Cycle: v3/qdb_memory_audit Debug mode: enabled Entry: 2026-10-30 UTC, Step 1 completed audit handoff

Necessary/useful instructions

Source: RAILSPIKE.md, Choose the execution mode; Step 1, review guardrails. Observation: Kept an explicitly requested audit separate from implementation. Findings and reproductions are complete without waiting for an implementation approval. Suggestion: Retain the distinction between investigation authorization and remediation approval.

Source: Step 1, estimates and study recovery; host P2 enrollment. Observation: Frozen R1 hashes were available. The intake records source exposure instead of inventing a pristine initial estimate. Suggestion: Retain explicit missing-checkpoint handling.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: RAILSPIKE.md, Step 4 branch/stage gates and concept inventory delivery. Observation: No production implementation occurred. Step 4 organization, stages and application acceptance do not apply to this audit handoff. Suggestion: Keep these scoped to later implementation; proposed missing concept entries remain proposals.

Uncertain assessments

Source: Step 1, one-page comparison deliverable. Observation: The comparison fits a short assessment, while ten findings and executable reproductions require a linked evidence artifact. Suggestion: Clarify that an audit may attach detailed evidence without expanding the assessment into an implementation plan.

Entry: 2026-10-30 UTC, Step 1 revision after task-update request Revision: Clarifies the original audit handoff; does not erase its findings or approve advancement.

Necessary/useful instructions

Source: Step 1, review and revision; RAILSPIKE.md, experimental effort estimation. Observation: Revised an inconsistent 128 MiB acceptance statement while preserving historical measurements, proposed-target status and the unchanged audit-only estimate. Distinguished a completed diagnosis from unperformed remediation acceptance. Suggestion: Retain the requirement to update the current assessment instead of leaving conflicting recommendations in appended notes.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: Step 4, implementation verification. Observation: This turn updates task documentation only. No runtime checks or application changes were made. Suggestion: Keep later implementation approvals separate from this documentation correction.

Uncertain assessments

Source: Step 1, high-level assessment boundary. Observation: Detailed proposed acceptance cases belong in the linked audit evidence; the assessment carries only the summarized targets and ownership boundary. Suggestion: Preserve this separation when defining the later executable test plan.

Entry: 2026-10-30 UTC, Step 1 option-selection revision Revision: Option A replaces the prior recommendation prospectively; executed probes and earlier estimates remain recorded.

Necessary/useful instructions

Source: Step 1, review and revision; experimental effort-estimation history. Observation: Recorded the selected source-only scope without deleting evidence gathered before selection. Moved proposed broader capacity work to its own requested assessment and preserved the original alternative/whole-cycle scores. Suggestion: Retain the distinction between selected future scope and work already performed.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: Step 2 advancement and Step 4 execution. Observation: Selecting an option and requesting another plan did not supply Approved Step 1 or implementation approval. Suggestion: Keep normal gates intact.

Uncertain assessments

Source: Step 1, Understood Intent. Observation: Two nearby assessments have A/C alternatives. The latest discussion names the QDB memory audit; the interpretation was stated in commentary and recorded explicitly in both plans. Suggestion: Preserve parent links so a later scope correction is straightforward.

Entry: 2026-10-30 UTC, Step 2 handoff

Necessary/useful instructions

Source: Step 2, delivery scope and known environment. Observation: Made the selected source audit explicitly documentation-only, retained the QDB PHP 8.3 recovery evidence gap and separated completed local diagnosis from undelivered fixes. Suggestion: Retain these boundaries to prevent an audit approval from becoming an unreviewed runtime rewrite.

Source: Step 2, shared components and completion boundary. Observation: Named relevant entry-point families and required a consistent finding inventory rather than another measurement campaign. Suggestion: Retain caller-path and evidence-label checks for documentation-only audits.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: Step 2, new UI/API component design. Observation: Existing components are inspected unchanged; no UI or API design is needed. Suggestion: Keep the inventory requirement but omit new-component implementation work for this scope.

Uncertain assessments

Source: Approval scope recovery. Observation: The initial commentary interpreted approval as applying to the expansion. The user corrected it before any expansion Step 2 artifact or approval record was written. This handoff records only the clarified QDB approval. Suggestion: Preserve explicit plan names in future approval handoffs when several assessments are active.

Entry: 2026-10-30 UTC, Step 3 handoff

Necessary/useful instructions

Source: Step 3 Before/Do/After, completion contract and documentation-only scope. Observation: Three stages finish the approved source inventory, operator guidance and document handoff without introducing runtime fixes or new benchmarks. Manual incident walkthroughs preserve the known-host limitation. Suggestion: Retain scope checks and the distinction between documented recovery guidance and live verification.

Source: RAILSPIKE.md, planning commit and organization rules. Observation: The working tree also contains two unapproved assessments and a historical executable probe. The plan excludes unrelated changes, archives probe source as text, and checks references against the committed tree. Suggestion: Retain explicit staged-file checks for mixed planning workspaces.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: Step 3, database/signature and runtime verification planning. Observation: The approved artifact is documentation-only; schema, API, UI and runtime test changes are inapplicable. Suggestion: Keep their exclusion explicit rather than manufacturing application work.

Uncertain assessments

Source: Step 3, atomic stage sizing. Observation: Findings already exist, so expected edits are concise reconciliations. Significant intervening source changes could require more review. Suggestion: Recheck stage size before execution and preserve the approved document boundary.

Entry: 2026-10-30 UTC, Step 4 completed handoff Commits: Planning 6a824006; Stage 1 4000874a; Stage 2 7ac4ee39; Stage 3 46e85b70. This diagnostic is a separate log-only handoff commit.

Necessary/useful instructions

Source: Step 4 Before, planning-commit gate and approved scope. Observation: Kept the summary out of the planning commit, preserved the approved documentation-only boundary and excluded two unapproved plans plus the executable probe from all cycle commits. Suggestion: Retain explicit staged-scope checks in mixed planning workspaces.

Source: Step 4 Do/After, stage-boundary verification and known-environment limits. Observation: Each stage has a summary-bearing commit and document/evidence checks. The operator guide maps both original failures and lock contention without claiming production recovery. Historical probes remain distinct from new verification. Suggestion: Retain separate document-integrity and runtime/host evidence statuses.

Source: Experimental effort estimation, closeout. Observation: Preserved original estimates, reaffirmed the 0.40 total, recorded separate stage/cycle retrospectives and left maintainer acceptance pending. Suggestion: Retain historical scope/exposure and acceptance separation.

Redundant/unnecessary instructions

No supported findings.

Inapplicable instructions

Source: Runtime/UI/migration/deployment verification gates. Observation: No executable application behavior changed; no new runtime tests, host workload or deployment was run. Source-path, finding-field, archive-byte, link, staged-file and whitespace checks supplied the applicable evidence. Suggestion: Continue labeling those runtime gates inapplicable rather than claiming a test-suite pass.

Uncertain assessments

Source: Link/path verification and artifact organization. Observation: Working-directory links initially resolved to other unapproved artifacts, but would fail in the committed tree. Pending plain-text references and selective ledger staging were needed for an independently reviewable branch. Suggestion: Explicitly recommend committed-tree link checks where unrelated untracked plans coexist.

Final boundary: Documentation contract complete; application changes/dependency delta zero. QDB host recovery, lower memory-budget acceptance, merge/push/deployment and maintainer acceptance remain unverified or pending as stated. Other draft plans, their ledger entries and the unchanged probe remain outside this branch's committed scope.
