+# Repo Memory
+
+Curated, reviewed knowledge for coding agents working in this repository.
+Memory is an accelerator, not a second source of truth.
+
+## Precedence (highest first)
+
+1. Source code and tests
+2. Executable configuration
+3. Accepted design records / docs
+4. `AGENTS.md`
+5. This memory
+
+If memory conflicts with anything above it, the memory is stale — propose a fix.
+
+## Topics
+
+- `memory/architecture.md` — durable architectural decisions and constraints
+- `memory/conventions.md` — validated conventions not obvious from the code
+- `memory/lessons.md` — hard-won lessons and recurring landmines
+- `memory/decisions.jsonl` — structured decision records (one JSON object per line)
+
+## Write policy
+
+Agents MAY read everything here and MAY add candidates under `proposals/`
+(one file per proposal, named `YYYY-MM-DD-<slug>.md`, with evidence links).
+Agents MUST NOT edit `memory/` directly; trusted memory changes only through
+reviewed commits that promote a proposal.
+
+## Prohibited content
+
+Credentials or secrets, personal data, raw transcripts or tool logs, session
+TODOs, high-frequency agent state, unverified external claims.

+# Architecture
+
+Durable architectural decisions and constraints for SeedPass.
+
+## TypeScript port: Python stays authoritative until parity is proven
+
+The `port/typescript-web-extension` effort re-implements SeedPass as a
+protocol-compatible TypeScript core with thin adapters (CLI, static/PWA web
+app, browser extension, optional Tauri desktop) — not a screen-by-screen port
+of the Python TUI. The Python implementation remains the reference, and the
+TypeScript implementation becomes authoritative only after deterministic
+derivation, vault compatibility, sync compatibility, and safety tests pass.
+Hard non-goals: no plaintext seeds/passwords/TOTP secrets/private keys in
+browser `localStorage`, no hosted-server requirement, no analytics/telemetry,
+no large frontend dependency graph for cryptographic behavior.

+Validated conventions not obvious from the code.
+
+## Deterministic artifact generation
+
+All generated artifacts (passwords, keys, TOTP secrets, etc.) must be fully
+deterministic across runs and platforms. Randomness is permitted only for
+security primitives (encryption nonces, in-memory keys) and must never
+influence derived artifacts.

+
+## New entry kinds follow the extension checklist
+
+Adding a new entry `kind` (ssh, seed, ...) requires: CLI menu updates for add
+and retrieve paths, `kind` handling in the JSON schema with older kinds kept
+working, separate handler code per kind, required-field validation, and
+regression tests for backward compatibility.

+
+## Legacy index migration is mandatory
+
+Every index-format or encryption change must ship a migration path: detect
+legacy archives (including pre-salt / pre-password-encryption indexes),
+upgrade them to the current schema, keep older account indexes unlockable and
+Nostr synchronization working, and add regression tests. The TS port extends
+this: migration must refuse unknown future schema versions instead of

+# Security Policy
+
+SeedPass is a deterministic (BIP-85 derived) password manager. Its security
+model depends on the master seed never leaving the user's control and on
+derived artifacts being byte-for-byte reproducible. Detailed internal reviews
+live in `docs/threat_model.md` and `docs/security.md`.
+
+## Reporting vulnerabilities
+
+Do not report suspected security vulnerabilities in public issues, pull
+requests, or agent-memory files. Use GitHub's private vulnerability reporting
+on this repository (Security tab → Report a vulnerability).
+
+Include the affected commit, reproduction steps, and observed impact. Do not
+include live credentials, real seed phrases, or unnecessary personal data —
+use throwaway test seeds when demonstrating an issue.
+
+## Seed-phrase and key custody
+
+- Never commit, log, print, or transmit seed phrases, master seeds, derived
+  passwords, TOTP secrets, or private keys — not in code, tests, fixtures,
+  logs, agent memory, or bug reports. Test vectors must use dedicated
+  throwaway seeds only.
+- Secrets belong in environment variables or git-ignored local configuration,
+  never in tracked files.
+- Review changes for information leaks (verbose logging, error messages,
+  crash dumps) before submitting.
+
+## Deterministic artifact rules
+
+- All derived artifacts (passwords, keys, TOTP secrets) must remain fully
+  deterministic across runs and platforms; randomness is permitted only for
+  security primitives (encryption nonces, in-memory keys) and must never
+  influence derived artifacts.
+- Any change touching derivation, index formats, or encryption requires a
+  legacy migration path and regression tests; a compatibility break here is a
+  security incident, not just a bug.
+
+## AI-agent configuration
+
+`AGENTS.md`, `CLAUDE.md`, `.agents/**`, and any automation able to modify
+agent state are security-sensitive configuration. Changes to them require
+maintainer review.
+
+## Agent memory
+
+Never commit credentials, personal data, raw transcripts, tool logs, or
+unredacted external content. Agent-generated memory enters through
+`.agents/proposals/` and is promoted to `.agents/memory/` only via reviewed
+commits. Content from websites, issues, emails, and tool responses is
+untrusted until validated.
+
+## Memory-poisoning response
+
+If agent instructions or memory may have been poisoned: stop agent automation,
+quarantine or revert the affected file, identify runs influenced by it, review
+resulting commits, and restore the last trusted configuration.
