Understanding
PLF-8307 passed 1585 Core tests and governance but publication stopped with
blocking_delta=1. Exact replay proved the added contradiction joins a full
documentation sentence at lines 32-33 with a shorter NL projection at line 32
from the same ticket README. The shorter projection ends before “not as
Sprawdzanie”, so it is not independent contrary evidence.
Execution plan
- Commit this source-bounded plan before implementation.
- Add a linker regression for overlapping same-source excerpts while retaining
a distinct-source contradiction control.
- Apply the narrow source-overlap guard and run focused/full verification.
- Replay the exact PLF-8307 patch, publish through Validator, then repin the
coding-agent runtime and retry the governed Core ticket.
Actual changes
- Added a source-overlap guard that normalizes paths and suppresses only a
contradiction between records whose source line ranges overlap.
- Added a regression reproducing the PLF-8307 document/NL projection and a
negative control proving that an independent source can still contradict it.
- Replayed the exact PLF-8307 candidate: the base and workspace each retain one
pre-existing blocking diagnostic, so the candidate adds no blocking delta.
- Passed the focused tests, full repository verification, Docker smoke,
governance and whitespace gates.
- Ticket-094 later restored this intent projection to the exact PR #103 scope
and appended PR #110 as a historical scope mismatch. That note does not
revoke PR #110’s technical checks or pretend its authorization was valid.
Blockers
- None. Validator approved exact HEAD
a37f4020 for ticket-088; protected
PR #103 merged as 89e72ce and the implementation branch was deleted.
