v0.1.0-alpha.490

Released 2026-10-16.

Features

Caching

  • The load management window also applies to a materialized view, meaning: outside the window the view may not be read by a user''s workload.
    • A materialized view's load management window says when a user's read may read it

Demo Provisioning

  • A visitor's demo sandbox is released soon after its tab closes.
    • A visitor's sandbox is released soon after its tab closes

Tag Registry

  • Tag IDs are emitted into the bracketed comment suffix alongside the modeling role, so a catalog surface shows [dimension, entity, natural_language] where it shows [fact, scd2] today (append_modeling_tag, provisa/core/modeling_tags.py,) — reaching pg_description, GraphQL introspection and the Flight/MCP catalog description through the one shared formatter.
    • Tag ids ride in the catalog description suffix

URI Dereferencing API

  • Governed dereference API for semantic data-location URIs: REST and MCP tool resolve(uri, as_of?) that takes a Provisa semantic-address URI and returns the governed value(s) it addresses, optionally at a point in time.
    • Dereference a semantic address on GraphQL, REST and MCP
    • Every role's service resolves a semantic address

Changes

api

  • A vector model error on GraphQL answers 400 naming the model, as SQL does

audit

  • A GraphQL request's row records the status its client was answered

auth

  • A member's attributes -- the org's record over the provider's claims
  • derived roles -- a role held for what a member's attributes say about a declared claim type
  • A regional node's own work carries its region derived role

billing

  • The current bill and the next charge are amounts
  • A billing date shows its calendar day in every time zone

data

  • A still-starting source answers 503 on /data/sql and REST; demo tests wait for govdata

demos

  • A demo with no seeder bundles
  • The insider review demo
  • Reviews and vulnerabilities name their fields as their sandbox does
  • A demo's profiler runs at its template build and its sandboxes carry the runs
  • A sandbox's tour is warmed in the background as it opens
  • A demo's setup makes an environment, and its tour picks one
  • The testdata demo -- realistic test data without touching production
  • The sonnets Qdrant store recovers its snapshot at every start
  • The sonnets vectors source reads with the store's read-only key
  • The local government vertical -- opioid settlement spending against overdose deaths
  • A demo store is healthy only once its first-start load has ended
  • A bitemporal view's history travels with its demo's bundle
  • The data vault demo, Northwind in two sources, its vault declared as views
  • The data vault declares its masks as a column's masks list

deploy

  • Every cloud deploy refreshes the demo-stores sync and its units
  • A cloud deploy reaches the sandbox VM too

deps

  • Mcp 1.30.0, past CVE-2026-59951

domains

  • A domain tree -- a business unit and the organizations within it
  • The domains query reads its rows' steward and parent; no requirement id in a view
  • The parent picker's explanation is its field's hint

environments

  • A whole-model merge request stores its selection as SQL NULL

explorer

  • Show SQL shows the statement the compiled pipeline runs
  • Show SQL is governed by the compiled pipeline's own stage

fakes

  • A hash of an integer column narrower than BIGINT fits its type (#272)

federation

  • The attach walk leaves alone a table Provisa reads itself
  • A statement on a source whose server is still starting waits, then answers 503 by name
  • An incomplete attach walk waits its retry interval, and logs a failure once

files

  • Connector bundles download off the request path; an unanswered catalog query is retried

governance

  • A condition on a union's output relates no branch to another (#271)

graphql

  • A PostgreSQL double precision column maps to Float

grpc

  • A PostgreSQL double precision column is a proto double

install

  • The control-plane compose splits into the control plane and the sandbox tier by profile

join guard

  • A join on a column a view computes relates along the view's relationship (#270)

join-guard

  • A filter on a value computed over a union view relates nothing

kafka

  • A Kafka live table lands every message it can read, in every org that declares it
  • Every org reads a CDC topic whole, and keeps its own SingleStore pipelines

landing

  • A pgwire connector table (govdata among them) lands through its landing filter

masking

  • A regex mask replaces every match on every engine

openapi

  • A config-declared OpenAPI source states its auth

orgs

  • Destroying an org stops its connector servers

pgwire

  • A server bound off loopback is reached where it listens; endpoint fixtures ready the org folder
  • A caller that waits has an unanswered first catalog query sent again within its wait

profiler

  • A configuration names a profile result table by its member and kind

replicas

  • A build waits for a source server that takes minutes to start
  • Each environment has its own build runner; one built after prod no longer replaces prod's (#273)

sandbox

  • A demo sandbox carries its template's environments, and its visitor switches between them

sandbox-tier

  • The tier finds the deployment's demo SQLite data

sandboxes

  • One connector server per demo version, shared by its sandboxes
  • A sandbox tier on a VM of its own stops that VM when no sandbox is used

security

  • Composite grants -- an entry a+b is held by a reader holding all of it
  • A column's masking is one ordered mask list, first entry held applies

sla

  • service-level limits are settings, breaches are stored and listed in ops

subscriptions

  • A subscription on a push-landed table re-runs when a batch lands

tables

  • A table may fix the arguments its source takes by name
  • A table's landing filter is applied when its replica lands

temp-tables

  • session_temp_schemas is kept in the region's state store

terraform

  • The sandbox tier on a VM of its own

ui

  • A scoped merge's object ticks sit in the form's FormChecks
  • The table form sets a table's landing filter and fixed arguments
  • The grant picker's combine button takes its hint from Tip

ui-server

  • A request for the sandbox tier starts its VM when it finds it down
