Outcome: none established

No consequential residual defect was established as a result of the investigated execution failures. The evidence shows meaningful recovery: corrected source paths, equivalent direct reads, repaired quotation attribution, corrected validation invocations, and a later substantive profile correction. This is not a correctness certificate.

Residual findings

None established.

The investigation selected three consequential claims from the accepted synthesis/profile and traced their dependencies backward.

1. Fallback compaction implements trace-fed retained context

Accepted passage: “Fallback compaction automatically turns recorded work and prior bootstrap material into a summary, persists it, clears the native session ID and supplies that seed to a later ordinary turn without native context” (artifact/synthesis.md:42). The profile emits trace_learning: yes, with wired basis, for that localized mechanism (artifact/memory-profile.md:945–966).

Suspected failure dependency: The memory worker’s failed chained search could have prevented inspection of delegation/context mechanisms or alternative memory paths. At trace line 1521, call_OmaTjbf… failed because agent-skills/orx-delegation/SKILL.md did not exist; the final hooks/memory search was consequently skipped.

Recovery checked: The worker listed the actual skill directories and reran the skipped hooks/memory search (call_960w…, result at line 1587), then successfully read agent-skills/orx-agent-delegation/SKILL.md (call_tiWL…, result at line 1614). More importantly, the failed search did not prevent the compaction evidence reads: the worker had already inspected the compaction implementation and subsequently inspected branch/context consumers. Independent report verification reread the compaction implementation and ordinary composition (6dc3add…, calls beginning at lines 1637–1640).

Direct challenge: Frozen src/local/chat/mod.rs:1681–1762 implements the native/fallback split, nonempty model summary, bootstrap persistence, and native-ID clearing. Lines 1296–1309 gate bootstrap delivery on absence of a native session ID. The accepted text distinguishes this from opaque native compaction and does not claim observed improvement (artifact/synthesis.md:42–44; artifact/memory-profile.md:1126).

The failure therefore has no supported connection to a surviving false positive on this selected classification. Untraced alternatives remain coverage limits, not evidence against this localized implemented chain.

2. Permission guarantees are route-specific, not system-wide read-only guarantees

Accepted passage: Claude bridge requests receive token/busy-turn checks; Codex Plan includes workspace-write; operator shell is a separate mutation path; neither Plan nor a private worktree guarantees system-wide read-only behavior (artifact/synthesis.md:22).

Suspected failure dependency: Two runtime discovery commands used nonexistent paths. The first failed on src/local/chat/host.rs; its chained wc was skipped. The second stopped at nonexistent directory src/commands/exp, skipping its subsequent route search.

Recovery checked: The worker located the actual monolithic chat implementation and experiment file (call_51hz…, trace lines 712–716), then successfully read permission handling and shell execution (call_0CZY…, result line 872; call_zeF7…, result line 874). It also read the Codex policy mapping. Independent verification inspected token, busy-turn, bypass, plan-policy, human-review, shell, and Codex branches (artifact/report-verification.md:20; corresponding source-read calls in launch 6dc3add… at lines 2401–2403).

Direct challenge: src/local/chat/mod.rs:3456–3534 contains token and busy-turn checks plus bypass/plan/review branches; :1814–1896 launches shell commands without a model permission-mode check. src/local/harness/codex.rs:1342–1365 explicitly maps Plan to workspace-write. These support the accepted qualifications rather than a stronger isolation guarantee.

No load-bearing permission premise was shown to remain dependent on the failed paths.

3. Chart validation is implemented but does not establish scientific truth

Accepted passage: “The chart helper does enforce numerical/schema conditions before its own new write, but fabricated finite values can pass and arbitrary writers bypass it” (artifact/synthesis.md:38).

Suspected failure dependency: The epistemic worker’s first chained discovery command stopped at nonexistent src/local/harness/mcp_gate.rs, preventing chart and project searches. The corrected command reached the chart search but then returned 1 because the project search found no matches, skipping the invocation-related search.

Recovery checked: The next batch successfully read the complete chart helper (call_DHAt…, trace lines 1530/1535), invocation gate and invocation helper (call_mCNY…, result 1539; call_bV5X…, result 1536). Earlier reads of experiment/tree operations had already provided evidence relevant to the skipped project search. Independent verification reread the chart helper (6dc3add…, call at line 1668).

Direct challenge: agent-skills/orx-figures/assets/orx_chart.py:10–49 checks structural/numerical conditions; :52–57 validates and serializes before writing. There is no measurement-provenance check in that helper. The accepted passage confines enforcement to this helper and does not equate structural validity with scientific acceptance.

The source-read failures were recovered for this claim; the accepted qualification survives the challenge.

Incident dispositions

Incident Disposition Decisive evidence
Epistemic, scanner trace line 1380, call_b5vn…: nonexistent MCP-gate path recovered The error’s own inventory supplied src/commands/mcp_gate.rs. Corrected search at lines 1502–1506 reached that file and chart checks; complete chart read followed at 1530–1535.
Epistemic, line 1506, call_2yO8…: search exit 1 recovered; no-match itself was expected-nonzero Original event confirms MCP and chart searches succeeded; project search produced no match, so && skipped invocation inspection. Direct invocation/gate reads at 1531–1539 fulfilled that skipped purpose. It was not treated as an entirely harmless successful chain.
Epistemic, line 15089, call_tGiG…: ambiguous quotation recovered Complete diagnostic identifies three occurrences of a 404 branch. Edit at lines 15239–15240 selected src/client.rs:915–917; accepted artifact/epistemic.md:351 retains that attribution. Frozen src/client.rs:902–927 confirms the selected occurrence belongs to paper-markdown retrieval. The quotation repair does not weaken that underlying claim.
Epistemic, line 15411, call_spJ7…: wrong artifact path recovered Correct-path validation ran separately at 15608 and returned exit 0 at 15611. This establishes execution of the intended structural check, not semantic correctness.
Memory, line 1521, call_OmaT…: nonexistent delegation skill path recovered Directory discovery, rerun of skipped hooks/memory search, and successful equivalent skill read at 1583–1614.
Memory, line 11103, call_9pdE…: validator rejected “Validation: pending” recovered Later check returned exit 0 at 11432; accepted artifact/memory.md:354 replaces the pending marker and explicitly limits what validation establishes. No content conclusion was shown to depend on that marker.
Memory-profile, launch f6cf629…, line 6691, call_EMxm…: wrong candidate path recovered Correct-path check returned exit 0 at 6893; a further check returned exit 0 at 7700. The accepted profile is a later revised attempt, not merely this initially validated draft.
Runtime, lines 565 and 639, call_kLZd… / call_OOmv…: wrong host/file-layout assumptions recovered Actual file locations and route discovery at 712–716; successful direct reads of consequential permission, shell, experiment and wake-up paths followed.
Additional masked error: runtime line 1015, call_MaMe… recovered rg src/local/run_wake* reported no such file, but subsequent commands made the combined result exit 0. Later discovery located wake-up functions in src/local/chat/mod.rs, followed by a successful read at 1365–1372. Thus shell success did mask an error, but did not leave that mechanism uninspected.

Substantive correction preserved

The first profile verification identified an unsupported emitted ranking value: archive visibility and changed comparison organization did not establish a relative-priority mechanism (calls/launches/b147058…/inputs/refusal.md:7). The revised accepted profile removes that finding, uses not-determinable, and explains the missing consumer/effect (artifact/memory-profile.md:465–476, :1130).

This was a successful semantic correction, not evidence that validation alone ensured adequacy. Its causal connection to the earlier wrong-path validator invocation is not established.

Unresolved consequential concerns

None established within the selected dependency chains. The accepted report’s catalog-screening and compute/CUSTOM.md inventory omissions are explicitly preserved (artifact/synthesis.md:48, limitations table). Their causal connection to the investigated failures was not demonstrated; they are not attributed to those failures here.

Coverage and limits

  • Read the input map, full scanner report and attempt inventory, accepted synthesis, and complete memory profile, recovering its truncated ending.
  • Examined all nine scanner-recorded failed executions, plus the masked runtime search error above.
  • Inspected original process events and recovery operations for epistemic, memory, runtime, initial/revised profile, and report-verification launches. Inspected tool-call inventories for both profile-verification attempts and the substantive correction handoff.
  • Read the exact epistemic, memory and runtime prompts and their frozen job instructions. Challenged selected claims against frozen source without execution.
  • Did not independently trace every event in boundary, reconciliation, workflow, synthesis or synthesis-verification launches, nor audit all source, profile axes, receipt/publication mechanics, or retained outputs.
  • Scanner excerpts were not used as proof of non-recovery. Truncated diagnostic excerpts relevant to the investigated incidents were resolved through original events. A bounded trace-index output was supplemented for the omitted epistemic range.
  • Used 27 tool calls, all for read-only inspection or in-memory parsing. No validation reruns, worker launches, network access, target execution or file mutation occurred.

The supported outcome is limited: these failures did not establish a consequential surviving defect in the selected accepted claims. It does not establish that every accepted conclusion is correct or that unexamined logs contain no other failures.
