The seed-drift guard shipped as refuse-boot: the backend exited when
BACKEND_DICT_VERSION disagreed with the flat dir's recorded .seed_version. On
the test contour that turned a harmless-in-intent action — bumping the
TEST_DICT_VERSION variable to the active release (v1.2.1) on a volume seeded as
v1.0.0 — into a crash loop, because DICT_VERSION is the *seed* of a fresh
volume, not the active version (which the admin console drives).
Make the marker authoritative instead: OpenWithVersions resolves the flat dir's
version from .seed_version when present and ignores bootVersion on an
already-seeded volume; bootVersion only seeds a fresh volume's marker. So a
bumped build seed on a live volume is a no-op (it can't relabel live bytes and
can't void games pinned to the prior label), and it correctly seeds the next
fresh volume. The subdirectory scan now skips the resolved seed, so a version
also present as a subdir (e.g. v1.2.1 uploaded via the console while the build
seed is bumped to v1.2.1) is still loaded rather than shadowed by the flat bytes.
Tests: marker-wins over a bumped boot version; a bumped boot keeps the matching
subdir resident (the live-contour case). Docs updated (ARCHITECTURE §5, READMEs,
compose/.env, PRERELEASE DV) from "refuses to boot" to "marker wins / ignored".
Verified locally against v1.2.1: gofmt, build, vet, unit, integration green.
The dictionary release moved to v1.2.1 while DICT_VERSION stayed pinned at
v1.0.0 in CI and the image/compose seed defaults. Two problems:
1. CI validated against a stale dictionary.
2. The contour seed could be bumped on a live volume, which silently relabels
the already-seeded bytes — voiding games pinned to the prior label and
serving the wrong dictionary for new ones. The flat DAWGs carry no embedded
version, so this drift was undetectable.
Changes:
- Seed-drift guard: OpenWithVersions records the flat dir's version in a
.seed_version marker on first boot and refuses to start when a later
BACKEND_DICT_VERSION disagrees. DICT_VERSION is now the seed for a *fresh*
volume only; a live contour migrates through the admin console (old versions
stay resident, in-progress games keep replaying).
- Track the current release: CI's DICT_VERSION centralised to one workflow-level
env (v1.2.1); image/compose/.env seed defaults bumped to v1.2.1. The deploy
job keeps reading the per-contour vars.TEST_DICT_VERSION.
- Docs: ARCHITECTURE §5 (decision record), backend/deploy READMEs, PRERELEASE
tracker (DV row).
Verified locally against the v1.2.1 artifact: gofmt, build, vet, unit and
integration (-tags=integration) all green.
Replace the dictionary hot-reload with an online update flow in the GM console
(/_gm/dictionary): the operator uploads scrabble-dawg-vX.Y.Z.tar.gz, previews the
per-variant words added/removed against the active dictionary, and confirms to
install + activate it. Versions are immutable; in-progress games keep their pinned
version while new games use the new one.
- engine: DiffWords (enumerate both DAWGs, decode only the differences), OpenFinder,
Registry.Finder, DictFiles; OpenWithVersions skips the .staging area.
- dictadmin: hardened release-archive validation + extraction (path-traversal,
symlink, oversize, entry-count rejection) and staging -> install (atomic rename).
- game: active dictionary version persisted in the dictionary_state singleton
(single source of truth, restored on boot), concurrency-safe accessor.
- storage: BACKEND_DICT_DIR is a named volume seeded from the image (nonroot-owned),
so uploaded versions persist across redeploys; the build's DICT_VERSION labels the
seed and equals the resident tag (BACKEND_DICT_VERSION).
- docs: ARCHITECTURE §5, FUNCTIONAL (+ru), backend README, TESTING, PRERELEASE.
Tests: engine + dictadmin unit; integration upload->preview->install->activate->
restart->pin->immutability->CSRF.
Squash the 12 goose migrations into one 00001_baseline.sql (there is no prod
data; verified schema-identical to the chain via a pg_dump diff + the green
integration suite) and rename the game-variant labels
english/russian_scrabble/erudit -> scrabble_en/scrabble_ru/erudit_ru across the
backend, the FlatBuffers wire values and the UI.
dawg filenames and the Go enum identifiers are unchanged; the i18n display keys
are kept. Adds PRERELEASE.md (the R1-R7 pre-release tracker), linked from
CLAUDE.md. Contour DB wipe and the scrabble-dictionary tidy are follow-ups.
