DEPENDENCY_POLICY.md

@@ -1,65 +0,0 @@
-# Dependency Policy
-
-This document describes how the Rust MCP SDK (`rmcp`, `rmcp-macros`) selects,
-updates, and maintains its dependencies. It applies to all crates in the workspace.
-
-## Goals
-
-- Keep dependencies current and secure without churn that destabilizes the public API.
-- Minimize the dependency footprint we impose on downstream users.
-- Make dependency updates reviewable and traceable.
-
-## Choosing dependencies
-
-Before adding a new dependency we consider:
-
-- **Necessity** — whether the functionality is worth an added dependency, or is small
-  enough to implement directly.
-- **Maintenance & trust** — active maintenance, a healthy release history, and a
-  permissive, compatible license (the workspace is `Apache-2.0`).
-- **Footprint** — transitive dependency count and compile-time cost.
-- **Optionality** — anything not needed by every user should sit behind a Cargo
-  feature so downstream builds stay lean. The SDK is heavily feature-gated for this
-  reason (transports, `auth`, `schemars`, `reqwest`, etc.).
-
-Version requirements are specified with caret (`^`, the Cargo default) constraints so
-compatible upgrades are picked up automatically.
-
-## Automated updates
-
-Dependency updates are automated with [Dependabot](https://docs.github.com/en/code-security/dependabot),
-configured in [`.github/dependabot.yml`](.github/dependabot.yml):
-
-| Ecosystem      | Cadence | PR label          |
-| -------------- | ------- | ----------------- |
-| Cargo crates   | Weekly  | `T-dependencies`  |
-| GitHub Actions | Daily   | `T-CI`            |
-
-Dependabot opens a limited number of PRs at a time (currently 3 per ecosystem) to
-keep the review queue manageable. Update PRs run the full CI suite (build, format,
-clippy, tests, and conformance) and must be green before merge.
-
-## Review and merge
-
-- Patch and minor updates that pass CI are reviewed and merged promptly by maintainers.
-- Major (breaking) updates are evaluated individually; they may require code changes
-  and are scheduled deliberately rather than merged automatically.
-- Any dependency change that affects the **public API** (for example a type re-exported
-  from a dependency) is treated as a potential breaking change and follows
-  [`VERSIONING.md`](VERSIONING.md).
-
-## Security updates
-
-- Security fixes take priority over routine updates and are expedited.
-- Vulnerabilities in the SDK itself are handled per [`SECURITY.md`](SECURITY.md) via
-  GitHub's private Security Advisory process.
-- Advisories affecting our dependencies (e.g. via the [RustSec Advisory Database](https://rustsec.org/))
-  are addressed as soon as a fixed version is available; if a released version of the
-  SDK is impacted, a patched release is published and, where warranted, the affected
-  versions are yanked from crates.io.
-
-## Minimum Supported Rust Version
-
-Dependency upgrades must not raise the SDK's declared MSRV (`rust-version` in
-`Cargo.toml`) without an explicit, documented MSRV bump — which is itself treated as a
-breaking change per [`VERSIONING.md`](VERSIONING.md).

-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:

-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-issue triage and critical-bug (P0) resolution are within the Tier 1 SLAs, the
-governance documents (`VERSIONING.md`, `DEPENDENCY_POLICY.md`, this `ROADMAP.md`) are
-published, and all 48 non-experimental features are documented with examples. This
-document now serves as the ongoing tracker for spec conformance and SDK health.

-Only date-versioned scenarios count toward SDK tiering. `draft` (2026-07-28 draft)
-and `extension` scenarios are informational and reported separately below.
-
-> **Tooling note — `stable_release`:** the SEP-1730 `tier-check` CLI may report
-> `stable_release` as failing because it does not parse the workspace tag prefix
-> `rmcp-v` (as in `rmcp-vX.Y.Z`). The published releases are genuine stable,
-> non-pre-release versions ≥1.0.0
-> ([Releases](https://github.com/modelcontextprotocol/rust-sdk/releases)); the
-> flag is a tooling artifact, not an unmet requirement.

-## Conformance
-
-Per-scenario status for the current spec is tracked in the epic issue
-[#977 — Tracking: 2026-07-28 spec conformance](https://github.com/modelcontextprotocol/rust-sdk/issues/977),
-under the [`2026-07-28 spec` milestone](https://github.com/modelcontextprotocol/rust-sdk/milestone/3).
-
-CI (`.github/workflows/conformance.yml`) runs the full `2025-11-25` and `2026-07-28`
-server and client suites on every push and PR. Both suites are fully green.
-
-### Informational (not scored for tiering)
-
-Extension-tagged scenarios are excluded by `--spec-version` filters, so CI runs them
-in separate steps against `conformance/expected-failures-extensions.yaml`:
-
-| Scenario                                | Tag        | Status |
-| --------------------------------------- | ---------- | ------ |
-| `auth/client-credentials-basic`         | extension  | ✅ Pass |
-| `auth/client-credentials-jwt`           | extension  | ✅ Pass |
-| `auth/enterprise-managed-authorization` | extension  | ❌ Expected failure (not implemented by the conformance client) |
-| `auth/wif-jwt-bearer`                   | 2026-07-28 draft | ❌ Expected failure (WIF / SEP-1933, draft) |
-| `tasks-*` (SEP-2663)                    | extension  | ❌ 9 expected failures · ⏭️ 1 upstream-skipped |

-### Spec features without conformance scenarios
-
-Conformance does not cover the entire spec surface. Remaining feature work tracked via
-the milestone:
-
-- SEP-2567 sessionless MCP via explicit state handles (#870)
-- SEP-2260 server requests must associate with a client request (#873)
-- SEP-2549 follow-up: client-side TTL-honoring cache (#974)

-## Completed
-
-### Tier 1 requirements
-
-- [x] **v3.0.0 stable released** (2026-07-28) — MRTR, SEP-2549 cache hints, SEP-2243
-      standard headers, SEP-2575 stateless MCP, and SEP-2106 relaxations
-- [x] 2025-11-25 server conformance 100% (30/30)
-- [x] 2025-11-25 client conformance 100%
-- [x] 2026-07-28 server conformance 100% (30/30 dated)
-- [x] 2026-07-28 client conformance 100% (dated)
-- [x] Issue triage ≥90% within 2 business days (95.2%, 20/21) with the full SEP-1730
-      label taxonomy (bug, enhancement, question, needs confirmation, needs repro,
-      ready for work, good first issue, help wanted, P0–P3)
-- [x] All P0 bugs resolved within 7 days (0 open; #741 resolved in 3 days). #815 was
-      reclassified from `P0` to `T-security` — it was a CVE/advisory-coordination task
-      for an already-shipped fix (PR #764, released in v1.4.0), not a critical-bug fix
-- [x] `VERSIONING.md` — semver scheme, breaking-change definition, and communication policy
-- [x] `DEPENDENCY_POLICY.md` — published dependency update policy (with `.github/dependabot.yml`)
-- [x] `SECURITY.md` and Dependabot configuration
-- [x] All 48 non-experimental features documented with examples in the README
-      (closed the last 6 gaps on 2026-07-30: audio results, resource-template reading,
-      resource-argument completion, ping, and the legacy HTTP+SSE non-goal writeup)
-
-### Spec implementation
-
-- [x] SEP-2322 MRTR (server scenarios + `sep-2322-client-request-state`)
-- [x] SEP-2575 Make MCP Stateless (`server-stateless`)
-- [x] SEP-2164 resource not found
-- [x] SEP-2549 cache hints (`caching`)
-- [x] SEP-2243 HTTP standardization (`http-header-validation`, standard headers)
-- [x] DNS rebinding protection

-## Nice-to-have (scorecard hygiene, not required for Tier 1)
-
-- [ ] Add a top-level `CHANGELOG.md` (release notes are currently managed by release-plz).
-- [ ] Add a top-level `CONTRIBUTING.md` (contributor docs currently live at `docs/CONTRIBUTE.MD`).
