Retain inspection file owners before a target lease exists and gate replacement on cleanup. Reuse the streaming string inventory owner and the same installation adapter in native profiling. Validate 80 related tests, real SSH value/source parity in both MCP adapters, injected descriptor/native cleanup retries, zlib SDK immutability and native profiling. Keep historical model costs pinned to their measured runtime.

# Main refresh and shared-owner compatibility
|
|
|
|
The experiment was refreshed from main
|
|
`60bf1024592888b5efb78f9c9458b4633da298bd` at merge commit `8e0aa73db`.
|
|
This updates only the experimental branch; no PR or integration merge is intended.
|
|
The [OpenSSH model comparison](ssh-warning-study.md) remains a historical result
|
|
at frozen runtime `09677946c`. Its model runs were not repeated on this new
|
|
compiled runtime, and its costs must not be relabeled as current measurements.
|
|
|
|
## Producing boundaries
|
|
|
|
Main now requires caller-owned file resources when inspecting Kuna. The session
|
|
owns an `ArtifactResourceScope` before attempting an open, including when no
|
|
target lease is established. A failed descriptor close keeps its exact owner;
|
|
close retries it, and another open cannot acquire a replacement until cleanup
|
|
succeeds. The shared native-installation adapter reuses main's error projection
|
|
and cleanup leases. The diagnostic native profiler uses the same adapter and
|
|
retains its own file scope through final cleanup. No fallback installation
|
|
parser or parallel resource manager was added.
|
|
|
|
Main also replaced the whole-string inventory parser with
|
|
`KunaStringInventoryReader`. The experiment feeds its bounded retained source
|
|
through that owner and freezes the validated inventory once. The underlying
|
|
capture still retains complete source Evidence; this adapter update does not
|
|
establish streaming native capture or a new analysis speedup.
|
|
|
|
The initial source test invocation failed to load the removed string-parser
|
|
export. After updating that boundary, 65 Code Mode/API tests and the 15 shared
|
|
atomic-fact tests pass. The two new cases verify failed-open cleanup and
|
|
replacement admission. Focused lint reports no warnings, and formatting passes.
|
|
|
|
## Real artifact checks
|
|
|
|
The unchanged preserved `a9ca8a8a...` experimental engine is used throughout.
|
|
Both actual MCP adapters repeat the stripped OpenSSH value task, checking all
|
|
250 selected SSA versions and 369 operand occurrences against the earlier
|
|
complete native graph. Both caller/emitter function records equal the prior
|
|
goldens, including C, calls and graph fields. Each route executes fifteen MCP
|
|
requests; these are verification scripts, not new model trials.
|
|
|
|
A first Code Mode verifier attempt omitted its required evaluator Evidence
|
|
directory. Its reads succeeded but its later producer comparison failed. That
|
|
attempt remains recorded; the verifier now validates the required setting
|
|
before analysis, and both complete reruns pass with separate source directories.
|
|
|
|
Linux MCP failure injection rejects two close attempts for the actual engine
|
|
fingerprint descriptor. Procfs confirms the same descriptor remains open after
|
|
the failed initial open and blocked replacement, then disappears after the
|
|
successful close retry. The lease stays null until a later open succeeds.
|
|
Both adapters also repeat the existing native-close failure/retry scenario.
|
|
These failures are injected, not observed OS or engine cleanup incidents.
|
|
|
|
Real zlib SDK reads preserve cached strings, aliases and source metadata against
|
|
caller mutation and verify the complete Evidence digest. SDK cleanup/replacement
|
|
retry checks pass on SSH. The native profiler completes two zlib `inflateReset`
|
|
captures at `0xbf00` with equal function records; internal timing is disabled.
|
|
The generated traditional baseline still contains exactly the sixteen declared
|
|
native/session/view tools, matching the earlier corrected manifest. Declared
|
|
catalog coverage does not prove every operation's live behavior.

## Executed resource costs
|
|
|
|
| Scope | Family wall s | Family CPU s | Kernel peak MiB |
|
|
| ---------------------------------- | ------------: | -----------: | --------------: |
|
|
| Locked dependency install | 20.462 | 19.525 | 1,601.2 |
|
|
| Runtime and packaged-skill build | 85.441 | 84.797 | 2,730.4 |
|
|
| Code Mode/API tests, 65 | 4.447 | 4.234 | 87.5 |
|
|
| Shared atomic-fact tests, 15 | 0.623 | 0.439 | 43.9 |
|
|
| SSH value queries, Code Mode | 9.382 | 9.146 | 336.5 |
|
|
| SSH value queries, direct | 8.976 | 8.759 | 346.5 |
|
|
| Engine descriptor retry, Code Mode | 2.036 | 1.769 | 198.0 |
|
|
| Engine descriptor retry, direct | 1.935 | 1.728 | 184.8 |
|
|
| Native close retry, Code Mode | 1.831 | 1.650 | 188.9 |
|
|
| Native close retry, direct | 1.744 | 1.559 | 182.4 |
|
|
| SDK inventory immutability | 1.530 | 1.285 | 123.8 |
|
|
| SDK cleanup/replacement retry | 1.831 | 1.602 | 128.1 |
|
|
| Native profiler, two captures | 1.931 | 1.683 | 110.2 |
|
|
| Actual baseline catalog generation | 3.943 | 3.727 | 438.2 |
|
|
|
|
All use one CPU, 4 GiB hard / 3 GiB early-stop memory bounds, OOM/kill 0 and
|
|
verified payload cleanup. Kernel process-family peaks include charged file
|
|
cache, not RSS. Source receipts remain under `.cache/atomic-codemode/main-refresh-*`.
|
|
The unsuccessful initial test/load attempt costs 3.138 wall / 2.942 CPU seconds,
|
|
79.8 MiB; the incomplete verifier attempt costs 9.181 / 8.941 seconds, 353.2 MiB.
|
|
Both also have OOM 0 and verified cleanup.
|
|
|
|
The successful query verifiers retain separate fresh leases/native caches:
|
|
|
|
| Phase | Code Mode wall / CPU s | Direct wall / CPU s |
|
|
| ------------------------------------------- | ---------------------: | ------------------: |
|
|
| Two fresh native captures | 7.354 / 7.346 | 7.139 / 7.087 |
|
|
| First indexed task, all 250 values/369 uses | 0.233 / 0.234 | 0.167 / 0.168 |
|
|
| Same-lease selected one-value/use read | 0.008 / 0.009 | 0.008 / 0.006 |
|
|
|
|
The last two rows complete different tasks; they do not measure a warm-task
|
|
speedup. The native profiler's fresh/second-process captures take 643.1/453.9 ms,
|
|
with private native cache reuse, without separate CPU or peak measurements.
|
|
The family table includes startup, capture, reads and cleanup. Cumulative peaks
|
|
do not isolate warm memory; OS caches and host contention are uncontrolled.
|
|
No new real-agent token measurement was performed in this refresh. Full
|
|
repository/native test suites, other providers, and new real-agent comparisons
|
|
on this refreshed runtime remain unverified.
