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.

"""GET/PUT ``/api/v1/realism/config`` — operator-tunable realism knobs.
|
|
|
|
Today only the planner's content-class weights + canary probability
|
|
are exposed. The wire shape mirrors what
|
|
:func:`decnet.realism.planner.current_payload` produces and
|
|
:func:`decnet.realism.planner.apply_payload` consumes.
|
|
|
|
Reads accept viewer; writes are admin (writes mutate sampling
|
|
behaviour across the whole orchestrator fleet, same trust level as
|
|
the persona-pool surface).
|
|
|
|
The orchestrator worker periodically re-loads from the
|
|
``realism_config`` table; the API process applies overrides locally
|
|
on PUT so the GET-after-PUT round-trip reflects the change without
|
|
waiting for the orchestrator's next refresh tick.
