P1-14 deploy/install/restic-manager-agent.service: standard systemd
unit with the usual hardening switches (NoNewPrivileges, Protect*,
RestrictRealtime, MemoryDenyWriteExecute). Restart=always with a
5s backoff. Runs as a dedicated unprivileged restic-manager-agent
user; the install script creates it.
P1-29 deploy/install/install.sh: arch detection (amd64/arm64), pulls
the agent binary from /agent/binary, creates the service user
+ dirs (/etc/restic-manager, /var/lib/restic-manager), runs
enrollment via `agent -enroll-server -enroll-token`, lays down
the systemd unit, enables and starts it.
Honours the spec's "detect, don't auto-disable" rule for existing
schedulers: scans systemd timers, /etc/cron.d/*, /etc/cron.daily/*,
root crontab for restic-named entries and prints them with the
exact disable command — operator decides.
P1-31 server endpoints to ship the agent installation payload:
GET /agent/binary?os=linux&arch=amd64 → serves
<DataDir>/agent-binaries/restic-manager-agent-linux-amd64
GET /install/<file> → serves
<DataDir>/install/<file>
Both endpoints reject path traversal and return 404 if the file
isn't published. Operators drop the binaries + service unit into
these directories at release time. Signed-bundle verification is
deferred to Phase 5 OSS readiness.
All tests still pass.

Lands the bottom three layers of Phase 1:
P1-08 internal/api: protocol_version + envelope + every WS message
shape from spec.md §6.2 (Hello, Heartbeat, Job*, Schedule*, etc).
Wire-format tests pin the JSON shape so a rename here breaks
tests instead of silently breaking the agent.
P1-02 + P1-03 internal/store: SQLite via modernc.org/sqlite,
embed.FS + a tiny version table for hand-rolled migrations.
0001_initial.sql covers every table from spec.md §5 plus
enrollment_tokens and host_schedule_version. Typed accessors
for users / sessions / enrollment / audit. WAL + foreign_keys
+ busy_timeout on by default.
P1-06 internal/crypto: XChaCha20-Poly1305 AEAD wrapper with
per-message random nonce. Key file lifecycle (generate +
refuse-to-overwrite, load with size validation). Optional
additionalData binds ciphertext to the row that owns it.
P1-04 internal/auth (partial — passwords + tokens; sessions
middleware lands with the HTTP handlers): argon2id following
RFC 9106 (64 MiB / t=3 / p=4 / 32B), constant-time verify.
HashToken stores SHA-256 of session/agent/enrollment tokens
so a stolen DB doesn't hand over credentials.
Build floor moves to Go 1.25 (modernc.org/sqlite v1.50+ requires
it); CI + Dockerfile + README updated. Markdown lint diagnostics
on tasks.md cleared.
All packages tested. ~70 new tests pass in <1s.
