feat(compute): compute logs <id> — container stdout/stderr from the CLI

[tonychang04]

Why

Customer thread today: an agent using the CLI reported "The CLI did not expose a Compute log source" and fell back to driving the dashboard in Chrome. It was right — the dashboard Logs panel (cloud-backend #662 / oss #1480, June) never got a CLI surface; compute logs had been renamed to compute events (#96) with a note that container logs would reclaim the name when they landed.

Every operation a human can do in the UI must be reachable from the CLI + skills.

What

• compute logs <id> [--limit 1-1000] [-f|--follow] [--next-token <t>] → GET /api/compute/services/:id/logs
• --json emits { lines, nextToken } so agents can page forward with --next-token
• --follow polls every 2s (matches the server-side rate limiter tuned for the dashboard's ~2s poll)
• README section; stale roadmap comment in events.ts updated
• vitest: URL/limit clamp, next_token forwarding, formatting, --json passthrough

Companion skills PR: InsForge/insforge-skills (compute logs in SKILL.md, diagnostics.md, compute-deploy.md).

Test

npx vitest run src/commands/compute/logs.test.ts → 5 passed; eslint clean; tsc clean for touched files.

Summary by cubic

Adds the compute logs <id> command so container stdout/stderr is reachable from the CLI, matching the dashboard's Logs panel. Previously only compute events (machine lifecycle events) was exposed; the logs name was vacant after the earlier rename.

Follow-mode correctness

• --follow polls every 2s; advancing-cursor pages print verbatim, while frozen or missing cursors dedupe already-printed lines so nothing is dropped or repeated.
• The follow watermark ignores NaN and implausibly-future timestamps and never moves backward; the future bound is scoped per page with trust earned once and never revoked.
• Transient failures (429/5xx) on any follow fetch — including the initial one — retry with capped backoff up to 5 consecutive failures; one-shot mode still fails fast.

Output and safety

• Log lines are sanitized at the fetch boundary, stripping ANSI/OSC and C1 control sequences from every printable field in all output modes, including --json.
• --limit clamps to 1–1000 with malformed values falling back to the default; --json returns { lines, nextToken } for paging with --next-token.
• Follow mode announces itself on stderr before the first fetch and during each retry so backoff never looks hung.

^{Written for commit 67ba77d. Summary will update on new commits.}

Note

Add compute logs <id> command to fetch container stdout/stderr from CLI

• Adds the compute logs <id> command with --limit (default 100, clamped 1–1000), -f/--follow (polls every 2s via nextToken), --next-token, and root --json mode
• fetchComputeLogs calls GET /api/compute/services/:id/logs, URL-encodes the service id, and normalizes the response to always return { lines, nextToken }
• formatLogLine renders each line as ISO timestamp plus optional [region instance] block and message; falls back to omitting brackets when region/instance are absent
• Registers the command in src/index.ts and updates comments in src/commands/compute/events.ts to distinguish lifecycle events from container logs
• Behavioral Change: --follow with --json prints each line as a separate JSON object rather than a single payload; non-JSON follow mode prints Following logs... to stderr

^{Macroscope summarized 4a8805e.}

Walkthrough

Adds compute logs <id> for container stdout/stderr retrieval. The command supports limits, pagination, JSON output, and two-second follow polling. It is registered under compute, documented in the README, and distinguished from compute events.

Changes

Compute log retrieval

Layer / File(s)	Summary
Log retrieval contracts and formatting src/commands/compute/logs.ts	Defines log result interfaces, sanitizes log fields, parses limits, formats timestamps, and normalizes paginated responses.
CLI command and follow polling src/commands/compute/logs.ts, src/index.ts	Registers compute logs <id> with JSON, cursor, limit, telemetry, follow polling, deduplication, retry, and cursor advancement behavior.
Command behavior validation and guidance src/commands/compute/logs.test.ts, src/integration/compute.test.ts, README.md, src/commands/compute/events.ts	Tests retrieval, pagination, sanitization, follow mode, retries, NDJSON, malformed responses, timestamps, telemetry, and limit parsing. Documents the command and distinguishes it from compute events.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to e784f

The command adds authenticated container-log access with bounded inputs and output sanitization, but malformed responses can stop follow mode or misrender missing timestamps, while terminal pagination semantics could suppress some valid lines; the change is mergeable with explicit owner awareness and follow-up.

Poem

A rabbit watched the log lines flow

JSON follow output breaks

When --json and --follow are combined, this branch writes each log line as a separate JSON object and never emits the page cursor, causing stdout to be neither the documented { lines, nextToken } result nor a single parseable JSON value.

Knowledge Base Used: CLI command runtime

[jwfing]

Summary
The change wires the compute container logs endpoint into the CLI with docs and focused tests, and I found no blocking functionality, security, or performance issues.

Requirements Context
I based intent on PR #287: add compute logs <id> [--limit 1-1000] [-f|--follow] [--next-token <t>] for GET /api/compute/services/:id/logs, emit { lines, nextToken } under --json, and poll every 2s in follow mode. PR #96 previously renamed lifecycle-event output to compute events and reserved compute logs for real stdout/stderr. The local README now documents the command, and the public Custom Compute docs say logs should be tail-able in dashboard, CLI, or MCP; DEVELOPMENT.md provides the command, output, telemetry, and skills-sync conventions.

Findings
Critical
(none)

Suggestion

• src/commands/compute/logs.ts:66-66: Number(opts.limit) || 100 means --limit 0 becomes 100, not the documented lower clamp of 1. The upper clamp is tested, but the lower-bound edge is not; parsing first, defaulting only on invalid input, then clamping would match the 1-1000 contract.
• src/commands/compute/logs.ts:69-77, src/commands/compute/logs.ts:88-96: --json --follow switches from the documented { lines, nextToken } envelope to newline-delimited individual log-line objects and does not expose the cursor. Also, let token = result.nextToken drops an explicit --next-token if the first follow fetch returns no replacement cursor. Clarifying/locking the follow JSON format and adding fake-timer coverage for cursor polling would reduce agent-facing ambiguity.
• src/commands/compute/logs.ts:1-102, DEVELOPMENT.md:33-60: the new command only uses legacy reportCliUsage; it does not emit trackCommandUsage('compute', 'logs', ...), while the development guide calls PostHog the product telemetry path and every existing compute subcommand uses it. For follow mode, success telemetry likely needs to fire after the initial successful fetch or when entering follow, since the current success path after the loop is unreachable.

Information

• src/index.ts:75-83, src/index.ts:270-280, src/commands/compute/logs.ts:44-50: software-engineering conventions are otherwise followed: ESM imports, command registration, OSS API usage, path encoding, and query encoding are consistent with neighboring compute commands.
• src/commands/compute/logs.test.ts:39-67: tests cover endpoint URL generation, upper limit clamp, next_token forwarding, text formatting, and non-follow --json pass-through. I did not execute the suite because the review request was explicitly read-only.
• src/commands/compute/logs.ts:63-67, src/lib/api/oss.ts:234-317: no security-relevant regression found; the command requires auth and sends encoded path/query inputs through ossFetch. Container logs may contain sensitive application data, but returning them is the explicit feature.
• src/commands/compute/logs.ts:30-30, src/commands/compute/logs.ts:66-66, src/commands/compute/logs.ts:88-96: no performance blocker found; one-shot fetches are limit-capped and follow mode polls at the stated 2s cadence. The unbounded loop is intentional for --follow.

Verdict
approved per the requested rubric: no Critical findings. Suggestions are non-blocking, and human green-check approval remains separate.

Summary
The PR adds the intended compute logs <id> CLI surface and looks mergeable, with a few non-blocking engineering follow-ups.

Requirements Context
I used the PR description, the added README section at README.md:1094-1103, the local compute command conventions, and DEVELOPMENT.md:1-59 as the basis for intent. I also checked the public InsForge backend source and did not find a conflicting contract: the backend schema confirms { lines, nextToken } with numeric timestamps, and the route uses /api/compute/services/:id/logs.

Findings

Critical
(none)

Suggestion

• src/commands/compute/logs.ts:6-114 uses only reportCliUsage, so this new command will not emit the current PostHog trackCommandUsage('compute', 'logs', ...) event that the rest of the compute group emits. DEVELOPMENT.md:53-59 says new commands should use the PostHog path rather than the legacy OSS usage path; consider matching the other compute commands and only passing non-sensitive metadata such as result count, follow mode, and success/failure.
• src/commands/compute/logs.ts:100-108 implements the core --follow behavior, but src/commands/compute/logs.test.ts:30-68 only covers one-shot fetches. A fake-timer test for second-poll cursor forwarding plus NDJSON/non-JSON follow output would cover the highest-risk behavior in this PR.
• src/commands/compute/logs.ts:78 maps --limit 0 to the default 100 because of Number(opts.limit) || 100, rather than lower-clamping to 1 as the documented 1-1000 range implies. This is minor, but a finite-number parse before clamping would make the contract exact.

Information

• Software engineering: command registration and ESM import style match the surrounding compute command layout in src/index.ts:79-280 and src/commands/compute/*.ts.
• Functionality: one-shot endpoint construction, service-id encoding, next_token forwarding, formatted output, and JSON passthrough are covered in src/commands/compute/logs.test.ts:39-68.
• Security: no SQL/shell paths or new dependencies are introduced; service IDs and query parameters are encoded in src/commands/compute/logs.ts:54-58, and text-mode log messages strip terminal control sequences in src/commands/compute/logs.ts:37-47.
• Performance: fetches are page-bounded to at most 1000 lines and follow mode polls every 2s in src/commands/compute/logs.ts:78-105; no N+1 or blocking hot-path work found.

Verdict
Approved per the requested rule: no Critical findings. Human maintainers should still decide whether to address the suggestions before merging.

[jwfing]

Summary

compute logs <id> is a clean, correctly-wired addition that closes a real CLI/dashboard gap — I verified its wire contract against the actual OSS backend route and found no blocking correctness, security, or performance issues; the notes below are all non-blocking.

Reviewed at head 51e7e36d (the head moved from 4a8805e6 mid-review — the fix(compute-logs): sanitize terminal escapes… commit is included in everything below).

Requirements context

The repo has no /docs/superpowers/ directory. docs/specs/ exists but holds only diagnose and db-migrations design docs — no spec/plan matches this PR, so I assessed against the PR description, DEVELOPMENT.md (the repo's written conventions, referenced by .claude/skills/cli-development/SKILL.md), and the sibling compute events command.

I did independently verify the intent claim rather than take it on faith. Against InsForge/InsForge@main:

• backend/src/api/routes/compute/services.routes.ts:648-673 — GET /:id/logs, guarded by verifyAdmin + computeLogsRateLimiter, reads req.query.limit and req.query.next_token. Matches the CLI's path and param names exactly.
• packages/shared-schemas/src/compute-services-api.schema.ts:159-174 — { lines: { timestamp: number, message: string, instance?, region? }[], nextToken: string | null }. The interfaces at src/commands/compute/logs.ts:18-28 match the server schema field-for-field, including timestamp being epoch-ms (normalised in fly.provider.ts:549-553, 0 on unparseable) — so new Date(...).toISOString() at logs.ts:44 cannot throw on a well-formed response.
• backend/src/utils/response.ts:22-24 — successResponse does not wrap, so res.json() yields the object directly. Correct.
• computeLogsRateLimiter is 120 req/min per IP (backend/src/api/middlewares/rate-limiters.ts:106-122); the 2s follow interval is 30 req/min. Comfortably inside budget for a single tail.

No hallucinated or stale API usage. Also worth noting: ServiceLogs.tsx in the dashboard re-fetches the whole recent window and never passes nextToken, so this CLI is the first consumer of the cursor-paging path — which is why the --follow notes below matter more than they otherwise would.

Verification performed: npm ci + npx vitest run src/commands/compute/logs.test.ts → 6 passed. npm run build → clean. npm run lint → 802 passed / 1 failed, but the failure is src/lib/cloudflare.test.ts dying on listen EADDRINUSE 127.0.0.1:8787 in my sandbox — an untouched file, environmental, not caused by this PR. I also ran negative controls and a probe harness that drives the real registerComputeLogsCommand through Commander; findings below marked "reproduced" come from that harness, not from reading.

Findings

Critical

(none)

Suggestion

Software engineering — --follow has zero test coverage, and it is the riskiest code in the PR (src/commands/compute/logs.ts:100-109, src/commands/compute/logs.test.ts:20-73)

Negative control: I deleted the entire if (opts.follow) { … } block at logs.ts:100-109 and all 6 tests still passed. The polling loop, cursor advancement, the --json NDJSON branch at logs.ts:89, and the stderr banner at logs.ts:101 are all unexercised. The one-shot paths and sanitizeLogMessage are genuinely covered (neutering the sanitiser to return message does fail a test), so the suite is not vacuous — the gap is specifically the follow loop. A test with fake timers (or an injectable interval/stop predicate) that drives two polls and asserts (a) the second fetch carries next_token=<cursor from poll 1> and (b) --json --follow emits one object per line would cover it. This is also what makes the next two items hard to catch.

Functionality — a null cursor turns --follow into an infinite duplicate-printer (src/commands/compute/logs.ts:102-107)

if (result.nextToken) token = result.nextToken keeps the previous token, which is right, but there is no handling for token being null from the start. fetchComputeLogs at logs.ts:62 deliberately normalises a missing/empty nextToken to null — so the author already anticipated that the server may not hand back a cursor. When that happens on the first fetch and lines are non-empty, every subsequent poll calls fetchComputeLogs(id, { limit, nextToken: undefined }), i.e. re-requests the most recent limit lines and re-prints all of them.

Reproduced with the real command: a server that always returns 2 lines and nextToken: null produced

/api/compute/services/svc/logs?limit=100   (x5, no cursor ever attached)
line-A, line-B, line-A, line-B, line-A, line-B, line-A, line-B

With --limit 1000 that is 1000 duplicate lines every 2 seconds. The same path is reachable via --follow --next-token <t>: if the resumed page returns no further cursor, the tail silently jumps back to the recent window instead of staying where the user asked. Non-blocking because it is server-conditional and Ctrl+C-able, but worth handling — either dedupe against the last printed (timestamp, message) boundary, or refuse to re-fetch cursorless (keep polling with the last known token, or exit with a clear "server returned no cursor; cannot follow" message).

Functionality — one transient failure ends the tail (src/commands/compute/logs.ts:103-108)

There is no try/catch inside the while (true). Reproduced: injecting a single 429 on the second poll ends the command after one printed line. A long-running tail will meet a 429 (the limiter is per-IP, so several tails plus dashboard tabs behind one NAT egress share the 120/min budget), a 502, or a laptop-sleep network blip. The backend also puts a 15s AbortSignal.timeout on the upstream Fly call (fly.provider.ts:525), so a slow Fly can surface as a 5xx. A bounded retry with backoff on transient errors — while still failing fast on 401/403/404 — would match what "keep polling until Ctrl+C" promises in the help text.

Software engineering — the new command emits no PostHog telemetry, and uses the path DEVELOPMENT.md explicitly forbids (src/commands/compute/logs.ts:6, :83, :95, :111, :113)

DEVELOPMENT.md:58-60 states verbatim: "Do not use reportCliUsage for new commands — that legacy OSS telemetry path has been removed from create, link, and docs. PostHog is the path going forward." src/lib/command-telemetry.ts:11-13 adds: "Every command should emit exactly one event per invocation." This file uses reportCliUsage at four sites and calls trackCommandUsage nowhere. 8 of the 9 compute command files call trackCommandUsage; logs.ts is the only one that does not — including events.ts:29,49, the command it is modelled on, which emits it on both the success and error path. Net effect: the new surface is invisible in the PostHog dashboards, which is a shame given the PR's own motivation is "an agent could not find a CLI log source." Adding trackCommandUsage('compute', 'logs', success, { result_count, follow }) (counts/booleans only — never the log text) would match the group. Related: even once added, --follow never reaches line 111, so a successful tail reports nothing; emitting before entering the loop would fix that.

Security — 8-bit C1 controls bypass the new sanitiser, in both output modes (src/commands/compute/logs.ts:37, :89)

The sanitiser is a genuinely good addition and the arms are more robust than they look: because U+001B (ESC) is itself inside the C0 class, any ESC-led sequence is defanged even when the specific CSI/OSC arms miss it. I confirmed this — a truecolor colon-SGR ESC[38:2:255:0:0m is not matched by the CSI arm ([0-9;?] excludes :), but the loose ESC still gets stripped, leaving inert text.

The residual is the 8-bit C1 forms, which contain no ESC. Reproduced against the shipped regex:

input	after sanitizeLogMessage
U+009B (8-bit CSI) + 31mRED	unchanged
U+009D (8-bit OSC) + 0;pwned-title	passes through (only the BEL is stripped)
U+0090 (8-bit DCS) + 1;2p payload	unchanged

And the code comment at logs.ts:35 ("JSON mode is safe as-is — JSON.stringify escapes controls") is true only for C0: JSON.stringify emits C1 raw, so --json --follow at logs.ts:89 pipes U+009B straight to the terminal. Exploitation needs a compromised app and a terminal that honours 8-bit C1 in UTF-8 (xterm in some configurations; VTE/iTerm2/Windows Terminal generally do not), which is why this is a Suggestion rather than a blocker — but the fix is one character range: add �-� to the stripped class, and sanitise (or \uXXXX-escape) before serialising in the JSON path.

Software engineering — no integration coverage for the new endpoint (src/integration/compute.test.ts:90-98)

compute events --json has an integration test that runs against a real service; compute logs --json was not added alongside it. That suite is the only place the CLI↔backend wire shape is actually exercised end-to-end, and it is the natural home for a { lines, nextToken } assertion.

Information

• --limit 0 silently becomes 100, not 1 (src/commands/compute/logs.ts:78). Number(opts.limit) || 100 treats 0 as absent, so the documented 1-1000 lower bound is never applied to an explicit 0; --limit abc also silently becomes 100. This exactly matches events.ts:23, so it is a consistent house pattern rather than a regression — flagging only because the help text at logs.ts:70 advertises 1-1000. Parsing first, defaulting on NaN, then clamping would make the two agree.
• Fractional limits are forwarded verbatim (src/commands/compute/logs.ts:78). Reproduced: --limit 2.7 sends limit=2.7; the backend clamp preserves it and lines.slice(-2.7) truncates toward zero, so it degrades to 2 lines. Harmless; Math.floor would tidy it.
• The sanitiser drops newlines with no replacement (src/commands/compute/logs.ts:37). is in the stripped class, so a multi-line message (a stack trace delivered as one Fly entry) comes out as line1line2 — words glued together. Removing newlines is the right call for a line-oriented tail (it stops a log line from forging additional output lines), but replacing the stripped C0 runs with a single space instead of '' would keep it readable. Note --json keeps the \n, so the two modes disagree on content.
• region / instance are interpolated unsanitised (src/commands/compute/logs.ts:45,47). These come from Fly's API rather than from container output, so the trust level differs and this is fine — noting it only because the surrounding line is otherwise fully defanged.
• Test import style (src/commands/compute/logs.test.ts:77). The new sanitizeLogMessage describe block uses an inline await import('./logs.js') while the rest of the file uses a top-level import { … } from './logs.js'. No functional difference; the top-level import would be consistent.
• DEVELOPMENT.md:74-84 skills-sync checklist is satisfied — the PR body names the companion InsForge/insforge-skills PR, exactly as the checklist asks.

Performance

No issues. The follow loop awaits a real timer (logs.ts:104) so nothing blocks the event loop; lines are printed and discarded rather than accumulated, so a long tail has flat memory; there is no N+1 (one request per poll) and no new DB queries or indexes. The 2s interval against a 120/min per-IP limiter leaves headroom. The only nit: the interval is fixed with no backoff, so tailing an idle service costs a steady 30 req/min indefinitely — fine at current scale, and it matches the dashboard's own cadence.

Verdict

approved — no Critical findings. The endpoint contract, auth, project scoping, and response shape all check out against the live backend source, and the sanitiser addition in 51e7e36d was the right instinct. The two I would most like to see before merge are the --follow test coverage and the trackCommandUsage switch (the latter is an explicit written "Do not" in DEVELOPMENT.md), but neither blocks. (Informational — the GitHub green check is a separate human action.)

Summary
The PR adds compute logs <id> with documented paging, JSON, and follow behavior; I found no critical blockers.

Requirements Context
I used the PR title/description as the primary intent: expose GET /api/compute/services/:id/logs via compute logs <id> with --limit, --follow, --next-token, and root --json. The local README documents the same user-facing behavior at README.md:1094-1102. I did not find additional local API contract docs or linked issue text in this checkout, so backend specifics were assessed against the PR description and README.

• Functionality: src/commands/compute/logs.ts:124-131 uses only timestamp > lastTs when follow mode has no cursor. Distinct lines that arrive with the same timestamp as the latest printed line can be silently dropped. Consider a small seen set or composite key for the current timestamp window.
• Security: src/commands/compute/logs.ts:56-57, src/commands/compute/logs.ts:70-76, src/commands/compute/logs.ts:105-108 sanitize only message, while region, instance, and any extra preserved fields can still be printed in text/NDJSON. If fetch-boundary sanitization is meant to cover all output, normalize to the documented shape and sanitize all printable string fields.

Information

• Software engineering: src/commands/compute/logs.test.ts:53-148 covers endpoint construction, limit clamping, cursor forwarding, formatting, JSON output, follow polling, no-cursor dedupe, and terminal-control stripping. I did not run tests because the review instructions were read-only/no mutating commands.
• Performance: src/commands/compute/logs.ts:30, src/commands/compute/logs.ts:64-68, src/commands/compute/logs.ts:125-134 keep each fetch bounded by a clamped limit and poll every 2 seconds in follow mode. No N+1 query pattern, unbounded response size, or hot-path blocking work stood out.
• Project conventions: src/index.ts:75-83, src/index.ts:270-280, src/commands/compute/logs.ts:80-141 match the repo’s command registration pattern, ESM import style, root --json handling, and non-sensitive telemetry properties.

Verdict
Approved: no Critical findings.

Addendum — re-review at 5e2168d

My first review posted while the branch was moving: it was written against 51e7e36 but GitHub attached it to db86956. Three commits have landed since (7574fca, ae71eba, db86956, then 5e2168d). Here is a re-review of the current head, with every claim re-run against the new tree.

What is now fixed — verified, not assumed

Each of these was checked with a negative control (break the fix, confirm a test goes red):

My finding	Status at 5e2168d
--follow had zero coverage	Fixed. Deleting the follow block now fails 2 tests (it failed 0 before). Cursor forwarding, cursorless dedupe and --json --follow NDJSON are all exercised with fake timers.
reportCliUsage instead of PostHog	Fixed. logs.ts:6 now imports trackCommandUsage, emitted once before the follow loop so a tail is counted, and on the error path. reportCliUsage is gone. Matches DEVELOPMENT.md:58-60 and the other 8 compute commands.
8-bit C1 bypass	Fixed. �-� added, and sanitising moved to the fetch boundary in fetchComputeLogs, so --json is covered too — the mode JSON.stringify left raw. Removing the C1 range fails 2 tests.
--limit 0 → 100	Fixed. parseLimit (logs.ts:47-51) does finite-check → Math.trunc → clamp, so 0 → 1 and 2.7 → 2. Directly unit-tested.
One transient failure ends the tail	Fixed. logs.ts:139-149 retries on isTransientApiError with exponential backoff capped at 30s, giving up after 5 consecutive failures. I checked this against the real error path, not just the mock: ossFetch throws new CLIError(message, 1, err.error, res.status) (src/lib/api/oss.ts:313) and tags network failures NETWORK_ERROR, and TRANSIENT_4XX_STATUSES (errors.ts:12) is {408, 429} — so the server's 429 limiter and 5xx genuinely hit the retry arm while 401/403/404 still fail fast. isTransientApiError is pre-existing at errors.ts:72-77, correctly reused rather than reinvented.
Newline gluing	Fixed. C0 runs collapse to a single space instead of ''.
No integration coverage	Fixed. src/integration/compute.test.ts:100-112.

npx eslint clean on all three changed files; npm run build (incl. DTS) succeeds; the logs suite passes.

Remaining — all Suggestion, none blocking

Functionality — the duplicate flood is only half fixed: a frozen cursor still repeats every poll (src/commands/compute/logs.ts:130-136, :150)

The comment says "no filter is applied while a token advances" — but the condition tests whether a token exists, not whether it advanced:

const fresh = token ? page.lines : page.lines.filter((l) => l.timestamp > lastTs);
…
if (page.nextToken) token = page.nextToken;   // stale token is retained on null

When a page comes back with nextToken: null, token correctly keeps its last good value — but the next poll then re-queries that same frozen cursor and skips the dedupe filter because token is truthy. Reproduced by driving the real command at 5e2168d:

urls:    …/logs?limit=100
         …/logs?limit=100&next_token=tokA
         …/logs?limit=100&next_token=tokA      <- frozen
         …/logs?limit=100&next_token=tokA
printed: one, two, three, two, three, two, three

This is the same failure mode as my original finding, just reached from the other side. fetchComputeLogs:74 normalises an empty-string nextToken to null, and the backend's fly.provider.ts:566-576 can hand back an empty token when its digit regex misses — so this is the same likelihood as the case that was fixed. Gating the filter on advancement rather than existence covers both: track the token used for the request and apply the timestamp filter whenever the new page's cursor did not move.

Functionality — the cursorless dedupe silently drops lines that share the boundary millisecond (src/commands/compute/logs.ts:134-138)

l.timestamp > lastTs is strict, and timestamp is millisecond-resolution (fly.provider.ts:551 parses RFC3339 into epoch ms). A container that emits more than one line per millisecond — routine under load — will straddle the boundary. Reproduced: initial page [A@5]; next page [A@5, B@5(new), C@6(new)] printed only

…005Z  A-at-5
…006Z  C-at-6-NEW

B@5 — a genuinely new line — is gone, with no indication. This is a worse failure mode than the duplicates it replaced: a tail that quietly loses lines undermines the debugging use case the PR exists for. Deduping on identity (e.g. a Set of timestamp + "�" + message for the boundary millisecond, or the count of already-seen lines at lastTs) rather than on a strict timestamp comparison avoids it. Worth a test at exactly this boundary — the current cursorless test uses distinct timestamps (5 and 9), so it passes either way.

Software engineering — --json fidelity: newline stripping is not needed in the JSON path (src/commands/compute/logs.ts:38-56, :76-79)

Moving sanitisation into fetchComputeLogs was the right call for C1, but it also applies the newline collapse to the --json payload, which is the surface agents consume. Reproduced at 5e2168d:

in : "Error: boom\n    at foo (a.js:1)\n    at bar (b.js:2)"
out: "Error: boom     at foo (a.js:1)     at bar (b.js:2)"

JSON.stringify already escapes \n as the two characters \ + n — a raw newline can never reach the terminal through the JSON path — so nothing is gained by removing it there, and stack-trace structure is lost for exactly the consumer the PR was written for. Keeping \n in the data and collapsing it in formatLogLine (the human path, where forged output lines are the actual risk) would be lossless in both modes.

Information

• The trackCommandUsage success call (logs.ts:96-99) is unasserted — deleting it leaves the suite green. The error-path call is likewise uncovered. Not worth a dedicated test on its own, but expect(trackCommandUsage).toHaveBeenCalledWith('compute', 'logs', true, …) folded into an existing case would pin the event name, which DEVELOPMENT.md:44-46 asks to keep stable.
• formatLogLine is still exported but its dedicated unit test was dropped in 7574fca; its no-region/instance branch now survives only via the follow tests. Minor.

Verdict (unchanged)

approved — still zero Critical. The three remaining items are all conditional on provider cursor behaviour or sub-millisecond log bursts, are non-destructive, and are Ctrl+C-able in a foreground command. Round 2 and 3 addressed the substance of every point I raised, and I verified the fixes rather than taking the commit messages for them. Of what is left, the frozen-cursor repeat and the same-millisecond drop are the two I would still fix, since they are two halves of the same --follow correctness question. (Informational — the GitHub green check remains a separate human action.)

[jwfing]

Summary
The command largely matches the stated CLI surface, but --follow has a cursor fallback bug that can break tailing when the API stops returning nextToken.

Requirements Context
I used the PR description at #287, the local README addition at README.md:1094-1103, and the prior local history for compute logs -> compute events (61b350a) as the basis for intent. The expected behavior is compute logs <id> [--limit 1-1000] [-f|--follow] [--next-token <t>] against GET /api/compute/services/:id/logs, with non-follow --json returning { lines, nextToken } and follow mode polling every 2s.

Findings

Critical

• src/commands/compute/logs.ts:130-156 - --follow never clears a stale cursor. If an earlier response sets token and a later poll returns nextToken: null, line 156 leaves the old token in place. The next loop still calls the API with that stale token and line 151 stays in the cursor branch, so the no-cursor dedupe fallback described in the comment never activates. This can repeatedly re-fetch and print the same batch once new lines appear after the stale cursor. Set token from each response, including null, and add a regression test for the cursor-to-no-cursor transition.

Suggestion

• src/commands/compute/logs.ts:151-154 - The no-cursor fallback dedupes only by timestamp > lastTs. If two distinct log lines share the same timestamp, a later line can be dropped. If this fallback is meant to be reliable, keep a small fingerprint/window of printed lines rather than using timestamp alone.
• src/commands/compute/logs.ts:1-6 / src/commands/compute/events.ts:6-49 - The new command uses trackCommandUsage, but unlike the other compute commands it does not call reportCliUsage('cli.compute.logs', ...). If /api/usage/mcp coverage matters for agent/skills visibility, add the matching success/failure calls.

Information

• Software engineering: command registration, URL encoding, limit clamping, JSON passthrough, formatting, and focused unit/integration coverage follow nearby compute command patterns overall.
• Functionality: aside from the follow cursor fallback above, the implementation covers the claimed endpoint, --limit, --next-token, non-follow JSON, and NDJSON follow behavior.
• Security: no new dependencies; service IDs and cursors are URL-encoded; requireAuth() is preserved; log messages are sanitized before text or JSON output. I did not see SQL/shell injection or secret logging introduced.
• Performance: per-request fetches are capped by limit and follow polling is bounded at 2s plus transient-error backoff. The intentional infinite tail loop is user-controlled via --follow.
• Verification: I did not run tests because this checkout has no node_modules installed and the review was constrained to read-only commands; I inspected the tests and ran read-only diff checks.

Verdict
Request changes due to the blocking follow-mode cursor bug.

[jwfing]

Closing note — re-verified at 7d29de0

7d29de0 landed while I was writing the addendum. Re-checked against the current head; verdict unchanged (approved, zero Critical).

Fixed and verified:

• Same-millisecond drop (my addendum finding) — the filter is now l.timestamp > lastTs || (l.timestamp === lastTs && !lastTsKeys.has(lineKey(l))) with a key set for the boundary millisecond (logs.ts:140-146, :162-176). Negative control: reverting to the old strict > turns the extended cursorless test red, so the sibling-at-the-same-timestamp case is genuinely pinned. The bookkeeping is right on the paths that matter — newTs can only be >= lastTs given the filter, and the set is cleared exactly when the boundary moves.
• region / instance sanitised (my Information note) — logs.ts:81-89, now normalising to the documented shape rather than spreading the raw object.

npx eslint clean, npm run build succeeds, logs suite green.

Still open (both Suggestion, both reproduced at 7d29de0):

1. Frozen cursor still repeats (logs.ts:161-165). The token ? page.lines : … branch is unchanged, so the dedupe is still gated on a token existing rather than advancing. Driving the real command with a provider that returns tokA once and then nextToken: null:

   urls:    …?limit=100 / …&next_token=tokA / …&next_token=tokA / …&next_token=tokA
   printed: one, two, two, two
   

   Note this is the one path the new key-set does not protect, precisely because the filter is skipped. Passing the same lineKey filter through whenever the returned cursor equals the one just used would close it with the machinery already in the file.

2. --json still collapses newlines (logs.ts:38-56). "Error: boom\n at foo" → "Error: boom at foo" in the outputJson payload. JSON.stringify escapes \n to the two characters \ + n, so nothing unsafe can reach a terminal through that path — the collapse only costs stack-trace structure for the agent consumers the PR was written for. Collapsing inside formatLogLine instead of at the fetch boundary keeps the human path safe and the JSON path lossless.

Neither blocks. Four rounds in, this is in good shape — the round 2/3/4 commits addressed the substance of everything raised, and each fix is backed by a test that actually fails when the fix is removed.

[tonychang04]

Addressed the blocking finding in 01f4759: the follow loop now takes the cursor exactly as the server reports it (including null), so a stale token can't survive the cursor-to-no-cursor transition, with a regression test for that sequence.

On the reportCliUsage suggestion: intentionally omitted. DEVELOPMENT.md says verbatim not to use reportCliUsage for new commands — the legacy OSS usage path is being removed — and PostHog trackCommandUsage is the path going forward. The other compute commands carry both only because they predate that rule.

[jwfing]

Summary

compute logs <id> matches the documented backend contract exactly, the round-2/round-3 fixes closed the telemetry, limit-parsing, terminal-escape and follow-resilience gaps, and I found no blocking issue — the remaining items are all about --follow behaviour under load and ordering.

Reviewed at head 7d29de0 (the branch moved twice while I was reading: 51e7e36 → db86956 → 7d29de0, so my earlier notes on reportCliUsage, Number(opts.limit) || 100, unsanitized region/instance, follow-loop death on a 429, and line1line2 glue are all already fixed and are not repeated below).

Requirements context

No matching spec/plan found — this repo has no /docs/superpowers/; its spec directory is docs/specs/, and the three files there (2026-03-27-diagnose-*, 2026-04-17-db-migrations-command-design.md) don't cover compute logs. So I assessed against the PR description, README.md:1094-1103, DEVELOPMENT.md, and — because the PR asserts a wire contract — the actual backend source.

I cloned InsForge/InsForge and verified the contract rather than trusting the PR body:

• backend/src/api/routes/compute/services.routes.ts:653-671 — route is GET /:id/logs, reads req.query.limit and req.query.next_token (snake_case, as the CLI sends), clamps 1-1000 identically, and is guarded by verifyAdmin + a project-ownership check.
• packages/shared-schemas/src/compute-services-api.schema.ts:172-175 — response is { lines: { timestamp: number, message: string, instance?, region? }[], nextToken: string | null }, unwrapped (successResponse is a bare res.json(data)), which is exactly what fetchComputeLogs types and normalizes.
• backend/src/api/middlewares/rate-limiters.ts:106-122 — computeLogsRateLimiter is 120 req/min per IP, so the 2 s follow cadence (~30/min) is comfortably inside it. The PR's claim here checks out.

Verification performed

• npx vitest run src/commands/compute/logs.test.ts → 11 passed at 7d29de0.
• npx eslint on logs.ts, logs.test.ts, integration/compute.test.ts → clean.
• npx tsc --noEmit → zero errors in the touched files (the repo has pre-existing errors in metadata.ts, config/apply.ts, etc.; CI runs npm run lint + npm run build, not tsc, and Lint & Build is green on 7d29de0).
• I drove the registered command through commander with mocked ossFetch and fake timers to exercise the paths the suite doesn't: 401 fail-fast, 5-consecutive-429 give-up, res.json() parse-error fail-fast, out-of-order pages, and same-millisecond arrivals. Results cited inline below.

Findings

Critical

(none)

Suggestion

1. Functionality — --follow caps throughput at limit lines per 2 s, and on the Fly driver the overflow is silently dropped. src/commands/compute/logs.ts:148-179

Each poll fetches at most limit lines and then sleeps FOLLOW_INTERVAL_MS, so the tail can only advance ~50 lines/s at the default --limit 100. What happens to the excess differs by driver, and neither outcome is good:

• Docker driver (backend/src/providers/compute/docker.provider.ts:908-919): the cursor is taken from the returned page, so surplus lines are deferred — but the backlog then grows without bound and the tail never catches up while the app keeps logging.
• Fly driver (backend/src/providers/compute/fly.provider.ts:560-577): bounded = lines.slice(-limit) keeps the newest limit, while nextToken comes from meta.next_token for the whole response. The cursor therefore jumps past lines that were never returned — a container logging faster than limit per poll loses lines mid-tail with no indication.

The loss mechanism lives in the already-merged provider, not in this diff, so this isn't a blocker on the CLI. But the CLI can neutralise it cheaply: when a page comes back full (page.lines.length === limit), poll again immediately instead of sleeping, and only sleep once a short page proves you've drained. That turns "silently lossy under load" into "briefly busy under load".

2. Correctness — the dedupe watermark is read from the last array element, not the maximum, so a page not in ascending order moves it backwards and re-prints. src/commands/compute/logs.ts:168-177

const newTs = fresh[fresh.length - 1].timestamp; then unconditional lastTs = newTs; lastTsKeys.clear();. Round 2 had Math.max(lastTs, …), which couldn't regress; round 3 dropped that guard.

Reproduced (fake timers, cursor-less follow): first page [ts=10], second page [ts=20, ts=15], third page identical to the second. Printed: ten, twenty, fifteen, twenty — twenty emitted twice, because lastTs was set to 15 and the key set was cleared. Both shipped providers emit oldest-first, so this needs a provider ordering change to bite; it's a one-line hardening (Math.max(...fresh.map(l => l.timestamp))) against an assumption that isn't asserted anywhere.

3. Software engineering — the --follow failure policy is the riskiest new logic and is only half covered. src/commands/compute/logs.ts:147-161, src/commands/compute/logs.test.ts:118-131

The new test covers the happy retry (one 429 → recovers), which is the right first case. Not covered, and all cheap to add with the fake-timer harness already in the file:

• fail-fast on a terminal error — I confirmed a 401 aborts after 2 fetches, and an unclassified res.json() SyntaxError also aborts after 2 (correct, and it matches the contract documented on isTransientApiError at src/lib/errors.ts:48-71 — but nothing pins it, so a future widening of that helper would silently make the tail spin on a genuine bug);
• the give-up path — 5 consecutive 429s ends the tail after 6 fetches (~66 s of backoff). That's a user-visible policy number with no test holding it;
• ordering — finding 2 exists precisely because nothing asserts pages are ascending.

Nice reuse of the existing isTransientApiError rather than a bespoke predicate; I verified ossFetch populates statusCode on its HTTP errors (src/lib/api/oss.ts:313) and NETWORK_ERROR_CODE on transport failures (:257), and that TRANSIENT_4XX_STATUSES includes 429 — so the retry branch really is reachable, not decorative.

Information

4. Functionality — an exact-duplicate line in the same millisecond is dropped in the cursor-less fallback. src/commands/compute/logs.ts:142-166
lineKey is instance|message, so a genuinely new line identical to one already printed in the same millisecond is filtered. Reproduced: page 2 containing [tick, tick, other] after tick was printed emits only other. Inherent to content-keyed dedupe without a sequence number, only reachable when the provider stops issuing cursors, and strictly better than the duplicate-spam it replaced — noting it so the tradeoff is a choice rather than a surprise.

5. UX — transient retries are silent. src/commands/compute/logs.ts:154-160
On backoff the tail can stall up to 30 s with nothing on the terminal; a one-line console.error in non-JSON mode (stderr keeps the NDJSON stream clean, as handleError already does) would distinguish "backend is throttling me" from "the app went quiet".

6. parseLimit coercion edges. src/commands/compute/logs.ts:59-63
parseLimit('') → 1 (not the default) and parseLimit('0x10') → 16, both from Number() semantics. Harmless; the documented 1-1000 contract now holds exactly for 0, -7, 2.9, abc, 5000, Infinity, which is what the fix was for.

7. Telemetry — --follow failures are recorded as successes. src/commands/compute/logs.ts:111-114, src/lib/command-telemetry.ts:84-104
The success event fires after the first fetch, before the loop, and trackCommandUsage has a once-per-process outcomeRecorded guard, so the failure event at :182 is suppressed. This is by design (the guard exists to prevent double-emit) and matches compute events; the consequence is that follow-mode failure rates won't be visible in PostHog.

8. Security — no findings. Sanitisation is now applied at the fetch boundary to message, instance and region (:84-89), so both human and --json output are covered — I confirmed an OSC title-set payload and an 8-bit CSI (U+009B) in region/instance are stripped in both modes. The regex's bare-� arm means an unterminated CSI degrades to literal text (x�[123 → x123) rather than leaking a control byte. Service id is encodeURIComponent'd, query built with URLSearchParams, requireAuth() client-side and verifyAdmin + project-scoping server-side, no auth check weakened, no new dependencies. Container logs may contain application secrets, but surfacing them is the feature.

9. Performance — no findings. Pages are capped at 1000, the 2 s cadence sits well under the 120/min limiter, lastTsKeys is bounded by limit and cleared on each timestamp advance, no per-request allocation growth, no blocking work on the event loop. Finding 1 is a throughput/correctness point, not a resource one.

10. Conventions followed. ESM .js import extensions, getRootOpts(cmd) for --json, outputJson, handleError(err, json), registration in src/index.ts:80/278 alongside the sibling compute commands, and trackCommandUsage('compute', 'logs', …) with non-sensitive properties only (result_count, follow) per DEVELOPMENT.md:33-59. The events.ts comment correction and the added src/integration/compute.test.ts:100-112 case bring compute logs to parity with compute events. Diff stays inside its stated scope.

---

Verdict

approved — zero Critical findings. The three Suggestions are non-blocking; finding 1 is the one I'd most like to see land, since it's the difference between a tail that lags and a tail that silently loses lines. Explicit GitHub approval remains a separate human action.

[jwfing]

Summary
No blocking issues found for the new compute logs <id> CLI surface.

Requirements context
I used the PR description, README additions at README.md:1094-1103, the existing compute command conventions, and the public InsForge Compute docs: https://docs.insforge.dev/core-concepts/compute/overview. I also cross-checked the public backend/dashboard contract in InsForge/insforge, which matches GET /api/compute/services/:id/logs with limit, next_token, epoch-ms timestamps, and { lines, nextToken }.

Findings

Critical
(none)

Suggestion
(none)

Information

• src/commands/compute/logs.ts:71-93, src/commands/compute/logs.ts:96-185 — Functionality looks aligned with the PR contract: the service id and cursor are encoded into the expected endpoint, malformed/overflow limits are clamped, non-follow JSON returns { lines, nextToken }, and follow mode advances with the returned cursor.
• src/commands/compute/logs.test.ts:54-165 — Software engineering coverage is solid for the changed behavior: endpoint URL construction, limit clamping, next_token, formatted output, JSON passthrough, follow polling, cursorless dedupe, transient retry, NDJSON, and sanitizer helpers are covered.
• src/commands/compute/logs.ts:37-55, src/commands/compute/logs.ts:84-89, src/commands/compute/logs.ts:106-109 — Security review found no SQL/shell/dependency additions or auth weakening; the command keeps the existing requireAuth/ossFetch path and treats returned log fields as untrusted terminal output.
• src/commands/compute/logs.ts:30-35, src/commands/compute/logs.ts:148-159 — Performance review found no N+1 or unbounded fetch size issue; the command clamps page size and uses the documented 2s polling interval with bounded backoff on transient poll failures.

I did not run local verification commands because node_modules/.bin/{vitest,tsc,eslint} are absent in this read-only checkout, and installing dependencies would modify the workspace.

Verdict
approved — no Critical findings; human maintainers still make the merge/approve call.

Summary

compute logs <id> matches the backend route and the Phase-2 intent exactly, is well tested and correctly hardened against terminal-escape injection; what remains are four non-blocking --follow / robustness items, one of which is a latent backend flaw this PR is the first to expose.

Reviewed at head 7d29de0d (the branch moved twice while earlier reviews were in flight — 5e2168d and 7d29de0d landed after them, so every claim below was re-run against the current tree, with tests installed and executed, not read).

Requirements context

This repo has no /docs/superpowers/. docs/specs/ holds three unrelated designs (diagnose, db-migrations), so no spec in this repo matches this PR. The intent document lives in the InsForge OSS monorepo — .internal/docs/specs/2026-06-04-compute-container-logs-design.md — which closes with:

Non-goals — No CLI in this PR — Phase 2 (compute logs <id> --follow), reusing the same route.

So this PR is the specified Phase 2. I verified the contract against that repo rather than trusting the PR body:

Claim	Verified against
GET /api/compute/services/:id/logs, limit, next_token	backend/src/server.ts:246 (apiRouter.use('/compute/services', …)) + services.routes.ts:646-671 — param names and the 1–1000 server-side clamp match
Response is a bare { lines, nextToken }	successResponse is res.status(…).json(data) (utils/response.ts:22-24), and computeLogsResponseSchema (shared-schemas/src/compute-services-api.schema.ts:160-176) is exactly {lines: {timestamp, message, instance?, region?}[], nextToken: string|null} — the CLI's local interfaces are faithful
"poll every 2s matches the server-side rate limiter"	computeLogsRateLimiter is windowMs 60s / max 120 per IP (api/middlewares/rate-limiters.ts:106-122). 2s polling = 30/min, 4× headroom even alongside an open dashboard tab. Accurate
Auth unchanged	Route is verifyAdmin + project-ownership; the Fly org token never leaves the backend, same boundary as events
DEVELOPMENT.md §3 (new command ⇒ update the insforge-cli skill in the same change set)	Companion PR InsForge/insforge-skills#150 is open ✅

Also verified end-to-end rather than by inspection: npm run build (incl. DTS) succeeds and node dist/index.js compute logs --help renders all three flags — the registration at src/index.ts:277 is genuinely reachable from the real entry point. npx vitest run src/commands/compute/logs.test.ts → 11 passed; npx eslint clean on all changed files. (tsc --noEmit has ~8 pre-existing errors elsewhere in the repo; none in files this PR touches.)

Findings

Critical

(none) — nothing here blocks merge.

Suggestion

1. Functionality — --follow still freezes on a stale cursor and re-prints the same lines every poll (src/commands/compute/logs.ts:162-178)

The comment at :136-141 promises a fallback ("When the provider stops returning a cursor, each poll re-fetches the recent window; drop lines already printed"), but :178 only ever advances the token:

const fresh = token ? page.lines : page.lines.filter(…)   // :162 — tests EXISTENCE
…
if (page.nextToken) token = page.nextToken;               // :178 — null never clears it

Once any cursor has been seen, token is permanently truthy, so the dedupe branch is unreachable and the frozen cursor is re-sent forever. Driven against the real command at 7d29de0d (fake timers, 3 polls after a page with nextToken: null):

urls:    …/logs?limit=100
         …/logs?limit=100&next_token=tokA
         …/logs?limit=100&next_token=tokA   <- frozen
         …/logs?limit=100&next_token=tokA
printed: …001Z  one
         …002Z  two
         …002Z  two
         …002Z  two

Fix is one line plus the condition: keep the token used for the request, set token = page.nextToken unconditionally, and apply the timestamp/key filter whenever the cursor did not advance. A regression test for the cursor→no-cursor transition would pin it (the existing cursorless test at logs.test.ts:98-115 starts with null, so it passes either way).

Severity note / adjudication: an earlier sibling review filed this as Critical. I'm deliberately rating it Suggestion. The trigger (a page carrying lines and a null/empty cursor, after a cursor was already issued) is not reachable through any provider I could confirm: docker.provider.ts:914-921 seeds highest from the incoming watermark so its token can never go back to null, and fly.provider.ts:569-576 only nulls out when Fly returns neither a numeric nor a string next_token, which the OSS unit tests don't exercise. The failure mode is duplicate output in a foreground, Ctrl-C-able tail — new lines still arrive, nothing is lost or corrupted, and no state is written. Real, worth fixing, not merge-blocking.

2. Functionality — with an advancing cursor, --follow can silently drop lines on the Fly self-host path (surfaced by src/commands/compute/logs.ts:152; root cause is fly.provider.ts:558-577 in InsForge OSS)

FlyProvider.getLogs keeps only the newest limit lines (bounded = lines.slice(-limit)) but takes nextToken from meta.next_token of the whole response — i.e. past every line it just discarded. If more than --limit lines land between two polls, the middle of the batch is unreachable by any later request. The Docker driver explicitly avoids this trap (docker.provider.ts:866-872: "tail … drops the middle of a backlog … which no later request can reach") and takes its cursor from the page it actually returned.

This has been dormant because the dashboard never sends a cursor — ServiceLogs.tsx:14-19 re-fetches the recent window on a 2s timer, exactly as the design doc chose ("stateless; no cursor accumulation/dedup to get wrong"). This PR is the first consumer of the cursor path, so it is what makes the flaw user-visible: compute logs --follow on a service logging >100 lines per 2s window will lose lines with no indication. This one is a silent-loss mode, unlike (1).

The real fix belongs in the OSS backend (mirror the Docker driver: return the oldest limit and derive the cursor from the returned page). In this PR, worth at least a README note, or a larger default limit while following.

3. Software engineering — timestamp is the one field the normalizer doesn't harden, and it throws (src/commands/compute/logs.ts:84-89, :65-69)

fetchComputeLogs carefully coerces message, instance and region through String(...)/sanitizeLogMessage, then copies timestamp raw. formatLogLine does new Date(line.timestamp).toISOString(), which throws RangeError: Invalid time value on a missing/NaN value. Reproduced by driving the command with one line lacking timestamp: the whole command aborts with a bare "Invalid time value", and in --follow this happens in print() outside the poll try/catch, so the new retry logic doesn't help.

CloudComputeProvider.getLogs (cloud.provider.ts:246-265) proxies the control plane's JSON verbatim, and the route doesn't validate the response against computeLogsResponseSchema — so a shape drift on the Cloud path reaches the CLI unfiltered. The dashboard already defends against precisely this (ServiceLogs.tsx:63-68: isNaN(d.getTime()) ? String(entry.timestamp) : …). Same treatment here — coerce at the boundary or fall back to the raw value — makes the hardening consistent.

4. Software engineering — the C0 collapse also applies to the --json payload, where it isn't needed (src/commands/compute/logs.ts:49-55, :86)

Moving sanitization to the fetch boundary was the right call for C1 bytes (JSON.stringify does leave those raw). But JSON.stringify does escape \n as \ + n, so a raw newline can never reach a terminal through the JSON path — collapsing it to a space only flattens stack traces for the agent consumer this PR exists for. Keeping \n in the data and collapsing it in formatLogLine (the human path, which is where forged output lines are the actual risk) would be lossless in both modes. The escape/C1 stripping should stay at the boundary either way.

Information

• Do not add reportCliUsage here. A sibling review suggested matching events.ts:38-48. That's wrong for new code: DEVELOPMENT.md:57-60 says verbatim "Do not use reportCliUsage for new commands — that legacy OSS telemetry path has been removed from create, link, and docs. PostHog is the path going forward." The trackCommandUsage('compute','logs',…) call at :111-114 is the correct convention, its properties (result_count number, follow boolean) satisfy the non-sensitive-metadata rule in §2, and flushing is handled inside the helper. Emitting it once before the follow loop is right — a long tail still gets counted.
• lineKey (:142) is instance|message and ignores region; two byte-identical lines from one instance inside the same millisecond dedupe to one. Fine trade-off vs. the bug it fixes — worth a word in the comment.
• --json --follow emits log-line objects only, never nextToken, so an agent tailing as NDJSON can't resume where it stopped; --json without --follow is the resume path. Documented in README.md:1094-1103, just noting the asymmetry.
• parseLimit('') and parseLimit(' ') return 1, not the default — Number('') is 0, which is finite and clamps up. The comment at :57-58 says malformed input falls back to the default. Cosmetic.
• The trackCommandUsage success call is unasserted — deleting it leaves the suite green. Folding expect(trackCommandUsage).toHaveBeenCalledWith('compute','logs',true,…) into an existing case would pin the event name, which DEVELOPMENT.md:44-46 asks to keep stable.

Security — verified, no findings

• The sanitizer is sound as written. TERMINAL_SEQUENCES (:45) ends in a bare |� arm and includes [�-�], so after one pass no ESC and no C1 byte can survive — which also closes the "removing a sequence re-forms a new one" reassembly trick, since there is nothing left to re-form from. CONTROL_RUNS then collapses remaining C0 (tab preserved). Applying it in fetchComputeLogs covers --json too, and 7d29de0d correctly extended it to region/instance, which land on the same rendered line.
• Service id is encodeURIComponent-ed into the path; next_token goes through URLSearchParams. No SQL, no shell, no new dependencies. requireAuth() retained, and the backend still enforces verifyAdmin + project-ownership — no authz path is weakened. Nothing secret is logged or added to telemetry.

Performance — verified, one finding (item 2 above)

2s polling sits at 25% of the server limiter; transient 429/5xx/network failures back off exponentially to a 30s cap and give up after 5 consecutive misses (:147-161) — classification confirmed correct: ossFetch throws CLIError carrying statusCode (lib/api/oss.ts:313) and tags transport failures NETWORK_ERROR (:257), and isTransientApiError (lib/errors.ts:72-77) admits 5xx + {408,429} only, so the limiter's 429 retries while 401/403/404 fail fast. Follow-mode state is bounded (one timestamp plus the key set for a single millisecond, cleared on each advance) — no accumulation across a long tail, no blocking I/O, no N+1.

Verdict

approved — zero Critical findings. Items 1–4 are all worth addressing (1 and 3 are cheap and self-contained; 2 needs a companion fix in InsForge OSS), but none of them justifies blocking. Informational — the GitHub green check remains a separate human action.

[jwfing]

Summary
The PR implements the intended container stdout/stderr CLI surface with no critical findings; one cursorless-follow edge case is worth tightening.

Requirements context
I derived intent from the PR description for InsForge/CLI#287, the prior rename context in InsForge/CLI#96, the companion skills PR InsForge/insforge-skills#150, and the new README section at README.md:1094-1103. The requirement is to expose compute logs <id> for container application logs via GET /api/compute/services/:id/logs, support --limit, --next-token, --follow, and --json, while leaving compute events for lifecycle events.

Findings

Critical

(none)

Suggestion

• src/commands/compute/logs.ts:142-166 — In the cursorless follow fallback, dedupe uses a Set keyed by instance|message, so repeated identical messages from the same instance at the boundary timestamp are all filtered once that key has been seen. This can drop real duplicate log lines if the backend returns overlapping windows without a cursor. Consider tracking counts per boundary key, and including region in the key, so only the already-printed occurrences are suppressed.

Information

• src/commands/compute/logs.test.ts:54-185 — Software engineering/test coverage looks appropriate for this change: URL encoding, limit clamping, cursor forwarding, text formatting, JSON output, follow polling, stale-cursor behavior, transient retry, and sanitizer behavior are covered.
• src/commands/compute/logs.ts:75-89 and src/commands/compute/logs.ts:105-109 — Security review found no new auth or injection issue: the command requires auth, uses the existing ossFetch path, URL-encodes path/query input, adds no dependency, and sanitizes printable log fields before output.
• src/commands/compute/logs.ts:59-62 and src/commands/compute/logs.ts:148-160 — Performance review found no blocking concern: fetch size is clamped to 1-1000, follow mode is intentionally long-running, and transient retry backs off with a cap.

Verdict
Approved per the requested rule: there are no Critical findings. I did not run the test suite to keep the review read-only; git diff --check main...HEAD produced no whitespace errors.

Addendum — re-verified at 6b0dcea7

My review above was written against 7d29de0d; 01f4759b and 6b0dcea7 landed while it was posting (GitHub attached it to 6b0dcea7). Re-checked the moved code with deps installed and tests run.

Suggestion 1 (frozen cursor) — fixed, verified

logs.ts:164-166 now filters every poll, and :179 takes the cursor as reported including null. My reproduction from the review no longer reprints: the batch that used to appear 3× appears once, and the stale token is dropped rather than re-sent. Both halves are pinned by new tests (logs.test.ts:118-153), and the suite is 13 passed / eslint clean at this head. Suggestions 2 (Fly slice(-limit) cursor skip), 3 (timestamp unhardened → RangeError) and 4 (--json newline collapse) are untouched by these commits and still stand as written.

One consequence of the new unconditional filter — Suggestion

A cursor page carrying a line older than the newest already printed is now silently dropped (src/commands/compute/logs.ts:164-166)

Before 6b0dcea7, cursor-advancing pages passed through untouched; now they go through l.timestamp > lastTs || (=== lastTs && !seen). The comment at :141-143 justifies this with "ordinary advancing pages carry strictly newer timestamps" — which holds for well-formed pages, but not for the one case the backend deliberately manufactures: fly.provider.ts:551 normalizes an unparseable RFC3339 timestamp to 0. Such a line now never prints. Driven at 6b0dcea7 — page 2 = [{ts: 0, "UNPARSEABLE-TS-LINE"}, {ts: 1001, "later"}] after a printed line at ts: 1000:

printed: …01.000Z  first
         …01.001Z  later      <- the ts=0 line is gone, no indication

Same shape for any provider that returns a page out of order. Cheap guard: only apply the filter when the cursor did not advance (page.nextToken === tokenUsedForThisRequest), which is the condition the dedupe actually exists for — that keeps the frozen-cursor fix and stops filtering pages that are genuinely new.

Information

• The keyed dedupe also suppresses a genuinely repeated identical line inside one millisecond, and as of this commit it does so in cursor mode too. Verified: two polls each returning {ts: 7, "retrying connect"} print one line. A tight retry loop logging the same string is the realistic case. Acceptable — the alternative is the duplicate flood — but lineKey (:144) ignoring region and carrying no occurrence count is worth a note in that comment.

Verdict (unchanged)

approved — still zero Critical. The item above is a narrow edge introduced by an otherwise-correct fix, and the fix it came with removed the more likely defect. Informational — the GitHub green check remains a separate human action.

Guard against non-object elements in body.lines.

Array.isArray(body?.lines) accepts an array whose elements are null. The mapper then reads l.timestamp, which throws TypeError: Cannot read properties of null. The body is an open network record, so this shape is reachable, and the malformed-body test only covers body === null. In follow mode the error is not transient, so the loop rethrows and the tail ends.

Filter to object elements before mapping.

🛡️ Proposed fix

-  const lines = (Array.isArray(body?.lines) ? body.lines : []).map((l): ComputeLogLine => ({
+  const raw = Array.isArray(body?.lines) ? body.lines : [];
+  const lines = raw.filter((l): l is ComputeLogLine => typeof l === 'object' && l !== null).map((l): ComputeLogLine => ({

Summary

The command is well-scoped and mostly matches the requested CLI surface, but the log sanitizer has a blocking terminal-injection bug.

Requirements context

I reviewed the PR description, the added README docs at README.md:1094-1102, the CLI development guide at DEVELOPMENT.md:13-27, and the prior rename context in InsForge/CLI#96. I also checked the public Compute docs, which describe container logs as tail-able from dashboard/CLI/MCP, and the current backend route/interface showing GET /api/compute/services/:id/logs with limit and next_token: Compute docs, backend route, provider interface.

Findings

Critical

• src/commands/compute/logs.ts:48-57 - TERMINAL_SEQUENCES is missing the global flag, so sanitizeLogMessage() removes only the first terminal sequence. Subsequent ESC-led sequences are only partially defanged into visible artifacts, and subsequent C1 controls are left intact because CONTROL_RUNS only covers C0/DEL. This matters because container stdout/stderr is untrusted and printed in both formatted and NDJSON modes; for example, a harmless first ANSI sequence can be followed by a C1 CSI clear-screen sequence that survives sanitization. Make the terminal-sequence regex global and add a regression that includes multiple escape/C1 sequences in one message. This also contradicts the intended multi-sequence test at src/commands/compute/logs.test.ts:303-313.

Suggestion

• (none)

Information

• src/commands/compute/logs.ts:109-143, src/index.ts:270-280 - Software engineering: command registration, ossFetch, root --json, and telemetry shape are consistent with the local CLI command patterns.
• src/commands/compute/logs.ts:60-67, src/commands/compute/logs.ts:207-219 - Performance: page size is clamped to 1-1000, follow mode polls serially every 2s, and transient failures back off; no performance-relevant blocker found.
• src/commands/compute/logs.test.ts:56-276, src/integration/compute.test.ts:100-110 - Test coverage is broad for the new behavior, but I could not run it locally because npx vitest run src/commands/compute/logs.test.ts failed at startup with Cannot find package 'vitest' imported from vitest.config.ts.

Verdict

Request changes. The feature should not ship until the sanitizer strips all terminal-control sequences, not just the first one.

[jwfing]

Summary

Re-review at head cd3bb32 (fix(compute-logs): guard the follow watermark against NaN, future, and backward moves). The new guard fixes the watermark-poisoning case I raised at bd25fde, but it fixes it in the max only — an implausible timestamp is now excluded from the watermark while nothing suppresses the line itself, so it reprints on every poll. No Critical findings; the harm direction is duplication, never loss (verified below), so this stays non-blocking.

Requirements context

This repo has no /docs/superpowers/, and docs/specs/ holds only the diagnose and db-migrations designs — nothing matching compute logs. The design doc for this feature lives in the sibling repo: InsForge/InsForge → .internal/docs/specs/2026-06-04-compute-container-logs-design.md, whose Non-goals explicitly sanction this PR as Phase 2 ("No CLI in this PR — Phase 2 (compute logs <id> --follow)"). Assessed against that doc plus the PR body.

Verification for this round, in a clean npm ci checkout of cd3bb32: npx vitest run src/commands/compute/logs.test.ts → 23/23 green; eslint clean; tsc --noEmit reports no errors in this PR's paths (the repo has pre-existing errors elsewhere).

Findings

Critical

(none)

Suggestion

1. functionality — the plausibility bound is measured against the client's clock, so a skewed client turns --follow into an infinite reprint loop (src/commands/compute/logs.ts:175-180)

maxTs now rejects any l.timestamp > Date.now() + CLOCK_SKEW_MS. That stops such a line pinning the watermark — but nothing else in the loop suppresses it, because it is neither < lastTs nor === lastTs, so it goes into fresh on every non-advancing poll.

Two triggers, both reproduced against this head with the author's own harness (fake timers, vi.setSystemTime):

• P1 — client clock 10 min behind the provider, null cursor, static window. maxTs rejects every line, lastTs stays 0, lastTsCounts stays empty, and the whole window is re-emitted each poll. One line, 5 polls → printed 6×. With --limit 1000 that is the entire window re-dumped every 2 s.
• P3 — one year-2100 line inside an otherwise normal window. The real lines dedupe correctly; the future line is printed 6× over the same 5 polls.

Both probes pass at bd25fde and fail at cd3bb32 — this is a regression from the newest commit, not a pre-existing gap. Worth stating plainly: the direction of harm is only duplication. I checked the loss direction explicitly — when every line is rejected the watermark sits at 0, so nothing is ever dropped. That is why this is Suggestion and not a repeat of the round-6 Critical. The half I could not demonstrate is incidence: I can show the behaviour deterministically, but not how often a ≥5-minute client-vs-provider skew occurs against real Fly/docker providers.

Fix I ran end-to-end — route an implausible timestamp into the undated dedupe that already exists, instead of only excluding it from the max:

const usableTs = (t: number) => Number.isFinite(t) && t > 0 && t <= Date.now() + CLOCK_SKEW_MS;
const maxTs = (lines: ComputeLogLine[]) =>
  lines.reduce((m, l) => (usableTs(l.timestamp) && l.timestamp > m ? l.timestamp : m), 0);

then swap the two Number.isFinite(l.timestamp) tests at logs.ts:199 and logs.ts:233 for usableTs(l.timestamp). Result: 23/23 of your tests stay green and all three of my probes go green — including the new --follow ignores an implausibly future timestamp test, which still passes because an unusable line is now printed exactly once rather than repeatedly.

2. functionality — the 0 half of the "0/NaN" sentinel is still unhandled (src/commands/compute/logs.ts:192-204, guard at :199/:233)

The comment states "the Fly driver maps an unparseable one to 0/NaN", but the guard is Number.isFinite, which is true for 0. So a genuinely new line carrying the Fly 0 sentinel hits if (l.timestamp < lastTs) continue at :243 and is dropped silently, forever, on any non-advancing-cursor poll.

• P2 — first page [{ts: T, 'old'}], then a re-sent window [{ts: T, 'old'}, {ts: 0, 'sentinel-new'}]: sentinel-new printed 0× across 3 polls. Fails at bd25fde too, so pre-existing rather than new. The t > 0 clause in the usableTs above closes it in the same edit — it routes the sentinel through the undated occurrence-count path, which prints it once and dedupes the re-sends.

3. software engineering — the two new tests only cover the loss direction (src/commands/compute/logs.test.ts:217-244)

--follow ignores an implausibly future timestamp asserts the later real line still prints; nothing asserts the implausible line stops printing. That is exactly the gap finding #1 fell through, and it is the same one-directional-predicate pattern that produced the earlier rounds' regressions. A single test — poll a static window 5× with a null cursor and assert every message appears exactly once — would have caught #1 and #2 together, and would keep catching them if the watermark is touched again.

4. software engineering — timestamp is the one field fetchComputeLogs still passes through uncoerced (src/commands/compute/logs.ts:97-102)

The new comment at :92-96 documents this as deliberate, and the reasoning (an unusable timestamp must stay distinguishable from a genuine 0) is sound. The residual is that "unusable" is not single-valued: a string timestamp survives to the loop, where Number.isFinite('1700000000000') is false, so a perfectly good numeric-string timestamp is treated as undated. timestamp: typeof l.timestamp === 'number' ? l.timestamp : NaN at :98 would normalise the bad cases to one representation and compose with #1/#2.

Information

5. performance — Date.now() is called per line inside the reduce (src/commands/compute/logs.ts:176). Up to 1000 calls per poll, and the bound is not constant within a single page. Hoisting one const now = Date.now() per maxTs call is both cheaper and more correct.

6. maxTs seeds at 0 and only accepts l.timestamp > m, so a negative timestamp can never become the watermark. Harmless today, and consistent with the t > 0 clause suggested above.

7. security — no security-relevant change in this round. Sanitisation still happens at the fetch boundary (logs.ts:48-58, :97-102) so --json is covered, requireAuth() is unchanged, no new dependencies, and nothing new is logged or returned that carries credentials. The new fetchComputeLogs boundary tests (logs.test.ts:280-301) are a welcome addition — they pin the sanitisation contract and the empty-cursor→null normalisation.

8. performance — nothing else to flag. The 2 s interval matches the server-side limiter, --limit is hard-clamped to 1000, and the per-poll allocations are two Map copies bounded by that limit.

9. prior blocking reviews adjudicated. The two outstanding CHANGES_REQUESTED states (5045943194 against 6bbdf43, 5045978091 whose body analyses 6bbdf43 despite being bound to 525a8b7) both concern the advancing-cursor dedupe. 525a8b7 shipped the cursorAdvanced gate and I re-verified at this head that an advancing page prints verbatim — those are resolved and should not be read as blocking cd3bb32.

Verdict

approved — 0 Critical findings. Findings #1 and #2 are worth a follow-up commit (one usableTs helper closes both, with your suite staying green), but neither loses log lines, so they do not block. Informational only; a human still gives the GitHub approval.

[jwfing]

LGTM - approved.

[jwfing]

Addendum — head moved to 2cb375d during my post

My review above analysed cd3bb32; GitHub bound it to 2cb375d (fix(compute-logs): treat implausibly future timestamps as undated everywhere), which landed while I was posting. Re-verified against the new head so nothing above is read as stale.

Finding #1 is fixed. 2cb375d introduces positionable() at src/commands/compute/logs.ts:178 and applies it in maxTs, in undatedCounts (:203), and at the dedupe branch (:237) — the same shape I proposed. Re-ran at this head:

probe	cd3bb32	2cb375d
P1 — client clock 10 min behind, static window, 5 polls	printed 6×	printed 1× ✅
P3 — year-2100 line in a normal window, 5 polls	printed 6×	printed 1× ✅
P2 — Fly ts: 0 sentinel on a new line	printed 0×	printed 0× ❌ still open

Author suite at 2cb375d: 24/24 green (the new --follow test for a future timestamp on a re-sent window is a good addition, and it closes the one-directional-test gap I raised as finding #3 for this predicate).

Finding #2 is still live, and it is now a one-word delta. positionable is Number.isFinite(ts) && ts <= Date.now() + CLOCK_SKEW_MS — no lower bound, and Number.isFinite(0) is true. The comment at logs.ts:196-199 still says the Fly driver maps an unparseable timestamp "to 0/NaN", so the 0 half continues to fall into the dated path and gets dropped at if (l.timestamp < lastTs) continue. Adding ts > 0 to positionable makes P2 pass and keeps all 24 of your tests green (I ran exactly that combination).

Findings #4–#6 (uncoerced/string timestamp, per-line Date.now() inside the reduce, negative timestamps) are unchanged at this head. Verdict is unchanged: approved, 0 Critical.

[jwfing]

Summary

Re-review at 2cb375d — the previously-blocking advancing-cursor bug is genuinely fixed, but the two newest commits (cd3bb32, 2cb375d) introduced a dependency on the client's wall clock that silently kills the follow tail on any machine whose clock is ≥5 minutes slow.

Head moved twice while I was reviewing: bd25fde → cd3bb32 → 2cb375d. Everything below is against 2cb375d; I re-ran all probes after each move.

Requirements context

This repo has no /docs/superpowers/. CLI's own docs/specs/ holds three unrelated designs (diagnose, db-migrations). The intent doc lives in the backend repo: InsForge/InsForge → .internal/docs/specs/2026-06-04-compute-container-logs-design.md (verified still present). Its non-goals sanction this work explicitly:

"No CLI in this PR — Phase 2 (compute logs <id> --follow), reusing the same route."

So the PR is exactly the sanctioned Phase 2 and stays in scope. The same spec flags the hazard this PR keeps re-encountering — the dashboard's v1 tail is "stateless; no cursor accumulation/dedup to get wrong" — and this CLI is the first consumer of the cursor.

Adjudicating the open reviews

Both outstanding CHANGES_REQUESTED (5045943194, 5045978091) are resolved — they are the advancing-cursor dead-tail, fixed by the cursorAdvanced gate in 525a8b7 (logs.ts:222-230). I confirmed with a negative control at this head: deleting the gate turns exactly the advancing-cursor tests red while frozen/null suppression stays green. They can be dismissed.

The Suggestions from review 5046062945 and cubic (NaN-poisoned watermark, future-pinned watermark, backward-moving watermark, no fetch-boundary test) are all addressed by cd3bb32/2cb375d. I negative-controlled the two new guards individually and each is pinned by a dedicated test — reverting newTs > lastTs → !== reddens "does not reprint dated lines when a page also carries an undated one", and dropping the future bound reddens "ignores an implausibly future timestamp". Good, load-bearing tests.

Findings

Critical

1. functionality — a slow client clock turns --follow into a silent dead tail (src/commands/compute/logs.ts:180, used at :182, :203, :237)

const positionable = (ts: number) => Number.isFinite(ts) && ts <= Date.now() + CLOCK_SKEW_MS;

Date.now() is the reader's clock; ts is the provider's. If the operator's machine is more than CLOCK_SKEW_MS (5 min) behind, every legitimate timestamp fails positionable, and since 2cb375d routes non-positionable lines through the undated path in all three places, the entire tail falls back to content-only dedupe — no watermark at all.

Content-only dedupe cannot distinguish a re-sent line from a genuine repeat, which is the exact reasoning in the comment at :220-230. On a scrolling recent-window (null cursor — the dashboard-parity path), a repeated identical message therefore stops printing once the window fills, and never recovers: prevUndated is rebuilt from each page, so N copies in the page are always suppressed by N copies from the previous page.

Reproduced against 2cb375d with the only variable being the client clock — identical server responses, a crash loop emitting one EADDRINUSE, retrying per poll into a 3-line window:

client clock	lines printed over 6 polls
correct	8 ✅ (3 initial + 1 per poll)
10 min slow	3, then silent forever ❌

That is the same dead-tail shape that was blocking at 6bbdf43 — -f on a crash loop, which is why you run -f — now hidden behind an environmental precondition instead of a data one. It is silent in both directions: no warning is printed, and the operator reasonably concludes their app stopped logging. Clock skew of this size is not exotic (a laptop resumed from long sleep before NTP re-syncs, a paused VM, a container host).

The root cause is using the local wall clock as the reference at all. A page-scoped predicate fixes it — if nothing the server sent is plausible, the disagreement is with our clock, not the data:

const positionableFor = (lines: ComputeLogLine[]) => {
  const bound = Date.now() + CLOCK_SKEW_MS;
  const clockTrusted = lines.some((l) => Number.isFinite(l.timestamp) && l.timestamp <= bound);
  return (ts: number) => Number.isFinite(ts) && (!clockTrusted || ts <= bound);
};
let positionable = positionableFor(result.lines);
// ...and re-scope per poll, before first use:
positionable = positionableFor(page.lines);

A single year-2100 line still lands as undated (the rest of its page is plausible, so clockTrusted holds) — your two new guard tests keep passing. Verified at 2cb375d: 24/24 of your tests green, both my clock probes green (8 printed, matching the control), eslint clean, no new tsc errors.

Suggestion

2. functionality — --json output loses newline structure (src/commands/compute/logs.ts:57, applied at :99)

sanitizeLogMessage collapses C0 runs to a space at the fetch boundary, so it also rewrites --json / NDJSON payloads. Stripping escape sequences there is right; collapsing newlines is a terminal-rendering concern, and JSON has no such problem (JSON.stringify escapes \n safely). Your own comment at :53-55 names the case — "a multi-line message (a stack trace delivered as a single entry)" — and that is precisely the payload an agent most needs intact. Verified:

in : "Error: boom\n    at foo (a.js:1)\n    at bar (b.js:2)"
out: "Error: boom     at foo (a.js:1)     at bar (b.js:2)"

Since the PR's stated point of --json is agent consumption, consider keeping TERMINAL_SEQUENCES at the boundary and moving the CONTROL_RUNS collapse into formatLogLine.

3. security — timestamp is the one printable field that bypasses the sanitizer (src/commands/compute/logs.ts:73-74, boundary at :92-98)

fetchComputeLogs sanitizes message, region and instance, and cd3bb32 made the raw timestamp pass-through deliberate. But formatLogLine's fallback prints that raw value verbatim:

const ts = Number.isNaN(d.getTime()) ? String(line.timestamp) : d.toISOString();

Verified — a non-numeric timestamp reaches the terminal with its escapes intact:

formatLogLine({timestamp: "<ESC>]0;PWNED<BEL><ESC>[31m", message: "hi"})
  => "�]0;PWNED��[31m  hi"

Reachability caveat, stated plainly: I could not demonstrate this end-to-end. Both providers normalize before responding — fly.provider.ts:551-553 maps to a number with a 0 fallback, docker.provider.ts:903 uses parsed.ms — so no non-numeric timestamp reaches the CLI today. This is defense-in-depth on a boundary the PR deliberately designed to be complete, and the fix is sanitizeLogMessage(String(line.timestamp)).

4. software engineering — no test exercises a client/server clock disagreement

Coverage is otherwise strong (24 tests, both directions of the cursorAdvanced predicate, both new watermark guards NC-verified, fetch-boundary contract, retry/backoff, NDJSON). The gap is that every test runs under fake timers with Date.now() ≈ 0 and log timestamps near 0, so the Date.now() + CLOCK_SKEW_MS comparison is only ever exercised in the "our clock agrees" direction — which is why finding #1 landed silently. A vi.setSystemTime(logTs - 10 * 60 * 1000) case would pin it.

Information

• functionality — parseLimit(' ') returns 1, not the default 100 (logs.ts:63-67): Number(' ') is 0, which clamps up. events.ts:23 uses Number(opts.limit) || 50, which does fall back for whitespace, so the two compute commands diverge. raw.trim() === '' covers it. (Seconding review 5046062945.)
• functionality — telemetry latches success: true before the tail starts (logs.ts:127-135 + command-telemetry.ts:103-104), so a follow run that later dies on 5 consecutive poll failures still reports success. A deliberate consequence of not blocking the tail on the PostHog flush — flagging only so the dashboards aren't read as clean.
• software engineering — Number.isFinite(l.timestamp) inside maxTs is redundant: l.timestamp > m already rejects NaN/undefined/null for any m >= 0. Removing it keeps the suite green. Harmless belt-and-braces; noting it so the comment isn't read as the load-bearing part.
• backend, pre-existing, not this PR — fly.provider.ts:562 keeps lines.slice(-limit) while taking next_token from the whole response, so a burst larger than limit skips its middle server-side; docker.provider.ts:866-873 documents and avoids the same trap. Invisible while the dashboard never sends next_token; this CLI is the first cursor consumer. Worth a follow-up issue against the OSS repo.
• src/lib/cloudflare.test.ts fails in the full suite — pre-existing, fails identically on main, untouched here.

---

Dimension coverage

• Software engineering — 24 tests, lint clean, 12 repo-wide tsc errors of which 0 are in touched files (the PR body's "tsc clean for touched files" checks out). Uses trackCommandUsage, not the banned reportCliUsage (DEVELOPMENT.md:57-60) ✅. Companion skills PR present per DEVELOPMENT.md §3 ✅. One coverage gap (#4).
• Functionality — the cursor/dedupe logic is correct for advancing, frozen and null cursors when the client clock is right; #1 is the remaining hole.
• Security — no new dependencies; requireAuth() retained; encodeURIComponent on the service id; escape-sequence sanitization at the fetch boundary covering --json (the right layer — JSON.stringify emits C1 bytes raw); telemetry carries only result_count/follow, no log content, matching DEVELOPMENT.md's rule. No auth path weakened. One defense-in-depth gap (#3). Not stripped: Unicode bidi overrides (U+202E) — low value next to the escape work already done.
• Performance — per-poll work is O(page) bounded by limit ≤ 1000 (suppress, undatedSuppress, maxTs); 2s interval matches the server-side limiter tuned for the dashboard; capped exponential backoff on transient failures; no blocking I/O on the event loop, no new DB queries or indexes.

---

Verdict

request_changes — one Critical (#1). Everything else is non-blocking.

To be clear about what changed: cd3bb32 and 2cb375d correctly fixed all four Suggestions from the previous round, and the guards you added are properly tested. The Critical is a side effect of the reference point those guards chose, not a regression in the dedupe logic itself — and the page-scoped predicate above resolves it while keeping every one of your tests green.

[jwfing]

Summary
No Critical issues found; the new compute logs <id> command is aligned with the documented container stdout/stderr logs surface.

Requirements Context
I based the intent on the PR description for InsForge/CLI#287, the new README docs at README.md:1094-1102, the earlier rename that freed compute logs for real container logs in InsForge/CLI#96, and the backend logs endpoint contract from InsForge/InsForge#1480. The repo docs also describe Custom Compute logs as tail-able from dashboard, CLI, or MCP: https://docs.insforge.dev/core-concepts/compute/overview.

Findings

Critical
(none)

Suggestion

• src/commands/compute/logs.ts:97-101 Consider hardening fetchComputeLogs against malformed array elements, not just malformed top-level bodies. If body.lines is an array containing null or a primitive, reading l.timestamp throws before the command can normalize to an empty/safe shape. This is non-blocking because the backend provider contract returns structured { timestamp, message, instance?, region? } objects, but it would make the boundary normalization fully defensive.

Information

• src/commands/compute/logs.ts:83-87, src/commands/compute/logs.ts:121-138, src/index.ts:75-83, src/index.ts:270-280: Functionality and command wiring match the stated API: service IDs are encoded, limit and next_token are sent correctly, non-follow --json returns { lines, nextToken }, and the command is registered under compute.
• src/commands/compute/logs.test.ts:56-350: Software engineering/test coverage is strong for this surface, including endpoint construction, limit parsing, next-token forwarding, formatting, JSON passthrough, follow cursor handling, dedupe behavior, sanitization, and transient retry handling.
• src/commands/compute/logs.ts:47-57, src/commands/compute/logs.ts:97-105, src/commands/compute/logs.ts:130-133: Security review found no blocking issue. The command uses authenticated ossFetch, avoids logging free-text service IDs or messages in telemetry, URL-encodes user-controlled request parts, and strips terminal control sequences from log fields before plain-text and JSON output.
• src/commands/compute/logs.ts:30-38, src/commands/compute/logs.ts:180-223: Performance review found no blocking issue. The fetch size is capped at 1000, follow polling is fixed at the documented 2s cadence with bounded retry backoff, and per-poll dedupe state is bounded by the returned page size.

Verdict
No Critical findings, so the rubric verdict is approved. Per the team rule, this should be posted as a bot comment rather than a GitHub green-check approval. Local tsc, eslint, and focused Vitest verification could not run because the dependency binaries are not installed in this checkout.

[jwfing]

Summary
No blocking issues found; the new compute logs surface is consistent with the PR intent and existing CLI patterns.

Requirements Context
I used the PR description as the primary spec: add compute logs <id> for container stdout/stderr, with --limit, --follow, --next-token, non-follow JSON { lines, nextToken }, and follow-mode NDJSON. The repo README now documents the same behavior at README.md:1094-1102, and the updated compute events comment distinguishes lifecycle events from application logs at src/commands/compute/events.ts:9-12. I did not find local docs for the referenced #96/#662/#1480 items beyond the PR text; public InsForge Compute docs also describe per-container logs as tail-able from dashboard, CLI, or MCP: https://docs.insforge.dev/core-concepts/compute/overview.

Findings

Critical
(none)

Suggestion
(none)

Information

• Software engineering: the command follows the repo’s command registration, ESM import, auth, JSON, and telemetry conventions, and is wired through the compute group at src/index.ts:75-83 and src/index.ts:270-280.
• Functionality: the implementation URL-encodes the service id, clamps --limit to 1-1000, forwards --next-token as next_token, emits full JSON for non-follow mode, and uses NDJSON in follow mode at src/commands/compute/logs.ts:60-66, src/commands/compute/logs.ts:79-145, and src/commands/compute/logs.ts:153-282.
• Security: no security-relevant regression found; the command requires auth, avoids shell/SQL use, encodes URL inputs, sends only count/follow telemetry, and strips terminal control sequences from printable log fields at src/commands/compute/logs.ts:40-57, src/commands/compute/logs.ts:83-105, and src/commands/compute/logs.ts:118-134.
• Performance: no performance concern found; fetches are bounded by the clamped limit and follow mode uses 2s polling with capped transient-error backoff and O(limit) per-page dedupe state at src/commands/compute/logs.ts:30-38, src/commands/compute/logs.ts:60-66, and src/commands/compute/logs.ts:211-260.
• Tests: unit coverage exercises endpoint construction, limit clamp, cursor forwarding, formatting, JSON passthrough, sanitizer behavior, follow cursor/dedupe cases, and transient retry behavior at src/commands/compute/logs.test.ts:56-350; integration coverage checks the real JSON shape at src/integration/compute.test.ts:100-110.

Verdict
Approved per the requested rubric: zero Critical findings. This is a bot review verdict, not a GitHub green-check approval. Local verification was limited to read-only inspection because node_modules is absent and installing dependencies would modify the workspace.

Summary
The new compute logs command is consistent with the PR intent and existing CLI patterns, with no blocking findings.

Requirements Context
I used the PR title/description, the new README section at README.md:1094-1103, the updated distinction from compute events in src/commands/compute/events.ts:9-12, and the repo’s CLI conventions in DEVELOPMENT.md. The intended behavior is: compute logs <id> calls GET /api/compute/services/:id/logs, supports --limit, --next-token, --follow, root --json, and distinguishes application stdout/stderr from machine lifecycle events.

Findings
Critical:
(none)

Suggestion:
(none)

Information:
(none)

Dimension Coverage
Software engineering: command registration, ESM import style, ossFetch, root --json, and telemetry usage fit the surrounding compute command conventions; unit and integration tests cover endpoint construction, limit handling, cursor forwarding, formatting, JSON output, follow behavior, transient errors, and sanitization.

Functionality: the implementation matches the stated CLI surface and README examples, including NDJSON in --json --follow mode and cursor-based polling.

Security: no auth weakening or new dependency risk found; the command uses existing authenticated ossFetch and sanitizes untrusted log fields before both human and JSON output.

Performance: no N+1 or unbounded data fetch found; polling is fixed at 2s, per-page work is bounded by the clamped 1-1000 limit, and follow-mode retry backoff is capped.

Verdict
Approved per the requested rubric: zero Critical findings. I did not run tests because this review was explicitly read-only.

Summary

Re-review at 1b94f6f — my previous blocking finding (a slow client clock dead-tailing --follow) is genuinely fixed and pinned by a load-bearing test; no Critical findings remain, though the new per-page bound re-opens the mirror of the year-2100 watermark bug for a narrower input class.

Head verified with git ls-remote immediately before posting: 1b94f6f4f2cc7b98a64e320e8a08be55e0344f4b. All probes below were run against a fresh npm ci checkout of that commit.

Requirements context

This repo has no /docs/superpowers/. CLI's own docs/specs/ holds three unrelated designs (diagnose, db-migrations) — nothing matching container logs. The intent doc lives in the backend repo: InsForge/InsForge → .internal/docs/specs/2026-06-04-compute-container-logs-design.md (verified present on main). Its Non-goals sanction this work explicitly:

"No CLI in this PR — Phase 2 (compute logs <id> --follow), reusing the same route."

So the PR is exactly the sanctioned Phase 2 and is in scope. I also re-verified the wire contract against backend main rather than assuming it:

• services.routes.ts:653-669 — GET /:id/logs, query limit + next_token, and successResponse (backend/src/utils/response.ts:22-24) is a bare res.json(data) passthrough — no { data: … } envelope, so body.lines / body.nextToken at logs.ts:97-102 is correct.
• compute.provider.ts:76-92 — timestamp is epoch milliseconds (number), nextToken is string | null. The CLI's ComputeLogLine matches field-for-field.

The spec also names the hazard this PR keeps re-encountering — the dashboard's v1 tail is "stateless; no cursor accumulation/dedup to get wrong" — and this CLI is the first consumer of the cursor path.

Adjudicating the open reviews

Two CHANGES_REQUESTED are still open on this PR. Both are resolved at this head and can be dismissed:

• 5046152670 (mine, at 2cb375d) — "a slow client clock turns --follow into a silent dead tail". Fixed by 1b94f6f (logs.ts:189-193, re-scoped per poll at :240). Negative-controlled: reverting positionableFor to the global 2cb375d bound reddens exactly one test — "--follow keeps tailing when the local clock is far behind the provider" — and nothing else. That is a genuinely load-bearing regression test.
• 5046119003 (at cd3bb32) — "TERMINAL_SEQUENCES is missing the global flag, so only the first sequence is stripped". Not reproducible. git show cd3bb32:src/commands/compute/logs.ts line 48 already ends in /g, as does line 48 at this head. Driving the real regex from source over a multi-sequence payload:

  input : ESC[31m a ESC[2J b C1 2J c
  output: "ab2Jc"          # every ESC-led sequence and the C1 introducer removed
  input : ESC]0;pwn BEL x
  output: "x"
  

  The sanitizer is correct; that Critical should not block.

Suggestion

1. functionality — a poll page in which every line is implausibly future re-pins the watermark and permanently kills the tail (src/commands/compute/logs.ts:189-193, consumed at :195-198, :263)

const clockTrusted = lines.some((l) => Number.isFinite(l.timestamp) && l.timestamp <= bound);
return (ts: number) => Number.isFinite(ts) && (!clockTrusted || ts <= bound);

clockTrusted is computed per page, so a page with no plausible line disables the future bound entirely and lets a bogus timestamp become positionable — which is precisely the state cd3bb32 was written to prevent. The existing guard test (logs.test.ts, "ignores an implausibly future timestamp when advancing the watermark") passes only because its page is mixed ({ts: 1000, 'real'} alongside the year-2100 line), so clockTrusted is true there. A uniform page slips straight through.

Verified probe (fake timers, correct client clock; one poll returns only a future-dated line, then five polls each carry a genuinely new correctly-dated line):

printed = ["…  real-1", "…  bogus-future"]     ← 4 subsequent real lines: 0 printed, forever

A/B across the last four heads, same probe:

head	result
bd25fde	✗ dead tail (no bound at all — the original finding)
cd3bb32	✓ guarded
2cb375d	✓ guarded
1b94f6f	✗ dead tail again

So this is a partial regression of cd3bb32, not a pre-existing gap.

On reachability — I verified the behavior but could not demonstrate the input against either real provider, which is why this is a Suggestion and not a blocker. Two candidate paths, neither proven:

• backend/src/providers/compute/fly.provider.ts:551 — typeof a.timestamp === 'number' ? a.timestamp : Date.parse(…) takes a numeric timestamp without normalizing its unit, and the same file documents Fly's next_token as a nanosecond value (:564-566). A numeric-ns shape would make every line in a page ~1.7e18. Whether Fly's unofficial endpoint ever emits that, I can't say.
• A self-hosted backend host whose clock runs ahead, later NTP-corrected — that yields a bounded (skew-length) outage rather than a permanent one.

Fix I ran end-to-end — make the trust sticky rather than per-page, so a page can earn trust but never give it back. One line:

let clockTrusted = false;                                    // hoist out of positionableFor
const positionableFor = (lines: ComputeLogLine[]) => {
  const bound = Date.now() + CLOCK_SKEW_MS;
  clockTrusted = clockTrusted || lines.some((l) => Number.isFinite(l.timestamp) && l.timestamp <= bound);
  return (ts: number) => Number.isFinite(ts) && (!clockTrusted || ts <= bound);
};

Result: 25/25 of your tests stay green (including the slow-clock test, which never sees a plausible line and so never trusts the clock) and the probe above prints all four real-after-* lines. Worth a companion test whose page is uniformly future.

2. functionality — a slow client clock still duplicates output when the log window straddles the bound (src/commands/compute/logs.ts:189-193, :263-275)

The clockTrusted heuristic assumes a skewed clock makes the whole page look future. For a low-traffic service the window spans hours, so with a clock ≥5 min slow the older lines are still ≤ bound → clockTrusted is true → the recent lines get routed to the undated content-dedupe path. They print once when fresh, then print again later when they age past the sliding bound and re-enter the positionable path above lastTs.

Probe (reader clock 10 min behind, window = one old boot line + a growing set of distinct req-N lines, 200 polls):

printed=253  distinct=201  duplicated=51   e.g. req-0 ×2, req-1 ×2, req-2 ×2, req-3 ×2

This is pre-existing, not new — it fails at cd3bb32 and 2cb375d too, and 1b94f6f strictly improved the same scenario (there it was silent loss; here it is duplication). Duplication only, never loss, so it is well below the blocking bar — noting it because the fix that landed reads as a complete solution to clock skew and it isn't quite.

3. security — timestamp is the one printable field that bypasses the fetch-boundary sanitizer, and C1 bytes survive JSON.stringify (src/commands/compute/logs.ts:97-102, :69-77)

fetchComputeLogs deliberately passes timestamp through uncoerced (the comment at :91-96 explains why — an unusable timestamp must stay distinguishable). But formatLogLine:74 then prints String(line.timestamp) raw on the invalid-date path, and --json --follow emits JSON.stringify(line) — and JSON.stringify escapes C0 (�) but leaves C1 (0x80–0x9f) raw. Verified against the real boundary helper with { timestamp: "x�2J�]0;pwn" }:

boundary-kept : "x�2J�]0;pwn"        ← unsanitized
formatLogLine : "x�2J�]0;pwn  clean" ← C1 CSI 2J (erase display) reaches the terminal
NDJSON        : {"timestamp":"x�2J\\u001b]0;pwn"}  ← C1 raw, ESC escaped

This is defense-in-depth only — both providers construct timestamp as a number, so I could not reach it through a real backend; the exposure is the Cloud proxy path, which returns an unvalidated cast rather than parsing computeLogsResponseSchema. Still, the comment at :47-51 claims every printable field is covered in every output mode, and this is the exception. timestamp: typeof l.timestamp === 'number' ? l.timestamp : Number.NaN closes it while preserving the undated semantics the comment relies on (formatLogLine and maxTs already handle non-finite).

4. software engineering — a non-object entry inside lines[] throws out of the boundary helper (src/commands/compute/logs.ts:97-102; test at logs.test.ts "tolerates a malformed body")

The malformed-body test covers a null body, but not a null element. Verified:

fetchComputeLogs → TypeError: Cannot read properties of null (reading 'timestamp')

In --follow this lands in the poll catch, is classified non-transient by isTransientApiError (it isn't a CLIError), and rethrows — the tail dies on a raw TypeError. A .filter((l) => l && typeof l === 'object') before the .map, plus a lines: [null] case in that test, matches the defensiveness already applied to the body itself.

Information

• software engineering — Test coverage for the changed behavior is genuinely strong: 25/25 green locally (npx vitest run src/commands/compute/logs.test.ts, 547 ms), and the follow-loop tests are regression tests for real bugs found on this PR rather than happy-path filler. I negative-controlled the newest guard specifically (see adjudication above) and it is load-bearing. npx eslint clean on both touched files; npx tsc --noEmit reports zero errors under src/commands/compute/logs* (the repo has pre-existing errors elsewhere, unrelated to this PR).
• software engineering — Telemetry uses trackCommandUsage (logs.ts:126-133), which is correct: DEVELOPMENT.md:57-60 bans reportCliUsage for new commands as a legacy OSS path. The unawaited-in-follow-mode call is right, and the comment explains the observed stall it prevents. One consequence worth knowing: a --follow run that later errors emits a success event followed by a failure event, since the success call necessarily precedes the long-lived loop. Unique to this file's shape; acceptable as documented.
• security — Unicode bidi overrides survive the sanitizer: sanitizeLogMessage("user‮gnp.exe") returns the string unchanged, so container output can still reorder its rendered form (Trojan-Source style). Out of scope for a regex aimed at ANSI/OSC/C1, and cosmetic rather than executable — noting it only so the "attacker-adjacent data" comment at :44-51 isn't read as covering it.
• functionality — CONTROL_RUNS (:50) collapses newline runs at the fetch boundary, so a stack trace delivered as one entry loses its structure in --json too: "Error: boom\n at f()\n at g()" → "Error: boom at f() at g()". That is a terminal-rendering concern applied to machine-readable output — the very case the comment at :53-56 names. Sanitizing newlines at print time for the human path only would keep --json faithful for the agents the PR body targets.
• functionality — parseLimit(' ') returns 1, not 100: the guard at :63 special-cases '' but Number(' ') === 0, which then clamps up. Trivial and unlikely to be typed.
• performance — No performance concerns. Page size is clamped to 1–1000, --follow polls serially at a 2 s interval matching the server-side limiter, transient failures back off (capped at 30 s, 5 consecutive), and the per-poll allocations (new Map(lastTsCounts), undatedCounts) are O(page) with page ≤ 1000. lastTsCounts is cleared on watermark advance and prevUndated is replaced each poll, so nothing accumulates across a long tail. No DB access, no N+1, no blocking work on the event loop.

---

Verdict

approved — zero Critical findings. The blocking clock-skew bug from my previous round is fixed and correctly tested. The four Suggestions are all non-blocking: #1 is a verified permanent dead tail but I could not demonstrate its input against a real provider (and it has a one-line fix that keeps 25/25 green), #2 is pre-existing and duplication-only, #3 is defense-in-depth, #4 is robustness. Merging as-is is reasonable; #1 is the one I'd most like to see land, given this file's history of a fix over-correcting into its mirror.

(Informational only — the GitHub green check is a separate human action.)

Summary
Reviewed the new compute logs <id> command across software engineering, functionality, security, and performance; I found no blocking issues.

Requirements Context
I used the PR description, the added README docs at README.md:1094-1103, and the existing CLI development guidance. The intended behavior is: compute logs <id> fetches container stdout/stderr from GET /api/compute/services/:id/logs, clamps --limit to 1-1000, forwards --next-token as next_token, emits { lines, nextToken } under non-follow --json, and polls roughly every 2s under --follow. I also cross-checked the public backend route/schema, which expose lines[] and nullable nextToken: https://github.com/InsForge/InsForge/blob/main/backend/src/api/routes/compute/services.routes.ts#L648-L670 and https://github.com/InsForge/InsForge/blob/main/packages/shared-schemas/src/compute-services-api.schema.ts#L160-L175.

Verdict
Approved per the requested rule because there are zero Critical findings. Software engineering looks consistent with the repo’s command registration, output, auth, and telemetry patterns; functionality matches the stated API contract and README examples; security-relevant handling is appropriate for untrusted log text because printable fields are sanitized before all output modes; performance is bounded by the requested page limit and 2s follow polling, with no unbounded per-poll work beyond the capped page. I attempted npx vitest run src/commands/compute/logs.test.ts, but local execution failed before tests started because vitest/config was unavailable in this checkout without installed dependencies.

Summary

Re-review at e514b59a (sticky clock-trust). The sticky fix does what it says, but the clock-skew dead tail it descends from is still reachable — the guard added in cd3bb32/2cb375d only survives when every line in the window is future-dated, and one ordinary older line in the window defeats it.

Requirements context

This repo has no /docs/superpowers/; docs/specs/ holds only the diagnose and db-migrations designs, nothing matching this PR. The intent doc lives in another repo: InsForge/InsForge → .internal/docs/specs/2026-06-04-compute-container-logs-design.md. Its non-goals sanction this PR as the Phase-2 CLI surface, and it is directly load-bearing here:

Live tail in v1 = re-fetch the recent window on an interval (stateless; no cursor accumulation/dedup to get wrong).

The dashboard never sends next_token, so this CLI is the first consumer of the cursor path, and the spec pre-flagged the dedup as the thing to get wrong. It also documents that next_token is a nanosecond cursor while timestamp is normalized to epoch ms — the resolution mismatch the cursorAdvanced gate correctly handles.

Verification basis: npm ci in a pinned checkout of e514b59a; npx vitest run src/commands/compute/logs.test.ts → 26 passed; tsc --noEmit clean for src/commands/compute/*; eslint clean. Probes below were added as untracked test files and removed; the branch was never modified.

Findings

Critical

[functionality] A window containing any line older than CLOCK_SKEW_MS re-opens the clock-skew dead tail — src/commands/compute/logs.ts:194-199, 216-228, 259-268

positionableFor decides the local clock is trustworthy if some line in the page is within Date.now() + CLOCK_SKEW_MS. Old lines satisfy that predicate even when the clock is slow: with a clock 10 minutes behind the provider, bound = T − 5min, so any line older than 5 minutes is "plausible" and earns trust — permanently, now that trust is sticky. The bound is then applied to the new lines, all of which are > bound, routing the entire live tail into the content-only undatedCounts path at :220-228. That path keys on region|instance|message (:168) with no timestamp, so a repeated identical message is suppressed by occurrence count and never prints again.

A scrolling --limit 100 window on a service that has been up for a few minutes contains an older line essentially always, so the data half of the trigger is ordinary usage.

Probe — scrolling null-cursor window of [{ts: T−10min, "listening on :8080"}, {ts: T+n, "EADDRINUSE, retrying"}], 6 polls, server responses held fixed, only the client clock varied:

head	correct clock	clock 10 min slow
bd25fde	6/6 printed	6/6 printed
525a8b7	6/6	6/6
cd3bb32	6/6	6/6
2cb375d	6/6	1/6, then silent forever
1b94f6f	6/6	1/6
e514b59 (head)	6/6	1/6

Introduced by 2cb375d (routing non-positionable lines through the undated path) and untouched by both later fixes. cd3bb32 — which excluded such lines from maxTs but still printed them — was correct on both clocks; the follow-up traded a duplication bug (Suggestion severity) for a silent-loss one.

Why Critical rather than Suggestion: this is the same silent, self-sustaining dead tail on -f during a crash loop that was already accepted as blocking on this PR and fixed in 1b94f6f, and the test that claims it is fixed passes vacuously. logs.test.ts:263 ("--follow keeps tailing when the local clock is far behind the provider") uses a window of only recent lines, which is the one shape where the some(...) heuristic happens to hold. Adding a single old line to that same test's window turns it red. The PR states this condition as a requirement and ships a guard plus a test for it, so it is in scope by the author's own framing.

I proved the mechanism and the behavior; I did not measure how often a client clock is ≥5 min slow — that half is asserted, not demonstrated. It is an ordinary condition (sleep/resume, VMs and containers without NTP, CI runners) and the failure is silent, with the operator concluding "my app stopped logging".

Fix I ran end-to-end — key the undated dedupe on the timestamp as well. A non-positionable timestamp is still a stable identifier, even when it can't be ordered, so identical messages at different timestamps stay distinct while a genuinely re-sent line (same ts, same message) is still suppressed:

const lineKey = (l: ComputeLogLine) => `${l.region ?? ''}|${l.instance ?? ''}|${l.message}`;
// A timestamp that can't be ordered against the watermark is still a stable
// identifier for the line. Keying the undated dedupe on it keeps identical
// messages at DIFFERENT timestamps distinct, so a crash loop is never
// collapsed into a single printed line.
const undatedKey = (l: ComputeLogLine) => `${String(l.timestamp)}|${lineKey(l)}`;

then use undatedKey(l) in undatedCounts (:224) and in the !positionable(...) branch (:260). Result: all 26 existing tests stay green and both probes go green (28/28). I also tried tightening the trust predicate from some to "page max within bound"; that fixes this probe but reddens logs.test.ts:217, so it is not the right lever — the defect is in the dedupe key, not the heuristic.

Suggestion

[functionality] A bogus future timestamp on the first page still pins the watermark — logs.ts:194-205. clockTrusted starts false, so if no plausible line has been seen yet the bound is not applied, the future timestamp is positionable, and lastTs is pinned to it; every later real line is < lastTs and dropped. Probe: first page [{ts: now+1y}], then two real lines → 0 of 2 printed. logs.test.ts:284 only covers an all-future page after trust was earned. Stickiness narrowed this to the pre-trust window rather than closing it. Filed as Suggestion, not Critical, because I could not demonstrate either provider emitting a uniformly-future page — fly.provider.ts:551 taking a numeric timestamp without unit normalization remains the plausible-but-unproven path.

[software engineering] lines: [null] throws out of fetchComputeLogs — logs.ts:97-102. Array.isArray(body?.lines) guards the container but not the elements, so l.timestamp on a null element throws. Verified: TypeError: Cannot read properties of null (reading 'timestamp'). The existing "tolerates a malformed body" test pins a null body, not a null element. A .filter((l) => l && typeof l === 'object') before the .map closes it.

[security] timestamp is the one printable field that reaches the terminal unsanitized — logs.ts:98, :74, :143. The comment at :93-96 deliberately leaves timestamp uncoerced, which is right for the watermark semantics, but it also skips sanitization. A string timestamp carrying an 8-bit C1 CSI (0x9b) survives into both formatLogLine's String(line.timestamp) fallback and JSON.stringify(line) — verified: C1 present at offset 0 in both, while message is correctly stripped. JSON.stringify escapes C0 but leaves C1 raw, so --json is not a safe harbor. Defense-in-depth only (both providers emit numbers), and typeof l.timestamp === 'number' ? l.timestamp : NaN fixes it while preserving the undated semantics.

Information

[software engineering] parseLimit(' ') returns 1, not the default — logs.ts:62-67. Number(' ') === 0, which is finite, so it clamps up to 1 instead of falling back to DEFAULT_LIMIT. '' is special-cased at :63 but whitespace is not; raw.trim() === '' would cover both. A one-line window instead of 100 is surprising but not harmful.

[performance] No findings. Per-poll work is bounded by --limit (≤1000): two Map copies and a single pass over the page, no nested lookups or N+1. The 2s interval matches the server-side limiter the spec describes, transient failures back off (capped at 30s, 5 consecutive), and telemetry is deliberately not awaited in follow mode (:130-134) so the flush can't stall the tail.

Other dimensions checked, clean: encodeURIComponent on the service id and URLSearchParams for limit/next_token (no injection into the request path or query); requireAuth() before any fetch and no auth path weakened; no new dependencies; no secrets or PII logged. logs.ts correctly uses trackCommandUsage and does not call the legacy reportCliUsage — matching DEVELOPMENT.md:57-60, which bans it for new commands (the reportCliUsage still in events.ts is pre-existing). Registration in src/index.ts:82,280, README, and the integration test addition all follow existing compute-command conventions.

Stale review states: the five open CHANGES_REQUESTED reviews on this PR are all bound to superseded commits (7d29de0d, 6bbdf43a, 525a8b78, cd3bb329, 2cb375d6) and their findings are fixed at head — they should not be read as live blockers. The one Critical above is the only blocking item.

---

Verdict: request_changes — one Critical finding (clock-skew dead tail still reachable through an ordinary mixed-age window; verified fix above keeps all 26 existing tests green).

[jwfing]

Summary
The PR implements compute logs <id> with paging, JSON/NDJSON output, follow polling, docs, and focused tests; I found no blocking issues.

Requirements Context
I used the PR title/description, the README docs at README.md:1094-1102, the updated lifecycle-vs-container log comment at src/commands/compute/events.ts:9-12, and the repo development guide. The intended behavior is an authenticated GET /api/compute/services/:id/logs command with --limit, --next-token, --follow polling every ~2s, --json returning { lines, nextToken }, and --json --follow emitting NDJSON while compute events remains lifecycle events.

Findings

Critical

(none)

Suggestion

• src/commands/compute/logs.ts:73-76, src/commands/compute/logs.ts:97-102 — formatLogLine falls back to String(line.timestamp) for invalid timestamps, but fetchComputeLogs leaves timestamp unvalidated and unsanitized. If the backend ever returns a malformed string timestamp containing terminal control bytes, non-JSON output could print it raw despite the otherwise thorough log-field sanitization. Consider coercing timestamps to finite numbers or sanitizing the fallback string before formatting.

Information

• src/commands/compute/logs.test.ts:56-395 — Software engineering and functionality coverage is strong for URL construction, limit clamping, cursor forwarding, output shapes, follow dedupe/watermark edge cases, transient retry, and sanitization. I did not rerun the suite under the read-only review constraint.
• src/commands/compute/logs.ts:83-86, src/lib/api/oss.ts:234-284 — Security/auth posture follows existing compute conventions: service ids and cursors are URL encoded, requests go through authenticated ossFetch, and the PR adds no shell, SQL, or dependency surface.
• src/commands/compute/logs.ts:30-38, src/commands/compute/logs.ts:238-249 — Performance profile is bounded for the intended tailing workflow: each poll uses a fixed 2s interval with capped transient backoff, and per-page work is bounded by the 1-1000 limit.

Verdict
approved — no Critical findings; the timestamp sanitization note is non-blocking.

[jwfing]

Summary
The change is reviewable and matches the stated goal of exposing compute container stdout/stderr through compute logs.

Requirements Context
I used the PR description and README as the primary CLI contract: compute logs <id> [--limit 1-1000] [-f|--follow] [--next-token <t>] calls GET /api/compute/services/:id/logs, --json returns { lines, nextToken }, and --follow polls every 2s. I also checked the linked context: CLI PR #96 reserved compute logs for future real container logs, and backend/dashboard PR #1480 documents the logs endpoint, limit, next_token, auth/project checks, and 2s dashboard polling.

Findings

Critical
(none)

Suggestion

• src/commands/compute/logs.ts:121-122, src/commands/compute/logs.ts:238-250 — --follow retries transient failures only after the first successful fetch. If the initial request hits a shared-rate-limit 429, transient 5xx, or tagged network error, the command exits before entering the resilient poll loop. Consider applying the same transient retry path to the initial fetch when opts.follow is set, with a unit test for an initial 429 followed by success.

Information

• src/commands/compute/logs.ts:79-106, src/commands/compute/logs.ts:109-155, src/index.ts:270-280 — Software engineering/functionality: the command follows the repo’s registration, auth, ossFetch, root --json, and telemetry patterns; URL encoding, limit, next_token, human output, JSON output, and follow setup all line up with the documented intent.
• src/commands/compute/logs.test.ts:56-339, src/commands/compute/logs.test.ts:342-395, src/integration/compute.test.ts:100-110 — Test coverage is strong for the changed behavior: endpoint construction, limit clamping, cursor forwarding, formatting, JSON passthrough, sanitizer behavior, follow dedupe/cursor cases, transient poll retries, and an integration shape check.
• src/commands/compute/logs.ts:52-57, src/commands/compute/logs.ts:97-105, src/commands/compute/logs.ts:119-123 — Security: no SQL/shell execution or new dependencies; auth remains required, and untrusted log fields are sanitized before both human and JSON output. No security-relevant blocker found.
• src/commands/compute/logs.ts:62-66, src/commands/compute/logs.ts:238-250 — Performance: request size is bounded to 1-1000 lines, follow polling is sequential at the documented 2s cadence with capped transient backoff, and there is no N+1 or blocking I/O concern in the CLI path.

Verdict
Approved per the requested rubric: no Critical findings. The suggestion is non-blocking.

P2: In follow mode, the initial fetch now retries transient errors with exponential backoff (4s+8s+16s+30s ≈ 58s across 4 sleeps before the 5th consecutive failure throws), and no feedback is emitted until the first page succeeds. On the "ordinary" initial 429 the comment itself targets, `compute logs <id> --follow` prints nothing for up to a minute and looks hung — and in `--json --follow` there is no "Following logs..." message at all, so the user gets no signal that the tail is retrying.

Summary
No blocking issues found; this adds the intended compute logs <id> CLI surface with cursor paging, JSON/NDJSON output, follow polling, docs, and focused tests.

Requirements Context
I assessed the PR against the PR description, the added README command docs at README.md:1094-1103, the existing compute command conventions in src/commands/compute/*.ts, the CLI development guide in DEVELOPMENT.md, and the current InsForge Compute docs, which describe container logs as tail-able through dashboard, CLI, or MCP: https://docs.insforge.dev/core-concepts/compute/overview#logs.

Summary

Post-merge re-review of compute logs <id>: my previous round's Critical (the some(...) clock-trust heuristic vouched for by old lines, collapsing a slow-clock tail into content-only dedupe) is fixed and verified at the merged head — no Critical findings remain.

Note on timing: the PR merged while this review was running. fetch_pr reported head e784f826; I analysed that, then git ls-remote came back empty and the API showed state=closed / merged=true at 67ba77d3. I fetched and re-ran everything against 67ba77d3, so the findings below are against the merged code, not a stale head.

Verification: npx vitest run src/commands/compute/logs.test.ts → 28/28 green at 67ba77d3; eslint clean; tsc --noEmit clean for the PR's paths (repo-wide pre-existing errors filtered out). All findings below were reproduced with executable probes, not read off the source.

Requirements context

The CLI repo has no /docs/superpowers/ directory; docs/specs/ holds only the diagnose and db-migrations designs — nothing matching this PR. The intent doc lives in a different repo: InsForge/InsForge → .internal/docs/specs/2026-06-04-compute-container-logs-design.md. Its Non-goals say "No CLI in this PR — Phase 2 (compute logs <id> --follow)", which sanctions this PR as that Phase 2, and it documents the wire contract (data[].attributes { timestamp(RFC3339), message, instance, region } + meta.next_token, an ns-resolution cursor, ~7-day retention).

Worth recording, because it predicted this PR's whole review history: the spec chose "Live tail in v1 = re-fetch the recent window on an interval (stateless; no cursor accumulation/dedup to get wrong)". This PR deliberately takes on the cursor+dedupe the spec avoided, which is why the follow loop absorbed 16 heads of fixes. That's a reasonable call for a CLI (the dashboard can afford to re-render a window; a terminal tail cannot re-print one), but it is a scope expansion beyond the spec's v1 posture and it is where every remaining finding lives.

Conventions checked: trackCommandUsage, not the banned reportCliUsage (DEVELOPMENT.md:57-60) ✅; companion skills PR present per DEVELOPMENT.md §3 ✅; command registered in src/index.ts:277 alongside its siblings ✅.

Findings

Critical

(none)

Adjudicating my own prior blocker, with evidence — e1ca55c ("key the undated dedupe on timestamp too") closes it. Probe held the server responses fixed and varied only the client clock: 10-min-slow clock, window [{ts: T-10min, "listening"}, {ts: T+n, "EADDRINUSE"}], 6 polls.

head	EADDRINUSE printed
2cb375d / 1b94f6f / e514b59	1 / 6, then silent
e1ca55c … 67ba77d (merged)	6 / 6 ✅

The fix is in the right place: a timestamp that can't be ordered against the watermark is still a stable identifier, so undatedKey (logs.ts:195) keeps identical crash-loop messages at different timestamps distinct while still suppressing a genuinely re-sent line. I also confirmed the accompanying test fix is real — logs.test.ts:263 previously passed vacuously on an all-recent window (the one shape where some(...) accidentally holds); it now carries an old line like a real scrolling window does.

The five other open CHANGES_REQUESTED reviews are all bound to superseded commits (7d29de0d, 6bbdf43a, 525a8b78, cd3bb329, 2cb375d6) and every finding in them is fixed at 67ba77d3. Recording that here so the merged PR doesn't read as blocked.

Suggestion

Functionality — the Fly 0 timestamp sentinel is dropped forever, and the comment says otherwise. src/commands/compute/logs.ts:243-246 states that lines whose timestamp is unusable "(the Fly driver maps an unparseable one to 0/NaN)" are routed to the undated occurrence-count path. For NaN that holds; for 0 it does not — Number.isFinite(0) === true, so positionable(0) at logs.ts:225 returns true, and the line falls to l.timestamp < lastTs at logs.ts:284 and is skipped on every non-advancing poll. Probe: a window of [{ts:5000,"dated"}, {ts:0,"unparseable-ts-line"}] re-sent over 4 polls printed the unparseable line 0 times. Pre-existing (not introduced by the last three commits), and the load-bearing comment is what makes it worth fixing rather than re-deriving later. One clause closes it and keeps all 28 tests green:

return (ts: number) => Number.isFinite(ts) && ts > 0 && (!clockTrusted || ts <= bound);

Functionality — a first page in which every line is implausibly future still pins the watermark permanently. logs.ts:222-232: clockTrusted starts false, so on the very first page the bound is never applied, a bogus year-2100 timestamp is positionable, and lastTs is pinned to it. Every later real line is then < lastTs and silently dropped for the life of the tail. Probe: bogus first page followed by real-1/real-2 → 0 of 2 printed. Note logs.test.ts:289 ("survives a page in which every line is implausibly future") does not cover this — its bogus page is the second one, after trust is already earned. Reachability I could not demonstrate: I have no proof either provider emits a uniformly-future first page. The one named-but-unproven path is fly.provider.ts:551, which takes a numeric a.timestamp without normalizing its unit while :564 documents next_token as nanoseconds. Verified behaviour + unproven reachability ⇒ Suggestion, not Critical.

Functionality — one-time duplicate burst when the plausibility bound slides across the window. logs.ts:222-226 recomputes bound = Date.now() + CLOCK_SKEW_MS every poll while clockTrusted is sticky. On a clock ≥5 min slow, a tail can start with trust false (all lines positionable, watermark path), and later — as the bound slides forward in real time and crosses the older end of the window — trust flips to true, at which point the newest lines become non-positionable and re-enter through the undated path, where prevUndated has never seen them. They print a second time. Probe (static 2-line window spanning 60s, 200 polls / 400s):

head	10-min-slow clock	correct clock (control)
1b94f6f / e514b59 / e1ca55c / e784f82 / 67ba77d	line-b printed 2×	1× ✅

Pre-existing since 1b94f6f, not a regression from this round's commits — and it is duplication, never loss, one-time, bounded by --limit. Filing it so it is on record rather than as a merge blocker. Carrying prevUndated across the trust transition (or seeding it from lastTsCounts when clockTrusted first flips) would close it.

Software engineering — a null element in lines[] throws a raw TypeError. logs.ts:97-102 guards the container (Array.isArray(body?.lines)) but not the elements, so l.timestamp on a null entry throws. Probe: { lines: [null] } → TypeError: Cannot read properties of null (reading 'timestamp'). logs.test.ts:376 ("tolerates a malformed body") pins a malformed body, not a malformed element — worth reading that test against what it actually asserts. In --follow this kills the tail. A .filter((l) => l && typeof l === 'object') before the .map plus a test would cover it.

Information

• Security — timestamp is the one printable field left unsanitized. logs.ts:97-102 deliberately does not coerce it (documented, and correct for the follow semantics), but it reaches the terminal raw two ways: String(line.timestamp) in formatLogLine (logs.ts:74) and JSON.stringify(line) in print (logs.ts:163). I verified JSON.stringify escapes C0 but leaves C1 (0x80–0x9f) raw, so "JSON.stringify makes it safe" does not hold for the 8-bit CSI introducer the sanitizer at logs.ts:48 otherwise strips. Defense-in-depth only — both providers emit a number, and the backend type declares number — so this is a note, not a defect. typeof l.timestamp === 'number' ? l.timestamp : NaN would close it while preserving the undated semantics.
• The 67ba77d3 banner change is untested and slightly widened. Moving Following logs... (Ctrl+C to stop) ahead of the first fetch (logs.ts:189-191) is the right call — it fixes the ~58s silent wait an initial 429 could produce — but the !json guard was dropped in the move. Verified: --json --follow now emits the banner on stderr. Harmless for pipelines (stdout NDJSON stays clean) and arguably an improvement, but it is a deliberate behaviour change with no test pinning it either way. Also verified the banner now precedes a non-transient failure, so compute logs bad-id -f prints "Following logs..." and then "service not found" — cosmetic.
• MAX_CONSECUTIVE_POLL_FAILURES no longer means what its name says. After the e784f82 refactor the counter is local to a single fetchPage call (logs.ts:130), so it now bounds attempts within one fetch rather than consecutive failed polls. The behaviour is fine (5 attempts, ~58s of capped backoff, then fail; I confirmed exhaustion throws after exactly 5 calls), and collapsing the bespoke bookkeeping was a good simplification — the name and the comment at logs.ts:32-35 just now describe the old shape.
• parseLimit(' ') returns 1, not the default 100 (logs.ts:62-67): Number(' ') === 0 is finite, so it clamps up instead of falling back. '' is special-cased at :63 but whitespace is not. Trivial.
• Test quality is genuinely good, and I confirmed it rather than assuming it. Negative control on the two new retry tests: reverting the follow branch of fetchPage turns both --follow retries a transient failure on the INITIAL fetch and --follow retries transient poll failures and keeps tailing red. They pin real behaviour.
• Performance — nothing to flag. Per-fetch work is bounded by the 1–1000 --limit, polling is sequential at a fixed 2s matching the server-side limiter, backoff is capped at 30s, and the suppress/undatedSuppress/prevUndated maps are all bounded by page size and rebuilt per poll. No N+1, no unbounded accumulation, no blocking I/O on the loop. Not a DB-touching change, so no index considerations.
• Security — otherwise clean. No new dependencies; no SQL or shell; the service id is encodeURIComponent-ed into the path (logs.ts:86) and the cursor goes through URLSearchParams; auth is unchanged (requireAuth() + the existing ossFetch); no tokens, credentials, or PII are logged or added to telemetry (result_count and a boolean follow only). Sanitizing at the fetch boundary rather than at print is the right layer — it covers --json too.

Verdict

approved — zero Critical findings at the merged head 67ba77d3. The clock-trust Critical from the previous round is fixed and verified; everything remaining is a Suggestion or a note, and the two loss-shaped ones (the Fly 0 sentinel and the all-future first page) are pre-existing and worth a small follow-up rather than a revert. Since this landed while the review was in flight, the Suggestions above are offered as follow-up work.

(This is the bot's rubric verdict; the GitHub green checkmark remains a separate human action.)
