# Step-Not-Found Evidence Integrity Audit

Date: 2026-02-25
Step: `gate-remediation-step-not-found.audit-current-state`

## Scope

Read-only forensic audit of prior follow-up claims related to step-not-found safeguard and evidence integrity.

Primary targets audited from `plan.yaml` evidence:

- `legacy-logs-cleanup-followup.reconcile-step-id-mapping`
- `legacy-logs-cleanup-followup.harden-step-not-found-handling`

## Commit Existence Checks

Command:

```bash
for h in 107132024ef0d8e0bb02911fcb1c7af1b44dfb60 5e9b8aa 382f26f a0eb93a e8f9d1c b9919ca a7d7fe0 5fb8be7; do
  if git rev-parse --verify "$h^{commit}" >/dev/null 2>&1; then
    printf "%s EXISTS\n" "$h"
  else
    printf "%s MISSING\n" "$h"
  fi
done
```

Observed output:

```text
107132024ef0d8e0bb02911fcb1c7af1b44dfb60 EXISTS
5e9b8aa MISSING
382f26f MISSING
a0eb93a MISSING
e8f9d1c MISSING
b9919ca MISSING
a7d7fe0 MISSING
5fb8be7 MISSING
```

Additional confirmation for surviving commit:

```bash
git show --no-patch --oneline 107132024ef0d8e0bb02911fcb1c7af1b44dfb60
git show --name-only --pretty=format:'%H %s' 107132024ef0d8e0bb02911fcb1c7af1b44dfb60
```

Observed output:

```text
1071320 docs: add legacy-logs-cleanup ID reconciliation note

107132024ef0d8e0bb02911fcb1c7af1b44dfb60 docs: add legacy-logs-cleanup ID reconciliation note
docs/ops/legacy-logs-cleanup-reconciliation.md
```

## File Existence and Tracking Checks

Command:

```bash
for f in docs/ops/legacy-logs-cleanup-reconciliation.md src/lattice/shell/orchestration.py src/lattice/shell/error_handler.py src/lattice/shell/reconciliation.py tests/shell/test_orchestration_step_not_found.py tests/shell/test_error_handler.py tests/shell/test_step_reconciler.py docs/orchestration.md; do
  if [ -e "$f" ]; then
    if git ls-files --error-unmatch "$f" >/dev/null 2>&1; then
      printf "%s EXISTS_TRACKED\n" "$f"
    else
      printf "%s EXISTS_UNTRACKED\n" "$f"
    fi
  else
    printf "%s MISSING\n" "$f"
  fi
done
```

Observed output:

```text
docs/ops/legacy-logs-cleanup-reconciliation.md EXISTS_TRACKED
src/lattice/shell/orchestration.py EXISTS_TRACKED
src/lattice/shell/error_handler.py MISSING
src/lattice/shell/reconciliation.py MISSING
tests/shell/test_orchestration_step_not_found.py MISSING
tests/shell/test_error_handler.py MISSING
tests/shell/test_step_reconciler.py MISSING
docs/orchestration.md MISSING
```

History check for missing files:

```bash
for f in src/lattice/shell/error_handler.py src/lattice/shell/reconciliation.py tests/shell/test_orchestration_step_not_found.py tests/shell/test_error_handler.py tests/shell/test_step_reconciler.py docs/orchestration.md; do
  c=$(git log --oneline --all -n 1 -- "$f")
  if [ -n "$c" ]; then
    printf "%s HISTORY %s\n" "$f" "$c"
  else
    printf "%s NEVER_TRACKED\n" "$f"
  fi
done
```

Observed output:

```text
src/lattice/shell/error_handler.py NEVER_TRACKED
src/lattice/shell/reconciliation.py NEVER_TRACKED
tests/shell/test_orchestration_step_not_found.py NEVER_TRACKED
tests/shell/test_error_handler.py NEVER_TRACKED
tests/shell/test_step_reconciler.py NEVER_TRACKED
docs/orchestration.md NEVER_TRACKED
```

## Cross-Check: Evidence vs Observable State

- The reconciliation-step commit claim (`107132024ef0d8e0bb02911fcb1c7af1b44dfb60`) is valid and maps to a docs-only change.
- The harden-step claim includes 7 commit hashes that do not resolve to commits in this repository.
- The harden-step claim lists 8 changed files; only 1 currently exists/tracked (`src/lattice/shell/orchestration.py`).
- 6 listed files have no git history (`NEVER_TRACKED`) and 1 listed doc file is missing and never tracked.

## Findings

- Phantom commits:
  - `5e9b8aa`
  - `382f26f`
  - `a0eb93a`
  - `e8f9d1c`
  - `b9919ca`
  - `a7d7fe0`
  - `5fb8be7`
- Phantom files:
  - `src/lattice/shell/error_handler.py`
  - `src/lattice/shell/reconciliation.py`
  - `tests/shell/test_orchestration_step_not_found.py`
  - `tests/shell/test_error_handler.py`
  - `tests/shell/test_step_reconciler.py`
  - `docs/orchestration.md`

## Integrity Verdict

`INTEGRITY_BREACH`

Rationale: Prior follow-up evidence for harden-step-not-found includes non-resolving commit references and multiple file claims not present in repository history or current filesystem.
