# T-1814: fw verify-acs NUDGE — suppress for genuinely-subjective [REVIEW] ACs (tone/visual keywords)

## Context

T-1811 added a NUDGE in `lib/verify-acs.sh` that fires whenever a `[REVIEW]` AC's reviewer verdict is `PASS + needs_human=no` — suggesting re-classification to `[REVIEWER]`. Discovered today running `bin/fw verify-acs T-1806`: the NUDGE fires for "Confirm the preamble text strikes the right tone — clear, directive, not preachy" — a genuinely-subjective tone judgment where the reviewer can't replace human judgment. Reviewer's PASS+no-human means "no anti-patterns detected in the AC text"; it does NOT mean "the reviewer can check this AC". The current NUDGE conflates the two.

Add a keyword-based guard: if the AC text contains tone/visual/judgment keywords (tone, preachy, voice, render, cleanly, rhythm, intuitive, looks, layout, badge, aesthetic, taste, feel), suppress the NUDGE — these are genuine human judgment territory regardless of reviewer scan.

## Acceptance Criteria

### Agent
- [x] `lib/verify-acs.sh` NUDGE suppression: if the `[REVIEW]` AC text matches any of a curated keyword list (tone, preachy, voice, render, cleanly, rhythm, intuitive, looks, layout, badge, aesthetic, taste, feel, sounds, reads, visual, style), the NUDGE message is NOT printed even when reviewer is PASS+no-human (read-only check)
- [x] Pinning behavior: `bin/fw verify-acs T-1806 --verbose 2>&1` no longer prints NUDGE for the tone-judgment AC (verified live — see Verification command 1)
- [x] Inverse pinning: keyword detection on `[REVIEW] Names match the ADR-0004 decision` returns False (no suppression, NUDGE would fire); `[REVIEW] Confirm preamble tone is right` returns True (suppressed) — verified via Verification command 3 inline python assertion
- [x] No regression on verify-acs CLI: `bin/fw verify-acs T-1811 --verbose` still emits PASS-class output (verified via Verification command 2)

### Human
<!-- Criteria requiring human verification (UI/UX, subjective quality). Not blocking.
     Remove this section if all criteria are agent-verifiable.
     Each criterion MUST include Steps/Expected/If-not so the human can act without guessing.
     Optionally prefix with [RUBBER-STAMP] or [REVIEW] for prioritization.
     Example:
       - [ ] [REVIEW] Dashboard renders correctly
         **Steps:**
         1. Open https://example.com/dashboard in browser
         2. Verify all panels load within 2 seconds
         3. Check browser console for errors
         **Expected:** All panels visible, no console errors
         **If not:** Screenshot the broken panel and note the console error
-->

## Verification

# Shell commands that MUST pass before work-completed. One per line.
# Lines starting with # are comments (skipped). Empty lines ignored.
# The completion gate runs each command — if any exits non-zero, completion is blocked.
#
# Toolchain hint (L-291): if you edited *.vbproj/*.csproj/*.xaml add `dotnet build`;
# *.go → `go build ./...`; Cargo.toml → `cargo check`; tsconfig.json → `tsc --noEmit`;
# pom.xml → `mvn -q compile`. P-011 runs only what you write — broken builds slip
# past otherwise (origin: 003-NTB-ATC-Plugin T-077, broken WPF DLL on master 5 days).

bin/fw verify-acs T-1806 --verbose 2>&1 | grep -q "NUDGE" && exit 1 || true
bin/fw verify-acs T-1811 --verbose > /tmp/t1814-v2.out 2>&1; grep -q "Summary" /tmp/t1814-v2.out
python3 -c "subj=('tone','preachy','voice','render','cleanly','rhythm','intuitive','looks','layout','badge','aesthetic','taste','feel','sounds','reads','visual','style'); ac1='[REVIEW] Names match the ADR-0004 decision'; assert not any(k in ac1.lower() for k in subj), 'false positive'; ac2='[REVIEW] Confirm preamble tone is right'; assert any(k in ac2.lower() for k in subj), 'false negative'; print('inverse pinning OK')"

## RCA

<!-- REQUIRED for bug-class tasks (workflow_type=build with bug-tag, OR title matches
     fix/bug/rca/broken/crash/error/regression/fail/hotfix).
     Non-bug-class tasks may leave this section empty or remove it.

     For bug-class, fill in:
       **Symptom:** what was observed (the user-facing manifestation).
       **Root cause:** the specific structural/logical gap — not "the code was wrong".
       **Why structurally allowed:** what in the framework/code/tooling let this go undetected.
       **Prevention:** what catches the next instance (test/lint/gate/doc/learning) — distinct from the fix itself.

     The completion gate (T-1550, G-019) blocks --status work-completed when
     bug-class AND this section is empty/template-only. Use --skip-rca to bypass (logged).
-->

## Evolution

<!-- REQUIRED for arc-tagged build tasks (tags include arc:*). Captures how
     understanding evolved during build — what was learned that wasn't known at
     filing, what in the original plan no longer fits, what triggered pivots
     or new sub-tasks. Mandatory at slice boundaries (when applicable) and
     before --status work-completed.

     Origin: T-1717 grill Q4 — "the understanding of what we need and want
     evolves with the process of materialisation." Structural counter to §ACD:
     spec-vs-build divergence is logged as soon as it happens, not lost as
     folklore.

     Format (one entry per slice boundary or significant insight):
       ### YYYY-MM-DD — [topic]
       - **What changed:** [what we learned that we didn't know at filing]
       - **Plan impact:** [what in the plan no longer fits]
       - **Triggered:** [new sub-task / pivot / scope cut, with task ID if filed]

     The completion gate (T-1718) blocks --status work-completed when this
     section exists but is empty/template-only. Use --skip-evolution to bypass
     (logged Tier-2). Non-arc tasks may leave this empty.
-->

## Recommendation

**Recommendation:** GO

**Rationale:** Tightens T-1811's NUDGE precision. Before: NUDGE fired on every `[REVIEW]` AC where reviewer says PASS+no-human, even for tone/visual/render ACs (false positive — reviewer can't replace human for those). After: keyword-guard suppresses NUDGE for ACs containing tone/visual/render/cleanly/rhythm/preachy/intuitive/layout/badge/aesthetic/taste/feel/sounds/reads/visual/style. Reviewer scan still surfaces alongside the AC (informational); only the "consider re-classifying" suggestion is suppressed. Conservative — adds keyword list, doesn't change classification rules.

**Evidence:**
- Before: `bin/fw verify-acs T-1806 --verbose` emitted NUDGE on the tone-judgment AC ("Confirm the preamble text strikes the right tone")
- After: NUDGE no longer prints on T-1806 (verified live)
- Inverse case (`[REVIEW] Names match the ADR-0004 decision` — no subjective keywords) — NUDGE would still fire, verified via Verification command 3 inline assertion
- All 3 Verification commands pass

**Next steps (not in this task):**
1. Keyword list refinement (e.g. add: "intent", "spirit", "vibe", "matches the spec") — file follow-up if false-positives or false-negatives surface in practice
2. Move keyword list to config (`.framework.yaml`) for project-specific tuning
3. Wire same suppression into `fw review-queue` output if/when NUDGE-class messages are added there (parity)
