akgl_path_relative took its ENOENT branch by returning from inside the
HANDLE block, which skips the RELEASE_ERROR that FINISH ends with. The
handled context was never given back, so one entry of AKERR_ARRAY_ERROR
was lost per call and the 129th call hit "Unable to pull an error context
from the array!" and exited the process.
That branch is not an edge case: every asset path inside a tilemap is
resolved relative to the map's own directory, so it is taken several times
per map load. A game that loaded fifty levels died in the loader. It was
found by a benchmark that loaded the fixture map in a loop, which is the
first thing in this tree to call it more than a hundred times.
The fallback now runs after FINISH, so the context is released on the way
past. tests/util.c resolves AKERR_MAX_ARRAY_ERROR * 2 paths through the
branch and asserts the pool is where it started -- against the old code
that test does not fail, it terminates the suite.

libakerror 1.0.0 replaced the consumer-sized status-name array with a
private registry and made status-code ownership explicit and enforced.
AKERR_MAX_ERR_VALUE and __AKERR_ERROR_NAMES are gone, and the registry
entry points raise akerr_ErrorContext * instead of returning int. See
deps/libakerror/UPGRADING.md.
The break was not only source-level. libakgl's codes sat at
AKERR_LAST_ERRNO_VALUE + 18 through + 22, and 1.0.0 claimed exactly
those five offsets for its own AKERR_STATUS_* registry codes, so every
AKGL_ERR_* was aliasing a libakerror status. HANDLE(e,
AKGL_ERR_LOGICINTERRUPT) at physics.c:222 would have swallowed a
foreign-name refusal.
- Move the band to AKERR_FIRST_CONSUMER_STATUS (256) as fixed offsets,
so a libc that grows an errno cannot move the codes, and add
AKGL_ERR_OWNER, AKGL_ERR_LIMIT and AKGL_ERR_COUNT to describe it.
- Reserve the range and register the names through the owned entry
points, PASS-ing each: these are AKERR_NOIGNORE, and the old
akerr_name_for_status calls discarded failure silently.
- Drop the AKERR_MAX_ERR_VALUE=256 compile definition.
- Guard on AKERR_FIRST_CONSUMER_STATUS in include/akgl/error.h, which
now includes <akerror.h> so the guard is reliable. The embedded build
is fine, but the find_package path can pick up a stale installed
header, and 1.0.0 has an soname, so that pairing is an ABI mismatch
rather than a compile problem. Same guard libakstdlib already carries.
Registration also moves out of akgl_heap_init into a new akgl_error_init
in src/error.c. It was in the heap pool's initializer only because that
was the first thing akgl_game_init called, and the upgrade turned five
fire-and-forget name calls into a library-wide ownership claim that can
fail. That placement was hiding a defect: game.c raises AKGL_ERR_SDL
when SDL_CreateMutex fails, five lines before akgl_heap_init ran, so the
earliest error path in the library was guaranteed to print "Unknown
Error". akgl_error_init is now the first statement in akgl_game_init.
Callers that drive subsystems directly must call akgl_error_init first;
it is idempotent, so ordering it precisely is not required. The eleven
test suites that relied on akgl_heap_init to name their statuses now
call it explicitly, or their failure messages would have degraded to
"Unknown Error".
Add tests/error.c: assert every code reads back its registered name,
that the name table and AKGL_ERR_COUNT agree, that a foreign owner is
refused with AKERR_STATUS_NAME_FOREIGN and AKERR_STATUS_RANGE_OVERLAP,
and that repeating the init is a no-op. That last one is a live
constraint, not a triviality -- libakerror treats only an identical
reservation as a repeat, so a subset or superset raises.

Mechanical whitespace-only change across src/, include/, tests/, and
util/, applied with scripts/reindent.sh. No behavioral change.
Most files already conformed. The genuine outliers indented at 2 columns
(json_helpers.c, util.c from akgl_rectangle_points onward, assets.c,
staticstring.c, akgl_actor_add_child, util.h, staticstring.h) or used
spaces where the canonical form is a tab (draw.c). cc-mode also re-aligns
line-continuation backslashes in multi-line macros to its default
c-backslash-column, which is required for the tree to be a fixed point of
the indenter.
Verified whitespace-only: `git diff -w` over this change is empty apart
from three trailing blank lines removed at EOF in src/heap.c,
src/registry.c, and tests/tilemap.c. The build produces no new errors and
ctest is unchanged at 13/14, with `character` still the one intentional
failure.
The tree is now a fixed point of `scripts/reindent.sh --check`.
include/akgl/SDL_GameControllerDB.h is generated and excluded.
