swamp vault read-secret terminates its plain output with a newline even when stdout is not a TTY. Piped or redirected output is therefore <value>\n, not the secret bytes — anything that consumes the stream as-is stores a corrupted secret. Expected: when stdout is not a TTY, output is exactly the stored bytes.

Repro (swamp 20260820.072114.0, fresh repo, local_encryption vault):

$ printf 'abc' | swamp vault put v probe     # store exactly 3 bytes
$ swamp vault read-secret v probe --yes | xxd
00000000: 6162 630a                                abc.

Expected: 3 bytes (abc). Actual: 4 bytes (abc\n).

Scope: vault put strips one trailing newline from stdin, so swamp-to-swamp round-trips self-correct, and --json output is unaffected. The corruption hits external consumers of the piped output — seeding another secret store (e.g. systemd-creds encrypt), writing a key file, or any pipeline that treats the stream as exact bytes.

Ask: omit the newline when stdout is not a TTY, or add a --raw flag.

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

Only documented non-interactive auth puts the password in argv; the safe SWAMP_API_KEY path is undocumented

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)

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

docs: update vault audit trail reference for write operation support

docs: document --dashboard flag for swamp serve

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

Relative path for custom agent skills setup doesn't provision skills

swamp serve daemon enable: add --dashboard flag

CLI writes runtime state (lastStalenessWarning) into tracked .swamp.yaml, dirtying a committed config file

extension install serializes files[] in readdir order, producing machine-dependent reorder diffs in upstream_extensions.json

Workflow YAML rewritten in place: block-scalar description truncated, file left unparseable, and validate still reports PASSED

workflow validate does not resolve modelType on factory-pattern steps — a non-existent extension validates clean

vault.get() arguments are verbatim, so a per-target secret cannot be expressed in workflow YAML

Cancellation/--timeout skips remaining steps including `completed`/`always` branches; --timeout waits for the in-flight subprocess

Remote "write-bearing" classification is inferred from data-plane writes, not declared; external side effects can be re-executed on worker disconnect (docs say the opposite)

Audit timeline is not populated by swamp CLI commands unless the AI-tool hook fires (manual says recording is automatic)

manual_approval suspends the run while parallel sibling jobs are mid-flight; in-flight steps are torn down and left `running`

`workflow resume --from` does nothing for forEach steps whose template name contains `${{ }}`

Step-level dependsOn on a forEach step never evaluates true (except `always`)

rum/site-info: lookup GETs a non-existent endpoint, always 405

vault read-secret appends a newline to piped output

wss:// direct to serve's own TLS listener still fails on 20260817 — client ALPN lands on h2, WS-over-h2 unimplemented (follow-up to #1363)

serve: vault audit repository not wired up — audit trail always empty

Support Jira webhooks with X-Hub-Signature HMAC-SHA256 verification

Add typed read-only remote ref lookup to @swamp/git

pullChanged skips same-size updated files — size-only change detection ignores the index sha256

A run's terminal status reaches the shared datastore only when a later run happens to push it

workflow cancel --all on the serve host shuts down the serve process

Readability of tables in documentation

repo init/upgrade --tool kiro references .kiro/skills/ but installs skills to ~/.kiro/skills/

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

data.findBySpec() returns only the first in-run record, not all of them, so an .all() assert silently checks one element

repo upgrade --tool kiro reports wrong changedFiles paths

Suppress boot-time "pulled extension(s) have missing source files" WRN when invoked command is `swamp extension install`

s3-datastore: a stale machine's sync pushes its old 'latest' pointer over the newer remote one, and the rollback is permanent

`search` → `list` aliases are hand-rolled Command clones, not aliases: 10 of 11 have drifted from their parent's option set

Make official Docker image OCI-compliant

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

data prune still misclassifies live records as orphans on 20260820 (after #1396) — serve-minted token/grant records, and report data of every live workflow

vault put prompts for the secret before validating the vault name exists

workflow validate: false 'Missing required inputs' for CEL-templated globalArgs (${{ inputs.* }})

Add SWAMP_CLI_OUTPUT env var to control default output mode (plaintext/tui/json)

@swamp/git fetch: support local path as remote

Dispatched steps over 15 minutes cannot write results: dispatch credentials expire and never refresh

Concurrent pushes to one namespace fail with HTTP 409 ConditionalRequestConflict — the conditional PUT is never retried

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

--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

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

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

"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"

access token mint writes to user vault, not serve's _token-secrets control plane in HA mode

Generic OTLP endpoint appends signal path after query or fragment
