# Changelog

All notable changes to `event4u/agent-config` are documented here.
Format loosely follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/);
versioning policy is documented in [CONTRIBUTING.md](CONTRIBUTING.md#versioning-policy).
Entry-shape contract: [`docs/contracts/CHANGELOG-conventions.md`](docs/contracts/CHANGELOG-conventions.md).

> Entries before 1.3.3 were reconstructed from git history after the fact.
> Early releases did not maintain release notes.
>
> History is split into **eras**. The current era keeps full entries
> inline; prior eras collapse into a single pointer to an archive file
> under [`docs/archive/`](docs/archive/). A drift test
> (`tests/lib/changelog_eras.test.ts`) forces an era split before the
> current era grows past 250 lines.

> **Retro-curation disposition, 2026-09-01** — roadmap
> `road-to-publication-integrity-hard-fail`, blocker `b-retro-curation-scope`,
> option (c). The `### Release highlights` heads of 14.9.0 through 14.13.0 were
> written by the release generator and published without the editorial pass they
> ask for. Two things were repaired: the generator's own authoring instruction,
> which was never release content, is deleted from this file, and the writer no
> longer emits it. The generator-derived head lines below are **preserved as
> published** and deliberately not paraphrased — rewriting a derived claim is
> editorial judgement two prior councils reserved, and a paraphrase of the
> generator's own reason would be truthfully documented uselessness.
> [`docs/archive/`](docs/archive/) is left untouched as historical record. The
> annotated tag messages and the published GitHub Release bodies for 14.9.0
> through 14.13.0 are **immutable** and cannot be repaired at all.

## [Unreleased]

_Nothing staged._ Twenty entries that had accumulated here were drained to
[`docs/archive/CHANGELOG-unreleased-drain-2026-10.md`](docs/archive/CHANGELOG-unreleased-drain-2026-10.md)
on 2026-10-13; every one of them had already shipped, the oldest in 9.7.0.
An entry belongs under a dated release section, not here — see
