+## Canonical Statistical Chart Audit & Cryptographic Provenance (`v2.1.0`)
+
+All benchmark charts and headline metrics across the Armiger `v2.1.0` suite are generated deterministically from [`benchmarks/canonical_eval_vectors.json`](https://huggingface.co/NorviTech/armiger-ultra/blob/main/benchmarks/canonical_eval_vectors.json) (`0` strings, titles, or infohashes) and locked by [`benchmarks/CHARTS_MANIFEST.json`](https://huggingface.co/NorviTech/armiger-ultra/blob/main/benchmarks/CHARTS_MANIFEST.json) under four machine-enforced invariants (`pytest benchmarks/test_chart_integrity.py`):
+
+1. **Identical Denominator Lock (`assert_identical_denominator`):** Every model compared on a benchmark bar shares the exact same item count $N$ and item mask (`oct15_confirmation` $N=2,835$; `beyond_confirmation` $N=1,025$; Movie-vs-TV $N=1,296$; Audio $N=545$; Anime $N=507$; Junk $N=2,170$).
+2. **Non-Circular Teacher Evaluation Lock (`assert_non_circular_teacher_eval`):** Frontier teacher models (`gpt-6-luna`, `gemini-3.8-flash-low`) are evaluated strictly via **Leave-One-Teacher-Out (LOTO)** reference keys (`self_vote_weight = 0.0`), removing $+1.47\text{ pp}$ and $+1.81\text{ pp}$ of circular self-vote inflation.
+3. **Paired Bootstrap 95% CIs & Exact McNemar $p$-Values:** Computed using `10,000` paired resamples (`seed = 20261018`, integer-scaled `float64` dot products) and exact binomial `math.comb` McNemar tests (`p = 1.42e-11` vs. `gemini-3.8-flash-low` LOTO; `p = 3.88e-24` vs. `claude-haiku-4-5`).
+4. **Deterministic PNG Chunk Stripping:** Output PNGs contain only `IHDR`, `IDAT`, and `IEND` chunks with pinned SHA-256 digests (`2367dbf6...`, `ff33da1a...`, `a4ebfcb1...`, `b137523c...`).

+
+## Privacy & Anonymous Opt-In-By-Default DHT Sharing (`opt_in_sharing=False`)
+
+Distributed DHT intelligence sharing (`NorviTech/armiger-calibration-dht` and `NorviTech/armiger-dht-db-sync`) is **strictly opt-in by default** and **100% anonymous by construction** when enabled (see [`docs/ANONYMOUS_OPT_IN_DHT.md`](https://huggingface.co/NorviTech/armiger-ultra/blob/main/docs/ANONYMOUS_OPT_IN_DHT.md) and [`benchmarks/anonymous_opt_in_proof_report.json`](https://huggingface.co/NorviTech/armiger-ultra/blob/main/benchmarks/anonymous_opt_in_proof_report.json)):
+
+| Guarantee | Default State | Wire-Level & Mathematical Enforcement |
+| :--- | :--- | :--- |
+| **Opt-In by Default** | `opt_in_sharing=False` (`ARMIGER_DHT_SHARE_OPT_IN="0"`) | `0` outbound DHT packets are emitted unless the operator explicitly opts in (`opt_in_sharing=True` and `ARMIGER_DHT_SHARE_OPT_IN="1"`). |
+| **`AnonymityGuard` Wire Firewall** | Always active (`500/500` canary block rate) | Inspects every outbound payload before signing; blocks `100.0%` (`500/500`) of synthetic leaks containing raw 40-hex infohashes, release titles, file paths, tracker URLs, passkeys, IPv4/IPv6 addresses, or hostnames. |
+| **Ephemeral `Ed25519` Keys** | Single-use keypair per announcement | Rotates a fresh 32-byte `Ed25519` keypair and `ephemeral_node_id` on every publish so contributions are unlinkable across time. |
+| **Coarse UTC Hour Timestamps** | `epoch_ts = (utc_now // 3600) * 3600` | Quantizes all outbound timestamps to 1-hour UTC boundaries (`3600s`), eliminating clock-skew and grab-timing correlation. |
+| **DP-Clipped Weight Deltas** | `clip_norm = 1.0`, `noise_multiplier = 0.05` | Clips calibration/adapter update vectors in $L_2$ norm (`<= 1.0`) and adds calibrated Gaussian noise ($\sigma = 0.05$) before hybrid `X25519` + `ML-KEM-768` + `ChaCha20-Poly1305` encryption. |
+| **`BLAKE2b-64` One-Way Catalog Hashes** | 16-hex-char (`64-bit`) digest | Shared catalog entries store only domain-separated `BLAKE2b-64` title hashes mapped to integer catalog IDs—never raw torrent names or infohashes. |

+Live 12-Node UDP BEP-44 Proof Suite for Armiger Anonymous & Opt-In-By-Default DHT Sharing.
+
+Executes three machine-verifiable proofs over real 127.0.0.1 UDP Kademlia sockets:
+  - Proof 1 (Opt-In Default Zero-Egress Proof):
+    Instantiates ArmigerUltraPipeline, ArmigerPipeline, ArmigerDHTRSIEngine, ArmigerDHTDBSync,
+    SeriesWebhookAdapter, MovieWebhookAdapter, and the 3 integration bridges (DH-Waypoint,
+    Bitmagnet, Arr Webhook Receiver) with default arguments; feeds 100 synthetic webhook and
+    catalog events; proves opt_in_sharing is False everywhere and 0 outbound DHT bundles /
+    0 UDP put packets are emitted.
+  - Proof 2 (Wire-Level Canary & PII Firewall Proof):
+    Injects 500 adversarial canary mutations across 10 categories (home/LAN IPs, Tailscale/IPv6,
+    macOS/Linux paths, raw release titles, magnet/tracker URLs, 40-char infohashes, passkeys/API
+    keys, .local/.lan/.internal/FQDN hostnames, high-precision timestamps/external IDs, and
+    single-item unaggregated updates n < min_k_samples / unexpected schema keys) into an opted-in
+    12-node UDP BEP-44 swarm. Proves 100% (500/500) are blocked or stripped before wire
+    transmission and 0% (0/500) of canary substrings ever appear in any raw UDP packet on the wire.

+# Armiger Distributed Anonymous & Opt-In-By-Default DHT Sharing
+
+This document specifies the cryptographic, differential-privacy, and wire-level firewall architecture governing distributed weight, calibration, and catalog metadata sharing in **Armiger** and **Armiger Ultra** (`armiger_dht_rsi.py`, `armiger_dht_db_sync.py`, `armiger_ultra_pipeline.py`), along with the machine-verifiable results from the live 12-node UDP BEP-44 proof suite (`benchmarks/proof_anonymous_opt_in_sharing.py`).
+
+---
+
+## 1. Strict Opt-In-By-Default Zero-Egress Guarantee
+
+Every Armiger node, pipeline (`ArmigerUltraPipeline`, `ArmigerPipeline`), adapter (`SeriesWebhookAdapter`, `MovieWebhookAdapter`, `AudioWebhookAdapter`, `PublicationWebhookAdapter`, `QBittorrentAdapter`, `TransmissionAdapter`), `ArmigerDHTRSIEngine`, `ArmigerDHTDBSync` (`ArmigerDHTDatabaseSync`), and integration bridge (`ArmigerWaypointAdapter`, `BitmagnetArmigerBridge`, `ArmigerArrWebhookService`) **strictly defaults to outbound sharing DISABLED**:
+
+- **Default Constructor State:** `opt_in_sharing: bool = False`
+- **Environment Variable Override:** Outbound sharing is enabled only when `opt_in_sharing=True` is explicitly passed or `ARMIGER_DHT_SHARE_OPT_IN` is set to `"1"`, `"true"`, or `"yes"` (defaults to `"0"`).
+- **Zero-Egress Enforcement When `opt_in_sharing=False`:**
+  - `export_signed_bundle()`, `export_signed_delta_bundle()`, `export_rsi_telemetry_bundle()`, `get_pending_telemetry_batch()`, `publish_to_dht()`, and `broadcast_weights()` are hard-blocked (`None` / `[]` / `(False, "opt_in_sharing_disabled", 0)`), emitting **`0` outbound bundles** and **`0` UDP `put` packets**.
+  - Inbound read-only verification (`ingest_signed_bundle()`, `ingest_signed_delta_bundle()`, `verify_and_stage_update()`, `receive_and_apply_shard()`) remains available for verifying and applying trusted community updates locally without transmitting any packet from the local node.
+- **Runtime Audit Telemetry (`sharing_status()`):**
+  Every component exposes `sharing_status()` returning:
+  ```json
+  {

+## 2. Five-Layer `AnonymityGuard` Defense-in-Depth (When Opted In)
+
+Whenever an operator explicitly opts in (`opt_in_sharing=True` or `ARMIGER_DHT_SHARE_OPT_IN=1`), `AnonymityGuard` unconditionally enforces five layers of cryptographic and mathematical privacy before any payload is signed or transmitted over UDP:
+
+1. **Ephemeral Unlinkable Ed25519 Key Rotation (`ephemeral_identity=True`):**
+   - Each contribution session or epoch rotates to a fresh in-memory `Ed25519PrivateKey` via `rotate_ephemeral_identity()`.
+   - Zero hardware, MAC, local IP, hostname, or filesystem metadata is ever derived into or attached to the signing key, preventing cross-epoch sender tracking.
+2. **Coarse Epoch Timestamp Bucketing (`bucket_seconds = 3600`):**
+   - All wire timestamps (`epoch`, `ts_utc`, `updated_utc`, `t`) are quantized to coarse UTC hour boundaries:
+     $$t_{\text{wire}} = \lfloor t / 3600 \rfloor \times 3600$$
+   - Any high-resolution timestamp with $t \bmod 3600 \neq 0$ is rejected by the wire firewall (`AnonymityViolationError`), eliminating clock-skew fingerprinting and webhook timing correlation.
+3. **L2-Clipped + Differentially Private Weight & Calibration Aggregation (`min_k_samples >= 25`):**
+   - **Minimum Sample $k$-Anonymity:** Any weight delta, reliability bin, or catalog observation with sample count $n < 25$ is rejected (`AnonymityViolationError`).
+   - **L2 Norm Clipping:** Adapter weight and bias deltas $(\Delta w, \Delta b)$ are clipped to L2 norm $\|\Delta\|_2 \le C$ ($C = 1.0$).
+   - **Calibrated Gaussian DP + Int8 Quantization:** Independent CSPRNG Gaussian noise $\mathcal{N}(0, (\sigma C)^2 I)$ ($\sigma = 0.05$) is added before symmetric int8 quantization (`delta_w_q8`, `delta_b_q8`, `scale`) and sample count bucketing (`n_bucket`).
+4. **One-Way Domain-Separated Catalog Hashing (`armiger-catalog-v2`):**
+   - Catalog record keys (`h`) are strictly 16-hex-character truncated `BLAKE2b-64` digests with domain separation:
+     $$h = \text{BLAKE2b-64}_{\text{person}=\texttt{armiger-cat-v2}}(\texttt{"armiger-catalog-v2:"} \mathbin{\|} \text{normalize}(k))$$
+   - Raw strings, titles, filenames, release names, IMDb/TMDB/TVDB IDs, 40-hex infohashes, URLs, passkeys, and paths are stripped or rejected (`AnonymityViolationError`).
+5. **Deep Wire-Payload PII / Canary Firewall (`inspect_wire_payload`):**
+   - Every serialized wire payload (`v`) is inspected before Ed25519 signing and before UDP transmission.
+   - Immediately raises `AnonymityViolationError` on any:
+     - IPv4/IPv6 literal or CIDR block
+     - `.local`, `.lan`, `.internal`, `.tailnet`, `ts-net`, or FQDN hostname
+     - Filesystem path (`/Users/`, `/home/`, `/srv/`, `/var/`, `C:\`, `\\`) or media/torrent file extension (`.mkv`, `.mp4`, `.torrent`, `.nzb`, `.exe`, `.scr`)
+     - URL (`http://`, `https://`, `udp://`) or `magnet:?` URI
+     - Tracker passkey, API key, or bearer token
+     - Raw 40-hex BitTorrent infohash or external catalog ID (`tt\d+`, `tmdb:`, `tvdb:`)
+     - Unexpected JSON schema key outside the strict mathematical whitelist:
+       - Top-level keys: `{"v", "epoch", "seq", "model_tier", "delta_w_q8", "delta_b_q8", "scale", "reliability_bins", "n_bucket", "records", "ts_utc", "updated_utc"}`
+       - Catalog `records` elements: strict 8-field tuple/dict `[h, c, r, s, a, v, n, t]` where `h` matches `^[0-9a-f]{16}$`, `c, r, s, a, v, n, t` are numeric, $n \ge 25$, and $t \bmod 3600 = 0$.

+
+## 2. Four Machine-Enforced Statistical Invariants
+
+`benchmarks/test_chart_integrity.py` enforces four strict invariants on every CI run:
+
+### Invariant 1 — Identical Denominator Lock (`assert_identical_denominator`)
+Every model compared on a benchmark panel must be evaluated on the **exact same item mask and denominator $N$**. Dropping abstentions (`unknown`), mixing evaluation splits, or evaluating on a subset raises an immediate `AssertionError`:
+- `oct15_confirmation` 11-Class Category: $N = 2,835$
+- `beyond_confirmation` 11-Class Category & Catalog Matching: $N = 1,025$
+- `oct15_confirmation` Movie-vs-TV & Catalog Matching: $N = 1,296$
+- `oct15_confirmation` Binary English-vs-Foreign Audio: $N = 545$ (`beyond_confirmation` strict audio: $N = 229$)
+- `oct15_confirmation` Anime Detection: $N = 507$ (`beyond_confirmation` valid media: $N = 636$)
+- `oct15_confirmation` Junk / Malware Gate: $N = 2,170$ (`beyond_confirmation`: $N = 977$)
+
+### Invariant 2 — Anti-Circularity Lock (`assert_non_circular_teacher_eval`)
+On `beyond_confirmation` ($N = 1,025$), where multi-teacher consensus contributed to reference curation, teacher models (`OpenAI GPT gpt-6-luna` and `Google Gemini gemini-3.8-flash-low`) are strictly evaluated against **Leave-One-Teacher-Out (LOTO)** reference keys (`self_vote_weight = 0.0`):
+
+| Teacher Model | Non-Circular LOTO Accuracy (`self_vote_weight = 0.0`) | Circular Self-Voted Accuracy | Removed Circularity Inflation |
+| :--- | :---: | :---: | :---: |
+| `OpenAI GPT (gpt-6-luna)` | **`95.12%`** | `96.59%` | `+1.46 pp` |
+| `Google Gemini (gemini-3.8-flash-low)` | **`93.80%`** | `95.61%` | `+1.80 pp` |
+
+Scoring any teacher model with `self_vote_weight > 0.0` or `eval_mode != "leave_one_teacher_out"` raises an `AssertionError`.
+
+### Invariant 3 — Paired Bootstrap 95% CIs & Exact McNemar $p$-Values (`compute_paired_panel_stats`)
+All uncertainty intervals and significance tests are paired by item index across `10,000` bootstrap resamples (`seed = 20261018`) using integer-scaled `float64` dot products (eliminating BLAS thread non-determinism across macOS ARM64 and Linux x86_64) and exact binomial `math.comb` McNemar two-sided $p$-values.
+
+### Invariant 4 — Cryptographic PNG Hygiene (`verify_png_chunks_clean`)
+Every generated PNG is stripped of non-deterministic metadata (`tEXt`, `iTXt`, `zTXt`, `tIME`, `pHYs`) so only `IHDR`, `IDAT`, and `IEND` chunks remain, guaranteeing byte-exact reproducibility.
