Rename Open Context Protocol (OCP) → Context Graph Protocol - #1
Merged
Conversation
Rebrand the entire project from "Open Context Protocol" / "OCP" / "ocp" / "opencontextprotocol" to "Context Graph Protocol". Tagline: "The canonical architecture for building context graphs that agents use to reason over." - Crates: ocp-types/ocp-host/ocp-conformance -> contextgraph-types/-host/ -conformance (dirs, [package].name, path deps, Rust `use` paths, keywords). - Binaries: ocp-inspect -> contextgraph-inspect, ocp-example-docs -> contextgraph-example-docs (incl. CARGO_BIN_EXE_ references). - Wire protocol version: ocp/1.0-draft -> contextgraph/1.0-draft (PROTOCOL_VERSION and every ocp/ literal in tests, in lockstep; mcp/ left untouched). - Schema: schema/ocp-envelope.schema.json -> schema/contextgraph-envelope.schema.json; $id host opencontextprotocol.org -> context-graph-protocol.org. - Assets: ocp-logo.svg -> contextgraph-logo.svg (repo + site/public). - Repo/URL form opencontextprotocol -> context-graph-protocol (GitHub org path, docs.rs/crates.io links). Crate READMEs now link this repo's own docs, not the stella docs/ocp mirror. - Prose: "Open Context Protocol"/"OCP" -> "Context Graph Protocol" spelled out, no new acronym (consistent with the contextgraph identifier stem). Verified: cargo build + cargo test (46 tests) green; schema/validate-examples.py all pass; docs-site witness test OK; site tsc --noEmit clean.

…og, and backfill the gaps (#73) CHANGELOG.md relied on every PR remembering to write its own [Unreleased] entry. An audit of the 22 merges since v0.1.0 whose numbers never appear in the file found 9 user-visible changes with no entry at all — including the OCP -> CGP rename itself, the repo's biggest breaking change. The Unreleased section had also accumulated duplicate category headings (two '### Added', two '### Changed', two '### Fixed') from PRs appending their own blocks. Go-forward: .github/workflows/changelog.yml watches pushes to main. When a merge lands without touching CHANGELOG.md, it drafts the missing entries from the merge's actual diff (.github/scripts/changelog-ai.sh, Vercel AI Gateway, degrade-open: no key or a failed call is a log line, never a red check) and proposes them as a bot/changelog PR — a draft for human review, never a direct push. The gap is measured from the last commit that touched CHANGELOG.md, so merging the bot PR resets it, and each run regenerates the whole current gap, so a superseded bot PR loses nothing. Backfill: entries for the rename (#1), frame identity/composition/usage reports (#32), golden wire fixtures (#35), ADR 0007 (#61, #27), composition conformance + the canary scheduled-run gate (#70) — written from each PR's diff, in the file's existing voice. Three further audit hits (#68, #69, #71) turned out to be already covered by newer entries and were left alone. Duplicate category headings merged: one heading per category, Keep-a-Changelog order.

oxagen-platformhas its own independent copy ofocp-types/-host/-conformance(self-contained path deps; not broken by this rename). Renaming those is a separate decision.ocp-*@0.1.0crates are untouched here; publishingcontextgraph-*(and optionally yankingocp-*) is a post-merge step.context-graph-protocol.orgdomain used in the schema$id.
