The demo itself is clean — I found no must-fix in the 538 lines of genuinely new content, and several of its more surprising claims hold up under checking. The block is entirely about what else is in the diff.
This PR carries #852 verbatim. Its first two commits are 58ccafb and 85cf776 — the same SHAs as #852 — and eight of the nine lineage-attach/ files are byte-identical to that branch's HEAD; the ninth differs only by a two-line cross-link to this demo. So 1541 of 2082 lines are already under review, and the six must-fixes I filed on #852 today are all present here unaddressed. That is the only reason for the verdict.
Worth rebasing onto feat/lineage-attach-kit rather than main: the diff would then show the demo alone. As it stands both PRs add the same nine paths, and demos/README.md gains one row in #852 and two here, so #852 merging first leaves an add/add conflict.
Verified rather than assumed, since a reader would reasonably doubt some of it:
- The
8335claim is correct, and non-obviously so.charts/rossoctl-deps/values.yamlshowshttp: endpoint: 0.0.0.0:4318, which looks like it contradicts you — butcharts/rossoctl-deps/templates/otel-collector.yaml:62passesreceivers::otlp::protocols::http::endpoint=0.0.0.0:8335, relocating the receiver. The Service still exposes 4318 with nothing behind it, so "8335, not 4318" is exactly right. k8s/weather.yaml's header comment checks out on both counts: the stockweather-agent/k8s/weather-service-advanced.yaml:40does carryrossoctl.io/outbound-ports-exclude: "11434", which you deliberately drop so the LLM hop is visible, and that manifest uses:latest+IfNotPresentidentically — so the image tags here match the sibling convention rather than diverging from it.- File modes are right:
ask.shandshow-trace.pyare 755, while the kit's sourced library and installed hook are correctly 644. - All three deep links resolve — both
RECIPE.mdsection anchors andREADME.md#troubleshootingmatch their headings exactly. - The arithmetic is internally consistent end to end: 1 A2A + 16 MCP + 2 LLM + 16 tool-inbound = 35 exchanges = 70 spans; 1 wire + 34 tracestate = 35; 1 entry + 18 app calls = 19 traces.
- Manifest hygiene is solid: pod- and container-level securityContext,
seccompProfile: RuntimeDefault, requests and limits on both containers, readiness probes, Service selectors matching pod labels, namespace explicit on every object.ask.shis strict-mode and fully quoted, pinscurlimages/curl:8.11.1, and emits a valid W3C traceparent.
One thing the demo does that the kit's own docs do not: step 2 passes NAMESPACE=team1 explicitly. That is the right habit, and it is also why this demo never trips #852's undocumented-team1-default finding. Similarly, weather.yaml declares no initContainers and no volume named envoy-config, so the demo path happens to avoid two of #852's must-fixes rather than exercising them — worth knowing, because a green demo run is not evidence those are fixed.
Areas reviewed: Python, Shell, K8s manifests, YAML, docs, security. 3 commits, all signed off, no Co-Authored-By. CI 20/20 green, Spellcheck skipped. No .claude/ or .vscode/ changes. Note this is still a draft PR, labelled ready-for-ai-review.

must-fix — this file, and seven of the eight others under lineage-attach/, are byte-identical to #852's HEAD (the ninth, README.md, differs only by a two-line cross-link to this demo). So every finding from the #852 review applies here unchanged, including its six must-fixes:
- this line — strategic merge prepends, so
proxy-initlands ahead of the target's own initContainers while its egress redirect outlives it; :273— a pre-existingenvoy-configvolume is silently repointed and itsitemsreplaced wholesale;:104—NAMESPACEdefaults toteam1, documented nowhere, and the kit README's kustomize example omits it;:61— "boots without the plugin" is wrong;plugins.Buildfails closed on an unknown name;build-otel-shim.sh:77—VENV_PYTHON, read from the base image's ownVIRTUAL_ENV, reaches two unquoted shell-formRUNlines;sidecar-patch.sh:157— the printedrollout undo --to-revisionrestores the whole pod template, so it reverts changes the owner made after the attach.
I am not re-filing them inline here — that would fragment the discussion across two PRs. Fixing them on feat/lineage-attach-kit and rebasing this branch onto it resolves both the findings and the duplication in one move.
Relevant to this demo specifically: k8s/weather.yaml declares no initContainers and no volume named envoy-config, and the demo's prerequisites pin a plugin-carrying SIDECAR_IMAGE, so the walk-through sidesteps must-fixes 1, 2 and 4 rather than exercising them. A clean demo run is therefore not evidence that those are addressed.

suggestion — check=True with capture_output=True makes the likeliest failure the least legible one. If deploy/otel-collector is absent from the namespace, or the user lacks pods/log in rossoctl-system, or the collector was renamed, this raises CalledProcessError and prints a Python traceback — with kubectl's actual message locked inside e.stderr where the user never sees it.
This is the demo's diagnostic tool, so it fails worst exactly when someone is already lost. A try/except CalledProcessError that prints e.stderr.strip() and returns 1 would match the clean handling already at :94-96 for the no-spans case.

There was a problem hiding this comment.
suggestion — the else "" fallback silently widens the stray-trace window. An empty string sorts before any timestamp, so one span block without a parseable Start time makes rows[0][0] empty, and stray_outbound_traces' first <= start.group(1) <= last test at :48 then admits everything from the start of the log rather than only what overlapped this trace.
That matters more here than it would elsewhere: the stray count is the number the README's headline result rests on (18 in step 3, 0 in step 5). A widened window would inflate it and misreport the demo's central claim as still-fragmented. Either skip blocks with no parseable start time, or compute the window from the non-empty timestamps only.

suggestion — ollama is not a secret, so this is fine as written; the concern is the path the comment two lines up invites. Once a user follows OpenAI: https://api.openai.com/v1, this key becomes a real credential sitting in a ConfigMap — visible to anything with get configmaps in team1 and to every kubectl describe of it.
Worth a half-line saying a real key belongs in a Secret referenced via envFrom.secretRef, since envFrom at :74-76 already takes that shape and the change is mechanical.

There was a problem hiding this comment.
suggestion — worth stating where the captured content lands. With CAPTURE_IO=true the spans carry the question, the prompts and the tool arguments, and the stock collector's exporter is debug — so all of it is written to the collector's pod log, readable by anyone with kubectl logs in rossoctl-system, and it stays there for the log's lifetime.
That is the right choice for this demo and the trade-off is already half-stated ("the demo's choice, not the kit's default"). But the demo is the artefact people copy into their own clusters, and #761 gates capture_io off by default precisely on this. One clause — demo only, user content goes to the collector's log — carries it.

nit — step 2 tells the reader to "Keep the back-out lines; step 6 uses them" (:70), but step 6 hardcodes --to-revision=1 and never uses them. That is correct arithmetic for this demo, since step 1 created both Deployments, and the reasoning at :152-155 for why the agent needs an explicit revision rather than a bare undo is right. It just makes the earlier instruction dead — either substitute the printed values here, or drop the ask at :70.

nit — the usage line omits --namespace, which is implemented at :85 with a rossoctl-system default, and is the flag someone reaches for first when the collector lives elsewhere. The exit codes are also worth a line while you are here: 0 for the good shape, 1 for no spans, 2 for fragmented — README.md:171 documents only that exit 0 means one root, and the 1-vs-2 distinction is the useful part for scripting.

nit — the host-tool line is right and closes a gap the kit's own prerequisites still have, but the permissions are unstated: ask.sh needs create pods in team1 (it runs a curl pod rather than port-forwarding), show-trace.py needs get pods/log in rossoctl-system, and steps 2, 4 and 6 need patch deployments plus create/delete configmaps in team1. All free on a kind cluster where the operator is admin, which is the documented target — so this is only for the reader running it against something more restricted.

Correcting my earlier review on this PR. I said the demo content itself had no must-fix. That was wrong — a deeper pass over the demo's own files against the kit turned up two, and both would stop a reader following the walk-through verbatim. The verdict does not change, but the reason it stands now includes the demo and not only #852's inherited findings.
Both are cheap to fix, and neither affects show-trace.py's verdict logic, which remains sound: it filters on lineage.role, so the pass criterion is unaffected by either problem.
One more thing worth stating since it cuts the other way: I re-confirmed that the collector port advice is right. charts/rossoctl-deps/templates/otel-collector.yaml:62 overrides the OTLP/HTTP receiver to 8335, so "8335, not 4318" is correct even though the Service still exposes a dead 4318, and the plugin's own default of 4317 (attach-lineage.sh:122) is a third port that is also correct. That is three ports in play, two of them right for different reasons — a half-sentence in the README noting the plugin uses 4317 while the app uses 8335 would stop a reader "fixing" one to match the other.

must-fix — KIT is only ever stated as inline prose here ("Run everything from this directory. KIT=../../lineage-attach."), never as an assignment in a copyable block. But step 2 at :55 is a copyable block that depends on it:
for d in weather-tool weather-service; do NAMESPACE=team1 DEPLOY=$d CAPTURE_IO=true $KIT/sidecar-patch.sh; doneWith KIT unset that expands to /sidecar-patch.sh, so the loop fails twice with No such file or directory and nothing is applied. Step 2 is the demo's central action, and the prerequisites already have a code block at :26-28 for the SIDECAR_IMAGE export — adding export KIT=../../lineage-attach there fixes it in one line.
Everything else about that invocation is correct: sidecar-patch.sh:57 needs only DEPLOY, defaults NAMESPACE and SELF_ID, and CAPTURE_IO reaches the generator through the environment via sidecar-patch.sh:136-137 → attach-lineage.sh:123-127.

There was a problem hiding this comment.
must-fix — the tool container never receives an OTLP endpoint, so two claims in the README describe things that cannot happen.
This env list is the whole of it — PORT, HOST, UV_NO_CACHE — and step 4 (README.md:110) sets OTEL_EXPORTER_OTLP_ENDPOINT on deploy/weather-service only. With no endpoint the SDK default is localhost:4318, so nothing leaves the pod. Therefore:
README.md:121-122— "its other outbound — its own OTLP export to the collector — is on the plugin's defaultbypass_hostslist, so capture is all it needs" — reasons about an export that does not occur.README.md:145-147— "the tool'stools/listandtools/call… 82 of them on this turn" — counts tool spans that cannot arrive.
The platform's own example manifest does set it (rossoctl/examples/mcpservers/weather_tool.yaml points at …:8335), so adding it here is consistent with the rest of the fleet; alternatively drop both claims. Either way the demo's pass criterion is unaffected — show-trace.py:28-31 keeps only spans carrying lineage.role, which are the sidecar's.

There was a problem hiding this comment.
suggestion — this row says "first as 35 separate traces", but the demo's own README says 19 (demos/lineage/README.md:7), and 19 is the number the tooling actually produces: 18 strays plus the queried trace (show-trace.py:103,109). 35 is the exchange count, not the trace count — the two numbers appear a few lines apart in the demo README and got crossed here. Worth fixing since the index row is what most people read first.

There was a problem hiding this comment.
suggestion — kubectl set env with no -c defaults to --containers='*', so this writes OTEL_EXPORTER_OTLP_ENDPOINT onto every container in the template — including the envoy-proxy sidecar the kit added in step 2 (attach-lineage.sh:218). Harmless in practice, since the sidecar reads its endpoint from the plugin config rather than that variable, but it undercuts the framing at :11 ("Nothing about the app is edited except one environment variable that the app itself defines") and it is the kind of thing a reader copies into a context where it does matter. -c agent (the app container, k8s/weather.yaml:53) makes it exact.
Related, while you are in this step: the agent's own OTLP export now goes out through its lineage sidecar with no OUTBOUND_PORTS_EXCLUDE, which is the opposite of the kit's own guidance for an app's telemetry port (attach-lineage.sh:56-57). It works because the collector host is on the plugin's default bypass_hosts, but that is currently only explained for the tool at :121-122 — worth saying it covers both pods.

nit — this row promises a verdict the code will not print for that cause. If the agent did not restart with the variable, its outbound calls carry nothing, so the queried trace holds the entry alone and show-trace.py:118-119 prints ENTRY ONLY — exactly what step 3 shows at :86. FRAGMENTED (:121) is reserved for partial propagation. "still says ENTRY ONLY (or FRAGMENTED)" would match the code.
While in this table: the likeliest real failure is missing from it — show-trace.py's --since defaults to 10m (:84), a turn can take up to 300s (ask.sh:22), and any pause between steps 3 and 5 pushes spans out of the window and yields "no sidecar spans for … in the last 10m". The :182 row attributes that message to a stale sidecar image or a restarted collector, not to window expiry.

authbridge/CLAUDE.md currently has zero references to "lineage" anywhere (verified via gh api .../contents/authbridge/CLAUDE.md). This PR adds a new demo directory and does not touch that file, so the directory tree / demo enumeration it maintains is now stale in the same way flagged for #852's kit. Not a new problem this PR introduces, but it compounds an existing one — two lineage-related additions (kit + demo) have now landed (once #852 merges) without either being reflected in CLAUDE.md. Suggest one follow-up edit to CLAUDE.md covering both once #852 lands, rather than two separate patches. |

Use the measured trace count.
Use 19 separate traces, not 35. The turn has 35 exchanges and 70 sidecar spans, but it has one entry trace plus 18 unparented outbound traces before application propagation.

authbridge/demos/lineage: the weather agent and tool from rossoctl/examples deployed plain (k8s/weather.yaml — two Deployments, two Services, one ConfigMap for the LLM; no AgentRuntime, no platform sidecar, no auth), then given lineage with the attach kit and nothing else. ask.sh sends one A2A turn from inside the cluster with a chosen trace id; show-trace.py reads the collector log and prints the trace's shape with a verdict — it refuses an entry-only trace and counts traces begun by an unparented outbound hop while this one was in flight, so the case that looks fine and is not cannot pass. Measured on kind, host Ollama qwen2.5:7b, sidecar built from rossoctl#761 @ e45bda9 (contract v1.6): capture only, one turn = 35 exchanges, 70 spans, 19 traces (the entry, plus 18 trees of an outbound 'none' hop and the tool's 'tracestate' inbound); after the app's own propagation switch (OTEL_EXPORTER_OTLP_ENDPOINT — the agent ships its instrumentation, and the kit's interlock refuses to bake it for exactly that reason): one trace, 70 sidecar spans + 82 of the apps' own, parent.source 1 wire / 34 tracestate / 0 none, 0 strays. Back-out via the kit's printed lines leaves the namespace as found. The demos index gets the demo row above the kit's; the authbridge README's demo list and the kit's README point at it.

Rebased on main after rossoctl#852 merged; the demo is the only change now. Reviewer findings (huang195 2026-09-03, CodeRabbit 2026-09-08) and a re-run of every step against the merged kit on kind (k8s 1.35): - KIT was prose only; the prerequisites block now exports it. - The tool's OTLP endpoint is stated in weather.yaml. The premise that nothing left the pod without it was wrong: the tool's code defaults the endpoint to the collector's 8335, and 4 tool spans arrive in the propagated trace (82 app spans: 78 agent + 4 tool). Explicit is better than a default hidden in the image, so it is set anyway. - Step 2's expected output and step 6 followed the pre-merge kit (`rollout undo --to-revision`); the merged kit backs out with a reverse strategic patch. Step 6 runs it (regenerated with EMIT=undo) and drops step 4's variable. - show-trace.py: kubectl's error is printed instead of a traceback; a span block without a parseable start time is skipped and reported rather than widening the stray window to the start of the log; a captured value (input.value / output.value, printed verbatim) holding a fact-shaped line can no longer relabel a span — first occurrence wins for every fact the plugin emits before the captured value, last for lineage.parent.source, repeats reported; usage names --namespace and the exit codes; the FRAGMENTED line names the outbound-root case. - ask.sh: a failed request prints what arrived and exits 1, not a traceback. - README: index row says 19 traces, not 35 (the exchange count); `set env -c agent`; the three collector ports (8335 apps, 4317 plugin, 4318 dead) and bypass_hosts covering both pods' exports; CAPTURE_IO's log boundary (demo only); a real LLM key belongs in a Secret; RBAC per step; k8s 1.29 prerequisite; RECIPE step 1 runs from the kit's directory; the interlock probe needs the image pulled; the counts are one run's and the shape is the invariant; `--since` window first in troubleshooting; ENTRY ONLY named where FRAGMENTED was promised; the Keycloak "all demos" claims exempt this demo.

Third pass. Every round-1 thread is fixed in e3412ed, verified against the current head rather than the reply: KIT exported in the prerequisites block (README.md:30), the tool carries OTEL_EXPORTER_OTLP_ENDPOINT (weather.yaml:155-160), show-trace.py catches CalledProcessError and prints kubectl's stderr, no-start-time blocks are skipped and counted instead of sorting first, the usage line names --namespace and the exit codes, the index row says 19, set env names -c agent, the bypass_hosts explanation covers both pods, the LLM-key comment points at a Secret, the capture-io retention boundary is stated, RBAC is listed, --since leads the no-spans row, step 5's failure row says ENTRY ONLY, and step 6 uses the reverse strategic patches the merged kit actually prints. CodeRabbit's three remaining threads are on lineage-attach/* — merged as #852, out of this diff.
I also checked the demo's claims about the merged kit and plugin rather than taking the run log on faith:
- the kit's interface (
DEPLOY/NAMESPACE/CAPTURE_IO/SIDECAR_IMAGE/PROXY_INIT_IMAGE, andEMIT=undo NAME= NAMESPACE=for the regenerated back-out) matchesattach-lineage.sh/sidecar-patch.shonmain; all four cross-doc anchors resolve; bypass_hostsdoes default tootel-collector+otel-collector.*, so both pods' own exports are span-free with noOUTBOUND_PORTS_EXCLUDE— and that default is empty, so 11434 does stay in the redirect as the manifest comment claims;- the sidecar container is named
envoy-proxy(the troubleshooting row is right) and is a restartable init container, which kubectl'sprintPoddoes count in READY — so2/2after attach and1/1after back-out are both correct; self_idis written explicitly by the kit, so the demo needs no/shared/client-id.txt— which is what lets it run with no operator and no Keycloak;- every
lineage.*/input.value/output.valuekeyshow-trace.pyreads exists in the merged plugin, and the first-wins / last-wins-for-parent.sourcescheme infacts()matches the producer's real append order on both the request span (plugin.go:583-594) and the response span (:818-835). That reasoning is the load-bearing part of the script and it holds; - the measured blocks are self-consistent (35 exchanges × 2 = 70 spans; 1+16+2+16 = 35; 1 wire + 34 tracestate = 35; 18 strays plus the queried trace = the headline's 19), and

nit — #761 merged on 2026-09-08 at 22:34Z, about 80 minutes before this branch's last push, so authbridge/authlib/plugins/lineage/ is on main now. The instruction still works — RECIPE step 1 already covers both cases ("main once #761 has merged; the #761 branch until then") — but the parenthetical here reads as though the plugin is still on a branch, and the PR description's "build one from the #761 tree" is now "from main".

nit — kubectl logs deploy/otel-collector resolves the Deployment, then lists pods to pick one, then reads pods/log. list pods in rossoctl-system is the third verb, and it is the one a restricted role most often omits: someone holding get deployments + get pods/log but not list pods gets Error from server (Forbidden) and lands on the "no sidecar spans" troubleshooting row (window expiry, stale image) rather than on RBAC.
Worth naming, since this bullet exists precisely for the reader running against something stricter than a kind admin.

There was a problem hiding this comment.
nit — facts() runs here on every sidecar block, including the queried trace's own: the tid.group(1) != trace_id test is at :82, after this call. spans_for has already put those same blocks through facts(), so an ambiguous block belonging to the queried trace increments the global counter twice and the warning at :127 over-reports the block count.
Only the number is wrong — the warning still fires when it should, and nothing downstream reads it — so this is cosmetic. Moving the trace-id test ahead of facts(block) fixes the count and skips the attribute parse for every block that cannot be a stray anyway.

nit — with pipefail and set -e, a failed turn (curl's --max-time 300 expiring, a non-2xx answer, an unschedulable pod) makes the kubectl run | python3 pipeline non-zero and the script exits before reaching this line, so the collector grep hint is dropped in exactly the case where someone wants to check whether spans landed anyway.
Nothing load-bearing is lost — the id is echoed at :21 and the python at :31-34 prints what arrived — so this is only the hint. Folding the grep -c into the leading echo, or || true on the pipeline, keeps it on both paths.

Summary
authbridge/demos/lineage/: the Weather Agent pair fromrossoctl/examples, deployed plain, then given per-request lineage with thelineage attach kit (#852, merged) and nothing else. Six steps. You see
the same turn twice: 19 separate traces when the app forwards no
traceparent(the entry, plus 18small trees the sidecar roots for each un-propagated call), then one trace of 70 sidecar spans with
one root once the app's own propagation is switched on. Nothing about the app is edited except one
environment variable the app itself defines.
Rebased on
mainafter #852 merged — the diff is now the demo alone: four files underauthbridge/demos/lineage/, the demo row and the kit row in the demos index (the kit's own row did notsurvive #852's squash), one bullet in
authbridge/README.md, and a two-line cross-link in the kit'sREADME.
Depends on #761 for the sidecar image only: the kit refuses the published default image until a
release carries
lineage-telemetry, so the prerequisites build one from the #761 tree (RECIPE step 1).Nothing else in this PR touches #761.

weather_tool.py:66in the published image), so its export did occur and its 4 spans do arrive —verified in the propagated trace. Explicit is still better than a default hidden in the image, so the
manifest sets it, and the README's two claims stand with the 78/4 split stated.
Suggestions and nits:
show-trace.pyprints kubectl's own error instead of a traceback and skips aspan block with no parseable start time (it would have widened the stray window to the start of the
log); the usage line names
--namespaceand the exit codes; the index row says 19 traces (35 was theexchange count);
set envnames the app container; the three collector ports (8335 apps, 4317 plugin,4318 dead on the stock chart) are explained once, and
bypass_hostscovering both pods' own exportswith it; the API key comment points at a Secret; RBAC per step is listed; the
--sincewindow is thefirst troubleshooting cause for "no spans"; the step-5 failure row says
ENTRY ONLY; the demos index andauthbridge/README.mdno longer claim Keycloak for this demo.Found while re-running against the merged kit, not in the review: #852's final kit backs out with a
reverse strategic patch, not
rollout undo --to-revision. Step 2's expected output and all of step 6described the old kit; both are rewritten and were run verbatim.
ask.shhad the sametraceback-on-failure shape as the
show-trace.pyfinding (a wrong service name printed a Pythontraceback); it now prints what arrived and exits 1.
Verification
Every step run verbatim on kind
rossoctl(Kubernetes v1.35.0) with a sidecar built from #761's currenthead, then backed out. The measured blocks in the README are that run's output.
show-trace.pyexitcodes checked on all four paths (good shape 0, entry-only 2, unknown id 1, unreadable log 1 with
kubectl's message). The bake interlock on the agent image: exit 3 with the quoted message. Gates that read
these files: ruff, Bandit and CodeQL (python) on
show-trace.py; shellcheck at error severity onask.sh(clean at every severity too); the CI yamllint job lints
.github/workflows/only, soweather.yamlwaslinted locally.
CodeRabbit's three threads on
lineage-attach/*(TLS on capture, ConfigMap ownership,CONTAINER_TOOLdispatch) are about the kit, which merged as #852 and is no longer in this diff; they belong to a kit
follow-up.
