Description |
+|--------|-------------|
+| `make cert` | Generate self-signed dev TLS cert in `certs/` (valid 365 days) |
+| `make clean` | Remove build artifacts |
+| `make tidy` | Tidy and verify Go module dependencies |
+| `make run ARGS="..."` | Build then run with custom args |
+| `make help` | List all targets |
+
+## TLS
+
+nib supports TLS via `--tls-cert` and `--tls-key` flags on the `serve` command.
+
+### Dev (self-signed)
+
+```sh
+make cert
+make run ARGS="serve --tls-cert certs/dev.crt --tls-key certs/dev.key"
+```
+
+Serves HTTPS on port 4443. Browser will warn about the self-signed cert — accept once.
+
+This is needed for features that require a secure context (e.g. clipboard API).
+
+### Production
+
+For production, use a reverse proxy (Caddy, nginx) with real certificates in front of nib's HTTP server. Alternatively, pass real cert/key paths directly:
+
+```sh
+./nib serve --tls-cert /path/to/cert.pem --tls-key /path/to/key.pem
+```
+
+### Port Defaults
+
+| Mode | Default Port |
+|------|-------------|
+| HTTP | 4444 |
+| HTTPS | 4443 |
+
+Override with `--port` or the `NIB_PORT` environment variable.
+
+## Terminal UI
+
+Run the TUI directly from source:
+
+```sh
+go run . tui
+```
+
+TUI code lives in `internal/tui/`. No live-reload — restart manually after changes.
+
+## Typical Workflow
+
+1. `make cert` — once, generates dev TLS cert
+2. `make watch` — start coding, air rebuilds on save
+3. Edit code, save, changes appear automatically
+4. `make test` — verify nothing broke
+5. `make lint` — check formatting and vet
+6. Commit and push
