Embedded Traceability

This local traceability register connects the Embedded intended-behavior pages to the requirements baseline. Entries are deliberately medium-granularity so that each behavior can be reviewed against firmware later without treating implementation as the source of truth.

E1000001

Controller coordination claim in the table below.

E1000002

Detector timing claim in the table below.

E1000003

Effective-pixel acquisition claim in the table below.

E1000004

USB frame-completeness claim in the table below.

E1000005

Driver-board interface claim in the table below.

E1000006

Calibration and evidence claim in the table below.

Embedded behavior traceability
ID	Behavior claim	Defining pages	Alignment state	Future evidence location	Requirements evidence
`E1000001`	The STM32F411CEU6 coordinates detector timing, acquisition, frame ownership, and USB handoff.	`controller/system_controller/Embedded Architecture`	Not Started	Firmware review and controller verification	Requirements And Metrics; Design Document functional and resource requirements
`E1000002`	The controller generates fM near 2 MHz, ICG with an 8 ms period and 7.388 ms pulse target, and SH with a 10 microsecond pulse target.	`timers/CCD Timing`; timer detail pages	Not Started	Timing-reference captures	Requirements And Metrics; Design Document CCD timing requirements
`E1000003`	Acquisition preserves all 3648 effective detector pixels in order.	`acquisition/adc_dma/ADC And DMA Capture`	Not Started	ADC/DMA capture evidence and frame-geometry check	Requirements And Metrics detector geometry
`E1000004`	A transferred frame is complete and carries frame identity and status information.	`usb_cdc/binary_frame_stream/USB CDC Stream`	Not Started	Integration contract and USB stream verification	Requirements And Metrics USB transfer
`E1000005`	The driver-board interface routes timing and analog signals while supporting power integrity and pre-power continuity checks.	`driver_board/ccd_interface/Driver Board Interface`	Not Started	Board inspection and interface verification	Design Document embedded and EMC design requirements
`E1000006`	Timing-reference and frame-geometry checks produce linked evidence and an explicit unresolved disposition when requirements are missing.	`calibrations/timing_reference`; `calibrations/frame_geometry`	Not Started	Test and Verification evidence register	Requirements And Metrics; calibration and characterization guidance

Open contract items include total transported sample geometry, packet encoding, integration-time semantics, ADC trigger details, exact signal ownership, hardware electrical limits, and evidence retention rules. These remain Not In Docs until the responsible section defines them.
