This extends dbcb230 to the remaining graph-integrity gaps. In the independent
evaluation these gaps were repository-wide:
- alerta: one symlink, `alerta/app.wsgi`, which is not even source, made 261 of 261
questions unresolved.
- wger and Signal K: a language no frontend reads did the same.
- YesWiki: unparsed files did the same.
Now:
- the partition build records the paths a symlink boundary skipped (a directory
ends in `/`) and the languages no frontend reads;
- `files_unparsed` carries its full paths;
- the scan demotes only questions about an owned path or under an owned directory,
and only questions in an owned language.
Every gap stays in the report as a boundary. A gap that names nothing keeps its
partition-wide or repository-wide reach. Tier-0 pruning stays off, as before.
The tests that pinned repository-wide reach now assert ownership. The one about a
vendor exclusion masking an integrity failure keeps its intent, using a census gap
that names no file.
Retune after protocol-v1; exploratory only.

The 7.8 trace showed the completion loss was a sizer death spiral, not
expensive families: after two kills the budget fell to 3 sink visits and
never recovered, because portions finishing in 25-30 s sat under an assumed
70 s fixed start and read as "no information", so the budget could only
shrink.
- taint.sc streams each answer's own cost (`ms`); the backend carries it as a
reserved `__timing__` list through shards, partitions and reuse.
- The sizer budgets predicted seconds from per-family seconds-per-visit rates
learned from those costs, and measures the fixed start as the wall time the
answers do not explain (median), instead of assuming it.
- A kill names its culprit: the first unanswered id in request order. The ids
behind it never started and are re-queued at once; the culprit is asked
alone after the rest. One that still fails alone after more than a
portion's target is reported as `query_too_expensive`, apart from
`query_failed`.
- Portions grow id by id from the queue head, and a single-portion scan now
goes through the queue too, so a kill there re-asks its remainder.
- Fix: the reuse wrapper wrapped only `run_batch`, so since 7.8 every
portioned query bypassed the graph-reuse cache and its source-root
normalization. `run_batch_once` is wrapped too.

run_batch_once was wired on the disposable and sharded paths but not the partitioned one -- and a
multi-language repository, which every WordPress plugin is, builds through the partitioned graph. So
the portioner fell back to run_batch there, whose internal split-retry folded into the time it
measured: a portion read 956 s and collapsed the sizer, exactly as before the single-attempt fix.
The fix had no effect on the one subject it was written for.
PartitionGraph now has run_batch_once, dispatching to each sub-graph the same way run_batch does --
the routing is factored into one _dispatch method that takes the per-graph method name. Sub-graphs
are built through the disposable path and already carry run_batch_once.
The lesson, again: a capability added at one construction site is not added at the others. There are
three that build a queryable graph -- disposable, sharded, partitioned -- and the one that mattered
for the measurement was the one missed.
1,424 tests pass, nineteen skipped.

A missing JavaScript file cannot make a PHP answer wrong. A census gap now carries the partition it
was raised for, and reaches only that partition questions. On the measured plugin four JavaScript
files -- a webpack build output, a minified select2, a build config and one source file -- had taken
the admissibility of 4,425 PHP regions with them.
Two controls exercise the real boundaries rather than injecting a reason, and both were confirmed to
FAIL with the old classification restored, so they guard what they claim to.
And the rule is now in the design, because this was the fifth instance found and fixed one at a time.
Two invariants, eleven instances between them:
A degradation is owned by the narrowest scope that caused it. Vendor exclusion as a global veto,
line ambiguity inherited by every question, an empty scope blocking a sibling comparison, a language
boundary demoting every answer, a census gap demoting every answer. The fourth and fifth cost the
declared v0.1 target its entire admissibility, and neither passing subject could reveal it because
both hold one language.
A token matches the thing it names, not text that contains it. gets inside fgets, resolve inside
resolveUrl, user inside users, a sink word inside a comment, a dotted setting on its last segment,
a flow query reading the receiver.
Each carries a review test: a new degradation must state the scope it reaches and justify demoting
that far, and a text match must be bounded AND confined to the part of the node that names the callee.
1,419 tests pass, eighteen skipped.
