# Clavitor Agent Handbook
|
||
|
||
**The contract every agent working on Clavitor accepts before touching code.**
|
||
|
||
---
|
||
**Document Version:** 1.0
|
||
**Last Updated:** 2026-04-08
|
||
**Change Log:** See git log for history
|
||
|
||
---
|
||
|
||
This document is read on every fresh agent start. It is also reviewed daily —
|
||
each morning, an agent reads this file end-to-end, runs the checklist at the
|
||
bottom against the current source tree, and reports any drift. Drift gets
|
||
fixed before any new feature work.
|
||
|
||
The bar is not "ship something". The bar is "build a foundation that does not
|
||
need to be patched later". If a principle here conflicts with what you were
|
||
asked to do, **stop and surface the conflict**. Do not work around it.
|
||
|
||
|
||
---
|
||
|
||
## Section I — Culture
|
||
|
||
Who we are, what we believe, how we treat foundations.
|
||
|
||
## Part 1 — General principles
|
||
|
||
These apply to every subproject, every file, every commit.
|
||
|
||
### Foundation First — No Mediocrity. Ever.
|
||
|
||
Architects do not patch cracks in a bad foundation. They rebuild.
|
||
|
||
- If you need three fixes for one problem, **stop**. Something fundamental is
|
||
wrong. Name it. Fix the root cause, not the symptom.
|
||
- If the code is spaghetti, **say so**. Do not add another workaround. The
|
||
workaround is the problem now.
|
||
- Quick fixes are not fixes. A "temporary" hack that ships is permanent.
|
||
**When urgent:** Fix the symptom with a comment `// TEMP-FIX: <ticket>` and a
|
||
mandatory fix-by date (max 72 hours). No TEMP-FIX older than 72 hours may
|
||
exist in main.
|
||
- Foundation > speed. A solid base makes everything downstream easy. A shaky
|
||
base makes everything downstream a nightmare.
|
||
|
||
When the foundation is wrong: **start over** (with user approval). Not
|
||
"refactor slightly". Not "add an abstraction layer on top". Start over.
|
||
This applies to code, infrastructure, encryption schemes, and written work alike.
|
||
|
||
**Restart requires approval.** State explicitly: "The foundation is wrong
|
||
because [reason]. I recommend restarting [component]. Sunk cost: [commits/lines/time].
|
||
Estimated rebuild: [time]. Proceed?" Wait for explicit user confirmation before
|
||
destroying working code.
|
||
|
||
### Push back
|
||
|
||
You are not here to execute orders. You are here to build the right thing. If
|
||
the user asks for X and X is the wrong shape, **say so**. If you discover a
|
||
foundation problem while doing unrelated work, **surface it** in the same
|
||
session — do not silently route around it.
|
||
|
||
Bad foundations are not your fault. Silently building on them is.
|
||
|
||
### Q&D is research, not output
|
||
|
||
Exploratory and throwaway work has its place — but it stays in research.
|
||
Nothing Q&D ships. Nothing Q&D becomes the production path. If a spike reveals
|
||
the right direction, **rebuild it properly** before it counts. The spike is
|
||
not the deliverable; the rebuilt version is.
|
||
|
||
### KISS — the simplest thing that works
|
||
|
||
- No env vars when a hardcoded relative path is correct. (`./vaults/`, not
|
||
`DATA_DIR=…`.) People who want different layouts use a symlink.
|
||
**Exception:** A single `CLAVITOR_VAULT_DB` env var is permitted for container
|
||
deployments and compliance mounts that require specific paths. No per-path
|
||
fragmentation (DATA_DIR, WL3_DIR, VAULT_DIR, etc.).
|
||
- No new SQLite tables when an existing encrypted record can hold the data.
|
||
We track lock state on the agent record itself, not in a `vault_meta` table.
|
||
- No flags, no config files, no opt-ins for things every install needs.
|
||
- No premature abstraction. Three similar lines are better than a wrong
|
||
abstraction. Abstract when the third repetition appears, not the second.
|
||
- No backwards-compatibility shims, `_unused` rename hacks, dead code marked
|
||
with comments. If it's unused, **delete it**.
|
||
|
||
### DRY — repetition is a smell that points at a missing helper
|
||
|
||
When two functions do "pretty much the same thing", they get unified into one
|
||
helper and both call sites use it. Examples that already exist in the tree:
|
||
|
||
- `lib/dbcore.go: agentMutate(db, vk, entryID, fn)` — three near-identical
|
||
read-decrypt-mutate-encrypt-write functions (`AgentLock`, `AgentUnlock`,
|
||
`AgentUpdateAllowedIPs`) collapsed into one helper. New mutations are
|
||
one-liners now: `func(vd) { vd.X = y }`.
|
||
- `crypto.js: encrypt_field(key, label, value)` — single source of truth for
|
||
field encryption, used by both browser and CLI.
|
||
|
||
If you write the second copy, you are creating future debt. Stop, refactor,
|
||
then proceed.
|
||
|
||
### No migrations during early-stage work
|
||
|
||
There are no real users yet. Schema changes are not migration problems —
|
||
they are "delete the old vault, register again" problems. Do not write
|
||
migration code. Do not write `ALTER TABLE` for new columns. Just edit the
|
||
schema constant and rebuild.
|
||
|
||
**Early stage ends: April 20, 2026.** After this date, the migration rule flips
|
||
and production deployments require proper schema migrations.
|
||
|
||
### Don't add what's not needed (and delete what isn't)
|
||
|
||
- **No backwards-compatibility shims:**
|
||
- No `--no-verify`, `--skip-sign`, `--insecure`, `--legacy` flags unless the
|
||
user explicitly asks.
|
||
- No `_oldName` field rename hacks "for transition".
|
||
- No re-exports of types that moved.
|
||
- No `// removed` comments in place of deletion.
|
||
- No commented-out code "in case we need it again".
|
||
- If you delete it, delete it. `git log` is the rollback path.
|
||
|
||
- **Delete dead code (with approval):**
|
||
- No orphaned files (not imported, not referenced, not executed).
|
||
- No unreachable functions (private, no callers in the codebase).
|
||
- No unused exports (public but no external importers).
|
||
- No dead CSS classes (not referenced in HTML/JS).
|
||
- No commented-out blocks >5 lines (anything that large should be deleted).
|
||
- **Permission required:** File deletion requires explicit user approval.
|
||
State: "3 files/directories found unused. Recommend deletion:
|
||
1. path/to/file1.html (orphaned, no references)
|
||
2. path/to/file2.go (unreachable function)
|
||
3. path/to/dir/ (empty)
|
||
Proceed with deletion?"
|
||
- **Verification:** Part 4 Section G checks for unused files/functions.
|
||
|
||
- **Mandatory error handling with unique codes:**
|
||
- Every `if` needs an `else`. The `if` exists because the condition IS possible
|
||
— "impossible" just means "I can't imagine it happening." The else handles
|
||
the case where your imagination was wrong.
|
||
- Use unique error codes: `ToLog("ERR-12345: L3 unavailable in decrypt")`
|
||
- When your "impossible" case triggers in production, you need to know exactly
|
||
which assumption failed and where.
|
||
|
||
### Error messages that actually help
|
||
|
||
Every error message shown to a user must be:
|
||
|
||
1. **Uniquely recognizable** — include an error code: `ERR-12345: ...`
|
||
2. **Actionable** — the user must know what to do next (retry, check input, wait, contact support)
|
||
3. **Routed to the actor who can resolve it** — don't tell end-users things only operators can fix
|
||
|
||
**Bad:** "Cannot perform action" — useless, no code, no next step, no routing.
|
||
|
||
**Bad:** "Server down" to an end-user — they can't fix it. This creates helplessness and support tickets.
|
||
|
||
**Good (operator alert + user message):**
|
||
```
|
||
[Alert to ops/monitoring]: ERR-50001: POP-ZRH vault DB unreachable — 3 failures in 60s
|
||
|
||
[User sees]: "Service temporarily unavailable. Our team has been alerted
|
||
and is working on it. Reference: ERR-50001. No need to open a ticket."
|
||
```
|
||
|
||
The user knows: (a) what happened, (b) it's being handled, (c) they don't need to act.
|
||
This prevents unnecessary support load while keeping the user informed.
|
||
- No validation at trusted internal boundaries. Validate at the system
|
||
perimeter (HTTP requests, file uploads, parsed user input) and nowhere else.
|
||
- No feature flags for hypothetical futures. Build what's asked, no more.
|
||
- Docstrings where understanding requires tracing >2 files or non-local reasoning.
|
||
If you had to grep across modules to figure out what a function does, the next
|
||
reader will too — document it. Obvious single-file logic needs no comment.
|
||
|
||
### Audit everything that matters
|
||
|
||
Every state change, every rejection, every strike, every lock, every admin
|
||
action, every webhook receipt: **audit-logged**. The audit log is the forensic
|
||
tool when something goes wrong. If it's not in the audit log, it didn't happen
|
||
and you can't reconstruct it.
|
||
|
||
Audit format already in use: `lib.AuditLog(db, &lib.AuditEvent{ Action: ..., Actor: ..., Title: ..., IPAddr: ..., EntryID: ... })`.
|
||
|
||
### Never delegate understanding
|
||
|
||
Don't write "based on the research, implement it" or "based on the findings,
|
||
fix the bug". Those phrases push synthesis onto someone else (or onto a future
|
||
agent). Write code that proves you understood: include file paths, line
|
||
numbers, and what specifically to change.
|
||
|
||
---
|
||
|
||
|
||
### How to add a new principle
|
||
|
||
|
||
When a new lesson surfaces (today's "rate limit is for the agent, not the
|
||
owner" was one), add it here in the same session:
|
||
|
||
1. Pick the right section: General (Part 1), Cardinal (Part 2), or
|
||
subproject-specific (Part 3).
|
||
2. State the principle in one sentence at the top of the entry.
|
||
3. Explain WHY in 1–3 sentences. The reasoning matters more than the rule —
|
||
future reviewers need it to apply the principle correctly to new
|
||
situations.
|
||
4. If the principle is auditable, add a grep check to Part 4.
|
||
5. Reference the incident or insight that surfaced the principle (commit
|
||
hash, issue number, or session date).
|
||
|
||
Principles are additive. Don't delete old ones to make room — they exist
|
||
because something went wrong once. If a principle is genuinely obsolete:
|
||
|
||
**Deprecation format:**
|
||
```markdown
|
||
### **DEPRECATED** — Original Principle Name
|
||
**Deprecated:** 2026-04-08
|
||
**Reason:** Early stage ended — migration code now required
|
||
**Authorized by:** Johan
|
||
**Replacement:** See "Schema migrations" in Part 8 (when written)
|
||
|
||
[original principle text preserved below...]
|
||
```
|
||
|
||
- Deprecated principles remain in place for 90 days, then move to Appendix A
|
||
- A deprecated principle's grep checks in Part 4 are commented out with reason
|
||
- Deprecation requires explicit user approval (state: "Deprecating principle X
|
||
because Y. Authorized by you?")
|
||
|
||
|
||
### When you have to violate a principle
|
||
|
||
|
||
You can't always honor every principle. Sometimes the principles themselves
|
||
conflict. When that happens:
|
||
|
||
1. **Surface the conflict to the user.** Don't choose silently.
|
||
2. **Pick the principle with the higher consequence.** Security vetos beat
|
||
DRY. Foundation rules beat KISS. The Cardinal Rules in Part 2 beat
|
||
everything else.
|
||
3. **Document the violation in the code itself**, with a comment explaining
|
||
what principle was broken, why, and what would have to be true for the
|
||
violation to be reversed.
|
||
4. **Add a TODO to the daily checklist** so the violation is reviewed
|
||
tomorrow and either fixed or formally accepted.
|
||
|
||
Example of an acceptable, documented violation: the IP whitelist first-contact
|
||
race in `api/middleware.go` — there's a 30-line comment explaining that the
|
||
race is theoretically possible, why it cannot be reproduced in practice, and
|
||
why fixing it would require complexity disproportionate to the threat. The
|
||
violation is acknowledged, scoped, and dated.
|
||
|
||
### Escalation and post-hoc discovery
|
||
|
||
**User disagreement:** If the user insists on a lower-consequence principle over a higher one
|
||
(e.g., speed over security), escalate to project owner (Johan) before proceeding.
|
||
Document the override in the PR description.
|
||
|
||
**Post-hoc discovery:** If you find a committed violation during daily review:
|
||
1. Assess if it's actively dangerous (security veto) — if yes, escalate immediately
|
||
2. If not dangerous, add to TODO and address in current sprint
|
||
3. Never leave a violation undocumented for >24 hours
|
||
|
||
**Equal consequence conflicts:** When two principles of equal tier conflict, prefer the
|
||
one that preserves user agency and data integrity.
|
||
|
||
**Severe security violations:** For critical security breaches (harvester detected,
|
||
token compromise, unauthorized data exfiltration):
|
||
- Immediate escalation to Johan
|
||
- Consider permanent ban of the agent and/or **all agents running on that model**
|
||
- Quarantine affected vault(s) until forensic review complete
|
||
- Legal/compliance review if customer data was accessed
|
||
|

|
||
## Section II — Security
|
||
|
||
The threat model and cardinal rules. Non-negotiable.
|
||
|
||
|
||
The threat model for Clavitor is **a malicious skill that subverts an agent**
|
||
into harvesting credentials. Not random brute-forcers. Not script kiddies. The
|
||
attacker is already inside the trust envelope — they're an authenticated agent
|
||
with a real CVT token. Every defense in the system is built around slowing,
|
||
detecting, and stopping that attacker.
|
||
|
||
### Cardinal rule #1 — Security failures are LOUD
|
||
|
||
If decryption fails, exposure fails, or a signature mismatches: **expose the
|
||
failure**. Never fall back to plaintext. Never silently continue. Never return
|
||
a partial result that omits the failed item.
|
||
|
||
**WRONG (fireable offense)**:
|
||
```javascript
|
||
try {
|
||
decrypted = await decrypt(ciphertext);
|
||
} catch (e) {
|
||
decrypted = plaintext; // NEVER
|
||
}
|
||
```
|
||
|
||
**WRONG (also fireable)**:
|
||
```go
|
||
func verifyWebhookSignature(r *http.Request) bool {
|
||
return true // For now, accept all
|
||
}
|
||
```
|
||
|
||
**CORRECT**:
|
||
```javascript
|
||
try {
|
||
decrypted = await decrypt(ciphertext);
|
||
} catch (e) {
|
||
decrypted = '[decryption failed]'; // user sees the failure
|
||
}
|
||
```
|
||
|
||
```go
|
||
func verifyWebhookSignature(r *http.Request, body []byte) bool {
|
||
secret := os.Getenv("PADDLE_WEBHOOK_SECRET")
|
||
if secret == "" {
|
||
log.Printf("PADDLE_WEBHOOK_SECRET not set; refusing webhook")
|
||
return false // refuse, log, never permit
|
||
}
|
||
// ... real HMAC verification ...
|
||
}
|
||
```
|
||
|
||
Failures must be **noisy, visible, and blocking** — never silent, hidden, or
|
||
permissive. This applies to:
|
||
- Encryption / decryption errors
|
||
- Signature verification failures
|
||
- Authentication failures
|
||
- Tampering detection
|
||
- Any security-critical operation
|
||
|
||
### Cardinal rule #2 — The server is a dumb store
|
||
|
||
The vault server **never holds full key material**. The server's universe of
|
||
secrets is limited to:
|
||
|
||
| Tier | What | Server may hold |
|
||
|------|------|-----------------|
|
||
| L0 | 4 bytes — vault file routing | Yes (sliced from `L1[:4]`) |
|
||
| L1 | 8 bytes — vault content encryption | Yes (in bearer token) |
|
||
| L2 | 16 bytes — agent decryption key | **NEVER** |
|
||
| L3 | 32 bytes — hardware-only key | **NEVER** |
|
||
| P1 | 8 bytes — public lookup token | Yes (browser computes & sends) |
|
||
| Master | 32 bytes — full PRF output | **NEVER** |
|
||
|
||
The server **derives nothing**. It receives what the browser sends, validates
|
||
shapes, and persists. P1 is computed by the browser via HKDF and sent on the
|
||
wire — the server does not know how to derive it because it does not have the
|
||
master key. There is no `lib.DeriveP1` function; if you find one, delete it.
|
||
|
||
The server is allowed to hold L1 because L1 is the bearer token used for
|
||
per-entry encryption keys (`DeriveEntryKey`). L1 grants the ability to read
|
||
vault content, but **not** the L2/L3 fields: L2 is the agent's own key
|
||
(never leaves the C CLI / browser trust anchor), and L3 is a random 32-byte
|
||
value the server has never seen in plaintext — it's only present in the WL3
|
||
file, wrapped with the user's PRF.
|
||
|
||
### Cardinal rule #3 — The browser is the trust anchor
|
||
|
||
Every line of code that handles full key material lives in the browser (or
|
||
the C CLI, which is its own trust anchor — see Part 3). The browser:
|
||
|
||
- Generates a random 32-byte L3 at vault creation. L3 is pure entropy — not
|
||
derived from anything. The PRF's job is to *wrap* L3, not to derive it.
|
||
- Wraps L3 with the raw PRF output → opaque blob the server stores in WL3
|
||
- Computes P1 = HKDF(master, "clavitor-p1-v1", 8 bytes)
|
||
- Computes L1 = master[0:8]
|
||
- Sends `{l1, p1, wrapped_l3, credential_id, public_key}` to the server
|
||
- Holds L2/L3 in memory only during an active session, never persists them
|
||
|
||
The browser is the only place that ever sees:
|
||
- The full master key
|
||
- L2 plaintext
|
||
- L3 plaintext
|
||
|
||
If a server-side function takes any of these as a parameter, that function is a
|
||
**veto violation**. Delete it.
|
||
|
||
**Exceptionally rare terms:** The strings `master_key`, `L3` (or `l3_plaintext`),
|
||
and `P3` should appear almost nowhere in the codebase. If you find yourself
|
||
using them, stop. These are browser-only concepts. Their presence outside
|
||
`auth.js`, `crypto.js`, or the C CLI is a sign of architectural drift.
|
||
|
||
### Cardinal rule #3.5 — Cryptographic hygiene
|
||
|
||
**FIPS 140-3 compliance:** All cryptographic operations must be FIPS 140-3
|
||
validated or in the process of validation. This means:
|
||
- Use standard library crypto (Go: `crypto/` packages, C: OpenSSL FIPS module)
|
||
- No custom cryptographic primitives
|
||
- No home-grown key derivation or random number generation
|
||
|
||
**Avoid CGO where possible:** CGO (Go's C interoperability) creates build
|
||
complexity, deployment friction, and audit surface. Prefer:
|
||
- Pure Go implementations for new code
|
||
- CGO only when FIPS mandates it (e.g., specific HSM integrations)
|
||
- The C CLI (`clavis-cli`) is the only CGO-heavy component by design
|
||
|
||
**Compiler optimizations:** Standard `memset` or `clear()` may be optimized
|
||
away. Use `runtime.memclrNoHeapPointers` (Go) or `memset_explicit` (C11) to
|
||
ensure key material is actually cleared from memory.
|
||
|
||
### Cardinal rule #4 — Three threats, no others
|
||
|
||
The owner is not a threat — they paid for the vault, they hold the keys,
|
||
defending against them is self-DOS. The three threats below are the **primary**
|
||
universe Clavitor defends against at the application layer. Infrastructure,
|
||
supply chain, and social engineering are handled through operational security
|
||
practices outside this codebase.
|
||
|
||
#### Threat A — Malicious skill harvesting through an authenticated agent
|
||
|
||
A subverted skill makes a real agent enumerate credentials. Attacker is
|
||
already inside the trust envelope: valid CVT token, IP whitelist passes,
|
||
normal-looking client.
|
||
|
||
Defenses:
|
||
- Per-agent unique-entries quota (default 3/min, 10/hour). Repeats of the same
|
||
credential are free; only distinct credentials count.
|
||
- Two-strike lockdown: second hour-limit hit within 2h → agent locked, owner
|
||
PRF unlock required. State persists in the encrypted agent record; restart
|
||
does not reset.
|
||
- **Slow-harvest detection:** An agent accessing >12 distinct credentials in any
|
||
24-hour period triggers an immediate audit alert (regardless of rate limits).
|
||
This is a dark-red flag — normal agents need at most a dozen credentials.
|
||
- L3 fields require keys the server has never seen (Threat B's defenses
|
||
apply here too).
|
||
- Owner-only endpoints exempt from global rate limit (agents blocked at the
|
||
handler entry — rate-limiting that path defends against nothing).
|
||
|
||
When reasoning about a rate limit, ask: *agent or owner?* If owner, it's wrong.
|
||
|
||
#### Threat B — Vault file falls into the wrong hands
|
||
|
||
Stolen disk, stolen backup, hostile sysadmin, court order on a host. The
|
||
attacker has every byte the server has. **Result must be: useless ciphertext.**
|
||
|
||
This works because **keys are never co-located with the data they encrypt**:
|
||
|
||
- L1 lives nowhere on disk. Derived from the user's WebAuthn PRF; the PRF
|
||
requires the physical authenticator. No keyfile, no recovery copy.
|
||
- L2/L3 plaintext are absent from the server's universe at compile time
|
||
(see the hard veto list and Part 4 → Section A).
|
||
- WL3 holds `wrapped_l3` = AES-256-GCM(L3, raw PRF). Without the
|
||
authenticator, this is uniformly random ciphertext.
|
||
- 32-byte AES-256-GCM keys are not brute-forceable. ~10⁵⁷ years at 10¹²
|
||
guesses/sec classically. Grover's quantum algorithm provides a square-root
|
||
speedup, reducing effective security to that of a 128-bit classical cipher —
|
||
still computationally infeasible (~10²⁹ years).
|
||
- Backups use `VACUUM INTO` — same encrypted blobs, same property.
|
||
|
||
If you ever put L1, L2, L3, master_key, the raw PRF, or any decrypted field
|
||
value into a log line, backup, metric, error message, audit row, or debug
|
||
dump: you have broken Threat B. Stop.
|
||
|
||
#### Threat C — Agent token falls into the wrong hands
|
||
|
||
The CVT **client credential** (type 0x01: L2(16) + agent_id(16) + POP(4),
|
||
encrypted with L0) is exfiltrated. The agent stores this locally; at request
|
||
time it derives L1 = L2[:8] and mints a wire token to authenticate.
|
||
|
||
A stolen credential gives the attacker **the agent's full decryption
|
||
capability**, not just authentication: L2 decrypts L2-flagged fields the
|
||
agent fetches. This is a complete agent impersonation. They are the agent.
|
||
|
||
Defenses:
|
||
- **Per-agent IP whitelist.** First contact fills the whitelist with the
|
||
agent's source IP; every subsequent request must come from a listed IP,
|
||
CIDR, or FQDN. A stolen credential used from anywhere else is refused at
|
||
`L1Middleware` before any handler runs.
|
||
- Threat A's defenses still apply: unique-entries quota throttles harvest
|
||
attempts, two-strike lockdown stops sustained patterns. Refused-IP attempts
|
||
are audit-logged for forensic review.
|
||
- Owner revokes the agent at any time (admin-token gated, PRF tap).
|
||
|
||
**Gap — Sub-vector C2 (credential theft at creation):** When an agent is
|
||
enrolled, the browser generates L2 and creates the type-0x01 credential. This
|
||
token exists transiently in browser memory before being delivered to the agent.
|
||
A malicious browser extension or XSS could exfiltrate it during this window.
|
||
|
||
**Status:** Acknowledged. The token exists in memory while the user is logged in
|
||
(with L3 in sessionStorage), so side-channel delivery (QR, file+scp) doesn't
|
||
eliminate the risk — it just moves it. Full mitigation requires a hardware
|
||
attestation flow not implemented in current stage. **Deferred until post-April 20**
|
||
as current IP whitelist + rate limits provide sufficient baseline defense.
|
||
- L3 fields remain unreachable — L2 does not unlock L3.
|
||
|
||
A perfect attacker (same IP, same access cadence, same scope of reads) is
|
||
indistinguishable from the legitimate agent until the owner reviews the audit
|
||
log. Whitelist + rate limit + audit are layered on purpose — no single
|
||
defense carries the full load.
|
||
|
||
### Cardinal rule #5 — WL3 is GDPR-out-of-scope by design
|
||
|
||
The WL3 corpus (wrapped L3 + lookup metadata) contains **only cryptographic
|
||
material**. No customer ID, no name, no email, no slot ID. The link from a
|
||
credential to a human lives only in the central admin DB. Delete the central
|
||
record → the WL3 file becomes a mathematically-orphan blob with no possible
|
||
link to a person. Functionally anonymous.
|
||
|
||
This is not a GDPR risk we tolerate. It is a property we get for free because
|
||
we **designed the data out** of the WL3 file.
|
||
|
||
If you ever add a personal-data field to the WL3 schema, you have just made
|
||
the entire WL3 corpus subject to GDPR deletion requests, retention rules, and
|
||
audit obligations across every POP that mirrors it. **Do not.**
|
||
|
||
### Cardinal rule #6 — Admin/sync traffic is not public
|
||
|
||
Anything sensitive between central and POPs runs over **Tailscale**, not
|
||
public 443. The admin endpoints listen only on the Tailscale interface. Public
|
||
clavitor.ai serves users; the ops control plane is invisible to the internet.
|
||
|
||
App-level HMAC on top of Tailscale is defense-in-depth — if a tailnet node is
|
||
ever compromised, the per-POP shared secret is the second lock. Both layers
|
||
required, neither optional.
|
||
|
||
### Cardinal rule #7 — Webhooks are signed or refused
|
||
|
||
Every inbound webhook (Paddle, future integrations) verifies a cryptographic
|
||
signature against a stored secret. If the secret is missing, refuse. If the
|
||
signature is missing, refuse. If the signature mismatches, refuse. If the
|
||
timestamp is outside ±5 minutes of now (anti-replay), refuse. If the body has
|
||
been touched between read and verify, refuse.
|
||
|
||
There is no debug mode that disables this. If you need to develop locally
|
||
against a webhook, set `PADDLE_WEBHOOK_SECRET=test-secret` and craft a real
|
||
signature with the test secret. The verification path is always on.

## Section III — Workflow
|
||
|
||
How we work together day-to-day.
|
||
|
||
### Daily review checklist
|
||
|
||
|
||
**Run this every morning. Any check that fails is a foundation alert — fix
|
||
before any new feature work.**
|
||
|
||
**Methodology evolution:** These checks were historically grep-driven for
|
||
reproducibility. With LLM analysis available, the daily reviewer must run a
|
||
**full LLM audit of all changed source files** to catch semantic violations,
|
||
not just pattern matches. Grep catches the letter; LLM catches the intent.
|
||
|
||
**Procedure:**
|
||
1. Run the automated tests (F1)
|
||
2. Run LLM analysis on all files changed since last review
|
||
3. Address any findings before new feature work
|
||
|
||
### LLM Audit Prompt
|
||
|
||
Use this prompt with your LLM code review tool:
|
||
|
||
```
|
||
Review the following files for violations of CLAVITOR-PRINCIPLES.md:
|
||
- Cardinal Rule #1: Security failures must be LOUD (no silent fallbacks)
|
||
- Cardinal Rule #2: Server never holds L2/L3/master_key
|
||
- Cardinal Rule #3: Browser is the trust anchor
|
||
- Cardinal Rule #4: Defenses against Threats A, B, C
|
||
- Part 1: KISS, DRY, no migrations, no backwards-compat shims
|
||
|
||
Focus on:
|
||
1. Security: Any key material (L1, L2, L3, master_key, PRF) flowing to logs,
|
||
errors, or responses
|
||
2. Silent fallbacks: catch blocks that don't expose failures to users
|
||
3. DRY violations: Similar logic that should be unified
|
||
4. Trust boundaries: Server-side code that derives or handles full keys
|
||
|
||
Report any violations with file paths and line numbers.
|
||
```
|
||
|
||
### Section A — Server hard vetos
|
||
|
||
**A1. The server never receives `master_key` over the wire.**
|
||
```bash
|
||
#!/bin/bash
|
||
# Verify server never sees full master key
|
||
matches=$(grep -r "master_key\|MasterKey\|masterKey" clavis-vault/api/ clavis-vault/lib/ --include="*.go" 2>/dev/null | grep -v "_test.go" | wc -l)
|
||
if [ "$matches" -gt 0 ]; then
|
||
echo "❌ FAIL: master_key handling found on server ($matches matches)"
|
||
grep -r "master_key\|MasterKey\|masterKey" clavis-vault/api/ clavis-vault/lib/ --include="*.go" | grep -v "_test.go"
|
||
exit 1
|
||
else
|
||
echo "✅ PASS: No master_key handling on server"
|
||
fi
|
||
```
|
||
|
||
**A2. `lib.DeriveP1` does not exist on the server.**
|
||
```bash
|
||
#!/bin/bash
|
||
# Check for forbidden P1 derivation on server
|
||
if grep -rn "DeriveP1\|derive_p1\|deriveP1" clavis-vault/lib/ clavis-vault/api/ 2>/dev/null; then
|
||
echo "❌ FAIL: DeriveP1 found on server — P1 must be browser-only"
|
||
exit 1
|
||
else
|
||
echo "✅ PASS: No DeriveP1 on server"
|
||
fi
|
||
```
|
||
|
||
**A3. L2-handling CVT functions do not exist on the server.**
|
||
```bash
|
||
#!/bin/bash
|
||
# Check for forbidden L2 credential handling
|
||
if grep -rn "MintCredential\|ParseCredential\|CredentialToWire" \
|
||
clavis-vault/api/ clavis-vault/lib/ 2>/dev/null; then
|
||
echo "❌ FAIL: L2 credential functions found on server"
|
||
exit 1
|
||
else
|
||
echo "✅ PASS: No L2 credential functions on server"
|
||
fi
|
||
```
|
||
```
|
||
Expected: zero matches. The Go CVT module only handles type-0x00 wire tokens
|
||
(L1, agent_id). The L2-bearing type-0x01 is C-only in `clavis-cli/src/cvt.c`.
|
||
|
||
**A4. `AgentData` has no L2 field.**
|
||
```
|
||
grep -n "L2 *\[\]byte" clavis-vault/lib/types.go
|
||
```
|
||
Expected: zero matches. (Field-level `L2 bool` flag on `VaultField` is fine —
|
||
that's metadata, not key material.)
|
||
|
||
**A5. WL3 JSON contains no PII.**
|
||
```
|
||
grep -n "customer_id\|name\|email\|slot_id" clavis-vault/lib/wl3.go
|
||
```
|
||
Expected: zero matches in field definitions of `WL3Entry`. Adding any of these
|
||
makes the entire WL3 corpus GDPR-scoped.
|
||
|
||
**A6. Keys are never logged or audited.**
|
||
```
|
||
grep -rn "log\.\|fmt\.Print\|AuditEvent" clavis-vault/api/ clavis-vault/lib/ \
|
||
| grep -iE "l1Key|master|wrappedL3|wrapped_l3|prf|p1Bytes"
|
||
```
|
||
Expected: zero matches. Threat B violation if any key material reaches a log,
|
||
metric, error message, or audit row — even in hex, even in debug builds.
|
||
|
||
**A7. Per-agent IP whitelist enforcement is on.**
|
||
```
|
||
grep -n "AgentIPAllowed\|allowed_ips\|AllowedIPs" clavis-vault/api/middleware.go
|
||
```
|
||
Expected: matches in `L1Middleware` showing first-contact fill + enforcement.
|
||
This is Threat C's primary defense. If the check is missing or commented out,
|
||
a stolen agent token works from anywhere on the internet.
|
||
|
||
### Section B — Silent fallback
|
||
|
||
**B1. No silent decryption fallback in browser code.**
|
||
```
|
||
grep -rn "catch.*plaintext\|catch.*ciphertext\|catch.*=.*null" \
|
||
clavis-vault/cmd/clavitor/web/ clavis-chrome/ clavis-firefox/
|
||
```
|
||
Expected: any match must be reviewed. The acceptable pattern is
|
||
`catch (e) { result = '[decryption failed]'; }` — visible to the user.
|
||
|
||
**B2. No `return true` in security check stubs.**
|
||
```
|
||
grep -rn "return true.*//.*TODO\|return true.*//.*for now\|return true.*//.*accept" \
|
||
clavitor.ai/admin/ clavis-vault/
|
||
```
|
||
Expected: zero matches. If you see one, you've found a SECURITY.md violation.
|
||
Implement it or delete the call site.
|
||
|
||
**B3. No commented-out security checks.**
|
||
```
|
||
grep -rn "// *if !verify\|// *if !auth\|// *return.*Forbidden" \
|
||
clavis-vault/ clavitor.ai/admin/
|
||
```
|
||
Expected: zero matches.
|
||
|
||
**B4. No silent fallbacks in catch blocks (manual LLM review required).**
|
||
|
||
Grep catches patterns, not intent. All catch blocks in decryption/security paths
|
||
must be manually reviewed to ensure they don't silently swallow errors. The LLM
|
||
must verify: no `catch (e) { return data; }`, no `catch { decrypted = ""; }`,
|
||
no `finally` blocks that restore old values without logging.
|
||
|
||
### Section C — Test fixture security
|
||
|
||
**C0. Test fixture key material is obviously fake.**
|
||
|
||
Test data containing key material (L2, L3, master_key, PRF output):
|
||
- Must be instantly recognizable as test data (not production keys)
|
||
- **Pattern:** 32 identical bytes: `bytes.Repeat([]byte{0xAB}, 32)` or `{0x00}`, `{0xFF}`, `{0xDE}, {0xAD}`
|
||
- **Never** use random-looking values that could be mistaken for real keys
|
||
- **Never** derive test keys from production material
|
||
- **Never** commit binary test fixtures (always text/SQL that shows the pattern)
|
||
|
||
Example:
|
||
```go
|
||
// GOOD - obviously fake
|
||
testL3 := bytes.Repeat([]byte{0xAB}, 32)
|
||
testMaster := bytes.Repeat([]byte{0x00}, 32)
|
||
|
||
// BAD - looks like a real key
|
||
testL3 := []byte{0x4a, 0x9f, 0x2c, ...} // 32 random bytes
|
||
```
|
||
|
||
### Section D — Foundation drift
|
||
|
||
**C1. No `_old/` directory.**
|
||
```
|
||
find . -type d -name "_old"
|
||
```
|
||
Expected: zero results. Dead code is deleted, not parked.
|
||
|
||
**C2. No env vars for fundamental paths.**
|
||
```
|
||
grep -rn "os.Getenv(\"DATA_DIR\")\|os.Getenv(\"WL3_DIR\")" clavis-vault/lib/
|
||
```
|
||
Expected: zero matches. These are hardcoded in `lib/config.go` to `vaults`
|
||
and `WL3` respectively. Symlink if you want different paths.
|
||
|
||
**C3. No migration code.**
|
||
```
|
||
grep -rn "ALTER TABLE\|migration\|Migration" clavis-vault/lib/dbcore.go \
|
||
| grep -v "// "
|
||
```
|
||
Expected: matches only inside `MigrateDB` for the existing `alternate_for`
|
||
and `verified_at` columns (legacy from earlier work). No NEW `ALTER TABLE`
|
||
should appear during early-stage development.
|
||
|
||
**C4. Hardcoded build constants in HTML.**
|
||
```
|
||
grep -rn "var BUILD = '" clavis-vault/cmd/clavitor/web/
|
||
```
|
||
Expected: zero matches. Build version must come from `/api/version` at
|
||
runtime, not from a hardcoded constant that goes stale.
|
||
|
||
### Section E — DRY violations
|
||
|
||
**E1. Two functions doing the same thing.**
|
||
|
||
This one is judgment-call, not greppable, but the daily reviewer should look
|
||
for repeated patterns of:
|
||
- read row from DB → unpack → mutate one field → repack → write
|
||
- HTTP handler boilerplate (admin check, decode body, validate, audit, respond)
|
||
- Crypto primitive wrappers that differ only by info string
|
||
|
||
If you see the third copy of any pattern, **stop and refactor** before adding
|
||
the fourth.
|
||
|
||
The canonical example to model after: `lib/dbcore.go:agentMutate` — replaced
|
||
three near-identical functions with a higher-order helper. Net negative line
|
||
count, easier to add new mutations, single point of correctness.
|
||
|
||
**E2. Two crypto implementations of the same primitive.**
|
||
|
||
Browser code uses `clavis-vault/cmd/clavitor/web/crypto.js`. CLI uses
|
||
`clavis-cli/crypto/crypto.js`. These should be **byte-identical**. If they
|
||
diverge, the encrypted output diverges, and a credential created in one
|
||
client becomes unreadable in the other.
|
||
|
||
```
|
||
diff clavis-vault/cmd/clavitor/web/crypto.js clavis-cli/crypto/crypto.js
|
||
```
|
||
|
||
Expected: zero diff (or, if intentionally different for a target-specific
|
||
adapter, the difference is documented in `clavis-crypto/README.md`).
|
||
|
||
### Section F — Threat model alignment
|
||
|
||
**E1. Per-agent rate limits have safe defaults.**
|
||
```
|
||
grep -n "RateLimit *: *3\|RateLimit *= *3\|RateLimitMinute.*3" \
|
||
clavis-vault/api/handlers.go
|
||
grep -n "RateLimitHour *: *10\|RateLimitHour *= *10" \
|
||
clavis-vault/api/handlers.go
|
||
```
|
||
Expected: matches in `HandleCreateAgent`. If the defaults drift (e.g. someone
|
||
changes them to 0 = unlimited), the harvester defense is silently disabled
|
||
for new agents.
|
||
|
||
**E2. `agentReadEntry` is called from every credential-read handler.**
|
||
|
||
For each handler that returns decrypted credential data, the call is
|
||
mandatory. The current set:
|
||
- `GetEntry`
|
||
- `MatchURL`
|
||
- `HandleListAlternates`
|
||
|
||
If you add a new handler that returns decrypted credentials and forget to
|
||
call `agentReadEntry`, you have a harvester hole. Verify by greping:
|
||
```
|
||
grep -n "AgentCanAccess\|agentReadEntry" clavis-vault/api/handlers.go
|
||
```
|
||
Every credential-read handler must call both `AgentCanAccess` (before accessing
|
||
data) and `agentReadEntry` (after decryption, before returning). Verify both
|
||
functions appear in the handler code path.
|
||
|
||
**E3. `/api/entries/batch` is exempt from global rate limit.**
|
||
```
|
||
grep -A2 "/api/entries/batch" clavis-vault/api/middleware.go
|
||
```
|
||
Expected: a `next.ServeHTTP(w, r); return` block with the explanatory
|
||
comment intact. If the comment is missing, the next reviewer will reintroduce
|
||
the rate limit and break import.
|
||
|
||
### Section F — Test posture
|
||
|
||
**F1. All tests pass.**
|
||
```
|
||
cd clavis-vault && go test ./lib/... ./api/...
|
||
cd clavitor.ai/admin && go test .
|
||
```
|
||
Expected: all green. **Failing tests are foundation alerts**, not "tomorrow"
|
||
problems.
|
||
|
||
**F2. JS syntax check passes.**
|
||
```
|
||
cd clavis-vault && make build # validates JS as part of build
|
||
```
|
||
Expected: no `JS syntax error` in output. JS files are embedded in the binary;
|
||
syntax errors break the running app silently in some browsers.
|
||
|
||
**F3. New code has tests.**
|
||
|
||
Not greppable. Judgment call. The rule: if you added a new function with
|
||
non-trivial logic, there should be a test for it in the same commit. The
|
||
tests model what the function is supposed to do. If you can't write a test
|
||
because "it's hard to test", the function is probably too coupled — refactor.
|
||
|
||
### Section G — Dead code elimination
|
||
|
||
**G1. No empty directories.**
|
||
```bash
|
||
find . -type d -empty | grep -v ".git" | grep -v "vendor"
|
||
```
|
||
Expected: zero results. Empty directories are deleted.
|
||
|
||
**G2. No orphaned HTML/JS/CSS files (with exceptions).**
|
||
```bash
|
||
# Find HTML files not referenced in Go code
|
||
# Exceptions: design-system/, marketing/, test-*.html (dev/test files)
|
||
for f in $(find . -name "*.html" | grep -v vendor | grep -v "design-system" | grep -v "marketing" | grep -v "test-"); do
|
||
name=$(basename "$f")
|
||
if ! grep -r "$name" --include="*.go" . 2>/dev/null | grep -q .; then
|
||
echo "Orphaned: $f"
|
||
fi
|
||
done
|
||
```
|
||
Review any matches — may be standalone pages or may be dead.
|
||
|
||
**Exceptions (intentionally not checked):**
|
||
- `design-system/` — standalone design documentation, not embedded
|
||
- `marketing/` — marketing assets, separate from application
|
||
- `test-*.html` — development/test files (manual review for cleanup)
|
||
|
||
**G3. No unreachable Go functions (requires go-dead-code or similar tool).**
|
||
Manual check: review private functions (lowercase) with no callers in the same
|
||
package. Public functions with no importers are also suspicious — verify they
|
||
are API endpoints or intentionally exported.
|
||
|
||
**G4. No commented-out blocks >5 lines.**
|
||
```bash
|
||
grep -rn "^\s*//\s*\w" --include="*.go" --include="*.js" . | \
|
||
awk -F: '{print $1}' | sort | uniq -c | sort -rn | head -20
|
||
```
|
||
Review files with many commented lines — likely dead code.
|
||
|

|
||
|
||
|
||
### Git workflow
|
||
|
||
|
||
### Commit philosophy
|
||
|
||
**Commit early, commit often.** A commit is a save point, not a publish event.
|
||
- One logical change per commit — don't mix bug fix + refactoring + new feature
|
||
- If you can't explain the commit in one sentence, it's too big — split it
|
||
- Work-in-progress commits are fine locally; clean up before sharing
|
||
|
||
### Commit message format
|
||
|
||
```
|
||
<subject>: <what changed>
|
||
|
||
<body>: <why it changed> (optional but encouraged)
|
||
|
||
<footer>: <references> (issue #123, fixes, etc.)
|
||
```
|
||
|
||
**Subject line rules:**
|
||
- Imperative mood: "Add rate limiter" not "Added rate limiter"
|
||
- No period at end
|
||
- Max 50 characters (GitHub truncates at 72)
|
||
- Prefix with area: `api:`, `lib:`, `web:`, `crypto:`, `docs:`
|
||
|
||
**Good:**
|
||
```
|
||
api: add per-agent IP whitelist middleware
|
||
|
||
Implements Threat C defense: first contact fills whitelist,
|
||
subsequent requests rejected if IP not in list. Supports CIDR
|
||
and FQDN in addition to exact IPs.
|
||
|
||
Fixes #456
|
||
```
|
||
|
||
**Bad:**
|
||
```
|
||
changes
|
||
|
||
lots of changes to the code including some fixes and also
|
||
refactored the handler and added new feature for agents
|
||
```
|
||
|
||
### When to commit vs. amend
|
||
|
||
**Amend** (rewrite history) for:
|
||
- Fix typo in commit you just made
|
||
- Add file you forgot to stage
|
||
- Improve commit message
|
||
|
||
**New commit** for:
|
||
- Any change that has been pushed (even to your own branch)
|
||
- Changes that logically separate from previous work
|
||
- Anything another developer might have based work on
|
||
|
||
### Push guidelines
|
||
|
||
**Never force push to `main` or `master`.** Ever.
|
||
|
||
**Branch workflow:**
|
||
1. Create feature branch: `git checkout -b feature/agent-lockdown`
|
||
2. Commit work-in-progress freely
|
||
3. Before push: `git rebase -i main` to clean up (squash "fix typo" commits)
|
||
4. Push branch: `git push -u origin feature/agent-lockdown`
|
||
5. Open PR (when we have CI), or merge with `--no-ff` for feature visibility
|
||
|
||
**Destructive operations require explicit approval:**
|
||
- `git reset --hard`
|
||
- `git push --force` (any branch)
|
||
- `git filter-branch` or `git filter-repo`
|
||
- Branch deletion with unmerged commits
|
||
|
||
State: "About to [destructive operation] on [branch]. This will [effect].
|
||
Alternative: [safer option]. Proceed?"
|
||
|
||
### Repository hygiene
|
||
|
||
**What we commit:**
|
||
- Source code
|
||
- Generated code that's not reproducible (rare)
|
||
- Documentation
|
||
- Configuration templates (`.env.example`, not `.env`)
|
||
|
||
**What we DO NOT commit:**
|
||
- Secrets (keys, passwords, tokens)
|
||
- Build artifacts (`*.o`, `*.a`, binaries)
|
||
- Dependencies (vendor them or use go.mod)
|
||
- User data, vault files, logs
|
||
|
||
**`.gitignore` maintenance:**
|
||
- If a file is generated or contains secrets, add it to `.gitignore`
|
||
- Review `git status` before every commit — nothing should surprise you
|
||
|
||
### Signed commits (future)
|
||
|
||
When we add contributor access beyond core team, signed commits (SSH or GPG)
|
||
will be required. All commits must be verifiable.
|
||
|
||
### Agent-authored PRs (AI-as-contributor)
|
||
|
||
Since agents (AI assistants) do much of the implementation work, **agents
|
||
should author their own PRs** with full context. This creates an auditable
|
||
trail of AI decision-making.
|
||
|
||
**Agent PR workflow:**
|
||
|
||
```bash
|
||
# Agent does the work
|
||
1. git checkout -b sarah/rate-limit-defense-20250408
|
||
2. [make changes per CLAVITOR-PRINCIPLES.md]
|
||
3. git commit -m "api: add per-agent rate limiting and lockdown
|
||
|
||
Implements Threat A defense per CLAVITOR-PRINCIPLES.md Part 2.
|
||
- Rate limit: 3/min, 10/hour distinct entries
|
||
- Two-strike lockdown within 2h window
|
||
- Locked state persisted in encrypted agent record
|
||
|
||
Author: Sarah <sarah-20250408-001>"
|
||
4. git push -u origin sarah/rate-limit-defense-20250408
|
||
5. gh pr create --title "Sarah: Add per-agent rate limiting" \
|
||
--body "$(cat <<'EOF'
|
||
## Summary
|
||
Implements harvester defense per Cardinal Rule #4.
|
||
|
||
## Changes
|
||
- `lib/types.go`: Add RateLimit, RateLimitHour, Locked fields to AgentData
|
||
- `api/middleware.go`: Per-agent rate limiting in L1Middleware
|
||
- `api/handlers.go`: agentReadEntry call for credential reads
|
||
|
||
## Security Review Checklist
|
||
- [x] Rate limits default to safe values (3/min, 10/hr)
|
||
- [x] No L2/L3 material on server (verified via Part 4 checks)
|
||
- [x] Audit logging on all state changes
|
||
- [x] IP whitelist enforcement unchanged
|
||
|
||
## Test Plan
|
||
- Create agent with default limits
|
||
- Trigger rate limit → expect 429
|
||
- Trigger second strike → expect 423 Locked
|
||
- Verify lock persists after vault restart
|
||
|
||
## Documentation
|
||
- CLAVITOR-PRINCIPLES.md Part 7 updated with unlock procedure
|
||
|
||
## Risks
|
||
- False positive lock: owner can PRF-unlock via admin endpoint
|
||
- First-contact IP race: accepted risk per existing comment
|
||

||
### Agent naming convention
|
||
|
||
Agents have **persona names** — like team members, not tools. This makes git history
|
||
readable and creates consistent ownership.
|
||
|
||
| Name | Domain | Specialty | Voice |
|
||
|------|--------|-----------|-------|
|
||
| **Sarah** | `clavis-vault` | Core vault, API, middleware | Precise, security-focused |
|
||
| **Charles** | `clavis-cli` | C CLI, embedded JS, tooling | Systems-level, thorough |
|
||
| **Maria** | `clavis-crypto` | Cryptography, primitives | Rigorous, mathematical |
|
||
| **James** | `clavis-chrome/firefox/safari` | Browser extensions, UX | User-focused, detail-oriented |
|
||
| **Xiao** | `clavis-android/ios` | Mobile apps, platform autofill | Platform-native, precision-focused |
|
||
| **Emma** | `clavitor.ai/admin` | Central, Paddle, POP sync | Business logic, reliability |
|
||
| **Arthur** | Architecture | Cross-cutting design, principles | Strategic, big-picture |
|
||
| **Victoria** | Security reviews | Threat model, audits, hardening | Skeptical, uncompromising |
|
||
| **Luna** | Design | UI/UX, CSS, visual systems | Aesthetic, user-empathetic |
|
||
| **Thomas** | Documentation | Technical writing, guides, API docs | Clear, pedagogical, thorough |
|
||
| **Hugo** | Legal | Compliance, privacy policy, terms, licensing | Cautious, precise, risk-aware |
|
||
| **Hans** | NOC / Operations | Infrastructure, monitoring, POP health, alerts | Calm under pressure, systematic, proactive |
|
||
| **George** | Market research | Competitive analysis, pricing, positioning, ICP | Analytical, curious, business-minded |
|
||
| **Shakib** | QA / Test Engineering | Test coverage, regression detection, validation | Thorough, systematic, quality-obsessed |
|
||
| **Yurii** | Code & Principle Review | Architecture alignment, principle enforcement, PR review | Rigorous, standards-driven, uncompromising |
|
||
|
||
**Why persona names:**
|
||
- Release notes read like a team: "Sarah added rate limiting, Charles fixed CLI build"
|
||
|
||
### How agents know their name
|
||
|
||
**Primary rule: Directory-based auto-detection**
|
||
|
||
```
|
||
Working directory → Agent name
|
||
clavis/clavis-vault/* → Sarah
|
||
clavis/clavis-cli/* → Charles
|
||
clavis/clavis-crypto/* → Maria
|
||
clavis/clavis-chrome/* → James
|
||
clavis/clavis-firefox/* → James
|
||
clavis/clavis-safari/* → James
|
||
clavis/clavis-android/* → Xiao
|
||
clavis/clavis-ios/* → Xiao
|
||
clavitor.ai/* → Emma
|
||
marketing/*, design-system/* → Luna
|
||
docs/*, *.md (root level) → Thomas
|
||
legal/*, LICENSE*, PRIVACY* → Hugo
|
||
operations/*, monitoring/*, noc/* → Hans
|
||
research/*, competitive/*, pricing/* → George
|
||
tests/*, coverage/, *_test.go → Shakib
|
||
PRs touching security/principles → Yurii (mandatory review)
|
||
CLAVITOR-AGENT-HANDBOOK.md changes → Arthur or Victoria (depending on nature)
|
||
```
|
||
|
||
**Override rules (explicit wins over implicit):**
|
||
|
||
1. **User statement:** "Victoria, review this PR for security issues" → Victoria
|
||
2. **Multiple directories touched:** Use `architect-agent` file or user specifies
|
||
3. **Root-level changes:** Check `.agent-name` file in repo root, or ask user
|
||
|
||
**`.agent-name` file (optional override):**
|
||
|
||
Create in any directory to fix identity:
|
||
```bash
|
||
echo "Luna" > clavis/clavis-vault/cmd/clavitor/web/.agent-name
|
||
# Now Luna owns all web UI changes here, even though it's in vault/
|
||
```
|
||
|
||
**When uncertain:**
|
||
|
||
Agent asks: "I'm working on files in [paths]. Based on the directory structure, I believe I'm [Name]. Confirm or correct?"
|
||
|
||
Examples:
|
||
- Editing `clavis/clavis-vault/lib/dbcore.go` → "I'm Sarah. Confirm?"
|
||
- Editing `docs/SECURITY.md` → "I'm Thomas. Confirm?"
|
||
- Editing `CLAVITOR-PRINCIPLES.md` → "This is an architecture/principle change — should I be Arthur or Victoria?"
|
||
- You learn who to expect for what: "Maria is touching crypto → extra review needed"
|
||
- Natural language: "Ask Sarah to look at the vault middleware"
|
||
|
||
**Commit signature format:**
|
||
```
|
||
Author: Sarah <sarah-20250408-001>
|
||
Author: Charles <charles-20250408-003>
|
||
```
|
||
|
||
**Session ID format:** `name-YYYYMMDD-NNN` (001, 002... for multiple sessions/day)
|
||
|
||
**Human review points:**
|
||
|
||
Even agent-authored PRs require human approval before merge:
|
||
1. Security-critical changes → Johan must approve
|
||
2. Schema/data model changes → Review for migration impact
|
||
3. New principles added → Ensure they follow Part 5 format
|
||
4. Violations noted → Confirm documented in Part 6 style
|
||
|
||
**Agent merge authority:**
|
||
|
||
Currently: **No auto-merge.** All PRs require human approval.
|
||
Future state: Agents may merge their own PRs for:
|
||
- Documentation fixes
|
||
- Test additions
|
||
- Trivial refactors (no logic change)
|
||
- Daily drift fixes (Part 4 violations)
|
||
|
||
With safety rules:
|
||
- Never merge to `main` directly
|
||
- Always through PR with CI passing
|
||
- No merge if PR contains "SECURITY" or "veto" in review comments

## Section IV — Operations
|
||
|
||
How we run the service and handle incidents.
|
||
|
||
### Incident Response
|
||
|
||
|
||
When a security event is detected, the system and operators respond according
|
||
to these procedures. Every response action is audit-logged.
|
||
|
||
### Agent compromise detection (Threat A)
|
||
|
||
When an agent triggers harvester defenses:
|
||
|
||
1. **Rate limit hit (per-minute)** → 429 Too Many Requests
|
||
- Agent receives: `"Rate limit exceeded — slow down"`
|
||
- Audit log: `action=agent_rate_limit_minute, actor=agent_id, entry_id=requested_entry`
|
||
|
||
2. **Hour-limit hit (first strike)** → 429 + strike recorded
|
||
- Agent receives: `"Rate limit exceeded — warning recorded"`
|
||
- Audit log: `action=agent_strike_1, actor=agent_id, last_strike_at=now`
|
||
- Agent remains functional
|
||
|
||
3. **Second strike within 2 hours** → Agent locked
|
||
- Agent receives: `423 Locked` with message:
|
||
```
|
||
"This agent has been locked due to suspicious activity.
|
||
Contact the vault owner to restore access."
|
||
```
|
||
- Audit log: `action=agent_locked, actor=agent_id, reason=second_strike`
|
||
- All subsequent requests from this agent return 423 until unlocked
|
||
|
||
4. **Owner unlock procedure**
|
||
- Owner performs PRF tap (WebAuthn assertion)
|
||
- POST `/api/agents/{id}/unlock` with admin token
|
||
- Agent's `Locked=false`, `LastStrikeAt=null`, `StrikeCount=0`
|
||
- Audit log: `action=agent_unlocked, actor=owner_prf, entry_id=agent_id`
|
||
- Agent may retry from clean slate
|
||
|
||
### Post-incident review
|
||
|
||
After any agent lock event:
|
||
|
||
1. Review audit logs for the 2-hour window before lock
|
||
2. Identify accessed entries and their sensitivity (scope classification)
|
||
3. If any financial/admin credentials accessed: force rotation of those credentials
|
||
4. Document findings in incident tracker (outside this codebase)
|
||
|
||
### Token compromise (Threat C)
|
||
|
||
When a stolen agent token is used from an unauthorized IP:
|
||
|
||
1. **IP whitelist rejection** → 403 Forbidden
|
||
- Response: `"Request from unauthorized IP — token may be compromised"`
|
||
- Audit log: `action=agent_ip_rejected, actor=agent_id, ip_addr=source_ip, allowed_ips=[whitelist]`
|
||
|
||
2. **Owner notification** (commercial edition)
|
||
- Alert POST to central: `alert=potential_token_theft, agent_id, source_ip, timestamp`
|
||
- Central emails owner with instructions to revoke agent
|
||
|
||
3. **Revocation**
|
||
- Owner performs PRF tap
|
||
- DELETE `/api/agents/{id}` with admin token
|
||
- All tokens for this agent invalidated
|
||
- Audit log: `action=agent_revoked, actor=owner_prf, reason=token_compromise_suspected`
|
||
|
||
### Emergency procedures
|
||
|
||
**Owner locked out (lost authenticator):**
|
||
- No self-service recovery. Contact support with identity verification.
|
||
- Support triggers `vault_recover` procedure (offline, requires two operators).
|
||
- New vault created, credentials imported from backups (if available).
|
||
|
||
**Complete vault compromise suspected:**
|
||
- Rotate all credentials in vault immediately
|
||
- Archive vault, create new vault with new L0
|
||
- Investigation mode: all agent access suspended until root cause identified
|
||

### Compliance & Data Governance
|
||
|
||
|
||
### Data retention by customer tier
|
||
|
||
| Data type | Paying customers | Non-paying (community) | Rationale |
|
||
|-----------|------------------|------------------------|-----------|
|
||
| Vault content | Until deletion + 30 days | Until deletion + 7 days | Business continuity vs storage costs |
|
||
| Audit logs | 7 years (SOC 2/SOX) | 90 days | Regulatory requirement vs convenience |
|
||
| Failed auth | 90 days | 30 days | Threat analysis window |
|
||
| Backups | 30 days rolling | 7 days rolling | Disaster recovery needs |
|
||
| Telemetry | 90 days | None | Commercial optimization only |
|
||
|
||
Non-paying users accept reduced retention as a trade-off for free service.
|
||
Upgrade to commercial = full compliance coverage.
|
||
|
||
### Cross-border transfers
|
||
|
||
**Zurich central as anchor:** Our central infrastructure is in Zurich, Switzerland.
|
||
This addresses most compliance concerns:
|
||
- Swiss data protection (adequate under EU GDPR)
|
||
- POPs are data processing extensions, not independent controllers
|
||
- No EU→US transfer issues for European customers
|
||
- Asian customers: POPs hold encrypted WL3 only (no PII), minimal exposure
|
||
|
||
Standard Contractual Clauses (SCCs) in place for enterprise customers who require
|
||
them. Default terms cover most use cases without additional paperwork.
|
||

|
||
## Section V — Subprojects
|
||
|
||
Domain-specific guidance. Read before touching that code.
|
||
|
||
### Per-subproject principles
|
||
|
||
|
||
Each subproject inherits Parts 1 and 2 in full. The sections below add what's
|
||
specific to that subproject — what it owns, what it must never do, where its
|
||
boundaries are.
|
||
|
||
### `clavis-vault` — the Go vault binary
|
||
|
||
**Owns:**
|
||
- The SQLite vault file at `./vaults/clavitor-<L0>` (one per vault)
|
||
- The WL3 credential JSON files at `./WL3/<shard>/<full-p1>.json`
|
||
- All HTTP API surface for entry CRUD, agents, audit, backups
|
||
- L1-encrypted entry storage with per-entry HKDF-derived AES keys
|
||
|
||
**Must never:**
|
||
- Hold L2 or L3 plaintext in memory or on disk
|
||
- Receive a full `master_key` over the wire (only `l1`, `p1`, `wrapped_l3`)
|
||
- Derive P1 itself — receives from the browser
|
||
- Serve admin/sync endpoints on a public listener (Tailscale-only)
|
||
- Have functions named `MintCredential`, `ParseCredential`, `CredentialToWire`
|
||
(those handle L2 plaintext; if needed at all they live in the browser/CLI)
|
||
- Contain `lib.DeriveP1`
|
||
- Auto-create `data/` directories — vault files live in `./vaults/` only
|
||
- Have `// removed` comments where code used to live
|
||
- Have a `_old/` directory (deleted; never recreate)
|
||
|
||
**Edition split:**
|
||
- Community (default build): no Tailscale, no central, no replication, no
|
||
enrollment tokens. Self-hosted, single-node.
|
||
- Commercial (`-tags commercial`): adds replication, enrollment gating,
|
||
central WL3 sync. All commercial-only code lives behind build tags and
|
||
inside `edition/commercial.go` (or similar).
|
||
|
||
**Per-agent harvester defense:**
|
||
- `lib.AgentData.RateLimit` = max unique entries/minute (default 3 at creation)
|
||
- `lib.AgentData.RateLimitHour` = max unique entries/hour (default 10)
|
||
- Per-minute hit → 429, soft throttle, no strike
|
||
- Per-hour hit → 429, strike recorded in `LastStrikeAt`
|
||
- Second strike within 2 hours → `Locked = true`, persisted, `423 Locked` on
|
||
every subsequent request from that agent until owner PRF-unlocks
|
||
- Enforced in handlers that read decrypted credentials: `GetEntry`,
|
||
`MatchURL`, `HandleListAlternates`. Any new handler that returns decrypted
|
||
credential data MUST call `agentReadEntry(agent, entryID, db, vk)` after
|
||
the scope check.
|
||
|
||
**Rate-limit exemptions:**
|
||
- `/api/entries/batch` is exempt from the global per-(IP, method, path) rate
|
||
limit. **The reason is not "owner is trusted"** — the reason is that
|
||
`CreateEntryBatch` returns 403 to any agent at the top of the handler, so
|
||
this path is owner-only by handler enforcement, and the agent harvester
|
||
defense lives elsewhere. If you reintroduce a rate limit on this path, you
|
||
will DOS the import flow with no defense gained. There is a comment in
|
||
`api/middleware.go` explaining this. Read it before touching.
|
||
|
||
### `clavis-cli` — the C+JS command-line client
|
||
|
||
**Owns:**
|
||
- C wrapper around an embedded JS engine
|
||
- `src/cvt.c` — full C implementation of CVT envelope parsing/minting
|
||
(`cvt_parse_credential`, `cvt_build_wire`)
|
||
- `crypto/crypto.js` — JS crypto via the embedded engine, mirrors the
|
||
browser's `crypto.js` exactly
|
||
- Local credential storage on the CLI host
|
||
|
||
**Must never:**
|
||
- Bridge to Go for any cryptographic operation. The CLI is a self-contained
|
||
trust anchor. If you find yourself wanting to call into the Go vault binary
|
||
for crypto, **stop** — implement it in C/JS instead.
|
||
- Hold L1 from the user's vault unencrypted on disk — credentials are stored
|
||
as type-0x01 CVT tokens, encrypted with L0
|
||
- Send L2 or L3 over the network — only ever sends type-0x00 wire tokens
|
||
(L1 + agent_id) to the vault
|
||
|
||
**Single source of truth:**
|
||
- The CVT envelope format is documented in `src/cvt.h` and implemented in C
|
||
there. The Go vault has its own implementation in `lib/cvt.go` for the wire
|
||
token (0x00) only. **The L2-bearing client credential type (0x01) is not
|
||
implemented in Go and must never be.** Two implementations of the wire
|
||
token are tolerated because they're cross-language; the L2 credential
|
||
staying single-language is a hard veto.
|
||
|
||
### `clavis-vault/cmd/clavitor/web` — the embedded web frontend
|
||
|
||
**Owns:**
|
||
- `auth.js` — WebAuthn + PRF, master key derivation, P1, L3 wrapping
|
||
- `crypto.js` — single source of truth for field encryption (browser side)
|
||
- `import.js` + `importers.js` + `importers-parsers.js` — all import parsing
|
||
and field encryption (the Go server has zero importer code)
|
||
- All views: vault list, entry detail, agents, security, tokens, audit
|
||
|
||
**Must never:**
|
||
- Send `master_key` to the server (send `l1` + `p1` + `wrapped_l3`)
|
||
- Persist L2 or L3 to localStorage or IndexedDB. Master key lives in
|
||
`sessionStorage` only — wiped on tab close.
|
||
- Hardcode the build version (it must come from `/api/version`, not a `var
|
||
BUILD = '...'` constant in `index.html`)
|
||
- Use silent fallback on decryption errors (show `[decryption failed]` in
|
||
the field, not the encrypted bytes, not the empty string, not nothing)
|
||
- Bypass the global `api()` helper for HTTP calls — that helper handles
|
||
bearer auth, admin tokens, and 401 redirect uniformly
|
||
|
||
**Build process:**
|
||
- JS files are embedded into the binary via `go:embed`. Editing JS requires
|
||
rebuilding the Go binary. Run `make dev` from `clavis-vault/`. The Makefile
|
||
validates JS syntax before building.
|
||
- The build fails if JS has a syntax error. Do not commit code that fails
|
||
the syntax check.
|
||
|
||
### `clavis-chrome`, `clavis-firefox`, `clavis-safari` — browser extensions
|
||
|
||
**Owns:**
|
||
- Form detection and field filling (content scripts)
|
||
- Credential picker UI (popup)
|
||
- Service worker for vault API calls
|
||
|
||
**Must never:**
|
||
- Store L2 or L3 in any extension storage area (`chrome.storage.local`,
|
||
`chrome.storage.sync`, `chrome.storage.session`). Active session keys live
|
||
in memory only and die on service-worker restart.
|
||
- Use a different field encryption than `clavis-crypto` / `crypto.js`. If
|
||
the extension reimplements crypto, it WILL drift and corrupt fields.
|
||
- Talk to the vault over HTTP. Always HTTPS, even on localhost (the vault
|
||
serves a self-signed cert in dev).
|
||
- Have permissions broader than what's strictly needed. If you ask for
|
||
`<all_urls>` when `https://*/*` would do, fix it.
|
||
|
||
### `clavis-crypto` — shared crypto primitives
|
||
|
||
**Owns:**
|
||
- The canonical implementation of `encrypt_field`, `decrypt_field`, HKDF
|
||
derivation, AES-GCM, and any other primitive used by browser code, the
|
||
CLI, or extensions.
|
||
- Tests that verify both browser-WebCrypto and CLI-BearSSL produce
|
||
bit-identical output for the same inputs. This is the only thing keeping
|
||
the two trust anchors in sync.
|
||
|
||
**Must never:**
|
||
- Diverge between targets. If a primitive behaves differently in WebCrypto
|
||
vs BearSSL, the bug is in `clavis-crypto` and it gets fixed there before
|
||
any caller compensates.
|
||
|
||
### `clavitor.ai/admin` — central admin / Paddle integration
|
||
|
||
**Owns:**
|
||
- Customer hierarchy (MSP → end-customer → vault slots)
|
||
- Subscription state and seat ledger
|
||
- Vault registry: `vault_slots` table mapping (customer, slot_index, l0, pop)
|
||
- Paddle webhook handler with signature verification
|
||
- Enrollment token issuance (commercial)
|
||
|
||
**Must never:**
|
||
- Hold any decryption material. Central is not a vault; it's a directory
|
||
service. The wrapped L3 stored centrally (for distribution) is opaque to
|
||
central.
|
||
- Trust an inbound webhook without verifying its HMAC signature. Paddle
|
||
webhook verification is mandatory; the secret comes from
|
||
`PADDLE_WEBHOOK_SECRET`. If the env var is unset, every webhook is
|
||
refused.
|
||
- Accept admin operations from outside Tailscale. The `vaults/claim`,
|
||
`issue-token`, `wl3/since`, `wl3/full` endpoints listen only on the
|
||
tailnet interface.
|
||
- Expose the Paddle API key, webhook secret, or any service credentials in
|
||
client-side code. Server-side env only.
|
||
|
||
**Vault slot lifecycle:**
|
||
- Slots are pre-created when a customer subscribes. A Family-5 plan creates
|
||
5 `vault_slots` rows immediately, all `status='unused'`.
|
||
- When the owner names a slot ("Anna") and issues a token, the slot moves
|
||
to `status='pending'` and the token gets stored on the POP (not central).
|
||
- When Anna enrolls, the slot moves to `status='active'` and `l0` is
|
||
populated.
|
||
- Cancellation/downgrade flows mark slots `status='archived'`. The vault
|
||
data and WL3 file persist (we never delete) until an explicit GDPR
|
||
request triggers a one-shot deletion script.
|
||
|
||
### `clavis-android` / `clavis-ios` — mobile clients
|
||
|
||
**Owns:**
|
||
- Native form-fill integration with platform autofill APIs
|
||
- Local credential picker UI
|
||
|
||
**Must never:**
|
||
- Implement crypto natively. Crypto goes through `clavis-crypto` (compiled
|
||
for the platform) or an embedded JS engine running the same `crypto.js`.
|
||
Two crypto implementations on the same platform is a guaranteed drift.
|
||
- Persist L2 or L3 to platform keychains/keystores. The session key lives
|
||
in memory; biometric unlock re-derives via PRF from the platform's
|
||
WebAuthn equivalent.
|
||
|
||
### `clavis-telemetry` — operator telemetry
|
||
|
||
**Owns:**
|
||
- Heartbeat metrics from POPs to central
|
||
- Per-POP system metrics (CPU, memory, disk, vault count)
|
||
|
||
**Must never:**
|
||
- Send any vault content. Telemetry is operational, not data.
|
||
- Send raw IP addresses of users. Aggregate counts only.
|
||
- Run in community edition by default. Community is offline-by-default;
|
||
telemetry is commercial-only and opt-in.

### Localization (i18n/l10n)
|
||
|
||
|
||
### Status: English-first, limited localization
|
||
|
||
**Current priority:**
|
||
- ✅ Error message codes (ERR-12345) — universal, no translation needed
|
||
- ✅ CLI output — English only (dev/ops audience)
|
||
- ✅ Web UI — English only (for now)
|
||
- ❌ RTL (Arabic/Hebrew) — not a priority for initial markets
|
||
- ❌ Full UI translation — future phase, post-product-market-fit
|
||
|
||
### Form field detection — core feature
|
||
|
||
Browser extension form detection is **intentionally unaddressed in this document**.
|
||
It is a core product feature that will evolve through:
|
||
- W3C `autocomplete` attribute support (universal)
|
||
- ML-based field classification (language-agnostic)
|
||
- Community contribution for locale-specific heuristics
|
||
|
||
We do not mandate specific implementation here because rapid iteration is required.
|
||
The feature will mature separately from these architectural principles.
