Collapse the four definitions of "one log line" into LogLine (timestamp,
level, source, text) with a single renderer and parser. agent.log lines
now carry the uniform prefix, absorbing the ssxng: event marker into the
source column; legacy lines degrade to raw display without rewriting.
Level detection moves into the row model with a classic three-level
taxonomy whose unified-log projection stays unchanged.
The diagnostics log view merges GUI events and the agent.log tail through
DiagnosticLogIntake into one time-ordered list with level and source
filters; the tail window logic moves into the intake and blank lines are
kept for raw fidelity. The report whitelist projection and unified-log
routing are unchanged.
Add the SSXNG_SYSTEM_LOG=0 test seam: RuntimeLog.emit and the sslocal
unified-log destination skip their os.Logger writes when it is set,
while stderr lines and the event sink are unaffected. Test execution
no longer floods the unified log store (a full validate run previously
recorded 795 entries under the shared subsystem, 743 from xctest and
52 from test-spawned agents).
The switch is injected by the schemes' test actions only (Run/Profile
keep system logging so debugging from Xcode still shows it), and set
explicitly in the fixtures that spawn the agent/sslocal processes,
including the fixture that strips inherited SSXNG_* path seams. The
main scheme is now declared explicitly to keep the variable out of the
Launch/Profile actions. Document the seam in ADR-0045.
Separate Agent supervision from sslocal input and preserve the latest intent after deployment failure. Persist failure barriers, serialize publication and retirement, and verify reload and single-instance behavior with real processes.
