337520c7ad fix(security): close INFO ASVS findings — secret echo, TLS floor, mandatory tarball SHA, CORS/Content-Type guards, BUG-17
- V7.1.3: env known-insecure-default error no longer echoes the rejected secret value.
- V9.1.4: syslog-over-TLS forwarder + listener pin minimum_version=TLSv1_2.
- V12.1.2: updater tarball SHA-256 verification is now mandatory and fail-closed —
  /update and /update-self reject a missing digest (400), the executor rejects
  missing/mismatched digests before extract/apply. Every push path supplies it.
- V13.1.4: reject a wildcard '*' in DECNET_CORS_ORIGINS at startup.
- V13.1.5: enforce application/json on JSON write endpoints (415 otherwise),
  exempting multipart upload routes.
- BUG-17: SSE error log records the user uuid, not the resume cursor.

Also completes V2.1.7 consistently: the attacker-injectable PYTEST* env bypass is
replaced with explicit DECNET_TESTING=1 in the three remaining sites
(env.validate_public_binding, config logging, mysql url builder).

Tests added for every fix; unanimous adversarial review (no update-outage risk —
all push paths verified to send the digest).

245975a6dd fix(security): close LOW ASVS findings — env bypass, SSE/deployment authz, CN fail-close, password byte-limit, exception leaks, BUG-12..16
Auth/session (V2.1.7, V4.1.5, V4.1.6, V2.1.4/V2.1.5):
- env secret validation no longer bypassed by attacker-injectable PYTEST* env;
  gated on explicit DECNET_TESTING=1 (set only in conftest).
- must_change_password now enforced on the SSE header-JWT path, not just ticket mint.
- GET /system/deployment-mode requires viewer auth (was leaking role + topology size).
- CreateUser/ResetUser passwords min_length=12; passwords >72 bytes rejected
  explicitly instead of bcrypt silently truncating.

Swarm ingestion (V9.1.3, BUG-16):
- Log listener hard-rejects peers with unparseable/empty cert CN (fail closed,
  ingests nothing) instead of tagging 'unknown'.
- Shutdown handlers no longer swallow real errors (narrowed to CancelledError).

Info leakage (V7.1.2, V14.1.2):
- Exception text sanitized on swarm-update, health, tarpit, realism, file-drop,
  blank-topology endpoints (raw tc/docker stderr, DB/Docker errors logged
  server-side, generic detail returned). pyproject license corrected to AGPL-3.0.

Correctness (BUG-12..16):
- BUG-12 atomic credential upsert (UNIQUE constraint + IntegrityError retry,
  consistent principal_key canonicalization).
- BUG-13 rule-tail watermark uses >= with seen-id dedup (no same-second drop).
- BUG-14 worker wake cleared before wait (no lost wake during tick).
- BUG-15 intel gather tolerates an unexpected provider raise.
- BUG-16 see above.

Already-closed (verified, no change): V2.1.6, V5.1.3, V9.1.2. Accept-risk +
documented: V2.1.8 cache window, V3.1.3 idle timeout. Tests added for every fix;
unanimous adversarial review after two refute-fix rounds.

fdb6507c6f fix(env): fail closed on weak DECNET_ADMIN_PASSWORD
DECNET_ADMIN_PASSWORD defaulted to the literal "admin" with no guard, so
a master that never set it seeded an admin/admin account. Resolve it
lazily via __getattr__ -> _require_env (the same pattern as
DECNET_JWT_SECRET): unset or a known-bad default (admin/secret/...) is
rejected, and <12 chars is rejected outside DECNET_DEVELOPER. Only the
master web/api processes that import the DB layer resolve it; workers
never do, and the pytest short-circuit keeps the dev loop unaffected.
The module attribute stays addressable for the admin-seed monkeypatch.

f2b3393669 chore: relicense to AGPL-3.0-or-later and add SPDX headers
Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file
across decnet/, decnet_web/, tests/, scripts/, and tools/.

Rationale: closes the GPLv3 ASP loophole so any party operating a
modified DECNET as a network service must offer their modified
source. Personal copyright (Samuel Paschuan) + inbound=outbound
contributions make a future unilateral relicense infeasible.

- LICENSE: full AGPL-3.0 text (gnu.org/licenses/agpl-3.0.txt)
- COPYRIGHT: project copyright notice
- tools/add_spdx_headers.py: idempotent header injector
  (shebang- and PEP 263-aware)

Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.

8d3f5c646a fix(network): accept CAP_NET_ADMIN in lieu of euid==0 for macvlan setup
The systemd unit grants AmbientCapabilities=CAP_NET_ADMIN so the API
service can program host-side macvlan/ipvlan interfaces without
running as root, but setup_host_macvlan/_ipvlan rejected with euid!=0
before even trying — making web-driven 'decnet deploy' impossible
under the privilege model the unit advertises.

Replace _require_root with _require_net_admin, which reads CapEff
from /proc/self/status and accepts the cap (bit 12) as well as
euid==0. No libcap dep — pure /proc parse.
