feat(relation): refuse a summary as the source identity

[seonghobae]

A summary may point at earlier event time (ADR 0003). It cannot become a state transition or reuse the source document identity. Recovery is the computed share of recovered kinds that match known truth versus collapsing every summary to the source.

Complementary to #120 citation, #130 support, #136 translation, #137 retrospective, and #138 outcome_order. This crate owns the remaining closed provenance kind `summarizes`.

Local gates:

• `cargo test -p summarizes_edge --all-targets` GREEN after RED (package did not exist)
• clippy `-D warnings` PASS
• workspace contract PASS
• docstring contract PASS
• lines 14/14; nightly-2026-08-01 branches 6/6

Does not allocate migration `0008`. Does not recreate `outcome_order` or other in-flight crates.

Keep this PR draft. Preferred merge remains #46 only when exact-head required Checks pass and a qualifying independent (non-Cursor/CodeRabbit) APPROVE exists. OpenCode `CHANGES_REQUESTED` on #46 is a coverage-evidence race — do not empty-commit.

Current head bb277d9 now includes origin/main; the only merge conflict was the changelog. Exact-head proof passed: cargo fmt --all -- --check; cargo test -p summarizes_edge --offline (6 tests); workspace contract; documentation validation; Rust docstring contract; git diff --check. Protected merge still requires current Checks and an independent approval.

[seonghobae]

Current-head validation update (7108baa): fixed the quality contract to derive the Rust crate count from scripts/check_workspace_contract.py instead of hard-coding 10. Local evidence: 89 quality tests passed; coverage 100% (991/991 statements, 442/442 branches); workspace, docstring, documentation, and diff checks passed. Please review and rerun Checks against this exact head; merge remains subject to the repository's two independent approvals and protected rules.

@opencode-agent @cwl-noema-review

Review-only request for exact current head 7108baa11d724265c2cd6422371642f3424ad205. Re-review source-identity refusal for summaries, temporal/relational semantics, realistic tests, docs/APA traceability, and protected-merge requirements. Do not merge or enable auto-merge.

[seonghobae]

Queued @cwl-noema-review and @opencode-agent for PR #139 at head 7108baa11d724265c2cd6422371642f3424ad205. Central exact-name Actions artifacts are the durable dispatch ledger; existing review workflows remain authoritative for the final verdict and failure evidence.

[seonghobae]

Current-head review refresh for 7108baa:

• A summary artifact cannot replace the source identity required for relation and measurement provenance.
• git diff --check, documentation validation, workspace contract, docstring contract, and cargo fmt --all -- --check passed locally.
• The displayed failed checks were cancelled runs, not failed steps. The Rust Foundation CI run was explicitly requeued for this exact head and is currently queued; merge remains withheld until revalidation and qualifying approvals complete.
• No source defect was found at this exact head; no approval is being self-issued.

[seonghobae]

Rebased current head 43ebbda onto origin/main. The changelog conflict retains both the summary-edge and current-main entries; inherited documentation trailing whitespace was removed. Local merge-tree, git diff --cached --check, and cargo fmt --all -- --check pass. Exact-head hosted checks and required independent approvals remain required before protected merge.

[seonghobae]

Current-head review request: exact head 43ebbda0d35f9bf227c5764d53d429fff0f08c8c has no actionable inline findings in the available review data; all terminal checks are green and coverage-evidence remains queued. Please review this exact head. No merge bypass is requested.
