v0.1.0-rc.15 — privacy-safe keyboard evidence

Changes

• Record cumulative Cardputer key activity by privacy-safe functional group: navigation, confirm/back, shortcuts, direct entry, and repeat.
• Never retain or emit individual key values.
• P0 now requires positive, internally consistent coverage of every control group and at least one held-key repeat.
• Added unit, evidence-auditor, real demo-log, and negative P0 coverage for the new counters.
• English and Simplified Chinese README pages document the new evidence boundary and remain packaged.

• Eight demo states and 60 native 320×170 locale/failure-state screenshots: PASS

Remaining release gate

This is a prerelease. A physical Cardputer Zero 30-minute P0 run and final Store install verification are still required before a stable release.

v0.1.0-rc.14 — superseded by v0.1.0-rc.15

Changes

• P0 resource sampling now records the Cardputer Zero board battery present flag and power-supply status on every sample.
• Evidence validation rejects a mid-run absent battery, missing status, or any status outside the official Linux power-supply values.
• Successful summaries report the observed charging-state set alongside capacity, voltage, and current ranges.
• Added an end-to-end collector regression using a running fake app, plus invalid mid-run presence/status coverage.
• English and Simplified Chinese README pages remain included in the repository and Debian package.

v0.1.0-rc.9 (superseded by rc.10)

RC9 strengthens Store-installed hardware validation and makes USB failures actionable on the 320×170 interface.

Highlights:

• Localized USB permission and device-busy states across all ten languages
• Replug/close-other-SDR recovery guidance instead of a generic device error
• P0 schema v2 checks the installed ARM64 app, librtlsdr0, plugdev membership, the distro udev rule, accessible USB High-Speed, framebuffer, keyboard, and ALSA
• 60 locale screenshots and eight deterministic receiver/failure states
• Complete Simplified Chinese README, also included in the Debian package
• Transient local and CI build paths removed from the device binary
• No app-owned udev rule, maintainer script, root service, network requirement, or cloud dependency

• ARM64/package/Store-policy CI: https://github.com/k1412/cardputerzero-sdr/actions/runs/31732104804

This remains a prerelease. Physical Cardputer Zero P0 validation is still required before Store submission.

Zero SDR v0.1.0-rc.8 (superseded by rc.9)

Hardware-validation candidate; this is not yet an App Store release.

这是实机验证候选版，尚未在 CardputerZero 应用商店上架。

Highlights:

• Passes the digest-pinned install-path policy from the authoritative CardputerZero/packages repository.
• Replaces the rejected app-owned system udev rule with the Debian 13 librtlsdr0 dependency, whose distribution package owns the RTL-SDR USB rule.
• Installs no root system service and no pre/post maintainer scripts.
• Uses Debian package revision 0.1.0-2, so RC7 installations can be upgraded reliably.
• Keeps the complete Chinese README linked from the repository home and packaged inside the .deb.
• Audits current Store dependency resolution and official image plugdev membership; a Debian 13 ARM64 simulated install resolves the complete dependency chain.

RC7 is superseded for Store preparation because its application-owned udev location is rejected by the current Store install-path policy.

Physical Cardputer Zero USB, audio, controls, display, thermals, and 30-minute stability remain the P0 release gate tracked in issue #1.

Zero SDR v0.1.0-rc.7

[!WARNING]

Superseded by RC8. RC7 contains an application-owned udev path rejected by the current CardputerZero Store policy; do not submit RC7 to the Store.

Hardware-validation candidate; this is not yet an App Store release.

Highlights:

• Honors the official Launcher display handoff: LV_LINUX_FBDEV_DEVICE, then inherited APPLAUNCH_LINUX_FBDEV_DEVICE, then the compiled /dev/fb0 fallback.
• Makes the packaged non-root P0 preflight resolve the same framebuffer path and verify its matching sysfs node is native 320×170.
• Adds host regression coverage for framebuffer precedence plus redirected-P0 checks for both APPLaunch and LVGL overrides.
• Pins the current official Cardputer Zero v0.0.4 BSP to its published SHA-256 and verifies both fresh downloads and cached archives.
• Records audited Template, Launcher, AppBuilder, dtoverlays, and BSP revisions in the upstream compatibility guide.
• Keeps the complete Chinese README and its prominent repository-home link in the package.

Zero SDR v0.1.0-rc.6

Hardware-validation candidate; this is not yet an App Store release.

Highlights:

• Aligns input discovery with the current official APPLaunch runtime: inherited keyboard environment, stable TCA8418 by-path node, then a single strict full-control evdev fallback.
• Rejects unrelated/partial input devices instead of binding every event node.
• Matches APPLaunch key repeat in userspace (500 ms delay, 50 ms cadence) because the official TCA8418 device tree does not enable kernel EV_REP.
• Automatically uses kernel repeat instead if a future keyboard node advertises EV_REP, preventing duplicate repeats.
• Tightens P0 preflight to require native 320×170 framebuffer geometry, the preferred Cardputer keyboard path, and an accessible ALSA playback PCM node.
• Keeps repeats limited to continuous tuning and settings-row movement; toggles, confirmation, direct entry, and page changes remain one action per press.

Zero SDR v0.1.0-rc.5

Hardware-validation candidate; this is not yet an App Store release.

Highlights:

• Adds packaged cardputerzero-sdr-p0 non-root preflight for framebuffer, Cardputer input events, RTL-SDR USB-node access, ALSA, memory, and thermal facts.
• Adds a bounded 30-minute evidence run with private output permissions, CPU/RSS/temperature samples, clean shutdown, early-exit detection, and a 10-second forced-stop fallback.
• Evidence intentionally excludes hostname, network state, and USB serials.
• Handles SIGINT/SIGTERM through the normal UI, receiver, audio, and device cleanup path.
• Expands host coverage to 13 tests and validates the P0 tool inside the final ARM64 package.
• Updates both English and Simplified Chinese README pages and the physical-device test procedure.

Zero SDR v0.1.0-rc.4

Hardware-validation candidate; this is not yet an App Store release.

Highlights:

• Adds flushed, timestamped receiver-health diagnostics for IQ throughput, RF errors, reconnects, audio output, DSP timing, and UI-loop stalls.
• Adds a tested 30-minute P0 log summarizer with explicit real-time thresholds.
• Skips WFM demodulation while muted or when audio is unavailable, preserving CPU for RF visualization.
• Expands ALSA recovery/failure metrics and host coverage to 11 automated tests.
• Updates both English and Simplified Chinese README pages and the physical-device test plan.

Physical Cardputer Zero USB, audio, controls, thermals, and 30-minute stability remain the P0 release gate tracked in issue #1.

Zero SDR v0.1.0-rc.3

Third Cardputer Zero hardware-validation candidate. This build queries the connected RTL-SDR tuner for its real discrete manual-gain profile, supports the FC0012 negative-gain steps, and defensively normalizes hardware requests. It also constrains Linux key repeat to continuous tuning/list movement, preventing held Enter or G/M/L/T keys from oscillating pages or values. Mutable settings now live only in the user XDG configuration directory.

Validation passed: 10 host tests, 50 locale/audio-state screenshots, 6 deterministic receiver states including manual gain, TrueType/glyf font validation, repository-default immutability, Store asset validation, and ARM64 package inspection.

This remains a pre-release. Physical Cardputer Zero RF/audio, USB power and permissions, thermals, keys, and sustained performance must pass issue #1 before App Store submission.

Zero SDR v0.1.0-rc.2

Second Cardputer Zero hardware-validation candidate. This build adds graceful audio-only degradation: live RF and spectrum continue when ALSA cannot open or suffers an unrecoverable write failure, while the radio and settings screens show a localized NO AUDIO state.

Validation passed: 9 host tests including startup/runtime audio failures, 50 locale and audio-state screenshots, 5 deterministic receiver states, TrueType/glyf font validation, Store asset validation, and ARM64 package inspection.

This remains a pre-release. Physical Cardputer Zero RF/audio, USB power and permissions, thermals, and sustained performance must pass issue #1 before App Store submission.
