What is Chord?
Chord's assistant can now write to the team's knowledge base, not just read from it.
Chord is a commerce data platform whose assistant, renamed from Copilot to Ask Chord in August, has absorbed most of the product's release capacity for four months. The latest release adds shared team memory: the assistant writes durable context back into its own knowledge base mid-conversation and can search it later. Preceding releases gave it audience building straight from conversation, grounding in the customer's own business definitions, persistent chat history and shareable conversations.
What is rjdqa?
rjdqa keeps refining one screen: the seasonal adjustment quality dashboard
rjdqa builds quality assessment dashboards for seasonal adjustment models produced by JDemetra+, aimed at official statisticians reviewing adjusted series. Essentially all development goes into two functions, simple_dashboard() and its denser variant simple_dashboard2(). Version 0.1.6 adds parameters to append observations to the forecast and to control whether the residual trading-days test is printed, defaulting to monthly series only, plus outlier table layout work and user-defined calendar regressor support in sc_dashboard().

Chord's assistant can now write to the team's knowledge base, not just read from it.
◆ Current state
Chord is a commerce data platform whose assistant, renamed from Copilot to Ask Chord in August, has absorbed most of the product's release capacity for four months. The latest release adds shared team memory: the assistant writes durable context back into its own knowledge base mid-conversation and can search it later. Preceding releases gave it audience building straight from conversation, grounding in the customer's own business definitions, persistent chat history and shareable conversations.
◆ Where it's heading
The arc runs from answering questions to acting and now to accumulating. Each release has closed one gap in that loop — answers that show their reasoning, then grounding in the customer's definitions, then feedback capture, then building audiences directly, and now retaining what it learns for the whole team. The rename from Copilot signals the assistant is being treated as the product surface rather than an add-on to it. Release notes arrive on a strict two-week cadence and the feed truncates their bodies, so specifics beyond the headline features are not visible.
◆ Prediction
Acting on that accumulated memory is the natural next step, since the assistant can already build audiences and now retains definitions across conversations.

rjdqa keeps refining one screen: the seasonal adjustment quality dashboard
◆ Current state
rjdqa builds quality assessment dashboards for seasonal adjustment models produced by JDemetra+, aimed at official statisticians reviewing adjusted series. Essentially all development goes into two functions, simple_dashboard() and its denser variant simple_dashboard2(). Version 0.1.6 adds parameters to append observations to the forecast and to control whether the residual trading-days test is printed, defaulting to monthly series only, plus outlier table layout work and user-defined calendar regressor support in sc_dashboard().
◆ Where it's heading
The package has converged on a single deliverable and is tuning it against reviewer practice. Each release adds a parameter that lets the analyst include or exclude one element of the dashboard, or adjusts how densely information is packed into the fixed space of the layout. The td_effect default — print the test only for monthly series — is characteristic: the knowledge about when a diagnostic is meaningful is being encoded into the tool rather than left to the reader.
◆ Prediction
The pattern of adding one toggle per diagnostic per release points at the same thing again, most likely another test given a conditional default, rather than a new dashboard function alongside the two that exist.
