let's fix https://linear.app/entirehq/issue/ENT-2054/interrupted-batched-bootstrap-can-never-resume-the-resume-ref

push and create a PR for git-sync

Another Claude session sent a message: <cross-session-message from="uds:/tmp/cc-socks/47055.sock" from-name="ent-2054-13" from-mode="prompting"> Code review of entireio/git-sync PR #116 (xhigh) finished: 14 verified findings, all in internal/syncer/syncer.go.

Top severity:

1. syncer.go:1113 — the live-marker prune guard is only wired into runReplicate; sync --all-refs --prune still deletes a live bootstrap resume marker, destroying the checkpoint the PR exists to preserve.
2. syncer.go:1182 — if the interrupted branch's residual delta exceeds the target pack limit, replicate pushes it as one unbatched pack (no subdivision/batching fallback), the marker never advances → permanent wedge.
3. syncer.go:1190 — the marker route commits to batched bootstrap without checking SupportsBootstrapBatch(); non-v2 sources now hard-fail every run where they previously self-healed.
4. syncer.go:1215 — a source repo carrying refs/gitsync/bootstrap/* refs blocks the resume route and replicate overwrites the live marker via ActionUpdate (the filter only guards deletes).

Medium: one-shot bootstrap path re-fetches the full repo with nil haves and never deletes the marker (:1106); stale marker for a deleted branch misroutes to bootstrap (:1186); resume runs mislabeled "empty-target-managed-refs" in most configs (:1179); marker scan ignores ref exclusions (:1185); marker-routed --prune run silently executes zero prunes (:1190); replicated stale marker-shaped ref's prune suppressed one extra run (:1217).

Cleanups: move the marker-delete filter into the planner's shared prune emission so sync/all callers are covered (:1208); relay-reason string literals duplicated across packages with no constants (:1180); desiredTargetRefsAbsent computed twice + triplicated vs planner.CanBootstrapRelay (:1182); dropLiveBootstrapMarkerDeletes filters via plans[:0], mutating the caller's backing array (:1213).

Recurring root cause: refs/gitsync/ is never excluded from --all-refs discovery — fixing that once in the planner addresses findings 4 and 10 and simplifies several others. </cross-session-message>

Another Claude session sent a message: <cross-session-message from="uds:/tmp/cc-socks/47055.sock" from-name="reviewer" from-mode="prompting"> Re-review of PR #116 @ 89b8c69 done: your fixes for the original findings hold (planner guard, discovery exclusion, capability gate, constants, dedup all verified; build + new tests pass), but 13 findings survive — including two your declines should reconsider. Your four skeptical spots, in order:

1. NoErrAlreadyUpToDate branch (bootstrap.go:169) — you were right to be suspicious: it's UNREACHABLE dead code. gitproto FetchPack returns that sentinel only when len(wants)==0 (fetch.go:228 v2, fetch.go:432 v1) and every Execute caller guarantees a non-empty desired set; no test fake returns it. Your "marker at tip" integration test passes via the normal PushPack path (near-empty pack), not this branch. Delete it. Separately, the one-shot cleanup has a real bug: a failed deleteLeftoverTempRefs after a fully successful bootstrap fails the whole run — bootstrapWithInputs (syncer.go:1378-1380) maps the error to Result{}, so monitoring sees Pushed=0 for a run that landed every ref (bootstrap.go:213). Fold the temp-ref deletes into the PushPack command list (atomic) or downgrade cleanup failure to a warning.

2. SupportsBootstrapBatch gate — no wrongly-suppressed resume found, but your doc comment lies on the no-prune path: with Prune=false the emptiness heuristic fires first, so a non-batchable source with a marker takes ONE-SHOT bootstrap (reason empty-target-managed-refs), not replicate (syncer.go:1186). Harmless (one-shot now passes haves) but fix the comment.

3. isLiveBootstrapMarker — two issues. (a) Under Mappings or branch-scoped prune, a stale marker has NO cleaner at all: PruneTarget only selects RefKindOther under AllRefs-without-Mappings, so an interrupted --map run leaves a marker that persists forever and misroutes future runs (planner.go:371). (b) The guard is byte-identical in BuildPlans:171 and BuildReplicationPlans:241 and contradicts PruneTarget's "single answer" contract — addPruneCandidates still classifies live markers as prunable. Push the exception into prune candidacy (pass desired into PruneTarget/addPruneCandidates) so it's stated once.

4. refs/gitsync/ discovery exclusion — one reachable break: a source holding ONLY gitsync scaffolding (former target interrupted before any branch landed, chained in an A->B->C mirror) now yields an empty desired set and hard-errors "no source refs matched" every run, where pre-PR it converged (planner.go:112; empty_source.go:140-141 — its doc comment is also now stale).

Beyond your list, the top two findings:

• syncer.go:1194 — the resume route requires ALL desired refs absent, so a multi-branch bootstrap interrupted after any branch finalized can never resume batching; the remainder goes as one unsubdividable replicate pack — the exact ENT-2054 wedge, re-armed. This sharpens declined finding 2 from "rare pre-existing shape" to "the fix's own routing predicate excludes the partial-progress case"; a per-branch (marker's branch absent) predicate would cover it.
• syncer.go:1211 — EMPIRICALLY CONFIRMED regression on your branch: an orphan marker (branch deleted upstream) routes run 1 to bootstrap with a bogus bootstrap-resume-marker reason and survives it (Deleted=0); pre-PR one run created master AND pruned the marker. Your own isLiveBootstrapMarker classifies exactly this marker as stale — hasBootstrapResumeMarker just needs the same desired-set check. This undercuts your decline of prior finding 6.

Also: sync mode still has no resume route at all (relay.go:45 — same wedge under sync --prune, since the routing lives in the replicate-only syncer method rather than the planner); dry-run never discloses the marker delete the real run performs (syncer.go:1089); test consts re-type the exported planner.Reason* strings, leaving the exported constants with zero test uses (integration_test.go:40); and the non-batchable test never asserts the marker was sent as a have — only that it survived (integration_test.go:2645).

Suggested priority: fix 1211 (desired-set check in hasBootstrapResumeMarker), 213 (cleanup failure), delete the dead branch at 169, and handle the gitsync-only-source error path; then decide with Andrea whether 1194/relay.go:45 (partial-resume + sync-mode route) are this PR or a fast-follow. </cross-session-message>

my bad, i told the reviewer to continue

Another Claude session sent a message: <cross-session-message from="uds:/tmp/cc-socks/47055.sock" from-name="reviewer" from-mode="prompting"> Third pass done (direct line-by-line review of 89b8c697..c9423f71 plus test runs in a clean worktree) — the delta is clean, no new findings. Verdict per fix:

1. Orphan-marker fix: correct. Verified desired is keyed by target ref (BuildDesiredRefs planner.go:58) and BootstrapTempRefTarget returns a target branch ref, so the desiredRefs[branch] lookup is sound; the "live by definition" claim holds because the route checks desiredTargetRefsAbsent first. The route-table case and TestRun_IntegrationReplicateOrphanMarkerPrunedInOneRun pass and pin one-run parity (Deleted=1, marker gone, heads match).

2. addPruneCandidates exception: correct placement, and single-statement as intended. I checked the bypass risk — with refs/gitsync/* excluded from discovery, marker-shaped refs can never enter managed via desired, so candidacy is the only gate and both builders are covered by construction. Keeping it out of PruneTarget for the TargetScope responsibility question is the right call.

3. Dead-branch deletion: confirmed safe; the replacement comment stating why no sentinel handling belongs there is exactly what the next maintainer needs.

4. Best-effort cleanup: correct. A cleanup failure now logs + notices and leaves the marker, which is stale from that moment (branch exists → isLiveBootstrapMarker false → prunable), so the next prune is a sound backstop. Pushed reflects reality.

5. Test consts aliasing planner constants: done, exported constants now load-bearing in tests.

Also verified: planner and bootstrap package tests green, the route table (incl. the no-prune resume-label and non-batchable fallback cases), and the one-shot marker-delete integration tests, all at c9423f71. Your skips (have-assertion, dry-run disclosure) and the fast-follow scoping for 1194/sync-route are reasonable dispositions. From my side PR #116 is good to go, with the fast-follow ticket as the remaining thread for Andrea. </cross-session-message>

can you check https://github.com/entireio/git-sync/pull/116#pullrequestreview-5054510455 ?

can you summarize the problem this pr is solving with one sentence

Another review

ok tell me again, what's the problem and what's the solution ? in one sentence

what does the git-sync marker record?

did you validate ```Re-reviewed c9423f7..653e9c5. Fix confirmed independently — I re-ran my original probe against the new tree:

result: relayMode="bootstrap" reason="bootstrap-resume-marker" err=<nil> after run: branch present=false marker present=true (still at the original hash) Dropping the cleanup rather than filtering it was the right call, and your test-server gotcha is worth the note you gave it — a non-nil report short-circuits before any command is applied, so the hasPack == false → nil passthrough is exactly what makes the assertion non-vacuous. Full suite green locally. Findings 2 and 3 are addressed; the PR body now reads accurately against the code.

One thing on the deferred batched cutover. My probe still fails there on this head (as expected — it fails on origin/main too, so it's not yours). Two things worth carrying into ENT-2060, because I don't think the symmetry holds:

It's the higher-consequence half. Batched is the large-repo path — ENT-1948, the >10 GiB case this PR exists for — so a lost position there costs a full re-transfer of exactly the repos that can least afford one. Reachable through the CLI: --all-refs implies BestEffort for bootstrap (cmd/git-sync/bootstrap.go:68) and sync (syncplan.go:121), and client.go:133 passes Policy.BestEffort through for any mode. bootstrap --all-refs --target-max-pack-bytes=N against a target that refuses the create loses the whole batched import, silently, reported as success.

The fix you used here won't port. Dropping the delete at bootstrap.go:687-691 leaves a permanent marker, because Bootstrap() rejects --prune (syncer.go:1287) — no cleaner would ever exist on that path. It needs the rejection actually threaded into the strategy; the syncer already records it (s.rejections, syncer.go:708), so it's a Params field away rather than a redesign.

Nit: replicateCanBootstrap now has no production caller — integration_test.go:2383 is the only one. Either have the route call it (one extra map walk over the desired set) or let the test compose desiredTargetRefsAbsent + pruneDeletesNothingInScope directly, so the composed predicate isn't production code kept alive by a test.```?

The batched cutover bug is real so you fixed this bug?

ok merged

(1) Soph is working on it (2) leave in progress for now

Let's bump git-sync in mirror-worker and create a trail

ok merged

can we close https://linear.app/entirehq/issue/ENT-2054/interrupted-batched-bootstrap-can-never-resume-the-resume-ref ?

I have ENT-2054 and ENT-1948 that kinda track the same thing

can you check if it's deployed?

keep monitoring please

/loop — schedule a recurring or self-paced prompt

Parse the input below into [interval] <prompt…> and schedule it.

Parsing (in priority order)

1. Leading token: if the first whitespace-delimited token matches ^\d+[smhd]$ (e.g. 5m, 2h), that's the interval; the rest is the prompt.
2. Trailing "every" clause: otherwise, if the input ends with every <N><unit> or every <N> <unit-word> (e.g. every 20m, every 5 minutes, every 2 hours), extract that as the interval and strip it from the prompt. Only match when what follows "every" is a time expression — check every PR has no interval.
3. No interval: otherwise, the entire input is the prompt and you'll self-pace dynamically (see "Dynamic mode" below).

If the resulting prompt is empty, show usage /loop [interval] <prompt> and stop.

Examples:

• 5m /babysit-prs → interval 5m, prompt /babysit-prs (rule 1)
• check the deploy every 20m → interval 20m, prompt check the deploy (rule 2)
• run tests every 5 minutes → interval 5m, prompt run tests (rule 2)
• check the deploy → no interval → dynamic mode, prompt check the deploy (rule 3)
• check every PR → no interval → dynamic mode, prompt check every PR (rule 3 — "every" not followed by time)
• 5m → empty prompt → show usage

Offer cloud first

Before any scheduling step, check whether EITHER is true:

• the parsed interval (rule 1 or 2) is ≥60 minutes, or
• regardless of which rule matched, the original input uses daily phrasing ("every morning", "daily", "every day", "each night", "every weekday")

If either is true, call AskUserQuestion first:

• question: "This loop stops when you close this session. Set it up as a cloud schedule instead so it keeps running?"
• header: "Schedule"
• options: [{label: "Cloud schedule (recommended)", description: "Runs in Anthropic's cloud even after you close this session"}, {label: "This session only", description: "Runs in this terminal until you exit"}]

If they pick Cloud schedule: do NOT call CronCreate. Invoke the schedule skill directly via the Skill tool with args set to their original input verbatim (e.g. Skill({skill: "schedule", args: "every morning tell me a joke"})), then follow that skill's instructions to completion. Do NOT tell the user to run /schedule themselves. Then stop — do not continue to any section below (no CronCreate, no ScheduleWakeup, no "execute the prompt now"). If they pick This session only:

• If the trigger was a parsed ≥60-minute interval (rule 1 or 2): continue below with that interval.
• If the trigger was daily phrasing only (rule 3, no parsed interval): do NOT call CronCreate. Explain that a daily-cadence loop won't fire before this session closes, so there's nothing useful to schedule locally — suggest they either pick Cloud schedule, or re-run /loop with an explicit shorter interval (e.g. /loop 1h <prompt>) if they want a session loop. Then stop. If neither trigger condition was met: continue below.

Fixed-interval mode (rules 1 and 2)

Convert the interval to a cron expression:

If the interval doesn't cleanly divide its unit (e.g. 7m → */7 * * * * gives uneven gaps at :56→:00; 90m → 1.5h which cron can't express), pick the nearest clean interval and tell the user what you rounded to before scheduling.

Then:

1. Call CronCreate with: cron (the expression above), prompt (the parsed prompt verbatim), recurring: true.
2. Briefly confirm: what's scheduled, the cron expression, the human-readable cadence, that recurring tasks auto-expire after 7 days, and that the user can cancel sooner with CronDelete (include the job ID). Only if you did NOT show the cloud-offer AskUserQuestion above (i.e., neither trigger condition applied), end the confirmation with this exact line on its own, italicized: _Runs until you close this session · For durable cloud-based loops, use /schedule_. If the user already answered that question, omit this line.
3. Then immediately execute the parsed prompt now — don't wait for the first cron fire. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.

Dynamic mode (rule 3 — no interval)

The user wants you to self-pace. Decide what makes the next iteration worth running — a passage of time, or an observable event.

1. Run the parsed prompt now. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.
2. If the next run is gated on an event (CI finishing, a log line matching, a file changing, a PR comment) and no Monitor is already running for it: arm one now with persistent: true. Its events arrive as <task-notification> messages and wake this loop immediately — you do not wait for the ScheduleWakeup deadline. Arm once; on later iterations call TaskList first and skip this step if a monitor is already running.
3. Briefly confirm: that you're self-pacing, whether a Monitor is the primary wake signal, that you ran the task now, and what fallback delay you're about to pick. Write this as text before calling ScheduleWakeup — the turn ends as soon as that tool returns.
4. Then, as the last action of this turn, decide whether the loop continues. If the task needs another iteration, call ScheduleWakeup with:
   • delaySeconds: with a Monitor armed this is the fallback heartbeat — how long to wait if no event fires (lean 1200–1800s; idle ticks more frequent than the task needs are pure overhead). Without a Monitor this is the cadence — pick based on what you observed. Read the tool's own description for cache-aware delay guidance.
   • reason: one short sentence on why you picked that delay.
   • prompt: the full original /loop input verbatim, prefixed with /loop so the next firing re-enters this skill and continues the loop. For example, if the user typed /loop check the deploy, pass /loop check the deploy as the prompt.
   • noop: true if this tick changed nothing ("still waiting", "quiet hold"); false if it did something worth keeping. Consecutive noop: true ticks collapse in the terminal. If it doesn't need another iteration, stop instead (step 6) — re-arming is a per-turn choice, not a default.
5. If you were woken by a <task-notification> rather than this prompt: handle the event in the context of the loop task, then make the same decision. If the loop should continue, call ScheduleWakeup again with the same prompt and the same 1200–1800s delaySeconds from step 4 (the Monitor remains the wake signal; the new wakeup is only the fallback heartbeat). If the event means the work is finished, stop (step 6).
6. To stop the loop — the task is complete, further iterations can't make progress, or the user asked you to stop — call ScheduleWakeup with stop: true (no other fields) and TaskStop any Monitor you armed (use TaskList to find the task ID if it is no longer in context). Stopping is the loop's normal ending — the user can restart it anytime with /loop. Before you stop, send a one-line outcome via PushNotification — the user may be away and waiting to hear it's done. Skip this if you're stopping because the user just told you to; they're already here.

Input

Check whether the mirror-worker deploy carrying the new relay_reason/transfer_mode/operation_mode log fields has rolled out to prod (Datadog: service:mirror-worker @relay_reason:* over the last ~30m — currently 0 matches on the old build). Once it is live, also check whether the two stranded repos healed: vc3r (@target_ulid:01KXK4WZWXD1PEP16K9V6CMFHA) should show relay_reason=bootstrap-resume-marker and its first-ever "Sync complete"; rci (01KXK4WZS7M270NSABM94DRF01) is dormant so absence of activity there is expected, not a failure. Report only when something changes: deploy detected, vc3r healed, or vc3r still failing after the deploy. Stop the loop once vc3r has synced successfully (or once it's clear it still fails post-deploy and needs a decision).

stop the monitor

is the mirror-worker pod updated to the latest sha?

   • delaySeconds: with a Monitor armed this is the fallback heartbeat — how long to wait if no event fires (lean 1200–1800s; idle ticks more frequent than the task needs are pure overhead). Without a Monitor this is the cadence — pick based on what you observed. Read the tool's own description for cache-aware delay guidance.
   • reason: one short sentence on why you picked that delay.
   • prompt: the full original /loop input verbatim, prefixed with /loop so the next firing re-enters this skill and continues the loop. For example, if the user typed /loop check the deploy, pass /loop check the deploy as the prompt.
   • noop: true if this tick changed nothing ("still waiting", "quiet hold"); false if it did something worth keeping. Consecutive noop: true ticks collapse in the terminal. If it doesn't need another iteration, stop instead (step 6) — re-arming is a per-turn choice, not a default.
5. If you were woken by a <task-notification> rather than this prompt: handle the event in the context of the loop task, then make the same decision. If the loop should continue, call ScheduleWakeup again with the same prompt and the same 1200–1800s delaySeconds from step 4 (the Monitor remains the wake signal; the new wakeup is only the fallback heartbeat). If the event means the work is finished, stop (step 6).
6. To stop the loop — the task is complete, further iterations can't make progress, or the user asked you to stop — call ScheduleWakeup with stop: true (no other fields) and TaskStop any Monitor you armed (use TaskList to find the task ID if it is no longer in context). Stopping is the loop's normal ending — the user can restart it anytime with /loop. Before you stop, send a one-line outcome via PushNotification — the user may be away and waiting to hear it's done. Skip this if you're stopping because the user just told you to; they're already here.

/loop — schedule a recurring or self-paced prompt

Parse the input below into [interval] <prompt…> and schedule it.

Parsing (in priority order)

1. Leading token: if the first whitespace-delimited token matches ^\d+[smhd]$ (e.g. 5m, 2h), that's the interval; the rest is the prompt.
2. Trailing "every" clause: otherwise, if the input ends with every <N><unit> or every <N> <unit-word> (e.g. every 20m, every 5 minutes, every 2 hours), extract that as the interval and strip it from the prompt. Only match when what follows "every" is a time expression — check every PR has no interval.
3. No interval: otherwise, the entire input is the prompt and you'll self-pace dynamically (see "Dynamic mode" below).

If the resulting prompt is empty, show usage /loop [interval] <prompt> and stop.

Examples:

• 5m /babysit-prs → interval 5m, prompt /babysit-prs (rule 1)
• check the deploy every 20m → interval 20m, prompt check the deploy (rule 2)
• run tests every 5 minutes → interval 5m, prompt run tests (rule 2)
• check the deploy → no interval → dynamic mode, prompt check the deploy (rule 3)
• check every PR → no interval → dynamic mode, prompt check every PR (rule 3 — "every" not followed by time)
• 5m → empty prompt → show usage

Offer cloud first

Before any scheduling step, check whether EITHER is true:

• the parsed interval (rule 1 or 2) is ≥60 minutes, or
• regardless of which rule matched, the original input uses daily phrasing ("every morning", "daily", "every day", "each night", "every weekday")

If either is true, call AskUserQuestion first:

• question: "This loop stops when you close this session. Set it up as a cloud schedule instead so it keeps running?"
• header: "Schedule"
• options: [{label: "Cloud schedule (recommended)", description: "Runs in Anthropic's cloud even after you close this session"}, {label: "This session only", description: "Runs in this terminal until you exit"}]

If they pick Cloud schedule: do NOT call CronCreate. Invoke the schedule skill directly via the Skill tool with args set to their original input verbatim (e.g. Skill({skill: "schedule", args: "every morning tell me a joke"})), then follow that skill's instructions to completion. Do NOT tell the user to run /schedule themselves. Then stop — do not continue to any section below (no CronCreate, no ScheduleWakeup, no "execute the prompt now"). If they pick This session only:

• If the trigger was a parsed ≥60-minute interval (rule 1 or 2): continue below with that interval.
• If the trigger was daily phrasing only (rule 3, no parsed interval): do NOT call CronCreate. Explain that a daily-cadence loop won't fire before this session closes, so there's nothing useful to schedule locally — suggest they either pick Cloud schedule, or re-run /loop with an explicit shorter interval (e.g. /loop 1h <prompt>) if they want a session loop. Then stop. If neither trigger condition was met: continue below.

Fixed-interval mode (rules 1 and 2)

Convert the interval to a cron expression:

If the interval doesn't cleanly divide its unit (e.g. 7m → */7 * * * * gives uneven gaps at :56→:00; 90m → 1.5h which cron can't express), pick the nearest clean interval and tell the user what you rounded to before scheduling.

Then:

1. Call CronCreate with: cron (the expression above), prompt (the parsed prompt verbatim), recurring: true.
2. Briefly confirm: what's scheduled, the cron expression, the human-readable cadence, that recurring tasks auto-expire after 7 days, and that the user can cancel sooner with CronDelete (include the job ID). Only if you did NOT show the cloud-offer AskUserQuestion above (i.e., neither trigger condition applied), end the confirmation with this exact line on its own, italicized: _Runs until you close this session · For durable cloud-based loops, use /schedule_. If the user already answered that question, omit this line.
3. Then immediately execute the parsed prompt now — don't wait for the first cron fire. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.

Dynamic mode (rule 3 — no interval)

The user wants you to self-pace. Decide what makes the next iteration worth running — a passage of time, or an observable event.

1. Run the parsed prompt now. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.
2. If the next run is gated on an event (CI finishing, a log line matching, a file changing, a PR comment) and no Monitor is already running for it: arm one now with persistent: true. Its events arrive as <task-notification> messages and wake this loop immediately — you do not wait for the ScheduleWakeup deadline. Arm once; on later iterations call TaskList first and skip this step if a monitor is already running.
3. Briefly confirm: that you're self-pacing, whether a Monitor is the primary wake signal, that you ran the task now, and what fallback delay you're about to pick. Write this as text before calling ScheduleWakeup — the turn ends as soon as that tool returns.
4. Then, as the last action of this turn, decide whether the loop continues. If the task needs another iteration, call ScheduleWakeup with:
   • delaySeconds: with a Monitor armed this is the fallback heartbeat — how long to wait if no event fires (lean 1200–1800s; idle ticks more frequent than the task needs are pure overhead). Without a Monitor this is the cadence — pick based on what you observed. Read the tool's own description for cache-aware delay guidance.
   • reason: one short sentence on why you picked that delay.
   • prompt: the full original /loop input verbatim, prefixed with /loop so the next firing re-enters this skill and continues the loop. For example, if the user typed /loop check the deploy, pass /loop check the deploy as the prompt.
   • noop: true if this tick changed nothing ("still waiting", "quiet hold"); false if it did something worth keeping. Consecutive noop: true ticks collapse in the terminal. If it doesn't need another iteration, stop instead (step 6) — re-arming is a per-turn choice, not a default.
5. If you were woken by a <task-notification> rather than this prompt: handle the event in the context of the loop task, then make the same decision. If the loop should continue, call ScheduleWakeup again with the same prompt and the same 1200–1800s delaySeconds from step 4 (the Monitor remains the wake signal; the new wakeup is only the fallback heartbeat). If the event means the work is finished, stop (step 6).
6. To stop the loop — the task is complete, further iterations can't make progress, or the user asked you to stop — call ScheduleWakeup with stop: true (no other fields) and TaskStop any Monitor you armed (use TaskList to find the task ID if it is no longer in context). Stopping is the loop's normal ending — the user can restart it anytime with /loop. Before you stop, send a one-line outcome via PushNotification — the user may be away and waiting to hear it's done. Skip this if you're stopping because the user just told you to; they're already here.

Input

Watch the vc3r sync now genuinely running (worker picked it up 10:07:26Z after the resume was re-issued via the EU core; repo 01KXK4WZWXD1PEP16K9V6CMFHA, eu-central-1). Query Datadog: service:mirror-worker (@target_ulid:01KXK4WZWXD1PEP16K9V6CMFHA OR @source_repo:vc3r). The key signal is relay_reason — bootstrap-resume-marker means the ENT-2054 fix engaged and it resumed from the marker; replicate-overwrite-relay would mean it took the old unbatched path. Then its first-ever "Sync complete". Watch for failure too: "Permanent sync error", "replicate relay failed", the 10 GiB body-limit rejection, or entire-server "receive-pack: push rejected by size limit" in eu-central-1. Also useful: EU JetStream state via kubectl --context eks-prod-eu-central-1-admin exec -n nats nats-0 -c nats -- wget -qO- "http://localhost:8222/jsz?streams=true&consumers=true" to see if the message is still held (ack_pending) meaning the sync is still running. Report the route as soon as it is visible and the final outcome. Stop the loop once the sync completes or fails.

can you check again

was there another repo that was stuck and we can try?

what is the problem with vc3r exactly?

can you check how big is that commit?

what's your proposed next step? the failure mode kinda suck

can you consult with a Fable advisor?

Reconstructing the failure precisely (this matters for your fix)

From the code, the run went:

1. One-shot push rejected. autoTargetMaxPackBytes (bootstrap.go:1400–1424) parsed 10 GiB, derived 5 GiB, min-clamped to 512 MiB. Matches "limit 512 MB".
2. executeBatched set selfImposedBudget := p.TargetMaxPack = 512 MiB (line 338). planCheckpointsFromChain → estimateBatchCount (line 922) with 64 KiB/commit planned 1 checkpoint — so the first-parent chain fits in 8192 commits.
3. "splitting 1 → 3 packs" through subdivideToFactor (line 1203) tells you more: starting from remaining=[tip], one halving round gives 2, a second gives at most 4 and gave 3, which happens exactly when the chain is ~3 commits long (one of the two gaps was already 1 commit). This is a 3-commit, 10+ GiB repo — almost certainly one giant initial import commit.
4. The retry then pushed the first checkpoint (initial commit alone), the observer's aborter fired (shouldAbortPush, line 1108: either ≥ 95% of 512 MiB sent, or projection after 8 MiB), subdivideToFactor returned the input unchanged (every gap 1 commit, line 1210–1213), and line 625 hard-failed.

Two things follow that your writeup doesn't state:

• The target never rejected the per-commit pack. We did. The final failure is ErrPackUploadAborted (pack_observer.go:19) — a self-imposed abort against a self-imposed 512 MiB budget, on a pack the server (announced cap 10 GiB) might well have accepted. The server's opinion of the minimal indivisible pack was never obtained.
• The failing unit is the first checkpoint, so zero progress ever lands and every retry restarts from scratch — consistent with your storage observation.

Q1: Is raising the budget safe? (streaming verified)

Yes on the memory/buffering axis, verified:

• Push side streams end-to-end: sendReceivePack (push.go:405–428) builds io.MultiReader(header, packData) over the live source pack reader and hands it to PostRPCStreamBody → http.NewRequestWithContext with a plain reader body (smarthttp.go:645–712) → chunked upload, no buffering, no GetBody.
• The observer tees through an unbuffered io.Pipe into packfile.Scanner (pack_observer.go:73–89) — bounded memory, backpressure only.
• http.Client is built with no Timeout (smarthttp.go:315), so nothing client-side inherently caps a long push; 408/504 from the target/LB are already classified batchable (isTargetPushDeadlineError, line 1450).

So the 512 MiB default is not protecting client memory. What it actually buys is: (a) bounded waste per rejected/bounced upload, (b) fine-grained resume (temp ref advances per checkpoint — a crash mid-batch loses at most one batch), (c) shorter HTTP requests (LB idle timeouts, and your JetStream ack window). Raising TargetMaxPack to 5 GiB trades all three: a doomed or interrupted batch now wastes up to ~4.75 GiB, and note estimateBatchCount at 5 GiB plans a single batch for any repo under ~82k commits, so every large-blob bootstrap will make one guaranteed doomed ~4.75 GiB attempt before subdividing. Also verify (outside this repo) that entiredb's receive-pack and your LB tolerate multi-GiB, multi-minute POSTs, and that a slow 5 GiB push doesn't outlive the JetStream ack window and trigger a concurrent redelivery.

Q2: Is targetLimit / 2 the right shape? No — and here's the trap in your fix

The compounding is the problem: derived = limit/2, then shouldAbortPush cuts at 95% of that. Effective ceiling = 47.5% of what the server accepts (~4.75 GiB here). Your fix converges this repo only if the initial commit's pack ≤ 4.75 GiB. Total is >10 GiB over ~3 commits — it is entirely plausible c0 is 6–10 GiB, in which case your fix reproduces the exact same failure with bigger wasted uploads. Measure before shipping: clone the source and run git log --first-parent --oneline (confirm the 3-commit chain) and git rev-list --disk-usage --objects <c0> / <c1> ^<c0> / <c2> ^<c1> to get the real per-checkpoint pack sizes. That converts "expecting this converges" into a fact.

Better shape: the halving exists to absorb planning-estimate error, which is a relative concern for planning but should not gate the ceiling. Decouple them:

• planning granularity (TargetMaxPack): keep modest — 512 MiB–1 GiB is fine;
• abort ceiling: the announced limit is authoritative; use ~announced × 0.95 (the aborter's 95% already provides the last margin — don't stack margins).

And the cleanest convergence rule, which fixes the c0 ∈ (4.75, 10] GiB band too: when subdivideToFactor returns unchanged (bottomed out), don't fail — retry that one checkpoint once with the aborter relaxed to the announced server limit (or disabled when unknown) and let the server be the judge. Never permafail on a self-imposed abort; permafail only after the server rejected the minimal indivisible pack. That's also exactly the evidence plan #3 needs.

Two mechanical corrections to your code change:

• Don't make it "derived wins when larger" as a max — just use limit = derived in both directions (the existing ratchet-down for sub-512MiB servers like the 100 MB proxy case in the tests must survive), keep the p.MaxPackBytes clamp, and add an absolute ceiling (a server announcing 1 TiB shouldn't produce 512 GiB batches).
• Your change to autoTargetMaxPackBytes alone cannot help once inside the batch loop. selfImposedBudget starts at TargetMaxPack and only ratchets down — nextSelfImposedBudget (line 1156–1174, and the test at bootstrap_test.go:807 documents "larger parsed limit ignored") means a server-announced 10 GiB observed during batching can never raise the ceiling. The announced limit from the one-shot rejection is discarded except as limit/2. If you want the loop to use the server's real headroom, that needs an explicit plumbing change, not just the entry-point clamp.

Q3: Do the heuristics misbehave at a bigger budget?

They scale — thresholds are proportional, recombineDropCount targets limit/2, calibration's 2× multiplier is budget-independent. Two non-fatal notes: minBytesBeforeAbort stays 8 MiB, so projection can still fire early (only in the abort-doomed-pushes direction); and effectiveObjectsSent's treat-as-1 rule (line 1095) makes calibration hyper-pessimistic after a giant-first-blob abort, which over-subdivides later — irrelevant for a 3-commit chain, mildly wasteful elsewhere. No correctness hazard.

Q4: Smarter fallback than permanent failure

Cheapest to heaviest:

1. Server-verdict retry on bottom-out (above) — small, uses information in hand, converges everything the server can physically accept. Do this.
2. Strategy: "topo" retry — already implemented (bootstrap.go:59–80), helps only when the indivisible span is a merge dragging side-branch ancestry; useless for a single fat commit. Cheap for the worker to try once before permafailing, but don't expect it here.
3. Manual runbook: the CLI's --target-max-pack-bytes set near the server cap rescues this repo today with zero code changes (temp-ref checkpoints persist; subsequent worker syncs are incremental/replicate). Or temporarily raise entiredb's body limit for one repo.
4. Object-level splitting: possible in principle (push oversized blobs first in their own packs anchored by temp refs pointing directly at blob OIDs — refs to non-commit objects are legal git and keep receive-pack connectivity checks satisfied; then trees+commit; GitHub serves blob-OID wants for partial-clone backfill). But it needs client-side object enumeration (filtered fetch + tree walking à la ExtractCommitParents) and entiredb cooperation on non-commit refs/GC. The in-memory materialized strategy is capped at 500k objects and would OOM here (materialized.go:40). Only warranted if you observe single-commit packs exceeding the server's own limit — that's the only case options 1–3 can't cover.

Your four steps — verdict and two bugs you missed

1. Suspend now: correct. Also purge queued redeliveries. Each retry currently costs ~10 GiB GitHub egress + ~10 GiB entiredb ingress (chunked body, so the server can only cut at the 10 GiB mark) + ~486 MiB batch abort.
2. Directionally right, with the corrections above. Biggest risk: it may not converge this repo (measure c0 first), and by itself it never helps a repo that enters batching without a one-shot rejection.
3. Right idea, wrong trigger if done by error text. The line-625 return is shared with genuinely transient failures (network, 500s); and errors.Is(…, ErrPackUploadAborted) likely doesn't survive the net/http request-body→response-error plumbing (the in-process code deliberately uses observer.Aborted(), not error matching). Export a sentinel from git-sync at the bottomed-out branch specifically (subdividable error + expansion didn't grow), and only mark permanent when the server rejected the indivisible pack (per Q2's rule) — otherwise plan #3 will permafail repos that plan #2 (or a config change) would fix. Ship #2 strictly before #3, and remember "permanent" is config-relative: invalidate the failure index on git-sync deploys or entiredb limit changes.
4. Fine, plus one concrete bug: on bootstrap failure, bootstrapWithInputs returns Result{} (syncer.go:1404), discarding the populated bstrap.Result (RelayMode, RelayReason, BatchCount, TempRefs) — the worker cannot log strategy-on-failure today even if it wants to. Propagate bResult fields alongside the error.

Missed bug A (why the doomed one-shot happens at all): lookupGitHubRepoSizeKB (bootstrap.go:1345–1378) sends the api.github.com request with no auth — ApplyAuth is never called, and auth lives per-request, not in the transport (smarthttp.go). For private repos it 404s, githubBatchLimit silently no-ops, and every fresh attempt on a large private repo does the full ~10 GiB doomed one-shot before falling back. (Even for public repos, unauthenticated api.github.com is 60 req/hr/IP — this preflight is near-dead in prod.) Fixing it is cheap and saves ~10 GiB per attempt. Interaction warning: once fixed, this repo goes straight to batching at 512 MiB and never sees the announced 10 GiB — so autoTargetMaxPackBytes never runs and your fix #2 never fires. The preflight-auth fix makes the bottom-out ceiling fix (Q2) mandatory, not optional.

Missed bug B: the ratchet-down-only selfImposedBudget described under Q2 — the announced limit can never raise the in-loop ceiling, in either code path.

Sequencing I'd use: (1) suspend + purge; (2) measure the repo's per-checkpoint pack sizes; (3) unblock prod now via manual CLI --target-max-pack-bytes near the server cap; (4) ship fix #2 corrected (both-directions derived + ceiling) plus the bottom-out server-verdict retry; (5) preflight auth fix; (6) permanent-failure sentinel + worker classification; (7) telemetry/Result-on-error fixes any time.

ok sounds good

14 findings on PR #118 (xhigh effort, d4649ff1). The three that block: the !subdivide gate is inverted so any transient error (401, reset, 500, timeout) on an indivisible checkpoint gets the permanent sentinel; a genuine 413 can never reach that sentinel at all; and the relaxed budget leaks to every later checkpoint and branch. Findings 1 and 3 were reproduced with a throwaway probe — the existing suite catches none of them (go build, the touched packages' tests, and lint are all clean).

Another Claude session sent a message: <cross-session-message from="uds:/tmp/cc-socks/74505.sock" from-name="ent-2054-cb" from-mode="prompting"> Code review of entireio/git-sync PR #118 (commit d4649ff1, branch nodo/ent-2060-bottom-out-server-verdict) found 14 issues — 3 are blockers. Repo at /Users/nodo/work/tasks/ENT-2054/git-sync; all line numbers are repo-relative at that commit. go build, the touched package tests, and golangci-lint are all clean, so nothing below is caught by the existing suite. Findings 1 and 3 were reproduced with a throwaway probe test.

BLOCKERS

1. bootstrap.go:686 — the !subdivide disjunct is inverted relative to its own comment. subdivide is true for real size rejections and false for everything else, so ANY unrelated push error on an indivisible checkpoint gets classified as the permanent ErrCheckpointExceedsTargetLimit. Probe: a 1-commit chain whose PushPack returns errors.New("http 401 unauthorized") yields push bootstrap batch for refs/heads/main: bootstrap checkpoint exceeds target pack limit and cannot be subdivided further: http 401 unauthorized after 1 push. Same for connection reset, HTTP 500, pre-receive hook decline, context deadline. Every single-commit repo — and every checkpoint after subdivision bottoms out on a large repo — permafails on a transient error, telling the mirror worker to stop redelivering a repo that only needed a retry. Opposite of the PR's stated direction.

2. bootstrap.go:679 — a genuine 413 body-limit rejection can never reach the sentinel. subdivide is true and the relaxed-retry block requires abortedEarly, so relaxedRetried stays false and the gate at 686 is skipped. Probe: a 1-commit chain whose PushPack returns http 413: body exceeded size limit 1000 returns the plain retryable error, no sentinel, after 1 push. A repo whose first checkpoint push gets a hard 413 with no prior self-imposed abort stays in the redelivery loop forever — the exact failure mode this PR exists to end. The sentinel only ever fires after a self-imposed abort has already happened.

3. bootstrap.go:676 — selfImposedBudget = p.AnnouncedTargetLimit mutates the function-scope variable declared at line 366 and never restores it, so the raised ceiling leaks to every later checkpoint and every later branch. Target announces 10 GiB, TargetMaxPack 512 MiB: checkpoint 7 bottoms out, retries at 10 GiB, succeeds — for checkpoints 8..N and all later branches the abort ceiling is now 10 GiB while the pre-flight estimate still plans against 512 MiB, so a pack the estimate calls 400 MiB but which is really 4 GiB uploads in full instead of aborting at ~486 MiB. Breaks the "bounds the waste of a doomed push" invariant the PR claims to keep. It also silently disables the fix for branch 2+: relaxedRetried resets per branch but the budget does not, so p.AnnouncedTargetLimit > selfImposedBudget is then false — no retry and no permanent classification.

CORRECTNESS

1. bootstrap.go:1268 — isIndivisibleCheckpoint derives prev from batch.Checkpoints[idx-1] instead of the loop's current, measuring the wrong gap on the stale-temp-ref re-plan path. Lines 397-413 replace batch.Checkpoints with evenCheckpoints(remaining, ...) and set startIdx = 0 while current = batch.ResumeHash; at idx 0 it uses prev = plumbing.ZeroHash, so subdivideCheckpoints sees curIdx = -1 and a gap counted from the chain root instead of from ResumeHash — reporting "divisible" for a checkpoint subdivideToFactor just proved indivisible. After the relaxed retry has fired and failed you get a plain retryable error instead of the sentinel, on exactly the resume route ENT-2054 is about. Pass current in.

2. bootstrap.go:571 — the loop parses parsedLimit := targetBodyLimit(pushErr) on every rejection but never feeds it into p.AnnouncedTargetLimit, which is populated only on Execute's one-shot auto-switch path (line 232). With --target-max-pack-bytes set (or once the GitHub large-repo preflight at 1408 works), Execute reaches executeBatched at line 168 without ever attempting a one-shot push, so AnnouncedTargetLimit is 0 for the whole run: every in-loop 413 announcing 10 GiB is parsed, used for limit and nextSelfImposedBudget, then discarded — the relaxed retry can never fire. if parsedLimit > p.AnnouncedTargetLimit { p.AnnouncedTargetLimit = parsedLimit } makes it self-sufficient and drops the landing-order coupling the PR description has to warn about.

3. bootstrap.go:779 — result.Batching = true and result.RelayMode = "bootstrap-batch" are assigned only at executeBatched's success return, so every failure path returns Batching=false / RelayMode="bootstrap". That falsifies the syncer change's premise that Execute "populates these before it can fail": a failed batched bootstrap is indistinguishable from a failed one-shot one, the very distinction the syncer change was added to expose. And Result.Lines() (internal/syncer/syncer.go:221) gates the temp-ref line on r.Batching && len(r.TempRefs) > 0, so the TempRefs the new error-path Result carries out are still never rendered. Set both on result before the batch loop, next to result.Relay.

4. internal/syncer/syncer.go:1409 — the carried-out strategy facts are discarded one layer up by every public entry point, so the change has no observable effect. client.go:73 (return SyncResult{}, fmt.Errorf("sync: %w", err)), client.go:57 (Plan), unstable/client.go:150/167/186/200 all replace the Result with a zero value on error; cmd/git-sync/syncplan.go:81 returns before printOutput. The real consumer, mirror-pipeline cmd/worker/syncer.go, only calls reportSyncSuccess on the success path. The fleet-wide log query the PR wants still returns nothing — the fix has to reach the client wrappers, or the syncer must log the route itself.

5. bootstrap.go:665 — the retry condition compares the announced limit against selfImposedBudget without distinguishing "the budget we chose" from "a server cutoff we measured". A proxy that cuts at 4 MiB with no announced limit ratchets selfImposedBudget down to 4 MiB via nextSelfImposedBudget (line 1224); the next push aborts at 4 MiB, subdivision bottoms out, and since AnnouncedTargetLimit (10 GiB from the original one-shot 413) > 4 MiB the retry jumps the ceiling from a measured 4 MiB straight to 10 GiB — uploading up to ~9.5 GiB against a server that demonstrably cuts at 4 MiB before the abort engages. Track whether the budget came from a ratchet-down observation and skip the retry when it did.

6. bootstrap.go:99 — ErrCheckpointExceedsTargetLimit is unexported from the root gitsync package, so the caller its doc comment addresses cannot match on it. errors.go aliases every caller-facing sentinel (ErrTargetRefMoved, ErrNoRefsSelected, ErrSourceEmptyUnverified, ErrTargetEmptyUnverified, ErrSourceEmptyTargetPopulated) into package gitsync with a "Test for it with errors.Is" doc block, and mirror-pipeline cmd/worker/syncer_errors.go:225-263 matches exactly those. The internal bootstrap package is unimportable from mirror-pipeline, so "callers can treat that as permanent" is unreachable — the worker would have to string-match, which errors.go:20 explicitly warns against. Add the alias plus doc block in errors.go.

7. internal/syncer/syncer.go:1409 — the error-path Result is asymmetric with the success path: it drops Plans, Pushed, Warned and Measurement even though Execute sets result.Plans = plans at line 164, before any failure is possible (the same argument the new comment makes for Relay/RelayMode). fromSyncResult (results.go:186) then yields Refs: [] and Measurement: {} for a failed bootstrap while the success branch at 1421 carries both.

QUALITY / TESTS

1. bootstrap.go:1259 — isIndivisibleCheckpoint's doc contradicts its implementation and it rebuilds a full chain-index map to answer what is one subtraction. The comment says it "reports whether the checkpoint at idx covers a single commit", but subdivideCheckpoints splits every remaining gap, so it returns true only when the entire remaining tail is one-commit-per-gap — a 1-commit checkpoint followed by a 20-commit gap answers false, making the sentinel's firing condition depend on unrelated later checkpoints and amplifying finding 1's unpredictability. The intended answer is chainPosition(chain, batch.Checkpoints[idx]) - chainPosition(chain, current) == 1, correct by construction and avoiding a map[plumbing.Hash]int over the whole chain (~1M inserts for a linux-sized repo) on every push failure. Also len(batch.chain) == 0 at line 686 is dead — isIndivisibleCheckpoint already returns false for an empty chain.

2. bootstrap_test.go:1762 — all three new tests share one shape (single branch, 1-commit chain, budget far below minBytesBeforeAbort), so none can catch the budget leak, the multi-branch regression, or the projection-based abort production actually hits. Budgets are 64, 256 and 1<<20 bytes while minBytesBeforeAbort is 8 MiB (line 1136), so only the absolute bytesSent >= threshold branch of shouldAbortPush ever fires — never the projection path that produced the production log line the PR quotes. The fake pack is "PACK" + 4096x'x', whose version field is 0x78787878, so packfile.Scanner rejects it and the observer's totalObjects/objectsSent stay 0 while checkPackSizeAndSubdivide reads the count anyway and gets 2,021,161,080. A two-checkpoint or two-branch case asserting the budget is restored after a relaxed retry is the test that would have caught finding 3.

3. bootstrap_test.go:1765 — bottomOutParams writes the same 1-commit chain into two throwaway stores and relies on the hashes matching across calls: makeLinearCommitChain(t, 1) builds one store, then fetchCommitParents builds a second memory.NewStorage() and calls writeLinearCommitChain(t, store, 1) again, so DesiredRefs.SourceHash and the parent map only agree because that helper happens to be deterministic. If it ever picks up a real timestamp the three tests fail with an unrelated "checkpoint not in chain" symptom. Build the store once, derive both from it, and drop the single-valued packBytes parameter (4096 at all three call sites).

4. bootstrap.go:677 — the relaxed retry continues back through packReaderForCheckpoint, re-fetching the entire indivisible pack from the source rather than reusing the stream it just uploaded. For the case this branch exists to serve (one commit whose pack is several GiB) that doubles source egress and wall time before the target gives a verdict. Unavoidable without buffering, but worth stating in the comment alongside the "bounds the waste" rationale.

Another Claude session sent a message: <cross-session-message from="uds:/tmp/cc-socks/74505.sock" from-name="ent-2054-cb" from-mode="prompting"> Verified 703d9dac independently — all three blocker fixes hold, and I mutation-tested two of the new regression tests rather than taking them on trust.

Blocker 1: confirmed by structure, not by test. The terminal block now sits inside if subdivide && len(batch.chain) > 0 (line 590), and a non-size error makes subdivide false, which skips the entire block and falls through to the plain error at 741. The inner condition is unreachable for those errors, so there is no mutation that reintroduces the bug without moving the block back out — which is the right shape for the fix, and it is why your || true injection stayed green. Good catch on your own probe being invalid.

Blocker 2: mutation-verified. Dropping the disjunct back to if relaxedRetried { makes TestExecuteBatchedHardRejectionIsPermanentWithoutSelfImposedAbort fail with a hard body-limit rejection on an indivisible checkpoint must be permanent, got push bootstrap batch for refs/heads/main: http 413: body exceeded size limit 1000.

Blocker 3: mutation-verified. Re-adding selfImposedBudget = p.AnnouncedTargetLimit next to the relaxedBudget assignment makes TestExecuteBatchedRelaxedBudgetDoesNotLeakToLaterCheckpoints fail with exactly the aborts=[1] err=<nil> you described. The per-attempt shape is right: budget reads relaxedBudget at 555-557 without writing back, and both it and relaxedRetried clear on checkpoint advance at 773-774. I also checked nextSelfImposedBudget returns current unchanged when abortedEarly, so a relaxed attempt's large sentBytes cannot ratchet the budget upward — finding 8's budgetFromObservation guard is not load-bearing for that case, which is a good property.

Tree restored clean; go test ./internal/strategy/bootstrap/... ./internal/syncer/... green at 703d9dac.

On the declined item — I'll argue, because the multi-MiB premise does not hold. totalObjects comes from observer.TotalObjects() (line 567), i.e. the parsed 12-byte pack header count, not from the body's actual size. And bootstrap_test.go already has makePackHeader(objectCount uint32) at line 383 building a valid "PACK" + version 2 + count header. Today's fixture at line 1774 is append([]byte("PACK"), bytes.Repeat([]byte("x"), 4096)...), whose version field is 0x78787878, so the scanner rejects it and totalObjects stays 0 — that zero, not the pack's size, is what closes the abortedEarly && totalObjects > 0 && effObjectsSent > 0 gate at 657. Swap in makePackHeader(N) and effectiveObjectsSent (1211-1212, the objectsSent == 0 && totalObjects > 0 && abortedEarly case) unlocks the projection at 658 with a fixture no larger than the current one. shouldAbortPush's own projection at 1240 additionally needs objectsSent > 0, so that one wants a single real object in the body — still not multi-MiB.

Where I do concede: the projection only sizes the next subdivision, so this is not a blocker and the three new tests are valid for what they assert. But the fixture change is two lines against a helper already in the file, and the current state has checkPackSizeAndSubdivide reading an object count of 2,021,161,080 off the garbage version field — so those tests pass partly for reasons unrelated to the paths they name. Worth doing while you are in here; your call on whether it lands in this PR or a follow-up.

One new minor thing, no action needed if you disagree: at 603-604, when a relaxed retry aborts early, limit is taken from selfImposedBudget rather than the relaxedBudget actually in force for that attempt, so the limit_bytes log field under-reports the ceiling on precisely the path this PR added for diagnosability. No functional impact — the checkpoint is indivisible by then, so observedSubdivisionFactor cannot expand anything regardless. </cross-session-message>

Another Claude session sent a message: <cross-session-message from="uds:/tmp/cc-socks/74505.sock" from-name="ent-2054-cb" from-mode="prompting"> No — don't build a fixture for shouldAbortPush's projection branch. It's already covered directly, and better than an integration fixture would cover it.

TestShouldAbortPush at bootstrap_test.go:633 is a table test calling the function with (bytesSent, objectsSent, totalObjects, budget) straight, and it already includes "projection under threshold proceeds" (25/100), "front-loaded projection trips abort" (5/100), and "near-end matched ratio projects to current bytes" (98/100, the anti-flap case). That's the arithmetic at 1240 exercised across the interesting ratios, without a packfile at all. Threading a real object through executeBatched to reach the same branch would re-test arithmetic that has better coverage as a pure-function table, and would be more fragile doing it.

The one genuine residual gap is wiring, not arithmetic: nothing asserts the observer actually feeds a non-zero objectsSent into the aborter callback during a real push. If you want that, the cheap form is asserting the callback saw objectsSent > 0 at least once — not crafting a pack that trips an abort. Optional, and a follow-up at most; I wouldn't hold the PR for it.

Verified 753c36bd: limit = budget at the abortedEarly branch, makePackHeader hoisted to package scope at line 387, and go test ./internal/strategy/bootstrap/... ./internal/syncer/... green. Fair correction on the closure — it was local to TestCheckPackSizeAndSubdivide and I described it as if it were reusable; hoisting it with the comment about the failure mode being invisible is the better fix, and I agree that comment is the durable part.

Nothing further from me. All 14 findings are addressed or consciously closed. </cross-session-message>

can you summarize this change in simple term

can you run another adversarial review?

Verdict: not production-safe to roll out as sequenced. The core idea (one relaxed retry, then a permanent sentinel) is sound, but the sentinel fires on evidence that is not a server size verdict in two reachable shapes, the deploy ordering turns the new terminal state into an expensive infinite retry loop, and the observability the change claims to add never reaches production. Tracked tests pass (go build ./... && go test ./... green); note two untracked probe files (internal/strategy/bootstrap/zz_probe_test.go, zz_probe2_test.go) appeared in the working tree during my review — I did not create them, but I verified their fixtures against the code and they empirically confirm findings F1/F2/F7 below. I modified no tracked files.

Production context established from code: worker AckWait 15 min with InProgress extends every 5 min, MaxDeliver 10, Nak delay 30 s, sync budget 30 min (/Users/nodo/work/tasks/ENT-2054/mirror-pipeline/cmd/worker/consumer.go:24-44); rekicker re-drives max_deliveries entries every 15 min and skips only permanent (cmd/rekicker/metrics.go:16,37); entiredb's cap is 10 GiB announced as body exceeded size limit 10737418240 (docs/runbooks/mirror-stuck-refs-without-objects.md:22-25); the worker pins git-sync at the merge-base (go.mod:7), so this change ships inside the next worker image.

F1 — HIGH: a single transient 408/504 on an indivisible checkpoint is classified as a permanent size verdict

/Users/nodo/work/tasks/ENT-2054/git-sync/internal/strategy/bootstrap/bootstrap.go:737-741 — the terminal branch is relaxedRetried || isBatchableTargetPushError(pushErr), and isBatchableTargetPushError includes 408/504 deadline errors (bootstrap.go:1600-1617). Probe-confirmed: one "http 504" with zero bytes sent on a 1-commit checkpoint returns ErrCheckpointExceedsTargetLimit on the first push. Scenario: any batched bootstrap sitting at a single-commit gap (natural for one-commit branches; guaranteed after subdivision) catches one gateway 504 during an entiredb rolling restart. Today that's retryable and heals next delivery. Once the worker maps the sentinel to Term, every target brownout mints permanent failure-index records the rekicker deliberately skips — each needs manual mirrors resume per the runbook. Fleet-wide, one entiredb deploy per region can permafail every in-flight large bootstrap. Fix: make the sentinel require a parsed body-limit rejection (isTargetBodyLimitError), never a bare deadline with no size evidence.

F2 — HIGH: the "server verdict" is usually git-sync's own 95% heuristic; packs the server would accept get permafailed

The relaxed retry keeps the aborter armed at budget = announced with safety = 95 (bootstrap.go:553-563, shouldAbortPush at :1228-1250). The retry therefore can never deliver a pack in (0.95×announced, announced] — it self-aborts at ~9.7 GiB against entiredb's 10 GiB cap and then relaxedRetried makes the failure terminal. Probe-confirmed: pack 4108 B, announced 4200 B → permanent, no server contact past 95% (the control probe with headroom converges). The projection path can also abort far below the limit on blob-front-heavy packs. Consequence: the sentinel's own doc ("always carries a verdict from the target", /Users/nodo/work/tasks/ENT-2054/git-sync/errors.go:94-110) is false in the dominant shape — for any pack > 10 GiB the absolute/projection abort fires before the server can answer, so the terminal error wraps pack upload aborted early… (pack_observer.go:19), not body exceeded size limit. Fix: disable the aborter (or use safety=100 + slack) on the relaxed attempt, and/or require a real 413 in the final error before returning the sentinel.

F3 — HIGH (rollout window + cost): until the worker learns the sentinel, the new terminal state is transient — a 10-redelivery, rekicker-forever loop that re-pays the relaxed retry every attempt

The worker classifies by substring today (cmd/worker/syncer_errors.go:359-401): the 413-wrapped shape would Term (hint body exceeded size limit), but per F2 the common shape wraps the abort error → no hint → Nak → 10 deliveries → max_deliveries → rekicked every 15 min indefinitely. Cost per relaxed attempt: pack re-fetched from source and streamed to target until abort — ~8–100 MiB when objects flow (projection cuts early, minBytesBeforeAbort = 8 MiB), but up to ~9.7 GiB fetched + pushed for single-giant-blob packs (objectsSent stays 0, only the absolute 95% trigger fires). Worst case ≈ +9.7 GiB and +2–4 min per delivery, ≈ +97 GiB per 10-delivery cycle, recurring every ~15–30 min → TB/day scale for one stuck repo, paid as source-cluster egress (cross-region for entiredb→entiredb) plus target ingest. GitHub egress is exposed only when the repo-size preflight API call fails (rate limit/outage → lookupGitHubRepoSizeKB false, bootstrap.go:1495-1529) and the one-shot 413 path arms the retry. Fix: ship the worker-side errors.Is(ErrCheckpointExceedsTargetLimit) classification in the same release as the go.mod bump — or gate the relaxed retry behind a Params opt-in the worker sets only once its classifier ships.

F4 — MEDIUM: timeout interplay is survivable but can starve the verdict forever

The InProgress extender (5-min cadence vs 15-min AckWait) covers the longer push; concurrent redelivery still requires extend failures (pre-existing risk, but exposure window grows ~20× at 9.7 GiB vs 486 MiB). If two workers do overlap, checkpoint pushes are CAS'd on the temp ref (stagePlans sets TargetHash: current, bootstrap.go:478-494) so the loser fails cleanly — wasted transfer, no corruption. The sharper issue: if the 30-min sync budget expires mid-relaxed-retry, the worker explicitly wraps it transient (consumer.go:426-434) — so a repo whose one-shot-reject + re-subdivision + relaxed retry doesn't fit in 30 min never reaches any verdict on any delivery and lives in the F3 loop even after both halves ship.

F5 — MEDIUM (server side): the retry reintroduces the exact oversized-POST shape the runbook documents as a repo-wedging incident

Before this change the batched path capped every receive-pack body at ~486 MiB; only the one-shot path ever hit the 10 GiB cap — and the runbook (docs/runbooks/mirror-stuck-refs-without-objects.md) documents that a push rejected at that cap can leave "refs present but 0 B / 0 objects", requiring manual entiredbctl admin reset-repo-data. The relaxed retry deliberately sends up to ~10 GiB from inside batched mode, and on the final checkpoint that POST carries the real branch-create command (bootstrap.go:484-494) — the wedge's shape. Also a 10 GiB single-request ingest is a step change in replication/repair load per push for the entiredb cluster. Ask an entiredb owner to confirm a rejected near-cap POST cannot recreate the refs-without-objects state before enabling this fleet-wide.

F6 — INFO: the fix doesn't reach the dominant source kind

AnnouncedTargetLimit is only learned by parsing a rejection (bootstrap.go:229-236, 590-598, 1635-1650). GitHub-kind repos ≥1.5 GB enter batching via the preflight with no rejection, and batched pushes never exceed ~486 MiB, so the limit is never announced → the relaxed retry never arms → a GitHub repo with a >512 MiB indivisible commit still loops max_deliveries + rekick exactly as today. Not a regression; but ENT-2060's fix is effectively scoped to entiredb→entiredb mirrors.

F7 — LOW: the observability this change was written to provide never reaches Datadog

All the new decision logs (bootstrap batch retrying indivisible checkpoint…, bootstrap.go:718-724) go through p.log, which requires a logger that only exists under cfg.Verbose (internal/syncer/syncer.go:826-829) — and the stable client the worker uses has no Verbose knob (only unstable/client.go:39 does). The p.notice lines fall back to raw os.Stderr (syncer.go:737-742): unstructured, no ULID. And the syncer.go error-path Result enrichment (syncer.go:1401-1419) is inert — the worker discards Result on error (cmd/worker/syncer.go:443-448 path; only reportSyncSuccess reads it) and the CLI does too (cmd/git-sync/syncplan.go:81-84). Operators can distinguish the new failure only by grepping sentinel text in span error.message/failindex LastError. Probe 4 also shows a batched run failing during checkpoint planning still reports Batching=false/RelayMode="bootstrap", contradicting the in-diff comment. Fix: worker-side log of Execution fields on the error path + a span attribute for relaxed-retry/sentinel.

F8 — LOW: budgetFromObservation is per-branch while selfImposedBudget is per-run

bootstrap.go:456-467 declares the guard inside the per-batch loop; a measured, unannounced server cutoff learned on branch A is forgotten on branch B, whose bottom-out can then relax-retry past a demonstrated cutoff — the exact case the flag exists to prevent (comment at :697-703). Only affects middleboxes that cut without announcing; entiredb announces, so low.

Checked and dismissed

Populated-Result-on-error in client.go/unstable/client.go (all consumers discard it — safe, just unused); relaxed budget leaking to later checkpoints (reset at idx++, covered by the shipped test); infinite relaxed-retry loop (relaxedRetried latches); errors.Is through the wrap layers (verified); sentinel text colliding with worker substring hints (none — pre-ship dispositions are unchanged); our own sync-deadline mid-retry producing a false permanent (worker wraps it transient explicitly; context errors aren't "batchable"); in-process 8× retry amplification (maxSyncAttempts loop breaks on anything but transient 404s, cmd/worker/syncer.go:449-451).

Minimum bar to ship: fix F1 and F2 in git-sync (sentinel only on a genuine parsed 413), and land the worker-side sentinel classification in the same worker release as the go.mod bump. F5 needs an entiredb owner's sign-off before the relaxed ceiling is allowed to approach the server cap.</result> <usage><subagent_tokens>200593</subagent_tokens><tool_uses>41</tool_uses><duration_ms>967621</duration_ms></usage> </task-notification>

The relaxed retry never actually lets the server decide — it self-aborts at 95% of the announced limit (or on a projection) and that self-abort is classified permanent. internal/strategy/bootstrap/bootstrap.go:555-563 installs the same shouldAbortPush aborter on the retry attempt with budget = relaxedBudget, so the retry cuts at 95% of the announced limit (bootstrap.go:1232-1233) or, past 8 MiB, whenever bytesSent × totalObjects ÷ objectsSent projects over that threshold (bootstrap.go:1240-1245). The terminal classification relaxedRetried || isBatchableTargetPushError(pushErr) (bootstrap.go:739-742) then treats that self-abort as the target's verdict. Demonstrated by probe: a 4108-byte pack with announced limit 4200 — a pack the server would accept, proven by a control run with headroom that succeeds — fails with ErrCheckpointExceedsTargetLimit wrapping pack upload aborted early: projected to exceed target body limit, i.e. the "server verdict" sentinel wrapping git-sync's own abort. This directly contradicts errors.go:106-109 ("this sentinel always carries a verdict from the target rather than from a threshold git-sync chose") and the user-facing notice ("retrying at the target's own limit"). The projection variant is the practical killer: pack ordering that front-loads large blobs — precisely the giant-commit repos this feature exists for — makes the early bytes/object average overshoot, so a pack genuinely under the announced 10 GiB can be aborted at a small fraction of it and permanently classified. Net effect: repos that would sync are marked permanent and redelivery stops — strictly worse than the pre-change behavior (retryable hard failure). Fix direction: on the relaxed attempt, abort only at ≥100% of the announced limit and disable the projection path; or classify terminal only when isBatchableTargetPushError(pushErr) (real server response) or sentBytes >= announced.

2. A single transient 408/504 on an indivisible checkpoint is classified permanent — even with zero bytes uploaded. isBatchableTargetPushError includes 408/504 (bootstrap.go:1600-1614), and the terminal branch accepts it with no retry of any kind (the relaxed retry requires abortedEarly, false here). Demonstrated by probe: a single-commit repo (indivisible from the first push — the fresh-import mirror case) whose one push returns http 504 gateway timeout before reading any of the pack (sentBytes=0) fails immediately with ErrCheckpointExceedsTargetLimit; same for 408. A 504 is availability/time-dependent (gateway hiccup, backend deploy), not a size verdict — with 0 bytes sent there is literally no size evidence. This also contradicts the block's own comment at bootstrap.go:697-700 ("an unrelated push error (auth, 5xx, reset, hook decline) never reaches here and stays retryable") — 504 is a 5xx and does reach it. Callers permanently stop redelivering a repo one calm retry would have mirrored.

3. The "route facts before any of it can fail" invariant is false for planning-phase failures. result.Batching = true; result.RelayMode = "bootstrap-batch" (bootstrap.go:337-341) is set after the SupportsBootstrapBatch check (307-309) and after planBatches (327-335), which performs the FetchCommitParents streaming fetch — the most failure-prone step for exactly the large repos that batch. Demonstrated by probe: a batched run whose commit-graph fetch fails reports Batching=false, RelayMode="bootstrap" on the error path — the "failed batched bootstrap reportable as a failed one-shot one" state the new comment says must not happen, defeating the ENT-2054 observability goal for that failure class. (BuildBootstrapPlans failure in Execute at bootstrap.go:166-168 is worse: it returns a zero Result{}, losing even Relay/RelayMode.) Fix: set the two fields before planBatches/the support check.

4. unstable.Client.Bootstrap still discards the populated result on error. unstable/client.go:200-203 returns Result{} on error while Plan/Sync/Replicate in the same file were updated to return result. syncer.Bootstrap deliberately hands back the populated result with the error (syncer.go:1320-1322); the one API method actually named "bootstrap" throws it away — the observability half of the change doesn't reach its most on-topic entry point.

Test-suite findings (mutation-verified)

• Both AnnouncedTargetLimit capture sites are untested. Deleting the one-shot capture (bootstrap.go:232-234) and the in-loop capture (bootstrap.go:597-599) passes the full suite. These are the only production sources of the announced limit — syncer.go:1394-1403 never sets Params.AnnouncedTargetLimit; every end-to-end test injects it directly via Params (bootstrap_test.go bottomOutParams), a path production never takes. Either capture could regress and the feature would go silently inert with green CI.
• The budgetFromObservation guard is untested. Forcing it to false at bootstrap.go:648 passes the full suite — the protection the change's longest comment defends ("jumping past a measured cutoff would upload gigabytes into a server that demonstrably cuts far earlier") has no coverage. A probe confirmed the scenario is reachable (partial-drain unparseable 413, then an indivisible self-abort) and that the guard does work — it's purely a coverage hole.
• The entire syncer error-path carry is untested. Reverting syncer.go:1409-1418 to return Result{}, ... passes the full suite (nothing under internal/syncer, client.go, or unstable/ asserts a failed run's Result fields). Half the change has zero regression protection.
• Positive controls: removing relaxedRetried || from the terminal condition and removing the relaxedBudget = 0 reset at bootstrap.go:776-778 each break the new tests — the retry-core tests are real and bite.

Checked and found sound

No-progress/infinite-loop: every continue either strictly expands checkpoints, sets relaxedRetried, or advances idx; arming requires the gap at idx to be 1, and no subdivision can replace Checkpoints[idx] while armed (a 1-commit first gap never gets a midpoint), so relaxedBudget cannot leak onto a different checkpoint. The append(batch.Checkpoints[:idx], expanded...) aliasing is safe (subdivide always allocates; the bottom-out return aliases the input but that branch skips the append). Stale-temp-ref resume + relaxed retry converges correctly (probe passed: re-plan from ResumeHash, arm on the 1-commit gap measured against current, succeed). errors.Is works through the %w: %w double wrap and the syncer/client wraps (probe passed; Go 1.26). measurementDone double-call is once-guarded and memoized; stats.snapshot() deep-copies. Two minor notes, precisely bounded: budgetFromObservation is declared per-branch (bootstrap.go:465) while the selfImposedBudget it describes is cross-branch (line 372), so branch 2 can arm a retry past a cutoff measured on branch 1 (waste bounded — the server re-cuts, classification still ends correct); and when the announced limit is learned from an in-batching 413 that is ≤ the budget, the ratchet makes them equal so the strict > at bootstrap.go:718 can never arm — packs in the 95–100% band of such a limit remain stranded retryable-forever (the pre-existing self-imposed-abort stranding this change set out to end, unfixed in that configuration; same root cause as defect 1: the 95% margin is applied to the announced limit too).</result> <usage><subagent_tokens>197801</subagent_tokens><tool_uses>51</tool_uses><duration_ms>1277238</duration_ms></usage> </task-notification>

thoughts on simplifying this change?

can you ask a Fable subagent for advice?

1. Is deciding up front equivalent-or-better? Yes, with two corrections

I walked every divergence candidate you listed:

• Stale-temp-ref resume (bootstrap.go:403-424): isIndivisibleCheckpoint (bootstrap.go:1349) already measures against current, not Checkpoints[idx-1], precisely for the startIdx=0 re-plan. The up-front design uses the same helper per iteration. No divergence.
• Pre-flight checkPackSizeAndSubdivide changing indivisibility mid-iteration: it can only take a divisible gap toward indivisible, and it exits via continue, so the ceiling is recomputed on re-entry. Also note subdivideCheckpoints splits all remaining gaps — a 1-commit current gap with wide later gaps still triggers pre-flight subdivision, but expanded[0] equals the current checkpoint, so on continue the same span is refetched and correctly re-classified indivisible. Identical in both designs.
• recombineDropCount: runs only after success and only widens gaps; a big successful push at the announced ceiling has sentBytes ≥ target/2 so dropCount=0 (bootstrap.go:1189-1206). No interaction.
• Subsumed branches: skipped before the checkpoint loop (bootstrap.go:379-394), never reach the observer. No interaction.
• False-positive risk of the up-front indivisibility check: isIndivisibleCheckpoint and subdivideCheckpoints compute the same gap over the same chain and current, and nothing mutates either between push and failure handling — so atAnnounced ⇒ subdivideToFactor will bottom out is airtight. The terminal classification atAnnounced && abortedEarly can never mark a splittable span permanent.

Two things you must carry over correctly:

(a) > must be >=. HEAD's gate is p.AnnouncedTargetLimit >= effBudget with an explicit comment why (bootstrap.go:732-737): when an in-batching 413 parse ratchets selfImposedBudget down, budget and announced end up equal, and the escalation's only value is shedding the 5% margin/projection. With your >, an indivisible pack sized between 95% and 100% of the announced limit self-aborts at 95%, isn't atAnnounced, returns retryable — and every future delivery repeats identically. That's a permanent livelock on a pack that fits. HEAD handles it; your sketch regresses it. One-character fix, and TestExecuteBatchedRelaxedRetryHasNoSafetyMarginAtAnnouncedLimit (bootstrap_test.go:1983) encodes the intent and should catch it if the rewrite preserves that test's spirit.

(b) budgetFromObservation stays a cross-iteration flag. At the point of use you cannot distinguish "budget < announced because a proxy silently cut us at 30 MiB" from "budget < announced because TargetMaxPack is deliberately small" — the latter is the normal feature-enabling state. The flag is set only in the failure branch (bootstrap.go:663) and consumed on a later attempt. It survives as state. But hoist it out of the per-branch scope: HEAD declares it inside the batch loop (bootstrap.go:467) while selfImposedBudget spans branches (bootstrap.go:374). So a budget measured from a real server cutoff on branch 1 carries to branch 2 with its provenance erased, and branch 2's indivisible checkpoint will jump past a measured cutoff — violating the invariant HEAD's own comment states ("must not... upload gigabytes into a server that demonstrably cuts far earlier"). That's a live scoping bug in HEAD, third of the same species as the leaked-ceiling one. Provenance must live with the value. The simplification is the natural moment to fix it.

Also keep: the in-loop AnnouncedTargetLimit ratchet (bootstrap.go:612-616), the isTargetBodyLimitError terminal for indivisible checkpoints pushed at the small budget (the announced=0 and observation-guarded cases still need it), and a notice when raising ("cannot split further (1 commit) — pushing at the target's announced limit X"), or the operator sees an unexplained multi-GiB upload — the legibility that commit 753c36bd bought.

2. The cheap first attempt — your instinct is right, and the counter-worry is a category error

A ceiling is an abort threshold, not an upload size. A pack that fits under 512 MiB uploads exactly the same bytes under a 10 GiB ceiling; the ceiling only matters for packs bigger than it. So "small attempt succeeds, simplification uploads at a huge ceiling unnecessarily" describes zero extra bytes. Enumerate:

• Pack < 95%·budget, no projection trip: identical bytes either way.
• Pack fits budget but the projection fires falsely (front-loaded giant blob — exactly the shape here; shouldAbortPush, bootstrap.go:1253): shipped burns an abort + refetch + relaxed retry; up-front just succeeds. Up-front is better, not merely equal.
• Pack ∈ (budget, announced]: shipped pays a doomed ~487 MiB upload + a second full source fetch, then succeeds; up-front succeeds in one pass. This is the feature's primary success path.
• Pack > announced: shipped pays ~0.5 GiB + 10 GiB before terminal; up-front pays 10 GiB. Both classify identically.

There is no branch where the small attempt saves anything on an indivisible span — "doomed under the small ceiling" has no remedy but the big ceiling, so aborting early only defers the inevitable and doubles the source egress. The crux holds.

3. Performance: non-issue

chainPosition is a linear scan (bootstrap.go:1171-1178). Worst case (topo strategy, linux) the chain is ~1.4M 20-byte hashes; two scans ≈ single-digit milliseconds per push, against pushes that each move up to ~512 MiB over a network. Hundreds of checkpoints → seconds total across an hours-long bootstrap. The loop already does comparable work per failure (subdivideCheckpoints rebuilds a full chain-index map, bootstrap.go:1408). If it ever registers, memoize one map[Hash]int per batch and both call sites get faster — don't do it preemptively.

4. Simplify now or land? Simplify now, on this branch

This isn't gold-plating; gold-plating polishes without changing the cost/risk profile. This deletes the exact state species where the real bug lived (relaxedRetried/relaxedBudget + idx++ resets at bootstrap.go:462-466, 801-803), fixes a second latent scoping violation of the same species (point 1b), removes a wasted upload and a double source fetch from the primary path, and fixes an edge livelock if you use >=. Decisive facts: the external contract is untouched — the sentinel, its classification rules, Params.AnnouncedTargetLimit, both capture sites (Execute at bootstrap.go:232, in-loop at 612) all survive verbatim — so the two open rollout items (consumer adoption of the sentinel, server sign-off on multi-GiB bodies) neither block nor are blocked by this. And the rollout gating means HEAD can't ship to production this instant anyway; that window is exactly when an internal-loop rewrite is cheapest. Honest cost: ~9 behavior tests (bootstrap_test.go:1820-2148) need assertion rework — mostly push counts 2→1 and margin expectations; fixtures and the fake target survive — and it's a genuine re-review while reviewers are still warm. The alternative, "land now, simplify later", is where internal rewrites of reviewed code go to die; if it doesn't happen on this branch it won't happen.

5. Simpler still? No — this is close to the floor

• One ceiling (budget = announced everywhere): wrong. The small budget earns its keep on divisible spans — frequent temp-ref advancement and ≤512 MiB waste per doomed push instead of ≤10 GiB. That rationale (Params comment, bootstrap.go:89-98) is untouched by the change; only its application to unsplittable spans was ever wrong.
• Drop budgetFromObservation: tempting (one bool), but it guards the real silent-proxy-cutoff case where announced and observed disagree; without it every delivery re-uploads into a wall. Keep it, hoisted.
• Drop the feature, sentinel only on parsed 413: re-creates the original bug — self-aborts at bottom-out become retry-forever with no server verdict ever sought.
• The up-front form is the minimal honest statement of the feature: "the abort budget for a span you cannot split is the server's number, not ours" — one condition at the aborter, one provenance flag, no retry machinery.

Verdict

No demonstrated correctness bug in the shipped logic — the up-front-ceiling rewrite is equivalent or strictly better than the retry design on every path I could construct or trace. But the commit should not land as-is: mutation testing shows it deleted the only coverage of the feature's central gate, and it left three stale comments describing the design it removed. Details, all demonstrated or precisely justified:

1. Confirmed sound (attack surfaces that held)

• Decide-up-front vs retry: atAnnounced (bootstrap.go:570-572) is computed after the pre-flight checkPackSizeAndSubdivide in the same iteration, and every continue recomputes it; the terminal check at :745-746 re-derives indivisibility from the same current/idx (the expanded list is only assigned inside the growth branch that continues, :704-729). The stale-resume re-plan (startIdx=0, current=ResumeHash, :407-441) is handled because isIndivisibleCheckpoint measures against current, not Checkpoints[idx-1] (:1329-1344). Subsumed branches never enter the loop.
• Loop safety with the latch gone: every continue (:534, :729) is gated on len(expanded) > len(remaining); growth is bounded by chain length; the success path always advances idx/current; recombine only runs after success. The announced-ceiling push is not a retry, so no latch is needed — failure paths either grow the list, return terminal, or return retryable. No no-progress cycle exists.
• Classification: with atAnnounced, observer.Aborted() can only be set by the strict bytesSent > ceiling aborter (pack_observer.go:110-125 — the aborter is consulted only when the read error is nil), so atAnnounced && abortedEarly ⟺ more than the announced limit's bytes of pack were actually read: terminal is justified regardless of what error the transport surfaces. A MaxPackBytes fetch-limit breach surfaces as a read error with Aborted()==false, and its message ("source pack exceeded max-pack-bytes limit", gitproto/readers.go:85) matches none of the terminal patterns → stays retryable. 408/504 stay retryable (tested). errors.Is traverses the %w: %w at :747-748 fine (tested). Best-effort swallowed ng → nil PushPack is a pre-existing hazard, unchanged here.
• >= and the guard at the boundaries: AnnouncedTargetLimit ≥ selfImposedBudget is an invariant whenever announced > 0 — announced only ratchets up from parsed limits (:232-233, :634-636), each parse simultaneously ratchets the budget to ≤ that value (:1281-1299), and the budget only falls. So >= matters exactly at equality, which is reachable (I proved it with a probe, below) and behaves correctly on HEAD.
• Amplification concern (traced, not a defect): when a pack > announced aborts and later gaps are still splittable, calibration from sentBytes≈announced (:665-680) makes the next pre-flight estimate ≥ 2×announced > TargetMaxPack, so subsequent rounds subdivide in pre-flight without pushing until bottom-out. Worst case ≈ 2 announced-sized uploads, same order as the old design.
• The scope move of budgetFromObservation (:375-380) fixes a real bug in the previously approved design: old code reset the flag per-branch (deleted lines at old :456-465) while selfImposedBudget persisted across branches, so branch 2 would treat branch 1's measured cutoff as "a figure we chose" and relax-retry past it.

2. Coverage holes — three mutants survive the FULL test suite

Verified by mutation (apply → go test ./... → restore):

• M1 (critical): delete isIndivisibleCheckpoint(batch, current, idx) from atAnnounced (:572) — entire suite stays green. Nothing pins the feature's central claim that only bottomed-out checkpoints escalate. This mutant pushes every checkpoint at the announced ceiling with no margin and no projection, silently destroying the waste-bounding that justifies TargetMaxPack — the deleted RelaxedBudgetDoesNotLeakToLaterCheckpoints test was the closest thing to coverage here and was removed without replacement. The suite needs a test with an announced limit set and a divisible checkpoint that must still abort at the small budget.
• M2: >= → > (:571) — entire suite green. The "pack sized in that last 5% aborts on every delivery forever" boundary the new comment defends is untested. It is real and pinnable — my probe (2-commit chain, TargetMaxPack: 1<<30, first push returns "http 413: body exceeded size limit 4200" so budget ratchets to exactly announced, body = 4108 bytes = 97.8% of 4200) passes on HEAD and fails under the mutant.
• M3: remove !budgetFromObservation (:570) — entire suite green, confirming the author's report. See below.

By contrast the mechanism itself is well pinned: disabling atAnnounced fails 5 tests; dropping (atAnnounced && abortedEarly) from :745 fails TestExecuteBatchedPermanentOnceTargetsOwnLimitIsExceeded; reintroducing the 95% margin at the ceiling fails TestExecuteBatchedNoSafetyMarginAtAnnouncedLimit.

3. The budgetFromObservation mystery — solved: the guard is live, the fixture was structurally incapable of reaching it

The guard is not dead code. It is assigned only at :685 inside the subdivide block, which requires all of: a batchable error, !abortedEarly, no parsed limit, and 0 < sentBytes < budget; and it is read only on a later loop iteration. This commit hard-coded bottomOutParams to a one-commit chain (bootstrap_test.go:1775) — and on a one-commit chain the guard is genuinely unreachable: any failure that sets it on the sole checkpoint either ends terminal immediately (an unparseable 413 still satisfies isTargetBodyLimitError) or returns retryably (408/504), and there is no next iteration to read the flag. Equally fatal: a fixture whose pusher returns the unparseable 413 without draining the pack leaves sentBytes=0, so nextSelfImposedBudget no-ops and the flag is never set at all. Either way, removing the guard changes nothing — hence the green mutant.

A biting fixture needs ≥ 2 commits: a divisible span to take the observation, then an indivisible one to consult it. This one passes on HEAD and fails when the guard is removed (I verified both):

4. Doc drift introduced by this commit

• bootstrap.go:548-553: a comment block still opens with "relaxedBudget, when set, raises the ceiling for THIS attempt only. It must not be written back into selfImposedBudget…" — relaxedBudget was deleted by this very commit; the paragraph describes the removed design and now sits fused onto the new comment.
• bootstrap.go:92-100 (Params.AnnouncedTargetLimit doc): "…the push is retried against this limit so the SERVER decides" — the retry no longer exists.
• bootstrap.go:109-111 (ErrCheckpointExceedsTargetLimit doc): "those are retried against the announced server limit first" — same staleness.

5. Minor behavior change worth a conscious sign-off

The log+notice at :575-582 now fires on every indivisible-checkpoint push once a limit is announced — including tiny packs nowhere near either number — whereas the old notice fired only after our budget had actually aborted one. After a deep subdivision episode this emits "cannot split further (1 commit) — pushing at the target's announced limit 10 GiB instead of 512 MiB" for kilobyte packs (bounded in practice by recombine regrowth, but per-push in uneven-gap states). Noise/UX only, no correctness impact.

Bottom line: land only after (a) adding a test that pins the indivisibility gate (M1 — the deleted leak test's replacement), (b) pinning the >= equality boundary (M2 fixture above), (c) restoring the budgetFromObservation guard's coverage with the ≥2-commit fixture above instead of concluding it dead, and (d) fixing the three stale comments, chiefly the dangling relaxedBudget block at :548-553.</result> <usage><subagent_tokens>167204</subagent_tokens><tool_uses>47</tool_uses><duration_ms>1041384</duration_ms></usage> </task-notification>

/loop — schedule a recurring or self-paced prompt

Parse the input below into [interval] <prompt…> and schedule it.

Parsing (in priority order)

1. Leading token: if the first whitespace-delimited token matches ^\d+[smhd]$ (e.g. 5m, 2h), that's the interval; the rest is the prompt.
2. Trailing "every" clause: otherwise, if the input ends with every <N><unit> or every <N> <unit-word> (e.g. every 20m, every 5 minutes, every 2 hours), extract that as the interval and strip it from the prompt. Only match when what follows "every" is a time expression — check every PR has no interval.
3. No interval: otherwise, the entire input is the prompt and you'll self-pace dynamically (see "Dynamic mode" below).

If the resulting prompt is empty, show usage /loop [interval] <prompt> and stop.

Examples:

• 5m /babysit-prs → interval 5m, prompt /babysit-prs (rule 1)
• check the deploy every 20m → interval 20m, prompt check the deploy (rule 2)
• run tests every 5 minutes → interval 5m, prompt run tests (rule 2)
• check the deploy → no interval → dynamic mode, prompt check the deploy (rule 3)
• check every PR → no interval → dynamic mode, prompt check every PR (rule 3 — "every" not followed by time)
• 5m → empty prompt → show usage

Offer cloud first

Before any scheduling step, check whether EITHER is true:

• the parsed interval (rule 1 or 2) is ≥60 minutes, or
• regardless of which rule matched, the original input uses daily phrasing ("every morning", "daily", "every day", "each night", "every weekday")

If either is true, call AskUserQuestion first:

• question: "This loop stops when you close this session. Set it up as a cloud schedule instead so it keeps running?"
• header: "Schedule"
• options: [{label: "Cloud schedule (recommended)", description: "Runs in Anthropic's cloud even after you close this session"}, {label: "This session only", description: "Runs in this terminal until you exit"}]

If they pick Cloud schedule: do NOT call CronCreate. Invoke the schedule skill directly via the Skill tool with args set to their original input verbatim (e.g. Skill({skill: "schedule", args: "every morning tell me a joke"})), then follow that skill's instructions to completion. Do NOT tell the user to run /schedule themselves. Then stop — do not continue to any section below (no CronCreate, no ScheduleWakeup, no "execute the prompt now"). If they pick This session only:

• If the trigger was a parsed ≥60-minute interval (rule 1 or 2): continue below with that interval.
• If the trigger was daily phrasing only (rule 3, no parsed interval): do NOT call CronCreate. Explain that a daily-cadence loop won't fire before this session closes, so there's nothing useful to schedule locally — suggest they either pick Cloud schedule, or re-run /loop with an explicit shorter interval (e.g. /loop 1h <prompt>) if they want a session loop. Then stop. If neither trigger condition was met: continue below.

Fixed-interval mode (rules 1 and 2)

Convert the interval to a cron expression:

If the interval doesn't cleanly divide its unit (e.g. 7m → */7 * * * * gives uneven gaps at :56→:00; 90m → 1.5h which cron can't express), pick the nearest clean interval and tell the user what you rounded to before scheduling.

Then:

1. Call CronCreate with: cron (the expression above), prompt (the parsed prompt verbatim), recurring: true.
2. Briefly confirm: what's scheduled, the cron expression, the human-readable cadence, that recurring tasks auto-expire after 7 days, and that the user can cancel sooner with CronDelete (include the job ID). Only if you did NOT show the cloud-offer AskUserQuestion above (i.e., neither trigger condition applied), end the confirmation with this exact line on its own, italicized: _Runs until you close this session · For durable cloud-based loops, use /schedule_. If the user already answered that question, omit this line.
3. Then immediately execute the parsed prompt now — don't wait for the first cron fire. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.

Dynamic mode (rule 3 — no interval)

The user wants you to self-pace. Decide what makes the next iteration worth running — a passage of time, or an observable event.

1. Run the parsed prompt now. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.
2. If the next run is gated on an event (CI finishing, a log line matching, a file changing, a PR comment) and no Monitor is already running for it: arm one now with persistent: true. Its events arrive as <task-notification> messages and wake this loop immediately — you do not wait for the ScheduleWakeup deadline. Arm once; on later iterations call TaskList first and skip this step if a monitor is already running.
3. Briefly confirm: that you're self-pacing, whether a Monitor is the primary wake signal, that you ran the task now, and what fallback delay you're about to pick. Write this as text before calling ScheduleWakeup — the turn ends as soon as that tool returns.
4. Then, as the last action of this turn, decide whether the loop continues. If the task needs another iteration, call ScheduleWakeup with:
   • delaySeconds: with a Monitor armed this is the fallback heartbeat — how long to wait if no event fires (lean 1200–1800s; idle ticks more frequent than the task needs are pure overhead). Without a Monitor this is the cadence — pick based on what you observed. Read the tool's own description for cache-aware delay guidance.
   • reason: one short sentence on why you picked that delay.
   • prompt: the full original /loop input verbatim, prefixed with /loop so the next firing re-enters this skill and continues the loop. For example, if the user typed /loop check the deploy, pass /loop check the deploy as the prompt.
   • noop: true if this tick changed nothing ("still waiting", "quiet hold"); false if it did something worth keeping. Consecutive noop: true ticks collapse in the terminal. If it doesn't need another iteration, stop instead (step 6) — re-arming is a per-turn choice, not a default.
5. If you were woken by a <task-notification> rather than this prompt: handle the event in the context of the loop task, then make the same decision. If the loop should continue, call ScheduleWakeup again with the same prompt and the same 1200–1800s delaySeconds from step 4 (the Monitor remains the wake signal; the new wakeup is only the fallback heartbeat). If the event means the work is finished, stop (step 6).
6. To stop the loop — the task is complete, further iterations can't make progress, or the user asked you to stop — call ScheduleWakeup with stop: true (no other fields) and TaskStop any Monitor you armed (use TaskList to find the task ID if it is no longer in context). Stopping is the loop's normal ending — the user can restart it anytime with /loop. Before you stop, send a one-line outcome via PushNotification — the user may be away and waiting to hear it's done. Skip this if you're stopping because the user just told you to; they're already here.

/loop — schedule a recurring or self-paced prompt

Parse the input below into [interval] <prompt…> and schedule it.

Parsing (in priority order)

1. Leading token: if the first whitespace-delimited token matches ^\d+[smhd]$ (e.g. 5m, 2h), that's the interval; the rest is the prompt.
2. Trailing "every" clause: otherwise, if the input ends with every <N><unit> or every <N> <unit-word> (e.g. every 20m, every 5 minutes, every 2 hours), extract that as the interval and strip it from the prompt. Only match when what follows "every" is a time expression — check every PR has no interval.
3. No interval: otherwise, the entire input is the prompt and you'll self-pace dynamically (see "Dynamic mode" below).

If the resulting prompt is empty, show usage /loop [interval] <prompt> and stop.

Examples:

• 5m /babysit-prs → interval 5m, prompt /babysit-prs (rule 1)
• check the deploy every 20m → interval 20m, prompt check the deploy (rule 2)
• run tests every 5 minutes → interval 5m, prompt run tests (rule 2)
• check the deploy → no interval → dynamic mode, prompt check the deploy (rule 3)
• check every PR → no interval → dynamic mode, prompt check every PR (rule 3 — "every" not followed by time)
• 5m → empty prompt → show usage

Offer cloud first

Before any scheduling step, check whether EITHER is true:

• the parsed interval (rule 1 or 2) is ≥60 minutes, or
• regardless of which rule matched, the original input uses daily phrasing ("every morning", "daily", "every day", "each night", "every weekday")

If either is true, call AskUserQuestion first:

• question: "This loop stops when you close this session. Set it up as a cloud schedule instead so it keeps running?"
• header: "Schedule"
• options: [{label: "Cloud schedule (recommended)", description: "Runs in Anthropic's cloud even after you close this session"}, {label: "This session only", description: "Runs in this terminal until you exit"}]

If they pick Cloud schedule: do NOT call CronCreate. Invoke the schedule skill directly via the Skill tool with args set to their original input verbatim (e.g. Skill({skill: "schedule", args: "every morning tell me a joke"})), then follow that skill's instructions to completion. Do NOT tell the user to run /schedule themselves. Then stop — do not continue to any section below (no CronCreate, no ScheduleWakeup, no "execute the prompt now"). If they pick This session only:

• If the trigger was a parsed ≥60-minute interval (rule 1 or 2): continue below with that interval.
• If the trigger was daily phrasing only (rule 3, no parsed interval): do NOT call CronCreate. Explain that a daily-cadence loop won't fire before this session closes, so there's nothing useful to schedule locally — suggest they either pick Cloud schedule, or re-run /loop with an explicit shorter interval (e.g. /loop 1h <prompt>) if they want a session loop. Then stop. If neither trigger condition was met: continue below.

Fixed-interval mode (rules 1 and 2)

Convert the interval to a cron expression:

If the interval doesn't cleanly divide its unit (e.g. 7m → */7 * * * * gives uneven gaps at :56→:00; 90m → 1.5h which cron can't express), pick the nearest clean interval and tell the user what you rounded to before scheduling.

Then:

1. Call CronCreate with: cron (the expression above), prompt (the parsed prompt verbatim), recurring: true.
2. Briefly confirm: what's scheduled, the cron expression, the human-readable cadence, that recurring tasks auto-expire after 7 days, and that the user can cancel sooner with CronDelete (include the job ID). Only if you did NOT show the cloud-offer AskUserQuestion above (i.e., neither trigger condition applied), end the confirmation with this exact line on its own, italicized: _Runs until you close this session · For durable cloud-based loops, use /schedule_. If the user already answered that question, omit this line.
3. Then immediately execute the parsed prompt now — don't wait for the first cron fire. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.

Dynamic mode (rule 3 — no interval)

The user wants you to self-pace. Decide what makes the next iteration worth running — a passage of time, or an observable event.

1. Run the parsed prompt now. If it's a slash command, invoke it via the Skill tool; otherwise act on it directly.
2. If the next run is gated on an event (CI finishing, a log line matching, a file changing, a PR comment) and no Monitor is already running for it: arm one now with persistent: true. Its events arrive as <task-notification> messages and wake this loop immediately — you do not wait for the ScheduleWakeup deadline. Arm once; on later iterations call TaskList first and skip this step if a monitor is already running.
3. Briefly confirm: that you're self-pacing, whether a Monitor is the primary wake signal, that you ran the task now, and what fallback delay you're about to pick. Write this as text before calling ScheduleWakeup — the turn ends as soon as that tool returns.
4. Then, as the last action of this turn, decide whether the loop continues. If the task needs another iteration, call ScheduleWakeup with:
   • delaySeconds: with a Monitor armed this is the fallback heartbeat — how long to wait if no event fires (lean 1200–1800s; idle ticks more frequent than the task needs are pure overhead). Without a Monitor this is the cadence — pick based on what you observed. Read the tool's own description for cache-aware delay guidance.
   • reason: one short sentence on why you picked that delay.
   • prompt: the full original /loop input verbatim, prefixed with /loop so the next firing re-enters this skill and continues the loop. For example, if the user typed /loop check the deploy, pass /loop check the deploy as the prompt.
   • noop: true if this tick changed nothing ("still waiting", "quiet hold"); false if it did something worth keeping. Consecutive noop: true ticks collapse in the terminal. If it doesn't need another iteration, stop instead (step 6) — re-arming is a per-turn choice, not a default.
5. If you were woken by a <task-notification> rather than this prompt: handle the event in the context of the loop task, then make the same decision. If the loop should continue, call ScheduleWakeup again with the same prompt and the same 1200–1800s delaySeconds from step 4 (the Monitor remains the wake signal; the new wakeup is only the fallback heartbeat). If the event means the work is finished, stop (step 6).
6. To stop the loop — the task is complete, further iterations can't make progress, or the user asked you to stop — call ScheduleWakeup with stop: true (no other fields) and TaskStop any Monitor you armed (use TaskList to find the task ID if it is no longer in context). Stopping is the loop's normal ending — the user can restart it anytime with /loop. Before you stop, send a one-line outcome via PushNotification — the user may be away and waiting to hear it's done. Skip this if you're stopping because the user just told you to; they're already here.

1. A 408/504 deadline silently disables the whole feature for the rest of the run. internal/strategy/bootstrap/bootstrap.go:792-797

subdivide includes deadlines (isBatchableTargetPushError = body-limit or 408/504). When a target drains the body and then times out — exactly the GitHub-408 behaviour documented at :1898 — abortedEarly is false and sentBytes > 0, so nextSelfImposedBudget ratchets the budget to those bytes and sets budgetFromObservation = true. That flag is never cleared except by a later parseable 413, and it gates atAnnounced, so escalation is dead for the remainder of the run.

That contradicts the PR's own principle: a deadline is treated as availability, not size for classification, but as measured size evidence for provenance. I confirmed it with a probe (3-commit chain, one-shot 413 announcing 1 MiB, then a drain-then-504 on the divisible span):

• as-is: 3 pushes, fails pack upload aborted early: projected to exceed target body limit
• with !budgetFromObservation mutated out of :674: converges, emitting cannot split further (1 commit) — pushing at the target's announced limit 1.00 MB instead of 4.01 KB

The narrow fix is to keep the ratchet (smaller packs genuinely do finish inside the window) but not the provenance claim:

budgetFromObservation = parsedLimit <= 0 && !isTargetPushDeadlineError(pushErr)

It heals on the next delivery, so it's not permanent — but it costs a full source re-fetch, on precisely the flaky multi-GiB targets this path serves.

1. The pre-flight subdivide has the same shape commit 3 just fixed. bootstrap.go:615-641

checkPackSizeAndSubdivide's callback calls subdivideCheckpoints, which splits every remaining gap — so an indivisible span at idx still grows the list when a later gap can split, and the loop continues to re-plan the identical checkpoint. It terminates (gaps are bounded at 1) and it's cheap (12-byte header read, then Close()), so it's not the multi-GiB waste of the post-failure path. But it's the same asymmetry, and it uses p.TargetMaxPack rather than the escalated ceiling. Worth at least a comment noting the difference is deliberate.

1. Two doc nits.

• errors.go:94 says the sentinel is returned by "Sync, Replicate and Bootstrap" — the root gitsync package has no Bootstrap method (only Probe/Plan/Sync/Replicate). It means unstable.Client.Bootstrap; worth saying so, since that comment is the mirror worker's contract.
• client.go:46 and :62 still read "Plan computes ref actions without pushing" / "Sync executes a sync between two remotes" with no mention that the result is now populated on error. That's a public API behaviour change whose entire purpose is to be read by callers — it should be documented. (Note validation and config errors still return a zero result, which is right, but makes the distinction worth stating.)
• bootstrap_test.go:2202-2206: drainAbort's doc comment is duplicated verbatim — a rebase artifact. <- review

To stop the loop — the task is complete, further iterations can't make progress, or the user asked you to stop — call ScheduleWakeup with stop: true (no other fields) and TaskStop any Monitor you armed (use TaskList to find the task ID if it is no longer in context). Stopping is the loop's normal ending — the user can restart it anytime with /loop. Before you stop, send a one-line outcome via PushNotification — the user may be away and waiting to hear it's done. Skip this if you're stopping because the user just told you to; they're already here.

hey i have another review

1. The pre-flight skip is unpinned. internal/strategy/bootstrap/bootstrap.go:626

Removing && !isIndivisibleCheckpoint(batch, current, idx) from the guard passes the entire suite. It's not a no-op — I probed it with a fetch counter on a 5-commit chain (gaps 1,1,1,2), TargetMaxPack: 81_920, makePackHeader(200) so the 200 × 750 estimate trips the pre-flight:

• with the guard: 9 fetches, 5 pushes
• without: 11 fetches, 5 pushes

So the behaviour is real and observable in two lines of fixture, it just has nothing holding it. Given this PR has mutation-verified every other claim it makes — and 3e55d75b exists solely because three mutants survived — this one stands out. The fixture above is enough; assert the fetch count.

1. packObjectCount is now always 0 on the escalated push. bootstrap.go:614, :648, :729

Skipping checkPackSizeAndSubdivide also skips the only thing that parses the pack header for a count, so for an indivisible span both log lines report object_count=0 and estimated_bytes=0 — on precisely the push this whole feature exists to make. total_objects_in_pack still works (the observer parses its own header), so the loss is confined to those two fields.

calibrationDenom := packObjectCount also goes to 0, which kills calibrateBytesPerObject — but that's inert in practice: with the new guard an indivisible span never takes the growth continue, so a failed push there always returns from executeBatched and there is no later iteration to consume the calibration. Log-only, but worth either fixing (read the header without the subdivide callback) or noting in the comment so the next reader doesn't chase the zeros.

1. Three small doc things.

• errors.go:96 — the edit didn't reflow: that line is 107 chars in a block that otherwise wraps at ~79.
• bootstrap.go:1581/1582 — no blank line, so nextBudgetProvenance's doc comment now begins with the 14 orphaned lines of observedSubdivisionFactor's prose. The fusion is pre-existing on main (observedSubdivisionFactor's doc has always sat above nextSelfImposedBudget, with the function itself defined ~70 lines lower), but the new function inherits it, so a brand-new symbol is documented by a paragraph about pack subdivision multipliers. One blank line fixes the new half; moving the block down to :1639 fixes the original.
• client.go:47 / :71 — "Counts describe what was attempted, not what landed" reads as a warning against over-reading, but on the only path that populates a result on error, bootstrapWithInputs never carries bResult.Pushed, so Counts.Applied is 0. It understates rather than overstates. Worth one word, since that comment is the mirror worker's contract. The rest of the field names check out — Execution.OperationMode, TransferMode (from RelayMode), Reason (from RelayReason), Batch, Refs all exist and map as described.

I found two integration/documentation issues. The core bootstrap sizing and classification logic looks sound.

1. [P2] Failure-route telemetry still stops at the SDK boundary. The PR now returns execution metadata alongside errors (client.go), but the companion worker discards result whenever lastErr != nil; route fields are logged only on success (worker sync path, error return at 513). Failed batched bootstraps therefore still won’t expose TransferMode/Reason in production logs—the stated ENT-2054 observability outcome. Thread the partial result into failure span/log reporting.

2. [P3] The new stable API contract is absent from the changelog. ErrCheckpointExceedsTargetLimit is a new caller-facing sentinel (errors.go), and error-return behavior changed, but Unreleased only documents #117. Downstream embedders need this contract in release notes.

Reviewed PR #118 at head fcf98d1a, base 48724707.

• Focused bootstrap and syncer tests passed locally.
• License, lint, test, govulncheck, and Bugbot checks are green.
• PR is mergeable but currently BLOCKED with REVIEW_REQUIRED.
• The required worker companion is not yet pushed and still pins old SHA b06c763d; it must be repointed and shipped with this change.
• Multi-GiB target behavior remains simulation-tested, not live-target verified.
