From d4452bbfddf2f80653848eeceaa2279c599fe636 Mon Sep 17 00:00:00 2001 From: gHashTag Date: Tue, 14 Jul 2026 04:17:23 +0000 Subject: [PATCH 01/12] docs: wave iphone-admin + PTT-over-Tri-Net (2026-07-14) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Feasibility study for iPhone → P203 Mini direct connection as: 1. Admin dashboard (network management) 2. Voice PTT walkie-talkie client with Tri-Net as trusted transport. Structure: honesty preface, reality snapshot, 12-item weak-spots heatmap (3 CRITICAL / 9 MAJOR), cited science (Apple/Meshtastic/ Opus/Cisco/ATAK), 4-sprint 8-task decomposed plan, three cooperation lanes (PWA-first / native iTAK / split-brain hedge), trust ledger. Recommendation: Lane A (PWA-first) — covers -sim end-to-end, no App Store dependency, no silicon dependency, cheapest demo. Merge-order: E1.1 topology doc can start now without other PRs merged; E1.2 depends on PR #79 (M2 TUN spec) and #65/#63 (Noise handshake). All pre-silicon numbers tagged -sim. Attestation deferred to post-SKY26b (2026-12-16). Discipline hooks: no-fabricated-metrics, -sim tagging, Trinity rule (no chip no TRI), aspiration-vs-property, numbers-without-realm. phi^2 + phi^-2 = 3 --- docs/WAVE_IPHONE_ADMIN_2026-07-14.md | 234 +++++++++++++++++++++++++++ 1 file changed, 234 insertions(+) create mode 100644 docs/WAVE_IPHONE_ADMIN_2026-07-14.md diff --git a/docs/WAVE_IPHONE_ADMIN_2026-07-14.md b/docs/WAVE_IPHONE_ADMIN_2026-07-14.md new file mode 100644 index 00000000..69c78a21 --- /dev/null +++ b/docs/WAVE_IPHONE_ADMIN_2026-07-14.md @@ -0,0 +1,234 @@ +# Wave · iPhone-admin + PTT-over-Tri-Net · 2026-07-14 + +phi^2 + phi^-2 = 3 + +## 0 · Honesty preface + +Эта волна — **feasibility study**, не implementation.

Note: SHA-1 addition (mod 2^32) is deliberately excluded from the spec because t27's `+` maps to Rust's debug-checked `+` and SHA-1 is overflow-based. Instead the spec exposes the four summands (step_a_term, step_f_term, e, K, W) and the runtime combines them via `.wrapping_add`. This keeps every primitive spec-tested while matching RFC semantics. - specs/admin_status.t27 — attestation state gating (none/hmac/ed25519-sim/ ed25519+chip), uptime clamp, node_id range check, path-byte legality and dot-dot detection. The runtime glue in src/bin/admin_httpd.rs is byte I/O only: TcpListener, TcpStream, thread spawning, HTTP framing, WebSocket frame layer. Every SHA-1 step, every base64 character, every path-byte check comes from generated code. Verified end-to-end against RFC 3174 test vectors ("abc", "", quick-brown-fox), RFC 4648 base64 vectors, and the RFC 6455 §1.3 WebSocket handshake example — 7/7 tests pass. The bin is deliberately built via rustc directly (see smoke script) rather than through the cargo crate root: the workspace lib currently has 106 pre-existing errors in unrelated gen/rust/ modules that block `cargo build --lib`. The bin uses `#[path]` to include only the three new generated modules and needs no other crate code. build.rs incidental fix: the previous version had a type mismatch (`.map_or(0, ...)` chained on integer). Replaced with a simple `mtime()` helper. No behaviour change beyond making the pre-existing regen path actually compile — as a side effect, `cargo` now regenerates gen/rust/etx.rs and gen/rust/multipath_routing.rs correctly (which partially fixes the older `return ()` stub bug). Full fix of the remaining broken generated modules is out of scope for this PR. Also included: - docs/E1_1_IPHONE_TOPOLOGY.md — three-way topology decision (USB Personal Hotspot / iPhone Wi-Fi Hotspot / Board AP), with the primary recommendation, honest -sim limits, and a fallback ladder. - webui/public/index.html — PWA skeleton: tabs (Status/Peers/PTT/Diag), PTT hold-to-talk button (mouse + touch), WebSocket client with auto- reconnect, safe-area insets for iPhone notch. - webui/public/manifest.json — Add-to-Home-Screen manifest. - smoke/e1_1_admin_httpd_smoke.sh — builds bin, launches on 127.0.0.1:18080, curls /api/status, verifies /index.html, does a raw WebSocket upgrade with RFC 6455 test key and checks the accept header matches the value the generated primitives produce. What this does NOT verify (must stay -sim until hardware run): - iPhone tethering to P203 Mini (needs physical devices). - mDNS discovery from an iOS client (needs NSLocalNetworkUsageDescription). - mTLS mutual auth (E2.2, not implemented). - Opus audio pipeline (E3.x, not implemented). - Live neighbor data (needs IPC with trios_meshd — separate PR). phi^2 + phi^-2 = 3 Co-Authored-By: Perplexity Computer --- build.rs | 72 ++--- docs/E1_1_IPHONE_TOPOLOGY.md | 161 ++++++++++ gen/rust/admin_status.rs | 71 +++++ gen/rust/etx.rs | 2 +- gen/rust/multipath_routing.rs | 39 ++- gen/rust/ptt_frame.rs | 125 ++++++++ gen/rust/ws_accept.rs | 118 ++++++++ smoke/e1_1_admin_httpd_smoke.sh | 101 +++++++ specs/admin_status.t27 | 149 ++++++++++ specs/ptt_frame.t27 | 242 +++++++++++++++ specs/ws_accept.t27 | 262 ++++++++++++++++ src/bin/admin_httpd.rs | 511 ++++++++++++++++++++++++++++++++ webui/public/index.html | 380 ++++++++++++++++++++++++ webui/public/manifest.json | 14 + 14 files changed, 2191 insertions(+), 56 deletions(-) create mode 100644 docs/E1_1_IPHONE_TOPOLOGY.md create mode 100644 gen/rust/admin_status.rs create mode 100644 gen/rust/ptt_frame.rs create mode 100644 gen/rust/ws_accept.rs create mode 100755 smoke/e1_1_admin_httpd_smoke.sh create mode 100644 specs/admin_status.t27 create mode 100644 specs/ptt_frame.t27 create mode 100644 specs/ws_accept.t27 create mode 100644 src/bin/admin_httpd.rs create mode 100644 webui/public/index.html create mode 100644 webui/public/manifest.json diff --git a/build.rs b/build.rs index 4aa37b00..89ca0b18 100644 --- a/build.rs +++ b/build.rs @@ -1,51 +1,57 @@ -// build.rs — auto-regenerate from .t27 specs if any changed -use std::process::Command; +// build.rs — auto-regenerate from .t27 specs when a spec is newer than its +// generated .rs sibling.

ArchWiki [iPhone tethering](https://wiki.archlinux.org/title/IPhone_tethering) документирует полный flow — `usbmuxd -f` + trust prompt на iPhone + DHCP client на Linux side. + +**Плюсы:** +- Работает на всех iPhone начиная с iOS 3 (Personal Hotspot появился давно, USB path стабилен). +- Все Yocto/PetaLinux сборки для Zynq имеют kernel option `CONFIG_USB_IPHETH` — включаемо. +- Пользователь просто нажимает «Personal Hotspot» в Settings. +- Zero apple-side coding — iPhone делает host duty. + +**Минусы:** +- iPhone получает **приоритет DHCP** — узел P203 виден как «internet client», а не наоборот. Admin PWA на iPhone должна обращаться к узлу по DHCP-assigned адресу узла (172.20.10.2/3/…), который iPhone контролирует. +- Требует USB-C-to-Lightning или USB-C-to-USB-C кабель (iPhone 15+ имеет USB-C). +- Personal Hotspot требует активной SIM карты в некоторых операторов (не везде — MVNO часто блокируют hotspot). Обход: включить в Airplane mode + Wi-Fi off, тогда tether работает без cell. +- **iOS 14+ NSLocalNetworkUsageDescription:** iPhone Safari разрешает mDNS-browse только с explicit purpose-string prompt. См. [Apple Local Network Privacy FAQ](https://developer.apple.com/forums/thread/663858). + +**Compatibility:** iPhone 12 и новее ✅ (все имеют Personal Hotspot).

Не документировано Apple, работает эмпирически. + +**Плюсы:** +- P203 контролирует IP-план: iPhone получает адрес из mesh-плана (например 10.42.0.5/24), напрямую маршрутизируется в TUN interface `trios_meshd`. +- Не требует iPhone Personal Hotspot (не потребляет cellular data). + +**Минусы:** +- Требует **custom usbmuxd build** на Yocto — не в mainline. Support-cost на каждом OS-upgrade. +- Не документировано Apple → может сломаться с любой iOS версией. +- **iOS не запускает DHCP client автоматически** для USB Ethernet без Personal Hotspot mode — работает только если iOS считает link «Ethernet-like» через специфичный USB class descriptor. +- Требует изменения PetaLinux root filesystem — не «включи и пользуйся». + +**Verdict: FALLBACK на будущее.** Не для v0.1.

All new logic lives in t27 specs; runtime is byte I/O (waiter, not oracle). Every hardware-bound claim stays -sim until it clears the four-stage ratchet. E1.2 — live neighbors via IPC (sandbox verified) - trios_meshd writes /tmp/trinet--status.json atomically (.tmp + rename) every third HELLO tick. Path overridable via TRINET_STATUS_PATH. - admin_httpd tails the status file, extracts the neighbors array with a balanced-bracket scan, gates freshness at 30 s (unix_time delta), exposes GET /api/neighbors and pushes {"type":"neighbors",...} on the /ws socket. - Regression gate smoke/e1_2_ipc_smoke.sh — 6/6: empty, valid, stale, torn, status/neighbors coexistence, path-traversal guard (curl --path-as-is). - New admin_httpd unit tests: b64_decode roundtrip + garbage-reject, JSON field extractor, IPC parser (missing file, valid file). 16/16 pass. E1.3 — mDNS wire skeleton - specs/mdns_wire.t27 (228 lines) — RFC 6762/6763 primitives: TYPE_A/PTR/TXT/ SRV, FLAGS_ANNOUNCE 0x8400, CACHE_FLUSH_BIT, TTL_SHARED_S=4500, TTL_UNIQUE_S=120, u16/u32 BE byte extractors, 11 in-spec tests. - Gen at gen/rust/mdns_wire.rs (spec verified). Responder runtime deferred to a separate PR. A2 — device-DNA challenge/response (Ratchet stage 1 of 4, -sim) - specs/device_dna.t27 (223 lines) — Xilinx DNA_PORT primitive, 7-series DNA_BITS=57, UltraScale=96, nonce 16 B, transcript 33 B, Ed25519 sig 64 B (payload only, sig itself is a placeholder in sim), clock skew ±30 s. - src/bin/attest_dna.rs — TCP verifier on :9601 (bind overridable), 5 unit tests pass. Sim DNA is 0xA57B_0000 + node_id, sig is a deterministic FNV-variant of the transcript. NOT Ed25519 yet. - smoke/a2_attest_dna_smoke.sh — 4/4: two-node fresh-challenge distinct DNA, stale-challenge replay-guard, signature divergence across nodes. - Ratchet: sim only. Stages 2 (Vivado synth), 3 (one P203 Mini), 4 (two boards, cross-replay) remain open. Must land before 2026-10-01 silicon freeze to enter SKY26b tape-out 2026-12-16. E3.1 — PTT audio-frame envelope - specs/ptt_audio.t27 (171 lines) — 9-byte header (version=1, session_id BE u32, seq BE u16, opus_len BE u16), OPUS_MIN_LEN=3, OPUS_MAX_LEN=512, FRAME_DURATION_MS=20, mesh_forward_safe predicate. 7 in-spec tests. - admin_httpd audio_frame_verdict validates envelope, returns audio-ack {accepted, reason, session_id, seq, opus_len}. Does NOT decode Opus and does NOT forward to mesh — that stays E3.2 territory. - PWA MediaRecorder captures 100 ms chunks on PTT press, base64-encodes and ships over WebSocket as {"type":"audio","payload":"..."}. Runtime clamps opus_len to spec bounds. - smoke/e3_1_audio_frame_smoke.sh — 4/4: valid frame accepted, bad version / size mismatch / opus_len 2 all rejected with the spec-mandated reason. - Tolerant JSON parser: extract_json_string_field now accepts both `"payload":"x"` and `"payload" : "x"`. Compact-form matcher for the top-level "type" so Python-style json.dumps output is not silently ignored. Honesty check - All spec predicates: spec verified (t27 parse + gen-rust clean). - All 4 smokes: sandbox verified on this host. - 16 admin_httpd + 5 attest_dna unit tests: sandbox verified. - A2 chip-attest binding: -sim. Silicon (Xilinx DNA_PORT on P203 Mini) NOT read. Ratchet 1/4. - mDNS responder runtime: not yet written. - Audio does NOT forward to mesh. Opus not decoded. E3.2 territory. - No fabricated metrics.

Waits on ssdm4 macbook / CI. - smoke/a2_ratchet_2_synth_smoke.sh — surfaces toolchain state as first-class artifact rather than silent gap. E3.2 audio wire: - src/bin/audio_forwarder.rs — new binary. Listens TCP :9701, validates each envelope with ptt_audio.t27 predicates (version_valid, opus_len_valid, total_frame_len, mesh_forward_safe), UDP-fans accepted frames to AUDIO_FWD_PEERS. Optional AUDIO_FWD_STATS_PORT plaintext endpoint. 7/7 unit tests. - src/bin/admin_httpd.rs — on audio-ack accepted:true, lazily writes the raw frame bytes to AUDIO_FWD_ADDR via a persistent TCP sink. Best-effort: write errors drop the socket and re-connect on the next accepted frame. 16/16 admin_httpd unit tests still pass. - webui/public/index.html — WebCodecs AudioEncoder path added. Prefers real Opus (48kHz mono 24kbps 20ms frames) via AudioWorklet + AudioEncoder. Falls back to MediaRecorder container-blobs on older Safari. Both paths share buildAudioFrame → base64 → WebSocket sink. - smoke/e3_2_opus_mesh_smoke.sh — 6/6 checks. 3 valid frames give frames_in=3 frames_ok=3 forwarded=3 bytes_forwarded=267; UDP listener on :9711 sees 3 frames / 267 bytes; invalid version bumps reject_version. E1.3 responder (zov cherez vozdukh): - src/bin/mdns_responder.rs — UDP :5353 mDNS responder. Joins 224.0.0.251 best-effort, answers PTR queries for _trinet-admin._tcp.local with PTR+SRV+TXT+A. Preserves txid, sets FLAGS_ANNOUNCE=0x8400, cache-flush bit on unique records, TTL 4500 (shared) / 120 (unique) per RFC 6762 §10. Env knobs: TRINET_NODE, MDNS_BIND, MDNS_HOSTNAME, MDNS_ADMIN_ADDR. 7/7 unit tests. - smoke/e1_3_mdns_responder_smoke.sh — 6/6 checks. Reply preserves txid 0xBEEF, flags 0x8400, an-count 4, admin IP octets present, foreign service _printer._tcp ignored.

Prior code silently returned None on any 0xC0 byte, dropping iPhone Bonjour multi-question packets that compress the suffix. - Added read_name() helper with 32-hop limit, visited-offset guard, and 255-octet total-name cap (RFC 1035). - New tests: parse_accepts_compressed_qname, parse_rejects_out_of_bounds _pointer, parse_rejects_pointer_loop. 10/10 unit green. - Existing smoke e1_3_mdns_responder_smoke.sh still 6/6. Weak-point #8 — audio_forwarder replay (CRITICAL): - src/bin/audio_forwarder.rs: added ReplayGuard (RFC-6479-style, per session_id, 64-bit sliding-window bitmap, 16-bit wrap-around aware). - handle_conn now checks replay before UDP fan-out; new stats field reject_replay=N. - New tests: replay_first_frame_accepted, replay_exact_duplicate_rejected, replay_monotonic_seq_accepted, replay_within_window_accepted_once_only, replay_too_old_rejected, replay_isolated_per_session, replay_wrap_around, extract_session_seq_layout. 15/15 unit green. - New smoke smoke/e3_2_replay_smoke.sh — 4/4 checks; N=5 runs back-to-back all pass (deterministic gate per skill v1.3 rule). Non-claims: - No hardware verification; both fixes are runtime-only, sandbox-verified. - ReplayGuard is application-layer replay defense only; sender authentication belongs in future specs/audio_crypto.t27 (ChaCha20-Poly1305 + X25519) — planned as W3 in next wave. - No changes to A2 ratchet 2/4 in this commit; that is still BLOCKED-toolchain-required per prior report. Docs: - docs/W7_WEAK_POINTS_COMPETITORS_2026-07-14.md — full audit: 8 weak points classified by severity + trust class, 3 competitor axes cited from primary sources (SACHa DATE'19, PUFatt DAC'14, Guajardo CHES'07, Papalamprou arXiv:2506.21073, Reticulum LXST, RFC 8766), 8-workstream plan with acceptance criteria, 3 collab options (parallel/by-layer/ sequential-with-gates) with cost estimates. Recommendation: sequential-with-gates given 78 days to silicon freeze 2026-10-01. - docs/ITERATION_LOG.md — created with two entries for 2026-07-14 wave. Discipline: - Anti-anchor: every number in the audit doc carries an explicit trust class (sandbox verified / structural / cited / conjecture).

Closes the six workstreams that were queued in the W7 part-2 audit doc. W3 — audio_crypto envelope spec + reference runtime. - specs/audio_crypto.t27: 199-line spec-first envelope layout (version, nonce, ciphertext, MAC-tag) with predicates and eight tests. Cites RFC 7539, RFC 7748, RFC 8439, Reticulum LXST. Non-claim section states the runtime uses PLACEHOLDER primitives. - gen/rust/audio_crypto.rs: reference runtime tagged -crypto-placeholder. XOR keystream + SHA-256-truncated MAC (pure Rust, no deps). SHA-256 verified against RFC 6234 vector "abc". 17/17 unit tests: constants, arithmetic, envelope gate, nonce layout, wrap/unwrap roundtrip, wrong-key rejection, bit-flip rejection in ct and tag, bad-version rejection, distinct nonces produce distinct ciphertexts, SHA-256 vectors. - Explicitly NOT suitable for adversarial deployment; must be replaced with audited chacha20poly1305 + x25519_dalek (or FIPS-compliant crate audited on ssdm4) before shipping. W4 — dna_reader.v ifdef SYNTHESIS + synth_yosys.sh -DSYNTHESIS. - fpga/attest/dna_reader.v: added (* blackbox *) DNA_PORT declaration gated by `ifdef SYNTHESIS`. Lets yosys openXC7 preserve the primitive through synth_xilinx -family xc7. iverilog sim continues to use sim/dna_port_model.v behavioural stand-in (SYNTHESIS undefined). - fpga/attest/scripts/synth_yosys.sh: pass -DSYNTHESIS via read_verilog. Ratchet 1/4 (iverilog): still 6/6 PASS. Ratchet 2/4 (yosys): unblocked structurally; still BLOCKED-toolchain in this sandbox because yosys is not installed here, but will run cleanly on any host that provides yosys 0.35+ with the Xilinx flow. W5 — anti-anchor cleanup on A2_RATCHET_2_SYNTH.md. - Retracted the "< 50 LUTs and 100 FFs" line as unmeasured. Replaced with a placeholder that explicitly cites the numbers-without-realm- check discipline from tri-net-m2-m4-workflow skill v1.2. The exact count must be filled in when ratchet 2/4 completes on ssdm4 (or on any host with Vivado / yosys). W6 — mDNS multi-question support (qdcount > 1). - src/bin/mdns_responder.rs: new parse_all_questions() iterates over qdcount questions (bounded at 64 as DoS guard) using the compressed- name parser from W1. parse_first_question is now a thin wrapper. - handle_query now scans every question for want_ptr / want_srv / want_a, so Apple-style batched (A + AAAA + PTR) packets are answered correctly. Previously the responder gave up on the first non-matching question. - 5 new tests: two-of-two roundtrip, three-question Apple style, truncated-second rejected, DoS guard (qd=65 rejected), handle_query answers second-of-batch. 15/15 unit green (was 10). Existing smoke e1_3_mdns_responder_smoke.sh still 6/6. W7 — RFC 8766 Discovery Proxy skeleton. - docs/W7_DISCOVERY_PROXY_SPEC.md: spec-first document. Wire layout for overlay proxy queries and replies, predicates, minimum acceptance criteria, non-claims (this is NOT a complete RFC 8766 implementation), what is deferred. Cites RFC 8766, RFC 8765, Apple Bonjour, Mist Bonjour Gateway, Avahi. - src/bin/mdns_proxy.rs: envelope wrap/unwrap for ProxyQuery and ProxyReply, framed I/O helpers (read/write with 8 KiB cap), predicates. 13/13 unit tests. End-to-end runtime (two-process smoke, trios_meshd integration, audio_crypto wrapping) explicitly deferred to a later wave. W8 — Proof of FPGA whitepaper v0. - docs/PROOF_OF_FPGA_WHITEPAPER_v0.md: 10-section, 145-line document. Abstract + threat model (T1-T6, three defended + three explicitly not defended) + non-claims + construction (§4.1 device DNA, §4.2 bitstream attestation citing SACHa, §4.3 PUF citing Guajardo, §4.4 KDF) + mesh integration + monetization (5 revenue paths) + ratchet discipline + honest current status snapshot (A1 done, A2 partial, A3-A5 pending) + what v0 does not cover + full bibliography.

A Proof of FPGA is a cryptographic attestation, produced by a specific field-programmable gate array die, that (a) the die is a specific one from a specific vendor batch (device DNA) and (b) the die is currently running a specific bitstream (bitstream attestation), optionally strengthened by a Physical Unclonable Function (PUF) layer. The construction reuses well-known primitives from the FPGA-security literature ([SACHa DATE 2019](https://ieeexplore.ieee.org/document/8715217), [PUFatt DAC 2014](https://dl.acm.org/doi/10.1145/2593069.2593192), [Guajardo et al.

The novelty is the **packaging** of these primitives as a discrete DePIN primitive with a specific revenue model and a specific mesh-integration story. + +## 1. Motivation + +DePIN networks (Helium, Pollen, World Mobile, Filecoin, Akash, Bittensor) rely on operators contributing physical infrastructure — radios, storage, compute. Payment for that work depends on proving the operator actually did the work. Existing solutions choose one of three anchors: + +- **Identity-only** ([Helium Proof-of-Coverage](http://whitepaper.helium.com)): operator has a chip that signs identity messages (ECC608, HIP-19). Chip attests *who* did the work, not *what* was done. Works for coverage. Weak for compute. +- **Software-only** ([Bittensor Yuma Consensus](https://bittensor.com)): operators run a validated model; consensus among validators substitutes for hardware proof. Vulnerable to Sybil at scale and to collusion. +- **Cloud TEE** (AWS Nitro, Intel SGX, ARM TrustZone): trusted execution environments give strong attestation but require trust in the silicon vendor and are unavailable on open FPGA hardware. + +Proof of FPGA fills a gap: **strong hardware-anchored attestation on open FPGA hardware**, suitable for compute and coverage workloads that reject cloud-TEE lock-in. + +## 2. Threat model + +Adversaries we defend against: + +- **T1 — Software replay.** Attacker replays a captured attestation from a legitimate device. Defended by nonce/timestamp binding in every attestation. +- **T2 — Bitstream swap.** Attacker programs a modified bitstream (e.g., that fakes work) and expects to still be rewarded. Defended by bitstream-hash attestation (§4.2). +- **T3 — Device impersonation.** Attacker claims another operator's rewards by copying flash contents. Defended by device DNA (§4.1) and, when available, PUF (§4.3). + +Adversaries we explicitly do NOT defend against: + +- **T4 — Silicon-vendor backdoor.** If the FPGA vendor has hidden test modes that leak DNA or accept spoofed bitstream hashes, Proof of FPGA fails. This is a fundamental limit of any hardware-rooted attestation. Mitigation is vendor diversity (multiple die families in the network). +- **T5 — Physical extraction.** Attacker delaminates the die and reads the DNA and PUF secrets electrophysically. Cost is high; Proof of FPGA raises the bar but does not eliminate this. +- **T6 — Side-channel attacks.** Power analysis of a running attestation could leak PUF challenge responses. Constant-time implementation is out of scope for v0. + +## 3. Non-claims + +We say these out loud so they cannot be mistaken for our claims: + +- We do NOT invent PUF. See [Guajardo et al. CHES 2007](https://link.springer.com/chapter/10.1007/978-3-540-74735-2_5) for the SRAM-startup PUF construction, and [PUFatt DAC 2014](https://dl.acm.org/doi/10.1145/2593069.2593192) for processor-based PUFs. +- We do NOT invent bitstream attestation. See [SACHa DATE 2019](https://ieeexplore.ieee.org/document/8715217) for the strongest primitive we build on: an FPGA proving to a verifier that a specific bitstream is loaded without a trusted third party. +- We do NOT invent PQC-signed FPGA attestations. See [Papalamprou et al. arXiv:2506.21073](https://arxiv.org/abs/2506.21073) for a recent construction that binds signatures to blockchain. +- We do NOT claim FPGA proof replaces silicon-level attestation for all threat models. It complements silicon and is open-hardware-friendly. + +## 4. Construction + +### 4.1 Device DNA (A2 stage) + +Every 7-series Xilinx die exposes a 57-bit device DNA via the `DNA_PORT` primitive ([UG768 §Device DNA](https://docs.amd.com/v/u/en-US/ug768_7Series_XADC_XilinxWiki), [XAPP1082](https://docs.amd.com/v/u/en-US/xapp1082-secure-boot)). UltraScale dies use a 96-bit DNA via `DNA_PORTE2`. Equivalent primitives exist on Efinix (Trion), Lattice (ECP5), Achronix. + +Our A2 implementation lives in `fpga/attest/dna_reader.v`. On reset the module pulses `READ`, then shifts 57 bits out on `DOUT` MSB-first, and latches the value in `dna_out` guarded by a `valid` strobe. Simulation goes through iverilog + a behavioural stand-in (`sim/dna_port_model.v`); synthesis goes through openXC7 + yosys `synth_xilinx -family xc7` (with a `(* blackbox *)` DNA_PORT stub gated by the `SYNTHESIS` define, W4). + +**Attestation payload for A2**: `H(nonce ‖ device_dna)` signed by a hardware-anchored key derived from device_dna (§4.4). Verifier holds the public key of the operator; a MITM cannot replay one device's response as another because `device_dna` differs. + +### 4.2 Bitstream attestation (A3 stage) + +We hash the loaded bitstream with SHA-3 and sign the hash with the A2 key. The verifier holds the "golden hash" of the sanctioned bitstream and checks: (a) the signature verifies under the operator's public key, (b) the hash matches the golden hash, (c) the nonce is fresh. + +The primitive is [SACHa (DATE 2019)](https://ieeexplore.ieee.org/document/8715217). Our contribution is not the primitive — it is the integration path: the same signing key that A2 uses, the same nonce discipline, and delivery over the mesh transport (see §5). + +**Gate for A3**: swap in a modified bitstream, verifier must reject. Original bitstream verifies. Replay of yesterday's attestation is rejected (nonce/timestamp binding). + +### 4.3 PUF layer (A4 stage) + +A PUF (Physical Unclonable Function) uses manufacturing variations in the die — e.g., which SRAM cells power up to 0 vs 1, or which of two ring-oscillators is faster — to derive a per-die secret that cannot be reproduced by cloning. On 7-series and UltraScale we use SRAM-startup PUF ([Guajardo et al. CHES 2007](https://link.springer.com/chapter/10.1007/978-3-540-74735-2_5)); on families without accessible startup SRAM we use ring-oscillator PUFs. + +Target metrics (all `-sim` until measured on real silicon per the A1-A4 ratchet): + +- Intra-device Hamming distance < 5% (stable across temperature and voltage). +- Inter-device Hamming distance > 45% (near-ideal 50%). + +The PUF response is folded into the A2 key derivation (§4.4) so that an attacker who extracts flash and key store still cannot reproduce the identity without the die itself. + +### 4.4 Key derivation + +``` +identity_key = KDF(device_dna ‖ puf_response ‖ die_family_id) +``` + +where KDF is any accepted key derivation function (HKDF-SHA-256 in the v0 reference). The identity key is used to sign both A2 and A3 attestations. The KDF binding to `die_family_id` is a defence-in-depth measure against cross-family key confusion. + +## 5. Mesh integration + +Attestations are transported over the Tri-Net mesh (`trios_meshd`) inside the same envelope that carries other overlay traffic. For confidentiality and integrity, we wrap the attestation in the crypto envelope specified in `specs/audio_crypto.t27` (W3, 2026-07-14 — currently uses `-crypto-placeholder` primitives; audited replacement pending). This gives: + +- **Confidentiality**: passive observers cannot correlate attestations to physical devices. +- **Integrity**: bit-flips in transit are rejected by the MAC. +- **Replay resistance**: nonce freshness enforced by the envelope's counter. + +## 6. Monetization + +Concrete revenue paths, cited in `tri-net-fpga-attestation-workflow` skill §Monetization Vectors: + +1. **DePIN hardware proof as a service** — SDK that lets other DePIN projects plug in "this attested FPGA ran this workload". Per-verification metering or per-node license. +2. **TEE-alternative for mesh routing** — sold to sovereignty-focused telecom, defence-adjacent civilian, high-assurance IoT — buyers who reject Intel SGX / ARM TrustZone lock-in. +3. **Audit-as-a-service** — periodic attestation sweeps of a customer's deployed fleet: "prove no board has been swapped or reflashed since deployment". +4. **Tri-Net internal use** — every node ships with Proof of FPGA baked in; premium tier for enterprise / defence buyers. +5. **Standards / consortium play** — anchor a DePIN attestation standard; revenue from certification services. + +## 7. Ratchet discipline + +Every Proof of FPGA claim must survive the four-stage ratchet documented in `tri-net-fpga-attestation-workflow` skill: + +1. **Sim (Verilator / cocotb)** — all edge cases pass in code. +2. **Synth (Vivado / Efinix / Lattice)** — place-and-route completes without timing violations. +3. **Single-device smoke** — device DNA reads, PUF stable across ≥10 power cycles, bitstream hash signs and verifies. +4. **Cross-device smoke** — attestations from board-A rejected as replay on board-B. + +Skip any stage — the primitive is `-sim` until the missing stage passes. This mirrors the discipline of `tri-net-m2-m4-workflow` §Sandbox-vs-hardware. + +Silicon-freeze date for Tri-Net's SKY26b tape-out is **2026-10-01** (78 days from this document). Any primitive not through A1–A4 by that date ships FPGA-only until the next silicon spin. + +## 8.

Ratchets 3/4 and 4/4 pending hardware access. +- **A3 Bitstream attestation**: not started. Planned as A3 workstream in a future wave. +- **A4 PUF layer**: not started. +- **A5 Whitepaper**: THIS DOCUMENT (v0). + +Nothing in §4-§5 has been measured on a Tri-Net node in the field.

What v0 does not cover + +- Formal security proofs of the KDF binding. +- Constant-time implementation guidance. +- Hardware-specific side-channel mitigation. +- Comparative benchmarks vs Intel SGX / AWS Nitro (requires the SKY26b tape-out to be back from fab). +- Cross-family attestation composition (e.g., a Tri-Net node with both a Zynq-7020 and an Efinix Trion on the same PCB). + +These land in whitepaper v1 after A2–A4 ratchets are GREEN on hardware. + +## 10.

Supersedes hand-written logic in src/bin/mdns_proxy.rs (codegen deferred: t27c absent in this env). - docs/T27_ENFORCEMENT.md: enforcement model + measured toolchain findings (t27c absent; crate pre-broken on main; audio_crypto fail-closed by non-link). - docs/ITERATION_LOG.md: W7 part-4 measured facts; translate the one Cyrillic header line to English (docs are English-only per CLAUDE.md). Sandbox-measured: lefthook 7/7 negative blocked + 4/4 positive pass; gen-provenance OK over 75 gen files; mdns_proxy 13/13 and audio_crypto 17/17 unit (rustc --test, isolated) x3 deterministic, clippy clean. Whole-crate cargo build FAILS (106 errors) due to pre-existing invalid t27c codegen on main (not a PR regression).

the let-mut split bug is fixed, dropping whole-crate build errors 106 -> 28. Migrate src/bin/mdns_proxy.rs to source all spec-verifiable logic from generated gen/rust/mdns_proxy.rs via #[path]; add smoke/mdns_proxy_smoke.sh (two-process, N=5, 5/5 x3 deterministic; 14/14 unit). Fix one genuine spec typo in multipath_routing.t27 through the pipeline + add its anchor. Eliminate the audio_crypto placeholder by regeneration (no allowlist quarantine needed). Harden two Lefthook gates (no-gen-edits ties staged gen byte-for-byte to fresh t27c output; golden-anchor exempts gen/ via banner provenance) so the pipeline's own output cannot fail the pipeline's rules. Remaining blockers isolated, NOT masked: t27c defect A ([u32;N] param -> Vec<>, 26 E0107) and defect B (compare/logical-not not lowered to u32, 2 E0308); both block whole-crate build, neither hand-patched. phi^2 + phi^-2 = 3 | TRINITY Co-Authored-By: Claude Opus 4.7 --- .t27-allowlist | 21 +- docs/ITERATION_LOG.md | 24 ++ docs/T27_ENFORCEMENT.md | 102 ++++---- gen/rust/access_control.rs | 32 +-- gen/rust/adaptive_retry.rs | 8 +- gen/rust/adaptive_routing.rs | 44 ++-- gen/rust/anomaly_detector.rs | 141 ++++------ gen/rust/api_documenter.rs | 148 ++++------- gen/rust/area_optimization.rs | 2 +- gen/rust/audio_crypto.rs | 411 ++---------------------------- gen/rust/auto_config.rs | 165 ++++-------- gen/rust/bandwidth_allocator.rs | 90 +++---- gen/rust/cache_management.rs | 147 ++++------- gen/rust/compression_engine.rs | 112 +++----- gen/rust/congestion_control.rs | 89 +++---- gen/rust/cross_layer_optimizer.rs | 60 ++--- gen/rust/docs_generator.rs | 75 ++---- gen/rust/energy_aware_routing.rs | 91 +++---- gen/rust/failure_predictor.rs | 73 +++--- gen/rust/fault_detection.rs | 72 ++---- gen/rust/flow_control.rs | 119 +++------ gen/rust/frame_buffer.rs | 8 +- gen/rust/health_dashboard.rs | 96 +++---- gen/rust/health_monitoring.rs | 50 ++-- gen/rust/hello.rs | 10 +- gen/rust/integration_framework.rs | 186 +++++--------- gen/rust/integration_tests.rs | 4 +- gen/rust/key_management.rs | 69 +++-- gen/rust/link_quality_monitor.rs | 28 +- gen/rust/link_statistics.rs | 4 +- gen/rust/lite_crypto.rs | 25 +- gen/rust/load_predictor.rs | 130 ++++------ gen/rust/local_processing.rs | 120 +++------ gen/rust/m3_multihop.rs | 42 +-- gen/rust/mdns_proxy.rs | 141 ++++++++++ gen/rust/mesh_node_sim.rs | 4 +- gen/rust/mesh_protocol_stack.rs | 8 +- gen/rust/multipath_router.rs | 36 +-- gen/rust/multipath_routing.rs | 2 +- gen/rust/network_analytics.rs | 48 ++-- gen/rust/network_coding.rs | 48 ++-- gen/rust/network_metrics.rs | 2 +- gen/rust/network_orchestrator.rs | 91 +++---- gen/rust/network_simulator.rs | 108 +++----- gen/rust/olsr_routing.rs | 12 +- gen/rust/packet_loss_injection.rs | 2 +- gen/rust/packet_queue.rs | 2 +- gen/rust/pattern_predictor.rs | 62 ++--- gen/rust/performance_profiler.rs | 106 +++----- gen/rust/power_monitoring.rs | 55 ++-- gen/rust/production_scenarios.rs | 4 +- gen/rust/quarantine_manager.rs | 99 +++---- gen/rust/redundancy_management.rs | 61 ++--- gen/rust/resource_scheduler.rs | 155 ++++------- gen/rust/self_healing.rs | 55 ++-- gen/rust/swarm_coordinator.rs | 35 +-- gen/rust/test_framework.rs | 106 +++----- gen/rust/test_validator.rs | 66 ++--- gen/rust/topology_visualizer.rs | 196 +++++--------- gen/rust/traffic_animator.rs | 172 ++++--------- gen/rust/transport_tx_fsm.rs | 16 +- gen/rust/trust_manager.rs | 14 +- gen/rust/wire.rs | 10 +- lefthook.yml | 60 ++++- smoke/mdns_proxy_smoke.sh | 65 +++++ specs/multipath_routing.t27 | 4 +- src/bin/mdns_proxy.rs | 293 +++++++++++---------- 67 files changed, 1870 insertions(+), 3066 deletions(-) create mode 100644 gen/rust/mdns_proxy.rs create mode 100755 smoke/mdns_proxy_smoke.sh diff --git a/.t27-allowlist b/.t27-allowlist index fee8cae3..4162658a 100644 --- a/.t27-allowlist +++ b/.t27-allowlist @@ -49,14 +49,13 @@ src/bin/mdns_proxy.rs # RFC 8766 discovery-proxy runtime; envelope logic t build.rs # cargo build script: mtime-driven t27c regen shim # --------------------------------------------------------------------------- -# CATEGORY D -- QUARANTINED PLACEHOLDER (NOT production, NOT audited). -# gen/rust/audio_crypto.rs was hand-authored as a "skeleton" (its header is -# NOT the canonical t27c banner) and carries XOR-keystream + truncated-SHA256 -# MAC primitives that are NOT in specs/audio_crypto.t27.

Status: DECISION COMPLETE - HARDWARE UNVERIFIED (architecture closed; real-device validation is a separate gate, not a reason to stay draft). Factual corrections (authoritative-source checked): - Board naming normalized to P201 Mini (P203 stated once as deprecated alias). - Variant A (USB Personal Hotspot via ipheth) kept PROVISIONAL PRIMARY, gated on a real-device acceptance gate (Apple 111785 + ArchWiki tethering). - Removed false "Airplane Mode + Wi-Fi off => hotspot without SIM" claim; Personal Hotspot shares cellular (Apple iph45447ca6). MDM/MVNO restriction elevated to primary risk. - Removed false "NSLocalNetworkUsageDescription gives Safari PWA an mDNS-browse prompt" claim; iOS Safari has no public DNS-SD browse API (Apple NetServices FAQ + DTS 704037). Lane A uses deterministic entry (QR / URL / stable trinet-admin.local); Avahi advert preserved for native tooling only. - Removed uncited goodput numbers and "all iPhones" universals. - Self-signed https:// does not satisfy Safari trust; curl -k is not browser evidence; certificate/pairing/bootstrap deferred to E2.2. Smoke is now two-level: Level 1 sandbox IP/API sim (smoke/e1_1_admin_httpd_smoke.sh, measured PASS) and Level 2 real-device gate (doc section 7, blocking, hardware).

The iPhone is +the DHCP server (typically `172.20.10.1/28`); the P201 Mini is the client. -**Плюсы:** -- Работает на всех iPhone начиная с iOS 3 (Personal Hotspot появился давно, USB path стабилен). -- Все Yocto/PetaLinux сборки для Zynq имеют kernel option `CONFIG_USB_IPHETH` — включаемо. -- Пользователь просто нажимает «Personal Hotspot» в Settings. -- Zero apple-side coding — iPhone делает host duty. +**How it works on Linux:** +The `usbmuxd` + `libimobiledevice` stack plus the kernel `ipheth` driver +presents the iPhone as a USB Ethernet interface; a DHCP client on the Linux +side obtains a lease. The ArchWiki +[iPhone tethering](https://wiki.archlinux.org/title/IPhone_tethering) page +documents the full flow (`usbmuxd`, the on-device Trust prompt, `ipheth`, DHCP). +Apple documents USB Personal Hotspot and the Trust flow at +[support.apple.com/en-us/111785](https://support.apple.com/en-us/111785). -**Минусы:** -- iPhone получает **приоритет DHCP** — узел P203 виден как «internet client», а не наоборот. Admin PWA на iPhone должна обращаться к узлу по DHCP-assigned адресу узла (172.20.10.2/3/…), который iPhone контролирует. -- Требует USB-C-to-Lightning или USB-C-to-USB-C кабель (iPhone 15+ имеет USB-C). -- Personal Hotspot требует активной SIM карты в некоторых операторов (не везде — MVNO часто блокируют hotspot). Обход: включить в Airplane mode + Wi-Fi off, тогда tether работает без cell. -- **iOS 14+ NSLocalNetworkUsageDescription:** iPhone Safari разрешает mDNS-browse только с explicit purpose-string prompt. См. [Apple Local Network Privacy FAQ](https://developer.apple.com/forums/thread/663858). +**Pros:** +- Apple-supported, documented USB path; no Apple-side code required. +- Zynq Yocto/PetaLinux kernels can enable `CONFIG_USB_IPHETH`. +- User action is a single tap ("Personal Hotspot") plus the Trust prompt. -**Compatibility:** iPhone 12 и новее ✅ (все имеют Personal Hotspot).

Не документировано Apple, работает эмпирически. +**Cons:** requires a custom `usbmuxd` build (not mainline); undocumented by +Apple and may break on any iOS release; iOS does not reliably start a DHCP +client for USB Ethernet outside Personal Hotspot mode; requires PetaLinux +rootfs changes. -**Плюсы:** -- P203 контролирует IP-план: iPhone получает адрес из mesh-плана (например 10.42.0.5/24), напрямую маршрутизируется в TUN interface `trios_meshd`. -- Не требует iPhone Personal Hotspot (не потребляет cellular data). +**Verdict: FALLBACK.** Not for v0.1.

Apple's Bonjour +[NetServices FAQ](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/NetServices/Articles/faq.html) +describes native DNS-SD / link-local behavior, and Apple DTS confirms in +[forum thread 704037](https://developer.apple.com/forums/thread/704037) that iOS +Safari does not expose a Bonjour service-list UI to web content. + +Therefore, for Lane A the PWA reaches the node through a **deterministic entry +path**, in priority order: + +1. **QR code / printed URL** carrying the node's admin URL (numeric IP for the + iPhone-assigned subnet, e.g. `https://172.20.10.2:8443`). +2. A **stable `trinet-admin.local` hostname**, used only **after** name + resolution to the node is proven on the real device (mDNS `.local` + resolution of a single known name by the OS resolver - distinct from + service browsing). + +**Avahi advertisement of `_trinet-admin._tcp.local` is preserved** on the node +for native tooling and future clients (Bonjour-capable native apps, `dns-sd`, +`avahi-browse`).
