A codename carries no ordering, so 'bookworm' and 'trixie' are two opaque
strings and no updater can tell that one supersedes the other. A pin that
names its Debian release that way is frozen on that release for as long as
it stands, and the freeze is invisible because the tag keeps resolving.
Numeric tags are comparable and stay inside the freshness pipeline, so the
rule is worth holding for the whole repository rather than fixing case by
case.
The check reads two shapes, because a codename reaches the tree in two
spellings. A 'name:tag' reference is recognised by the absence of a space
after the colon, which is what separates 'debian:bookworm' from the YAML
'image: python' and covers Dockerfile FROM lines and heredocs without a
second parser. A 'version:' value is read as a key, because '3.11-bookworm'
carries no colon at all.
False positives are kept out by two independent gates: a word-boundary
prefilter, so 'residual' and 'inside' are not read as 'sid', and a split of
the tag on '-', '.' and '_' that requires a whole component to be a
codename. That is what lets 'cache buster', '.stretched-link',
'fa-bullseye' and a tags list containing 'stretch' through. Every codename
occurrence in the repository was checked against the matcher by hand, and
the check was negative-controlled in both shapes, including an untracked
file.
Four references had to move for the rule to hold. meta/distros.yml takes
'debian:13' rather than '13.6': at depth 1 the updater can raise it across
a major, while depth 2 pins it inside the 13.x line forever. The whole
'make install' path was run in a debian:13 container to back that: all
twenty-four Depends and Recommends resolve on trixie, the docker repository
bootstrap derives the right suite and installs docker-ce-cli, and the
package builds and installs.
The workspace DiD probe moves to 'debian:13-slim'. An earlier version of
this change carried a suppression claiming the probe had to follow the
suite the apt proxy mirrors. That was wrong twice over: it cited a function
that has nothing to do with the probe, and the coupling does not exist,
because the cache frontend rewrites by path prefix and the suite never
enters a routing decision. Replaying the probe verbatim against
debian:13-slim fetches all three trixie suites through the
bookworm-configured proxies, so the suppression is gone rather than
reworded.
The rule ships with an escape hatch and no uses of it.

The env generator runs on the bare bootstrap python, before any
dependency is installed. utils/distros.py reached PyYAML through
utils.cache.yaml, so `python -m cli.meta.env` died with
ModuleNotFoundError on every dev-runtime image that ships python3
without PyYAML.
utils/yaml_bootstrap.load_block reads the block-YAML subset the SPOT
files use with stdlib only. It raises BootstrapYamlError on anything it
cannot parse identically to yaml.safe_load, so meta/distros.yml fails
loud instead of drifting.
The per-line regex lint meant to guard this is gone: one hop of
indirection defeated it and it stayed green while the invariant was
broken. It is replaced by a test that runs the real generator with
every non-stdlib import blocked.

categories.yml moves from roles/ to the repository-root meta/, joining packages.yml. utils/roles/categories.py owns its location plus the tree-walking helpers that were stranded in entity/name.py, so no caller spells the path or duplicates the lookup.
meta/distros.yml becomes the SPOT for every distribution: os_family, Galaxy platform name, dev-environment base image, and the pkgmgr/pkgmgr-virgin/environment reference templates. It replaces seven scattered copies (DISTRO_FAMILY, VALID_DISTROS, _DISTROS, _CANONICAL_PLATFORMS, two shell arrays, a Makefile literal). INFINITO_DISTROS is no longer a static default but generated by utils/env/handlers/infinito/distros.py; the shell consumers read it through the env layer.
Drops dead CLI surface found along the way: --categories-file and --roles-dir on the provision CLI plus three unused parameters of generate_dynamic_inventory, and the positional roles_file of the invokable categories command.
tests/lint/repository/test_distros_spot.py pins the copies that cannot call the SPOT (workflow literals, docs table) and forbids composing a pkgmgr reference outside it.
