feat(hooks): integrate rtk upstream as external CLI for token reduction#2

Conversation
Add PreToolUse hook delegating eligible Bash commands to the upstream rtk binary (rtk-ai/rtk, v0.34.3) for 60-90% token reduction. RTK is treated as an optional external dependency (install via brew or cargo --git), invoked verbatim from the hook, never absorbed into the codebase. Hook degrades silently when rtk is missing. Documented: - ADR-032: install-not-absorb policy for standalone CLI tools, contrasted with ADR-027's absorb-not-install for Claude Code plugins - CLAUDE.md: install instructions with explicit warning against cargo install rtk (crate-name collision on crates.io with an unrelated Lua toolkit) - docs/diagrams: comparative architecture (9Router proxy MITM vs RuFlo in-process hook) plus the final RuFlo+RTK integration diagram - docs/plans/260511-gpoapa: retrospective PRD documenting the change Negative reference: 9router/open-sse/rtk/ reimplemented rtk in JS inside a MITM proxy (~1000 LOC owned, no upstream tests, degraded 20-40% claim). RuFlo invokes the upstream binary instead. Refs: 260511-gpoapa Co-Authored-By: claude-flow <ruv@ruv.net>
The RTK PreToolUse hook was originally added to .claude/hooks/ only, which is the local repo mirror — not the canonical source-of-truth. Per the repo pattern (scripts/init-arquetipo.sh:208, tests/*.sh, and scripts/gen-reference.sh:80), docs/arquetipo/deliverables/hooks/hooks/ is the canonical location that ships in the npm package and is copied to user projects on init. Changes: - Add canonical rtk-rewrite.sh under deliverables/hooks/hooks/ (identical to the .claude/hooks/ mirror that was added in the previous commit). - Register the rtk hook in the deliverable settings.json under PreToolUse matcher Bash, alongside validate-bash.py and the existing pre-command hook. Bump _meta.hooks_count from 15 to 16. - Add a check_mirror_sync function to tests/hooks-syntax-suite.sh that diffs .claude/hooks/<file> vs deliverables/hooks/hooks/<file> for an allow-list of tracked files (starting with rtk-rewrite.sh). Fails the suite if they drift. Legacy drift on other files is not yet in scope; the list will be extended as those are reconciled separately. Test suite: PASS=29 FAIL=0 (was 28, +1 mirror check).

Documentation and version bump for the alpha.12 release. Code changes landed in the previous two commits of PR #2 (260511-gpoapa). - README.md: new "RTK Token Reduction (optional)" section with the three valid install commands, the name-collision warning, and a pointer to ADR-032. Features table updated (24 -> 25 hooks; added RTK row). - package.json: 1.0.0-alpha.11 -> 1.0.0-alpha.12. publishConfig and files arrays unchanged; rtk-rewrite.sh ships inside the existing docs/arquetipo/deliverables/** glob. - RELEASE-NOTES.md: rewritten for alpha.12. Highlights focus on the RTK integration, ADR-032, the anti-drift test, the diagrams, and the workflow audit (process miss + retroactive PRD). Migration path is purely additive (no breaking changes from alpha.11). The release.yml workflow fires on push of tag v1.0.0-alpha.12. This commit does not create or push that tag - tag creation is deferred until PR #2 is merged to main. Refs: 260511-gpoapa, PR #2, ADR-032 Co-Authored-By: claude-flow <ruv@ruv.net>

Wave C C3 of ADR-036. Hookifies the §9 File rule doctrine: post-edit hook conditionally invokes smell-scanner which detects canonical smells (bare catch, TODO without link, function >30 LoC, cyclomatic >10) on the diff and auto-files issues with dedupe via AgentDB pattern-store cache. 9 AC across 7 slices. Default-off via SMELL_SCAN_ENABLE=1 (ADR-035 pattern). Supersedes the original Brecha #2 collateral-issuer.mjs proposal. Refs #11 #12 #13 #14 #15 #16 #17. Co-Authored-By: claude-flow <ruv@ruv.net>

Wires the upstream
rtkbinary (github.com/rtk-ai/rtk, v0.34.3) into RuFlo via a PreToolUse hook for 60-90% token reduction on Bash tool outputs. RTK is treated as an optional external CLI dependency (install viabreworcargo install --git), invoked from the hook verbatim, never absorbed into this repo.PRD

ADR-032 — Status: Proposed. Clarifies that ADR-027's "absorb-not-install" policy applies to Claude Code plugins, while RTK (a standalone CLI binary) follows the inverse "install-not-absorb" pattern, same as
