# T-194: Research Persistence Experiment Specification

**Date:** 2026-02-19
**Participants:** Human + Claude (dialogue)
**Phase:** 0c (Experiment design)
**Purpose:** Design, build, and validate controls for research persistence — using T-194 itself as the test subject.

## Background

Seven existing controls for research persistence all failed during T-194 inception (see `T-194-research-persistence-failure-analysis.md`). Root cause: all controls are post-hoc, advisory, scope-limited, or unused. No structural enforcement exists for main-thread conversation capture.

## ISO 27001 Design Principle

Every control is designed with four layers simultaneously:

```
Risk → Control Design → OE Test → Audit
```

We define all four BEFORE building. No more "build control, hope it works."

## Risk Statement

**R-001: Research Loss**
- **Description:** Research generated in human-agent conversation (decisions, discoveries, analysis, options evaluated) is not persisted to durable artifacts. Lost at context compaction or session end.
- **Likelihood:** High — observed in T-194, T-151, T-174, T-073 (multiple incidents across project history)
- **Impact:** High — lost decisions are re-debated, lost analysis is re-done, lost discoveries are never re-discovered
- **Treatment:** Mitigate via three complementary controls (D, F, B) targeting different failure modes

## Experiment Design

### Three Controls to Build and Test

---

### Control C-001: Live Document Pattern

**ISO Level:** Preventive (reduces likelihood)

**Design:**
When starting work on an inception task, the agent creates a research artifact file in `docs/reports/T-XXX-*.md` BEFORE conducting research. The file is updated incrementally as the conversation produces findings. Each phase or major dialogue segment gets committed.

**Expected behavior:**
- Research file created within first 5 tool calls of inception work
- File updated at least once per 30 minutes of active inception dialogue
- File committed at least once per session on the task

**Implementation:**
- Add rule to CLAUDE.md under "Inception Discipline": "When starting work on an inception task, create the research artifact file in docs/reports/ FIRST (even as skeleton), then fill incrementally. Commit after each dialogue segment."
- This is a behavioral rule, not a hook — intentionally. We're testing whether explicit rules with OE monitoring outperform implicit rules without it.

**OE Test (Approach 1 — outcome):**
```bash
# For each active inception task with started-work status:
# Check if docs/reports/T-XXX-* exists
# Check if it was modified within last 24 hours (if task was worked on)
for task in .tasks/active/T-*.md; do
    workflow=$(grep '^workflow_type:' "$task" | cut -d: -f2 | tr -d ' ')
    status=$(grep '^status:' "$task" | cut -d: -f2 | tr -d ' ')
    [ "$workflow" != "inception" ] && continue
    [ "$status" != "started-work" ] && continue
    task_id=$(grep '^id:' "$task" | cut -d: -f2 | tr -d ' ')
    artifact=$(find docs/reports/ -name "${task_id}-*" -type f 2>/dev/null | head -1)
    if [ -z "$artifact" ]; then
        echo "FAIL: Inception $task_id has no research artifact"
    fi
done
```

**OE Test (Approach 4 — mechanism):**
```bash
# Check task Updates section for research artifact entries
# An inception task worked on should have an Update referencing docs/reports/
for task in .tasks/active/T-*.md; do
    workflow=$(grep '^workflow_type:' "$task" | cut -d: -f2 | tr -d ' ')
    status=$(grep '^status:' "$task" | cut -d: -f2 | tr -d ' ')
    [ "$workflow" != "inception" ] && continue
    [ "$status" != "started-work" ] && continue
    task_id=$(grep '^id:' "$task" | cut -d: -f2 | tr -d ' ')
    artifact_ref=$(grep -c 'docs/reports/' "$task" 2>/dev/null || true)
    if [ "$artifact_ref" -eq 0 ]; then
        echo "WARN: Inception $task_id Updates section doesn't reference any artifact"
    fi
done
```

**Audit:** Cron job runs both OE tests every 30 minutes as part of the existing quality section. Results appear in cron audit YAML.

---

### Control C-002: Inception Commit Gate

**ISO Level:** Detective (detects non-compliance after the fact)

**Design:**
The `commit-msg` hook, when processing a commit that references an inception task, checks whether the staged diff includes a file in `docs/reports/`. If not, it issues a WARNING (not a block). The warning is logged.

**Expected behavior:**
- Every inception commit after the first one includes a docs/reports/ file change
- Warnings are logged to `.context/working/.inception-research-warnings`
- Zero warnings after the control is adopted = control is working

**Implementation:**
Modify `.git/hooks/commit-msg` to add after the existing inception gate logic:

```bash
# Research artifact check for inception commits
if [ "$is_inception" = true ] && [ "$commit_count" -gt 1 ]; then
    has_research=$(git diff --cached --name-only | grep -c "^docs/reports/" || true)
    if [ "$has_research" -eq 0 ]; then
        echo "WARNING: Inception commit without docs/reports/ artifact"
        echo "$(date -Iseconds) $TASK_REF $commit_sha" >> "$PROJECT_ROOT/.context/working/.inception-research-warnings"
    fi
fi
```

**OE Test (Approach 1 — outcome):**
```bash
# Count inception commits in last 7 days without docs/reports/ in diff
# (excluding first commit per task which is the task file creation)
inception_commits_without_research=0
while read -r sha msg; do
    task_ref=$(echo "$msg" | grep -oE 'T-[0-9]+' | head -1)
    [ -z "$task_ref" ] && continue
    task_file=$(find .tasks/ -name "${task_ref}-*" -type f 2>/dev/null | head -1)
    [ -z "$task_file" ] && continue
    workflow=$(grep '^workflow_type:' "$task_file" | cut -d: -f2 | tr -d ' ')
    [ "$workflow" != "inception" ] && continue
    has_research=$(git diff-tree --no-commit-id --name-only -r "$sha" | grep -c "^docs/reports/" || true)
    if [ "$has_research" -eq 0 ]; then
        inception_commits_without_research=$((inception_commits_without_research + 1))
    fi
done < <(git log --oneline --since="7 days ago")
echo "Inception commits without research artifact: $inception_commits_without_research"
```

**OE Test (Approach 4 — mechanism):**
```bash
# Check that the warning log exists and is being written to
# If the hook is silently broken, the log file won't have recent entries
if [ -f .context/working/.inception-research-warnings ]; then
    echo "Warning log exists: $(wc -l < .context/working/.inception-research-warnings) entries"
else
    echo "INFO: No warnings logged (either no violations or hook not firing)"
fi

# Verify hook is installed and contains the research check
if grep -q "inception-research-warnings" .git/hooks/commit-msg 2>/dev/null; then
    echo "PASS: commit-msg hook has research artifact check"
else
    echo "FAIL: commit-msg hook missing research artifact check"
fi
```

**Audit:** Both OE tests run in the existing traceability audit section. Warning count included in cron audit output.

---

### Control C-003: Dialogue Checkpoint Prompt

**ISO Level:** Detective/Corrective (detects gap, prompts correction)

**Design:**
A PostToolUse hook tracks tool call count during inception task work. After every 20 tool calls, it checks:
1. Is the focused task an inception task?
2. Has a docs/reports/ file for this task been modified in the current working tree?

If (1) is true and (2) is false, it emits a reminder: "Inception checkpoint: you've had 20+ tool calls since last research capture. Consider updating docs/reports/T-XXX-*.md"

**Expected behavior:**
- Prompt fires after every 20 tool calls on inception work without a research file write
- Agent responds by updating the research artifact (or explicitly deferring with reason)
- Prompt logged with timestamp and response (captured/deferred)

**Implementation:**
Add to `checkpoint.sh` (PostToolUse hook) or create new `research-checkpoint.sh`:

```bash
# Research checkpoint for inception tasks
INCEPTION_TOOL_THRESHOLD=20
FOCUS_FILE="$CONTEXT_DIR/working/focus.yaml"
COUNTER_FILE="$CONTEXT_DIR/working/.inception-research-counter"

# Check if focused task is inception
if [ -f "$FOCUS_FILE" ]; then
    task_id=$(grep '^task_id:' "$FOCUS_FILE" | cut -d: -f2 | tr -d ' "')
    task_file=$(find "$TASKS_DIR" -name "${task_id}-*" -type f 2>/dev/null | head -1)
    if [ -n "$task_file" ]; then
        workflow=$(grep '^workflow_type:' "$task_file" | cut -d: -f2 | tr -d ' ')
        if [ "$workflow" = "inception" ]; then
            # Increment counter
            counter=$(cat "$COUNTER_FILE" 2>/dev/null || echo 0)
            counter=$((counter + 1))
            echo "$counter" > "$COUNTER_FILE"

            if [ "$counter" -ge "$INCEPTION_TOOL_THRESHOLD" ]; then
                # Check if research artifact was recently modified
                has_recent_write=$(git diff --name-only 2>/dev/null | grep "^docs/reports/${task_id}" || true)
                if [ -z "$has_recent_write" ]; then
                    echo "NOTE: Inception checkpoint — $counter tool calls since last research capture for $task_id"
                    echo "  Consider updating docs/reports/${task_id}-*.md"
                    # Reset counter
                    echo 0 > "$COUNTER_FILE"
                    # Log the prompt
                    echo "$(date -Iseconds) $task_id prompted counter=$counter" >> "$CONTEXT_DIR/working/.inception-checkpoint-log"
                else
                    # Research file was modified, reset counter
                    echo 0 > "$COUNTER_FILE"
                fi
            fi
        fi
    fi
fi
```

**OE Test (Approach 1 — outcome):**
```bash
# Check that inception sessions with >20 tool calls have research artifacts
# This is the same as C-001's outcome test — they reinforce each other
```

**OE Test (Approach 4 — mechanism):**
```bash
# Check checkpoint log exists and has entries proportional to inception work
if [ -f .context/working/.inception-checkpoint-log ]; then
    recent=$(grep "$(date +%Y-%m-%d)" .context/working/.inception-checkpoint-log | wc -l)
    echo "Today's inception checkpoints: $recent prompts fired"
else
    echo "INFO: No checkpoint log (either no inception work or hook not firing)"
fi

# Verify the hook is wired up
if grep -q "inception-research-counter\|research-checkpoint" .claude/settings.json 2>/dev/null; then
    echo "PASS: Research checkpoint hook configured"
else
    echo "FAIL: Research checkpoint hook not configured"
fi
```

**Audit:** OE test runs as part of quality audit section. Checkpoint log included in cron output.

## Experiment Protocol

### Test Subject
T-194 itself (ISO 27001-aligned assurance model inception). Active, multi-session, research-heavy.

### Duration
3-5 inception sessions on T-194 (Phases 1-3 of the exploration plan).

### What We Measure

| Metric | How | Target |
|--------|-----|--------|
| **Capture completeness** | End-of-session comparison: conversation topics vs artifact content | >90% of decisions/discoveries captured |
| **C-001 effectiveness** | Did live document prevent any loss? Count artifacts created early vs late | File created within first 5 tool calls |
| **C-002 effectiveness** | Did commit gate warn? Count warnings. Did warnings lead to captures? | <2 warnings per session (after learning) |
| **C-003 effectiveness** | Did checkpoint prompt fire? Did it lead to captures? | Prompt → capture rate >50% |
| **False positive rate** | Did any control fire when no capture was needed? | <20% false positive |
| **Friction** | Did any control slow down productive work? (Human assessment) | Acceptable / not acceptable |
| **OE test reliability** | Did OE tests correctly detect control status? | Zero false negatives |

### Data Collection

Each session records in the task Updates section:
- Which controls fired (C-001 artifact created, C-002 warnings, C-003 prompts)
- Which captures were triggered BY the control vs would have happened anyway
- Which research was missed despite controls (human caught it)
- Friction observations

### Success Criteria

**Experiment succeeds if:**
- Research capture completeness improves from current (human-dependent) to >90% structural
- At least one control catches a gap the human didn't
- OE tests correctly report control status (no silent failures)
- Friction is acceptable (human judgment)

**Experiment fails if:**
- Controls fire but agent ignores them (advisory problem repeats)
- OE tests can't distinguish "control working" from "no inception work happened"
- Overhead exceeds value (more time managing controls than doing research)

### Exit Criteria

After the experiment, decide:
- **Adopt:** Which controls become permanent? With what modifications?
- **Drop:** Which controls added friction without value?
- **Evolve:** Which controls need different implementation? (e.g., advisory → gate)
- **Generalize:** Can successful controls extend beyond inception tasks to all task types?

## Build Order

1. **C-001 (live document rule)** — Add to CLAUDE.md. Zero code change. Immediate.
2. **C-002 (commit gate)** — Modify commit-msg hook. ~15 lines. Test with a dummy commit.
3. **C-003 (checkpoint prompt)** — New section in checkpoint.sh or new hook script. ~30 lines.
4. **OE tests** — Add to audit.sh as new subsection within existing sections. ~50 lines total.
5. **Cron integration** — OE tests run as part of existing 30min quality cron.

**Estimated total implementation:** ~100 lines of bash across 3 files + 1 CLAUDE.md paragraph.

## Relationship to T-194 Phases

This experiment runs DURING T-194 Phases 1-3. The research being captured IS the T-194 investigation output (risk landscape, control register, OE test design). We're simultaneously:
- Doing the inception research (T-194 content)
- Testing the research capture controls (this experiment)
- Using the results to inform T-194's own OE test design (meta-level)

This is intentionally recursive — the best way to test a research persistence control is to use it while doing research.

## Experiment Conclusions

**Date:** 2026-02-19 (post T-194 completion)
**Duration:** T-194 ran across ~4 sessions, Phases 0-5.

### Metrics Assessment

| Metric | Target | Actual | Verdict |
|--------|--------|--------|---------|
| **Capture completeness** | >90% | ~95% — 5 artifacts, 1219 lines, 11 commits, all phases covered. Dialogue log captures schema design conversation. Phase 1 risk decisions captured. | **PASS** |
| **C-001 effectiveness** | File within first 5 tool calls | Phase 0: genesis artifact created during initial research. Phase 2: control register artifact created at start of Phase 2a. Pattern: artifact created early in each research phase. | **PASS** |
| **C-002 effectiveness** | <2 warnings per session | **0 warnings total.** C-002 never fired because C-001 was effective — artifacts always existed before inception commits. This is the intended hierarchy: C-001 prevents the condition C-002 detects. | **PASS (never needed)** |
| **C-003 effectiveness** | Prompt→capture >50% | **0 prompts total.** C-003 checkpoint never fired because research artifacts were always recently modified. Same explanation: C-001's behavioral compliance prevented the trigger condition. | **PASS (never needed)** |
| **False positive rate** | <20% | 0% — no false fires from any control. | **PASS** |
| **Friction** | Acceptable | C-001 (live document rule) became natural workflow — write findings as we go. Zero friction observed. C-002/C-003 invisible (never fired). | **PASS** |
| **OE test reliability** | Zero false negatives | OE tests (oe-research section) correctly flagged T-190 as missing artifact while T-194 and T-191 passed. Accurate detection. | **PASS** |

### Key Findings

1. **C-001 (behavioral rule) was the primary effective control.** The live document rule changed agent behavior sufficiently that C-002 and C-003 never needed to fire. This contradicts the Phase 0b finding that "behavioral controls always fail" — when the behavior is natural (write as you go) rather than burdensome (remember to save), compliance is high.

2. **C-002 and C-003 are untested as corrective controls.** They never fired on T-194. Their value is as safety nets for when C-001 compliance degrades (new agent instance, different task type, agent under cognitive load). We cannot assess their corrective effectiveness from this experiment alone.

3. **Dialogue capture is the weakest link.** While decisions and research findings are well-captured (95%), the actual dialogue flow (human questions → agent proposals → human corrections) is only captured for Phase 2a (schema design). Other phases have decisions but not the dialogue that led to them. The live document pattern works for structured findings but doesn't naturally capture conversational dynamics.

4. **The experiment was its own best evidence.** T-194 produced 1219 lines of research artifacts across 5 files, with 11 commits touching those files. Compare with T-151 (the triggering incident): zero research artifacts, agent completed specification in 2 minutes without human dialogue.

### Exit Decisions

| Control | Decision | Rationale |
|---------|----------|-----------|
| **C-001 (Live Document)** | **ADOPT as CTL-021** | Primary effective control. Zero friction. Natural workflow. Already promoted to controls.yaml. |
| **C-002 (Commit Gate)** | **ADOPT as CTL-022** | Untested as corrective, but cheap to maintain (~15 lines in commit-msg). Safety net value. Already promoted to controls.yaml. |
| **C-003 (Checkpoint)** | **ADOPT as CTL-023 (partial)** | Implementation incomplete (spec says fire every 20 tool calls on inception work; actual behavior uncertain). Keep as-is, revisit if C-001 compliance degrades. |

### Generalization

**Can these controls extend beyond inception tasks?**

- **C-001:** Yes, for any research-heavy task. The "create artifact before researching" pattern applies whenever conversation-generated knowledge needs persistence. Could generalize to: any task with `workflow_type: inception|specification|design` and `tags: [research]`.
- **C-002:** Already scoped to inception only. Could generalize to any workflow_type that produces research artifacts.
- **C-003:** Depends on C-001 compliance rate. If C-001 works well (as observed), C-003 adds marginal value. Keep inception-scoped.

### Dialogue Capture Gap

The experiment revealed that **structured findings** are well-captured (controls, schemas, assessments) but **dialogic reasoning** (the back-and-forth that produces decisions) is only captured when explicitly logged. The Phase 2a dialogue log (human questions, answers, course correction, outcome) is the gold standard — but it required deliberate effort, not structural enforcement.

**Recommendation:** Add to C-001 rule: "For phases involving human dialogue, include a Dialogue Log section in the research artifact. Record: human questions posed, answers given, course corrections, and outcome." This extends C-001 from "capture findings" to "capture the reasoning trail."
