feat(method): refuse default stopword deletion of report language

[seonghobae]

A default or global stopword list cannot erase repeated report language (ADR 0004/0012). Recovery is the computed share of recovered deletion kinds that match known truth versus collapsing every token treatment to stopword deletion.

Complementary to #63 TF-IDF/BM25 inferential weights and #75 method_effects (explicit template/section/style sources). This crate owns the default-stopword-deletion prohibition.

Local gates:

• cargo test -p stopword_deletion --all-targets GREEN after RED (refuse_default_stopword_deletion returned Ok for DefaultStopwordList)
• clippy -D warnings PASS
• workspace contract PASS
• docstring contract PASS
• lines 71/71; nightly-2026-08-01 branches 6/6

Does not allocate migration 0008. Does not recreate method_effects, topic_measurement, 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. Do not empty-commit.

Current head 7974d75eec78ab877bd4351f8a82f5ed8f8a4268 includes the normal merge of origin/main and conflict resolution for CHANGELOG.md/DOCUMENTATION.md. Focused verification passed: cargo fmt --check, cargo test -p stopword_deletion --offline (6 tests), workspace contracts, docstring quality, and git diff --check. The exact-head GitHub Checks are running; merge still requires one qualifying independent approval under the live branch rules.

✅ Devin Review: No Issues Found

Devin Review analyzed this PR and found no bugs or issues to report.

[seonghobae]

Please perform an exact-head OpenCode review of 7974d75 against base main at 7c29e7c. Review only this SHA; do not merge or update the branch.

@opencode-agent @cwl-noema-review

Review-only request for exact current head `7974d75eec78ab877bd4351f8a82f5ed8f8a4268`. Re-review language-aware method semantics, multilingual measurement invariance, 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 #145 at head 7974d75eec78ab877bd4351f8a82f5ed8f8a4268. 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 7974d75:

• Default stopword deletion is not treated as a neutral transformation of report language; the method contract preserves the distinction between lexical preprocessing and inferential meaning.
• git diff --check, documentation validation, workspace contract, docstring contract, and cargo fmt --all -- --check passed locally.
• All 16 current hosted checks pass, including Rust tests, PostgreSQL integration, coverage, security scans, and Strix.
• No new actionable source defect was found at this exact head; no approval is being self-issued.

[seonghobae]

Current-head review refresh for 696d56c:

• Root cause fixed: the stopword-deletion ADRs carried trailing whitespace in changed lines, and the branch was also stale against main. I removed the whitespace and merged the current main, resolving the CHANGELOG conflict while preserving both the stopword and naruon release entries.
• Local documentation, workspace, docstring, formatting, diff, and merge-tree checks pass.
• GitHub now reports MERGEABLE; the exact-head required checks are pending and no qualifying independent approvals are present yet.
• No protected-branch bypass or self-approval was used.

[seonghobae]

Current-head review request: exact head 696d56c5816815e22181a03c57a822f974d41706 has no actionable 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.

Exact-head queue disposition

Exact head 696d56c5816815e22181a03c57a822f974d41706 is green across required Checks with no failed or queued gate. The bounded stopword-deletion identity crate and documentation remain mechanically mergeable, but REVIEW_REQUIRED has no qualifying independent approval. WAIT_AND_REMEDIATE; no bypass.
