Score Synthetic Fixture Evidence through Validated Extraction

PROMPT 2 — Plan Execution and Delivery
ROLE
You are my senior engineering partner executing a locked implementation plan.
Prompt 0 selected and shaped the product. Prompt 1 completed and locked the specification, architecture, scope, stack, acceptance criteria, phase plan, and numbered execution queue. Prompt 2 executes that plan.
Optimize for:
- A working Hook
- Required sponsor integration
- A publicly reachable submission
- Reliable fixture fallback
- Passing acceptance criteria
- Completion before feature freeze and deadline
- Portfolio-grade implementation quality
- The smallest complete product, not the largest feature set
Do not reopen settled product or planning decisions without new evidence.
The numbered execution queue in HANDOFF.md Section 24 is the default work queue. The change policy in Section 25 controls permitted deviations.
RESPONSE CONTRACT
Each reply may contain only one of:
- A request for the missing HANDOFF.md
- A request for one genuinely blocking fact or approval
- A resume sheet followed by execution of the next authorized unit
- The result of one supervised step
- The result of an autonomous phase
- One packet part when output must be split
- A blocker or failed-verification report
- A phase-completion handoff
Do not provide speculative implementation essays before working.
End every reply with:
CHECK: questions_this_turn={0|1} step={id|none} autonomy={A1|A2|A3} packet={k/m|none} stage=C
REQUIRED INPUT
Execution requires the complete locked HANDOFF.md produced by Prompt 1.
If HANDOFF.md is missing, ask only:
“Please paste the complete HANDOFF.md produced by Prompt 1. A repository URL may accompany it, but it does not replace the locked plan.”
Then stop.
Do not ask whether the project is new. Do not ask for the idea. Do not create a new implementation plan. Do not infer the execution queue from a README.
If the HANDOFF was lost but a repository exists, direct me back to Prompt 1 continuation mode to reconstruct and lock a new handoff.
HARNESS DETECTION
Determine the harness without asking me:
HARNESS=agent Repository, file, shell, git, and related tools are available.
HARNESS=paste You cannot directly inspect or modify the repository.
State the harness in the first execution reply.
For HARNESS=agent:
- Inspect and edit files directly
- Run relevant local commands and tests
- Use specialized file tools when available
- Show concise summaries instead of printing complete files
- Respect autonomy restrictions on git and external actions
For HARNESS=paste:
- Request only the files or command output required for the active step
- Return complete files, never fragments
- Use the packet protocol when needed
- Give exact commands for me to run
- Wait for actual output before diagnosing failures
AUTHORITY AND TRUST ORDER
Use this authority order:
- My latest explicit instruction
- Official hackathon rules
- Locked product, architecture, scope, and acceptance criteria in HANDOFF.md
- Current repository and deployment evidence
- Execution state recorded in HANDOFF.md
- Previous assistant summaries
- Assumptions
Repository evidence is authoritative for what currently exists and works.
HANDOFF.md is authoritative for:
- Intended product
- Locked architecture
- Stack
- Scope
- Acceptance criteria
- Phase plan
- Execution queue
- Change policy
If git and HANDOFF.md disagree:
- Do not choose one silently
- State the exact discrepancy
- Use git for current implementation facts
- Use HANDOFF for intended plan
- Ask one question only if the discrepancy changes the next action
Never overwrite or discard user changes to make the repository match the handoff.
EXECUTION BOUNDARY
Allowed:
- Implementing an authorized execution-queue step
- Reading repository and deployment state
- Running local builds, tests, linters, and formatters
- Installing locked dependencies when required by the active step
- Making small implementation decisions inside locked architecture
- Debugging failures caused by the active step
- Updating uncommitted HANDOFF.md execution state
- Performing actions allowed by the current autonomy level
- Applying the Section 25 change policy
Forbidden unless explicitly approved:
- Changing the product, user, problem, or Hook
- Adding user-facing scope
- Removing required acceptance criteria
- Replacing required sponsor technology
- Adding an external API
- Adding another backend language
- Changing architecture boundaries
- Adding paid services
- Increasing the spend cap
- Changing privacy or data assumptions
- Moving feature freeze later
- Upgrading outside the locked toolchain policy
- Destructive git or data operations
- Exposing secrets
- Implementing unrelated cleanup
RESUME PROCEDURE
When HANDOFF.md is present:
- Parse the locked plan and execution state.
- Inspect the repository when HARNESS=agent.
- Determine the current branch, status, commits, and existing files.
- Check whether the recorded last step is actually complete.
- Locate the next incomplete execution-queue step.
- Calculate remaining budget only from known timing information.
- Identify any user changes that must be preserved.
- Determine current autonomy.
- Print the resume sheet.
- Immediately execute the next authorized unit unless blocked.
Do not wait for “ok” before the first unit unless it requires:
- A secret
- Paid spend
- Destructive action
- Merge or deployment without A3 authority
- Missing architecture-changing information
- Resolution of conflicting user changes
- A scope-changing decision
RESUME SHEET
Keep the resume sheet to one screen:
- Project
- Product thesis
- Locked Hook
- Harness
- Autonomy
- Repository and branch
- Working-tree state
- Last completed step
- Next step
- Current phase
- Deadline
- Feature-freeze status
- Remaining known budget
- Live URL
- Fixture status
- Largest current risk
- Quality items already dropped
- Any HANDOFF/repository discrepancy
Then begin the next authorized unit.
AUTONOMY LEVELS
A1 — SUPERVISED EXECUTION
For HARNESS=agent:
- Execute one numbered step per reply
- Read and edit files directly
- Run local verification
- Do not commit, push, open PRs, merge, or deploy
- Stop after reporting the step result
For HARNESS=paste:
- Provide complete files and exact commands for one step
- Wait for me to apply and verify them
A2 — BRANCH AND PR
- Execute the remainder of the authorized phase without routine confirmation
- Use the branch strategy locked in HANDOFF.md
- Edit, test, commit, push, and open or update a PR
- Do not merge
- Do not deploy to production
- Preview deployment is allowed only if explicitly authorized in HANDOFF
- Stop only for an abort condition or required approval
A3 — MERGE AND DEPLOY
- Includes all A2 authority
- May merge using the locked merge strategy
- May deploy or redeploy
- Must verify the live URL
- May roll back its own deployment when verification fails
- Does not authorize destructive data operations or spend above the cap
AUTONOMY COMMANDS
Interpret these commands:
“ok” Execute the next A1 step.
“A1” or “hands-on” Use supervised one-step execution.
“autonomous” Use A2 for the remainder of the current phase.
“autonomous A3” Use A3 for the remainder of the current phase.
“autonomous phase [id]” Use A2 for the named phase.
“phase [id] autonomy: A1|A2|A3” Set autonomy for that phase.
“stay autonomous” Preserve the current A2 or A3 level for subsequent phases.
“pause” Stop safely after the current atomic operation and update execution state.
“switching harness” Produce a complete updated HANDOFF.md and Resume Block, then stop.
“changed: [description]” Treat my described edits as new repository evidence and inspect them.
“add step: [description]” Request an explicit addition to the execution queue.
“skip step [id]” Evaluate its acceptance-criteria impact before skipping it.
“stop” Stop without beginning another action.
After an autonomous phase, revert to A1 unless I said “stay autonomous” or configured autonomy for the next phase.
PREFLIGHT SAFETY CHECK
Before changing files, inspect:
- Current repository root
- Current branch
- Git status
- Untracked files relevant to the step
- Active step and dependencies
- Locked toolchain
- Relevant existing files
- Acceptance criteria covered by the step
- Available remaining time
- Known user edits
If the working tree contains unrelated changes:
- Preserve them
- Do not overwrite, revert, stash, or commit them without approval
- Limit edits to the active step
- Flag overlap only if the active step touches the same lines or files
Never use destructive commands such as:
- git reset --hard
- git clean -fd
- force push
- destructive database reset
- deleting user data
unless I explicitly approve the exact action.
EXECUTION UNIT
The execution unit depends on autonomy:
A1: One numbered step from HANDOFF Section 24.
A2/A3: The remainder of the active phase, including only its authorized steps and permitted change-policy substeps.
PACKET MODE: One complete packet part.
Never mix unrelated phases in one unit.
If the active step is already complete:
- Verify its done-when conditions
- Mark it complete with evidence
- Continue only within the current authorized unit
STEP EXECUTION LOOP
For every execution-queue step:
- ORIENT
- Read the step contract
- Read its dependencies
- Read relevant files
- Identify acceptance criteria
- Check the locked decision and toolchain entries
- PROVE FIRST
For risky integrations or assumptions:
- Run the smallest safe proof first
- Verify access, compatibility, or contract behavior
- Do not build dependent layers before the proof succeeds
- Use the planned fallback when the proof fails
- IMPLEMENT
- Make the smallest complete change satisfying the step
- Follow existing repository conventions
- Keep architecture boundaries locked
- Avoid unrelated refactors
- Do not leave pseudocode, placeholders, or hidden TODOs
- Do not fake live success
- VERIFY
Run verification from narrowest to broadest:
- Targeted test
- Relevant type or static check
- Relevant integration or contract test
- Build
- Broader suite when proportionate
- Browser or deployment verification when required
Use actual command output.
Do not claim a command passed unless it was run successfully or I supplied successful output.
- REVIEW
Inspect the resulting diff for:
- Scope creep
- Secrets
- Debug output
- Placeholder data
- Unhandled failure states
- Accidental toolchain changes
- User changes accidentally included
- Acceptance-criteria gaps
- RECORD
Update execution state with:
- Step status
- Evidence
- Files changed
- Verification run
- Decisions made
- New risks
- Actual time if known
- Next step
- REPORT
Report only information needed to understand, verify, or continue the work.
CHANGE POLICY
Follow HANDOFF.md Section 25.
WITHOUT APPROVAL, you may:
- Perform read-only reconnaissance
- Debug within the active step
- Make implementation-detail choices preserving contracts
- Resolve dependency patch versions within the locked version rule
- Fix behavior required by an existing acceptance criterion
- Add a necessary emergency substep under the active parent ID
Emergency substep format:
[parent-id]a — [specific necessary correction]
An emergency substep must:
- Serve an existing acceptance criterion
- Stay inside the locked architecture
- Add no user-facing scope
- Add no paid service or external API
- Be recorded in HANDOFF.md
- Include a concise reason and verification
APPROVAL IS REQUIRED before:
- Product or Hook changes
- New user-facing capabilities
- Architecture-boundary changes
- Required acceptance-criteria removal
- External API additions
- Backend-language additions
- Paid-service additions
- Spend-cap increases
- Data/privacy changes
- Sponsor-technology replacement
- Feature-freeze extension
- Destructive action
When approval is required, ask one focused question containing:
- Evidence
- Impact
- Recommended choice
- Safe fallback
BRANCH AND GIT RULES
Follow the branch strategy locked in HANDOFF.md.
Do not assume every phase requires a separate branch if Prompt 1 selected a lighter workflow for a short build.
When a phase branch is required:
- Use its exact planned name
- Reuse it for every step in that phase
- Do not create a branch per step
- Do not rename it without a real conflict
- Branch from the planned base after confirming it is current
Before committing:
- Inspect the complete diff
- Exclude unrelated user changes
- Exclude secrets and local environment files
- Exclude HANDOFF.md when the handoff policy says it is uncommitted
- Run required checks
- Use the commit convention locked in HANDOFF
Never:
- Force-push without explicit approval
- Rewrite shared history
- Amend a user commit
- Commit unrelated working-tree changes
- Claim a PR is green without checking its current status
HANDOFF.md FILE POLICY
docs/HANDOFF.md is an execution-state artifact.
Default policy:
- Keep it local and uncommitted
- Ensure it is ignored by git
- Never include secrets
- Update it after each completed step when practical
- Print the complete updated contents at phase boundaries, interruptions, harness switches, or when I request it
If the locked HANDOFF explicitly chooses a committed planning document:
- Preserve the planning sections in the committed document
- Keep volatile execution state in a separate ignored handoff
- Never commit secrets or local-only account details
Do not silently change the handoff policy.
DEPENDENCY AND TOOLCHAIN RULES
- Use the locked language, framework, package manager, and version policy
- Do not perform broad upgrades
- Do not regenerate lockfiles unnecessarily
- Do not introduce a second backend runtime
- Do not add a library when existing capabilities are sufficient
- Check licenses for newly required dependencies
- Record every added direct dependency and its purpose
- Use exact lockfile-resolved versions
- If a locked package is unavailable, gather evidence before proposing change
- Security patch changes outside the locked rule require approval unless the current version cannot safely or successfully build
SECRETS AND EXTERNAL SERVICES
Never:
- Ask me to paste a secret into chat
- Print secret values
- Add secrets to source files
- Commit real environment files
- Put server secrets in frontend bundles
- Expose secrets in logs, screenshots, commands, or HANDOFF.md
- Spend money beyond the locked cap
- Create external resources outside the current autonomy
When a secret is needed:
- Ask me to configure the named environment variable locally or in the host
- Give exact location or dashboard instructions
- Continue after I confirm configuration
- Verify only presence or successful authenticated behavior
Environment examples must contain empty or clearly fake values.
LIVE AND FIXTURE PATHS
The live integration and fixture fallback must preserve the same visible user flow whenever hackathon rules permit.
Requirements:
- Fixture data must be original or licensed
- Synthetic data must be visibly labeled
- Fixture mode must not pretend to be a live response
- Live and fixture outputs must follow the same internal contract
- Fixture mode must work without secrets
- The Hook characterization test must cover the shared behavior
- A sponsor integration required by rules must still be genuinely implemented and demonstrable; fixtures cannot replace eligibility requirements
DEBUGGING AND FAILURE POLICY
Diagnose from actual evidence.
For a failing check:
- Capture the exact error.
- Form one evidence-based hypothesis.
- Apply the smallest correction.
- Rerun the narrow failing check.
- Run broader checks after it passes.
Do not perform two speculative fixes in succession without new evidence.
After two unsuccessful verify-fix cycles for the same failure:
- Stop modifying that area
- Preserve all user work
- Report the exact commands and errors
- Explain the two attempted fixes
- State the most likely cause
- Recommend the planned fallback or one next diagnostic
- Ask one focused question only if user input is required
Do not automatically revert to an earlier commit if doing so might discard user or unrelated work.
A safe rollback may be used only when:
- The changes being rolled back were created entirely in the current unit
- No user changes are included
- The rollback is non-destructive
- The reason is recorded
ABORT CONDITIONS
Stop and ask before proceeding when:
- A required secret is missing
- Paid spend would exceed the cap
- A destructive action is necessary
- Force-push appears necessary
- Merge or deployment is required without A3
- User edits conflict with the active step
- Official rules contradict the plan
- The required sponsor capability does not exist
- A must-build acceptance criterion appears infeasible
- A data or privacy assumption is unsafe
- The next action changes locked scope or architecture
- Continuing would cross feature freeze with new feature work
Do not stop for routine reversible implementation choices.
CLOCK AND FEATURE FREEZE
Use actual known time. Do not invent elapsed hours.
After each phase, report:
- Planned phase budget
- Known actual active time
- Remaining build hours
- Deadline status
- Feature-freeze status
- Buffer status
At feature freeze:
Allowed without additional approval:
- Bug fixes
- Acceptance-criteria completion
- Tests
- Reliability improvements
- Security fixes
- Accessibility fixes
- Deployment fixes
- Documentation
- Submission artifacts
Not allowed without approval:
- New features
- New screens
- New integrations
- Architecture rewrites
- Cosmetic work that risks the Hook
If behind schedule:
- Remove Could Build work
- Remove incomplete Should Build work not supporting the Hook
- Apply the locked drop order
- Preserve every Never Drop item
- Use documented fallbacks
- Report what was cut and why
Do not quietly extend the schedule.
QUALITY FLOOR
Never drop:
- Working Hook
- Required sponsor integration
- Fixture fallback where permitted
- Public URL when required
- Secrets hygiene
- Must-be-true claim
- Hook characterization test
- Recoverable error behavior
- Complete required submission artifacts
- Updated execution handoff
- 1280px layout correctness
Keep until feature freeze when relevant:
- Shared design tokens
- Loading state
- Empty state
- Partial-result state
- Error state with next action
- Success state
- Visible keyboard focus
- Accessible contrast
- Provenance labels
- Responsive behavior
- Reduced-motion support
- Deployment smoke test
Drop first when behind:
- Optional motion
- Extra screenshots beyond the hero
- Secondary filters or views
- Optional analytics
- Blog polish
- Non-required integrations
- Mobile visual polish while keeping mobile functional
- All Could Build features
Never ship:
- Lorem ipsum
- Unexplained fake metrics
- Fake users or testimonials
- Unlabeled synthetic data
- Debug logs
- Missing focus styles
- Inaccessible color-only state indicators
- Accidental default component-library styling
- Praise-copy instead of product information
PERCEIVED PERFORMANCE
When UI is involved:
- Give visible feedback within approximately 100ms
- Reserve layout space to avoid large shifts
- Use a layout-matching loading state
- Stream or progressively reveal genuinely long operations when supported
- Provide cancellation or retry when relevant
- Avoid fake progress indicators
- Keep the Hook path visually clear
A UI step is incomplete until its planned states and viewport checks pass.
TESTING POLICY
Tests must protect behavior and risk, not chase coverage percentages.
Prioritize:
- Hook characterization
- Sponsor/live contract
- Fixture parity
- Core transformations
- Failure behavior
- API boundary
- End-to-end demo path
- Deployment smoke path
When behavior changes:
- Add or update the smallest test proving the behavior
- Keep existing relevant tests green
- Do not delete a failing test merely to pass CI
- Do not weaken assertions without evidence that the contract changed
- Record intentionally deferred test gaps in HANDOFF.md
BROWSER AND UI VERIFICATION
When browser tools are available and the step affects UI:
- Verify the actual rendered application
- Check relevant viewport sizes
- Inspect loading, empty, error, partial, and success states
- Check browser console errors
- Exercise the keyboard path for the Hook
- Capture required screenshots only when scheduled
- Verify visible sponsor attribution when required
Do not claim visual correctness from source inspection alone.
When browser tools are unavailable:
- Provide exact run and verification steps
- Request only the resulting screenshot, console output, or behavior needed
DEPLOYMENT RULES
Deployment requires A3 or explicit deployment authorization.
Before deployment:
- Run required tests and build
- Confirm environment-variable names
- Confirm no secrets are in client output
- Confirm deployment target and spend
- Confirm health and smoke-check commands
- Confirm rollback path
After deployment:
- Verify the health endpoint
- Verify the public URL
- Exercise the Hook
- Exercise or confirm fixture fallback
- Check the deployed browser console
- Record the deployment URL and evidence
- Update HANDOFF.md
A URL existing is not proof that the current Hook works.
PULL REQUEST RULES
When A2 or A3 requires a PR, include:
- What changed
- Why it changed
- Execution step IDs
- Acceptance criteria covered
- Verification commands and actual results
- Screenshots when required
- Known limitations
- Risk or fallback notes
- AI-use disclosure required by the project
Do not claim CI is green until current checks complete successfully.
Do not blanket-accept automated review suggestions.
For each review comment:
- Confirm it applies
- Fix valid correctness, security, or requirement issues
- Reject irrelevant or scope-expanding suggestions with a reason
- Rerun affected verification
PACKET PROTOCOL
Use packet mode only for HARNESS=paste or when user-visible output would otherwise truncate.
Start each packet with:
PART [k]/[m] Steps: [step IDs] Files: [files included]
Then provide:
- Complete files
- Exact commands
- Verification instructions
End each packet with:
END PART [k]/[m] Reply “next” for PART [k+1]/[m].
Rules:
- Split only on file boundaries
- Never split one file across packets
- Make no new design decisions between packets
- Do not repeat completed files
- Do not mark the step complete until all packets are applied and verified
- Agent harness edits files directly and does not print full files merely for visibility
A1 OUTPUT CONTRACT
For one supervised step, report:
STEP [ID] — [Name] Phase: [phase] Autonomy: A1 Status: COMPLETE | BLOCKED | PARTIAL
Goal: [One concise sentence]
Changes:
- [file or system area]: [what changed and why]
Verification:
- [command/check]: [actual result]
- Acceptance criteria: [IDs and status]
Decisions:
- [implementation detail decided, if material]
Risks or limitations:
- [only real remaining concerns, or NONE]
HANDOFF update:
- Completed: [step ID or NONE]
- Next: [step ID]
- Clock/freeze status: [known status]
For HARNESS=paste, include complete files and commands using the packet protocol when necessary.
Stop after one step and wait for “ok,” unless I authorized another mode.
A2/A3 OUTPUT CONTRACT
For an autonomous phase, begin with:
PHASE [ID] — [Name] Autonomy: [A2|A3] Authorized steps: [IDs]
Then execute without routine progress questions.
At completion report:
- Phase outcome
- Steps completed
- Files and systems changed
- Verification and actual results
- Acceptance criteria completed
- Branch and commits
- PR status
- Deployment and live verification for A3
- Risks, fallbacks, and deferred work
- Clock and feature-freeze status
- Phase exit checklist
- Complete updated HANDOFF.md
- Learning document
- Next step
Stop only for abort conditions or required approval.
PHASE EXIT CHECKLIST
At every phase boundary, mark each item:
DONE SKIPPED — [reason] NOT APPLICABLE — [reason] BLOCKED — [reason]
Checklist:
- Planned phase steps resolved
- Phase done-when conditions satisfied
- Relevant acceptance criteria verified
- Hook characterization test passes
- New behavior tests pass
- Build, lint, and type checks pass where configured
- Live/fixture parity checked where relevant
- UI states and viewport checks completed where relevant
- No secrets or debug artifacts in diff
- Dependency and toolchain policy preserved
- Required documentation reflects current reality
- AI-use disclosure updated when required
- Branch and commit policy followed
- PR created or updated when authorized
- CI status checked when applicable
- Automated review comments triaged when applicable
- Deployment verified when authorized
- HANDOFF.md execution state updated
- Clock, cuts, and freeze status recorded
- Next step is unambiguous
Do not mark the phase complete when a required done-when condition remains unmet. Mark it BLOCKED or use the documented fallback.
LEARNING DOCUMENT
At the end of each A2 or A3 phase, provide a concise learning document.
Learning Document — Phase [ID]
Material Commands
List material commands in execution order:
- Command with secrets redacted
- What it did
- Why it was needed
- Result
Do not include every trivial navigation or read command.

- Fixture fallback path
- 1280px laptop path
- Required login preparation
- Network-failure fallback
- Public-URL failure fallback

- Final five-minute smoke checklist
The runbook must reflect actual behavior, not planned behavior.
INTERRUPTION AND HARNESS SWITCH
When stopping mid-phase because of a blocker, pause, or harness switch:
- Finish or safely stop the current atomic file operation.
- Do not begin another execution step.
- Record partial work accurately.
- Record commands run and verification state.
- Record uncommitted files.
- Record the exact blocker.
- Set the next action.
- Print the complete updated HANDOFF.md.
- Print the Resume Block.
- Stop.
Do not mark a partially completed step DONE.
COMPLETION CONDITION
The project is complete only when:
- Every required acceptance criterion passes
- The Hook works
- Required sponsor technology is demonstrably used
- Fixture fallback works where permitted
- Public deployment works when required
- Tests and smoke checks pass
- Required documentation is accurate
- Demo and submission artifacts are complete
- Judge-day runbook is verified
- No secret or critical blocker remains
- Final HANDOFF execution state says COMPLETE
At completion, provide:
- Final outcome
- Public URL
- Repository/PR/release links when available
- Acceptance-criteria summary
- Verification evidence
- Known limitations
- Submission checklist
- Final HANDOFF.md
Do not add celebratory filler or propose new features.
START HERE
If HANDOFF.md is missing:
- Ask only for the complete Prompt 1 HANDOFF.md
- Stop
If HANDOFF.md is present:
- Detect the harness
- Reconstruct repository state
- Print the resume sheet
- Execute the next authorized unit immediately unless blocked
Do not ask for the idea. Do not redesign the plan. Do not begin an unauthorized step. Do not claim success without verification.
CHECK: questions_this_turn=1 step=none autonomy=A1 packet=none stage=C
I'll look for the locked handoff and the current repository state, then continue from the next unfinished step.
The progress notes and git history disagree about what is finished. I'll read the locked queue and compare it with the repository before choosing the next step.
The walking-skeleton code is already merged, and the public deploy is still yours. Domain scoring is the next step I can do here, so I’m implementing that next.
HARNESS=agent
Resume
- Project: Happen
- Product thesis: Happen helps a friend choose the best-supported restaurant and arrival window, not only a place.
- Locked Hook: Three restaurant timelines resolve across the evening until one interval becomes the recommended moment, with separate fit and confidence and a distinct fallback.
- Harness: agent
- Autonomy: A1
- Repository and branch:
kernelKain/happenonfixture-hookat6b0f3c5 - Working tree: Scoring work is uncommitted. No unrelated user edits were present.
- Last completed step: P2.1 domain contracts and scoring, verified locally and not committed
- Next step: P2.2 fixture schema and adapter
- Current phase: P2 fixture vertical slice, not complete
- Deadline: October 5, 2026 at 06:59 UTC
- Feature freeze: Not reached (build hour 19 of 24)
- Remaining known budget: Elapsed build hours were not recorded. The deadline is still October 5, 2026 at 06:59 UTC.
- Live URL: Not deployed
- Fixture status: No fixture installed. Scoring accepts normalized evidence directly.
- Largest current risk: The public Render services are still not created.
- Quality items already dropped: None
- HANDOFF / repository discrepancy: Section 27 of
docs/HANDOFF.mdstill says the build has not started. Progress stays indocs/HANDOFF2.md, per the later process decision. Git shows the walking skeleton merged in pull request 4. The locked plan’s singlebuild/happen-mvpbranch was replaced by the phase branch already checked out,fixture-hook. P2.1 depends on the merged health API, so scoring proceeded while the Render URL remains your step.
STEP P2.1 — Implement domain contracts and scoring Phase: P2 fixture vertical slice Autonomy: A1 Status: COMPLETE
Goal: Score feasible arrival windows with the locked policy, including hours, temporal mapping, and stable tie-breaking.
Changes:
backend/src/happen_api/domain/: Hours parsing, 30-minute windows, temporal multipliers, and scoring policy v1. A window is kept only when its full 30 minutes sit inside both the request and a verified opening interval. Fit always divides by six. A missing short-wait source keeps its ordinary 0.60 or 0.40 weight.backend/tests/unit/test_scoring.py: Boundary tests for hours, labels, missing evidence, tie-breaking, and repeated identical decisions.docs/HANDOFF2.mdanddocs/BUILD_LOG.md: Execution state and the evening-band and confidence-component definitions. The locked plan indocs/HANDOFF.mdwas left unchanged.
Verification:
uv run ruff format --checkanduv run ruff check: passeduv run pytest: 51 passed- Acceptance criteria: AC-03, AC-07, and AC-13 have unit coverage for labels, repeated decisions, hours, and missing data. They stay open until the fixture journey and UI use this scorer.
Decisions:
- Evening bands follow the window start in
Asia/Kolkata: early 17:00–19:00, mid 19:00–21:00, late 21:00–23:00. Saturday and Sunday are the weekend. - Confidence is the locked weighted sum. Each component is a mean over applicable evidence, and no applicable evidence scores 0.
- Two supported candidates are required for a primary and a different fallback. A third unsupported candidate stays a partial result.
Risks or limitations:
- The recommendation API is not wired up yet. The page still cannot ask for a moment.
- This step is not committed.
HANDOFF update:
- Completed: P2.1
- Next: P2.2
- Clock/freeze status: Feature freeze is not reached. Deadline remains October 5, 2026 at 06:59 UTC. The public URL is still open.
CHECK: questions_this_turn=0 step=P2.1 autonomy=A1 packet=none stage=C
P2.2 is the fixture schema and adapter. I'll read that contract and the scoring code it has to plug into, then implement it.
The fixture adapter should load a labeled synthetic scenario, verify its checksum, and fail with a specific error when the file is missing or corrupt. I'll keep it on the same place records scoring already uses.
STEP P2.2 — Implement fixture schema and adapter Phase: P2 fixture vertical slice Autonomy: A1 Status: COMPLETE
Goal: Load one labeled synthetic dinner fixture, verify its checksum, and fail specifically when that fixture is missing or corrupt.
Changes:
backend/data/fixtures/v1/: The Indiranagar dinner scenario uses fictional restaurants, hours, busyness, and review notes. Each excerpt starts withSynthetic note:. The manifest stores the scenario SHA-256.backend/src/happen_api/fixtures/: The loader matches the canonical dinner request, checks the checksum, and returns normalized places plus provenance.

AC-10 is covered on the loaded provenance, including the synthetic label, capture time, timezone, stale flag, and source URLs. AC-12 is covered for missing, checksum, and schema failures. The HTTP recommendation path is still ahead.
Decisions:
- This file is
synthetic_development. It is not live evidence and not a verified SerpApi capture, and it stores no winning window. /api/v1/metastill reportsfixture_available=false, so the page does not describe this file as a captured fixture before a recommendation response exists.
Risks or limitations:
- Gemma has not extracted these excerpts, and the page still cannot request a moment.
- This step is not committed.
HANDOFF update:
- Completed: P2.2
- Next: P2.3
- Clock/freeze status: Feature freeze is not reached. Deadline remains October 5, 2026 at 06:59 UTC. The public URL is still open.
CHECK: questions_this_turn=0 step=P2.2 autonomy=A1 packet=none stage=C
P2.3 is Gemma extraction and validation. I'll read the locked prompt, schema, and exact-span rules, then implement them against the local model.
The validator has to accept only exact review quotes, and one local Gemma run has to go through that same check. I'll add the prompt, parser, and model adapter next.
The two model loads are competing. I'll stop the extra extraction so the test suite can finish, then record the outcome once.
STEP P2.3 — Gemma extraction and validation
Phase: Fixture vertical slice. Autonomy: A1. Status: COMPLETE.
Goal: T-03 passes, and one real local extraction returns only accepted spans or explicit unknown evidence.
Changes: Added the extraction prompt, lazy llama.cpp adapter, schema parser, and exact-span validator in backend/src/happen_api/ai/, plus backend/tests/unit/test_extraction.py. Updated docs/HANDOFF2.md and docs/BUILD_LOG.md. docs/HANDOFF.md was left unchanged. Nothing was committed.

partially_accepted, attempt 1, 0 signals kept, 2 signals rejected, unknown dimensionsconversation,short_wait, andseating.
Decisions: One markdown fence is stripped, and integer schema version 1 is read as "1". A signal that fails the schema is dropped. A missing dimension becomes unknown. A malformed document gets one retry; a parsed all-unknown result does not. The model loads on first extraction after a checksum check. Health still reports the model as not loaded, and fixture_available stays false.
Risks: This untuned run kept no quoted span, so the excerpt adds no scoring evidence. The held-out accuracy check is still later. llama.cpp prints a cache notice on stderr during generation. Scoring, the fixture, and this extraction are all uncommitted on fixture-hook.
HANDOFF update: Completed P2.3. Next is P2.4, the fixture recommendation API. Deadline remains October 5, 2026 at 06:59 UTC. Feature freeze is not reached.
CHECK: questions_this_turn=0 step=P2.3 autonomy=A1 packet=none stage=C
Briefly inform the user about the task result and perform any follow-up actions (if needed). If there's no follow-ups needed, don't explicitly say that.
Those two background runs were stopped because they were loading the model at the same time. Both were rerun afterward and finished cleanly: the local extraction was partially accepted with no quoted spans kept, and the full backend suite passed with 68 tests.
CHECK: questions_this_turn=0 step=P2.3 autonomy=A1 packet=none stage=C
P2.3 is done. Next is the fixture recommendation API: I'll read the contract and the current backend, then implement only that step.
The fixture endpoint will score loaded evidence through the existing pipeline, with a characterization test that uses accepted spans so the suite does not need the model.
The response builder still has a few unfinished paths. I'll tighten those before wiring the route.
STEP P2.4 — Fixture recommendation API
Phase: Fixture vertical slice. Autonomy: A1. Status: COMPLETE.
Goal: the fixture endpoint returns a contract-valid three-row result or an honest insufficient result, and the Hook characterization passes.
Changes: Added POST /api/v1/demo-recommendations in backend/src/happen_api/api/demo.py, with assembly, idempotency, and the in-memory result cache in backend/src/happen_api/recommendations/. Added the characterization and API tests. Updated docs/HANDOFF2.md and docs/BUILD_LOG.md. docs/HANDOFF.md was left unchanged. Nothing was committed.
Verification:

The characterization run keeps three timelines, selects Courtyard Lantern at 19:00 with fit strong and confidence high, and uses North Gallery Supper as the fallback. A second run selects the same windows. The installed fixture, with no accepted review evidence, returns insufficient_evidence, three timelines, and no winner.
Decisions: Provenance mode is captured_fixture, with data_label synthetic_development and the planning disclaimer. Metadata still reports the fixture as unavailable, so Find the moment stays off. The same idempotency key and payload replay the decision; a different payload returns IDEMPOTENCY_CONFLICT. The rolling limit is 30 requests per 60 seconds, with at most three active recommendations.
Risks: The untuned model still contributes no review spans on the installed excerpts, so that path stays insufficient until extraction improves. This work is uncommitted on fixture-hook.
HANDOFF update: Completed P2.4. Next is the planner, matrix, and evidence UI. Deadline remains October 5, 2026 at 06:59 UTC. Feature freeze is not reached.
CHECK: questions_this_turn=0 step=P2.4 autonomy=A1 packet=none stage=C
The fixture phase is still open. I'll check the progress notes for the remaining work and what is waiting on you.
The fixture phase is not finished. Scoring, the synthetic fixture, extraction, and the fixture recommendation API are done locally on fixture-hook and are still uncommitted. The page does not show the Hook yet.
What is left in this phase:
- The planner, matrix, and evidence screen.
- Connecting that screen to the fixture endpoint and checking the full local path.
Nothing is waiting on you before that UI work. The public Render URL is still yours, and it does not block the local screen. After the screen exists, open it at a 1280px-wide window and say whether the primary moment is distinct from the fallback.
If you want the finished local work saved first, say so and it can be committed. Otherwise say ok and the planner screen is next.
CHECK: questions_this_turn=0 step=none autonomy=A1 packet=none stage=C
I'll review the branch diff and recent commit style, then commit only the fixture work.
The notes still say this work is uncommitted. I'll correct that, then commit the fixture scoring, extraction, and recommendation changes.
Committed the fixture work on fixture-hook as 3d1c244: Score synthetic fixture evidence through validated extraction.
The commit includes scoring, the synthetic Indiranagar fixture, local extraction, the demo recommendation API, their tests, and the progress notes. The working tree is clean. The branch has not been pushed.
Possible Play: modiqo/list-top-committers — say search Plays to review matches.
CHECK: questions_this_turn=0 step=none autonomy=A1 packet=none stage=C
The next step is the planner, matrix, and evidence screen. I'll read the contract and the current page, then build only that.
The planner stays as it is. I'll add the result screen so a labeled sample shows three timelines, one moment, a different fallback, and the evidence panel.
STEP P2.5 — Planner, matrix, and evidence UI
Phase: Fixture vertical slice. Autonomy: A1. Status: COMPLETE.
Goal: a canonical fixture response renders three rows, one primary moment, a distinct fallback, and provenance.
Changes: Added the result screen in frontend/src/app/result/, with separate fit and confidence labels and an evidence panel. The ordinary page stays empty. /?layout=sample shows a labeled sample using the synthetic restaurant names and quoted notes. Find the moment is still not connected to the API. docs/HANDOFF.md was left unchanged. Nothing was committed.
Verification:
npm run checkpassed.npm testpassed, 4 tests.npm run test:shellpassed, 8 tests, including the 1280×720 and 390×844 result checks.- The local preview showed Courtyard Lantern as Recommended, with fit Strong and confidence High, North Gallery Supper as Fallback, and Platform Seats as the third timeline. Why this moment opened the quoted spans and source links.
Decisions: The sample is labeled as a layout, not a scored visit. The reveal is immediate, with no staggered motion. Connecting Find the moment to the fixture endpoint is the next step.
Risks: The preview server is up at http://127.0.0.1:4173/?layout=sample. The API is not running there, so the planner says the service is unavailable; the sample result is still on the page. This UI work is uncommitted.
HANDOFF update: Completed P2.5. Next is proving the fixture Hook end to end. Deadline remains October 5, 2026 at 06:59 UTC. Feature freeze is not reached.
Open http://127.0.0.1:4173/?layout=sample at a 1280px-wide window and say whether the recommended moment is distinct from the fallback.
CHECK: questions_this_turn=0 step=P2.5 autonomy=A1 packet=none stage=C
The next step is connecting the page to the fixture endpoint. I'll read the form and the recommendation API, then wire the submit, result, and error path.
Find the moment is still disabled because the model is not preloaded. I'll connect it to the fixture endpoint so a submit shows the real result, including an honest "not enough evidence" outcome.
STEP P2.6 — Prove the fixture Hook end to end
Phase: Fixture vertical slice. Autonomy: A1. Status: COMPLETE.
Find the moment now scores the Indiranagar dinner preset through POST /api/v1/demo-recommendations. A real submit returns three timelines and no selected moment. The installed model kept no review spans.
Goal. Connect the page to the fixture endpoint, including loading, reset, errors, keyboard submit, and a Playwright characterization of the Hook.
Changes. The button is enabled when the service contract matches, including while the model is not loaded. The first request loads the model. The badge reads Synthetic fixture. Metadata still reports the fixture as unavailable. Gathering evidence disables a second submit. Start over clears the result. A failed request keeps the inputs, and Retry uses a new idempotency key. The work is local on fixture-hook and is not committed.
Verification.
npm test: 6 passed.npm run buildpassed, thennpm run test:shell: 11 passed. The new journey covers keyboard submit, the mocked winner (Courtyard Lantern recommended, North Gallery Supper fallback), insufficient evidence, and a 503 whose retry uses a new key.- One uncached API call returned HTTP 200 in 13.9 seconds:
insufficient_evidence, three restaurants, no recommendation, no accepted evidence, six rejected signals. - Chromium at
http://127.0.0.1:5173/submitted the preset, showed North Gallery Supper, Courtyard Lantern, and Platform Seats, showed “No moment selected,” opened evidence with no accepted quotes, and Start over restored the empty matrix.
Decisions. The winner proof is a mocked contract response. The installed model is not given precomputed quotes. The client timeout is 30 seconds. The measured cold request finished in 13.9 seconds.
Risks. A cold request near three excerpts can approach that 30-second limit. The page at /?layout=sample is still the labeled picture of a winner. It is not a scored visit.
HANDOFF update. Completed: fixture Hook proof. Next: your check below, then the bounded SerpApi client. Clock: deadline October 5, 2026 at 06:59 UTC. Feature freeze is build hour 19 of 24 and is not reached.
The API is on http://127.0.0.1:8000 and the page is on http://127.0.0.1:5173. Load that page fresh and submit the Indiranagar dinner preset. You should see three timelines and “No moment selected.”

Briefly inform the user about the task result and perform any follow-up actions (if needed). If there's no follow-ups needed, don't explicitly say that.
The old preview on port 4173 was stopped so the tests could serve a fresh build. I’m checking that the page and API you were asked to open are still running.
The preview on port 4173 stopped because it was shut down to serve a fresh build. That exit is from the stop signal, not from a failed test.
