Getting Claude Code onto Cortex went from nine commands and three environment
variables to two commands and none. Most of this PR is the things that had to be
true first — found by executing the instructions rather than reading them.

What a user does now

# once
curl -fsSL https://raw.githubusercontent.com/rossoctl/cortex/main/authbridge/install.sh \
  | sh -s -- --claude-code

# forever after
claude          # in one terminal
abctl           # in another

Before: nine commands including a 25-line YAML heredoc, a sed to substitute
$HOME, three exported variables on every claude, and --endpoint http://localhost:47601 on every abctl.

New user-facing surface

abctl claude-code enable | disable | status — writes HTTPS_PROXY,
NODE_EXTRA_CA_CERTS and CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC into the
env block of ~/.claude/settings.json, so claude needs no shell variables.
Claude Code's own network docs say settings is not merely tidier but more
correct
: its supervisor is one process shared by every terminal and inherits
whichever shell cold-started it, so an exported proxy or CA path reaches
background agents only by luck.

Addresses are read from ~/.cortex/config.yaml, never hardcoded. It writes only
those three keys, leaves every other setting byte-identical (including
ANTHROPIC_BASE_URL and any auth token), backs the original up once and never
overwrites that copy, writes atomically because Claude Code watches the file,
refuses when HTTPS_PROXY is already set to something else, refuses to overwrite
settings it cannot parse, and is idempotent. install.sh --claude-code prompts on
/dev/tty — stdin under curl | sh is the script itself.

abctl with no flags connects to the Cortex on this machine when one is
answering, instead of demanding kubectl and opening a cluster picker. A stale
config from a stopped install does not hijack the picker. The [l] key was
hardcoded to :9094, the in-cluster port, so on every laptop it connected to the
wrong place; it now uses the same resolved address.

abctl tools scan --all scans every transcript instead of a 30-day window.
Wider is the cautious direction — a longer window finds more tools in use, so it
prunes less. --days 0 is rejected rather than read as "everything", since a
zero-width window finds nothing used and would propose removing everything.

One config, one CA, one directory. ~/.cortex/config.yaml plus
~/.cortex/ca, created 0700. --demo is now --local, install-demo.sh is
install.sh, and nothing is written to the working directory.

Build-matrix coverage. ci.yaml now builds abctl and authbridge-praxis
too — both ship or live in-tree and neither was in any workflow, which is how the
release-breaking go.sum gap below reached main.

Release-blocking bug this fixes

abctl did not build in release. #849 added a gjson import to
authlib/pipeline without updating cmd/abctl's go.mod; abctl resolves authlib
through a replace, so GOWORK=off go build — exactly what
release-binaries.yaml does — failed on a missing go.sum entry. Every other
build path uses the workspace, which masked it. Tagging before this merges would
publish a release with no abctl for any platform.
Root cause: ci.yaml's matrix
covered authbridge-proxy and authbridge-envoy but not abctl. Both abctl and
authbridge-praxis (broken the same way, in no workflow at all) are now in it.

Other fixes

  • A fatal error logged at INFO. slog.SetDefault routes the std log package
    at Info, and all 24 startup failures use log.Fatalf — so a port clash printed
    as INFO and the process exited. One SetLogLoggerLevel call.
  • Health port was a hardcoded ":9091", so two proxies could never coexist.
    Now listener.health_addr, defaulted to ":9091" by every preset.
  • The laptop config bound :8082 and :9091 on every interface. All five
    listeners pinned to loopback. transparent_proxy_addr is pinned even though
    --local skips it, because the docs tell people to start the same file with
    --config, which does not.
  • A CA and private key landed in the working directory — including inside this
    repo during testing, with no gitignore rule to catch it.
  • The scan would write a removal list inferred from nothing. With zero observed
    calls, "tools you have not called" is every tool it knows — a 26-name list
    including BashOutput and KillShell. That is a new install, which is when the
    default is most likely accepted. It now refuses, and warns on thin evidence.
  • --lite omitted exclude_plugin_toolprune in two of four copies of the tag
    list, compiling in a plugin whose RequiresAny: [inference-parser] lite
    excludes. See the note on refactor: ♻️👷 Use common tags for plugin lite builds #861 below — that PR now owns this.
  • Non-string values in settings.json's env block were silently dropped.
  • NODE_EXTRA_CA_CERTS was written without checking the file exists — the silent
    trust-anchor failure. Now warned.

Review rounds

Round one (12 findings) and round two (8) are addressed in 5f654ecf and
1ab308fd. Two were mine and worth naming:

  • stop_previous_cortex never ran on Linux. authbridge-proxy is 16
    characters and Linux caps comm at 15, so ps -o comm= returns
    authbridge-prox and the glob never matched. macOS does not truncate, which is
    why testing on a Mac passed.
  • The session-budget doc was correct before I touched it: it passes -config
    explicitly, and that config's ca_dir is cwd-relative. I replaced accurate
    wording with a path that does not exist, and a missing NODE_EXTRA_CA_CERTS
    fails silently.

Verification

  • Full release matrix (16 artifacts, 4 platforms) builds with GOWORK=off
  • The documented flow runs end to end: one command installs, writes one config,
    starts with all four plugins live on /v1/pipeline, and re-running replaces the
    previous instance
  • Gateway mode was tested while exploring options (4 tools in, 2 out, real 401
    from api.anthropic.com) but is not part of this PR
  • --local from a scratch directory leaves the cwd empty; the migration warning
    fires on a stale ./cortex-ca; --ca-dir still redirects
  • settings.json merge preserves a token byte-identically; the env-preservation
    test was mutation-checked against the old code
  • Five modules build/vet/test clean; authlib passes -race; shellcheck clean on
    three scripts; four workflows parse

Relationship to #861

This PR originally centralized the exclude_plugin_* tag list in a
LITE_BUILD_TAGS file. #861 solves the same duplication and solves it better —
its authbridge/scripts/lite-tags generator derives the list from the
//go:build !exclude_plugin_<name> markers, so a new plugin is excluded from lite
automatically rather than when someone remembers to edit a file.

Ours has been dropped (d10039d5). This PR no longer touches build.yaml,
release-binaries.yaml or local-build-and-test.sh at all, and merges into
#861 with zero conflicts
(verified; it was four before).

One dependency that creates: release-binaries.yaml on main still omits
exclude_plugin_toolprune, so until #861 lands the published -lite binary
compiles tool-prune in. Harmless — bytes only, and it cannot satisfy
RequiresAny: [inference-parser] there — but re-adding the one-line fix here
would recreate the conflict, so #861 should merge.

Not in this PR

  • Gateway mode (ANTHROPIC_BASE_URL → Cortex) removes the CA entirely but only
    sees Anthropic traffic, not MCP/A2A. Worth considering for the cost page later.
  • While enabled, claude depends on Cortex running. abctl claude-code disable is
    the off switch; starting Cortex at login would remove the caveat.

    • Improved IPv6 endpoint handling and startup error reporting.
    • CA directories now use more restrictive permissions.
  • Documentation

    • Updated quick-start, local setup, tool-pruning, ports, and installation guidance.

The quickstart asked a teammate to run nine commands, two of which were a
25-line YAML heredoc and a sed to substitute $HOME into it, and it spent
three paragraphs explaining that `VAR=1 curl ... | sh` sets the variable on
curl rather than sh. It is now three commands and no gotchas.

Most of this commit is the things that had to be true first. Trying to
follow my own instructions end-to-end is what found them.

**abctl was broken in release builds.** rossoctl#849 added a gjson import to
authlib/pipeline without updating cmd/abctl's go.mod, and abctl resolves
authlib through a replace directive, so `GOWORK=off go build` — exactly what
release-binaries.yaml does — failed on a missing go.sum entry. Every other
build path uses the workspace, which masked it. Cutting a tag today would
have produced a release with no abctl for any platform. Root cause is that
ci.yaml's matrix covers authbridge-proxy and authbridge-envoy but not
abctl, so a binary we publish was never built in CI; abctl is now in the
matrix.

**A fatal error was logged at INFO.** slog.SetDefault also routes the
standard log package, at Info unless told otherwise, and all 24 startup
failure paths in main.go use log.Fatalf. So a port clash printed as an INFO
line and the process exited — the log looked clean and the proxy was gone.
One SetLogLoggerLevel call fixes every one of them. Fatals are the only
std-log users in these binaries, so nothing else gets mislabelled.

**The health port was a hardcoded ":9091".** Two proxies could therefore
never coexist on one host: the second died on a bind conflict, which is
precisely what happens when a teammate follows the quickstart while a demo
is already running. It is now `listener.health_addr`, defaulted to ":9091"
by every preset so Kubernetes probes are unaffected.

**The documented laptop config bound two ports on every interface.**
:8082 (transparent egress) and :9091 came from preset defaults the config
never overrode, so a laptop on an untrusted network exposed both. The
generated config now pins all five listeners to loopback. Note that
transparent_proxy_addr cannot be disabled under proxy-sidecar — the preset
refills an empty value — so pinning it is the available fix, not omitting
it.

**The scan would write a removal list inferred from nothing.** With zero
observed tool calls, "tools you have not called" is every tool it knows:
a 26-name list including BashOutput and KillShell, which background tasks
need. That is not an edge case, it is a new install — little history, and
the moment someone is most likely to accept the default. `--write` now
refuses when the scan saw no tool calls, prints the proposal anyway, and
says what to do instead. The paired test covers both directions so the
guard can't pass by never writing.

The installer grows `--claude-code`, which writes a persistent config under
~/.cortex (not the ./cortex-ca/demo.yaml that --demo regenerates on every
start, discarding edits), fills the remove: list, starts the proxy, and
prints the run command. Flags replace the env-var form because `sh -s --`
has no variable-placement trap; AUTHBRIDGE_INSTALL_ONLY still works.
AUTHBRIDGE_SKIP_DOWNLOAD is new and is what let me test all of this
without a published release.

$HOME in the generated config is left literal: authbridge expands
${ENV_VAR} at load, so the file stays portable and needs no sed.

Verified: the full release matrix (16 artifacts, 4 platforms) builds with
GOWORK=off; the documented flow runs end to end on shifted ports, writes
the same 15-tool list as a hand-built config, and comes up with all five
listeners on loopback; shellcheck clean at every severity.

Check all generated listener ports before startup.

Claude Code mode binds ports 47603 and 47604, but this loop checks only 47600-47602. If either omitted port is occupied, the proxy can fail after the scan and configuration setup complete. Check all five ports and report the ~/.cortex/config.yaml path for this mode.

Comment thread authbridge/install-demo.sh Outdated
The persistent setup already lived in ~/.cortex, but --demo did not: it
defaulted to ./cortex-ca, relative to whatever directory it was started
from. So the CA and its private key landed wherever you happened to be —
including inside a checkout of this repo, which is exactly what happened
here during testing, and .gitignore had no rule that would have caught it.

--demo now defaults to ~/.cortex/demo. One directory per user holds config,
CA, keys, logs and pidfiles; nothing is written to the working directory at
all, which the test confirms by asserting the cwd stays empty.

The old default was justified in a comment as avoiding an absolute path
baked into the binary. Resolving $HOME at runtime satisfies that just as
well, and the cwd default had a cost the comment did not weigh: a private
key dropped into arbitrary directories, and a CA path that changed
depending on where you launched from — which is precisely the thing the
session-budget demo doc had to spend a paragraph explaining how to
recover with `ls "$(pwd)/cortex-ca/ca.crt"`. That paragraph is gone.

--demo keeps its own subdirectory rather than sharing config.yaml, because
it regenerates its config; sharing would mean it could clobber a config
someone maintains by hand.

Because these directories now hold a private key in a predictable place,
they are created 0700 (previously 0755).

Migration: the default moving is a silent failure for anyone whose client
already trusts a CA in ./cortex-ca — requests just tunnel through opaquely
and no plugin sees a body. So --demo warns when it finds a ./cortex-ca it
is no longer using, naming both paths and the two ways forward (update the
client, or pass --ca-dir ./cortex-ca). --ca-dir still overrides, verified.

Also adds a cortex-ca/ gitignore rule, which covers both the no-resolvable-
$HOME fallback and an explicit --ca-dir, so a private key cannot be
committed from a demo run inside a checkout.

Docs updated to the single location: the quickstart now shows the ~/.cortex
tree and how to uninstall it, and the root README, tool-prune reference,
session-budget demo, and abctl's missing-config hint all name the new path.

Verified: --demo from a scratch directory writes only under ~/.cortex/demo
(0700, key 0600) and leaves the cwd empty; the migration warning fires on a
stale ./cortex-ca; --ca-dir still redirects; --claude-code produces exactly
the tree the doc documents; four modules build/vet/test clean; shellcheck
clean.

@huang195 huang195 changed the title Fix: Make the laptop quickstart one command, and fix what blocked it Fix: One-command laptop quickstart, all artifacts under ~/.cortex Sep 3, 2026
Installing Cortex on a machine is the supported way to run it locally, not
a demonstration, so the naming no longer says otherwise.

  install-demo.sh          -> install.sh
  authbridge-proxy --demo  -> --local
  ~/.cortex/demo/          -> ~/.cortex/local/
  ~/.cortex/demo/demo.yaml -> ~/.cortex/local/config.yaml
  demo.log / demo.pid      -> proxy.log / proxy.pid

The config filename now matches the persistent one, so there is a single
name to know regardless of which mode wrote it. Internals follow:
demo.go -> local.go, demoConfigYAML -> builtinConfigYAML, writeDemoConfig
-> writeBuiltinConfig, demoMode -> localMode, defaultDemoCADir ->
defaultLocalDir.

Nothing existing breaks. `--demo` stays a working alias, listed in --help
as deprecated rather than hidden — an empty usage string still prints the
flag, just with a blank description that reads like a bug — and it warns
pointing at --local. install-demo.sh stays as a shim: the old name is in
published release notes, so a command already in someone's history would
otherwise 404. The shim downloads to a file before running it rather than
piping into sh, so a truncated fetch cannot execute as a partial script.

Two things fell out of doing this:

**authbridge-praxis did not build under GOWORK=off** — the same missing
gjson go.sum entry that broke abctl, from the same rossoctl#849 import. It was in
NO workflow: not ci.yaml, not build.yaml, not release-binaries.yaml. That
is why it drifted. Tidied, and added to the CI matrix. cpex stays out
deliberately: it needs CGO and libcpex_ffi.a from a pinned release, so
build.yaml's image build is the right place for it.

**Two comments were quietly wrong.** caTrustPath explained itself with
"--demo anchors the CA to its launch directory", which stopped being true
when the default moved under $HOME; it now gives the reason that still
holds (a client is configured with this path and a mismatch fails
silently). And authbridge-praxis told users to "use --demo for the local
demo" — a flag praxis has never had.

I also introduced two of my own here and caught them by reading the diff
rather than trusting the rename: a blanket --demo -> --local replace turned
the deprecation notice into "--local has been renamed to --local" and
clobbered the comment above it. Both fixed and verified in the log output.

Verified: --local writes ~/.cortex/local/config.yaml and leaves the cwd
empty; --demo still works and warns; --help lists both; installer's
--claude-code, default, and --install-only modes all run end to end;
five modules build/vet/test clean under GOWORK=off; authlib passes -race;
shellcheck clean on both scripts.

Walking the path a new user actually walks — README quick start, then click
through to the token-cost guide — the guide failed at its first command.

Both setups bind the same loopback ports, so the second invocation hit the
port preflight and died: "port 47600 is already in use". The guide is
reached by a link from the README, so that is the common order, not an edge
case.

The installer now stops a Cortex a previous run of it started, and says so.
Deliberately narrow: it only kills a pid from OUR pidfile whose process
name is still authbridge-proxy, because a pidfile outlives its process and
the number can be recycled onto something unrelated. Verified with a
foreign listener holding the port AND our pidfile pointing at it — left
alone, and the preflight still reports the conflict.

**Switching setups changes the CA, and a stale trust anchor fails
silently** — traffic still flows, every request tunnels through opaquely,
nothing is pruned, and nothing looks broken. So when the replaced instance
was the built-in local one, the installer now names both CA paths and says
what happens if the old one is reused. That is the failure this whole
feature is most likely to die of in someone else's hands.

Also fixes a real exposure the rename walked past: the built-in --local
config never pinned health_addr, so the preset filled it with ":9091" —
every interface, on a port common enough to collide. The comment above that
config claimed "every listener the demo uses is pinned to loopback on an
uncommon port", which was simply not true of health. Pinned to
127.0.0.1:47604, matching the --claude-code config, and the comment now
lists health among what a wildcard bind would expose.

Doc wording: the README said "start the demo" and "four steps" (it is three
now), and neither page acknowledged the other. Each now says the guide
takes over from the quick start rather than conflicting with it, so the
"Stopping the Cortex started earlier" line is expected rather than alarming.

Verified end to end: README step 1 starts, the cost guide's step 1 replaces
it and prints the CA note, and both print a working command. Five modules
build/vet/test clean under GOWORK=off; shellcheck clean.

Add a POSIX-shell exception to the strict-mode rule.

authbridge/install-demo.sh runs under sh, and its downloaded authbridge/install.sh also declares #!/bin/sh and uses POSIX syntax. Adding pipefail would break the documented curl ... | sh entry point. Apply an explicit exception to both published POSIX installers rather than adding pipefail to the shim alone.

Comment thread authbridge/install.sh Outdated
The quick start and the token-cost guide read as the same three commands
with a different flag, because underneath they were the same thing.

The built-in config already contained inference-parser AND tool-prune, and
writeBuiltinConfig already preserved edits — I fixed that earlier in this
same series. So `abctl tools scan --write` against the quick start's own
config produced exactly what the second "persistent" config produced, plus
the MCP and A2A parsers. The only real difference was that one of them ran
the scan for you.

I added the second config beside the first instead of noticing the first
already did the work, and everything downstream had to compensate: a second
CA, a second config location, logic to stop one proxy when the other
started, and a warning that the CA path had changed between them. All of
that is now deleted rather than maintained.

There is one config at ~/.cortex/config.yaml and one CA at ~/.cortex/ca.
The binary owns the single config template — the installer no longer
carries a second copy of the YAML, which was its own source-of-truth
problem. --ca-dir now moves only the CA, so relocating a client's trust
anchor can't strand the config somewhere a later command won't look.

The installer fills the prune list by default. That is the point of
installing it, and it is safe to do unattended because `tools scan` refuses
to write when it saw no tool calls to reason from — a brand-new install with
no history gets an empty list and an explanation, not a guess. --no-prune
opts out. --claude-code stays accepted as a no-op alias.

The two pages now divide by content rather than repeating each other: the
README covers install, point an agent at it, watch. The cost page covers
only what it adds — what the saving comes to, how to read the dollar figure,
how to keep the list honest, what does and doesn't change — and links back
for setup. It got shorter (154 lines to 107) by losing duplication, and
gained the per-million pricing example that was only in the plugin
reference.

Also fixes a leftover from the rename: writeBuiltinConfig still logged
"demo mode — keeping the existing config".

Verified: the one command installs, writes one config, prunes 15 tools from
real transcripts, and starts with all four plugins live on /v1/pipeline;
re-running replaces the previous instance and reports the config already up
to date; --no-prune leaves remove: empty; --install-only and --claude-code
both behave. Five modules build/vet/test clean under GOWORK=off; shellcheck
clean.

…thing

--claude-code appears in no instruction on any page — the previous commit
removed the last one — and it survived only as an accepted no-op in
install.sh. I kept it "for compatibility", which does not hold up:

  - it has never existed on main (git log -S finds it only on this branch)
  - the newest release, v0.7.0-alpha.3 from 2026-08-19, predates the commit
    that added it

So it protected nobody, and keeping it meant shipping an undocumented flag
on day one — strictly worse than not having it.

The installer's --demo alias fails the same test, and more plainly:
install-demo.sh on main parsed no command-line flags at all, only env vars.
There is no earlier spelling for anyone to be using.

The proxy's --demo -> --local alias stays, because that one is real: the
flag is at main.go:125 on main and appears in the published README and
release notes. That is the distinction worth drawing — an alias earns its
keep by having shipped, not by sounding cautious.

install.sh now accepts --install-only, --no-prune, and --local (the default,
spelled out, mirroring the proxy flag). An unknown flag names the three.

The previous commit made the installer fill tool-prune's remove list by
default. That was wrong twice over.

The quick start's job is to *observe* an agent's traffic — that is what the
page says it does. Filling the prune list makes it start *rewriting* that
traffic instead, on the first command a new user ever runs, before they have
seen anything the tool does.

And the whole mechanism is Claude-Code-specific: the scan reads
~/.claude/projects, so for anyone driving a different agent it is a mutation
of their requests with no upside at all. Cortex is not a Claude Code tool;
its quick start should not behave like one.

I had reasoned that filling it was safe because `tools scan` refuses to
write without evidence. That defends against a *bad* list, not against
applying a list nobody asked for.

So a fresh install is inert again: tool-prune is in the config with an empty
remove list, no request is modified, and the installer prints the one
opt-in command instead of running it. --no-prune is gone with nothing left
to opt out of.

This also gives the two pages a real division rather than a near-duplicate
one. The README installs and observes. The cost page opens with the single
command that turns pruning on, what it will and won't propose, and how to
undo it — content the README does not have, instead of the same three
commands with a different flag.

Verified: a fresh install reports tool-prune remove=0 on /v1/pipeline and
rewrites nothing; the cost page's one command then writes 15 tools and the
running proxy hot-reloads it (reloads_ok=1, no restart).

Verdict: REQUEST_CHANGES (posted as a comment — GitHub refuses REQUEST_CHANGES on your own PR, so the event is COMMENT; treat the two must-fix items below as blocking).

Genuinely good change — the three-command path works, and I traced every command in it rather than trusting the claim. Two things block, and both are the same shape: a rename that landed everywhere except the places that would have caught it, and a process check that only works on the OS it was tested on.

The two blockers

  1. stop_previous_cortex cannot fire on Linux — authbridge-proxy is 16 characters and Linux caps comm at 15, so the *authbridge-proxy* glob never matches. That is commit 4's headline fix, and it silently does not work on the OS most teammates will use.
  2. ~/.cortex/local/… does not exist anywhere in the code, but this PR introduces it in three places — including a NODE_EXTRA_CA_CERTS value, which is the one variable whose failure mode this PR's own description calls out as silent.

Verified rather than assumed:

  • The three-step quickstart works end to end. Every flag, path, port and env var in the README and laptop-token-savings.md resolves against real code: installer flags (install.sh:52-65), abctl --endpoint, abctl tools scan --write|--days|--keep, transcripts at ~/.claude/projects, and ports 47600/47601. No command in either page fails.
  • Ports are consistent across the shell and the Go. local.go pins 47600/47601/47602/47604 and install.sh probes and prints the same three it needs. The health pin to 127.0.0.1:47604 is real, and the old ":9091" exposure was real.
  • health_addr is defaulted by every preset. presets.go's mode switch has no early returns, so setDefault(&cfg.Listener.HealthAddr, ":9091") runs unconditionally — including for unknown modes — and all three binaries call ApplyPreset before use. Kubernetes probes are genuinely unaffected.
  • The logging fix is right. slog.SetLogLoggerLevel(slog.LevelError) sits after SetDefault in runtimeutil.go, and every log.Fatal* in the proxy runs after InitLogging, so the port-clash case really does surface at ERROR now.
  • The --demo alias is clean. Separate flag registrations, no collision, --demo --ca-dir X still works, and the deprecation warning fires only when --local was not also passed.
  • The migration warning's condition is correct — it requires the stale dir to exist and --ca-dir to be unset, so passing --ca-dir explicitly produces no false warning.
  • tools scan --write genuinely refuses on zero observed calls, returns non-zero, still prints the proposal, and the new test is load-bearing: it asserts the exit code, the stderr reason, and that the config bytes are unchanged. Remove the guard and three assertions fail.
  • The install-demo.sh shim's security claim holds — it curl -os to a temp file and then sh "$tmp", so a truncated fetch cannot execute as a partial script.
  • The CI matrix additions are shaped like the existing ones and authbridge-cpex's exclusion is consistent with build.yaml building it as an image. .gitignore's cortex-ca/ is unanchored, so it does match a nested authbridge/cortex-ca/, and no tracked file is caught by the new rules.
  • checksums.txt filtering is correct — anchoring to end-of-line and matching only the two archives actually fetched avoids failing on unrelated future artifacts.

One pattern worth naming: this PR fixes a drifted copy of the lite tag list in release-binaries.yaml, which is the third of four copies. The fourth still drifts. That is the duplication I flagged on #850 producing its second incident in two weeks.

must-fix — this check can never pass on Linux, so stop_previous_cortex always bails at :147 and the previous instance is never stopped.

authbridge-proxy is 16 characters. Linux caps comm at TASK_COMM_LEN - 1 = 15, so ps -o comm= returns authbridge-prox, and the *authbridge-proxy* glob does not match it. I checked the arithmetic and ran the glob:

$ printf 'authbridge-proxy' | wc -c
16
$ printf 'authbridge-proxy' | cut -c1-15
authbridge-prox
$ case authbridge-prox in *authbridge-proxy*) echo MATCH;; *) echo 'NO MATCH';; esac
NO MATCH

On macOS ps -o comm= returns the full executable path (I get /bin/bash for my own shell), which does match ~/.local/bin/authbridge-proxy — which is exactly why testing this on a Mac would not surface it.

The consequence is commit 4's headline fix. On Linux, following the README and then the token-cost guide hits the second preflight loop and dies at :171 with port 47600 is already in use — the failure the function exists to prevent. The verification in the PR description covers the negative control ("a foreign listener holding the port and our pidfile pointing at it — left alone") but not the positive case on Linux.

args= is untruncated on both platforms and is what the pid was launched with:

name=$(ps -p "$pid" -o args= 2>/dev/null || true)

That keeps the check just as narrow — it still only kills a pid from our own pidfile whose command line names the proxy. Matching *authbridge-prox* would also work but reads like a typo and invites someone to "fix" it back.

must-fix~/.cortex/local does not exist. The code writes the config to ~/.cortex/config.yaml: writeBuiltinConfig uses filepath.Join(cortexDir, localConfigName) with localConfigName = "config.yaml" and cortexDir = ~/.cortex, and install.sh:312 reads back exactly "${CORTEX_DIR}/config.yaml". There is no local/ component anywhere in the code path.

This is the error whose entire job is to tell a lost user where the config is, so pointing at a path that never exists is the worst place for it to be wrong. It also lands because of the sibling problem: docs/tool-prune-plugin.md:50 now tells people to run abctl tools scan --write ~/.cortex/local/config.yaml, which fails here, and then this message hands them a second wrong path.

Should read writes config.yaml under ~/.cortex.

While in this function, the comment just above at :29-32 is now stale in the same way — "the demo anchors its config to the directory it was launched from, so a relative path resolves against the wrong place" was the justification for this whole error message, and it stopped being true when the default moved under $HOME. The hint at :42 (curl -s localhost:47602/config | grep ca_dir) is still correct; 47602 is the stats port.

must-fix — this command fails for everyone. The config is at ~/.cortex/config.yaml, not ~/.cortex/local/config.yaml (see local.go's localConfigName join, and install.sh:312).

A reader gets no config at /Users/…/.cortex/local/config.yaml from PatchConfig, whose own hint then points at ~/.cortex/local too, so there is no way to recover from inside the message. This is the one command the page exists to give, and filling the prune list is described two lines up as "the single act that enables it".

Dropping local/ fixes it. Worth grepping for the rest of the set at the same time — the same phantom path is in demos/session-budget/hitl-with-claude-code.md (six places) and in the PR description's rename table, which is where I think it came from: commit 3's table says ~/.cortex/demo/~/.cortex/local/, and commit 5 then consolidated to a single ~/.cortex/config.yaml without walking that table back.

must-fix — and this one is a regression rather than an incomplete rename: the text that was here before was correct, and it has been replaced with a path that does not exist.

This doc launches the proxy with an explicit config — -config ./authbridge/demos/session-budget/local/config-https.yaml — and that file sets ca_dir: "cortex-ca" (config-https.yaml:14), which is cwd-relative. So the CA really is at <repo-root>/cortex-ca/ca.crt. It is not under ~/.cortex at all, because this path never goes through --local's default. The pre-PR cwd-relative wording described that accurately.

Why this is the worst of the three: NODE_EXTRA_CA_CERTS pointing at a nonexistent file fails silently. Claude Code keeps working, every request tunnels opaquely, no plugin sees a body, nothing is pruned, and nothing looks broken — which is precisely the failure the PR description singles out as "the failure this feature is most likely to die of in someone else's hands." And :94 immediately below correctly insists the path must be absolute, so a reader has every reason to trust the literal string.

Five more in this file: :65 ("generates ~/.cortex/local/ca.crt on first launch"), :71/:72 (sample log lines showing ca_dir=/Users/you/.cortex/local, which the proxy would never print for this config), :171 (rm -rf ~/.cortex/local — cleans up nothing, and still carries the old "in the directory the proxy ran from" phrasing), and :184 ("--local has its own config at ~/.cortex/local/config.yaml").

Two ways to resolve, and they differ: restore cwd-relative cortex-ca/ca.crt for the -config config-https.yaml flow this page actually documents, or switch the page to plain --local and use ~/.cortex/ca/ca.crt. Only :184, which is genuinely about --local, takes the second form — its correct value is ~/.cortex/config.yaml.

suggestion — gating stop_previous_cortex behind port_in_use adds a failure mode without adding safety, and it is the reason the must-fix above degrades to a hard error rather than a no-op.

port_in_use returns "free" when neither lsof nor nc is installed (:102-104, deliberately). On a minimal container or a stripped VM that means: no port looks busy → stop_previous_cortex is never called → the new proxy starts anyway → bind conflict → the readiness loop sees the early exit and reports Cortex failed to start. The user is left with a dead install and a log, when a previous instance of ours was sitting right there in a pidfile we own.

The function is already the narrow, safe thing — pidfile we wrote, numeric pid, kill -0, process-name match, and it return 0s on anything unexpected. None of that needs a port probe to justify it, and it is a no-op when nothing is running. Calling it unconditionally before the preflight loop is both simpler and correct on hosts with no probe tool:

if [ "$MODE" = "local" ]; then
	stop_previous_cortex
	for p in ...; do ... done   # keep the preflight for foreign listeners
fi

Related, in the same block: the preflight probes 47600/47601/47602 but not the new health port 47604, so a clash there is the one case that still fails late — after the download, at log.Fatalf on the health listener — instead of in the friendly early check. Worth adding it to the loop now that it is a pinned port.

suggestion — two gaps behind "directories holding a key are now 0700 (was 0755)".

MkdirAll will not tighten an existing directory. If ~/.cortex already exists at 0755, this call succeeds and changes nothing. install.sh:266 is stricter than the Go here — it does mkdir -p "$CORTEX_DIR" && chmod 700 "$CORTEX_DIR", so the installer path is safe and a bare authbridge-proxy --local is not. An os.Chmod(cortexDir, 0o700) after this line closes it for one line and matches what the shell already does.

The directory that actually holds the key is still 0755. This function does not create caDir at all — the CA generator does, at authlib/tlsbridge/ca.go:138: os.MkdirAll(filepath.Dir(certPath), 0o755), unchanged by this PR. Under the default layout that is harmless, because ~/.cortex/ca sits inside a 0700 parent and nobody else can traverse in. But with --ca-dir /somewhere/else there is no 0700 parent, so a directory holding a signing key is world-readable — the key file itself stays 0600 (ca.go:147), so this is exposure of the listing, not the key. 0700 on ca.go:138 would make the claim true in both layouts and costs nothing: only the proxy reads that directory, and the ca.crt clients load is read by the same user.

suggestion — this fallback silently restores the bug the PR is fixing. When os.UserHomeDir() fails or returns empty, defaultCortexDir returns the bare relative "cortex-ca", which resolves against the process's working directory — so the CA and its private key land wherever the proxy was started, including a checkout of this repo. That is the exact scenario the commit-2 description opens with.

The new .gitignore rule keeps it out of a commit, which is a real backstop, but it does not stop the key being written to an arbitrary directory, and nothing tells the user it happened.

UserHomeDir only fails when $HOME is unset (a bare env -i, some systemd units, a scratch container), so failing loudly costs nothing anyone will hit by accident and turns a silent key-drop into an actionable message:

return "", fmt.Errorf("cannot determine home directory; pass --ca-dir explicitly")

If the fallback is deliberate, the comment at :25-26 ("the historical cwd-relative behaviour") is the place to say why keeping it is worth the key-in-cwd risk the rest of this file argues against — right now the two read as contradicting each other.

One knock-on: when this fires, cortexDir == "cortex-ca", so the migration warning in main.go reports ./cortex-ca as no longer used while now_using is cortex-ca/ca.

After this PR, ci.yaml, build.yaml and this file agree byte-for-byte and match both CLAUDE.mds; local-build-and-test.sh is the lone holdout, so the local "build the lite image and test it" path still compiles in a plugin the variant excludes — which is the same wrong artifact this PR is fixing, just produced on a laptop instead of in a release.

Worth noting because it is the second incident from this duplication in two weeks: #850 added this list as a fourth copy, and the next plugin will need a token in all four again. Since exclude_plugin_* fails open — a missing tag silently compiles the plugin in and only makes the binary bigger — a drifted copy produces no build error anywhere. A single lite-tags file that the two workflows and the script all read would make the next plugin a one-line change.

Also at local-build-and-test.sh:93: "so only jwt-validation + token-exchange compile" undercounts the lite set the same way authbridge/CLAUDE.md does — it is four (litellm-budget-track and static-inject are not excluded either).

nit--help prints nothing through the documented invocation. $0 is sh when the script is piped, so sed -n '2,30p' "$0" fails, 2>/dev/null swallows it, and the script exits 0 with no output. Confirmed:

$ cat script.sh | sh -s -- --help
$ echo 'echo "$0"' | sh -s -- --help
sh

The header at :16-17 specifically teaches sh -s -- as the way to pass flags, and --help is the flag most likely to be tried that way — by someone who wants to see the options before running an installer, which is a reasonable instinct for a curl | sh. It works via install-demo.sh, which downloads to a file first, so the deprecated path has better help than the current one.

A heredoc or a usage() function with the text inline is immune to how the script was invoked. Two smaller things if you keep sed: the 2,30p range stops before the Environment: block at :32-36, so the three env vars are undocumented in --help; and AUTHBRIDGE_SKIP_DOWNLOAD=1 sets version="(already installed)", which renders at :247 as Installed abctl and authbridge-proxy ((already installed)) to … — double parens, and "Installed" when nothing was.

Separately: DEMO_FORWARD_PORT/DEMO_SESSION_PORT/DEMO_STATS_PORT and the "Demo listener ports" comment at :88-93 are the only surviving "demo" naming in the new file, in the PR that drops "demo" from local installs everywhere else.

Answering "can I scan more than 30 days, or everything?": yes via --days N
with no upper bound, but reaching for all history meant --days 36500, which
is a magic number rather than an answer. --all says it directly.

Investigating the question turned up a genuinely misleading readout. The
summary reported tool-call lines counted BEFORE the timestamp filter, so it
printed the same figure for --days 1 and --days 36500 — 13826 either way on
my transcripts — while displaying "window N day(s)" right beside it. That
reads as a window that does nothing, and it is why I suspected a bug in the
filter before testing it. The filter was fine; the count was lying. Counted
after the filter, the same transcripts now report 5841 / 11551 / 13845 for
7 days / 30 days / all.

--days 0 is rejected rather than treated as "everything", and the error now
names --all. A zero-width window finds nothing used, so "tools you have not
called" becomes every tool in the table — the exact opposite of what someone
typing 0 intends. --all and --days together are rejected as ambiguous.

Summary says "all history (no window)" for an unbounded scan instead of
"window 0 day(s) since 0001-01-01".

Docs state which direction is safe, because it is not obvious: widening can
only find MORE tools in use, so it proposes FEWER for removal. --all is the
cautious end, the 30-day default the aggressive one.

Tests cover a 400-day-old call being excluded by the window and included by
AllTime, Lines tracking the window across three widths, and the summary not
leaking a zero date.

The installer prints `abctl tools scan --write <config>` with no --days, so
it applies the 30-day default — but the hint only said "proposes from your
own transcripts", which does not reveal that a window is being applied at
all, let alone which one.

That matters because the window decides what gets pruned, and the cautious
direction is counter-intuitive: a WIDER window finds more tools in use and
therefore proposes fewer for removal. Someone reading only the installer
output had no way to know either fact. It now names the 30 days and points
at --all for sparing anything ever called.

The cost page already stated both; this closes the gap for anyone following
the terminal rather than the doc.

All twelve findings verified against the code; all twelve were right.

**stop_previous_cortex never ran on Linux.** "authbridge-proxy" is 16
characters and Linux caps comm at TASK_COMM_LEN-1 = 15, so `ps -o comm=`
reports "authbridge-prox" and the `*authbridge-proxy*` glob never matched.
The function bailed every time — meaning commit 4's headline fix, following
the README and then the token-cost guide, still died on a bind conflict
there. macOS does not truncate, which is exactly why testing on a Mac
passed. Now matches a 15-character-safe prefix.

**It was also gated behind port_in_use**, which reports "free" when neither
lsof nor nc exists. On a minimal container that skipped the stop, the new
proxy hit the conflict anyway, and the user got a dead install with a
previous instance of ours sitting in a pidfile we own. Called
unconditionally now; it is already a no-op when nothing of ours is running.

**The preflight never checked 47604**, which local mode binds for health —
so an occupied port let the download finish and then killed the proxy
during startup.

**~/.cortex/local does not exist.** Eight references across three files
pointed at it. Commit 3 renamed demo/ -> local/, commit 5 consolidated to a
single ~/.cortex/config.yaml, and I never walked the commit-3 renames back.
Two of them were the worst possible places: docs/tool-prune-plugin.md gave
the one command that page exists for, and PatchConfig's error — whose whole
job is telling a lost user where the config is — pointed at the same
phantom directory, so there was no way to recover from inside the message.

**The session-budget doc was a regression, not an incomplete rename.** Its
text was correct before I touched it: that walkthrough passes -config
explicitly, and that config sets `ca_dir: "cortex-ca"` — cwd-relative,
never under ~/.cortex. I replaced accurate wording with a path that does
not exist, and NODE_EXTRA_CA_CERTS pointing at a missing file fails
silently: every request tunnels opaquely and nothing looks broken. Restored,
and it now says why this one is cwd-relative.

**Key-directory permissions did not hold up.** MkdirAll leaves an existing
directory's mode alone, so a ~/.cortex created earlier stayed 0755 under a
bare `authbridge-proxy --local` (install.sh chmods, the Go did not) — added
os.Chmod. And the directory that actually holds the signing key is created
by tlsbridge at 0755; harmless inside a 0700 parent, but --ca-dir elsewhere
has no private parent. Now 0700.

**The no-$HOME fallback silently restored the bug this PR opens with**,
writing the CA and its key into the working directory with nothing said.
UserHomeDir only fails when $HOME is unset, so it now fails loudly and
names --ca-dir.

**The lite tag list had a fourth copy** in local-build-and-test.sh, still
missing exclude_plugin_toolprune. Since a missing exclude_plugin_* tag
compiles the plugin IN and only changes binary size, drift produces no error
anywhere — second incident in two weeks. All four now read
cmd/authbridge-proxy/LITE_BUILD_TAGS, following the CPEX_FFI_VERSION
precedent; build.yaml resolves it in the step that already resolves cpex's.

Also: --help printed nothing through the documented `curl | sh -s --` pipe
($0 is "sh", so reading the script failed and 2>/dev/null hid it) — replaced
with a heredoc usage() that also covers the env vars the sed range missed;
"((already installed))" now reads once; cmd/README.md claimed every port is
a `listener.*` address when 9093 is `stats.stats_address`; and both POSIX
installers now say why they use `set -eu` rather than the repo's bash
`set -euo pipefail`.

Verified: the truncated, full and absolute forms of the process name all
match while python3/sleep do not; the stop fires end to end; lite builds and
tests from the shared tag file; all three consumer paths resolve; four
workflows parse; five modules and authlib clean; shellcheck clean on three
scripts.

- **The proxy won't start** — read `~/.cortex/proxy.log`; a port conflict is logged
at `ERROR`. Every listener is pinned to loopback on 47600–47604, so a clash
usually means Cortex is already running (`kill $(cat ~/.cortex/proxy.pid)`).

Do not kill an unvalidated PID.

A stale proxy.pid can contain a recycled PID. kill $(cat ~/.cortex/proxy.pid) can then terminate an unrelated process. Validate that the PID is numeric and that ps identifies authbridge-prox before calling kill, as stop_previous_cortex does.

Comment thread authbridge/install.sh Outdated
The instructions asked for three environment variables on every invocation.
Claude Code reads env vars from the `env` block of ~/.claude/settings.json,
so they belong there instead — set once, and `claude` is just `claude`.

That is not only shorter, it is more correct. Claude Code's supervisor is
one process shared by every terminal and inherits the environment of
whichever shell cold-started it, so an exported HTTPS_PROXY or CA path
reaches background agents when that shell happened to start the supervisor
and silently does not when a different one did. Its own network
documentation says to use settings for exactly this reason.

New `abctl claude-code enable | disable | status`, and install.sh grows
--claude-code to offer it during setup.

The merge is in Go rather than shell because the target file routinely holds
an API token in the same env block; shell JSON surgery there is not worth
attempting. It:

  - reads the proxy address and ca_dir from ~/.cortex/config.yaml, so the
    values cannot drift from the running proxy. Hardcoding 47600 would point
    Claude Code at nothing the moment someone edited their config.
  - writes only its three keys and leaves every other setting byte-identical,
    including ANTHROPIC_BASE_URL and any auth token
  - copies the file to settings.json.bak, then replaces it atomically —
    Claude Code watches and reloads it, so a half-written file would be read
  - refuses when HTTPS_PROXY is already set to something else, rather than
    breaking a corporate proxy silently
  - refuses to write over settings.json it cannot parse, instead of
    destroying keys it never read
  - is idempotent, so install.sh can run it on every invocation

install.sh delegates the prompt to abctl, which reads /dev/tty: stdin there
is the script itself under `curl ... | sh`, so reading stdin would consume
the script or see EOF and silently decline. With no controlling terminal it
says so and declines, which install.sh treats as skipped, not failed.

Being straight about test coverage: this tool session has no controlling
terminal, so I could not exercise the live prompt. confirm() is split into
the tty-opening half and confirmFrom(), and the tests cover the answer
parsing (y/Y/yes/YES apply; n, empty, EOF and anything ambiguous decline,
because the file holds tokens) plus the no-tty fallback path end to end. The
--yes path, the preservation property, the config-derived addresses, the
clobber and bad-JSON refusals, disable, and idempotency are all tested
against a settings.json shaped like a real one.

While enabled, Claude Code needs Cortex running — its requests go to the
proxy address. `abctl claude-code disable` is the off switch, and both the
command and the README say so.

The quickstart said "an AI agent" while every step was Claude Code —
install.sh --claude-code, `claude`, and a viewer showing its calls. Now the
heading says so: "Quick start — Claude Code on your laptop". One line at the
end covers other agents, which is the honest weight: the proxy is generic,
the wiring is not.

Also trimmed, 297 words to 151. What went was explanation nobody needs at
step 1: how --claude-code edits settings.json and what it leaves alone (the
command prints that before it acts, and `--help` has the rest), why settings
beat a shell export (a "why" for the curious, not a step), and the
--install-only aside.

Cost page opening got the same treatment, 1051 words to 892. The
window-choosing paragraph was five sentences to say "wider is safer".

Fixes an anchor the rename would have broken: session-budget's [qs] link
pointed at #quick-start-local-no-kubernetes. Both remaining links now
resolve against a real heading, checked by computing the GitHub slug.

…rong port

`abctl` with no flags demanded kubectl and opened a cluster picker, so the
laptop quickstart had to type --endpoint http://localhost:47601 every time.
It now connects to the Cortex on this machine when one is running.

The address is read from ~/.cortex/config.yaml rather than hardcoded, so it
follows a port someone changed. Only used when the session API actually
answers: a stale config from an install that is no longer running must not
steer someone away from the picker when they meant to work against a
cluster.

The [l] "connect to localhost" key had the same bug from the other end: it
was hardcoded to :9094, the in-cluster default, so on every laptop it
connected to the wrong port. It now uses the same resolved address, and the
footer shows which one — one accessor so the key, the footer and the empty-
state hint cannot disagree. With no local config it still says 9094, so
in-cluster behaviour is unchanged.

Testing this turned up a real bug in guidance I wrote earlier. The built-in
config did not pin transparent_proxy_addr, on the reasoning that --local
skips that listener. True — but the troubleshooting text tells people to
start that same file with `authbridge-proxy --config ~/.cortex/config.yaml`,
and --config does not skip it, so it bound ":8082" on every interface and
died on a clash with anything already there. Reproduced it, pinned the
address, and the config is now safe however it is launched. That is the
second time the "it is skipped in this mode" shortcut has cost something.

`--endpoint` still works and still wins; only the default changed.

Tests cover the port being read from config (including ":9094" and
"0.0.0.0:9094" needing a dialable host), no config meaning no local
endpoint, and the liveness probe rejecting a closed port and a 5xx. The TUI
itself needs a terminal this session does not have, so the [l] wiring is
covered by the existing pane tests rather than an interactive run.

All eight verified; all eight real.

**settings.json lost non-string env values.** envBlock read the block into
map[string]string and the result was assigned back over the whole block, so
`"env": {"DEBUG": true}` vanished — directly contradicting this command's own
help text. The fixture was all strings, so nothing caught it. Callers now
mutate the raw map[string]any in place; a test covers bool, number, null,
array and object entries through both enable and disable, and I confirmed it
fails against the old code before fixing it.

**The scan's refusal described a window that had not run.** With --all it
said "no tool calls at all in the last 30 day(s)" and advised widening with
"--days or --all" — a combination it rejects with exit 2. It formatted *days
while the scan used window. Reachable in exactly the fresh-install case the
guard exists for; same class as 655b71d, which is twice now that a message
has reported a value the code did not use.

**enable wrote NODE_EXTRA_CA_CERTS without checking the file exists.** That
is the silent-trust-anchor failure this PR keeps naming: requests keep
working, every one tunnels opaquely, nothing looks wrong. Enabling before
the first start is legitimate, so it still writes — but now says the file is
not there yet and what that will look like.

**The backup was overwritten on every write**, so one enable/disable round
trip replaced the pristine pre-Cortex settings.json with our own output. Its
whole value is being the version the user wrote. Written once now, never
refreshed.

**install.sh pre-created ca_dir** at the shell's umask before starting the
proxy, so tlsbridge's new 0700 never applied — MkdirAll does not tighten. The
same trap local.go needed an explicit Chmod for, one directory down. Fixed
by not creating it: the proxy makes it correctly.

**LITE_BUILD_TAGS had no format contract or guard.** An empty-but-present
file yielded TAGS="" and a silently full "lite" binary; a comment line would
have been concatenated into the tag list by `tr -d`. Both fail open, since Go
accepts unknown -tags silently. The file now documents its format and carries
comments, every one of the four readers strips them and refuses an empty
result, and I checked the tag set still produces a 22.8MB lite against a
47.5MB full.

**--all had no test** — fs.Bool("All", …) would have compiled and passed.
Covered now, along with the exit-2 on --all with --days, and the refusal
naming the right scope in both modes.

**The zero-evidence guard was binary**: one observed call cleared it and
still proposed removing nearly every known tool. Raising it to an arbitrary N
would block legitimate light users, so it warns instead, naming the count and
pointing at --all. Thin evidence is a property of the input, not an error.

The PR description is stale in the ways listed and is being rewritten
separately.

Do not use a truncated process name as process identity.

This pattern accepts any process whose Linux comm begins with authbridge-prox. If a stale pidfile points to a reused PID for authbridge-proxy-helper or another same-prefix process, the installer sends SIGTERM to that foreign process. This breaks the requirement to preserve foreign listeners. Compare an exact executable or command token before calling `kill.

Quote the executable and path arguments in the generated commands. When HOME contains spaces, the command at line 368 splits local_cfg, and the command at line 383 splits the path passed to cat. If BIN_DIR is not on PATH, abctl_cmd also splits. Emit "${abctl_cmd}" ... --write "${local_cfg}" and kill "$(cat "${pidfile}")" so users can copy these commands successfully.

Comment thread authbridge/install.sh Outdated
It was current on pricing — rossoctl#849 updated the glob patterns and per-million
units there — but two behaviors from this PR had not reached it.

The scan paragraph described neither window flag. `--days N` and `--all`
change what the command proposes, and which direction is safe is not
guessable from the names: a longer window finds more tools in use and so
proposes fewer for removal. It also omitted the refusal when no tool calls
were observed, which is the behavior a reader on a fresh machine will
actually hit.

And `remove` did not say an empty list is the off switch, which is now how
the local install ships — inert until a name is added.

Left the Direction column as Outbound. tool-prune does run on an inbound
chain (proven while exploring gateway mode), but that shape is not something
this PR ships guidance for, and widening the column would advertise it.

Substantial, unusually well-documented PR: 15 commits collapsing the Claude Code quickstart from nine commands and three env vars to two commands and none, plus the genuinely release-blocking abctl GOWORK=off build fix. The comments explain why rather than what, and several document bugs found by executing the instructions instead of reading them — the comm 15-char truncation making stop_previous_cortex a no-op on Linux, the backup that overwrote the pristine file on a second run, the filtered env copy that silently dropped non-string values. 24 new tests map closely onto the claimed behaviors.

One must-fix: the checksum verification in install.sh fails open when checksums.txt is missing an entry for one of the two archives, so an unverified binary can still be installed. Everything else is non-blocking.

Areas reviewed: Go (abctl, authlib, cmd/*), Shell (install.sh, local-build-and-test.sh), CI/GitHub Actions, Docs, YAML
Commits: 15, all signed-off (DCO passing)
CI status: passing (23 checks; Spellcheck and tidy skipped)
Agent/IDE config (.claude/.vscode): none touched

Things I checked that are correct:

  • LITE_BUILD_TAGS is consumed identically by all four call sites (ci.yaml, build.yaml, release-binaries.yaml, local-build-and-test.sh), each with the empty-list exit 1 guard — appropriate, since exclude_plugin_* fails open.
  • The --claude-code handoff delegates the JSON merge to abctl rather than editing a token-bearing file from shell, and /dev/tty for the prompt is right under curl | sh.
  • tlsbridge/ca.go 0700 plus the note that MkdirAll never tightens an existing dir, and install.sh deliberately not pre-creating ca_dir for that reason — those two are consistent.
  • --days 0 rejected in favour of an explicit --all is the safe direction (wider window ⇒ fewer removals).

must-fix — checksum verification fails open.

grep -E "(${abctl_tgz}|${proxy_tgz})\$" succeeds when it matches only one of the two archives. So if checksums.txt is missing an entry for one binary, this guard passes, sha_check verifies just the single listed file and exits 0, and the unverified binary is installed anyway a few lines below.

That's the one step in the script whose whole job is to not fail open. A truncated or partially-generated checksums.txt from a bad release build is the realistic trigger, and nothing downstream would notice.

Assert both entries are present, e.g.:

grep -E "(${abctl_tgz}|${proxy_tgz})\$" "${tmp}/checksums.txt" > "${tmp}/checksums.filtered" \
	|| die "no checksum entries for ${abctl_tgz} / ${proxy_tgz} in checksums.txt"
[ "$(wc -l < "${tmp}/checksums.filtered")" -eq 2 ] \
	|| die "checksums.txt is missing an entry for one of ${abctl_tgz} / ${proxy_tgz}"

or grep for each archive separately so a missing entry is attributable to a specific file.

suggestionstrings.Cut splits at the first colon, which mis-parses IPv6.

For a bind address like [::1]:47600 this yields host="[" and port=":1]:47600", so the value written into settings.json becomes a malformed http://[:1]:47600. The surrounding code clearly intends to handle IPv6 (the host == "::" wildcard check on line 120), so this isn't a case of IPv6 being out of scope.

net.SplitHostPort is the right tool — it understands the bracketed form and returns a real error on genuinely malformed input, which also lets you drop the hand-rolled ok check:

host, port, err := net.SplitHostPort(addr)
if err != nil {
	return nil, fmt.Errorf("listener.forward_proxy_addr %q is not host:port: %w", addr, err)
}

Note that the reassembly then needs net.JoinHostPort(host, port) rather than host + ":" + port, so an IPv6 literal keeps its brackets in the URL.

The shipped defaults are IPv4 loopback, so the happy path is unaffected — but this writes a broken value rather than reporting an error, and NODE_EXTRA_CA_CERTS/proxy misconfiguration is exactly the failure mode the rest of this file works hard to make loud.

suggestion — same first-colon strings.Cut issue as cmd_claudecode.go:116.

An IPv6 session_api_addr produces a malformed endpoint URL here too. The consequence is quieter than in cmd_claudecode.go — the probe just fails and abctl falls through to the cluster picker — but it's the same defect, and the silent fall-through makes it harder to diagnose than an error would be.

net.SplitHostPort (plus net.JoinHostPort when rebuilding) fixes both call sites; worth doing in one pass.

nithost == "::" is unreachable.

strings.Cut("::", ":") returns host="", port=":", so the host == "" test earlier in the same condition always matches first and the "::" arm never fires. Same dead branch at local_endpoint.go:44.

Harmless as-is (the wildcard still ends up rewritten to localhost via the empty-host case), but switching to net.SplitHostPort per the comment above makes this check meaningful again, since it returns "::" intact as the host.

**The checksum guard installed unverified binaries.** One `grep -E "(a|b)$"`
succeeds when it matches only ONE of the two archives, so a checksums.txt
missing an entry passed the guard, sha_check verified just the listed file
and exited 0, and the unverified binary was installed a few lines later.
Reproduced it: guard PASSED with 1 of 2 entries. That is the one step in the
script whose whole job is not to fail open, and a truncated or partly
generated release build is the realistic trigger. Now one grep per archive
so a miss names the file, plus a count assertion, and it aborts.

**strings.Cut mis-parsed IPv6 in two places.** It splits at the FIRST colon,
so "[::1]:47600" gave host="[" and port=":1]:47600". In cmd_claudecode.go
that wrote a malformed http://[:1]:47600 into settings.json — a broken value
rather than an error, in the file whose misconfiguration is the silent
failure the rest of that code works to make loud. In local_endpoint.go it
produced an endpoint that just fails to connect, after which abctl falls
silently through to the cluster picker. Both now use net.SplitHostPort and
net.JoinHostPort, so brackets survive into the URL and bad input errors.
That also makes the `host == "::"` branch reachable: with Cut it was dead,
because Cut("::") returns host="" and the earlier empty test always won.

**A JSON `null` settings root panicked.** It is valid JSON that unmarshals to
a nil map, and assigning into one aborts the process with "assignment to
entry in nil map". Confirmed, then fixed.

**A refusal and a failure shared exit code 1**, so the installer treated
"HTTPS_PROXY is already a corporate proxy" as "the user said no" and exited
0 with Claude Code unconfigured. Declining is now 3; the installer skips on
3 and dies on anything else. Verified both paths end to end.

**The probe accepted any status under 500.** A 404 from an unrelated service
holding the port counted as a live session API. Only 2xx now; the test
covers 404, 401 and 301 alongside 500.

**An unresponsive configured address still overrode `[l]`.** Passing it to
the TUI took away the in-cluster default, so a working port-forward on 9094
could not be reached with the one key that exists for it. Only passed when
the probe succeeded.

**stop_previous_cortex removed the pidfile after 5s** while the proxy allows
itself 15 (main.go:541), so a draining request could still hold the listener
and the next preflight would fail with the previous instance invisible. Waits
18s now, and if the process is still there it keeps the pidfile and says so
rather than continuing into a bind conflict.

**Docs and installer output told users to `kill $(cat proxy.pid)`** — a
stale pidfile can name a recycled pid. `pkill -f authbridge-proxy` instead:
nothing else on the machine has that name.

**Generated commands are quoted** so a $HOME with spaces still copy-pastes.

Rejecting one: CodeRabbit wants `set -euo pipefail` per the repo guideline.
pipefail is a bashism and the documented entry point is `curl ... | sh`, so
adding it would break the thing the script exists to do. The deviation is
commented in both installers. The guideline is wrong for a POSIX file, not
the file wrong for the guideline.

Three other open threads (comm truncation on Linux, MkdirAll not tightening,
--help through a pipe) were already fixed in 5f654ec and 1ab308f; the
threads are still anchored to lines that exist.

Keep kill "${proxy_pid}" for the installer’s current child PID, but do not document raw kill "$(cat ~/.cortex/proxy.pid)"; a recycled PID can target another process.

rossoctl#861 solves the same duplication — the exclude_plugin_* list copied into
ci.yaml, build.yaml, release-binaries.yaml and local-build-and-test.sh — and
solves it better. Its authbridge/scripts/lite-tags generator DERIVES the list
by parsing `//go:build !exclude_plugin_<name>` from plugins_*.go, with a
liteKeep allowlist for what stays. A newly added plugin is therefore excluded
from lite automatically.

LITE_BUILD_TAGS only fixed the four-copies symptom. It still had to be edited
by hand when a plugin was added, so it could drift from the set of plugins
that actually exist — which is the root cause. Two competing mechanisms would
be worse than either, so this removes ours.

Their generator's output is byte-identical to the file it replaces,
exclude_plugin_toolprune included, so rossoctl#861 independently carries the
local-build-and-test.sh fix this PR had made and wires the same four
consumers.

build.yaml, release-binaries.yaml and local-build-and-test.sh are back to
their upstream content, so this PR no longer touches them at all. ci.yaml
keeps only the unrelated change: abctl and authbridge-praxis added to the
build matrix, which is what caught the release-breaking go.sum gap.

Verified: with this, merging rossoctl#861 into this branch produces zero conflicts
(it was four before), the lite tag set still builds and tests, and ci.yaml
parses.

One dependency this creates, stated plainly: release-binaries.yaml on main
still omits exclude_plugin_toolprune, so until rossoctl#861 lands the published -lite
binary compiles tool-prune in. Harmless — bytes only, and it cannot satisfy
RequiresAny: [inference-parser] in that variant — but it is real, and
re-adding the one-line fix here would recreate the conflict.

Summary

Substantial, exceptionally well-documented PR (45 files, 15 commits) collapsing the Claude Code quickstart to two commands — and, importantly, fixing the release-blocking abctl GOWORK=off build break (the missing go.sum entry after #849's gjson import, plus the CI matrix gap that hid it by only covering authbridge-proxy/-envoy).

I checked the three previously-raised blockers against the current HEAD (last commit 389ebf7 @ 20:25; esnible's review @ 21:06 is after it):

Prior blocker Source Status at HEAD
comm 15-char truncation → Linux no-op huang195 ✅ Resolved — now matches the 15-char prefix *authbridge-prox* with a comment explaining the TASK_COMM_LEN truncation
Phantom ~/.cortex/local/… paths huang195 ✅ Resolved — no occurrence of .cortex/local anywhere in the diff; paths are ~/.cortex/config.yaml + ~/.cortex/ca/
Checksum verify fails open on partial checksums.txt esnible ❌ Still present — the one must-fix (inline below)

One thing worth calling out approvingly: LITE_BUILD_TAGS is now a single source consumed by all four call sites (ci.yaml, build.yaml, release-binaries.yaml, local-build-and-test.sh), each with an empty-list exit 1 guard, and it correctly carries exclude_plugin_toolprune as the 8th tag. That resolves the tag-list drift flagged on #850 and the --lite omission that compiled toolprune into two of four lite builds. Good fix, right shape. One non-blocking thought on it: because a single dropped exclude_plugin_* tag is silent (fails open to a bigger binary that still calls itself "lite"), the empty-list guard won't catch a one-tag regression — consider a small CI assertion that the resolved list contains each expected tag (or at least exclude_plugin_toolprune, given it just caused an incident). (Left in the body rather than inline because GitHub's PR file API doesn't expose that path for anchoring.)

One must-fix remains (esnible's, still live at HEAD): install.sh checksum verification fails open when checksums.txt covers only one of the two fetched archives. Keeping this at REQUEST_CHANGES until that's closed; everything else is non-blocking.

Areas reviewed: Shell (install.sh), Go (abctl claude-code/local, proxy/local, authlib), CI/GitHub Actions, Docs, security (checksums, key perms, loopback binding, PID-file signalling)
Commits: 15, all signed-off: yes
CI status: all passing (23 checks incl. the new abctl / authbridge-praxis Go CI matrix entries; Spellcheck/tidy skipped)

谋事在人 — the groundwork here is thorough; just the one gate left to close.

must-fix (confirming @esnible's blocker — still live against this HEAD). This grep -E "(${abctl_tgz}|${proxy_tgz})$" ... || die only dies when neither archive has a checksum line. If checksums.txt has an entry for one archive but not the other, grep matches the single line, the || die does not fire, and sha_check (shasum -a 256 -c) verifies only the file that is listed — -c never complains about an archive it was never asked to check. The unlisted archive then installs unverified.

Since you download exactly two archives, assert exactly two filtered entries before verifying:

grep -E "(${abctl_tgz}|${proxy_tgz})\$" "${tmp}/checksums.txt" > "${tmp}/checksums.filtered" \
  || die "no checksum entries for ${abctl_tgz} / ${proxy_tgz} in checksums.txt"
[ "$(wc -l < "${tmp}/checksums.filtered")" -eq 2 ] \
  || die "expected checksum entries for both archives, found $(wc -l < "${tmp}/checksums.filtered")"
( cd "$tmp" && sha_check checksums.filtered ) || die "checksum verification failed"

That closes the partial-coverage gap while keeping the end-anchored match that (correctly) ignores unrelated future artifacts.

`claude-code disable` removed every managed key it found, including one the
user had set themselves. CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC is the
realistic case: their "1" is byte-identical to ours, so nothing could tell
whose it was. Reproduced — present=false after an enable/disable round trip —
which is quietly taking away someone's configuration.

enable now records, once, what each managed key looked like beforehand, in
~/.cortex/claude-code-state.json. Outside ~/.claude deliberately: this
command's bookkeeping should not appear in a file Claude Code owns. disable
restores a recorded prior value and deletes only the keys that were absent,
and says which it put back.

Recorded on the FIRST enable only. A second enable overwriting it would
replace the user's original with our own value, losing it exactly when it is
needed. With no state file — enabled by an older abctl, or the record lost —
disable falls back to removing the keys, which is what it always did and is
better than leaving the proxy pointed at a Cortex someone is turning off.

Also fixes a test of mine that could not fail. The present-CA half of
TestClaudeCodeEnable_WarnsWhenCAMissing used strings.Replace with a count of
0, which replaces nothing, so the CA stayed missing and that branch was never
exercised. Split into two tests that each set up the state they assert on, and
mutation-checked the ownership test against the old behaviour.

Two other live threads are already closed at this HEAD and are anchored to
lines that still exist: esnible's `host == "::"` dead branch went away with
the switch to net.SplitHostPort in 79f2f57, and the checksum fail-open —
mrsabath's remaining must-fix — was fixed in 79f2f57 too, which postdates
the 389ebf7 they reviewed. The fix goes further than the suggestion: one grep
per archive so a miss names the file, plus the count assertion.

mrsabath's approving note on LITE_BUILD_TAGS no longer applies either — that
mechanism was withdrawn in d10039d in favour of rossoctl#861, whose generator derives
the list from the plugin files. Their non-blocking idea (assert each expected
tag is present, not just non-empty) belongs on rossoctl#861 now, and is a good one:
a single dropped tag still fails open.

Substantial, exceptionally well-documented PR (38 files) collapsing the Claude Code quickstart to two commands, and fixing the release-blocking abctl GOWORK=off build break — the missing go.sum after #849's gjson import, plus the CI-matrix gap that hid it (only authbridge-proxy/-envoy were covered). Adding abctl and authbridge-praxis to the matrix closes the gap.

I re-checked the three previously-raised blockers against current HEAD and all are resolved:

Prior blocker Source Status at HEAD
comm 15-char truncation → Linux no-op @huang195 ✅ matches the 15-char prefix *authbridge-prox*
Phantom ~/.cortex/local/… paths @huang195 ✅ gone; paths are ~/.cortex/config.yaml + ~/.cortex/ca/
Checksum verify fails open @esnible / @mrsabath ✅ fixed in 79f2f575 — one `grep …

The newest commit's claude-code enable/disable/status state bookkeeping (record-on-first-enable, restore-on-disable) is sound and well-tested — JSON round-trips preserve unknown and non-string keys, the null root is handled, and the writes are atomic (temp + rename). One non-blocking suggestion inline on hardening its corrupt-state path. IPv6/SplitHostPort handling, loopback pinning, and the --all / --days 0 / zero-evidence scan guards are all correct.

Areas reviewed: Go (abctl claude-code/tools/local_endpoint, proxy local.go, authlib config/runtimeutil/tlsbridge), Shell (install.sh), CI/GitHub Actions, Docs, security (checksums, 0700/0600 perms, loopback binding, PID signalling, token-file atomicity)
Commits: 18, all signed-off: yes (DCO passing)
CI status: all passing (22 checks incl. the new abctl/authbridge-praxis Go CI; Spellcheck/tidy skipped)

谋事在人、成事在天 — the groundwork here was the hard part, and it's thorough. The one gate I'd left is now closed.

suggestionreadState returns nil for both an absent state file and a present-but-unparseable one (the err != nil and st.Prior == nil branches collapse together), and disable treats nil as "no ownership record" → falls back to delete(raw, k) for every managed key.

That silently re-opens the exact data loss the state file was introduced to prevent: if ~/.cortex/claude-code-state.json is truncated or corrupted (partial write, disk-full, hand-edit), a disable deletes a CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 the user set themselves before enabling — with no warning, because a corrupt record is indistinguishable from an old-abctl/no-record install.

Consider distinguishing the two: keep the silent fallback for os.IsNotExist, but on a genuine read/parse error emit a warning (or refuse to delete) before falling through. Cheap, and it makes the one lossy path loud rather than silent. Not blocking.

readState returned nil for both an absent record and a present-but-unreadable
one, and disable treats nil as "enabled by an older abctl" and falls back to
deleting every managed key. So a truncated or hand-mangled
claude-code-state.json re-opened exactly the data loss the record was added to
prevent, and did it silently — a corrupt record was indistinguishable from no
record. Reproduced: the user's own
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 gone, stderr empty.

readState now returns (nil, nil) only for a genuinely absent file and an error
for anything it found but could not trust. Absent stays silent, because that
is the normal older-install path and a warning on every disable would train
people to ignore it. A read or parse failure warns, names the file and the
parse error, and says the value is not recoverable from there — then proceeds,
because the user asked for this off.

writeState also refuses to overwrite an unreadable record: if it can be
repaired by hand it is still the only copy of what the user had.

Mutation-checked the warning test by forcing the error to nil, which makes it
fail as it should.

That was mrsabath's suggestion on the approving review, and it was right.
Their other note — that the empty-list guard on the lite tag list cannot catch
a single dropped tag, since exclude_plugin_* fails open — now belongs to rossoctl#861,
which owns that list; worth raising there.

Two threads still shown as unresolved are already closed at this HEAD, both
anchored to lines that moved: esnible's `host == "::"` dead branch went away
with net.SplitHostPort in 79f2f57 (the code at the cited line is now the
SplitHostPort call), and the checksum fail-open was fixed there too.
