## [v0.9.0] - 2026-07-01

v0.9.0 extends secret execution and adds a template engine for generating configuration files from vault secrets.

### Added

- **`symvault run --env-file`** — load multiple secret-to-environment mappings from a file, one `NAME=path.field` per line, with comment and blank-line support (#594).
- **`symvault run --passthrough`** — pass through selected parent environment variables to the child process, so variables such as `NODE_ENV` and `PORT` stay available (#594).
- **`symvault template generate`** — generate `.env`, Docker Compose, Kubernetes Secret, GitHub Actions, and Terraform files from vault secrets (#594).
- **Positional `KEY=ref` template arguments** — map arbitrary template keys to specific vault refs on the command line (#594).
- **`symvault template generate --prefix`** — auto-select every entry under a vault path prefix (for example, `work/`) and include each field as a template variable (#594).

### Fixed

- **Stdin forwarding in `symvault run`** — child processes now receive stdin, enabling heredocs and piped input (#594).


### Security

- macOS release binaries are now signed with a Developer ID and notarized by Apple, eliminating Gatekeeper warnings (#583)

### Changed

- Rename title to Symaira Vault (symvault) with former name note (#582)
- Quarterly re-audit of golang/protobuf migration documentation (#585)

## [v0.8.0] - 2026-06-25

### Added

- Type detection: infer secret type from path and field names (#567)
- TUI: sort entries by type with grouped headers (#567)
- Backup codes: structured data model and migration (#567)

### Fixed

- stdin-value: accept values without trailing newline (#566)
- Git push: use system git for SSH remotes (#566)
- Generated-password field storage: force SecretTypePassword with --generate (#568)
- Goroutine leak in ReencryptAll on early error (#579)

## [v0.7.1] - 2026-06-23

Security hardening, KDF improvements, search-index persistence, and bug
fixes since v0.7.0.

### Security

- **Argon2id zero-key self-heal** — automatically replaces a corrupted
  zero-length Argon2id key derived from `identity.age`, preventing silent
  decryption failures on restored or migrated vaults. KDF state is now
  derived from `identity.age` instead of recomputing on every unlock
  (#516).
- **Harden policy storage and MCP policy loading** — search isolation
  improvements and a resolved gosec gate ensure that policy files and
  MCP-loaded policies cannot be tampered with at rest or in transit
  (#524).
- **Cursor path sanitizer** — escape backslashes first in the cursor
  path sanitizer to prevent path-traversal bypasses via backslash
  sequences (#527).
- **Weak-sensitive-data-hashing** — fix `go/weak-sensitive-data-hashing`
  finding in `internal/vault/search_index.go` by replacing the weak hash
  with a safe alternative (#543, #540).
- **G304 false positive annotation** — annotate a known false positive
  in the KDF doctor check where the file path is user-controlled but
  validated before use (#518).

### Added

- **Search-index persistence** — the search index is now persisted to
  disk and restored on server startup, eliminating a cold-start re-scan
  of the full vault on every `serve` invocation (#532).
- **Manifest rebuild** — a new manifest-rebuild path ensures the vault
  manifest stays consistent after entry create, update, or delete
  operations (#516).
- **Projects v2 board** — a new GitHub Projects v2 board named `Symaira
  Vault` (number 11) is linked to this repository. The board includes a
  `Status` single-select (Todo / In Progress / Done), a `Priority`
  single-select (Urgent / High / Medium / Low), and an `Iteration` field
  with two-week iterations starting `2026-06-16` (v0.7.x, v0.8.x, v0.9.x,
  v0.10.x). The previous Projects v2 board (`symaira-vault`, number 1)
  remains read-only historical context. Tracked issues can now be
  assigned to an iteration alongside the milestone. See #508.

### Fixed

- **Recipients remove no longer revokes access** — removing a recipient
  from the vault no longer invalidates access to entries that were
  already encrypted for that recipient (#537).
- **Password strength by rune count** — measure password strength by
  rune count instead of byte length so multi-byte characters (CJK,
  emoji, accented letters) are counted correctly (#526).

### Changed

- **Search-index refactor** — the search index internals were refactored
  for clarity and the Argon2id KDF path was hardened against edge cases;
  build artifacts were cleaned up (#543).
- **Server-bootstrap cleanup** — the MCP server bootstrap sequence was
  simplified to reduce startup latency and remove dead code (#532).

### CI

- **Pin `docker/*` GitHub Actions** — pin `docker/build-push-action` and
  `docker/login-action` to SHA-pinned versions and fix an invalid
  `github-script` pin to prevent supply-chain drift (#511).

## [v4.0.0] - 2026-05-21

v4.0 reshapes Symaira Vault around AI-agent integration. The CLI becomes a
first-class surface for agents (dual to MCP), agent profiles gain an explicit
tier system, skill packages ship inside the binary, and the MCP server defaults
to a lean 7-tool surface to reduce context-window pollution.

See [docs/migration-v3-to-v4.md](docs/migration-v3-to-v4.md) for the upgrade
guide and [docs/skills/symaira-agent/UPGRADE-TO-V4.md](docs/skills/symaira-agent/UPGRADE-TO-V4.md)
for an AI-agent-ready upgrade prompt. Run `symvault migrate v4 --dry-run` to
preview, then `symvault migrate v4` to apply.

### Breaking changes

- **CLI consolidation.** All AI-integration commands moved under
  `symvault agent`. Replaced: `symvault mcp install`, `symvault mcp-config`,
  `symvault mcp token …`, `symvault mcp-token-rotate`, `symvault agent setup`.
  Deprecation stubs remain in v4.0 (print replacement, exit 2) and will be
  removed in v4.1.
- **MCP tool `openpass_delete` removed** (was an alias for `delete_entry` since
  v2.x). Callers receive `ERR_TOOL_NOT_FOUND`. Use `delete_entry`.
- **Default tier for `symvault agent install` is `safe`** (metadata-only).
  Upgrade explicitly with `symvault agent upgrade <name> --tier standard`.
- **Token `tools: ["*"]` now means "inherit from profile"** instead of "all
  tools the server knows." Profile changes take effect on the next call.
- **MCP `tools/list` lean mode by default** — returns 7 essential tools at
  connect time. Pass `include_all_tools: true` in init or call `openpass_search`
  for the full surface.

### Added — agent integration

- **`symvault agent install <name>`** — single command for agent setup:
  generates scoped token + writes MCP config + drops embedded skill package +
  runs smoke test. Flags: `--auto-detect`, `--tier`, `--http`, `--dry-run`,
  `--skill-only`, `--config-only`, `--force`, `--output json|yaml|text`.
- **`symvault agent upgrade <name> --tier <tier>`** — explicit, audited tier
  change with interactive diff. Non-interactive `--yes --reason "…"` requires a
  reason for the audit trail. Optional `--rotate-token`.
- **`symvault agent uninstall <name>`** — removes profile, token, skill, and
  MCP config entry; skill files without the Symaira Vault sentinel are preserved.
- **`symvault agent doctor <name>` / `--all`** — end-to-end diagnostic for one
  or all agent integrations; detects skill drift via hash comparison.
- **`symvault agent list`** — installed agents with tier, token status, last-seen.
- **`symvault agent token <name> new|list|revoke|rotate`** — token management
  per agent.
- **`symvault agent audit <name>` / `audit self`** — per-agent audit log with
  `--since` and `--format table|json`.
- **`symvault agent profile show|edit|export <name>`** — agent profile
  inspection and editing in `$EDITOR` with schema validation + confirmation.
- **`symvault agent skill export|refresh <agent>`** — pack skill for org
  distribution or re-render in place.
- **`symvault agent whoami --output json`** — CLI form of the `openpass_whoami`
  MCP tool.
- **`symvault agent prompt <path>.<field>`** — CLI form of `secure_input`.
- **`symvault agent request <path>.<field> --reason "…"`** — CLI form of
  `request_credential`.

### Added — MCP tools

- **`openpass_whoami`** — agent self-introspection: tier, allowed paths,
  quotas, available tools, vault status, CLI-alternative hint. Available in
  every tier; agents should call once per session.
- **`openpass_audit_self`** — agents read their own recent audit events
  (success, denied, redacted). Other agents' trails are not exposed.
- **`openpass_search`** — discover and on-demand-load tools by intent string.
  Returns matching tool spec inline plus `cli_alternative` for each match.
- **Lean-mode `tools/list`** — 7-tool default surface (`openpass_whoami`,
  `openpass_search`, `health`, `find_entries`, `get_entry_metadata`,
  `request_credential`, `openpass_audit_self`); ~83% less initial context.
- **Structured error responses** — every MCP error now returns
  `{ code, message, hint, details, doc }` with codes from
  `internal/mcp/errors/codes.go` (`ERR_PATH_FORBIDDEN`, `ERR_TOOL_NOT_ALLOWED`,
  `ERR_APPROVAL_DENIED`, `ERR_QUOTA_EXCEEDED`, …).
- **Tool descriptions for LLMs** — every tool documented in
  `internal/mcp/tooldocs/<tool>.md` with `USE WHEN`, `DON'T USE WHEN`, `INPUT`,
  `OUTPUT`, `COMBINES WELL WITH`, `EXAMPLE` sections.
- **`find_entries` returns mini-metadata inline** — `path`, `name`, `updated`,
  `version`, `score` per hit; saves repeat `get_entry_metadata` round-trips.

### Added — tier system

- **Three tier presets** in `internal/config/presets.go`: `safe` (alias for
  `read-only`), `standard`, `admin`. Each is snapshot-tested to prevent silent
  drift.
- **`safe` (default)** — metadata-only tools, no writes, no clipboard/autotype,
  no commands, deny-mode approvals, strict redaction.
- **`standard`** — adds value-read, write, clipboard, autotype, prompts; uses
  `prompt`-mode approvals for destructive ops.
- **`admin`** — adds command execution, profile management, exposes
  value-returning tools; prompts only on destructive ops.
- **Audit events** for tier lifecycle: `AGENT_INSTALLED`, `AGENT_TIER_CHANGED`,
  `AGENT_TIER_CHANGE_DENIED`, `AGENT_TOKEN_ROTATED`, `AGENT_UNINSTALLED`,
  `AGENT_QUOTA_HIT`.

### Added — skill packages

- **Per-agent skills embedded in the binary** via `internal/agentskill/assets/`
  with templates for `hermes`, `claude-code`, `codex`, `opencode`, `openclaw`,
  plus a `common/` base.
- **Sentinel-based lifecycle** — frontmatter `managed_by: symvault` +
  SHA-256 hash. Install/refresh/uninstall only touch files with the sentinel;
  user-edited skills are preserved unless `--force` is passed.
- **Deterministic rendering** — golden-file tests in
  `internal/agentskill/testdata/` enforce byte-identical re-renders.
- **Per-agent paths** resolved automatically (`~/.claude/`, `~/.codex/`,
  `~/.config/opencode/`, `~/.hermes/`, `~/.openclaw/`).

### Added — CLI as agent surface

- **`OPENPASS_AGENT=<name>` environment variable** applies the agent profile
  (allowed paths, redaction, quotas, audit) to every CLI call. Same enforcement
  logic as MCP.
- **`internal/agentctx/`** — shared profile-context loader used by both CLI
  and MCP dispatch paths; eliminates duplicate enforcement code.
- **`internal/quotas/`** — file-lock-based shared quota counter between CLI
  and MCP; both paths increment the same `~/.openpass/state/quotas/<agent>.json`.
- **Standardized exit codes** on every command:
  0/1/2/10/11/12/13/14/15.
- **`--output text|json|yaml`** on every command; JSON output is the contract
  for agent-driven CLI calls.

### Added — migration

- **`symvault migrate v4 [--dry-run] [--yes]`** — classifies existing v3
  profiles into tiers, computes skill drift, backs up `config.yaml` to
  `config.yaml.bak.v3-<timestamp>`, renders skill packages, re-validates token
  registry, prints summary. Idempotent.
- **Profile classification:** `canRunCommands=true → admin`; `canWrite=true`
  and `canUseClipboard=true → standard`; metadata-only → `safe`; profiles
  with redact-field overrides that don't match a preset → `custom`.
- **`docs/migration-v3-to-v4.md`** — full user-facing upgrade guide.
- **`docs/skills/symaira-agent/UPGRADE-TO-V4.md`** — AI-agent-ready prompt
  to drive the upgrade end-to-end.

### Security

- Memory hygiene: TOTP secret, OPENPASS_PASSPHRASE, OPENPASS_MCP_TOKEN string
  backing arrays wiped after read; passphrase wiping via `[]byte` instead of
  `unsafe.StringData`; legacy passphrase wiped after migration (#154, #155,
  #158, #159, #177).
- Generated passwords protected with `SecureString` (mlock'd mmap) (#156).
- `SafeMkdirAll` hardened against symlink-traversal attacks (#157).
- `unsafe.StringData`/`unsafe.Slice` removed from TOTP input handling.
- Prompt-injection hardening: 4 fixes + threat model + e2e tests; per-tool
  `redactFields`, registry hash, tool-chain anomaly detection, import
  quarantine (#91-95, #97).
- API response sanitization for `execute_api_request` (#57, #62).
- `generate_totp` hardened: default clipboard, return-value gated on approval
  (#59).
- 32 + 27 + 15 + 6 + 5 gosec/code-scanning alerts resolved across
  the v3→v4 cycle (#121, #122, #123, #137 et al).

### Fixed

- `--dry-run` no longer creates real tokens in `mcp install` (#68).
- Token registry reloads when the file changes on disk (#67).
- Opencode install uses the correct root key and adds required fields (#66).
- `symvault auth status --output json` uses `PrintResult` instead of the
  deprecated `PrintJSON` (#180).
- `migrateLegacyEntries` walks skip `IsNotExist` errors instead of bailing
  out.
- 2 `goconst` lint findings in `internal/config/config_load.go` and
  `config_merge.go` resolved by reusing existing constants.

### Performance

- `EnforceRetention` uses `os.ReadDir` instead of `filepath.Glob`
  (orders-of-magnitude faster on large vaults) (#161).

### Refactored

- `init()` functions replaced with explicit package-level initialization
  (#162).
- `copyAgentProfiles` replaced with JSON deep-copy (#178).
- Session passphrase wiping uses `[]byte` instead of `unsafe.StringData`
  (#177).

### Documentation

- Expanded error-wrapping conventions in `CONTRIBUTING.md` (#163).
- Added CVE monitoring guidance for the deferred ProtonMail/go-crypto
  transitive dependency (#179).
- Added v4 release checklist (`docs/release-checklist-v4.md`).

## [v3.0.0] - 2026-05-15

### Added

- **Security: MCP response hardening** — new `taint.Untrusted` typesystem provides compile-time safety boundary between trusted and untrusted data; all MCP responses pass through `SanitizeForMCP` chokepoint; new `EmbedAsData()` helper wraps untrusted content in safe `<data>` tags; all 12 prompt injection points migrated to `EmbedAsData` (#38, #40)
- **Security: typed vault accessors** — `FieldUntrusted()`, `TagsUntrusted()`, `UsageHintUntrusted()` return `taint.Untrusted` values with provenance tracking; `SecretHandle` type with `ParseSecretHandle()` for `op://` path resolution; `HandleResolver` interface (#39)
- **Security: `CanReadValues` profile option** — gates `get_entry_value` behind explicit agent permission; `requireApproval()` helper with `Intent` struct, `ApprovalMode` (none/auto/deny/prompt), and audit-logged approval/rejection events (#40)
- **Security: custom Go vet analyzer (`passlint`)** — detects `fmt.Print*/Sprintf/Fprint*` with `taint.Untrusted` args; integrated into CI via `make vet` (#42)
- **Terminal output hardening** — all TUI, Doctor, and CLI output sanitized through `render.ForTerminal()` and `ForTerminalLine()` (#41)
- OAuth refresh token grant (RFC 6749 §6) with configurable TTLs (`ScopedToken` gains `RefreshTokenHash`/`RefreshExpiresAt`; `CreateWithRefresh()`/`RotateViaRefreshToken()`; single-use rotation) (#46)
- Persistent OAuth client registry — client registrations survive server restarts via JSON persistence (`oauthClientStore.Load()`/`Save()`); optional TTL with background expired-client cleanup (#45)
- Config options `mcp.oauth.access_token_ttl` (default 24h) and `mcp.oauth.refresh_token_ttl` (default 720h/30d) with file config + merge support (#46)
- Nix flake for NixOS/Nix support — `nix run github:danieljustus/symaira-vault` with `buildGoModule` package, default app, and dev shell (#36)
- New `internal/ui/render` package with `ForTerminal()`, `QuoteForTerminal()`, `ForTerminalLine()` sanitizers
- New `internal/mcp/render.go` with `RenderChokepoint` and `SanitizeForMCP()`

### Changed

- **Breaking: MCP `get_entry` response format** — `fields` now `[]map[string]{name, handle, kind}` instead of `[]string`; each field includes type-inferred `kind` (string, number, boolean, totp, object, null) (#40)
- **Breaking: `include_value` removed** — `handleGet` returns metadata only; `handleSanitizeOutput` delegates to `SanitizeForMCP` chokepoint (#42)
- **Breaking: prompt format migrated** — all user-supplied values in MCP prompts are now wrapped in `<data label=..>` tags with `(data)` annotation, removing `%s`/`%q` injection risk (#40)
- OAuth docs updated to reflect live OAuth implementation (removed "501 Not Implemented" claims) (#47)
- Agent integration docs: added OAuth DCR section with opencode configuration example (#47)
- `get_entry_metadata`: `UsageHint` sanitized through `SanitizeForMCP`
- `list_entries`/`find_entries`: `Path` and `UsageHint` sanitized through `SanitizeForMCP`
- `set_entry_field`/`delete_entry`: use `requireApproval()` instead of `requiresApproval`
- Bumped `github.com/mattn/go-runewidth` from v0.0.19 to v0.0.23 (#44)
- Bumped `actions/upload-artifact` from 4 to 7 (#43)
- `gocyclo` complexity threshold adjusted to 30 for existing codebase

### Fixed

- OAuth error response: `unauthorized_client` → `invalid_client` with `WWW-Authenticate` header (#45)
- Nix `vendorHash` resolved for reproducible builds (#36)
- `err` shadowing in `handlerForAgent` goroutine closure
- `gofmt` formatting across `config.go`, `taint_test.go`, `schema.go`, `token.go`, `oauth.go`, and test files
- `errcheck`: handle `fmt.Fprintf` return values in `taint.go`
- `goconst`: use `SecretTypePassword` constant in `types.go`
- `govet shadow`: rename `err` variables in `tools_delete.go` and `tools_get.go`
- `prealloc`: preallocate slice with capacity in `approval_helper.go`
- `unconvert`: remove unnecessary `string()` conversion
- `unused`: remove dead `buildVaultResolver` function
- Skip file permission assertion on Windows (`chmod` is no-op on Windows)
- `goimports`: formatting on `passlint_test.go`

## [v2.9.0] - 2026-05-13

### Added

- Weak password support: `AssessPasswordStrength` (non-blocking) alongside `ValidatePasswordStrength`, weak passwords accepted with confirmation in TTY mode, `--force` for scripted use, automatic `weak-password` tag on entries, and new doctor checks `password.strength` and `password.reuse` (#35)
- Centralized TUI theme system with visual polish and Esc-to-confirm (#33)
- Doctor enhancements: tag-based check filtering (`--quick`), 9 new checks (auto-type backend, clipboard, daemon, MCP server, dynamic secrets, agents, secure UI, pre-commit hooks, session keyring), `--fix-dry-run` flag, schema_version output (#31)
- Agent auto-install support for Codex and OpenCode alongside existing Claude Code config (#32)
- Theme symbols and styletheme packages for consistent UI styling

### Changed

- Wizard UX improvements: summary highlight, MultiDevice default to No, Enter-to-save on empty textarea, progress spinner with step counter, resume prompt with file age, passphrase autofocus, vault path validation, resume file moved to UserCacheDir with 0600 perms (#30)
- TOML config reader/writer (`FormatTOML` constant) for agent config generation

### Fixed

- Security: OAuth flow now requires client registration, TTY consent, and returns scoped tokens (#21)
- Security: `list_shares` scoped to calling agent instead of showing all grants (#22)
- Security: authorization gates (CanRunCommands, allowlist, approval) on `generate_dynamic_secret` (#23)
- Security: passphrase heap copy eliminated via `unsafe.String` aliasing before Wipe (#26)
- Security: Origin header warning + `approve_share` self-approval check (#27, #29)
- Security: global cooldown replacing per-guess failed-attempts map (#25)
- Removed `generate_dynamic_secret` tool (dead code — engines never registered) (#24)
- Removed duplicate `logAuditWithToken` helper (#28)
- Resolved 13 golangci-lint issues (errcheck, goconst, gocritic, govet, unused)
- Added timeout to `checkSessionKeyring` to prevent hang on headless macOS CI
- Lowered coverage threshold to 68.0% to match current baseline
- Added #nosec annotations for gosec G103/G304 false positives (10 alerts)
- gofmt formatting fixes across test files

## [v2.8.2] - 2026-05-12

### Fixed

- Resolve gosec code scanning alerts (G115, G302, G304):
  - Add overflow bounds check for int32 conversion in `SetTestScryptWorkFactor`
  - Fix nosec annotation format for directory permissions check
  - Fix nosec annotation format for controlled file read

## [v2.8.1] - 2026-05-12

- Security hardening, concurrency locking, and audit error handling
- Resolve golangci-lint errors (prealloc, errorlint, errcheck)
- Fix test helper vars and Windows LockFileEx test skipping

## [v2.8.0] - 2026-05-12

### Added

- MCP **Prompts** capability with four slash commands surfaced in Claude Code, OpenCode, Hermes and other MCP clients: `add-credential`, `rotate-credential`, `find-and-use`, `share-credential`. Each prompt renders a guided workflow that the agent follows step-by-step (e.g. `/mcp__openpass__add-credential` walks the agent through collecting a new secret without ever exposing the value)
- `request_credential` MCP tool — the agent calls this when it discovers a credential is missing from the vault during a task; the user gets a native input dialog, types the value, and it lands in the vault without ever transiting the chat
- New `internal/secureui` package providing cross-platform secure input: native macOS dialogs via `osascript`, Linux dialogs via `zenity` or `kdialog`, Windows credential prompts via PowerShell `Get-Credential`, with the existing TTY backend as a fallback. Backend selection honors a new `OPENPASS_SECUREUI=tty|gui|none` environment override
- `auth_rotate` CLI command for credential rotation
- `verify` CLI command for vault integrity checks
- `internal/audit/keystore` with OS-level and fallback backends
- `internal/crypto/diceware` passphrase generator with EFF large wordlist
- Multi-device QR pairing in wizard
- Wizard state persistence
- Vault manifest for metadata tracking
- OAuth well-known endpoints for MCP server discovery

### Changed

- `secure_input` MCP tool is now available in HTTP mode as well, provided the host has a native dialog backend (previously stdio + TTY only)
- Server initialize response now advertises the `prompts` capability so clients enable the slash-command surface
- Doctor checks expanded for crypto KDF modern status and keystore health
- Vault entry, lock, reencrypt, and search improvements

## [v1.0.0] - 2026-04-22

Initial stable Symaira Vault release.

### Added
