Sahil BansalandGitHub 94781d6bda Remove guard mode: proxy interception is now the only flow (#386)
* refactor: remove guard mode execution paths and guard-only packages

Guard (non-proxy) mode is removed; all package-manager commands now
always run the proxy flow. Removes the guard engine, the common flow,
the extractor package, the npm/pypi dependency resolvers and the
PackageResolver plumbing that only guard mode consumed.

The guard package retains only PackageManagerGuardInteraction, which
the proxy flow and confirmation interceptors reuse for user prompts.
Proxy behavior is unchanged.

* refactor: remove proxy opt-out surfaces, guard references in config, action and docs

Removes Config.ProxyMode, ProxyConfig.Enabled, IsProxyModeEnabled, the
proxy_mode legacy fallback, PMG_PROXY_ENABLED handling and the
--proxy-mode / --include-dev-dependencies flags. Proxy interception can
no longer be disabled.

Also removes the proxy-mode input from the GitHub Action, the
proxy-mode doctor check and setup info row, updates the E2E workflow to
stop passing --proxy-mode=false, and sweeps guard-mode wording from
docs and the config template.

The legacy proxy_install_only flat key and PMG_PROXY_INSTALL_ONLY env
var remain supported. audit.FlowTypeGuard is kept so previously
recorded audit events still translate for cloud sync.

* feat: fail loudly when a removed proxy opt-out is still configured

A leftover proxy.enabled: false / proxy_mode: false config key or
PMG_PROXY_ENABLED=false / PMG_PROXY_MODE=false env var previously meant
guard mode; silently ignoring it would switch those users to proxy
interception without notice. PMG now exits with an actionable error
naming the exact source. Precedence mirrors the old resolution order:
env (ignored under lockdown) > proxy.enabled > legacy proxy_mode.

The pmg config subtree is exempt so the config file can still be fixed
with pmg config edit/set. The GitHub Action's proxy-mode input is kept
as a tombstone that fails the action when set to false and warns
otherwise.

* refactor: extract flows.RunProxy and address review findings

Collapses the identical parse-then-run body duplicated across the 12
package manager commands into flows.RunProxy. Documents the cache-hit /
offline analysis trade-off versus the removed guard manifest path,
fixes a stale non-proxy label in the E2E workflow and a stale guard
reference in the uvx parser comment.

* fix(config): mirror old proxy opt-out precedence exactly

PMG_PROXY_MODE only ever took effect through the legacy fallback, which
was gated on the presence of a proxy: key in the config file (even a
null one). Promoting it to the top env tier caused two inversions: a
stale PMG_PROXY_MODE=false hard-failed configs that resolved to proxy
mode, and PMG_PROXY_MODE=true silently overrode an explicit
proxy.enabled: false file opt-out. The check now resolves in the old
order: PMG_PROXY_ENABLED > proxy: section (presence gates the legacy
tier) > PMG_PROXY_MODE > flat proxy_mode.

parseOptOutBool also accepts numeric values (0 = false) to match
viper's WeaklyTypedInput/cast.ToBool coercion, so proxy.enabled: 0 and
proxy_mode: 0 are detected as opt-outs.

* refactor: move package manager interaction out of guard

* refactor: trim package manager interaction

* fix(config): normalize config keys viper-style in proxy opt-out check

Viper resolved config file keys case-insensitively and expanded dotted
keys, so spellings like Proxy:, Enabled:, a literal proxy.enabled key or
Proxy_Mode selected guard mode before the removal. The opt-out check now
lowercases keys recursively and nests dotted keys before matching, so
those existing opt-outs fail loudly instead of being silently ignored.

* refactor: remove inert transitive controls, dead parser state and guard audit variant

transitive / transitive_depth lost their only consumers with the
dependency resolvers; remove the config fields, flags, template and doc
entries, and the report/audit plumbing that misreported transitive
analysis as enabled.

Remove write-only parser state (PackageInstallTarget.Extras,
ParsedCommand.ManifestFiles, ShouldExtractFromManifest); IsManifestInstall
stays as it feeds sandbox gating via IsInstallationCommand.

Remove audit.FlowTypeGuard and its cloud mapping; guard events recorded
by pre-removal versions in an unsynced WAL translate to UNSPECIFIED.

* fix: address review findings on the opt-out wiring and cleanups

Move the removed-opt-out rejection from the CLI PersistentPreRun into
proxyFlow.Run: the check now fires exactly for package-manager runs, so
non-install commands (pmg setup remove, doctor, config, version) stay
usable to fix or remove an opted-out installation, and future commands
inherit or avoid the check by construction instead of by exemption list.

Also: make the e2e malicious-package assertion actually fail the job
when an install is not blocked, route pmg go through flows.RunProxy,
and drop the dead extras return from pypiParsePackageInfo (extras are
still stripped from package names).

* fix(config): make the removed opt-out check faithful to the old resolution

The gate that silenced the legacy proxy_mode surfaces matched the raw
proxy key case-sensitively in the old code, while values resolved
viper-style (case-insensitive, dotted keys); applying each semantic
where the old code did fixes both divergences: a case-variant Proxy:
section no longer hides a flat proxy_mode: false opt-out, and a dotted
proxy.enabled: false overridden by proxy_mode: true no longer errors.

Replace the generic key-tree normalization with two targeted lookups
(the check only ever resolves proxy.enabled and proxy_mode), which also
makes colliding spellings resolve deterministically. Coerce legacy-tier
values cast.ToBool-style so PMG_PROXY_MODE=off style opt-outs are
detected, log the config read error instead of swallowing it, and
shorten the error to a one-line statement with the specific remedy in
the help text.

Add lockdown coverage (env inert both directions) and a repeated-run
determinism test.

* fix(config): fall back to defaults for unrecognized proxy opt-out values

The old loader swallowed viper errors and ran on defaults, so values
like proxy.enabled: yes or PMG_PROXY_ENABLED=banana silently discarded
the whole config and defaulted to proxy. Treat them the same way now:
unrecognized values mean the default (proxy on) instead of a hard
error, and the doc comment no longer claims the old loader failed
loudly. Only values that actually meant guard mode fail.

Also check the removed opt-out before the CA trust check in pmg go,
restoring the old error precedence: a config problem must not steer
the user into an unnecessary OS trust store change.

* fix(e2e): PMG_PROXY_MODE assertion must match the legacy gate semantics

The runner's setup step writes the template config, which has a proxy:
section — and with one present the legacy PMG_PROXY_MODE was always
inert, so expecting a loud failure there asserts pre-fidelity-fix
behavior. Assert both sides instead: inert (command succeeds) with the
standard config, loud failure against an empty config dir where the
legacy fallback actually applied.

* refactor(config): collapse parseOptOutBool to ParseBool over the string form

YAML hands us typed values (bool, int), so route them through
fmt.Sprintf %v and strconv.ParseBool instead of a per-type switch.
Identical behavior for every recognized value; numbers other than 0/1
now read as no opinion instead of cast.ToBool's nonzero-true, which no
real config relies on.

Sahil BansalandGitHub 5ac0f275b8 feat(proxy): emit session summary on persistent proxy shutdown (#352)
* feat(proxy): emit session summary on persistent proxy shutdown

The persistent proxy daemon never ran the per-invocation flow that calls
LogSessionComplete, so no session summary reached the cloud for server-mode
runs. Emit one from the daemon's aggregate stats collector on shutdown,
before the final cloud flush, so it is delivered with the run's events and
carries the CI/invocation context.

Extract the event emission into a shared LogSessionSummary(SessionData); both
the per-invocation flow and the daemon now use it. The daemon serves every
package manager, so the summary carries no single package manager.

* chore(action): shorten default cloud endpoint id prefix to gha/

c47776db27 feat(proxy): persistent proxy server mode (#351)
* refactor(flows): extract SetupCACertificate for reuse

Move the CA load/generate/merge logic out of proxyFlow into an exported
flows.SetupCACertificate so the persistent proxy server can reuse it.

* feat(proxy): add persistent proxy server with start/stop/env/status

Introduces 'pmg proxy' commands backed by internal/proxyserver: a long-lived
MITM proxy that intercepts package managers via env vars (no shims). Supports
--daemon (Unix), --state, --port; generic 'env' output that skips cert vars
when the CA is OS-trusted; opt-in 'stop --fail-on-violation' (fail-closed on
crash) with a synchronous cloud event flush; and the malysis analysis cache.

* feat(action): add server-mode for persistent proxy

When server-mode=true the action starts the proxy daemon and injects proxy
env vars into the job instead of installing shims.

* test(proxy): add persistent proxy server E2E workflow

* docs(readme): document persistent proxy server mode

* fix(proxy): create cache dir before writing state file and daemon log

On a fresh CI runner the cache directory does not exist yet; os.OpenFile and
os.WriteFile do not create parent dirs, so 'pmg proxy start --daemon' failed
with 'no such file or directory'. MkdirAll the parent before writing.

* docs: add persistent proxy server architecture doc

* refactor proxyserver

* fix(proxy): always emit cert env vars instead of skipping on OS-trust status

npm/pip/yarn/requests trust the MITM CA inconsistently across tools, versions,
and configs; many still use bundled CA stores. Always emitting the cert-path
env vars is the conservative choice that works regardless, and is harmless for
tools that read the OS store (they ignore the vars). Skipping them when a
system CA exists would silently break any tool still on a bundled store.

* refactor(proxy): drop redundant audit init in daemon; rely on main.go

main.go's PersistentPreRun already initializes the audit pipeline for every
command (including the daemon's re-exec'd child) and closes it at process exit.
Re-initializing in proxyserver.Run created a second auditor and a second
cloud-sync WAL connection, orphaning the first. Removing it makes the daemon
consistent with the normal proxy flow, which never self-initializes audit.

* fix(proxy): bypass proxy env when flushing events to cloud on stop

pmg proxy stop inherits HTTP(S)_PROXY (injected by 'pmg proxy env') pointing at
the PMG proxy it just shut down. The cloud sync gRPC client honored those vars
and routed api.safedep.io through the dead proxy, failing with 'connection
refused' so no events were delivered. Clear the proxy env vars before the sync
so PMG's own cloud traffic goes direct.

* chore(proxy): address review feedback

- configurable bind host via proxy.server.listen_host (default loopback)
- proxy commands use ui.ErrorExit instead of returning errors to cobra
- rename errcode to ProxyPolicyViolation (covers malware + cooldown)
- share cloud sync via audit.DrainToCloud (de-dup with cmd/cloud/sync)
- centralize proxy CA bundle path in certmanager
- docs: persistent proxy cert trust + bind address

* fix(proxy): show real message on fail-on-violation error

stopExitError set only WithMsg, but ui.ErrorExit renders HumanError, so the
framed error showed 'no human-readable message available'. Set both from one
string, and emit the framed error before the stdout summary so the blocked
count is stated once.

* fix(proxy): flush cloud events from the daemon, not stop

The stop process inherits HTTP_PROXY (from 'pmg proxy env'), so its cloud
client routed api.safedep.io through the already-stopped proxy and failed with
connection refused. Move the flush into the daemon's shutdown, which has no
proxy env (it started before env injection) and dials SafeDep directly.

- daemon flushes on shutdown via audit.DrainToCloud and records the result in
  the state file; stop surfaces it (on both success and fail-on-violation
  paths) since the daemon's own logs aren't visible to stop
- coordinate stop's wait with the daemon shutdown budget; on timeout, error
  out without reading stale state or deleting the file (fail-closed)
- persist blocked count before the flush so the gate stays correct if the
  flush hangs or the daemon is killed mid-flush
- remove now-redundant cloud_flush.go

* disable auto-sync for proxy cmds

* feat(proxy): periodic cloud sync + move proxy env vars to packagemanager

- daemon runs a periodic cloud-sync ticker so the shutdown flush stays small;
  the run total is reported by stop, and shutdown timeouts are coordinated
- move EnvVarForProxy from config to packagemanager (it is package-manager
  knowledge); the shared function now builds the proxy URL and NO_PROXY itself,
  removing the duplicated construction in the per-command and persistent paths
- relocate the #319 yarn and #339 IPv6 regression tests alongside the function
- enable cloud sync in the persistent-proxy E2E workflow and fix the stale
  internal/proxystate path filter

* refactor(proxy): rename cloudFlushLockTimeout to cloudFlushLockWait

Consistent timeout naming: *LockWait is the lock-acquire bound, *Timeout is
the sync-RPC bound. Previously the final-flush pair was cloudFlushLockTimeout
vs cloudFlushTimeout — two lookalike names for different operations.

* refactor(proxy): extract cloudFlush and trim duplicate shutdown comments

The shutdown's final-flush block is now a cloudFlush helper, symmetric with
startCloudSyncLoop (one-shot vs loop). Removed the triplicated ticker/lock
contention comments, keeping the contract on the function doc and one-line
pointers at the call sites.

* docs: update persistent proxy cloud sync to daemon-owned model

The daemon now owns cloud delivery (periodic sync while serving + final flush
on shutdown); stop signals it, waits, and reports the result. Rewrite the Cloud
event sync section, fix stop attributions, add the cloud_sync state field, and
update the sequence diagram.

* docs: move Usage section up below How it works

Put the copy-paste recipes near the top so users find them before the internals.

* refactor(proxy): address PR review feedback

- configurable bind host/port via --host/--port flags + config (listen_host,
  listen_port), bound directly to config fields per PMG's flag pattern
- daemon log path via --log-file and readiness timeout in ProxyDaemonConfig;
  Daemonize no longer owns path policy (caller validates, fails fast)
- gate periodic cloud sync on auto_sync; suppress detached background sync for
  proxy commands instead of flipping the flag
- pmg proxy env --export emits shell-quoted lines for eval (spaces survive)
- extract shared flows.BuildCachedMalysisAnalyzer, dropping the analyzer+cache
  duplication between proxy flow and proxy server
- add internal/proxyserver/doc.go documenting the package + boundary vs flows
- E2E: assert malicious installs are blocked (drop continue-on-error)
- docs: trim Commands/State-file to user contracts; refresh bind address

* refactor(proxy): proactive alignment fixes from whole-PR review

- gate the shutdown cloud flush on auto_sync too, matching the periodic ticker
  (auto_sync consistently controls all daemon-driven cloud delivery)
- ResolveStatePath takes cacheDir instead of *RuntimeConfig, keeping state.go
  free of config dependency
- drop the empty-host comment in listenAddr; keep the loopback guard so a blank
  host never silently binds all interfaces

* fix: Decouple localdb with malysis analyser construction

* fix: Persist global args before proxy server daemon exec

* fix: GitHub Action for cloud auto-sync in server mode
