 All notable changes to **CAM (Cursor Agents Manager)** are documented in this file.
 
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
-
-## [Unreleased]
-
-### Added
-
-- `USAGE.md` — step-by-step workflow (setup, export, import, daily sync between workstations)
-
-## [0.0.1] - 2026-07-10
+## [0.1.0] - 2026-07-13
 
 ### Status
 
-Initial release. **In development.**
+**In development.** Context registry and readable file names.
 
 ### Added
 
-- CLI `cam.py` with subcommands: `export`, `import`, `list`, `paths`
-- Export Cursor `agent-transcripts` to a project archive:
-  - `raw/` — original `.jsonl` files
-  - `markdown/` — readable session exports
-  - `manifest.json` — machine-readable registry
-  - `INDEX.md` — session index with links
-- Import archived `raw/` transcripts back into Cursor `agent-transcripts` folder
-- YAML workstation configuration (`config/config.example.yml`, OS-specific examples)
-- Auto-detection of Cursor transcripts path from project root
-- `export.index_language`: `en` or `ru` for generated Markdown
-- `import.overwrite_existing` safety flag (default: `false`)
-- `--dry-run` for import
+- **Context codes** (`w1-1`, `w2-110`, manual `w1.git.001`, …) stored in `registry.yaml`
+- **Readable markdown files** for Cursor `@` picker: `{code}--{topic-slug}.md`
+- **Stable paths** — re-export updates the same file for a given context code
+- **Workstation index** (`workstation.index: w1`) in config; optional `prefix_workstation: false`
+- **Selective export/import** via `--context CODE` and `--mask PATTERN` (e.g. `w1-*`, `w1.git.*`)
+- **`cam code`** subcommands: `list`, `set`, `show` for manual code assignment
+- Auto-migration from legacy UUID-based `manifest.json` on first export
+- Legacy UUID markdown cleanup (`context.cleanup_legacy_files`)
+- Subagent codes: `{parent}.{seq}` (e.g. `w1-11.1`)
 
+### Changed
+
+- `INDEX.md` shows context code column and workstation of origin
+- `manifest.json` includes `context_code`, `created_workstation`, `manual_code`
+- Markdown front matter includes `context_code` and `created_workstation`
+
+## [0.0.1] - 2026-07-10

 Step-by-step order for moving Cursor agent context between workstations.

+## Context codes (readable names)
+
+Each agent session gets a **context code** stored in `registry.yaml`:
+
+| Code type | Example | Meaning |
+|-----------|---------|---------|
+| Auto main | `w1-1`, `w2-110` | `{workstation.index}-{seq}` |
+| Auto subagent | `w1-11.1` | `{parent}.{seq}` |
+| Manual | `w1.git.001`, `sync-crm3` | Assigned by operator |
+
+Markdown files use readable names for Cursor `@`:
+
+```
+docs/cursor_agents/markdown/w1-11--Из-исходной-базы-в-целевую.md
+docs/cursor_agents/markdown/w1.git.001--sync-analysis.md
+```
+
+**Re-export updates the same file** for a given code (consolidated/enriched context overwrites in place).
+
+In a new Cursor chat:
+
+```
+@docs/cursor_agents/markdown/w1-11--Из-исходной-базы-в-целевую.md
+```
+
+or reference by code:
+
+```
+Context w1-11 — continue transfer of customer orders.

 ## One-time setup (each workstation)
 
-### 1. Clone CAM into the project
-
-From the **consumer project root** (e.g. `crm3-migration`):
+### 1. Clone CAM
 
 ```bash
 git clone https://git.p7net.ru/tools/cam.git tools/cam
-cd tools/cam
-pip install -r requirements.txt
+pip install -r tools/cam/requirements.txt
 ```
 
-### 2. Create a local workstation config
+### 2. Workstation config
 
 ```bash
-cp config/workstations/macos.example.yml config/workstations/local.yml
-# Windows: cp config/workstations/windows.example.yml config/workstations/local.yml
+cp tools/cam/config/workstations/macos.example.yml tools/cam/config/workstations/local.yml
 ```
 
-Edit `config/workstations/local.yml`:
+Required fields:
 
-| Key | Set to |
-|-----|--------|
-| `workstation.id` | Short ID for this PC (e.g. `nt-041`, `office-pc`) |
-| `project.root` | **Absolute** path to the project opened in Cursor |
-| `export.output_dir` | Usually `docs/cursor_agents` |
-| `export.index_language` | `en` or `ru` |
+```yaml
+workstation:
+  id: "nt-041"
+  index: "w1"          # w1, w2, … — prefix for auto codes
 
-`local.yml` is **gitignored** — never commit real paths to the public CAM repo.
+context:
+  prefix_workstation: true    # w1-1 (true) or 1 (false)
+  auto_format: "{ws}-{seq}"
+  subagent_format: "{parent}.{seq}"
 
-### 3. Verify paths
+registry:
+  file: "registry.yaml"
+```
+
+### 3. Verify
 
 ```bash
-python cam.py -c config/workstations/local.yml paths
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml paths
 ```
 
-Check `transcripts_dir` points to your Cursor `agent-transcripts` folder.
-
 ---
 
-## Before leaving a workstation (save context)
-
-Run from the **project root**:
+## Before leaving a workstation
 
 ```bash
-source .venv-nt-041/bin/activate   # or your project venv
+# all contexts
 python tools/cam/cam.py -c tools/cam/config/workstations/local.yml export
+
+# one context
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml export --context w1-11
+
+# by mask
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml export --mask 'w1-*'
 ```
 
-This updates in the project:
-
-- `docs/cursor_agents/raw/` — JSONL transcripts
-- `docs/cursor_agents/markdown/` — readable exports
-- `docs/cursor_agents/manifest.json`, `INDEX.md`
-
-Commit and push the **consumer project** repository:
+Commit project archive:
 
 ```bash
 git add docs/cursor_agents/
-git commit -m "Export Cursor agent history from <workstation-id>"
+git commit -m "Export Cursor agent contexts (w1)"
 git push
 ```
 
 ---
 
-## On a new workstation (restore context)
-
-### 1. Clone the consumer project
-
-```bash
-git clone https://git.p7net.ru/rhana/crm3-migration.git crm3-26
-cd crm3-26
-```
-
-See the project’s `docs/meta/REPOSITORIES.md` for other required clones (configs, `tools/run_bsl`, etc.).
-
-### 2. Set up CAM (one-time on this PC)
-
-```bash
-git clone https://git.p7net.ru/tools/cam.git tools/cam
-cp tools/cam/config/workstations/macos.example.yml tools/cam/config/workstations/local.yml
-# edit project.root to this machine’s absolute path
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml paths
-```
-
-### 3. Import into Cursor (optional — chat sidebar)
-
-**Close Cursor completely**, then:
+## On a new workstation
 
 ```bash
+git pull
 python tools/cam/cam.py -c tools/cam/config/workstations/local.yml import --dry-run
 python tools/cam/cam.py -c tools/cam/config/workstations/local.yml import
+# or selective:
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml import --mask 'w1-*'
 ```
 
-Re-open Cursor. Existing local files are **not** overwritten unless `import.overwrite_existing: true` in config.
-
-### 4. Continue work with the agent (recommended)
-
-In a new Cursor Agent chat:
-
-```
-@docs/cursor_agents/INDEX.md
-Continue work on <topic>. Context was exported from workstation <id>.
-```
-
-This works reliably across machines; UI import is best-effort.
+Close Cursor before import. For new agent work, prefer `@markdown/w1-11--….md`.

-| Step | Command | Direction |
-|------|---------|-----------|
-| **export** | `python tools/cam/cam.py -c …/local.yml export` | Cursor local → project archive |
-| **import** | `python tools/cam/cam.py -c …/local.yml import` | project archive → Cursor local |
+Rules for manual codes: letters, digits, `.`, `-`, `_` (e.g. `w1.git.001`, `sync-crm3`).
+
+To drop workstation prefix in **new** auto codes only:
+
+```yaml
+context:
+  prefix_workstation: false
+  auto_format: "{seq}"
+```
+
+Existing codes in `registry.yaml` are not renamed automatically.

 ## Command reference
 
-All commands use `-c` **before** the subcommand:
+| Command | Description |
+|---------|-------------|
+| `export` | Cursor → project archive |
+| `import` | project archive → Cursor |
+| `list` | List contexts in archive |
+| `code list` | List codes from registry |
+| `code set TARGET NEW` | Assign/rename code |
+| `code show CODE` | Show context record |
+| `paths` | Resolved paths |
 
-```bash
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml paths
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml export
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml list
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml import --dry-run
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml import
-```
+Flags: `--context CODE`, `--mask PATTERN` (glob: `w1-*`, `*.git.*`).
 
 ---
 
-## CRM3-26 / crm3-migration example
+## Archive layout (0.1.0)
 
-```bash
-# nt-041 (macOS) — template
-cp tools/cam/config/workstations/nt-041.example.yml tools/cam/config/workstations/local.yml
-# set project.root: /Users/you/projects/crm3-26
-
-python tools/cam/cam.py -c tools/cam/config/workstations/local.yml export
-git add docs/cursor_agents/ && git commit -m "Export Cursor agent history" && git push
 ```
-

-
-## Troubleshooting
-
-| Problem | Check |
-|---------|--------|
-| `Transcripts folder not found` | Open project in Cursor once; run `paths`; fix `project.root` |
-| Wrong slug / empty transcripts | `project.root` must match the path Cursor uses exactly |
-| Import skips files | Set `import.overwrite_existing: true` or delete old local transcripts |
-| Chats not in sidebar after import | Use `@docs/cursor_agents/INDEX.md` — UI restore is not guaranteed |
