… still blocked
QAIRT 2.43 (latest from Qualcomm Developer Network) ships QnnSystem 1.7.0.
ai-edge-litert 2.1.4 requires QnnSystem >= 1.8.0 in qnn_manager.cc:284.
Gap closed from 2 versions (D-024) to 1 — but still blocking.
Net change vs yesterday's QAIRT 2.41 sweep:
D-024 (QnnSystem version drift): half-resolved (1.6 -> 1.7; needs 1.8)
D-025 (TFLite EMBEDDING_LOOKUP): RESOLVED — 2.43 frontend handles tied embed
D-027 (TFLite tied-embed): RESOLVED — same
D-026 (ONNX 1.21 incompat): not exercised (path C deferred)
What this proves about the model:
qwen_frozen_subgraph (Qwen2.5-1.5B layers 1..26 — the ELO frozen middle)
TFLite-converts cleanly at 4.6 GB. Architecture is supported. Block is
purely the Qualcomm SDK runtime version check.
Two queueable next moves (see D-029):
1. operator: scp QAIRT 2.44+ when it ships -> rerun same sweep, ~30 min
2. agent: clean pod (no GPU-sharing sibling), retry ai-edge-litert==2.0.3
(might accept QnnSystem 1.7 -> immediate unblock)
Until then: registry stays locked (litert_qnn_sm8750.confirmed_for_socs=()),
test_qnn_backend_is_locked_until_proof continues to pass, Gate B (Vulkan via
dm3 fork-and-own from D-027 above) remains the recommended hedge.

…try promoted Perplexity-search response identified the exact pairing: LiteRT 2.1.4's third_party/qairt/workspace.bzl pins qairt/2.44.0.260225 (commit-tagged in google-ai-edge/LiteRT). The bundled libLiteRtCompilerPlugin_Qualcomm.so is compiled against QAIRT 2.44 headers, expects QnnSystem 1.8.0. QAIRT 2.43 ships QnnSystem 1.7.0 -> mismatch. QAIRT 2.44 ships QnnSystem 1.8.0 -> matching pair.

D-031 reinforces D-030's registry promotion with ON-DEVICE evidence — the
Phase 0G AOT compile artifacts actually execute on the operator's physical
phone, not just on the AI Hub Workbench / pod simulator.
Path proven (alternative to absent aarch64-android LiteRT runtime, D-019):
HOST : extract embedded QNN context binary from apply_plugin .tflite
via scripts/host/extract_qnn_context.py
(DISPATCH_OP custom_options flexbuffer carries
bytecode_offset / bytecode_size / name=qnn_partition_0;
the QNN binary is appended verbatim to the tflite at offset)
PHONE : adb push <scope>.qnn.bin /data/local/tmp/phase1a/
qnn-net-run --retrieve_context <scope>.qnn.bin
--backend libQnnHtp.so
On-device verdicts (REDMAGIC NX789J / SM8750 / Hexagon NPU):
qwen_block (1 layer, 90 MB binary):
10x wall-clock: 0.523 s
output FP32 stats: min=-3.38 max=3.50 mean~0 std=1.14
-> plausible single-layer transformer state
qwen_frozen_subgraph (Qwen2.5-1.5B layers 1..26 = the actual ELO frozen middle,
2.3 GB binary):
10x wall-clock: 10.62 s (dominated by mmap setup of 2.3 GB on first run)
output FP32 stats: min=-20.4 max=21.6 mean=0.22 std=6.15
-> plausible 26-layer cascade (std grows with depth, mean stays near zero,
all values finite, all 24576 outputs nonzero)
The output statistics are the strongest evidence of physical correctness.
A stack of 26 random-init Qwen layers acting on a zero input produces hidden
states with growing variance through depth and near-zero mean — exactly what
we observe. This rules out 'binary loaded but produced garbage' and 'binary
loaded but ran on CPU fallback' (the latter is also ruled out by the wall-clock
being implausibly fast for 26 layer-passes on Oryon CPU; ~1 s/inf on Hexagon
is plausible, ~4 min/inf on CPU would be the alternative).
qnn-platform-validator pre-flight on device confirms:
Backend GPU (Adreno 830) : Hardware Supported, Libraries Found
Backend DSP (Hexagon NPU) : Hardware Supported, Libraries Found

Phase 1A on-device verdict pushed in commit 24355da. qwen_frozen_subgraph (Qwen2.5-1.5B layers 1..26 = the actual ELO frozen middle) executes end-to-end on REDMAGIC SM8750 / Hexagon NPU in ~1.06s/inf wall-clock (10 inferences in 10.62 s including 2.3 GB mmap setup). Output FP32 statistics (min=-20.4, max=21.6, mean=0.22, std=6.15) match expected 26-layer transformer cascade. See D-031 + runtime/reports/phase1a/2026-05-02T0440Z/. Phase 1A is OPEN. |
Adds zero-coder overnight execution:
scripts/phone/overnight_inference.sh - inference loop with hash-chained
audit JSONL + curl-based HF heartbeat
docs/PHONE-OVERNIGHT-RUNBOOK.md - operator-facing instructions
Loop characteristics:
- Each iter runs 100x qwen_block (1-2 s) or 10x qwen_frozen_subgraph
(10 s) on Hexagon NPU via qnn-net-run --retrieve_context.
- Telemetry per iter: battery (level/temp/AC), all CPU/skin/battery
thermal zones, memory headroom, disk free, per-inference timing,
output sanity bytes (first 32 bytes of FP32 result).
- Hash-chained audit JSONL on /sdcard/Polymath/phase1a/audit.jsonl
(sdcard so survives ADB disconnect; sha256 prev_event_hash chain).
- HF dataset push every 10 iters via curl + base64 + commit API:
Architect-Prime/polymath-telemetry/phase1a/<run_id>/audit.jsonl
Operator monitors live in any browser. No reconnection needed.
Auto-stop conditions (graceful, all log a final event):
- /sdcard/Polymath/phase1a/STOP file (operator kill switch)
- battery temp > 45.0 C (thermal_halt)
- battery level < 15% (low_battery_halt)
- missing required QNN binary (fatal_missing_artifact)
Detachment proven: nohup setsid + svc power stayon ac means
the loop's PPID is 1 (init) the moment it starts. ADB disconnect,
USB unplug, screen off — none kill the loop.
Smoke test verified end-to-end:
- 11 audit rows, all rc=0 + out_size=98304 (= 1x16x1536 FP32)
- per_inf_ms: 13-18 ms for qwen_block (steady-state)
- HF push at iter=10: HTTP 200 OK, commit 963cb6fa
- Graceful stop on /sdcard/Polymath/phase1a/STOP touch verified
- Process tree shows PPID=1 confirming detachment
Two implementation gotchas fixed during smoke test:
- Android xxd -p wraps lines at column 60; tr -d '\n\r ' makes
the hex output a single token (was splitting JSON rows)
- qnn-net-run resolves input_list paths relative to cwd; runner
now cd's to /data/local/tmp/phase1a before invoking

docs/REPORT-2026-05-02-phase-0-1a-progress.md is a self-contained external-audience writeup of the past 72 hours: - Executive summary with the key numbers (5/5 AOT compiles ok, on-device wall-clock, output FP32 sanity stats) - Project boundary (verbatim from polymath_ai/boundary/text.py) - Why this matters (edge-LLM training vs inference distinction; SM8750 as the first widely-available SoC where this is tractable) - Methodology in one paragraph (falsifier registry + boundary scanner + hash-chained audit + decision log) - Roadmap status table (Phase 0A through 2C, with closure dates) - Phase 0G deep-dive (the QAIRT 2.41 -> 2.43 -> 2.44 progression; the matching-pair finding from LiteRT's workspace.bzl; the public-CDN URL discovery; the 5/5 verdict) - Phase 1A deep-dive (the apply_plugin tflite -> embedded QNN binary extraction; the qnn-net-run --retrieve_context path; the ruling-out of CPU-fallback by wall-clock implausibility + numerical sanity) - Overnight chain (PPID=1 detachment; svc power stayon ac; curl + base64 + HF datasets commit API) - Phase 1A.A scoping (real-data ELO Stage-1 plan) - Phase 1B / 1C / 2A / 2B / 2C roadmap - Notes for OEM phone-platform engineers (matching-pair pattern, extract-and-run pattern, no-NDK deployment story, thermal envelope observations, open-tooling licensing) - Honest scope of what is NOT yet proven - References (PR #4, decision log, scripts, HF datasets) Confirmed live: while writing this commit, the overnight loop on the operator's REDMAGIC continued pushing HF heartbeats every ~2 min after the USB cable was disconnected from the host.

docs/REPORT-2026-05-02-comprehensive.md is the long-form companion to
docs/REPORT-2026-05-02-phase-0-1a-progress.md. The shorter report assumed
ML/edge-ML background; this one onboards from zero context.
Structure (17 sections, table of contents at the top):
1. Cover (project name, custodian, repo, license posture)
2. Executive summary (one-page TL;DR with all headline numbers)
3. What this project is, in plain language (no jargon)
4. Project boundary (verbatim self-imposed-scope block)
5. The thesis: why now (3 reasons the 2026 hardware/SDK/training-scheme
stack is the inflection point)
6. Technique: ELO continual pretraining
(frozen-middle layout, tied-embedding subtlety, frozen-param hashing)
7. Hardware: SM8750 + REDMAGIC 10 Pro+
(active fan, charge bypass, Game Zone, why this specific handset)
8. Software stack (Qwen, SmolLM3, ai-edge-litert, QAIRT, our substrate)
9. Methodology (falsifier-driven, boundary-anchored, audit-chained,
RESISTANCE patterns named)
10. Roadmap with what each phase actually means
11. Engineering done so far — every blocker named with its decision row
(D-001 untie, D-013 Mac SDK, D-018 Termux torch, D-019 no
aarch64-android wheel, D-021 Apple Silicon apply_plugin_main missing,
D-022/023 libQnnSystem.so absent, D-024 QnnSystem 1.6 vs 1.8,
D-025/D-027 EMBEDDING_LOOKUP, D-026 ONNX 1.21 incompat,
D-029 QAIRT 2.43 still mismatch, D-030 the unblock, D-031 on-device)
12. Data we have actually observed
- ELO smoke loss: 14.78 -> 8.76 across 3 steps, frozen invariant held
- Tokenizer fertility: zu/el flagged, 12-language mix revised
- Phase 0G: 5/5 ok, sizes 140KB/179MB/4.6GB/299MB/2.4GB tflite ->
166KB/90MB/2.3GB/150MB/960MB QNN binaries
- Phase 1A: 11-18 ms/inference; FP32 std grows 1.14 -> 6.15 over 26 layers
- Phase 1A.0 overnight: 32 C battery, 85% level, AC charging,
per_inf_ms convergent, HF push every ~2 min
13. Current state (live, with PID/PPID/run_id/iter)
14. Phase 1A.A and beyond — concrete scoping for each upcoming phase
including the Phase 3A distributed-Polymath research direction
15. Why this matters externally
(separate paragraphs for ML engineers / on-device practitioners / OEMs)
16. Known limitations (no overclaim — what we have NOT yet proven)
17. References + glossary (40+ terms) + license summary
Glossary covers all jargon used in either report; reader needs no
external lookup to follow the technical narrative.

…unplugged
Issues with v1 in actual fridge deployment:
- HF push broke past iter ~530: Android argv limit hit by printf with
base64-encoded 300+ KB audit body, plus HF inline-payload validation
rejecting the size with HTTP 400 'specify lfsFile'
- Sustained NPU load on the 10-second sleep cadence drew more current
than the operator's USB-PD adapter could supply, causing battery to
drain ~10.5%/hour even with AC connected. The cable was a tether for
no benefit; phone needed to go fridge-unplugged anyway.
v2 changes (only two lines materially):
HF_PUSH_EVERY: 10 -> 0 # disable HF push (broken; saves Wi-Fi power)
SLEEP_SECS: 10 -> 60 # ~6x lower duty cycle, ~2x lower avg draw
Audit log stays on /sdcard, adb-pulled in the morning. All other
telemetry, hash-chaining, auto-stop conditions identical to v1.
Smoke-test on phone right after start: PID detached (PPid=1, init-adopted),
iter 1 logged with rc=0 and out_size=98304 (correct 1x16x1536 FP32).
Battery 72%, temp 24 C (out of fridge during transition).
Operator next steps:
1. Top up to 90%+ on a wall charger (NOT laptop USB; needs 20W+)
2. Unplug; phone goes in fridge
3. Loop self-runs through power-source change without restart
Estimated runtime from 90% -> auto-halt at 15%: ~8-10 hours.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
D-032 documents the full Phase 1A.0 (overnight chain) + 1A.B (steady-state
benchmark) closeout. The fridge-mode plan turned into a worst-case ambient
test (the operator could not put the phone in cold storage), which became
the stronger experiment.
Verified numbers from runtime/reports/phase1a/2026-05-02T1802Z-overnight-v2/:
Wall-clock: 6 h 15 m
Batches: 251 (226 qwen_block + 25 qwen_frozen_subgraph)
Inferences: 22,850 total (22,600 + 250)
Success rate: 251/251 = 100% (every batch rc=0, out_size=98304)
Halt cause: operator-initiated stop_signal_received
Per-inference latency, steady state on Hexagon NPU:
qwen_block (1 Qwen2.5-1.5B layer):
n=226, p50=19 ms, p95=22 ms, max=25 ms, mean=16.8 ms
qwen_frozen_subgraph (Qwen2.5-1.5B layers 1..26 = ELO frozen middle):
n=25, p50=576 ms, p95=811 ms, max=817 ms, mean=600.4 ms
The 576 ms/inference for the full ELO frozen middle is the locked-in
Phase 1A baseline. INT8 quantization (Phase 2A) targets a 3-4x reduction.
Battery + thermal:
Battery: 72% start -> 85% peak (charged) -> 73% end (essentially flat)
Battery temp: peaked at 32 C (room ambient)
CPU0 temp: 58 C startup -> 28-36 C steady state
AC powered: plugged in initially; operator unplugged ~iter 120-252;
unplugged drain rate observed: 3.2 %/hour
Extrapolated unplugged battery life: ~25 hours
This INVALIDATES the projection in PHONE-OVERNIGHT-RUNBOOK.md that
estimated 7-10 %/hour drain. Actual is much better. Fridge cooling is
NOT required for this duty cycle; room ambient is sufficient.
Falsifier outcomes (D-032):
silent_output_corruption_under_load -> pass (zero corruption events)
thermal_throttling_under_sustained_load -> pass (peaked 32 C)
battery_drain_exceeds_safe_envelope -> pass (~3.2 %/h vs 10%/h projected)

Verdict
Phase 0G AOT compile is UNBLOCKED. All 5 scopes returned
okwith real Qualcomm SM8750 .bin context binaries. Registry promoted:litert_qnn_sm8750.confirmed_for_socs = (("SM8750", 1.0),). Phase 1A QNN routing is cleared.What unblocked it
The Perplexity-search response identified the exact SDK pairing: LiteRT 2.1.4's
