The branch and push methods on @swamp/git fail with a data-naming validation error when the git branch name contains / (e.g. issue-7988/default-content-guard).

The git operation itself succeeds, but swamp rejects the data output because the branch name is used directly as the data name, which triggers the path-traversal guard:

Data name must not contain '..', '/', '\\', or null bytes (path traversal)

Steps to Reproduce

swamp model @"@swamp/git" method run branch <model> \
  --input name=feature/my-branch --input create=true --input startPoint=main

swamp model @"@swamp/git" method run push <model> \
  --input branch=feature/my-branch --input remote=origin

Both commands complete the git operation but exit with code 1 due to the data name validation error.

Expected Behavior

The data name should sanitize / characters (e.g. replace with - or _) so that branch names with slashes — a very common git convention — work without errors.

Actual Behavior

Exit code 1 with the path-traversal validation error. The git operation succeeds silently but the method is reported as failed.

Thanks @dkliban for reporting this! The fix has been merged and a release is on its way. We appreciate your contribution to swamp.

serve: triggerSource not persisted to workflow run summary

dataOutputOverrides not applied during remote execution — ephemeral resources GC'd before override takes effect

extension rm also deletes the lockfile entry, and install on an empty lockfile is a silent success — rm/install is not a round trip

vault: audit trail should record put, delete, and annotate operations

ExtensionWorkflowRepository scans manifest.yaml as a workflow, emitting 'Unknown key manifestVersion' warning

--max-run-duration only applies to detached runs, not attached runs

Cancel endpoint reports status: cancelled for runs it did not actually cancel

@swamp/git: no way to amend a commit, but push can --force

Installation with new account creation times out

pre-flight checks run on orchestrator, not on worker — breaks remote execution with filesystem-dependent checks

Docs: update cancel endpoint response statuses in REST API reference and workflows page

docs: document --remote-only flag for swamp serve

Swamp serve daemon doesn't run with --hot-reload

serve: include workflowName in HealthSnapshotSchedule

Retyping a model instance strands catalog rows no command can reclaim — prune matches on model_id, delete resolves the current type (follow-up to #1009)

knowledge-base retrieve persists query output into the state resource, with lifetime infinite and the query text in the instance name

Method-name collision between a base model type and an extending extension silently drops the whole extension file — no error, doctor reports pass

Skip 50MB monolithic index rewrite on v2 shard-first path

Share single AwsS3Client instance across lock, sync, and verifier

Double shard assembly per command lifecycle (pull + push both read all shards)

pullChanged never records commitSeq for shard-first (v2) index

localHasAllRemoteEntries() permanently blocks sidecar update on partial caches

serve: workflow.history.get cannot find CLI-created runs or look up by run ID

"TRIAL ENDED" modal shown to team plan user when toggling extension visibility

Concurrent suspended workflow runs can't be disambiguated from 'approvals'; fresh runs should supersede matching-input suspended runs

I _think_ I might like a guard in the trigger yaml

swamp cmds don't realise the user is sshed into the system

serve dashboard: add cluster.instances and serve.config endpoints

CEL expressions have timestamp/duration but no current-time value, so no guard can express "older than N"

No way to store code-review results — verdicts, findings, and cost are not persisted for any repo

Redaction regex boundary bug: label_base64 secrets with an unrecognized label pass through unredacted (e.g. swamp_ API keys)

User token page (/u/<user>) shows only "swamp_..." for every API key, making leaked-key identification impossible

upstream_state treats sparse-fetch branches as having no upstream

Add native support for the Pi coding harness

Cloud Build create supplies project instead of required projectId path parameter

workflows: support labels/target/platform at job and workflow level

swamp access grant create never registers the grant — a --deny created this way silently fails open

Support credentials in datastore config (vault-resolvable)

swamp serve OOMs on repos with 2000+ model definitions

Serve telemetry attribution for collectives

Extension workflows: no way to override trigger configuration

Add a list/discover method to the generated @swamp/aws types — no way to enumerate resources in a region

Document @vault= prefix for webhook secrets in serve.yaml

swamp access grant create installs an unrelated extension from the registry

docs: document SWAMP_API_KEY headless OAuth bootstrap for swamp serve

workflow-succeeded selects the globally-latest run, so siblings block each other under parallel use

swamp serve: webhook secrets should support @vault= resolution

Misleading collective_not_trusted auto-resolve error when a local source extension transiently fails to index during workflow validate

datastore setup: symlinks not counted in bytesCopied, causing misleading '(0B)' output

vault.get() CEL error embeds raw newline when wrapped by model resolver, producing broken output

Feature: user-configurable redaction rules (.swamp/redaction.yaml)

Fatal JavaScript out of memory: Ineffective mark-compacts near heap limit

Sync every signup to Attio, and backfill the existing population (#809 follow-up)

@swamp/issue-lifecycle probes /api/health, which swamp-club stopped serving when the Fresh scaffold stubs were removed

Lab lifecycle POST rejects any payload string that starts with a dollar sign, not just operator keys

Push down the two cheap leaderboard scans: ghost-gate dictionary and eventCounts owner filter

$identify events are never consumed — anonymous web history never binds to the account

Finish the swamp_* attribute set on Attio users, and settle the two unprefixed ones (#809 follow-up)
