Fixes a factory bottleneck: valid GitHub heading anchors produce false unresolved documentation references.

Problem

Phase C — molty retirement previously reduced to phase-c-molty-retirement; GitHub uses phase-c--molty-retirement. Graph extraction and intent check also had duplicate, inconsistent reducers.

Goal

Use one GitHub-compatible character-reduction function for graph extraction and Markdown link checking.

Decisions

Keep existing ASCII fast paths. A lazy Unicode-category regex retains Alphabetic characters, decimal/letter numbers, marks and connector punctuation. Other_Number characters such as ², ½ and ① are removed; alphabetic Other_Symbol characters such as ⓐ survive. Every ASCII space becomes a hyphen; hyphens are not collapsed or trimmed. Remove the duplicate reducer from lib.rs.

Character policy and representative Other_Number/Other_Symbol fixtures follow https://github.com/Flet/github-slugger/blob/3461c435/script/generate-regex.js and its test/fixtures.json.

Verification

At 161d9bc:

gate-slot --class heavy -- nix develop --command env -u DIRSTACK RUSTC_WRAPPER= CARGO_BUILD_RUSTC_WRAPPER= cargo test --manifest-path crates/intent/Cargo.toml
12 unit tests passed; 11 gateway integration tests passed; 16 CLI integration tests passed.
Doc tests: 0 tests. Exit 0.

Includes Unicode-category regressions, spacing and collision fixtures, and strict intent check accepting both local and cross-file #phase-c--molty-retirement destinations. One new review-fix commit, no amend.

Complexity

Adds regex as a direct dependency (already transitive). Sharing the reducer removes duplicate implementation rather than adding an abstraction.

Concerns

This remains raw-heading reduction, not full Markdown inline parsing. Link destinations and underscore emphasis are not parsed, so these cases can still diverge from rendered GitHub headings. Unicode properties follow the regex crate's Unicode version rather than pinning github-slugger's Unicode 13 tables.

Friction & bottlenecks

Earlier Cargo attempts encountered an agent-command-shell guard refusal. The compiler-wrapper-disabled test command above succeeds without bypassing the guard. A requested destructive reset was refused; used the prescribed keyed-stash alternative to preserve identical edits before fast-forwarding the test checkout.

Follow-ups

Rendered inline-Markdown parsing is outside this character-reduction fix.

Review record at exact head 161d9bc:

• Independent review (ReviewIntent20, reviewer subagent): NO-GO at f608aa7 (Other_Number was kept, the Alphabetic exception was missing, and lib.rs had a duplicate collapsing reducer). The delta re-review at 161d9bc gives GO with no findings.
• cargo test on dev5: 12 unit + 11 gateway + 16 CLI integration tests pass.
• Consumer proof: dotfiles #6604 repins to this head. The axe build passes, and check:docs:vrs-links goes from 18 to 5 known-broken with 0 new findings.
