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.

"""POST/DELETE /api/v1/deckies/files — generic file drops on deckies.
|
|
|
|
Wraps :func:`decnet.decky_io.write_file_to_container` /
|
|
:func:`decnet.decky_io.delete_file_from_container` so admins can drop
|
|
arbitrary bytes at arbitrary paths inside a running decky container —
|
|
fleet OR MazeNET — without going through the canary surface.
|
|
|
|
Auth: ``require_admin`` everywhere (matches every other write op on
|
|
deckies; see :mod:`decnet.web.router.fleet.api_mutate_decky`).
|
|
|
|
Container resolution mirrors the canary path: ``topology_id`` absent
|
|
means fleet (``<decky>-ssh``), present routes through
|
|
:func:`decnet.decky_io.resolve_decky_container` for the MazeNET
|
|
``<decky>-ssh`` / ``decnet_t_<id8>_<decky>`` distinction.
