6a2f7fec04 docs: record the read-only Defenseurs mounts (#36)
All checks were successful
CI / verification (pull_request) Successful in 20s
Both Defenseurs bind mounts are `:ro` since 2026-09-30, set as a suffix
on the Coolify destination path; the reports Directory Mount was recreated
as a Volume Mount with a Source Path to take it. CLAUDE.md, README.md and
.env.example now describe the two layers (mount mode and Unix
permissions), the three checks to run after a redeploy, and the Coolify
gotchas met on the way.

523d90bf7c fix(hosts): require 3 loadAvg values and sweep orphan temp files (#25)
All checks were successful
CI / verification (pull_request) Successful in 21s
CI / verification (push) Successful in 20s
Follow-ups from the review of the workstation monitoring stack (#18-#23):

- loadAvg must hold exactly 3 finite numbers (1/5/15-min averages). The
  admin card joins them, so a shorter array rendered a partial line and a
  longer one was silently truncated; both are now a 400, and a stored
  snapshot off that format degrades to neverSeen on read.
- sweepStaleTempFiles() runs at startup, before listen, and removes the
  `.<id>.<pid>.<ms>.tmp` files a process killed mid-write leaves behind,
  once older than an hour. Exact name format only, regular files only
  (lstat), best effort: a missing HOSTS_DIR stays silent, other failures
  are logged and never stop the server.
- Document that cleanString keeps control characters on purpose (safety
  rests on the consumer escaping at render time), and that frozenRequest
  does not freeze `new Date()`, which stamps receivedAt on POST.

Fixes #25

156ca818ca ci: pin the review follow-ups of the CI workflow (#33)
All checks were successful
CI / verification (pull_request) Successful in 19s
CI / verification (push) Successful in 20s
- Forbid `continue-on-error` in ci.yml: that mutation left every test green,
  and a failing step would turn the commit status green in silence.
- boot-from-copy.sh refuses a port already held by something else (any curl
  exit other than 7). Without it, the wait loop could reach the neighbour and
  assert on a server it never started — the new test reproduces exactly that
  when the check is removed.
- Pin every require of the COPY'd runtime modules at column 0, with no
  dynamic import: the boot check only calls /health, so it only proves the
  modules loaded at startup.

4e7879da6c ci: add a Forgejo Actions workflow with a boot-from-COPY check (#24)
All checks were successful
CI / verification (pull_request) Successful in 21s
CI / verification (push) Successful in 19s
Nothing verified this repository until now. The workflow runs on every pull
request (no branches filter, so intermediate stack links get a status) and on
pushes to main, in node:22-alpine, the Dockerfile's own base: npm ci, npm test,
the socket-level pass, then scripts/boot-from-copy.sh.

The script stands in for a docker build, which would need the Docker socket in
the instance-scoped runner and so root on the production VPS for every
workflow. It starts the CMD from the COPY sources alone and fails on the
MODULE_NOT_FOUND that #11 had to fix by hand. __tests__/ci.test.js pins the
workflow and what the script assumes of the Dockerfile.

f006a1c05e test(auth): pin the single space after the Bearer scheme
Second review of #30: `startsWith("Bearer")` followed by slice(7) would
accept any byte as the separator (`Bearer\t<token>`, `BearerX<token>`) and
the suite stayed green. Two MALFORMED cases now reject both; the mutation
turns them red.

5074f95d0a test(auth): guard tokenMatches itself and close the pin's blind spots
Review of #30 found four mutations that left the suite green: an early
success return for the read kind, a reversed `want === header` comparison,
and tokenMatches() reduced to `===` or to raw strings behind a length check
(the GHSA-376v-xgjx-7mfr shape).

Behavioural guard: a spy on crypto.timingSafeEqual, set before a fresh
require of index.js, requires every request (6 read routes, short and
same-length wrong tokens, the right token, the ingest route) to compare two
32-byte digests. Source pins now also allowlist every equality operator in
checkAuth() (both operand orders), require a single `return null`, and check
that tokenMatches() hashes both sides without a length test.

All seven mutations (the reviewer's four, the original three) now turn
13-15 tests red. CLAUDE.md no longer claims the pin covers the helper.

f70a7e928f fix(auth): compare HEALTH_TOKEN in constant time via tokenMatches
The read path still compared the bearer with `header === \`Bearer ${token}\``,
which stops at the first differing byte and leaks the token's length and
prefix through response time. checkAuth() now has a single comparison for
both token kinds: `Bearer ` scheme check, then tokenMatches() (SHA-256
digests, then timingSafeEqual, so lengths are always equal). Only the
expected token varies.

Semantics are unchanged: exact match, case-sensitive scheme. Every existing
auth test passes untouched.

Tests: near-miss tokens (prefix, suffix, double space) on all six read
routes, an empty-token assertion on the helper, and a source pin that
forbids direct equality against a Bearer string and requires exactly one
tokenMatches() call in checkAuth(). A timing test would be flaky, so the pin
is the regression guard: three mutations back to direct comparison each
turn it red.

7c14e581cb test(defenseurs): cover GET /defenseurs/state in the socket-level pass
Four cases on top of the 41 from #26: the file served byte for byte
(non-canonical fixture, compared with cmp so the trailing newline counts),
no_data when absent, 401 without a token and 401 with the ingest token.

a5d1bcdedb feat(defenseurs): serve the Sergent's findings state at GET /defenseurs/state
The Sergent now persists per-finding state (firstSeen, unverified, 30-day
history) in findings-state.json next to status.json. The admin dashboard
needs it for the drill-down, since it is the only source carrying a
finding's age.

- New read route GET /defenseurs/state, path from
  DEFENSEURS_FINDINGS_STATE_PATH (default /data/defenseurs/findings-state.json),
  already covered by the /data/defenseurs mount.
- Extract serveJsonFile() so /defenseurs and /defenseurs/state share one
  contract: raw content, or 200 {status:"no_data"} on any read error.
- Tests: new state.test.js (byte-identical body, no_data, path isolation,
  401 x3, 404 on POST) and the route added to the auth.test.js matrix.
- Docs: README and CLAUDE.md endpoint, config and mount sections; the README
  mount list now matches the real /data/defenseurs directory mount.

50a829beb3 test(hosts): extend the socket-level pass to the two workstation routes
test-curl.sh predates vitest and still claimed to be the authoritative suite
for one endpoint. It is now the socket-level pass, and its header says so:
vitest covers the logic, this script covers what only a real client and a
real TCP connection can show.

Twenty-four cases for POST /hosts/<id> and GET /hosts, chosen for what they
prove rather than for coverage: the 413 answered before the connection is
cut, the two tokens refusing each other's routes in both directions, 401
landing ahead of 403 so an unauthenticated caller cannot probe the allowlist,
the route regex turning a malformed id and a traversal attempt into 404
before any handler runs, and the ingest-persist-read round trip closing on a
GET that shows the pushed hostname online.

Two cases needed care to be worth anything:

The hostile payload splices "__proto__" into the JSON as text. Written as
__proto__: in an object literal it would set the prototype and JSON.stringify
would emit nothing, leaving the case asserting against a payload that never
carried the key. It now checks the response and the persisted file, whose key
set must be exactly the whitelist.

The 413 case runs under set -e while the server destroys the socket right
after flushing the response, so curl can exit 55/56 having already read the
status line. Every probe goes through an http_code helper that absorbs that;
a curl which truly got nothing reports 000, which fails the case rather than
passing it quietly. -H "Expect:" also suppresses the 100-continue handshake,
which otherwise changes which side notices the reset first.

The fail-closed 503 needs a server booted without HOSTS_INGEST_TOKEN, so the
script now runs a second instance on 3098 for it, and confirms reads still
answer 200 there — the two tokens are independent, including in absence.

The EXIT trap dereferenced an unset SERVER_PID under set -u, which made it
error out instead of cleaning up when anything failed before the boot. Both
PIDs are initialised and the kills guarded.

CLAUDE.md: the vitest count was stale (244 -> 251, auth.test.js 19 -> 26) and
test-curl.sh was undocumented.

e24f5b6f00 feat(agent): push workstation metrics to /hosts/<id> from cron
Zero-dependency local agent: collect one snapshot through the shared
metrics.js, POST it once to /hosts/<id>, exit. Cron runs it every five
minutes. Nothing is queued and nothing is replayed — a heartbeat from five
minutes ago describes a machine that no longer exists, so a failed push is
logged and dropped rather than spooled.

run-push.sh sources ~/.config/maximus-host-agent.env (mode 600), refuses to
start when HOSTS_API_URL, HOSTS_INGEST_TOKEN or HOST_ID is missing, and never
enables shell tracing: the script is meant to be piped into `logger`, where
`set -x` would echo the ingest token into /var/log/syslog and journald for
good. Same reason the failure path reports only err.code and the HTTP status —
never an error object, request options, headers, or a response body. The cost
is accepted: a 400 says the payload was rejected, not why.

50 tests, including two that spawn the real process against a failing server
and scan its actual stdout and stderr for any five-character fragment of the
token. The payload is pinned against the server's own sanitizeSnapshot(), and
one case pushes a real collectMetrics() snapshot through the real ingestion
handler, so a drift between agent and server turns a test red instead of
producing a 400 at 3 a.m. on the ThinkPad.

agent/ stays out of the Docker image: the COPY line is untouched, and a test
pins that it copies files one by one and never names the directory.

Installing on a workstation — frozen copy, env file, crontab line, dry run,
and why two machines must never share a HOST_ID — is documented in
agent/README.md. The install itself belongs to the commissioning issue.

fedb1c81dc feat: ingest and serve workstation snapshots (POST /hosts/<id>, GET /hosts)
Open the API's first write surface. Workstations push their CPU / memory /
disk snapshot, the admin dashboard reads it back with a server-computed
freshness.

Routing moves from an exact path list to a descriptor table, keeping ONE
authentication checkpoint:

  resolveRoute()  -> no match means an immediate 404, deny by default
  checkAuth()     -> the single gate; only the expected token varies per
                     descriptor (HEALTH_TOKEN for reads, HOSTS_INGEST_TOKEN
                     for ingestion)
  dispatch

The routing-before-auth ordering is preserved on purpose: an unknown path or
a wrong method still answers 404, never 401, exactly as before. The two
`404 (not 401)` tests added in #12 pin that ordering and still pass.

Security controls on the new write path:

- The route regex ^/hosts/([a-z0-9][a-z0-9-]{0,31})$, POST-only, IS the path
  traversal control. URL() normalises /hosts/../../etc/passwd to /etc/passwd
  and encoded traversals fail the match, so every hostile id lands on 404.
  403 is reserved for well-formed ids outside the allowlist.
- 401 wins over 403, so an unauthenticated caller cannot probe the allowlist.
- tokenMatches() compares SHA-256 digests with timingSafeEqual. Scoped to the
  ingestion path only; realigning HEALTH_TOKEN touches every read route in
  production and is tracked separately.
- Body capped at 4 KiB by counting received bytes, never Content-Length:
  a client can lie in the header and chunked encoding omits it. Past the cap,
  413 then req.destroy() once the response has flushed.
- The persisted object is rebuilt field by field from a whitelist — finite
  numbers, strings capped at 128 chars, everything else dropped — because the
  file is read back by GET /hosts and ends up in the admin React tree. The
  read path re-runs the same whitelist: the bind-mount is writable, so the
  file on disk earns no more trust than the payload did.
- Snapshots are written to a temp file in the same directory then renamed, so
  a concurrent GET /hosts can never observe a truncated JSON.
- HOSTS_ALLOWED_IDS entries are validated at startup with the same regex;
  rejects are logged and dropped rather than becoming file paths.
- Every 401/403 is logged with X-Real-IP, the host id and the reason. Log
  values are filtered to printable ASCII so a crafted header cannot forge
  extra log lines.
- receivedAt is stamped by the server on arrival; a client-supplied timestamp
  is discarded by the whitelist. online = ageSeconds <= HOSTS_STALE_SECONDS.

Runtime stays zero-dependency — node:crypto is a builtin and no new module
file was added, so the Dockerfile's explicit COPY list is unchanged.

Tests: 61 (39 existing untouched + 22 new). __tests__/hosts.test.js is smoke
coverage of the decisions that would be silent to regress; the exhaustive
matrix is issue #14.

Docs: .env.example gains HOSTS_DIR / HOSTS_ALLOWED_IDS / HOSTS_INGEST_TOKEN /
HOSTS_STALE_SECONDS; CLAUDE.md and README.md document the endpoints, the
routing/auth ordering and the config. The CLAUDE.md "read-only" gotcha is
corrected — the API now writes, and HOSTS_DIR must be writable by uid 1000.

79cb813767 refactor: extract CPU/RAM/disk collection into metrics.js
Move readProcStat, getCpuPercent, getDisk and the cpu/memory/disk payload
assembly out of index.js into a standalone metrics.js, so the upcoming
local workstation agent can reuse the same collection code. No behaviour
change: /health returns the exact same fields, in the same order.

Notes:
- collectMetrics() returns the { cpu, memory, disk } slice; getHealth()
  spreads it, keeping the JSON key order the admin dashboard relies on.
- getHealth() keeps Promise.all([collectMetrics(), getLogtoHealth()]).
  The 500ms CPU sample and the 3s Logto check are deliberately concurrent;
  serializing them would push the p99 of /health to ~3.5s.
- collectMetrics() awaits the CPU sample as its only await, so callers
  running it inside a Promise.all keep their concurrency.
- Dockerfile COPY lists files one by one, so metrics.js had to be added
  there or the container would crash on MODULE_NOT_FOUND at startup.
- New __tests__/health.test.js: metrics.js exports, field-for-field
  payload shape, and a latency guard (<1.5s with a 1200ms stubbed Logto).
  Verified by mutation: serializing the two calls fails the latency test
  at ~1743ms while the field comparison still passes.
- Runtime stays 0-dependency; the 14 existing tests are untouched.

e88a044711 feat(defenseurs): add GET /defenseurs/findings?project=X route
Drill-down endpoint exposing detailed findings per project. Resolves the
HTTP gap for the Vercel admin dashboard, which cannot SSH/Tailscale to
the VPS, plus a future portable /analyse-vulnerabilite skill.

- Project -> agent lookup via /data/defenseurs/agents-map.json (Sergent snapshot)
- findLatestReportForAgent scans REPORTS_DIR + REPORTS_DIR/archive (post-07:30 UTC rotation)
- Filters: category exact match, severity threshold inclusive upward
- Asymmetric severity rule: default hides LOW+INFO; ?severity=LOW returns
  LOW+MEDIUM+HIGH+CRITICAL but still hides INFO; INFO opt-in via explicit param
- Distinguishes "report present + scan clean" (no status field) from
  "no report at all" ({findings:[], status:"no_data"})
- Bootstraps vitest (devDep; runtime stays 0-dep), 14 tests covering auth,
  validation, filters, asymmetry, mtime selection, error paths
- Refactor: export handler so tests can spin up ephemeral servers; server.listen
  guarded by require.main === module

6eda076a25 feat(reports): add GET /reports/scans endpoint for defenseur-auto
Replaces the SSH/rsync canal between Max's workstation cron and the VPS
for fetching defenseur scan reports. The defenseur-auto orchestrator now
pulls reports/defenseur-X_<date>*.json over HTTPS, reusing HEALTH_TOKEN.

The handler mirrors the style of index.js (HTTP native, no framework),
includes the same isScanReport guard as defenseurs/src/report.ts (filters
out defenseur-auto_*.json run reports), and validates the date param
against /^\d{4}-\d{2}-\d{2}$/ to short-circuit path traversal before any
filesystem access.

Validated by test-curl.sh — 11 cases covering auth, validation, date
filter, isScanReport filter, sort order, GET-only and 404 paths.

- Configurable via LOGTO_HEALTH_URL env (default: auth.lacompagniemaximus.com
  OIDC discovery endpoint)
- 3s timeout via AbortController; /health stays HTTP 200 even if Logto is down
- getCpuPercent converted to async (setTimeout-based delay) so the 500ms CPU
  sample and the Logto fetch run concurrently via Promise.all; total latency
  stays max(500ms, <=3000ms) instead of the sum
- Commit project CLAUDE.md (previously untracked) with the new field documented
