Marius CiepluchandClaude Opus 5 db3db6056d feat(model-grounded-detection): widen the settings table, wire the weak-algorithm arm
Two things, and a finding that says neither fixes the pairs that prompted them.

The settings table was Flask/FastAPI-shaped (CORS, set_cookie, app.run) while
the corpus contains aiohttp and Django applications, so three config_secrets
pairs contained no modelled security setting at all. Added aiohttp's
session_setup and cookie storages and Django's SECURE_* / DEBUG settings: 8
calls to 24.

And config_secrets spans three abstractions while only one was wired -- a
permissive setting VALUE. Weak algorithm CHOICE (CWE-326/327) is a different
thing: the danger is the algorithm NAMED, not a flag left open. Its data has
been sitting on the sink facts as `weak_literals` since before this feature and
nothing read it. Both abstractions read the same literal, so the arm is small:
hashlib.new("md5") is now entailed and hashlib.new("sha256") is not.

The finding: the three silent config pairs are CORPUS DEFECTS, not model gaps.
Measured similarity 23%, 45% and 53% -- dsvpwa-dsvpwa-main pairs `def main()`
against `def run(self, handler)`, a different function entirely. No settings
table can make those split, and it is worth saying so rather than letting the
work imply otherwise. The table gap was real and worth closing on its own
merits; it just is not why those pairs are silent.

734 passing, mypy/ruff clean, gates byte-identical.

Marius CiepluchandClaude Opus 5 8e26dfd1e2 feat(authorization-obligations): group sibling handlers and find consistency anomalies
Task 2.2. Handlers on the same resource under the same module are siblings;
when at least min_siblings of them discharge an obligation and one does not,
that one is the anomaly and the discharging siblings are its evidence (Req 3.2).
A set with fewer members than the minimum is under-populated and never reported
(Req 3.3). A public route among authenticated siblings is a missing path guard
with the mapper's access classification as evidence (Req 3.4).

The sibling key is the module path without its suffix, so two same-named files
in different directories are never merged. Witness validity (an identity
constraint counts only when it binds the authenticated context) is one helper
shared by operations, siblings and the checker.

Marius CiepluchandClaude Fable 5.1 f44dd2c512 feat(authorization-obligations): obligated operations and dischargers as closed facts
Task 1.1 (Req 1.1-1.5).

- semantic/obligations/facts.py: closed OPERATION_KINDS, DISCHARGER_KINDS
  and PROVENANCE_KINDS; OperationFact and DischargerFact (calls,
  decorators, identity sources, constraint params, request sources,
  permissive values); load_obligation_facts rejects unknown kinds and
  fields by name; per-language scoping.
- ruleset/obligations/{python,javascript,typescript}.toml beside (never
  inside) the flow facts directory. Protected reads and writes are
  discharged by an identity constraint or an ownership check; a path
  guard discharges privileged actions only.
