The job's own src (test/test_synth_soname_survives_redeclaration.pas, 4 file(s)) is NOT used here on purpose: it is what the job compiles, not what broke, and guessing a lane from it is what sent three reds in one job to the wrong lane. This is a FALLBACK, not a finding — nothing says the defect is Track T's. Re-lane it before working it.

origin/master has advanced 1 commit(s) since this sha. Re-verify at current HEAD before acting — the callback is tagged to the sha that was tested, which may no longer be the state of the tree.

Range

The named sha 4fbed6c4157e CANNOT be the cause — it touches no buildable file (docs / tickets / tstate only). It is the sha that was TESTED, i.e. the upper bound of an untested range; the cause is somewhere below it.

bad 4fbed6c4157e, last good 7f86a12a6628, 4 commit(s) in range — the watcher narrows this by idle bisect; check tstate/TSTATE.md for the current range.

FAIL: synthclob26 has no libc.so.6 DT_NEEDED. memcmp is supposed to be a dynamic import here, so this binary is not exercising the path — with it inert the libsynthclob.so row above cannot fail and its silence means nothing

Stub ticket: signal only. Track T agent (face 2) enriches or a dev track takes it from the repro line.

Log

• 2026-09-18 — auto-closed by the borg watcher: test-core#src:test/test_synth_soname_survives_redeclaration.pas passes at 578ca3e81d91 (tier native); it was red at 4fbed6c4157e. Reopening is by a fresh NEW-RED stub, since a second red is a second finding with its own range.
