 ### 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

+# CAM Usage Workflow
+
+Step-by-step order for moving Cursor agent context between workstations.
+
+**Repository:** <https://git.p7net.ru/tools/cam.git>  
+**Version:** 0.1.0 (in development)
+
+---
+
+## 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
+
+```bash
+git clone https://git.p7net.ru/tools/cam.git tools/cam
+pip install -r tools/cam/requirements.txt
+```
+
+### 2. Workstation config
+
+```bash
+cp tools/cam/config/workstations/macos.example.yml tools/cam/config/workstations/local.yml
+```
+
+Required fields:
+
+```yaml
+workstation:
+  id: "nt-041"
+  index: "w1"          # w1, w2, … — prefix for auto codes
+
+context:
+  prefix_workstation: true    # w1-1 (true) or 1 (false)
+  auto_format: "{ws}-{seq}"
+  subagent_format: "{parent}.{seq}"
+
+registry:
+  file: "registry.yaml"
+```
+
+### 3. Verify
+
+```bash
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml paths
+```
+
+---
+
+## Before leaving a workstation
+
+```bash
+# 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-*'
+```
+
+Commit project archive:
+
+```bash
+git add docs/cursor_agents/
+git commit -m "Export Cursor agent contexts (w1)"
+git push
+```
+
+---
+
+## 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-*'
+```
+
+Close Cursor before import. For new agent work, prefer `@markdown/w1-11--….md`.
+
+---
+
+## Manual context codes
+
+```bash
+# list all codes
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml code list
+
+# rename w1-11 → thematic code
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml code set w1-11 w1.git.zakaz
+
+# show details
+python tools/cam/cam.py -c tools/cam/config/workstations/local.yml code show w1.git.zakaz
+```
+
+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
+
+| 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 |
+
+Flags: `--context CODE`, `--mask PATTERN` (glob: `w1-*`, `*.git.*`).
+
