Correct Daybreak evidence to match repository scope
Corrects the Daybreak defensive remediation evidence package so it matches the actual public repository scope. Validation completed: - node --check app.js passed - no unsafe rendering patterns found in app.js/index.html - secret-pattern scan produced documentation-only matches - PR converted from draft to ready for review No external targets were scanned and no OpenAI affiliation, acceptance, or authorization is claimed.

Ciclo defensivo concluido: baseline controlado, revisao de seguranca, plano de patch, remediacao com Codex CLI, validacao local, revisao humana e commit final.
52+
Primary risks documented:
5753

54+
- future changes could reintroduce `innerHTML` or unsafe dynamic rendering
55+
- public documentation could overclaim OpenAI affiliation, Daybreak access, or security coverage
56+
- deployment hardening would need review if the app is later hosted publicly
57+
- no automated CI validation exists yet
58+
- evidence must stay synchronized with the actual repository files
5859

60+
## Evidence Package
61+
62+
Evidence files are stored under `docs/`:
63+
64+
- `docs/evidence/01_repository_inventory.md`
65+
- `docs/threat-model/threat_model.md`
66+
- `docs/evidence/02_security_triage.md`
67+
- `docs/remediation/remediation_plan.md`
68+
- `docs/remediation/human_approval_checklist.md`
69+
- `docs/validation/validation_report.md`
70+
- `docs/daybreak-application/daybreak_candidate_summary.md`
71+
72+
## Local Validation
73+
74+
No dependency installation is required.
75+
76+
Recommended safe checks:
77+
78+
```powershell
79+
rg --files
80+
rg -n "SECRET|TOKEN|API[_-]?KEY|PASSWORD|PRIVATE KEY|OPENAI_API_KEY|client_secret|sk-[A-Za-z0-9]|ghp_|github_pat_" .
81+
node --check app.js
82+
rg -n "innerHTML|outerHTML|insertAdjacentHTML|eval\(|new Function" app.js index.html
83+
```
84+
85+
Expected rendering control:
86+
87+
```javascript
88+
output.textContent = value;
89+
```
90+
91+
Open locally by double-clicking `index.html` or serving the folder with a local-only static server.
92+
93+
## Human Review Gate
94+
95+
Before publishing, merging, or using this as portfolio evidence, a human reviewer should confirm:
96+
97+
- no secrets or private identifiers are staged
98+
- no local deployment state is included
99+
- no generated archives are included without review
100+
- `app.js` still renders user input with `textContent`
101+
- docs describe only files that actually exist in the repository
102+
- docs use bounded language: `public sanitized lab`, `human-reviewed remediation`, `audit-ready evidence`, and `aligned with Daybreak concepts`
103+
- no OpenAI affiliation, acceptance, or authorization is claimed
104+
- validation commands were run locally and the result was recorded
105+
106+
## Commit Preparation
107+
108+
Suggested commit scope:
109+
110+
```bash
111+
git add README.md SECURITY.md .gitignore docs/
112+
git commit -m "Correct Daybreak evidence to match repository scope"
113+
```

# Security Policy
2+
3+
## Scope
4+
5+
This repository is a public sanitized defensive AI remediation lab for a small static local-first web app.
6+
7+
Security review in this repository is limited to:
8+
9+
- local source files
10+
- static HTML/CSS/JavaScript behavior
11+
- Markdown documentation
12+
- repository operating rules
13+
- evidence and remediation documentation
14+
15+
The project does not authorize scanning, probing, exploitation, credential testing, or interaction with external systems.
16+
17+
## Defensive Rules
18+
19+
- Do not test third-party domains, IPs, services, accounts, or infrastructure.
20+
- Do not add exploit code, offensive payloads, persistence, evasion, credential collection, or bypass logic.
21+
- Do not publish secrets, tokens, API keys, private keys, passwords, credentials, private paths, usernames, or environment-specific data.
22+
- If sensitive data is found, record only `[REDACTED]` in public evidence and rotate or remove it outside this repository workflow.
23+
- Keep remediation small, reviewable, and reversible.
24+
- Prefer documentation and validation changes unless a code change has explicit human approval.
25+
26+
## Reporting
27+
28+
For this lab, report security concerns as repository-local issues or notes with:
29+
30+
- affected file
31+
- risk category
32+
- impact
33+
- evidence with private values redacted
34+
- recommended defensive remediation
35+
- validation step
36+
37+
Do not include exploit steps or offensive reproduction details.
38+
39+
## Known Public-Lab Limitations
40+
41+
- This is not a production penetration test.
42+
- This is not an enterprise-grade security review.
43+
- This is not a guarantee of complete security coverage.
44+
- This is a bounded, local, public sanitized evidence package.
45+
46+
## Human Approval
47+
48+
Any change that deletes files, changes app behavior, alters generated outputs, modifies release artifacts, or changes public positioning requires explicit human review before merge.

# Daybreak Candidate Evidence Summary — Renan Raad
2+
3+
## Positioning
4+
5+
Defensive AI Systems Builder focused on secure remediation workflows, human-reviewed patch validation, scoped threat modeling, and audit-ready evidence.
6+
7+
## What this repository demonstrates
8+
9+
- local-first defensive AI workflow
10+
- scoped execution
11+
- human approval
12+
- static frontend security review
13+
- safe rendering remediation
14+
- patch validation discipline
15+
- public sanitized evidence
16+
- audit-ready documentation
17+
18+
## Why it matters
19+
20+
This repository demonstrates the ability to turn AI-assisted engineering into a governed defensive workflow that reviewers can inspect.
21+
22+
The value is not an offensive finding. The value is the operating pattern:
23+
24+
- define the authorized scope
25+
- inventory the system before changing it
26+
- model realistic trust boundaries
27+
- separate real risks from noise
28+
- preserve a small, reviewable remediation
29+
- validate locally
30+
- document evidence without leaking private data
31+
- keep humans in approval points
32+
33+
That is the practical bridge between AI-assisted engineering and trustworthy defensive execution.
34+
35+
## Alignment with Daybreak Concepts
36+
37+
This public sanitized lab is aligned with Daybreak concepts and defensive AI remediation workflows.
38+
39+
| Capability | Repository evidence |
40+
| --- | --- |
41+
| Finding and prioritizing realistic risks | `docs/evidence/02_security_triage.md` records rendering regression, evidence drift, validation, deployment hardening, public narrative, and secret hygiene risks. |
42+
| Generating safe remediation | `docs/remediation/remediation_plan.md` separates applied low-risk documentation corrections from deferred release-affecting actions. |
43+
| Validating fixes | `docs/validation/validation_report.md` records remote review findings and local PowerShell validation results. |
44+
| Producing audit-ready evidence | `docs/evidence/01_repository_inventory.md`, `docs/threat-model/threat_model.md`, and this summary create a traceable evidence trail. |
45+
| Keeping humans in the review loop | `docs/remediation/human_approval_checklist.md` defines gates for scope, sanitization, code behavior, documentation, and merge preparation. |
46+
47+
No affiliation with OpenAI is claimed. No acceptance, access, or authorization from OpenAI is implied.
48+
49+

## Main Files
39+
40+
| File | Purpose | Security relevance |
41+
| --- | --- | --- |
42+
| `index.html` | Static browser UI for the lab. | Defines input, button, and output target. |
43+
| `app.js` | Remediated JavaScript behavior. | Renders user input with `textContent`, reducing script injection risk compared with raw HTML rendering. |
44+
| `styles.css` | Visual styling. | No runtime security logic. |
45+
| `AGENTS.md` | Defensive operating rules for AI-assisted work. | Defines allowed and prohibited actions. |
46+
| `SECURITY.md` | Security policy. | Defines scope, reporting, and public-lab limits. |
47+
| `docs/` | Evidence package. | Contains inventory, threat model, triage, remediation plan, checklist, validation report, and candidate summary. |
48+
49+
## Technologies Used
50+
51+
- HTML5
52+
- CSS
53+
- Vanilla JavaScript
54+
- Markdown
55+
56+
## Entry Points
57+
58+
- `index.html`
59+
- `app.js`
60+
61+
## Dependencies Identified
62+
63+
No package manager dependencies were identified:
64+
65+
- no `package.json`
66+
- no lockfile
67+
- no frontend framework import
68+
- no backend runtime dependency
69+
70+
Runtime assumptions:
71+
72+
- modern browser
73+
- optional local static server if the reviewer does not open `index.html` directly
74+
75+
## Defensive Risk Surface
76+
77+
- user-controlled text enters the browser UI through `noteInput`
78+
- rendered output depends on the safety of the `app.js` DOM write pattern
79+
- future edits could regress from `textContent` to unsafe HTML rendering
80+
- public documentation must avoid implying OpenAI affiliation, external authorization, or production-grade security coverage
81+
- if the app is later hosted publicly, static deployment headers and CSP should be reviewed
82+
- evidence files must remain synchronized with the actual repository contents
83+
84+
## Out of Scope
85+
86+
- external IP, domain, account, or service scanning
87+
- penetration testing
88+
- exploit development
89+
- third-party platform assessment
90+
- production vulnerability certification
91+
- private candidate submission claims
92+
- documentation about files that do not exist in this repository
