The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.
Project context
Fictional cooperative Quarry reviews synthetic service-volume reports. Build local report fixtures with empty, missing and delayed values.
Setup prerequisites
- Create synthetic report series with explicit missing values.
- Stub report loading, sorting and export responses.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- CTABLE-102 · Preserve table header associations in the reporting workbench
- CTABLE-101 · Give report charts a textual trend summary
- CTABLE-103 · Represent missing report observations distinctly from zero
- CTABLE-104 · Expose report sorting through semantic header buttons
- CTABLE-105 · Keep report filter errors near their controls
- CTABLE-106 · Provide a keyboard alternative to chart range brushing
- CTABLE-107 · Keep report details discoverable after virtualized rows leave view
- CTABLE-108 · Announce reporting export readiness without stealing focus
- CTABLE-109 · Keep report distinctions visible in forced-color mode
Acceptance criteria
- Audit compares values and gaps
- Keyboard sort and export are covered
- Unresolved limitations remain explicit
Implementation constraints
- Record environment and actual observations.
Verification to include
- Find highest known interval both ways
- Inspect missing data and failed export
Deliverables
- Audit protocol and findings
Rollout and recovery
Block wider report rollout for reproducible information loss.
Value of the work
For the engineer: Practice semantic data presentation and robust interaction.
For the team: Inspect whether reporting decisions remain possible without color or pointer use.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
