A list-of-non-dicts compile DB now raises by name inside the best-effort
tuple. The launcher rejection moved into parse_entry itself so no caller
can record ccache as the compiler, and the shape key includes the entry's
directory since relative includes resolve against it. format_bar raises
on a non-positive total so every consumer must handle the meaningless
bar; the espidf summary validates the RAM region by name (a malformed
region can no longer suppress a computable Flash line) and the blanket
backstop logs the traceback at debug. A new test pins that the CI
trigger paths exist on disk, so a rename fails loudly.
A compile DB that parses as valid JSON but is not a list now raises
EsphomeError inside IDEDATA_BEST_EFFORT_ERRORS instead of a TypeError that
fails an already-linked build. Cached idedata is validated on read against
the write path's guarantees (dict shape, no launcher as compiler, include
union present) so caches from older versions regenerate instead of serving
degraded data, and the served copy is re-stamped with the current ELF path.
Response-file shape sentinels key on the output object rather than the
source file, so two objects built from one source keep both include sets.
The size summary mirrors the standalone hardening PR: a blank partition
size cell raises by name, and a blanket guard keeps unexpected nested
shapes from raising past a build that already linked.
