Subject: [PATCH] Add per-deployment adaptive optimization + VEIL npm
 metaharness (ADR-289)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two additions on top of the hyper-optimized VEIL shield.

1) Adaptive optimization (v2/crates/wifi-densepose-privshield/src/optimize.rs):
   - optimal_bits_across_snr / model_optimal_bits_for_snr: the throughput-
     optimal feedback resolution shifts with SNR (unconstrained optimum 4 bits
     at 5-10 dB, 3 bits at 20-40 dB); within the spec {5,7,9} set it stays 5,
     which is why the shipped shield is SNR-stable.
   - adaptive_shield / min_passes_for_n: derive a shield for a specific
     deployment. Finding: the collapse budget is N-independent in this model
     (48 passes collapses N in {8,64} alike) — it is set by the fine-subspace
     dimension, not the candidate count. Defaults unchanged, so the proof
     witness is untouched. 38 tests + doctest pass; clippy -D warnings clean.

2) npm metaharness harness/wifi-densepose-privshield/ (ADR-289), mirroring
   wifi-densepose-sar-harness (ADR-286) with two improvements:
   - @metaharness/* imported dynamically inside the commands that need them, so
     `guidance` and `--help` run with ZERO dependencies installed (offline / pre
     `npm install`).
   - a dependency-free VEIL `guidance` command: a source-cited, evidence-
     labelled, read-only capability map (topics: overview, threat,
     countermeasure, compliance, optimization, experiment).
   Standard router + flywheel (SYNTHETIC) + Darwin wiring, tailored to VEIL
   task axes and policy levers. Tests: smoke + router + flywheel (need install)
   and guidance (offline). .harness manifest generated with real per-file
   hashes. Validated offline: cli syntax, --help, guidance topics, exit codes,
   graceful degradation when deps are absent.

Docs: research bundle 08 gains a per-deployment adaptivity section; 07 and the
crate README point at the harness; ADR-289 added and indexed.

+# ADR-289: `wifi-densepose-privshield-harness` — a MetaHarness for the VEIL privacy shield
+
+| Field | Value |
+|-------|-------|
+| **Status** | Proposed — implemented (P1) |
+| **Date** | 2026-08-09 |
+| **Parent** | ADR-288 (`wifi-densepose-privshield` / VEIL, the crate this harness assists development on) |
+| **Relates to** | ADR-286 (`wifi-densepose-sar-harness`, the per-crate harness scaffold this one mirrors), ADR-285 (`harness/homecore/`, the WASM-first `@metaharness/kernel` pattern), ADR-182 (`harness/ruview/`, the first minted harness), ADR-282 (L0–L5 evidence ladder) |
+| **Location** | `harness/wifi-densepose-privshield/` |
+
+## 0. PROOF discipline
+
+Every claim below about what is "real" versus "illustrative"/"SYNTHETIC" is
+checked by a test in this harness's own suite (router + flywheel + install-smoke
++ guidance). The dependency-free `guidance` surface is covered by
+`__tests__/guidance.test.ts`, which runs even before `npm install`. Nothing here
+asserts a MEASURED defense result — the harness surfaces the VEIL crate's
+SYNTHETIC/L0 numbers with that label intact.
+
+## 1. Context
+
+`wifi-densepose-privshield` (ADR-288) is the VEIL privacy shield — a new,
+narrowly-scoped crate. Following the pattern ADR-286 set for
+`wifi-densepose-sar`, it gets a dedicated per-crate MetaHarness rather than a
+bespoke setup: the `vertical:coding` scaffold (architect/implementer/reviewer/
+test-writer, `doctor`) with `@metaharness/router`, `@metaharness/flywheel`, and
+Darwin Mode wired in, plus a VEIL-specific, dependency-free `guidance` surface.
+
+## 2. Decision
+
+Land the harness at `harness/wifi-densepose-privshield/`, mirroring
+`wifi-densepose-sar-harness`, with two deliberate improvements:
+
+1. **Dynamic dependency imports.** `bin/cli.js` imports the `@metaharness/*`
+   packages *inside* the commands that need them, not at module top. So
+   `guidance`, `--help`, and the guidance test run with **zero dependencies
+   installed** — useful for offline/air-gapped review and for this repo's CI
+   before `npm install`. Only `init`/`doctor`/`route`/`flywheel` touch the
+   kernel/host/router/flywheel packages.
+2. **A VEIL `guidance` command.** A self-contained, source-cited, read-only
+   capability map (topics: `overview`, `threat`, `countermeasure`,
+   `compliance`, `optimization`, `experiment`), each entry carrying a summary,
+   repo-relative source citations, focused validation commands, and explicit
+   limitations — the `ruview_guidance` shape, specialized to VEIL. It labels all
+   defense evidence `SYNTHETIC/L0` and states plainly that guidance is
+   navigation, not authority.
+
+The standard three self-improvement/cost pieces are wired as real npm
+dependencies (not stubs):
+
+- **`@metaharness/darwin`** (devDependency) — `npm run evolve` / `evolve:dry`
+  mutates the harness's own operating config, keeping only measurable gains.
+- **`@metaharness/router`** — `src/router.ts` wires a real cost-optimal `Router`
+  (`qualityBar: 0.8`, k=1) over two model tiers, with four VEIL-shaped task axes
+  (threatModeling / complianceReview / optimizerTuning / docWriting). Labelled
+  examples are illustrative seed data (honesty note in-file).
+- **`@metaharness/flywheel`** — `src/flywheel.ts` wires the real
+  `runFlywheelGenerations` promotion loop (propose → evaluate → gate → promote,
+  Ed25519-signed, independently replayable) with a SYNTHETIC proposer/evaluator
+  (`dataSource: 'SYNTHETIC'`, no model call), over VEIL policy levers
+  (`complianceReview`, `threatTriage`).
+
+## 3. What this explicitly is NOT
+
+- **Not a VEIL runtime.** The harness does not run a radio, emit RF, or jam. It
+  assists *development* on the crate; it cannot execute the shield on hardware.
+- **Not evolving the crate.** Darwin/Flywheel mutate the harness's own policy
+  (agent prompts, review-checklist depth), not VEIL's Rust code. The crate's
+  actual hyper-optimization (ADR-288 §opt) was done directly, in the crate.
+- **Not a live routing/promotion system.** The router's examples are seed data;
+  the flywheel's proposer/evaluator are deterministic stand-ins — both honestly
+  labelled in-source and in `CLAUDE.md`.
+- **Not a replacement for the crate's gates.** The authoritative check for a
+  VEIL change remains `cargo test -p wifi-densepose-privshield`.
+- **Not a re-labeller.** The harness must never present VEIL's SYNTHETIC results
+  as MEASURED, and never scaffold interference-based ("jamming") defenses — both
+  are hard rules in the harness `CLAUDE.md`.
+
+## 4. Consequences
+
+- The harness ships `guidance`/`doctor`/`init`/`route`/`flywheel`; `guidance`
+  and `--help` work offline (validated here via `node bin/cli.js`), the rest
+  after `npm install` + `npm run build` (CI).
+- `.harness/manifest.json` + `manifest.sha256` are generated with real per-file
+  hashes at creation (unlike ADR-286's scaffold, whose manifest was historical).
+- Scoped to its own name: its plugin, permissions, and (future) MCP surface only
+  read/assist on `wifi-densepose-privshield`. No risk to other harnesses/crates.
+
+## 5. Validation
+
+```bash
+cd harness/wifi-densepose-privshield
+node bin/cli.js guidance --topic overview   # dependency-free
+npm ci && npm run build && npm test          # full suite (CI; needs registry access)
+```

-## 6. Robustness caveats (unchanged from the threat model)
+## 6. Per-deployment adaptivity
+
+The optimum is not one number — `optimize` derives it per deployment:
+
+- **SNR → feedback resolution.** `optimal_bits_across_snr` shows the
+  *unconstrained* throughput-optimal resolution shifting with SNR: **4 bits at
+  5–10 dB, 3 bits at 20–40 dB** (low SNR values fine resolution more because
+  the Shannon capacity is near-linear there, so the residual costs more). Within
+  the spec-allowed {5,7,9} set the choice is 5 bits across this whole range —
+  the residual is already negligible at 5 bits — which is why the shipped shield
+  is SNR-stable.
+- **Identity count → mixing.** `adaptive_shield(base, n)` derives the config for
+  a room with `n` expected occupants. A notable finding: in this model the
+  collapse budget is **N-independent** (min 48 passes collapses N∈{8,64}
+  alike), because a well-mixed Haar-like rotation destroys per-identity
+  structure regardless of how many identities there are — the budget is set by
+  the fine-subspace dimension, not the candidate count. So `adaptive_shield`
+  returns the same 96/5 across that range: the default is robust, not a point
+  tuning.
+
+Both are surfaced through the harness `guidance --topic optimization`.
+
+## 7. Robustness caveats (unchanged from the threat model)
 
 - The collapse is verified against two classifiers and two N; a learned
   attacker on real captures must still be checked (P2/P5).

+  the kernel.
+- Defer destructive operations to the user.
+- **Never present WiFi sensing as camera-grade, and never relabel VEIL's
+  SYNTHETIC/L0 results as MEASURED** — a hardware witness is required first
+  (CLAUDE.md hardware rule; ADR-282 ladder). The harness is a development aid;
+  it does not run a radio and cannot emit RF.
+- VEIL uses compliant waveform controls only — **never jamming.** Do not add,
+  suggest, or scaffold interference-based "defenses."
+
+## Commands
+
+- `init` — boot the kernel + host adapter.
+- `doctor` — verify the install end-to-end (kernel, host, guidance map).
+- `guidance --topic <t> [--query <q>]` — read-only VEIL capability map
+  (dependency-free; topics: `overview`, `threat`, `countermeasure`,
+  `compliance`, `optimization`, `experiment`). Source-cited and
+  evidence-labelled; navigation only, not authority.
+- `route <e0> <e1> <e2> <e3>` — cost-optimal model routing via
+  `@metaharness/router` (needs `npm run build`).
+- `flywheel [generations]` — SYNTHETIC self-improvement demo via
+  `@metaharness/flywheel` (needs `npm run build`).
+
+## Architecture
+
+Uses [@metaharness/kernel](https://www.npmjs.com/package/@metaharness/kernel)
+(Rust-compiled WASM with a NAPI-RS native fallback) so the same code runs on
+every platform. The `@metaharness/*` packages are imported *dynamically* inside
+the commands that need them, so `guidance`/`--help` work with no dependencies
+installed.
+
+### Darwin, router, flywheel
+
+- **Darwin Mode** (`@metaharness/darwin`, devDependency) — `npm run evolve` /
+  `evolve:dry` mutates the harness's own config and keeps only measurable
+  improvements.
+- **Router** (`@metaharness/router`) — `src/router.ts` wires a real cost-optimal
+  `Router` (`qualityBar: 0.8`) over two model tiers. Its labelled examples are
+  illustrative seed data (see the file's honesty note), not measured eval-log
+  observations.
+- **Flywheel** (`@metaharness/flywheel`) — `src/flywheel.ts` wires the real
+  promotion loop (propose → evaluate → gate → promote, Ed25519-signed,
+  independently replayable) with a SYNTHETIC proposer/evaluator
+  (`dataSource: 'SYNTHETIC'`, no model call). A LIVE run needs a real Proposer
+  and Evaluator supplied by the operator — see the file's comments.
+
+## Relationship to the crate
+
+This harness assists development *on* the VEIL crate; it does not replace the
+crate's own gates. The authoritative validation for a VEIL change is still:
+
+```bash
+cargo test -p wifi-densepose-privshield --no-default-features
+cargo clippy -p wifi-densepose-privshield --all-targets -- -D warnings
+```

+# wifi-densepose-privshield-harness
+
+A metaharness (contributor harness) for
+[`wifi-densepose-privshield`](../../v2/crates/wifi-densepose-privshield) — **VEIL**,
+the compliant-waveform WiFi-sensing privacy shield (ADR-288). Defined by ADR-289.
+
+> **Advanced Coding** — architect → implement → review → test, plus a
+> dependency-free VEIL guidance surface. Modeled on `wifi-densepose-sar-harness`
+> (ADR-286). Multi-host scaffold with a kernel that resolves native → wasm → js.
+
+## Install
+
+```bash
+npm install -g wifi-densepose-privshield-harness
+wifi-densepose-privshield-harness doctor
+```
+
+Or run without installing:
+
+```bash
+npx wifi-densepose-privshield-harness guidance --topic overview
+```
+
+## Commands
+
+| Command | Deps needed | Purpose |
+|---|---|---|
+| `init` | kernel + host | Boot the kernel + host adapter |
+| `doctor` | kernel + host | Verify the install end-to-end |
+| `guidance --topic <t>` | **none** | Read-only VEIL capability map (source-cited, evidence-labelled) |
+| `route <e0..e3>` | router + `npm run build` | Cost-optimal model routing |
+| `flywheel [gens]` | flywheel + `npm run build` | SYNTHETIC self-improvement demo |
+
+`guidance` topics: `overview`, `threat`, `countermeasure`, `compliance`,
+`optimization`, `experiment`. It needs no dependencies or build step, so it
+works offline and in CI before `npm install`.
+
+## What VEIL is
+
+VEIL shapes a node's **own** beamforming feedback with keyed Givens rotations so
+a third-party passive sniffer cannot re-identify people, while a keyed receiver
+sees an essentially unchanged link. **Compliant waveform controls only — never
+jamming.** Reference results are **SYNTHETIC / evidence level L0** (reproduced by
+`cargo test`), never MEASURED until a hardware witness exists. See the crate's
+[ADR-288](../../docs/adr/ADR-288-veil-privacy-shield-compliant-waveform.md) and
+[research bundle](../../docs/research/privacy-shield/).
+
+## Darwin, router, flywheel
+
+- `npm run evolve` / `evolve:dry` — Darwin Mode self-mutation of the harness
+  config (`@metaharness/darwin`).
+- `npm run route -- <e0> <e1> <e2> <e3>` (after `npm run build`) — cost-optimal
+  model routing (`@metaharness/router`).
+- `npm run flywheel:dry` — the SYNTHETIC `@metaharness/flywheel` demo
+  (propose → evaluate → gate → promote, signed + independently replayable).
+
+See `CLAUDE.md` and the honesty notes atop `src/router.ts` / `src/flywheel.ts`
+for what is real wiring vs. illustrative/synthetic data.
+
+## Scope
+
+The harness is a **development aid**. It does not run a VEIL radio, does not
+emit RF, and cannot jam. It does not replace the crate's own gates — the
+authoritative check for a VEIL change is `cargo test -p wifi-densepose-privshield`.
