# Deno-exclusive roadmap

## Phases

### D-0 — Inventory freeze

|            |                                                                            |
| ---------- | -------------------------------------------------------------------------- |
| **Work**   | Publish inventory + matrix; pin Deno version; classify exclusive vs shared |
| **Exit**   | High-traffic Deno-only surfaces listed                                     |
| **Status** | **Docs in progress (this tree)**                                           |

### D-1 — Permissions

|                |                                                                          |
| -------------- | ------------------------------------------------------------------------ |
| **Work**       | Capability host; CLI flags; `Deno.permissions.*`; fail closed by default |
| **Exit**       | Deny-by-default tests; grant paths for read/net/env                      |
| **Depends on** | Embed `Caps` design (scripty already sketches capabilities)              |

### D-2 — Core I/O namespace

|                |                                                                       |
| -------------- | --------------------------------------------------------------------- |
| **Work**       | `Deno.env`, args, cwd, read/write text/file, mkdir/stat/remove subset |
| **Exit**       | File + env smokes under permission checks                             |
| **Depends on** | D-1                                                                   |

### D-3 — Net / serve

|                |                                                      |
| -------------- | ---------------------------------------------------- |
| **Work**       | `Deno.listen` / `Deno.serve` shapes; basic TLS later |
| **Exit**       | HTTP hello smoke                                     |
| **Depends on** | D-1, host net                                        |

### D-4 — Deno KV

|                |                                            |
| -------------- | ------------------------------------------ |
| **Work**       | Local KV backend; `openKv`; get/set/atomic |
| **Exit**       | KV smoke; queues optional later            |
| **Depends on** | D-2                                        |

### D-5 — FFI, test, long tail

|                |                                                                                                                                                                                                                                   |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Work**       | `Deno.dlopen`; `Deno.test` / `Deno.bench`; telemetry/lint/cron; remaining FS/net; `Deno.jupyter` optional/refuse                                                                                                                  |
| **Exit**       | Every [inventory](/scripty/v0.0.1-dev/deno-exclusive/inventory) row classified terminal (`supported` or explicit refuse) and mapped in the [matrix](/scripty/v0.0.1-dev/deno-exclusive/matrix) (matrix **Coverage** check passes) |
| **Depends on** | D-2…D-4                                                                                                                                                                                                                           |

### D-6 — Dogfood

|                |                                                        |
| -------------- | ------------------------------------------------------ |
| **Work**       | Sample: permissioned static server; KV counter service |
| **Exit**       | Key rows `dogfooded`                                   |
| **Depends on** | D-3, D-4                                               |

## Suggested priority order

```text theme={null}
Permissions (deny by default)
  → Deno.readTextFile / writeTextFile / env / args
  → Deno.serve
  → Deno.Command
  → Deno.openKv
  → Deno.dlopen
  → Deno.test / long tail
```

## Risks

| Risk                                  | Mitigation                                |
| ------------------------------------- | ----------------------------------------- |
| Rebuilding all of Node under `Deno.*` | Exclusive filter + “shape wrapper” labels |
| Permission UX vs embed hosts          | Shared capability model with yappy/DX     |
| KV scope creep (hosted)               | Local-first; remote optional refuse       |
| Overlap confusion with `Bun.serve`    | Separate matrices; both allowed           |

## Relationship to I1 / I2

* Language features for modern Deno code → **I1**
* Bun-only APIs → **I2** (parallel, different namespace)
* Shared Web APIs (`fetch`) → not I3
