+# HydraPulse development contract
+
+Work within `field/HydraPulse` and the additive `.github/workflows/hydrapulse.yml`.
+Read parent repository instructions before changing this subtree. Do not modify sibling
+examples, the root dependency gitlinks, root license, or the old HydraPulse repository
+as a side effect. Use the existing root dependency at `../../libDaisy`, verified
+against `deps.lock.json`. Qualification must run in an isolated clean checkout;
+never force-rebuild a shared user's dependency tree with different compiler flags.
+
+The firmware audio callback is the only writer of Engine, Controller and sampled control
+state. Foreground MIDI sends fixed-size messages through SPSC queues; foreground display
+and logs consume snapshots. Never introduce logging, display/I2C transfers, file I/O,
+heap allocation, mutex waits or unbounded queue drains into the callback.
+
+Keep 16 step keys and Tune / Decay / Character / Level. Changes to input gestures must
+update Controller tests, the manual, control map and Mermaid sources in the same change.
+Keep the two images separate: Field Truth is permanent diagnostics; Beat is an instrument
+candidate. Neither host tests nor an ARM build can close the physical P0 gate.
+
+Run the local CMake/CTest suite, Python tests, offline repository validator, preset
+generation check and deterministic host render comparison. Run a real ARM build through
+`tools/build_target.py` before calling an image build-verified. The adapter stub is only a
+syntax/ownership aid; never package it as firmware. Preserve failures and NOT_RUN states.
+
+No automatic hardware flashing, force push, global dependency update, commercial manual
+redistribution or invented hardware evidence. A `.dvpe` project requires a real schema,
+known block IDs, import/export roundtrip and generated-code tests; otherwise omit it.
+
+The user has authorized a normal non-destructive integration into Denys/DaisyExamples.
+Use the repository's existing branch/PR policy, compare every destination file, test the
+actual merged tree, and report exact commits and CI runs. Ask only for material conflicts,
+destructive replacement, credential actions, public-release licensing, or physical flashing.

+# HydraPulse Field | 0.2.0 candidate
+
+A direct, four-voice synthesized drum machine for stock Electro-Smith Daisy Field.
+**Select a drum → tap 16 steps → edit the sound → Play.**
+
+This subtree is designed for `Denys/DaisyExamples/field/HydraPulse`. It is an additive
+development candidate, not a hardware-qualified release. The original 29-file R0 package
+is preserved without changes under `references/r0`; the old dedicated repository is not deleted.
+
+## What is implemented
+
+Two separate firmware sources share a host-testable foundation:
+
+| Image | Purpose | Source |
+|---|---|---|
+| HydraPulseTruth | Stereo passthrough, raw key events, knobs/CV/Gate/MIDI telemetry, momentary output tests, OLED/LED diagnostics and callback instrumentation | `firmware/FieldTruth.cpp` |
+| HydraPulseBeat | Hammer kick, Crack snare, Steel metallic hat, Arc phase-modulated percussion; 16-step A/B/Fill banks, accents, mutes, swing, drive, soft pickup, stop/panic and eight original tutorials | `firmware/HydraPulse.cpp` |
+
+One Home screen and a momentary Shift palette replace a nested menu tree. All state
+changes that affect sound are owned by the audio callback. Display and telemetry are
+foreground-only. The DSP uses original bounded algorithms and no DaisySP runtime dependency.
+
+Key and switch LEDs provide feedback in the instrument. Knob LEDs are not implemented
+and remain dark in both images; this does not indicate a knob input fault.
+
+Current integration evidence is recorded in [the integration log](docs/INTEGRATION_2026-09-08.md).
+The supplied package's historical results remain in [candidate validation](docs/VALIDATION.md).
+A software or flash verification result does not qualify physical controls or audio.
+
+## Start with the host build
+
+Requirements: CMake 3.20+, a C++17 compiler, Python 3.10+, and Git. The scripts use only
+Python's standard library. Linux/WSL is the reference command environment.
+
+```sh
+cmake -S . -B build-host -DCMAKE_BUILD_TYPE=Release
+cmake --build build-host --parallel 2
+ctest --test-dir build-host --output-on-failure
+python3 -S -m unittest discover -s tests/python -v
+python3 -S tools/validate_repo.py
+python3 -S tools/generate_presets.py --check
+./build-host/render_scenarios renders/first
+./build-host/render_scenarios renders/repeat
+python3 -S tools/validate_audio.py renders/first --repeat renders/repeat
+```
+
+The host adapter object builds use an explicit stub. They catch C++ integration mistakes,
+not compatibility with an actual libDaisy revision, interrupt behavior or electrical behavior.
+
+## Build the two target images
+
+Use DaisyExamples' existing root libDaisy at `../../libDaisy`, verified against
+`deps.lock.json`. Run qualification in a clean isolated checkout; the helper rebuilds
+the library with explicit qualification flags. See [Codex execution](docs/CODEX_EXECUTION.md).
+
+```sh
+python3 -S tools/verify_dependencies.py ../../libDaisy
+python3 -S tools/build_target.py --libdaisy ../../libDaisy
+```
+
+The default build is `BOOT_NONE`. Successful builds must fit the project's 128 KiB
+internal-flash qualification policy. Oversized images fail; changing boot layout requires
+a deliberate bootloader decision. `BOOT_SRAM` and `BOOT_QSPI` are explicit build options,
+not assumptions about the board in front of you. The build tool never flashes hardware.
+
+Do not use a host executable as a firmware image. Do not use an old successful CI result
+for the new source. The build helper records its transcript during the build and emits a successful
+qualification manifest with source/image hashes, tool versions and dependency gitlinks
+only after both real ARM images pass its checks.
+
+## Development and playing references
+
+- [Detailed plan](docs/00_EXECUTION_PLAN.md) and [foundational findings](docs/01_FOUNDATION_REVIEW.md).
+- [Eight-file Mermaid system reference](docs/system/README.md), covering ownership,
+  algorithms, timing, controls, hardware, presets and evidence gates.
+- [User manual](docs/USER_MANUAL.md), [tutorial presets](docs/PRESETS.md) and
+  [quick reference](docs/QUICK_REFERENCE.md).

+  [DVPE decision](docs/DVPE_INTEGRATION.md).
+- [Source ledger](third_party/manifest.json), [dependency pin](deps.lock.json) and
+  [R0 preservation inventory](references/r0_manifest.json).
+
+## Deliberately not implemented
+
+No persistent user save, sample engine, 64-step paging, deep parameter locks, external
+clock following, external audio lane, USB MIDI transport or Hydrasynth-specific
+integration. Beat's CV and Gate outputs are commanded off and its audio inputs are ignored.
+Those ports are exercised by Field Truth first. A/B/Fill is present as a candidate;
+P0 hardware acceptance remains open.
+
+P0 must establish controls, audio, CV/Gate, MIDI and timing on the actual Field. Only then
+promote Beat to the P1 hardware trial. Longer patterns, more voices and two-box integration
+follow measured standalone performance, not the number of folders in this repository.
+
+## License and references
+
+The owner's root license choice remains unselected; this package does not invent one.
+See `LICENSE_STATUS.md`. Commercial manuals, their diagrams and factory patterns are
+not redistributed. Their instructional approaches informed the original manual and
+tutorials, not the implementation of their products.

+# HydraPulse Field: foundation review and implementation plan
+Date: 2026-09-07. Candidate version: 0.2.0-dev. Target: Denys/DaisyExamples, field/HydraPulse.
+This plan is followed by implementation in this package, not a request for another planning session.
+
+## 1. Preserve and establish the baseline
+Verify the supplied R0 ZIP checksum. Preserve every one of its 29 files under references/r0.
+Inspect clock, pickup, sequencer, tests, manifests and existing CI before changing them.
+Use a new additive field/HydraPulse folder. Do not delete Denys/HydraPulse-Field or rewrite history.
+On the connected Codex checkout, inspect the actual target HEAD/tree, nearest AGENTS.md, root README,
+.gitmodules, CI scripts, build configuration and destination conflicts before applying the package.
+The old remote SHA in the conversation is historical evidence, not a current HEAD assertion.
+
+## 2. Audit boundaries before features
+Check invalid numeric inputs, retuning semantics, sample timing, callback ownership,
+cross-context communication, key mapping, mute/retrigger transitions and actual QA coverage.
+Attach every material finding to a failing test or a specific absent implementation.
+Retain the tested Pattern16 and StepSequencer interfaces; repair clock/pickup input handling.
+Do not confuse a provenance validator's string checks with upstream verification.
+
+## 3. Write the system reference before integration
+Produce individually editable Mermaid files and companion explanations for system context,
+firmware ownership, audio algorithms, clock/transport, control gestures, Field I/O, preset
+transactions and verification. Use actual source symbols and make deferred features explicit.
+Review diagrams against the resulting implementation and provide a renderer command for Codex.
+
+## 4. Implement reusable primitives and host tests
+Keep all musical/DSP logic independent of libDaisy. Implement finite ramps, deterministic noise,
+a sine lookup, bounded AD envelopes, a swing-aware integer clock, fixed-capacity SPSC queues,
+four voice algorithms, original tutorial presets and the direct-control state machine.
+Test invalid inputs, finite outputs, decay, replay, schedule error, transport, bank transitions,
+overflows, held-button gestures, parameter pickup and no-allocation processing.
+Do not add a generic plugin/browser/modulation ecosystem merely for hypothetical portability.
+
+## 5. Implement permanent P0 diagnostics
+Separate firmware target: passthrough; keyboard edge/seen masks; knob/CV reporting;
+Gate In counts; MIDI receive counts; manual DAC code selection; outputs normally off.
+Release-to-arm then hold SW1 for output tests; SW2 alone for LED/OLED test.
+Instrument the callback with the Seed testpoint and libDaisy CpuLoadMeter.
+Label timer load as callback-body instrumentation, not total interrupt occupancy.
+Preserve cold-start boot metadata for later serial connection; do not infer electrical reset cause.
+
+## 6. Implement Beat Core as a bench candidate
+Four synthesized voices: Hammer, Crack, Steel and Arc. Three 16-step banks: A, B and Fill.
+One home screen; hold Shift for direct actions; release returns home. No persistent menu stack.
+Four common sound controls, fixed tempo/swing/drive/master knobs, soft pickup after selection.
+A/B changes at the next bar, momentary Fill at the next step, smooth mutes and panic.
+Eight original tutorial presets, from blank to dense. Preset browsing never loads automatically.
+The user's new instruction authorizes producing this candidate without waiting for P0 hardware
+results. It does not authorize marking P0 passed: performance deployment still follows P0.
+
+## 7. Use verified Daisy infrastructure, avoid collateral changes
+Use libDaisy DaisyField BSP, core/Makefile and CpuLoadMeter. Respect GNU++17 selection explicitly.
+Keep original DSP native-testable; DaisySP is not required by these particular algorithms.
+Use the target repo's build/style/test tools only after inspecting their actual versions and scope.
+Use a private per-project dependency checkout rather than repinning siblings' submodules.
+Generate truth and beat binaries into distinct build directories. Never auto-flash in CI.
+DVPE is optional: omit .dvpe until serialization, block registry and export round-trip are verified.
+
+## 8. Validate and deliver
+Execute host GCC/Clang tests, sanitizers where supported, waveform scenarios, source validators,
+package checksum checks and an additive patch application test.
+Run the real ARM compiler and libDaisy linker in Codex; preserve ELF/BIN/MAP, toolchain identity,
+dependency SHAs and build logs. Fail clearly if compiler, libraries or supported flash size are absent.
+Render Mermaid and run relevant upstream regression tools in that checkout.
+A host peripheral stub only checks application syntax/contract; it is not an ARM build.
+Deliver code, manual, preset lessons, test instructions, review and measured local result files.
+Remote publishing requires a working authorized connector or authenticated Codex git session.
+No such route is exposed in this authoring run, so remote writes are not performed.
+
+## 9. Hardware and musical acceptance
+After P0 flash, measure all physical controls, CV/Gate electrical behavior, calibrated audio,
+MIDI input and timing under display/LED/serial load. Freeze measured control mapping.
+After Beat flash, test each tutorial lesson, 60-minute dense performance, rapid retriggers,
+transport/mute/preset changes, disconnected USB, queue pressure and near-endpoint controls.
+Record worst observed callback time; initial proposed target is <50% of the 1 ms period,
+with zero observed deadline overruns. This is an acceptance target, not a measured result.
+Use calibrated loopback and listening to assess clicks, aliasing, DC, headroom and voice clarity.
+No hardware test can be manufactured by desktop compilation.
+
+## 10. Deferred growth with explicit entry conditions
+After P0/P1 acceptance: persistent storage with power-fail tests, 64-step paging, additional three
+voices, controlled destruction, then timing/clock integration and the stereo external lane.
+Add complex locks/ratchets/probability only after A/B/Fill and direct operation remain usable.
+Keep Hydrasynth-specific MIDI/CV/audio integration deferred. Do not copy manual patch settings
+or commercial pattern-book content into presets.

+# Foundation review
+## Verdict
+R0 is a useful host-test bootstrap, not a hardware instrument or a target-qualified build.
+Its existing tests miss numeric and runtime integration failures. Preserve its research;
+repair those gaps before using it as a firmware foundation.
+
+| ID | Evidence in supplied R0 | Concrete failure | Resolution in this candidate |
+|---|---|---|---|
+| F01 | SampleAccurateStepClock::SetTempoBpm unconditionally calls Reset | Repeated tempo updates can indefinitely postpone the next step | Retune preserves phase; add repeated-retune regression |
+| F02 | Clock constructor accepts zero sample rate/zero step division; tiny BPM rounds to zero after mutation | Zero-threshold clock emits constantly or zero increment stalls | Validate construction, safe fallback and transactional setters |
+| F03 | ControlPickup::Clamp uses std::clamp directly | NaN input can poison the held value and defeat capture comparisons | Ignore nonfinite physical updates; sanitize initialization |
+| F04 | HPF_CHECK_NEAR only compares fabs(error)>tol | NaN comparison is false, so an invalid numerical result passes | Explicit finite/tolerance checks and negative self-test |
+| F05 | Python tests run validators only on a valid repository | Removing a required file or corrupting provenance is not tested | Negative fixture tests for required files, presets and evidence |
+| F06 | R0 has no firmware source, only field_truth/README.md | Host CI cannot detect a target API or linker failure | Two firmware entry points, explicit target-build script and separate gates |
+| F07 | No UI/audio ownership contract exists in executable code | Concurrent display/MIDI edits could race DSP and corrupt state | Audio owns engine/UI; fixed-capacity one-producer/one-consumer snapshots and MIDI commands |
+| F08 | No sound engine or rendered scenarios | Passing integer tests says nothing about runaway audio, tails or transitions | Deterministic DSP renderer; finite/bounds/decay/transition/no-allocation tests |
+| F09 | Manifest validation checks only SHA syntax and equality | A well-formed but unfetched commit looks reproducible | Check actual git HEAD and submodule state in target preflight |
+| F10 | P0 physical key order unmeasured | A diagram could label the wrong physical key or LED | One explicit mapping table and a bench acceptance gate; no measured-label claim |
+
+## Integration judgment
+Placing the project under field/HydraPulse improves compatibility with the two-level relative
+library layout documented by upstream DaisyExamples. It does not grant tools access and does
+not establish that Denys's fork contains a particular QA framework. That fork was not readable
+through this run's public web route. No claims about its current tree are made.
+
+libDaisy's inspected tests/CMakeLists.txt actually selects a limited set of sources with UNIT_TEST
+and GoogleTest; it is not a simulator of the whole Daisy Field. CpuLoadMeter exists and measures
+callback-body time with System ticks. The generic Makefile defaults to GNU++14 and BOOT_NONE:
+both facts require explicit attention for a C++17 project and flash-size verification.
+
+## What was not reproduced
+No root license was selected. No commercial manual was copied into the repository.
+The original APE_DRAFT ZIP and two .skill files are absent from this runtime: their contents
+are not reconstructed from the handoff. The available 29-file R0 ZIP is preserved byte-for-byte.
+No current remote merge, ARM build, DFU write, or physical measurement was performed here.
+
+## Design versus proof
+Soft ramps, finite envelopes and the absence of a resonant feedback path reduce specific failure
+mechanisms. They are not a proof of click-free analog output or inaudible aliasing. Pulse timing,
+codec behavior, boot transients, noise floor and analog levels remain measured-hardware gates.
+
+## Implementation review and repaired deltas
+
+F11. The first Arc candidate reset modulation-envelope depth at an active retrigger.
+A matched-trajectory host test measured 1.42942 full-scale first-sample deviation.
+Using a 1-ms envelope rise from the current depth reduced the tested maximum to
+0.0320582. Noise-filter coefficient updates also became 5-ms ramps; the corresponding
+parameter-event deviation fell from 0.210695 to 0.0263815. These are tested scenarios,
+not a universal perceptual click guarantee. `test_transitions` guards the repairs.
+
+F12. Repeated Stop could repeatedly restart a release ramp and postpone silence.
+Envelope Release now ignores an already active zero-target release. The repeated-release
+regression reaches exact silence within its fixed test window.
+
+F13. Long telemetry records can exceed libDaisy's documented `LOGGER_BUFFER=128`.
+Boot, output, timing and queue records are now split, with bounded string widths.
+A conservative format-width test covers full 32-bit numeric values including CR/LF/NUL.
+Source: https://electro-smith.github.io/libDaisy/logger_8h_source.html
+
+F14. The upstream core Makefile's OpenOCD `program` recipe hardcodes `./build/`,
+unlike `program-dfu`, which uses `BUILD_DIR`. This project uses separate build-truth
+and build-beat directories. The integration guide therefore uses the verified
+DFU recipe only after a boot-layout decision, never the incompatible `make program`.
+Source: https://raw.githubusercontent.com/electro-smith/libDaisy/master/core/Makefile
+
+F15. Showing only the Shift legend hid tutorial selection while its modifier was held.
+The Shift display now keeps the pending tutorial name and load action visible.
+No persistent nested menu was introduced.
+
+F16. The inspected upstream application core Makefile adds `-fshort-enums`, while the
+inspected library Makefile does not. Cross-library structures containing public enums
+must not depend on inconsistent compiler layouts. This project explicitly uses
+default-width enums in both builds, appends `-fno-short-enums` after the upstream
+application rules, and asserts the public MIDI enum width. The ARM build remains
+required to verify the complete ABI; source inspection alone does not establish it.

+# Build, qualify and operate HydraPulse in DaisyExamples
+
+This integration uses the existing root libDaisy gitlink. Do not repin the shared
+submodules or rebuild a dirty/shared dependency tree with qualification flags.
+Use a clean isolated checkout of DaisyExamples; preserve the standalone repository.
+Read the repository and project AGENTS.md and `INTEGRATION_2026-09-08.md` first.
+
+## Host qualification
+
+Run from `field/HydraPulse` with CMake, GCC/Clang and Python 3.10+:
+
+```sh
+python3 -S tools/validate_repo.py
+python3 -S tools/generate_presets.py --check
+python3 -S -m unittest discover -s tests/python -v
+cmake -S . -B build-host -DCMAKE_BUILD_TYPE=Release
+cmake --build build-host --parallel 4
+ctest --test-dir build-host --output-on-failure
+cmake -S . -B build-ubsan -DCMAKE_BUILD_TYPE=Debug -DHPF_UBSAN_ONLY=ON
+cmake --build build-ubsan --parallel 4
+ctest --test-dir build-ubsan --output-on-failure
+CXX=clang++ cmake -S . -B build-sanitize -DCMAKE_BUILD_TYPE=Debug -DHPF_ENABLE_SANITIZERS=ON
+cmake --build build-sanitize --parallel 4
+ctest --test-dir build-sanitize --output-on-failure
+./build-host/render_scenarios artifacts/renders-a
+./build-host/render_scenarios artifacts/renders-b
+python3 -S tools/validate_audio.py artifacts/renders-a --repeat artifacts/renders-b
+```
+
+Clang needs its platform ASan runtime (Ubuntu 24.04: `libclang-rt-18-dev`). A runtime
+startup/link failure is not a sanitizer pass. The adapter stub checks source/API shapes;
+it cannot establish actual BSP compatibility, interrupt behavior or physical results.
+Use clang-format 10 on active C++; preserve `references/r0` byte for byte and regenerate
+`Presets.generated.h` through the generator. QAE warnings in host test utilities are
+not allocations in firmware; inspect firmware warnings against the adapter startup.
+
+## ARM qualification
+
+Inspect root `libDaisy` HEAD, status and recursive gitlinks. In a fresh checkout,
+initialize only root libDaisy and its recorded `tests/googletest` submodule. This pin's
+upstream host tests use `libDaisy/tests/Makefile`, not the newer CMake test layout.
+
+```sh
+python3 -S tools/verify_dependencies.py ../../libDaisy
+python3 -S tools/build_target.py --libdaisy ../../libDaisy --app-type BOOT_NONE --jobs 4
+```
+
+The helper force-rebuilds the library and two independent images, records tool versions,
+command lines, ELF/BIN/MAP, section sizes, hashes, and source/dependency identity.
+Truth uses `build-truth/HydraPulseTruth.*`; the instrument uses
+`build-beat/HydraPulseBeat.*`. No DaisySP is required. Keep default-width BSP enums,
+C++17, finite-math checks, and the 128 KiB internal-flash size gate. Never substitute
+host executables or bypass this gate by guessing a bootloader layout.
+
+## Flash and physical validation
+
+No CI workflow flashes hardware. Flash only when the user has authorized it, after
+identifying the actual device and matching the image to its successful manifest.
+For BOOT_NONE, internal flash starts at 0x08000000. Preserve a recovery image before
+replacing the current application. Other boot layouts require a separate device/layout
+decision. Preview `make -n APP=truth program` and verify its APP-specific ELF path.
+The intentional local `program` recipe override replaces the pinned upstream hardcoded
+`build/` path; GNU make reports an override warning. `make APP=truth program` is the
+explicit diagnostic flash action. Use `APP=beat` only after the diagnostic gate.
+
+Run Truth first. Record boot telemetry, OLED, 16 raw key indices, eight knobs, callback
+load/overruns, safe CV/Gate state, low-level stereo passthrough, clipping and silence.
+Do not flash the instrument until the physical diagnostic smoke test succeeds.
+Then load First Pulse, test Play/Stop and decay, repeated transport, all four voice
+parameters, tempo/steps/accent/voice/A-B/Fill/mutes/Panic in mono before enabling stereo.
+Retain actual operator observations and audio captures; host/ARM/flash verification
+cannot prove click-free analog sound or a complete P0 electrical qualification.
+
+## Publication and continuity
+
+Stage only HydraPulse and its narrowly necessary CI changes. Preserve the original
+candidate manifest as provenance, record every delta, and keep historical package
+results separate from current qualification. Publish through a normal branch/PR,
+verify actual CI runs and merge only passing reviewed changes. No force push or
+standalone repository changes. Report exact final commit, dependency, tests, artifacts,
+CI and hardware status. Hardware without retained observations remains NOT_RUN.

+# DVPE integration: deliberately no invented project
+
+## Current result
+
+No `.dvpe` file or DVPE block implementation is included. The two requested
+repositories are useful investigation targets:
+
+- https://github.com/Denys/DVPE_Daisy-Visual-Programming-Environment
+- https://github.com/Denys/DVPE
+
+A public README for the first project describes `.dvpe` save/load, C++/Makefile
+export and custom/nested blocks. That is not enough to establish the exact
+current serialization schema, valid block identifiers, Field control bindings,
+or generated-code behavior. A complete registry/schema/export round trip was
+not executed, and the other repository could not be qualified through the
+available retrieval route.
+
+The handwritten C++/Makefile implementation is the working development
+candidate. Omitting an unvalidated visual project is intentional.
+
+## Reusable primitives already implemented and host-tested
+
+| Candidate block | C++ source | Contract to preserve |
+|---|---|---|
+| Parameter ramp | `src/dsp/Primitives.h::Ramp` | Finite bounded target, fixed-duration linear transition, unchanged target does not restart |
+| Retrigger-safe one-shot | `src/dsp/Primitives.h::Envelope` | Attack from current amplitude, finite release, repeated release does not postpone silence |
+| Sample-domain groove clock | `src/core/GrooveClock.h` | Rational remainder, 16th-note tempo, pair-preserving swing, no tempo-reset drift |
+| Soft pickup | `src/core/ControlPickup.h` | Target crossing capture, finite input, explicit rearm |
+| Bounded event queue | `src/core/SpscQueue.h` | Single producer/consumer, N-1 capacity, release/acquire ownership, visible overflow |
+| Output-test arm | `src/core/OutputTestArm.h` | Release-to-arm, momentary hold, inhibit, not hardware fail-safe |
+| Four-voice percussion unit | `src/dsp/Voices.*` | Explicit init/trigger/render, four semantic controls, deterministic noise and finite tails |
+
+These are reusable C++ units, not registered DVPE blocks. A queue or output-arm
+primitive also needs a domain-appropriate editor interface; exposing internal
+concurrency semantics as arbitrary audio-rate graph wiring would be misleading.
+
+## Codex integration procedure after the standalone candidate is qualified
+
+1. Inspect the actual DVPE README, package manifests, schema/migration code,
+   block registry, board definitions, compiler/code generator, exporter,
+   known fixtures and tests at a recorded commit. Do not classify the project
+   from folder shape.
+2. Identify supported Field hardware and event/control/audio-rate scheduling.
+   Verify how initialization, per-block processing, per-sample processing,
+   persistent state, bounded memory and mutable parameters are represented.
+3. Map a single simple primitive, preferably Ramp, to a genuine existing block
+   definition pattern. Add complete parameter limits, rate semantics, help
+   text and error paths in the actual registry's format.
+4. Use the editor/serializer to create a small valid graph, save `.dvpe`,
+   reopen it, export code and compile against the pinned real library.
+   Compare its host numerical output with the C++ reference.
+5. Add tests for schema round trips, generated code, parameter validation and
+   mismatched execution rates. Ensure graph edits cannot introduce allocation,
+   logging or blocking in the callback.
+6. Only then compose the complete instrument graph if its scheduler/state
+   model can express transport, A/B/Fill, foreground/UI ownership and bounded
+   events without hidden unsafe glue. Otherwise keep the handwritten engine
+   and make only clearly supported blocks reusable.
+7. Record exact DVPE commit, package lock, graph schema version, generator
+   version, output diff and build results. Preserve existing projects and
+   migration compatibility; propose public registry changes separately.
+
+Do not create a fictional `.dvpe` with guessed JSON keys, omit unsupported nodes
+silently, or call a graph complete because it contains labels matching the
+instrument's modules.

+# DaisyExamples integration - 2026-09-08
+
+Status: host and ARM qualification PASS locally and on branch CI. Both firmware flashes VERIFIED on two different Seed processors. Diagnostic listening FAILED/INCONCLUSIVE on the first Seed; operator reports working instrument output, sequencer, some sounds and controls on the replacement Seed. Full musical and stereo qualification remains incomplete.
+
+## Inspected inputs and preservation
+
+- Target master: `041bfcbb7975316606ece8f1ccbacbab9c0e1482`.
+- Branch: `codex/hydrapulse-field-integration`, in an independent clone under `.worktrees/hydrapulse-integration-20260908`.
+- ZIP: `HydraPulse_DaisyExamples_0.2.0_candidate_2026-09-07.zip`.
+- Installer preflight: 151 new files, zero collisions; all payload hashes checked before installation.
+- Original workspace: 150 candidate files identical to ZIP, workflow missing; extra delivery attachments left untouched.
+- Standalone `Denys/HydraPulse-Field` main: `184db5473aea258f660604d791d305f7061671fc`, inspected through the authenticated GitHub connector. It contains newer R0 integration, a separate FieldTruth implementation, tests and research. Nothing there was changed or copied over. `references/r0` means the original supplied 29-file archive, not a mirror of current standalone main.
+- Root libDaisy gitlink retained: `85172e2b5c9abea1bf56dcd5d2c7b3f5717eb66b`; LICENSE blob `1c3a251694f1d1842c3f114508d36ca63cddf275`.
+- Nested googletest: `f5e592d8ee5ffb1d9af5be7f715ce3576b8bf9c4`.
+- No root checkpoint or HydraPulse entry in LATEST_PROJECTS was available. Nearest project documents and live source were used.
+
+## Candidate deviations
+
+1. Reuse the existing root libDaisy pin instead of adding candidate-private `cc146d5065dd8286078a662e2830bf820c37a612`. Root gitlinks and the primary dirty library checkout are unchanged.
+2. Use the pinned BSP's `dsy_gpio_write` Gate Out API; give the adapter stub the same signature and LED overloads.
+3. Make fixed-width integer `std::max` calls explicit, because ARM newlib uses a different underlying `uint32_t` type than host GCC.
+4. Use floating-point zero for LED brightness to avoid the BSP's integer/float overload ambiguity.
+5. Format active C++ with CI's clang-format 10.0.1; replace unsupported SortIncludes enum with boolean. Generated presets have formatter guards. Exclude only the immutable R0 archive from the root formatting workflow.
+6. Add direct BSP includes to the firmware translation units. QAE's per-file analysis does not follow adapter includes.
+
+7. Use `-Os` for application code: the instrument at `-O2` exceeded internal flash by 3632 bytes. Both images now link below 128 KiB without a bootloader/layout change; final forced-build manifest verified.
+8. Override the local SWD `program` recipe to use the correct `build-truth` or `build-beat` ELF; upstream libDaisy remains unchanged.
+9. Force-build helpers now create and mark directory targets old (`-o`) while forcing all objects with `-B`; the pinned upstream `mkdir build` recipe otherwise fails on a second qualification run.
+10. Add `tools/qualify_host.py` to run and log all host gates. Teach logger-width tests to accept formatter-inserted whitespace before the format string.
+11. Repair a Mermaid sequence-note semicolon parse error and replace the clock diagram layout with an equivalent flowchart to avoid overlapping edge labels. Both Markdown fences and `.mmd` sources match.
+12. Change only the OLED fault counter prefix from `E` to `#`, avoiding QAE's regex false positive on an escaped percent followed by E. Formatting remains integer-only.
+
+13. Limit final Git status collection to HydraPulse with unrelated submodules ignored. A complete ARM build had reached artifact creation but the old repository-wide status scan timed out before writing its manifest. The failure transcript is preserved; only a successful manifest qualifies the final images.
+
+14. Add Git attributes preserving archived R0 and raw acquisition log bytes across platform checkouts. Raw logs are binary-diff entries so recorded trailing whitespace remains intact.
+
+15. Match the root workflows' `actions/checkout@v7` and default credential persistence for the parent checkout. Early cleanup with `persist-credentials: false` fails on the repository's pre-existing orphan `.tmp/ai-book-sparse` gitlink, under both v4 and v7, before tests run. The ephemeral CI token has only contents-read permission; independent libDaisy checkout still removes credentials immediately. No unrelated submodule metadata was changed.
+
+## Current software evidence
+
+- `tools/qualify_host.py`: all 15 commands returned zero, with per-command logs and a JSON index.
+- Release (GCC 13.3): 14/14 CTest PASS; UBSan (GCC 13.3): 14/14 PASS; ASan+UBSan (Clang 18.0): 14/14 PASS.
+- Python: 38/38 PASS; repository/provenance, generated presets and 29-file R0 preservation PASS.
+- Host deterministic stereo render comparison PASS. No host render is a Field recording.
+- Upstream libDaisy host tests: 151/151 PASS with GCC 13.3. Clang 18 first rejected an existing GNU variable-length-array extension under upstream -Werror; no upstream source or flags were changed for the GCC run.
+- QAE: zero errors, seven advisory warnings. Two NO-START-ADC reports are per-file false positives: `InitHardware()` starts ADC before `StartAudio()`. Remaining heap/iostream reports concern host tests and the renderer.
+- clang-format 10.0.1: all 37 active C++ files match. Immutable R0 sources were not formatted.
+- Mermaid 11.12.2 / headless Edge: all eight diagrams rendered to SVG/PNG with no page errors; all eight screenshots inspected for clipped or overlapping labels. The corrected clock flowchart is readable. Desktop intrinsic-size renders only; no mobile layout claim.
+- ST-Link identified an STM32H74x/75x Cortex-M7 with a single 128 KiB internal-flash bank. Internal flash backup retained locally before any write: 131072 bytes, SHA-256 `80971a0ee9a0e019ac692308618a8300a1861e5a78102033f3162a31272dc95e`. Recovery image is not published.
+
+## ARM and flash evidence
+
+- Final `tools/build_target.py` completed successfully after rebuilding the library and both images. See `evidence/arm-build-2026-09-08.json` for exact input, compiler, dependency and ELF/BIN/MAP SHA-256 records.
+- Runtime source digest: `24e035a726a12d2ad72f8b69d1491a3ad17267acbbcf1a38135e8937bd8250cc`.
+- FieldTruth (`HydraPulseTruth.bin`): 107280 bytes; SHA-256 `72a21e32621174f5d66cbcade3711b21d5810711813b27fc405c696e48bdab60`.
+- HydraPulse (`HydraPulseBeat.bin`): 122320 bytes; SHA-256 `6b0d5b518b20ad57720755ee6330b684b2e905704ebaa35d906225a9173dc458`.
+- Compiler: GNU Arm Embedded 13.2.1, Ubuntu package; Cortex-M7 hard-float; BOOT_NONE. Application `-Os`, library `-O3`, both finite-math qualification flags and default-width enums.
+- ELF sections (text/data/bss bytes): Truth 104252/2988/86116; Beat 113492/8788/85196. Linker usage: Truth FLASH 107280, SRAM 71160, RAM_D2 17224; Beat FLASH 122320, SRAM 76040, RAM_D2 17224; BACKUP_SRAM 12 each. Neither application allocates SDRAM or QSPI sections. The linked SRAM includes reserved heap/stack; no measured stack high-water claim.
+- Linker emits enum attribute warnings from GNU runtime objects. Actual application and libDaisy translation units use int-width enums and application static assertions enforce the public BSP MIDI enum width. The warning is retained in logs. Newlib nosys stubs also warn about unsupported POSIX I/O; no such I/O is performed in audio callbacks.
+- Diagnostic ELF matched current runtime sources and successful manifest immediately before flashing.
+- Native Windows OpenOCD 0.12.0 with ST-Link serial `0020000A5553500920393256`: **Programming Finished / Verified OK / Resetting Target**, exit 0. The native tool executes the same inspected APP-specific ELF recipe because USB/SWD is attached to Windows, while compilation runs in WSL.
+- Instrument flash: VERIFIED on the replacement Seed after the operator explicitly requested loading HydraPulse despite the unresolved diagnostic audio result. This is an operator-authorized diagnostic continuation, not a passed P0 promotion. Basic musical output is now operator-reported on the replacement Seed; full P0 and all-gesture audio acceptance remain incomplete.
+
+## Initial hardware runtime capture
+
+The flashed diagnostic enumerated as Daisy USB CDC COM5 (`0483:5740`) and emitted
+`build=24e035a726a1`, 48 kHz / 48-sample blocks, CPU 400 MHz and tick clock 200 MHz.
+A 45-second capture reports max load 28 per mille, zero overruns and zero late starts.
+Raw pressed indices captured: 0, 1, 2, 8, 9. This is not all sixteen physical keys.
+CV/Gate output commands were zero; audio input peaks were approximately 0.70 full scale
+in both channels. Input telemetry alone does not prove analog output or passthrough quality.
+The initial serial backlog contains one malformed record and a cumulative drop count of
+857. Preserve this capture; do not classify it as clean complete hardware validation.
+No intentional MIDI stimulus, knob endpoint sweep, all-key mapping or operator listening
+result was recorded during the initial captures. The later operator report and replacement-Seed flash are recorded below.
+
+A second 30-second acquisition discarded the connection backlog before capture.
+It contains 0 malformed records, with callback delta 29560 and drop delta 0.
+Overrun and late-start counters remained zero. The cumulative drop counter was 3058 at capture start and 3058 at its end; disconnected time is not a measured clean interval.
+Raw logs and derived summaries for both acquisitions are retained without byte normalization.
+
+## Operator report and replacement Seed
+
+The operator reported a responsive OLED, key LEDs responding on press, and both switches affecting the display. Knob LEDs did not change brightness; inspection confirms FieldTruth drives only key LEDs, so knob-dependent LED brightness is not implemented. This does not prove all eight analog knob endpoints.
+
+The operator heard either no audio or a whistle with FieldTruth, then replaced the Seed processor. An older synth on the replacement reportedly did not whistle. The cause is unresolved; input passthrough routing, the first processor and the firmware have not been discriminated by measurement. Do not mark diagnostic audio PASS.
+
+The operator explicitly requested loading HydraPulse on the replacement. SWD confirmed a different processor UID (`002e0044 33305110 39383339`, versus the original `001c003b 3330510f 39383339`), still STM32H74x/75x with 128 KiB flash. A separate full internal-flash backup was retained locally before writing: 131072 bytes, SHA-256 `59a8481b89a5f621eb6f8a14318227e1fccdee24824bb562b9ed1e2f7d1735a7`. Neither recovery image is published.
+
+HydraPulseBeat's local qualified ELF was programmed, verified and reset through ST-Link, exit zero. The replacement enumerated on COM7 and emitted `app=beat build=24e035a726a1`, 48 kHz / 48 samples, CPU 400 MHz. A 55-second capture had no malformed records, max reported load 123 per mille, zero faults/overruns/late starts and zero MIDI/snapshot queue drops. These counters do not establish audible behavior or physical gesture coverage. The subsequent operator listening report is recorded below; the capture itself does not verify listening results.
+
+## Subsequent operator smoke result
+
+After the replacement-Seed HydraPulse flash, the operator reported that output now works correctly, the sequencer works, and at least some sounds work. SW1/SW2, keys, key LEDs, knobs and volume were reported working. This is a positive basic instrument smoke result reported by the operator, not a recorded or independently measured audio test.
+
+The operator suspects the previous processor was faulty. That is plausible but unproven: the earlier listening test used FieldTruth passthrough and the successful later test uses HydraPulse synthesis on a different Seed. A controlled comparison or electrical measurement is still needed to identify the cause of the original whistle.
+
+Knob LEDs are not implemented in either firmware image. Both display routines first clear all LED channels, then populate only key LEDs; the instrument additionally sets the two switch LEDs. No knob LED brightness is written. Their dark state is therefore expected firmware behavior, not evidence that the knobs or their LEDs are defective.
+
+Still unverified: all four voices individually; repeated Play/Stop and decay-to-silence; detailed click/DC/clipping checks; each musical gesture (accent, voice select, A/B, Fill, mute and Panic); measured stereo channel/routing behavior; all sixteen raw key mappings and all eight knob endpoints; full CV/Gate/MIDI P0 measurements. Do not infer these from the general positive smoke report.
+
+## Remote software evidence and source identity
+
+At source commit `fdd22f363b04447ceb92c2a2774ae9d96edc54df`, the [branch qualification run](https://github.com/Denys/DaisyExamples/actions/runs/34232758870) passed all three host modes and both ARM builds. [Build All](https://github.com/Denys/DaisyExamples/actions/runs/34232764124) and [Fix Style](https://github.com/Denys/DaisyExamples/actions/runs/34232764041) passed on the PR. Subsequent changes to this evidence report do not change runtime source.
+
+All six downloaded CI ELF/BIN/MAP artifacts matched their manifest sizes and SHA-256 values. See `evidence/ci-arm-build-2026-09-08.json`. Local and CI manifests differ in the raw line endings of `src/app/Presets.generated.h`: CRLF locally and LF in Git. All 22 build inputs are identical after newline normalization; `evidence/commit-source-bridge-2026-09-08.json` records that comparison. This changes the embedded source ID (`24e035a726a1` local, `41e814118b1e` CI). For each application, the two BIN files are byte-identical after replacing only that embedded ID; ELF/MAP also carry build-directory/debug paths. Keep the local manifest for the images actually flashed; do not substitute CI hashes for them.
+
+## Earlier attempts retained for traceability
+
+- Candidate-after-install Python: 38/38 PASS.
+- Candidate-after-install GCC 13.3 Release: 14/14 CTest PASS.
+- GCC 13.3 UBSan: 14/14 CTest PASS.
+- Deterministic host sonic scenarios: PASS for two runs; these are not Field recordings.
+- First ARM qualification: libDaisy compiled with GCC ARM 13.2.1; firmware failed on the target-specific issues listed above. Failure transcript retained under `artifacts/2c2ca122dc96/BOOT_NONE/build.log`.
+- First Clang ASan+UBSan link failed because libclang-rt was absent. Runtime installed; rerun required.
+- QAE first scan: 3 errors, 7 warnings. Two missing-direct-include errors and one regex false positive interpreting the escaped percent before `E` as float printf. No float printf support was added.
+- ST-Link USB serial `0020000A5553500920393256` detected. Daisy USB CDC not yet detected. No flash, runtime, physical control or analog audio result is implied.
+
+Raw run logs and renders are under `artifacts/integration/`. `PACKAGE_MANIFEST.json` is the original ZIP inventory, not a hash assertion about the adapted working tree; run `install_additive.py` only against the untouched extracted candidate. Current source identity and image hashes are recorded by the final ARM manifest. No `dist/` binaries are regenerated by this task: the repository's generic dist helper searches `build/`, while these two deliberately separate images are uploaded by HydraPulse CI.

+## 3. Broken Grid
+**Lesson:** Hear syncopation without probability.
+**Change placement, not machinery.** Compare A and B at a fixed tempo. The grid is deterministic: the variation comes from note placement, not probability.

+## 4. Alloy Swing
+**Lesson:** Compare straight and delayed offbeats.
+**Hear swing in pairs.** Compare knob 6 at straight 50% long-step share with the stored swing setting. Leave the note pattern unchanged during the comparison.

+## 5. Arc Study
+**Lesson:** Explore phase modulation, tune and decay.
+**Learn the fourth voice.** Mute the other voices to hear Arc. Move Tune first, then Character. Try a short decay for a dry strike and a longer decay for the modulation tail.

+## 6. Night Shift
+**Lesson:** Perform A/B, mutes and momentary Fill.
+**Perform an arrangement.** Let A repeat, request B, then borrow Fill. Drop one voice with Shift + mute, bring it back, and use Drive as a temporary intensifier.

+## Host WAV scenario
+Each ten-second host render starts the tutorial, queues B at 3 s, requests Fill at 5 s, releases Fill at 6 s, and panics at 7 s. The final seconds test silence. Master is 0.70 for the renderer, not a value loaded by the tutorial. Blank Canvas is intentionally silent.
+The supplied WAVs are native C++ renders, not recordings from Daisy Field. Matching hashes show repeatability in the tested host build, not bit equality across processors.
+## Blank notes sheet
+Record the voice values above, then three sixteen-step grids per voice. Include tempo, swing, drive, master, mutes, the firmware hash and anything learned during the lesson. A/B changes occur on the next bar; Fill continues the current phase.

+# Qualification plan: software evidence, then hardware truth
+
+## Acceptance model
+
+A result has an evidence class, a tested object and a scope. Use
+`VERIFIED | DERIVED | PROPOSED | ASSUMED | HOLD | NOT_RUN`.
+`VERIFIED` does not mean universally correct: name the exact source/build,
+procedure, stimulus, duration, fixture and observed result.
+
+The stages are independent:
+
+| Gate | Required evidence | What it does not prove |
+|---|---|---|
+| R0/core | Host tests, negative tests, exact scenario replay | ARM timing or peripheral operation |
+| Adapter contract | Actual firmware translation units compiled against declared fake BSP; application routing tests | Actual libDaisy ABI, UART, codec, DMA, linker |
+| ARM | Exact pinned dependencies, full rebuild, ELF/BIN/MAP and hashes | Power-up, analog performance or real-time margin |
+| P0 | Measured Field I/O, mapping and callback evidence with raw artifacts | Musical usability of four voices |
+| Beat qualification | Target stress, audition, interface tests and timed loopback | Full seven-voice product or Hydrasynth integration |
+
+The delivered Beat code is an implemented candidate, not a declaration that
+P0 has passed. Review `VALIDATION.md` for checks actually executed.
+
+## A. Native automation
+
+Run the commands in `CODEX_EXECUTION.md`. The current CTest registration is the
+source of truth for executable names.
+
+### Pattern and transport
+
+Exercise all valid and invalid track/step bounds, toggle twice identity, clear
+isolation, deterministic property stress, stable ordering, 16-step wrap, stopped
+silence, start at step zero, repeated Start/Stop, A/B bar-boundary switching and
+momentary Fill return. Check A/B editing versus the playing bank separately.
+A mute should neither delete steps nor reappear as a latent stuck trigger.
+
+Test simultaneous bank requests, Fill edge near step zero, preset confirmation
+while playing, and stopping immediately before a boundary. Presets must refuse
+to load while running. Start/stop/cancel must remain meaningful while a preset
+transaction is fading.
+
+### Clock
+
+Check 44.1/48/96 kHz and integer/fractional BPM; compare rational ideal event
+positions, not wall-clock execution speed. Error against the sample-quantized
+schedule is at most one sample in the tested fixed-tempo scenarios. Test
+repeated identical tempo updates, changed tempo mid-interval, extreme legal
+tempo, phase preservation and swing pair length. Swing must commit at a pair
+boundary without shifting the pair's total duration. Check invalid rates,
+NaN/Infinity, out-of-range tempo and transactional rejection.
+
+Extend the long-run test to a representative hour or an equivalent event-domain
+reference before any external clock implementation. No MIDI-clock drift claim
+exists for a core that deliberately ignores external clock.
+
+### Control gestures
+
+Use deterministic 1 kHz stable input frames. Cover tap release, hold threshold
+minus/at/plus one tick, release ordering, keys already held when Shift is
+pressed, Shift released before the key, both switches released in either order,
+repeated panic, switching voices with knobs elsewhere, and preset-load pickup.
+Confirm no modifier gesture leaks a normal step toggle on release.
+
+Check the exact beginner path without a menu browser:
+select voice, enter steps, edit four voice controls, Play.
+Confirm a step hold toggles accent once, not at every scan. Clear requires a
+stopped transport and a one-second hold. Preset confirmation requires stopped
+transport; preview expires after five seconds.
+
+### Concurrency and bounded work
+
+The audio callback owns controls, Engine and DSP. Foreground is the sole
+producer of MIDI commands and the sole consumer of UI snapshots. Tests include
+queue capacity, wrap and 200,000 ordered producer/consumer transfers. Capacity
+is N-1, not N. Overflow must be visible and must never corrupt adjacent state.
+
+The callback drains at most eight ordinary MIDI commands per block. Urgent
+stop/panic bypasses the ordinary queue and flushes at most its fixed capacity.
+The no-allocation test watches callback-equivalent engine/controller processing.
+Review the real firmware callback for accidental logging, display, storage,
+formatting, heap allocation or blocking calls as well. A passing heap hook
+does not detect every possible third-party allocation or interrupt stall.
+
+### DSP and sonic scenarios
+
+Render each voice across the parameter corners and long tails. Test finite
+output, normalized bounds, zero-input silence, tail convergence, frequency
+range limits, parameter ramp endpoints, repeated release, rapid retrigger and
+preset transitions. Each voice has an independent deterministic noise seed.
+
+Use matched state trajectories to isolate discontinuities:
+run two identical voices; apply a retrigger or parameter jump to only one; compare
+the first affected sample against the uninterrupted trajectory. A large raw
+adjacent-sample difference in a noisy snare is not automatically a click.
+The current differential regression threshold is 0.08 full scale for the
+selected retrigger cases, with explicit test fixtures and recorded maxima.
+It is not a universal psychoacoustic audibility threshold.
+
+The first candidate failed this test because Arc reset modulation depth
+instantly. The repair ramps its transient envelope from current state and
+smooths the noise-filter coefficient. Keep the before/after regression evidence.
+
+`render_scenarios` renders eight deterministic ten-second stereo scenarios:
+A starts, B is requested at 3 s, Fill is held from 5 to 6 s, and panic occurs
+at 7 s. Check the last second is silent. Two runs on the same compiled object
+must produce identical PCM and metrics. Check all samples/metrics are finite,
+all eight files have the documented format, blank preset is silent, nonblank
+presets have energy, final faults are zero and peak is below 0.737 normalized.
+No bit identity across different architectures/compilers is promised.
+
+Retain peak, RMS, DC mean, maximum adjacent delta, tail peak and fault counts,
+but do not mistake these six metrics for a complete sound-quality test.
+Before musical release add: oversampled reference comparison, alias-energy
+sweeps, spectral-centroid/band-energy scenarios, pitch/decay tolerance checks,
+channel balance, and target/host numerical comparison under documented
+floating-point tolerance. The present Arc and saturation path is not oversampled.
+
+### Sanitizers and build variants
+
+Run Release, Debug+UBSan, Debug+ASan+UBSan, and a second compiler. Build both
+firmware translation units under the host contract check. Verify the intentional
+NaN-negative test exits for its assertion, not a sanitizer startup failure.
+Host memory/threading tests do not prove interrupt or DMA/cache coherence.
+
+## B. Repository, documentation and evidence tests
+
+Validate generated preset freshness, original R0 hashes, full dependency-pin
+format, source/provenance entries, isolation of the host core from BSP includes,
+all required files and all eight Mermaid source/Markdown pairs.
+
+Python negative tests must reject malformed/nonfinite presets, inconsistent
+accent masks, duplicate/malformed telemetry, unqualified hardware evidence,
+missing/hash-mismatched raw artifacts, unsafe paths, conflicting destination
+files and symlink traversal. Installer conflict detection is a complete
+preflight; unrelated destination content must remain byte-identical.
+
+After integration verify actual recursive dependency gitlinks, cleanliness,
+license blob and real required API files. This is deliberately separate from
+offline JSON validation. Render all Mermaid diagrams with the real CLI and
+review them. The manual, control map and factory data must agree with code.
+Check all documented gestures by test, and all rendered display strings for
+the 128x64 layout.
+
+The inspected logger uses a 128-byte message buffer. Test conservative maximum
+numeric widths, string precision and room for CRLF/NUL; split telemetry rather
+than relying on silent truncation.
+
+## C. Actual ARM qualification
+
+Build both Truth and Beat against the pinned dependency. Save compiler version,
+tool paths, full source fingerprint, parent Git SHA and dirty state, recursive
+gitlink records, flags, full log, link map, section sizes and image hashes.
+
+Verify no unintended host stub include path enters the ARM command. Confirm
+default-width enums on both sides of public MIDI API boundaries. Inspect
+float ABI/CPU flags, linker memory layout, static allocation and stack reserve.
+Do not accept source pinning alone as bit-reproducible toolchain evidence.
+
+For the selected actual Seed/bootloader, verify that the compiled APP_TYPE
+matches the programming method. Check internal-flash bounds for BOOT_NONE;
+otherwise make an explicit bootloader/layout decision. Do not increase limits
+on the assumption that an undocumented memory region happens to work.
+
+## D. P0 Field Truth bench sequence
+
+Start with Truth, no connected CV/Gate destination, and muted/low monitoring.
+Use the actual manufacturer's board documentation for electrical limits.
+Hydrasynth and DFAM manual voltages are not Field specifications.
+
+Record Field/Seed revisions and identifying photos, power configuration,
+firmware SHA-256/build ID/APP_TYPE, operator, date/time, temperature when useful,
+measurement instruments and settings, leads/probes/loading, audio interface
+gain/sample rate, fixture wiring and calibration checks. Keep raw captures;
+derived plots or a filled checklist alone are insufficient.
+

+| DISPLAY | Individual controls and SW2 Vegas mode, photos/video | All required LEDs and OLED pixels/status fields exercised; map recorded |
+| AUDIO | Calibrated interface loopback then Field loopback, stimuli and raw stereo WAVs | Gain, noise, headroom/clipping, crosstalk and routing characterized relative to baseline |
+| TIMING | Scope/logic analyzer on qualified timing testpoint, telemetry, stressed UI/MIDI | Callback interval, maxima and observed deadline margin measured with fixture details |
+
+The firmware's Seed testpoint use is a **proposed probe route**, not proof that
+it is conveniently accessible on an assembled Field. Inspect the actual board
+and continuity first. Do not attach a probe to a presumed unused signal based
+on a package name. If unavailable, choose an electrically safe verified
+alternative and record the code/fixture change.
+
+`SetCvOut*(0)` is a commanded minimum DAC code, not a measured zero-volt
+guarantee. The momentary output interlock requires an initial release of SW1,
+then SW1 held alone; SW2 inhibits output testing. It is software logic and
+cannot remove voltage after a CPU crash. Use an appropriate external test
+fixture and disconnected load.
+
+The gate input is polled once per 1 ms callback. Pulses narrower than that can
+be missed; characterize it rather than describing the diagnostic as a
+sample-accurate external clock receiver. Future clock input needs a separately
+qualified capture/timestamp design.
+
+### Proposed engineering thresholds, to ratify against the fixture
+
+These are project acceptance targets, **not measured results or manufacturer
+specifications**:
+
+- Zero unexpected resets, fault counts, telemetry/key losses, or unexplained
+  I/O changes during the normal diagnostic session.
+- Maximum instrumented callback body below 0.5 ms at 48 samples/48 kHz under
+  worst exercised UI and MIDI activity; zero observed >1 ms body intervals and
+  zero reported >1.5 ms start gaps. Measure full IRQ/DMA overhead separately:
+  the callback probe does not include work outside the application callback.
+- Knob endpoint residuals/pickup tolerance ratified from measured spread; do not
+  hardcode an arbitrary claim of exact 0.000/1.000 physical endpoints.
+- CV output monotonicity and residual within 1% of the **measured** span after
+  affine fitting, unless the hardware requirement calls for tighter calibration.
+  This target is not sufficient for claiming precision 1 V/oct tuning.
+- Audio round-trip gain repeatability within 0.2 dB under an unchanged fixture,
+  no unexplained channel reversal, and clipping/noise/crosstalk boundaries
+  explicitly measured. Choose absolute performance limits only after measuring
+  the direct-interface baseline and establishing required source/load levels.
+
+Do not convert an untested item into PASS to reach an aggregate milestone.
+Use `hardware/p0_record.template.json`, add real metadata and hashed raw files,
+then run `tools/validate_evidence.py`. That validates records, not their truth.
+
+## E. Beat Core on-hardware qualification
+
+After credible P0: flash the separately hashed Beat build; verify all controls
+from the manual, voice identification, master pickup and stopped boot. Check
+initial master .25 does not become a high physical-knob value without pickup.
+
+Run every preset and full A/B/Fill scenario. Compare recorded target output
+with deterministic host renders after removing measured latency and fixture
+gain; define numerical/spectral tolerances before judging. Listen on conservative
+monitoring levels for zipper noise, retrigger discontinuities, truncation,
+stereo imbalance, persistent tails, aliasing and unintended ringing. Intended
+percussive attacks and saturation must not be mislabeled as arbitrary faults.
+
+Exercise rapid accents, long decays, all voices, high drive, parameter sweeps,
+mute/unmute, multiple gestures, preset loads, repeated Panic, MIDI bursts,
+USB disconnected/connected and prolonged idle. Suggested initial soak is
+60 minutes with full raw error/callback summaries and representative scope/audio
+captures; longer reliability work remains a product gate.
+
+For every audible defect preserve: build ID, preset, knob values, gesture/MIDI
+sequence, time range, raw audio and shortest deterministic host reproducer.
+Do not tune a limiter to hide the fault without fixing its cause.
+
+## F. Deferred qualification, not hidden promises
+
+No current claims for persistence/power-loss recovery of saved patterns,
+seven voices, sampling, probability/ratchets/microtiming/locks, MIDI clock sync,
+CV musical modulation, audio-through, Hydra-specific integration, or a valid
+DVPE graph. Add each as a separate testable requirement after the independent
+instrument proves useful.
+
+This plan and its accompanying test code are not an independent audit. Formal
+musical release still needs actual hardware evidence and a separate review
+appropriate to the intended distribution.

+# HydraPulse Field
+## Player's manual | 0.2.0 candidate | 7 September 2026
+
+### Read this first
+
+HydraPulse is a standalone four-voice drum instrument for Daisy Field. Its normal job is
+simple: choose a drum, enter a one-bar rhythm on sixteen keys, shape its sound, and play.
+The first screen is the playing surface. There is no project browser, machine browser,
+patch hierarchy or required desktop editor.
+
+This manual describes the implemented candidate, not a measured production instrument.
+Two separate programs are supplied as source: **Field Truth** for bench checks and
+**Beat Core** for music. Run and record Field Truth before promoting Beat to normal use.
+No physical control mapping, electrical range, audio measurement or target callback
+deadline has been verified in this delivery. Read the build report for the particular
+binary you are about to use.
+
+Do not connect CV/Gate equipment during the first boot. Lower the external mixer,
+speaker or headphone amplifier before connecting audio or replacing firmware. A software
+limiter is not hearing protection and cannot prevent power-on codec transients.
+Use the Field board's own documented supply and connection requirements. The supply,
+signal ranges and tolerance statements in the Hydrasynth and DFAM manuals do **not**
+describe Daisy Field.
+
+Firmware replacement can overwrite another application or a resident bootloader.
+Follow the boot-layout checks in the Codex guide; do not select a flash address by guesswork.
+
+## 1. First sound and first beat
+
+### Starting condition
+
+Beat starts stopped on **Blank Canvas**, bank A, with Hammer selected. All pattern banks
+are empty. No notes are generated until you audition a voice, receive a supported MIDI
+trigger or start a pattern containing steps. Parameters have stored initial values.
+Master starts at 25% of its software range, regardless of the physical knob position.
+
+The eight knobs use **pickup**. A knob must pass through its stored value before it
+takes control. This prevents selecting a new drum or loading a tutorial from yanking
+that sound to the old knob position. Move slowly through the stored percentage shown
+on the screen, then continue editing. A pickup can occur within about 1.5% of the target;
+it is not an encoder.
+
+### Make a kick pattern
+
+1. Hold SW2, tap key 1, then release SW2. This selects Hammer; while stopped, selection
+   also auditions it.
+2. Tap keys **1, 5, 9 and 13**. Release each key promptly. Their LEDs show four active steps.
+3. Move knob 1 through the displayed Tune value, then lower it for a deeper body.
+4. Move knob 2 through Decay, then shorten the tail until the hits leave useful space.
+5. Tap and release SW1 to start. Step 1 occurs at the next audio sample after the
+   transport action is accepted. The step LEDs show the moving play position.
+6. Adjust the external listening level conservatively. Use knob 8 for the instrument's
+   software Master once its pickup target has been crossed.
+
+### Add snare and hat
+
+Hold SW2, tap key 2, release SW2. You are editing Crack without changing the kick pattern.
+Tap keys 5 and 13 for a backbeat. Then select Steel with SW2 + key 3 and enter a few
+off-beat or alternating steps. Press SW1 to stop when you need time to listen to a single
+voice; selecting a voice while stopped auditions it without requiring a sequencer step.
+
+A normal step action happens **on key release**, not on initial press. Holding the key
+for 400 ms has a different purpose: accent. This distinction lets the same sixteen keys
+edit a complete one-bar rhythm without sacrificing step visibility.
+
+## 2. The panel
+
+Key numbers in this manual are **logical steps 1–16**. The provisional adapter uses
+libDaisy keyboard indices 0–15 in order, with LEDs A1–A8 then B1–B8. Physical row/position
+assignment must be checked on the actual Field. Field Truth logs raw indices so that
+this mapping can be corrected in one place: `firmware/FieldAdapter.h`.
+
+### Eight knobs, one stable meaning
+
+| Control | Meaning | Behavior |
+|---|---|---|
+| Knob 1 | Tune | Selected drum's base frequency; logarithmic mapping |
+| Knob 2 | Decay | Selected drum's amplitude-decay time; logarithmic mapping |
+| Knob 3 | Character | Selected drum's tonal/noise/modulation balance |
+| Knob 4 | Level | Selected drum's linear level |
+| Knob 5 | Tempo | Internal tempo, 40.0–240.0 BPM in 0.1-BPM increments |
+| Knob 6 | Swing | Long/short sixteenth pairs, 50–70% long-step share |
+| Knob 7 | Drive | Global pre-saturation gain |
+| Knob 8 | Master | Global software output level |
+
+The display shows voice parameters as normalized percentages. It does not claim that
+50% Tune means 50 Hz, or that 50% Decay means half the maximum time. The musical ranges
+are in the voice chapter. Parameter targets normally ramp over five milliseconds;
+musically deliberate oscillator/noise content is not removed by that smoothing.
+
+### Two switches
+
+**SW1:** tap and release for Play/Stop. Holding SW1 alone does not create another menu.
+
+**SW2:** hold for Shift; release to return to Home. Shift is momentary, not a latched mode.
+The palette labels the available actions. Knobs retain their usual meanings.
+
+**Both switches:** hold together for 500 ms for Panic. The transport stops, Fill is
+released and voices enter a short release. Keep both released before using Play again.
+The chord cannot accidentally start transport when its switches are released in either order.
+
+### Shift palette
+
+| While holding SW2 | Action |
+|---|---|
+| Key 1 / 2 / 3 / 4 | Select Hammer / Crack / Steel / Arc; audition only while stopped |
+| Key 5 / 6 | Edit A / B and request it for playback |
+| Key 7 | Edit the Fill bank without forcing it into playback |
+| Hold key 8 | Use Fill for steps that occur while held |
+| Key 9 / 10 / 11 / 12 | Toggle the four voice mutes |
+| Hold key 13 for one second | Clear the selected track in the edited bank, stopped only |
+| Key 14 / 15 | Preview previous / next tutorial preset, stopped only |
+| Key 16 | Confirm the displayed tutorial load, stopped only |
+
+Release a Shift key and Shift in either order: it will not leak an ordinary step edit.
+For a Fill performance gesture, keep both SW2 and key 8 held. Releasing either ends
+the request. Clear and preset loading do not operate while transport is running.
+
+## 3. Reading Home
+
+The top line shows **RUN/STOP**, the edited bank and the last bank actually played.
+`A>B`, for example, means you are editing A while B supplied the last emitted step;
+the arrow is an edit/play relationship, not a copy command. The implementation's
+snapshot also exposes the queued A/B bank for development tools.
+
+The next line shows selected voice, current step number and a Fill-request indicator.
+Tune/Decay and Character/Level follow. A global line shows swing share, drive and master.
+The tutorial name or pending-load prompt is below them.
+
+`PICKUP` is a hexadecimal diagnostic mask: bit 0 is knob 1, bit 7 is knob 8.
+A set bit means that knob has not picked up its target. This compact display is
+functional but not a polished directional pickup guide. Move the relevant knob
+through its stored value; do not interpret the mask as an error counter.
+
+`MUTE` uses bits 0–3 for Hammer, Crack, Steel and Arc. `CPUmax` is the largest callback
+load measured by the firmware since initialization. `E` counts detected DSP faults.
+A zero error counter is not a substitute for a scope trace, nor is the displayed
+callback load a whole-system worst-case execution proof.
+
+Ordinary active steps are dimmer than accents. The current playing step is bright.
+In Shift, the first four LEDs indicate voice selection. The screen palette takes
+priority over the Home information; a preset preview remains visible in its bottom lines.
+
+## 4. Rhythm, accents and variations
+
+### Editing a step
+
+Tap to toggle a step in the **edited bank and selected voice only**. Deleting a step
+also deletes its accent. Hold for 400 ms to toggle accent once; this also creates the
+step if it was empty. Releasing after a hold does not undo the result.
+
+Unaccented sequencer hits use velocity 0.72. Accents use 1.0. This is a two-level
+dynamic system, not a full per-step velocity editor. MIDI hits can use all 127 nonzero
+velocity values. Velocity zero does not trigger a voice.
+
+### A and B
+
+A and B are separate sixteen-step banks containing all four tracks. They share the
+four current voice settings, tempo, swing, drive and mutes. Changing Tune on A also
+changes that voice when B plays. They are pattern variations, not independent kits.
+
+Selecting A or B immediately changes the editing bank. While running, the playback
+change occurs at the next bar's step 1. While stopped, bank selection takes effect
+immediately. Stop and Start restart the sequence at step 1 rather than continuing
+from the old position.
+
+There is no automatic A-to-B copy command in this candidate. Build a different bank
+manually or start from a tutorial containing both variations.
+
+### Fill
+
+Fill is a third bank. Key 7 in Shift selects it for editing, without switching the
+underlying A/B arrangement. Hold Shift + key 8 to borrow the Fill bank for each
+new step. The underlying sixteen-step phase continues. On release, the next step
+uses the active A/B bank at that same phase.
+
+This is **not** an automatic one-bar fill, a retrigger roll, or a parameter-lock system.
+Pressing Fill between steps does not immediately strike a drum. A short hold that
+contains no step boundary may produce no Fill hit. An A/B request still commits at
+the next bar boundary even while Fill is held.
+
+### Swing and tempo
+
+Swing delays every second sixteenth within a two-step pair while preserving the pair's
+nominal length. At 50% the steps are straight. At 70%, the first interval occupies
+70% of the pair and the second 30%. Swing changes commit at a pair boundary;
+tempo changes preserve the accumulated musical phase instead of restarting the clock.
+
+Sequencer timing is sample-domain timing relative to the device audio clock.
+It is not evidence that the physical oscillator has zero ppm error or that two
+unconnected instruments stay synchronized forever.
+
+## 5. The voices
+
+All four voices are synthesized. There are no samples to manage or load.
+
+| Voice | Tune range | Amplitude T60 range | Character |
+|---|---|---|---|
+| Hammer | 32–110 Hz | 60 ms–1.4 s | Strength of pitch punch and second harmonic |
+| Crack | 120–330 Hz | 40–800 ms | Body/noise balance and noise brightness |
+| Steel | 700–2300 Hz | 20–300 ms | Inharmonic metal/noise balance and brightness |
+| Arc | 55–900 Hz | 50 ms–2.4 s | Modulator ratio and phase-modulation depth |
+
+T60 means the exponential decay takes that duration to reach approximately 0.001 of
+its starting amplitude, or −60 dB in amplitude ratio. It does not mean the entire
+sound is cut off at that instant. The envelope reaches a very small tail threshold
+before it is set to exact zero.
+
+### Hammer: body and impact
+
+Hammer combines a sine body with a small second harmonic. A short pitch envelope
+gives the beginning of the hit more impact. Tune moves the body pitch; Decay controls
+the amplitude tail; Character increases the transient pitch excursion and harmonic bite.
+
+Start with low Drive. Raise Character while holding Tune steady, then shorten Decay.
+The impact should become more pronounced without turning the basic kick into a
+permanent oscillator. High Character is an exaggerated synthesized kick, not a
+model of a particular commercial drum circuit.
+
+### Crack: shell and snare noise
+
+Two inharmonic sine components form the body. High-pass-shaped deterministic noise
+provides the snare-like component. Low Character favors the pitched body; higher
+Character adds a brighter, noisier crack. There is no high-Q resonator that can enter
+self-oscillation.
+
+Audition Crack while stopped. Change Tune first to hear the body. Then change Character
+to find the point where the noise supplies enough edge. Avoid compensating a quiet
+Level by immediately maximizing global Drive; learn the voice's own balance first.
+
+### Steel: metallic rhythm
+
+Six bounded sine oscillators are combined in three pairs to create an inharmonic
+metallic spectrum, mixed with shaped noise. Short Decay gives a closed-hat role;
+longer Decay makes the metallic body easier to hear. This is one voice, with no
+separate open-hat lane or choke group.
+
+Try alternating steps, then accent every fourth hit. Increase swing before adding
+more notes. The tutorial exercises intentionally show that timing and dynamics can
+change the feel without requiring a denser pattern.
+
+### Arc: FM-style percussion
+
+Arc uses feed-forward sine phase modulation, a close relative of sinusoidal FM
+synthesis, with a moving modulation envelope. Character changes the modulator ratio
+and depth. Low values can be rounded or bell-like; larger values are more metallic.
+
+The carrier phase does not reset on a retrigger, and the modulation-envelope level
+ramps from its current state rather than jumping. That reduces one specific
+retrigger-click mechanism. It does not mean every extreme FM setting is spectrally
+clean. High-pitch/high-Character settings can alias; the candidate does not claim
+oversampled or alias-free synthesis.
+
+## 6. Drive, level and stopping
+
+Voice Level, mute gain, Drive and Master have different jobs. Level balances a drum;
+mute temporarily removes it; Drive increases gain before the bounded saturator;
+Master controls the final mix.
+
+The path includes a 10-Hz DC blocker and a bounded rational saturator. With valid
+internal state and Master no higher than 1, the final normalized samples are bounded
+below approximately ±0.736. That arithmetic is about digital samples, not volts at
+a jack, acoustic loudness or calibrated headroom.
+
+Mute, Stop and Panic use short gain/envelope transitions. The oscillator and envelope
+state is not abruptly zeroed while audible. A residual DC-filter tail may remain
+briefly after the voice release; tests check return to silence. Normal percussion,
+especially noise and high-frequency metallic voices, naturally has large adjacent
+sample differences. The transition test compares matched signals with and without
+a control event rather than treating every steep drum transient as a defect.
+
+There is no feedback delay, reverb freeze or resonant filter in this candidate.
+Unintended endless oscillation is not a musical feature. If a sound continues when
+it should stop, lower the external listening level, use Panic and save the telemetry
+and reproduction steps for investigation.
+
+## 7. Tutorial presets
+
+Tutorials are compiled original data, not extracted factory patterns. They load a
+complete set of three banks, four voice settings, tempo, swing and drive. Loading
+resets mutes and stops transport. **Master is retained** so a tutorial cannot silently
+replace your chosen listening level.
+
+To load: stop with SW1, hold SW2, tap key 14 or 15 to choose a tutorial, read its name,
+then tap key 16. Release SW2. The audio path fades down for about 5 ms, applies the
+new data at zero gain and ramps up again. Controls re-arm pickup. Selection is a
+preview until confirmed; the preview expires after five seconds.
+
+Loading a tutorial or clearing a track discards the affected unsaved edits.
+There is **no user-save function, undo or persistence across power cycles** yet.
+Write important edits in the patch notes sheet before loading something else.
+
+| Tutorial | Main lesson |
+|---|---|
+| Blank Canvas | Build the first sixteen-step pattern without hidden content |
+| First Pulse | Kick Tune, Decay and Character |
+| Backbeat | Balancing three complementary drum roles |
+| Broken Grid | Syncopation and A/B variation |
+| Alloy Swing | Metallic hats, accents and swing |
+| Arc Study | Tuned modulation-based percussion |
+| Night Shift | Four-voice balance and controlled drive |
+| Fracture Lab | Fill, mutes and more aggressive performance |
+
+[Preset lessons](PRESETS.md) contain the exact values, banks and step grids.
+The companion host WAVs demonstrate the programmed scenario, not recorded Field audio.
+
+## 8. MIDI and external connections
+
+Beat receives serial MIDI through the Field's initialized `MidiUartHandler`.
+It does not configure USB MIDI. Connect a known-good source through the board's
+documented MIDI input connection and verify it in Field Truth first.
+
+| Message | Response |
+|---|---|
+| Channel 10 Note On 36 | Hammer |
+| Channel 10 Note On 38 | Crack |
+| Channel 10 Note On 42 | Steel |
+| Channel 10 Note On 39 | Arc |
+| Nonzero note velocity | Trigger level |
+| Note On velocity 0 / Note Off | No new trigger; voices are one-shots |
+| MIDI Start | Start from step 1 when stopped; ignored when already running |
+| MIDI Stop / System Reset | Priority stop/panic and discard queued old commands |
+| Channel 10 CC 120 / 123 | Priority panic |
+| MIDI Clock / Continue | Ignored; not an external-clock follower |
+
+Do not expect a DAW or Hydrasynth clock to synchronize Beat just because MIDI Start
+works. There is no MIDI clock PLL, song-position handling or clock arbitration in this
+candidate. The fixed queue rejects excess ordinary commands and reports drops.
+Priority stop is separate from that queue.
+
+Beat ignores both audio inputs and leaves CV/Gate outputs commanded off. Its CV
+inputs and Gate In do not modulate or clock the instrument. Field Truth exercises
+these interfaces, but future musical integration requires measured mappings and
+an explicit control/clock specification.
+
+## 9. Field Truth bench program
+
+Field Truth is not a sound preset inside Beat. It is a separate diagnostic firmware.
+Its stereo callback passes input to output at unity digital gain. Start with a
+low-level calibrated source and disconnected CV/Gate cables. It is intentionally
+not limited, so that gain/clipping tests measure the actual path.
+
+Raw key press/release records use indices 0–15. Hold and release every physical key,
+record its label and LED correspondence, and compare the complete set. Knob and CV
+telemetry are normalized readings multiplied by 10,000. They are **not millivolts**.
+
+The output test is off until SW1 has first been observed released. After that,
+holding SW1 alone enables the test. Knobs 1 and 2 independently select DAC codes
+0, 1024, 2048, 3072 or 4095 in five zones; Gate Out is commanded active.
+Release SW1 to command zero/off. SW2 inhibits this output test.
+
+This is a software interlock, not a fail-safe circuit. A crashed program can leave
+an output asserted. Use an isolated bench fixture appropriate to the board and
+do not connect this output test to equipment with unverified input limits.
+Debounced switch handling also means release is not electrically instantaneous.
+
+Holding SW2 alone runs the BSP LED/OLED light test. MIDI reception is counted and
+the latest message metadata is reported. Gate In is sampled at the callback rate;
+narrow pulses can be missed. Timing is exposed through the Seed testpoint and
+callback counters. Check probe access and electrical loading before attaching
+a scope or logic analyzer to an assembled Field.
+
+The periodic `boot` record replays build/rate/board/memory/loader information.
+`reset=unknown` is deliberate. Receiving this line after USB enumeration does not
+prove a true cold boot, the reset source or absence of an earlier fault.
+
+## 10. Troubleshooting
+
+**No sound:** confirm which image is running. Truth needs an audio input. Beat needs
+an audition, supported MIDI hit or active steps plus Play. Check Master pickup,
+voice Level, mutes, edited versus playing bank, mixer connection and actual key mapping.
+
+**Knob appears stuck:** it probably has not picked up the stored target. Read the
+parameter percentage and sweep slowly through it. Preset loading and voice selection
+intentionally re-arm pickup.
+
+**Step changed differently from expected:** short release toggles the step; a
+400-ms hold changes accent. A Shift gesture is consumed even if Shift is released first.
+
+**Changing bank did not sound immediate:** A/B playback changes at the next bar.
+Editing changes immediately. Fill is borrowed per step, not a restart.
+
+**Preset controls do nothing:** Stop first. Key 14/15 preview; key 16 confirms.
+The program deliberately refuses a running load.
+
+**MIDI runs but drifts against another box:** external clock following is absent.
+Start/Stop handling does not establish tempo synchronization.
+
+**A click, dropout or runaway sound:** lower external volume, Panic, capture the build
+manifest, raw log, control sequence and audio recording. Inspect `over`, `late`, drops,
+faults and callback waveform. Do not diagnose solely from a successful host test.
+
+## 11. Patch notes
+
+Before discarding edits, record: tutorial, tempo, swing, drive, master, four normalized
+voice parameter sets, A/B/Fill note and accent grids, and mute state. Also record the
+binary hash and verified physical key mapping. A printed grid is a temporary backup
+method, not a claim that the firmware implements storage.
+
+## 12. Instructional sources
+
+The supplied Hydrasynth Explorer manual's Home/shortcut/macro explanations
+(pp. 14–18, 24, 66–67) informed direct access and clear distinctions between selection
+and action. Its cover says Version 2.0 despite the attachment's 2.2.0 filename.
+The supplied DFAM manual's signal-flow overview and progressive listening tour
+(pp. 7–12), envelope explanation (pp. 20–21) and trigger/advance distinction
+(pp. 22–23) informed the teaching order.
+
+HydraPulse's controls, algorithms, presets, words and diagrams are its own candidate
+design. It is not a Hydrasynth or DFAM emulation, and neither source manual is bundled.

+These are fourteen distinct CTest executables, repeated across four build
+configurations; do not describe them as fifty-six distinct behavioral tests.
+The source history also includes ordinary four-test R0 results. Those historical
+results are not being substituted for this candidate's validation.
+
+## Repaired audible-transition failure
+
+The first matched-trajectory test failed on an active Arc retrigger:
+**1.42942 full-scale first-sample deviation** versus its untouched reference.
+After replacing the modulation-depth reset with a 1 ms rise from current state,
+the worst tested retrigger deviation is **0.0320582**.
+
+Smoothing the noise-filter coefficient reduced the tested parameter-event
+deviation from **0.210695** to **0.0263815**. `test_transitions` also verifies
+that repeated Stop/Release does not postpone silence.
+
+The before/after logs are retained. These are selected software regression
+measurements, not an assertion that every audible click or aliasing mechanism
+has been eliminated.
+
+## Host audio measurements
+
+Eight original tutorials were rendered twice using the actual C++ Engine.
+All WAVs are 48 kHz, stereo, 16-bit PCM, ten seconds long. Bank B is requested
+at 3 s, Fill held from 5 to 6 s, Panic at 7 s.
+
+Observed maximum peak over the scenarios: **0.300022 normalized**.
+All scenario fault counters are zero. All final-second PCM tails are exactly
+silent. Blank Canvas is intentionally silent. The metrics file records peak,
+RMS, DC, maximum adjacent-sample delta and tail level.
+
+The renderer is not Field audio capture. A high noisy-drum adjacent-sample
+delta is not itself evidence of a control click. No listening assessment,
+alias-free claim, physical SNR result, analog-voltage result or host/target
+numerical equivalence is inferred.
+
+## Local holds and unexecuted checks
+
+**Earlier GCC ASan route: HOLD.** Its binaries built, but the runtime rejected
+startup because the ASan library was not first in the library list. That run
+is not counted as PASS. The separately compiled Clang ASan+UBSan suite
+subsequently passed all fourteen tests in the unchanged host environment.
+The failure log remains visible rather than being erased.
+
+**Real ARM build: NOT_RUN.** Running `tools/build_target.py` exited nonzero at
+preflight because the `arm-none-eabi-*` tools are absent. The real dependency
+verifier separately rejected the missing local libDaisy checkout. No real
+target compiler or linker was executed. No firmware BIN/ELF/MAP is supplied.
+
+**Pinned libDaisy checkout: NOT_VERIFIED in this runtime.** Full commit and
+license-blob identities came from earlier repository inspection in this
+conversation. Current public API/build sources were inspected, but this does
+not replace compiling the exact pin. The private-checkout verifier and build
+script make that a hard Codex gate.
+
+**Mermaid parser/rendering: NOT_RUN.** Eight `.mmd`/Markdown pairs are checked
+for exact source consistency and were reviewed against the implementation.
+The actual CLI is absent. Do not label pair consistency as grammar/render PASS.
+
+**Formatter: NOT_RUN.** No clang-format executable was available. C++ warnings
+are treated as errors by the host build; that is not a formatting check.
+
+**GitHub publication and CI: NOT_RUN.** No remote changes were made. The live
+target fork, its current master HEAD and any extra private tools were not
+qualified through this run's public retrieval route. The old dedicated
+repository's historical CI result does not apply to this candidate.
+
+**Physical P0/P1: NOT_RUN.** No Field was attached. Key/LED physical mapping,
+boot/reset provenance, audio, CV/Gate levels, MIDI electrical reception and
+callback margin remain bench measurements. The candidate's output-arm logic
+is not hardware fail-safe protection.
+
+**DVPE: intentionally omitted.** No valid graph/schema/export round trip was
+executed. No guessed `.dvpe` or new DVPE registry block is delivered.
+
+## Evidence files and next gate
+
+Raw commands/output and tool versions are in `evidence/local`. Machine-readable
+results bind the runtime source list; the package manifest binds delivery bytes.
+The printable manual is a separate artifact generated from the active Markdown,
+not a copy of either supplied commercial manual.
+
+Use `CODEX_EXECUTION.md` for actual repository comparison, additive integration,
+exact dependency checkout, target compilation, Mermaid rendering, CI and
+non-destructive publication. Use `QA_PLAN.md` and the eleven NOT_RUN hardware
+record templates for the subsequent bench work.
+
+All review in this authoring context is non-independent. No formal release
+or independent assurance is claimed.

+# Context
+
+The instrument and diagnostic are different firmware images. Beat ignores audio inputs and keeps
+both DAC codes and Gate Out at zero/false. Truth provides the measurement path.
+No MIDI parser, display writer or logger has a reference to Engine in a concurrent context:
+the foreground sends value-only commands, and receives value-only snapshots.
+The single audio owner is the primary race-avoidance mechanism. The two SPSC queues have
+one producer and one consumer each, reject overflow and never overwrite unread slots.
+Source: firmware/HydraPulse.cpp, firmware/FieldTruth.cpp, src/app/Engine.*.

+# Firmware Ownership
+
+Expected firmware sample rate is 48,000 Hz, block length is 48 frames and scan rate is 1,000 Hz.
+These are configuration values, not measured physical clock accuracy. A snapshot is offered
+every 40 callbacks (25 Hz). The foreground consumes at most eight per iteration and displays
+only the last. Normal MIDI command consumption is at most eight per callback; urgent stop
+does not wait behind note traffic.
+CpuLoadMeter brackets callback work and uses System ticks, not Cortex cycle counts.
+The testpoint pulse includes the user callback body but excludes library interrupt entry,
+sample conversion outside the callback and exit overhead. Late-start and overrun counters
+are indicators, not a complete DMA underrun detector. Measure the instrumented interval
+and interrupt/codec behavior on the actual hardware before interpreting headroom.

+# Synthesis
+
+All four algorithms are original in this package, not ports of the manuals or unverified community DSP.
+The shared 1,025-entry sine table is initialized once before audio starts. Noise is xorshift32
+with per-voice deterministic seeds. No audio processing requests random bytes from a peripheral.
+Hammer uses a unipolar exponentially decaying pitch transient; Character scales its amount.
+Crack blends two sine modes with high-passed noise. Steel sums three products of six sine
+partials and adds shaped noise. Arc uses feed-forward phase modulation; its Character changes
+modulator ratio and index, not a feedback gain.
+
+The attack is 1 ms for Hammer/Crack/Arc and 0.5 ms for Steel. Decay is a T60-like parameter:
+coefficient = exp(-ln(1000)/(Fs*T60)). Release is a 5 ms linear ramp from the current envelope
+value to exact zero. Retrigger starts from the current amplitude and retains oscillator phase.
+The pitch/modulation transient has its own 1 ms attack from current state, avoiding an
+instantaneous phase-modulation jump on Arc retrigger. Frequency, Character, Level and the
+noise-filter coefficient use 5 ms ramps; changing a decay coefficient changes slope,
+not the current envelope value. The noise-filter coefficient is bounded between zero and one.
+The master is capped by the mathematical output path; this is not a true-peak/lookahead limiter.
+Harmonics from phase modulation, ring products and saturation still require aliasing/listening QA.
+No resonant filter or delay feedback loop is present in this candidate.

+# Clock Transport
+
+The step grid is always 16 steps. Internally indices are 0..15; the manual labels them 1..16.
+At Start, step zero emits on the next processed sample, then GrooveClock counts subsequent
+samples. At 120 BPM without swing, a boundary occurs every 6,000 samples at 48 kHz.
+For normalized swing w in [0,1], s = round(400*w). Phase increment is BPM_micro * 4 * 1000.
+Long threshold is Fs*60*1,000,000*(1000+s); short threshold substitutes (1000-s).
+Thus each constant-tempo swing pair retains exactly two nominal step durations before
+sample quantization. Remainder is retained, so error against the quantized-BPM rational
+reference stays below one sample. The display reports 50..70 percent swing.
+This is a sample-domain property, not a claim about crystal tolerance or MIDI jitter.
+
+An A/B request changes the edit bank immediately, and changes the playback bank at the
+next step-zero boundary. A request while stopped sets the bank immediately.
+Fill substitutes its pattern at the next step boundary while held and leaves transport
+phase/step number unchanged. Release returns to the active A/B bank at the next boundary.
+It is not an automatic one-bar Fill latch. Stop releases sounds; Start restarts the grid.
+Incoming MIDI TimingClock and Continue are intentionally ignored, not partly implemented.

+# Controls Menu
+
+There is no menu stack, machine browser, patch hierarchy or desktop editor requirement.
+The Shift palette is a temporary action legend. Preset preview is a five-second pending
+selection shown on Home, not a browsing page; it never changes sound until confirmed.
+SW1 is a tap-release transport action. Holding both switches cancels any pending transport
+tap, so releasing the panic chord cannot accidentally restart playback.
+
+Knob mapping: 1 Tune, 2 Decay, 3 Character, 4 Level, 5 Tempo (40..240 BPM),
+6 Swing (50..70 percent), 7 Drive, 8 Master. All use pickup; sound pickups re-arm on
+voice selection, all pickups re-arm after preset load. A pickup bit of one means not captured.
+Knob values and target values shown in the manual are normalized percentages, not voltages.
+
+Shift+13 must be held for one second while stopped to clear the selected track in the edit bank.
+Preset load and clear are unavailable during playback. Ordinary taps toggle, rather than
+cycling through velocity states. Long step hold toggles its accent and ensures the step exists.
+Keys consumed by Shift cannot become ordinary step edits when the modifier is released first.
+Physical labels remain provisional until P0 validates FieldAdapter.h mapping on the actual unit.

+Preset preview/loading are independent flags, not persistent menu pages. Releasing SW2
+returns the display to Home even if a preview is still pending; loading while SW2 is held
+does not force the palette closed. The next control tick re-arms pickup after the engine revision changes.

+The inspected upstream daisy_field.cpp uses the Field BSP, not an invented per-pin HAL.
+Its Rev2 constants associate Gate In with Seed D0, Gate Out with D15, pot mux ADC with D16,
+CV inputs with D17/D18/D25/D24, DAC outputs with D23/D22, the two switches with D30/D29,
+and the keyboard shift-register signals with D26/D27/D28. These are source observations,
+not a substitute for the schematic and board-revision check. Do not wire directly to those
+pins from this document. Use the stock Field connectors and qualified fixture.
+
+The inspected Seed implementation maps the testpoint to PG14 and the Seed LED to PC7.
+Testpoint accessibility and probe grounding on the assembled Field are not verified.
+CV inputs are reported in BSP normalized bipolar units; do not interpret 10,000 telemetry
+units as a fixed number of volts without calibration. DAC codes are 0,1024,2048,3072,4095.
+Voltage, polarity, loading, limits and ground reference remain bench-measured fields.
+Gate sampling at 1 kHz cannot prove detection of shorter-than-scan pulses.
+The musical image holds CV/Gate outputs off and has no external audio-through lane.
+Sources: source ledger entries DAISY-FIELD, DAISY-SEED and DAISY-SYSTEM.

+# Preset Transaction
+
+Presets are generated from presets/tutorials.json by tools/generate_presets.py.
+The JSON is the editable source; the checked-in C++ table is a build asset whose exact
+content is checked. There are eight presets with three banks and four voices each.
+The preset contains rhythm masks, accents, sound parameters, BPM, swing and drive.
+It does not contain master volume, which remains under the user's control.
+
+There is no persistent save in this version. Edits live in RAM and are lost at power-down,
+reset or confirmed preset load. No blank "save" menu implies otherwise.
+The renderer exercises A/B, Fill and panic within each tutorial's ten-second host scenario.
+Later storage requires a versioned schema, CRC, bounds checks, two-slot atomic commit,
+power-interruption tests and a non-audio owner for flash operations.

+# Verification
+
+A PASS belongs to a specific executed test on a specific artifact. Host tests cover software
+contracts, not ARM timing, codec gain, analog voltage or instrument ergonomics. The contract
+stub compiles source against locally declared API shapes and must never be reported as
+libDaisy or ARM validation. The target script refuses to substitute a native compiler.
+
+Hardware records use VERIFIED, DERIVED, PROPOSED, ASSUMED, HOLD or NOT_RUN.
+A VERIFIED hardware row requires fixture identity, firmware hash, raw artifact paths and
+measurement method. Simulated waveforms cannot occupy measured-hardware fields.
+Public CI never runs DFU/OpenOCD/programming commands. Missing toolchain or missing
+physical hardware holds those gates without erasing completed source work.

+# HydraPulse Field
+
+HydraPulse Field is a staged, standalone drum/performance instrument for the stock Electro-Smith Daisy Field.
+
+The project is deliberately proving the instrument in layers instead of implementing the whole product at once. The first musical target is an independent Field drum machine. Hydrasynth-specific MIDI/CV/audio interaction is deferred until the standalone foundation is credible.
+
+## Scope
+
+### Product direction
+
+- Stock Daisy Field is the first hardware target.
+- Normal interaction stays centered on 16 visible steps.
+- Beginner invariant: **select drum -> tap 16 steps -> edit sound -> Play**.
+- Common voice language: **Tune | Decay | Character | Level**.
+- First four synthesized voices: **Hammer** (kick), **Crack** (snare), **Steel** (closed hat / metallic), **Arc** (FM percussion).
+- A/B/Fill precedes deep trig-lock, probability, ratchet, and microtiming systems.
+- Hydrasynth integration is intentionally deferred.
+
+### What this bootstrap implements
+
+This repository bootstrap is the pre-hardware software foundation, called **R0** so it is not confused with P0 hardware truth.
+
+Implemented now:
+
+- hardware-independent C++17 core;
+- 16-step pattern container;
+- deterministic step sequencer;
+- sample-domain integer timing clock;
+- soft-takeover / pickup primitive;
+- native CMake + CTest harness;
+- deterministic stress and long-run timing tests;
+- repository/provenance validators;
+- GitHub CI for native tests and ASan+UBSan;
+- pinned upstream provenance records;
+- P0 Field Truth implementation contract and evidence layout.
+
+Not implemented yet:
+
+- Daisy Field firmware binary;
+- ARM cross-build verification;
+- any physical Daisy Field measurement;
+- audio/CV/Gate/MIDI hardware evidence;
+- P1 drum synthesis;
+- A/B/Fill;
+- advanced sequencing;
+- Hydrasynth integration.
+
+A compile is not hardware evidence, and a host test is not ARM timing evidence. This repository treats those as different claims on purpose.
+

+cmake --build build-sanitize --parallel
+ctest --test-dir build-sanitize --output-on-failure
+```
+
+## Milestones
+
+- **R0 - Repository foundation:** deterministic host core and automation. Implemented in this bootstrap.
+- **P0 - Field Truth Test:** actual stock Field controls, audio, CV/Gate, MIDI, display/LED behavior, and callback timing measured on hardware.
+- **P1 - Beat Core:** Hammer / Crack / Steel / Arc with deterministic sonic scenarios.
+- **P2 - Performance layer:** A/B/Fill and direct live gestures.

+
+## Upstream boundaries
+
+R0 does not vendor libDaisy or DaisySP. Exact upstream commits inspected for this bootstrap are recorded in `deps.lock.json` and `third_party/manifest.json`.
+
+The source review also records useful architecture/test references found through `Denys/embedded-audio-mine`. Those references are evidence and design inputs, not proof that their implementation belongs in HydraPulse.
+
+## Root license
+
+No HydraPulse root license is selected in this bootstrap. That decision remains explicit rather than being silently inferred from dependencies or references.

+# Architecture
+
+## Design rule
+
+HydraPulse keeps musical timing and pattern semantics independent of libDaisy wherever practical. Hardware code adapts real Field I/O into stable core-facing values; it does not own sequencer semantics.
+

+
+## R0 core
+
+### `Pattern16<Tracks>`
+
+Fixed-size, allocation-free 16-step bit patterns. Bounds failures are explicit boolean results rather than exceptions. The structure is intentionally boring because musical pattern state should not depend on heap behavior.
+
+### `StepSequencer<Tracks>`
+
+Deterministic transport-to-pattern bridge. `Start()` restarts at step zero. Each `EmitAndAdvance()` returns a fixed-size tick containing the step index and track bitmask. Trigger enumeration is always ascending track order.
+
+### `SampleAccurateStepClock`
+
+Integer phase accumulator. BPM is quantized to one micro-BPM and accumulated in sample domain. This avoids cumulative floating-point drift and naturally alternates adjacent integer sample intervals when the exact interval is fractional.
+
+The clock only defines boundaries. It does not decide whether Start should emit step zero immediately; that policy belongs to the transport/sequencer integration.
+
+### `ControlPickup`
+
+Normalized `[0,1]` soft takeover. A physical control remains disconnected until it reaches or crosses the stored target, then tracks directly.
+
+## P0 Field adapter contract
+
+The P0 adapter must prove, not assume:
+
+- physical order of all 16 key scan indices;
+- eight knob endpoints and monotonic direction;
+- four CV input usable ranges;
+- Gate In polarity/threshold behavior at the assembled Field;
+- Gate Out electrical levels;
+- both CV output transfer functions;
+- MIDI receive path;
+- stereo audio path and real gain/headroom/noise/crosstalk;
+- OLED and LED behavior;
+- callback period, execution distribution, worst observed execution, and margin.
+
+The official `DaisyField` API inspected for R0 exposes `KNOB_1..8`, `CV_1..4`, keyboard state/edge methods, `gate_in`, `gate_out`, `midi`, OLED display, LED driver, and `SetCvOut1/2()`.
+
+## Real-time boundary
+
+The audio callback may perform bounded DSP, state snapshots, and constant-time instrumentation. It must not perform serial logging, OLED writes, storage access, dynamic allocation, or unbounded work.
+
+Human-readable telemetry is emitted outside the callback from data captured by bounded instrumentation.
+
+## Future portability
+
+If the concept proves worthwhile, the pure core and stable voice interfaces become the portable layer. The first product should not pay the abstraction tax of a hypothetical future hardware platform before the Field instrument itself is useful.

+## Native tests executed
+
+- `test_pattern16`
+- `test_step_sequencer`
+- `test_sample_clock`

+
+The pattern test includes a deterministic 20,000-operation state stress sequence. The sample-clock test checks 1,024 non-integer-BPM step events against ideal sample-domain timing and requires each event to remain within one sample.
+
+## Scope of claim
+
+These results verify the generated R0 host core and repository automation in this runtime. They do not verify ARM behavior, libDaisy integration, callback timing on STM32H7, or any analog/electrical/audio performance of Daisy Field.

+# Staged proof-of-concept sequence
+
+HydraPulse uses completion gates that separate software plausibility from physical truth.
+
+## R0 - Repository foundation
+
+**Goal:** create a deterministic, hardware-independent base that can be tested on every commit.
+
+Implemented in this bootstrap:
+
+- fixed-size 16-step pattern state;
+- deterministic sequencer;
+- sample-domain tempo clock;
+- soft takeover;
+- host tests and deterministic stress tests;
+- repository/provenance validation;
+- ASan+UBSan CI definition.
+
+**Gate:** native build + CTest + validators pass. Sanitizer CI is defined but is not considered executed until GitHub runs it.
+
+## P0 - Field Truth Test
+
+P0 is a hardware characterization milestone, not a feature demo.
+
+### P0.1 Build truth
+
+- add `firmware/field_truth/FieldTruth.cpp` and project-local build metadata;
+- pin and fetch libDaisy;
+- build libDaisy;
+- build Field Truth for ARM;
+- preserve exact build log and firmware hash.
+
+**Gate:** ARM build passes. This does **not** complete P0.
+
+### P0.2 Control truth
+
+Measure and record:
+
+- all 16 raw keyboard scan indices versus physical keys;
+- eight knob raw/min/max and direction;
+- four CV input raw/min/max across known applied voltages;
+- Gate In low/high behavior and edge detection;
+- MIDI receive event types and raw values;
+- OLED/LED basic functionality.
+
+### P0.3 Output truth
+
+Measure:
+
+- CV Out 1 and 2 voltage versus requested code;
+- Gate Out low/high voltage;
+- output safety behavior during boot/reset.
+
+### P0.4 Audio truth
+
+With a documented source/load/measurement fixture:
+
+- stereo passthrough gain;
+- frequency response sufficient to expose gross path errors;
+- clipping/headroom;
+- noise floor under a defined bandwidth/method;
+- channel crosstalk;
+- cold-boot behavior.
+
+### P0.5 Callback truth
+
+Instrument full callback entry-to-exit time. Record:
+
+- sample rate;
+- block size;
+- callback period;
+- min/mean/p99/p99.9/max or the closest feasible distribution summary;
+- overrun/deadline count;
+- test duration and load condition;
+- probe point / GPIO method if external timing is used.
+
+**P0 completion gate:** physical evidence exists for controls, audio, CV/Gate, MIDI, and callback timing. Compilation alone cannot satisfy P0.
+
+## P1 - Beat Core
+
+Only after P0:
+
+1. Add stable voice interface.
+2. Implement Hammer / Crack / Steel / Arc.
+3. Keep Tune / Decay / Character / Level semantics common.
+4. Drive voices from the R0 sequencer/clock.
+5. Add deterministic sonic scenarios on host where practical.
+6. Compare host numerical behavior with target captures where practical.
+7. Add audio loopback evidence on Field.
+
+**P1 completion gate:** four voices sequence reliably on Field, deterministic regressions pass, and real target audio/timing evidence shows credible margin.
+
+## P2 - A/B/Fill
+
+Add direct performance variation before deeper sequencing. Preserve the 16-step surface.
+
+## P3 - Advanced sequencing
+
+Add only when direct operation remains coherent:
+
+- microtiming;
+- ratchets/retrigs;
+- probability/conditions;
+- parameter locks.
+
+## P4 - Hydrasynth interaction
+
+Deferred until standalone proof:
+
+- MIDI clock/control;
+- analog Pitch/Gate/Mod interaction;
+- clock jitter/drift comparison;
+- optional stereo audio-through;
+- ducking / rhythmic destruction.

+# Source review used for R0 bootstrap
+
+Date: 2026-08-16
+
+This review records sources actually inspected before creating the bootstrap. `Denys/embedded-audio-mine` was used as a discovery index; upstream repositories were then inspected directly for concrete files/APIs.
+
+## Repository state
+
+### `Denys/HydraPulse-Field`
+
+- configured default branch: `main`;
+- repository visibility observed through the connected GitHub app: private;
+- GitHub contents API returned: **repository is empty**;
+- no branch ref / HEAD commit exists yet, so there is no main SHA to preserve.
+
+### `Denys/embedded-audio-mine`
+
+Inspected commit:
+
+`1113f0c6255c24a6655be968fb5aa115b8d5f7e9`
+
+Its README explicitly separates published digests, selected projects, and anti-repeat evidence. A selected project is not automatically a reusable dependency. That distinction is retained here.
+
+## Official Daisy sources
+
+### `electro-smith/libDaisy`
+
+Inspected commit:
+
+`cc146d5065dd8286078a662e2830bf820c37a612`
+
+Verified public Field API in `src/daisy_field.h` includes:
+
+- eight `KNOB_*` entries;
+- four `CV_*` entries;
+- 16-key keyboard state/rising/falling edge functions;
+- `SetCvOut1()` and `SetCvOut2()`;
+- `gate_in` and `gate_out`;
+- `midi`;
+- `display`;
+- Field LED driver;
+- audio/ADC lifecycle methods.
+
+`src/daisy_seed.h` also exposes `SetLed()`, `SetTestPoint()`, `StartLog()`, `Print()` and `PrintLine()`.
+
+`src/hid/gatein.h` exposes both edge-style `Trig()` and current `State()`.
+
+### `electro-smith/DaisyExamples`
+
+Inspected commit:
+
+`259ed82c7d4c0d7699f695945e6e111b7dc7cb27`
+
+Verified examples:
+
+- `field/KeyboardTest/KeyboardTest.cpp` uses `DaisyField`, 16 keyboard states, eight knobs, four CV inputs, LED driver and DAC output;
+- `field/Midi/Midi.cpp` uses `hw.midi.StartReceive()`, `Listen()`, `HasEvents()` and `PopEvent()`;
+- `field/KeyboardTest/Makefile` shows the conventional libDaisy/DaisySP relative layout and core Makefile include.
+
+These are the preferred starting references for P0 because they exercise the actual target BSP.
+
+### `electro-smith/DaisySP`
+
+Inspected commit:
+
+`599511b740f8f3a9b8db72a0642aa45b8a23c3a3`
+
+Reserved for P1. R0 does not depend on DaisySP.
+
+## Embedded Audio Mine leads reverified upstream
+
+### `bkshepherd/DaisySeedProjects`
+
+Inspected commit:
+
+`80feee11f26a401ae324de75d9266e63ed82deb2`
+
+Verified `BaseHardwareModule` API includes audio lifecycle, control processing, hardware capability queries, MIDI/display members, and protected initialization helpers. `GuitarPedal125B` derives from that base and overrides `Init()`.
+
+**Borrowed idea:** keep hardware-facing details behind a stable adapter rather than allowing application semantics to spread through BSP calls.
+
+### `hasanalpdoyduk/Teensy_Drum_Machine`
+
+Inspected commit:
+
+`187393d087a406134deee944edcd400aad7c7367`
+
+Verified repository tree contains separate `ClockEngine`, `InstrumentManager`, `StorageManager`, `MidiEngine`, input managers and `Sequencer`. `Firmware/Sequencer.h` exposes direct `toggleStep`, `setStep`, `advanceStep`, `resetStep`, and selected-instrument state around a fixed pattern array.
+
+**Borrowed idea:** direct 16-step semantics plus clear subsystem boundaries. HydraPulse core code was written independently for a fixed-size, libDaisy-free host-testable implementation.
+
+### `kencul/STM32F4-AudioSynthesis`
+
+Inspected commit:
+
+`b1de88d6a3967327cc8a0eeccba1ebad524ccbd2`
+
+Verified `.github/workflows/tests.yml` configures/builds/runs `tests` with CMake/CTest. `tests/CMakeLists.txt` explicitly compiles hardware-independent DSP sources on host while excluding HAL/hardware dependencies. The target application also uses Cortex DWT cycle-counter instrumentation.
+
+**Borrowed idea:** host CMake/CTest for pure DSP/core plus separate target timing instrumentation.
+
+## Not imported into R0
+
+No community project source file is copied wholesale into the R0 core. The source ledger preserves exact upstream commits and the architectural concepts used.
+
+License constraints were explicitly disabled by the user for this bootstrap turn; provenance was still retained so later release policy can be re-enabled without reconstructing history.

+
+## Evidence layers
+
+HydraPulse does not collapse unlike tests into one green badge.
+
+| Layer | What it proves | What it does not prove |
+|---|---|---|
+| Host unit tests | deterministic core semantics | ARM timing, Field I/O, audio quality |
+| Deterministic stress tests | repeatable invariants under many operations | true fuzz coverage or target behavior |
+| ASan/UBSan | common host memory/UB failures | embedded memory map correctness |
+| ARM build | toolchain/API/build integration | electrical behavior or real-time margin |
+| Target instrumentation | execution on MCU | analog audio/CV quality by itself |
+| Bench measurements | actual physical behavior | general correctness outside measured conditions |
+
+## R0 native tests
+
+### Pattern
+
+- default clear state;
+- set/toggle/clear;
+- bounds behavior;
+- full 16-bit mask;
+- deterministic 20k-operation property stress against a reference model.
+
+### Sequencer
+
+- stopped state emits nothing;
+- Start begins at step zero;
+- 16-step wrap;
+- deterministic ascending track trigger order;
+- Stop halts emission;
+- restart policy is explicit.
+
+### Sample clock
+
+- exact 120 BPM / 48 kHz / 16th-note interval;
+- non-integer BPM long-run schedule;
+- event location remains within one sample of ideal time;
+- invalid tempo/sample-rate rejection.
+
+### Pickup
+
+- no premature parameter jump;
+- capture inside tolerance;
+- capture on crossing;
+- direct tracking after capture;
+- normalized clamping.
+
+## CI policy
+
+R0 CI runs:
+
+1. ordinary host configure/build/CTest;
+2. repository validator;
+3. provenance validator;
+4. Python validator tests;
+5. independent ASan+UBSan build/test job.
+
+ARM/libDaisy build enters CI with P0. No public CI workflow may flash physical hardware.
+
+## Future P1 sonic regression
+
+Each synthesized voice will receive deterministic scenarios such as:
+
+- fixed trigger cadence;
+- fixed parameter tuples including corners;
+- fixed sample rate/block size;
+- statistical and waveform-derived signatures that tolerate intended floating-point variation;
+- explicit target-vs-host comparison where the same algorithm runs on both.
+
+Waveform hashing alone is not sufficient if benign compiler/FPU differences cause false failures. Use decision-useful metrics: peak/RMS, decay time, spectral centroid/bands, zero-crossing or envelope characteristics, and bounded numerical tolerances.

+# P0 Field Truth firmware contract
+
+This directory intentionally contains the P0 implementation contract before a target firmware claim is made.
+
+## Verified libDaisy API surface at pinned R0 reference
+
+At `libDaisy` commit `cc146d5065dd8286078a662e2830bf820c37a612`, `DaisyField` exposes the primitives needed for P0:
+
+- `Init()`;
+- `StartAudio()` / `StopAudio()`;
+- `StartAdc()`;
+- `ProcessAnalogControls()` / `ProcessDigitalControls()`;
+- `KeyboardState()` / rising/falling edges;
+- `GetKnobValue()`;
+- `GetCvValue()`;
+- `GetSwitch()`;
+- `SetCvOut1()` / `SetCvOut2()`;
+- public `gate_in`, `gate_out`, `midi`, `display`, `led_driver`, `seed`.
+
+`DaisySeed` exposes `SetLed()`, `SetTestPoint()`, `StartLog()`, `Print()` and `PrintLine()`.
+
+## Required P0 firmware behavior
+
+The first implementation should:
+
+1. stereo-pass audio in the callback without serial/display work in that callback;
+2. collect bounded callback timing instrumentation for the full callback interval;
+3. log raw 16-key scan indices outside the callback;
+4. report eight knob and four CV normalized readings at a rate-limited interval;
+5. report Gate In state/edges;
+6. report received MIDI events;
+7. provide OLED/LED functional indication outside the callback;
+8. keep CV/Gate outputs in a defined safe state except during an explicit momentary output test;
+9. emit machine-parseable telemetry such as `[HPF] key index=...`;
+10. never claim a physical mapping until the bench log ties raw indices to physical keys.
+
+## Completion
+
+A successful ARM build will be recorded as build evidence only. P0 remains incomplete until `evidence/p0/` contains real hardware data for controls, I/O, audio, MIDI, and timing.

+# Hardware notes
+
+Hardware-specific mappings are deliberately absent from R0 unless directly measured or taken from the verified official BSP.
+
+P0 will add:
+
+- Field serial number / hardware revision where available;
+- test fixture and instruments;
+- key scan-index map;
+- knob endpoint/direction table;
+- CV input calibration observations;
+- CV output code/voltage measurements;
+- Gate I/O levels;
