Technical Changelog · Verifiable evolution
System changes, not empty announcements

Technical evolution should leave a trail.

This changelog summarizes architectural and engineering milestones in CTG One’s professionalization. It does not replace Git history or document every commit; it identifies changes that materially affect platform capability, security, or verifiability.

P01

Credibility hardening

Separated verified capabilities from roadmap claims and corrected outdated deployment/security narratives.

P02

CTG One OS

Formalized the shared technology layer and maturity model across identity, data, transactions, automation, security and intelligence.

P03

Products & case studies

Introduced evidence-based product case studies with CTG Craft Beer Investment as CASE-001.

P04

AI architecture & governance

Defined AI boundaries, human-in-the-loop controls, evaluation requirements and promotion criteria.

P05

Security, observability & testing

Added health checks, structured redacted logging, critical safety invariants, dependency audit thresholds and stronger headers.

P06

Ecosystem technology mapping

Mapped each business unit to operating problems, CTG One OS modules and verified maturity states.

P07

Public technical proof

Introduced public status, Labs framework and technical changelog as verifiable evidence surfaces.

P08

Production readiness

Defined the Render deployment contract, health checks and production verification runbook.

P09

AI platform architecture

Expanded CTG One AI with Citation-First RAG, agent runtime, risk tiers, evaluation, security and CTG Knowledge product architecture while retaining IN DEVELOPMENT status.

P10

CTG Knowledge v0.1

Implemented the first authenticated RAG pilot with curated ingestion, pgvector retrieval, server-side model access, grounded answers and structured source metadata; LIVE promotion remains evidence-gated.

P11

Grounding integrity hardening

Added deterministic post-generation citation validation so CTG Knowledge fails closed when model output lacks citations or references sources that were not supplied for the request.

P12

Reproducible AI evaluation

Added a provider-independent evaluation harness, synthetic CI fixtures, regression thresholds and explicit separation between test evidence and authorized semantic/operating evidence.

P13

Versioned evaluation corpus

Added a representative first-party public evaluation corpus and dataset, pinned to exact Git blob identities with fail-closed provenance and drift validation before controlled run capture.

P14

Controlled evaluation capture

Added explicit-authorized isolated corpus seeding, real query capture, human semantic review worksheets and fail-closed conversion into authorized evaluation evidence; the first authorized human-reviewed run still pending.

P15

Participant liquidity loop

Closed the participant settlement-to-reinvestment loop with server-priced case intent, shared balance/capacity reservations, immutable participant quantity, cancellation/rejection paths and a participant reinvestment console while retaining BETA status.

P16

Finance reinvestment queue

Added a bounded Finance OS review queue for pending reinvestments with current KYC, source-credit, spendable-balance and target-lot context, while approvals remain immutable server-side commands.

P17

Operational Golden Journey

Added a bounded per-lot lifecycle reconstruction and a clean-database transactional journey proving funding, payment, production, sale/return, settlement, reinvestment and confirmed payout as one conserved operating loop.

P18

Investment production readiness canary

Added a public-safe read-only readiness endpoint and post-deploy canary that pin exact Render identity, runtime schema compatibility, PARTIAL/BETA truth and the canonical Investment surface while keeping real operating evidence explicitly pending.

P19

Investment operating evidence capture

Added a private-by-default redacted operating-evidence pipeline with source hashing, PII/identifier rejection, financial conservation checks, explicit human review and synthetic-vs-production evidence separation; real production evidence remains uncaptured until an authorized review is performed.

P20

Investment release gate matrix

Added a SUPER_ADMIN release-readiness read model that consolidates technical proof, Render/schema state, reviewed operating evidence, pending business decisions and fail-closed exposure controls while prohibiting automatic LIVE promotion.

P21

Production readiness evidence capture

Extended the existing post-deploy canary with versioned, SHA-bound, public-safe PASS/FAIL artifacts and a shared validation contract reused by release governance; artifact generation never auto-accepts release evidence or changes PARTIAL/BETA maturity.

P22

AI model gateway hardening

Introduced a shared server-only model gateway for CTG Knowledge with explicit provider allowlisting, versioned runtime configuration, bounded timeout/retry policy, request correlation and structured provider/model/token telemetry while keeping the AI layer IN DEVELOPMENT and CTG Knowledge BETA.

P23

Observability trace and error intelligence

Added W3C trace-context propagation, a versioned structured telemetry schema and safe classified error fingerprints on critical health and knowledge paths while keeping centralized metrics, alerting and full distributed tracing explicitly PARTIAL.

P24

VÉRTICE federation registration

Registered the existing "Entrar con CTG One" authorization-code + PKCE federation with VÉRTICE OS in public technology proof and the ecosystem contract registry, documenting the server-to-server exchange, KYC assurance claim boundary and mobile BFF reuse while keeping the entry PARTIAL/BETA pending end-to-end production operating evidence.

Transparency policy

Changelog entries do not automatically make a capability LIVE. Technical status is published separately and requires sufficient evidence.
