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.
Seven instrumenters that mutate operator-supplied artifacts to
embed the callback URL:
- passthrough — bytes unchanged; only DNS-callback tokens trip
detection, with the slug embedded in the placement path
- plain — substitutes {{CANARY_URL}}/{{CANARY_HOST}} placeholders;
falls back to appending a comment line whose prefix adapts to the
apparent file syntax (#, //, ;)
- html — injects a 1x1 tracking pixel before </body>, appends
if the close tag is missing
- docx — direct zipfile manipulation (no python-docx dep):
inserts an external-image Relationship into word/_rels/document.xml.rels
and a matching <w:drawing> element before </w:body>
- xlsx — sibling of docx; injects an external-image relationship
into xl/_rels/workbook.xml.rels (orphan rels are still fetched on
open by most viewers)
- pdf — uses pikepdf to install /OpenAction /URI on the catalog;
rejects with a clear message when pikepdf isn't installed
- image — uses Pillow to embed slug + URL in PNG tEXt / JPEG
comment; rejects with a clear message when Pillow isn't installed
DOCX and XLSX share the rId allocator + relationship injector via
the docx module; both work on stdlib zipfile only.
Tests synthesise minimal real DOCX/XLSX fixtures inline, round-trip
each instrumenter, and assert the callback URL ends up in the
mutated bytes while the file still parses.
