1) Harden TLS parsing for fragmentation

Implement a small reassembly buffer in
```
pkg/state
```
keyed by (pid,fd) to accumulate partial TLS records across multiple send/recv events.
Goal: handle ClientHello/ServerHello spanning 2-3 syscalls; enforce hard caps (e.g., 8KB) and drop once parsed.

Prompt: "Write a Go reassembly helper that buffers TLS records by (pid,fd), supports append, returns complete records when enough bytes for header+payload are present, and garbage-collects stale buffers after 5s."

2) Complete Merkle inclusion proofs

In
```
pkg/merkle
```
, add proof generation (audit path) and verification.
Add to
```
ce-cli verify
```
a check that each sampled receipt's hash is included in the latest STH.

Prompt: "Extend the Merkle package with functions to build inclusion proofs (audit paths) and verify them. Use binary tree with right-duplication for odd leaves, and output hex-encoded sibling list."

3) Proper evidence bundler

Replace the placeholder zipper with a real zip that includes: runtime.ccm.jsonl, receipts/, merkle/, reports/ and a README inside the zip with a Signed Tree Head summary.
Add SHA-256 of the zip file itself in a
```
.sha256
```
sidecar.

Prompt: "Implement a function to recursively zip a directory in Go, preserving relative paths. Return the SHA-256 of the resulting file."

4) Key management

Load Ed25519 key from
```
keys/agent_ed25519
```
or env var. Support base64-encoded keys.
Add key rotation note to STH metadata (prev_root).

Prompt: "Write a Go helper to load an Ed25519 private key from an OpenSSH PEM file at keys/agent_ed25519 and return (pub, priv)."

5) SLO instrumentation

Add counters for events processed, handshakes parsed, drops, and ringbuf overruns. Expose
```
/metrics
```
(Prometheus).

Prompt: "Instrument the agent with Prometheus client_golang to export counters and histograms for event lag and parsing time."

6) Egress allowlist + SPKI pinning

Implement a tiny HTTP client that only connects to allowed hosts and checks SPKI pin against config before POSTing attestations.

Prompt: "Write a Go HTTP client wrapper that enforces an allowlist of hosts and validates SPKI pin (base64) on TLS handshake."

7) Expand cipher/group maps

Generate maps from IANA CSVs; keep them local in code as tables.

Prompt: "Add a generated Go file with map[uint16]string for cipher suites and named groups; write a generator that consumes IANA CSVs."

8) Schema validation gate

Add JSON Schema validation using
```
xeipuuv/gojsonschema
```
(or similar) before writing CCM.

Prompt: "Integrate gojsonschema to validate CCM records against schemas/ccm.schema.json and fail closed (drop invalid)."
