C-6: ConnectorRuntime enforces capability_mask per operation.
READ-only ACs cannot invoke MUTATE operations (wipe, lock, retire).
C-7: AC validated against database (exists, active, not expired)
before connector invocation.
C-9: Delegated AC capability bounded by delegator's capability.
C-10: Command counter uses atomic SQL increment with limit check.
M-23: expire_stale() uses same atomic SQL pattern.
H-1: Sensitive credential fields hidden from repr/logs via repr=False.
H-2: Stub backend requires ALLOW_STUB_CREDENTIALS=true to activate.
H-3: Kerberos backend raises CredentialResolutionError instead of
returning stub ticket.
H-4: Chronicle INTENT emitted before execution, RESULT after.
H-5: device_id validated as UUID before Graph API URL interpolation.
H-8: ConnectorRuntime enforces governance for all connector invocations.

Pygments
|
|
~~~~~~~~
|
|
|
|
Pygments is a syntax highlighting package written in Python.
|
|
|
|
It is a generic syntax highlighter for general use in all kinds of software
|
|
such as forum systems, wikis or other applications that need to prettify
|
|
source code. Highlights are:
|
|
|
|
* a wide range of common languages and markup formats is supported
|
|
* special attention is paid to details, increasing quality by a fair amount
|
|
* support for new languages and formats are added easily
|
|
* a number of output formats, presently HTML, LaTeX, RTF, SVG, all image
|
|
formats that PIL supports, and ANSI sequences
|
|
* it is usable as a command-line tool and as a library
|
|
* ... and it highlights even Brainfuck!
|
|
|
|
The `Pygments master branch`_ is installable with ``easy_install Pygments==dev``.
