Provider shutdown handed the manager a remaining budget, but flush_all ran first with no deadline and blocked on each session's flush lock. An async upload still in flight held that lock, so shutdown waited the full HTTP timeout past its declared budget. flush_all and the queue drain now take the deadline, skip a session whose lock or budget is gone, and log one warning with the count of messages that stayed unsynced.
With recallSync on, prefetch popped only the auth notice and returned without writing the injection log. A session whose init failed for a missing user peer never told the model that memory was off, and the audit file stayed empty for every turn. The recall sync branch now pops the peer notice the way the async branch does and records each turn as injected or recall-sync-empty.
Parametrize the sessionStart, injection-log, dashboard user_id, unresolved-peer
and deferred-save tests that differed only in their inputs. Share the blocking
remote in the concurrent flush tests. Fold _as_flag onto a word table. Cut the
added docstrings to the what and the one non-obvious why.
recall_sync.py spawned honcho-recall-sync without owner=, so shutdown's
join_plugin_threads((self, manager), ...) never saw it. The worker now
registers under the provider like the other provider threads.
`_flush_session` discarded the observation flags when it rebuilt an evicted SDK session, and the
cached path returned none, so recall fell back to the config snapshot. Both paths now return and
store the flags. A deferred `save()` on a session the cap evicted puts it back in the cache, or
flushes it inline when a newer object owns the key. `save()` and `stop_async_writer()` share the
writer lock, and the writer drains its queue after the join, so a put that raced shutdown is
written. The trim after a flush runs under the cache lock. The shutdown join takes the remaining
budget instead of a fixed ten seconds.
The injection audit file is created owner-only, and `logging: "false"` reads as off. The desktop
passes `<provider>:<user id>` so a basic-auth alice and an OIDC alice are two peers. When a
gateway platform supplies no user id, the peer notice and tool error no longer recommend
peerName, which would merge every user of that gateway onto one peer. README documents
`injection.sessionStart`, `logging`, and what a dashboard login does to peer resolution.
a desktop or cli session with no peerName in honcho.json and no gateway
user id landed on a peer derived from the session key: user-default-<dir>
for per-directory sessions, user-<channel>-<chat> for keyed ones. every
directory got its own phantom peer, so the operator's turns and memory
never reached their real peer and the injected representation went stale
(#93326).
_resolve_user_peer_id now raises HonchoPeerUnresolvedError instead of
deriving a name. a peer is either the declared peerName or an identity
the transport supplied. the provider records the failure, tells the model
once that memory is off and which key to set, returns the same detail
from tool calls, and stops retrying init because a missing config key
does not heal mid-session. the memory-file migration gate loses its
"no owner and no runtime identity" branch: that cohort no longer has a
session to migrate into. whitespace-only peerName is treated as unset
rather than sanitized to "--".
provider shutdown joined the dialectic, sync and memwrite threads for 5s
each and then the async writer, but the session-init thread,
honcho-base-first and honcho-context-prefetch were never joined. any of
them still blocked in httpx when the interpreter finalized aborted the
process with SIGABRT 134 (#37632, #60616, #33485). the 5s join was also
shorter than the 30s http timeout a blocked call can hold (#33485).
spawn_context_thread now registers each thread under its owner (the
provider or the manager) in a weak registry, and shutdown joins every live
thread of both owners inside one deadline: at least 5s, or the configured
http timeout when longer. the manager refuses new prefetch threads once
shutdown began and flushes a late save() inline instead of respawning the
writer. threads that outlive the budget are named in a warning.
the sdk client exposes close() on its http pool. one client is shared by
every manager with the same identity in a gateway process, so a per-agent
shutdown cannot close it; close_honcho_clients() closes all pools and is
registered with atexit when the first client is built, the pattern the
hindsight and mem0 plugins use. follows #69070, #33701, #7627.
the idle sweep from #71463 left three growth paths open. _peers_cache had no
bound at all, _session_observation (from #98941) grew one entry per session
id and kept orphans when an init failed after add_peers, and a burst of
distinct sessions inside one ttl window was not bounded. the sweep also
evicted sessions whose messages had not reached honcho yet, which in
"session" write mode drops the only copy, and _flush_session re-inserted an
evicted session into the cache with no observation flags, so recall for it
routed from the config snapshot instead of its server config.
_cache and _sessions_cache now cap at 128 entries and _peers_cache at 512,
evicting least recently used first (dict order, refreshed on every hit).
a session with unsynced messages is never evicted by the sweep or the cap.
_configure_session_peers returns the synced flags and get_or_create stores
them under _cache_lock next to the cache entry, so the observation dict can
hold no id the cache does not; eviction drops both. recall reads go through
_cached_session, which stamps updated_at, so a read-only session survives
the idle sweep. follows #71461, #71463, #98936.
_flush_session read the unsynced messages, posted them, and only then set
_synced. in a short-lived run the async writer draining save()'s queue and
the exit-time flush_all() both saw the same batch unsynced, so every turn
of a one-shot run landed in honcho twice (#92458).
each HonchoSession now carries an RLock that _flush_session holds around
the whole select, send, mark sequence. the second flusher enters after the
first marked the batch and sends nothing; different sessions still flush
in parallel. the lock lives on the session object instead of a manager
dict keyed by session id (#86094, #92787): it needs no eviction, and two
flushers of one message list can never hold different locks. tests
adapted from #86094 and #92787.
The four observation booleans on HonchoSessionManager were manager-wide
mutable state initialized from per-session server configs: every session
setup overwrote them, so the last session to initialize retuned recall
routing for all other sessions the manager serves. Store the server-synced
flags under each session's own id instead; the manager-level fields stay
as the config snapshot and sessions that never synced fall back to them.
injection.sessionStart: unset renders every component in table order, an
empty list renders nothing, a pinned list renders only those names in table
order (not config order), a host block pin beats root, a non-list value is
treated as unset, and initialize() reads the pin.
logging: off by default, the logging key or HONCHO_LOGGING turns it on, a
host block can turn it back off, HONCHO_INJECTION_LOG overrides the path,
each record carries reason/turn/session_key/bytes/payload, an unwritable
path never raises, and a tools-mode prefetch logs its reason. the record
holds the user's representation verbatim, which is why the default stays off.
the two session-context tests that asserted exact context() kwargs now expect
tokens= as well (adopted from #92964). config_schema declares the logging
switch so hermes memory setup shows it.
Salvage of #70951 (Willkons / Alice-Willk-bot). Two of three
session.context() sites never forwarded the configured cap, so Honcho
always returned honcho_chat_summary_long.
Adds the missing get_session_context tokens= regression the sweeper
asked for on that PR.
force_refresh_token gated the adopt-from-disk paths behind the failure cooldown.
After one of our exchanges failed transiently, a 401 within the next 30s returned
None even when a sibling process had already rotated and written a valid grant,
so the operation raised HonchoAuthError with a good token sitting on disk.
Adopting is a disk read, not an exchange; the cooldown exists to stop replaying a
single-use refresh token, so the two adopt checks now run before the gates.
_write_config parsed honcho.json twice under the lock and only wrapped the first
read into ConfigWriteRefused; _refuse_unparseable now returns the parsed dict and
the branches use it. The getattr/isinstance duck-typing collapses to one guard.
cli._read_config reuses oauth's tolerant reader (BOM-tolerant, like the strict
reader the write side uses) instead of its own utf-8 copy.
The unreadable/corrupt variants asserted the same two invariants (writers raise
and leave bytes untouched; rotation fails before the exchange) in five tests;
they are two parametrized tests now. The two lock-spy tests only asserted that
the implementation called the lock helper; the threaded save_config test is the
behavioral guard for the same property.
_write_config applied a command's edits relative to the snapshot the read took, but never moved that snapshot after a successful write. A second write on the same object therefore compared A -> B -> A against A, saw no change, and left disk at B. After a write the snapshot and path now follow the caller's dict, so the next write applies only the edits made since.
_read_config() falls back to ~/.honcho/config.json or the default profile when honcho.json does not exist, so cfg.path never matched the write path and _write_config() wrote the whole dict. That overwrote a refresh rotation a serve child had written onto the honcho.json the setup login created moments earlier. When the local file exists at write time, the seed snapshot is now overlaid with the local file and only the command's edits are applied onto it.
install_grant writes the login grant to disk before the wizard's later prompts. _apply_grant_to_host wrote it only into the live cfg, so _write_config saw the grant as an edit and copied it over whatever a serve child rotated onto disk meanwhile. The snapshot now takes the grant too, so the final save leaves the newer on-disk grant alone.
Near-duplicate tests become one parametrized test each: the 401 adopt
cases, the invalid_grant race, the setup apikey answers, the clone and
enable credential checks, and the plain-dict writes. _point_cli_at
replaces the per-class monkeypatch helpers in test_cli. The removed-key
check folds into the merge test, and the missing-file bootstrap check
into the file-lock test; the command-level refusal test already drives
_write_config through ConfigWriteRefused, so the unit test for it goes.
The spy helpers in the install_grant lock test and the reauth bearer
test lose their duplicated closures. Every behavior the removed tests
asserted still has an assertion.
clone and enable accepted HONCHO_API_KEY from the environment as proof the
block could authenticate and wrote enabled: true. the variable can be absent
from the next process, leaving an enabled block with nothing behind it, which
is the cohort the previous commit set out to remove.
_resolve_api_key takes env=False at both write sites, so a block is enabled
only when honcho.json itself holds a key, an oauth grant, or a self-hosted
baseUrl. status and setup keep the environment fallback for display.
every hermes honcho command read honcho.json, changed a field, and wrote the
whole dict back with no lock. a token refresh in another process that landed
between the read and the write was overwritten with the old access and
refresh tokens, and the next refresh replayed a rotated single-use token.
_write_config now holds the same cross-process file lock the refresh path
holds, re-reads disk under it, and applies only the keys the command changed
since its _read_config(). untouched keys keep their on-disk value, so a
rotation survives; a credential the command set on purpose still wins. a
write with no prior read keeps today's whole-file behavior.
a named profile cloned from a default profile that signed in with oauth
got a host block with enabled: true and nothing to authenticate with.
hosts.hermes holds the grant, its apiKey is not inherited (#66125), and
copying the oauth block would make two blocks replay one single-use
refresh token. 'hermes honcho enable' on a fresh profile wrote the same
shape. status then showed the profile as enabled while every honcho
call ran without memory and the plugin quietly stayed inactive.
clone_honcho_for_profile and cmd_enable now resolve a credential for the
target block (its own apiKey, the root apiKey, HONCHO_API_KEY, or a base
url) before writing enabled: true. _resolve_api_key takes the block to
check so both share one definition of "can authenticate".
cohorts:
clone from an oauth default block, no root key: block written without
enabled; the client's auto-enable rule turns it on once a credential
appears (setup apikey writes the root key, or a per-profile login)
clone from a default block with a host-level static key only: same
clone with a root apiKey, an env key, or a base url: enabled as before
enable on an empty or fresh block with no credential: refused, one
message names the profile's setup command and the hosts.<name> key,
nothing is written
legacy blocks already on disk as enabled with no credential: nothing
rewrites them; the plugin already treats them as unusable and stays
inactive; enable now prints the same message instead of "already
enabled"
env-only key: counted as a credential at write time, as the client
does at run time; if the variable later disappears the client still
refuses to initialize the block
after the token endpoint revoked a grant (invalid_grant), running
'hermes honcho setup', choosing apikey and pasting a valid key changed
nothing. the wizard wrote the key to the root apiKey only. hosts.<name>
still held the dead access token under apiKey and the grant under oauth,
and the host block wins the lookup, so status kept reporting the revoked
grant and every call kept failing (#97990).
the apikey branch now drops the host's oauth block and writes the chosen
key onto the host block as well as the root. a dead access token is no
longer shown as the current key, so a blank answer with no other key
aborts instead of keeping the grant. a static host key without a grant
is kept as before.
a login finishing while a refresh was rotating the same honcho.json ran
its read-modify-write unlocked. the two writers could interleave: the
login read the file, the refresh persisted a rotated token, the login
wrote its own copy back and the rotated token was gone.
install_grant now holds _refresh_lock and _config_refresh_lock(path)
around the strict read, the config merge and the persist, the same way
force_refresh_token does. the token response is parsed before the locks
so a malformed grant never holds them.
a truncated or hand-edited honcho.json reads as {} on the tolerant read
path. the next write then replaced the file with only the current host
block: an oauth refresh, a login, or any 'hermes honcho' command that
saves a setting wiped every other host and the root keys.
_read_config_strict now raises on a parse error the same way it raises
on a read error, and logs one sentence naming the file. _rotate_and_persist
treats that as a refresh failure and enters the cooldown without spending
the refresh token. install_grant raises into the setup flow. in cli.py
every write goes through _write_config, which runs the same check first
and raises ConfigWriteRefused; the honcho router, the setup wizard and the
profile sync print the sentence instead of a traceback. the wizard checks
before asking its questions. read paths keep the {} fallback.
follows #95860, which added the strict reader for unreadable files and
kept a .corrupt copy on a parse error. leaving the original file in place
keeps the same bytes without a second copy of the tokens on disk.
_persist_credential promises "leaving all else intact", but it seeded
its write from _read_config, which returns {} on ANY read failure, and
_atomic_write_config replaces the whole file via os.replace — which
needs only a writable parent, so a present-but-unreadable honcho.json
did not stop the overwrite. One OSError (EACCES after a root-owned
write, EIO, a stalled mount) during an automatic token refresh or a
fresh login therefore replaced the store with a single-host file,
destroying every other host's credentials and honcho.json's root
config. No user action is required to trigger the refresh path.
Same defect class as #75206 (P1, fixed for the core auth store in
Add _read_config_strict for the write paths: a missing file still
bootstraps as {}; an unreadable file raises with the store untouched;
genuine corruption still degrades but preserves a .corrupt copy first,
since a truncated store usually holds the other hosts' tokens verbatim.
_rotate_and_persist now takes its strict read BEFORE the exchange —
rotation is single-use, so an exchange whose result cannot be persisted
loses the grant — and threads the dict through to _persist_credential,
which also closes the re-read race between the locked read and the
persist. install_grant seeds its root-merge from the strict reader for
the same reason. Read paths keep their fail-open contract untouched;
both readers now use utf-8-sig so a BOM'd store is not misclassified
as corruption (the wipe vector needing no filesystem fault at all).
Adds TestPersistReadFailure: six tests, four of which fail against the
previous source; the rotate-ordering test additionally pins that no
exchange is attempted against an unreadable store.
reading the live client's api_key inside _force_reauth races the in-place
rotation: a sibling waiter's apply_token_to_client (or the proactive
refresh entered via the honcho property) can swap the bearer before the
read, so force_refresh_token receives the already-rotated token, disk
matches it, and the adopt branch never fires — reproducing the very
force-refresh burst this PR removes.
_authed_call now snapshots the bearer before invoking the operation and
passes that exact token through to force_refresh_token.
desktop spawns multiple serve processes that share one rotating honcho
refresh token. force_refresh_token treated every 401 as "rotate now" even
when a sibling had already persisted a new grant, which can replay a
single-use refresh token and revoke the whole grant.
re-read honcho.json under the existing file lock and adopt if the token
that 401'd is no longer on disk. on invalid_grant, re-read once more
before marking the grant dead.
Six of eight memory providers spawned plain threading.Thread for prefetch/sync/
writer work. A plain thread starts with an EMPTY contextvars.Context, so under
multiplex profiles the worker resolved the DEFAULT profile's HERMES_HOME (and
fails closed on scoped secrets). honcho and hindsight had each noticed and
written their own copy_context() wrapper; core had a third in memory_manager.
One canonical pair now lives on the ABC module every provider already imports:
agent/memory_provider.py::ctx_bound / spawn_context_thread. memory_manager,
honcho, hindsight, mem0, retaindb, byterover, supermemory and openviking all use
it; the honcho and hindsight wrappers and memory_manager._ctx_bound are deleted.
Five "json.loads(path.read_text()) or {}" readers (mem0._read_mem0_json,
honcho client/oauth/cli _read_config, hindsight save_config/_load_config) fold
into utils.read_json_or_empty, the read half of every read-merge-atomic_json_write
sidecar store.
holographic.save_config was the only config.yaml writer in the tree that
bypassed hermes_cli.config.save_config: raw open("w") + yaml.dump with no config
lock, no managed-mode refusal, no atomic replace, and a swallowed exception. It
now calls save_config(..., merge_existing=True). Behavior change: a managed
install refuses the write (previously silently rewrote config.yaml); other
sections are deep-merged instead of round-tripped through a raw dump.
openviking._hermes_home_path guarded an impossible ImportError of
hermes_constants (the module already imports agent.*) with a ~/.hermes fallback
that is wrong on Windows and under profile overrides; it is replaced by
get_hermes_home() directly.
Tests: tests/plugins/memory/test_provider_threads_inherit_profile.py drives each
provider's real spawn path with a fake backend and asserts the thread sees the
spawner's HERMES_HOME override (sabotage: retaindb back on threading.Thread ->
red). tests/plugins/memory/test_holographic_save_config.py pins merge-with-
existing-sections and managed-mode refusal (sabotage: raw yaml.dump -> red).
plugins/platforms/a2a/security.py::redact_outbound shipped text to a REMOTE peer
through 8 private regexes (sk-, sk-ant-, ghp_ only, xox[bap] only, AKIA, JWT,
Bearer, email) and never called redact_sensitive_text, so every prefix added to
agent/redact.py (hf_, glpat-, xapp-, npm_, Telegram bot tokens, private keys,
DB URLs, env assignments, auth headers, plugin-registered patterns) was absent
on the A2A path. gateway/run.py::_GATEWAY_SECRET_PATTERNS and
agent/monitoring/redaction.py::_TOKEN_RE/_BEARER_RE were two more parallel
"fallback" lists to maintain.
Now agent/redact.py::redact_for_egress is the one egress scrub:
redact_sensitive_text(force=True) + a bearer sweep for prefix-less opaque
tokens, fail-closed ("[redaction-unavailable]"). Gateway user-facing text,
monitoring export and A2A outbound call it; A2A keeps only its e-mail pass.
Behavior changes: a2a egress now masks the full canonical set; the gateway
chat path returns the fail-closed sentinel instead of a raw string when the
redactor raises; honcho plugin registers hch-at-/hch-rt- with
register_redaction_patterns (masked on every surface; mask shape is the
shared head/tail form instead of "hch-at-[redacted]"); proxy_cli token
display uses mask_secret (4 visible prefix chars instead of 12).
Invariant test: redact_outbound masks a synthesized token for every
registered prefix pattern (fails when reverted to the private list).
Keep the isolation contracts (bot never on the human peer, bot turn never in the
human session, writes refused mid bot-turn, one join per author, signature busts
the cache) and drop the alias/prefix/sanitize enumerations. 795 -> 454 lines.
sync_turn reads a2a_sessions from the config bound when the provider was built. A cached gateway provider kept the old value after honcho.json flipped it, because the signature that busts that cache did not carry the flag.
_joined_author_peers kept an entry for every honcho session the manager ever wrote to. It now holds at most _SESSION_CACHE_MAX_SIZE sessions and drops the oldest past that, so a forgotten session's authors rejoin on their next write. A failed join no longer leaves an empty entry behind.
The join read the manager-wide user_observe_me and user_observe_others directly. It now asks _join_observation_flags(honcho_session_id), which returns the same values today. #103889 stores the effective flags per session and replaces the body of that method.
_generated_runtime_peer_id takes a reserved set, and the bot path passes the session's human peer ids: each runtime id and the peer _resolve_user_peer_id returns for the key. bot:coder with a runtime human coder and no runtimePeerPrefix now gets the digest suffix. _explicit_user_peer_ids keeps its meaning for prefixed runtime users.
Two senders named coder on different connections get different peers and different a2a sessions, and a userPeerAliases entry keyed by the full connection-qualified id wins.
identity_signature now carries cfg.workspace_id. The gateway folds these values into its agent cache key, and a workspace change in honcho.json reused a cached agent that was still bound to the old workspace.
_a2a_session_key now names the session <session>:a2a:<aiPeer>:<sender id>-<digest>. Two profiles that share a workspace and a session key wrote one sender's DMs into one Honcho session. The recipient peer comes from the same aiPeer derivation the session builder uses, moved into session_peers.assistant_peer_id_for so the two cannot drift.
_peer_id_for_runtime_id now looks up userPeerAliases by the full bot id and otherwise passes everything after bot: through _generated_runtime_peer_id. A digest suffix is added when sanitizing changed the id or the result equals peerName or an alias target, so bot:eri never resolves to the operator's peer and bot:a.b stays apart from bot:a-b. The docstring and README no longer claim a cloned profile's aiPeer defaults to the profile name.
The plugin spelled the `a2a:` prefix itself. `agent.turn_author.a2a_key` is the shared name
for a bot author's turns, so the session key now derives from it and every reader that files
bot turns apart agrees on the prefix. The resulting key is unchanged.
A gateway platform marks a bot sender with its raw user id and a bot flag, never a `bot:` id.
`resolve_author_peer_id` treated that author as a human, so `pinUserPeer` collapsed a bot onto
`peerName` and an unresolved peer opened the a2a session under the human's peer. The resolver now
takes `is_bot` and gives every bot its own peer. `sync_turn` skips the turn when no peer resolves
or when the peer equals this agent's `aiPeer`.
The a2a session key carries an eight-character digest of the author id, so two ids that sanitize
alike stay in separate sessions. During a bot-authored turn `honcho_conclude` and `honcho_profile`
refuse writes and the built-in memory mirror is skipped, because conclusions and cards describe
the human. The README paragraph on bot DMs now matches the code.
with pinUserPeer on, resolve_author_peer_id returned None for every author,
so a bot dm's words were written under the human's pinned peer inside the
a2a session. the pin exists to unify one person's platform accounts. a bot
is not one of them.
bot: authors now resolve to their peer before the pin check, so a pinned
operator still gets bot speech attributed to the bot.
A DM relayed from another Hermes profile ran as a turn in the recipient's
Bot Chat session. sync_turn wrote the bot's words and the recipient's reply
into that session, and before per-author writes they landed under the
human's peer. The human's representation absorbed conversations the human
never had.
The turn context now marks such turns with scope a2a:<bot id>.
sync_turn routes a bot-authored turn into a separate Honcho session keyed
<session>:a2a:<sanitized bot id>, created with the sender bot as its user
peer, and never writes it into the human's session. The key is deterministic
so every turn from the same bot reaches the same session, and it stays
inside Honcho's 100 character session id limit. Recall still reads the
human's session only.
a2aSessions (host block, then root, default true) turns the routing on.
With it off, bot-authored turns are skipped. A bot turn that names no
author id is skipped as well, because nothing can key its session. Human
turns are unchanged.
get_or_create takes a user_peer_id override so the a2a session's roster is
the bot and the assistant, not the runtime human.
The gateway agent cache read honcho.json itself through a honcho-named
block in gateway/run.py and gateway/run_agent_cache.py. Every other memory
provider had no way to bust the cache when its identity mapping changed.
HonchoMemoryProvider.identity_signature() now returns the same values under
provider-neutral keys: user_identity, agent_identity, pin_user_identity,
runtime_identity_prefix, user_identity_aliases, session_prefixing. The
gateway files them under memory.<key> through the MemoryProvider hook. The
hook reads config only, memoizes on the file's mtime and size, and returns
an empty dict when the file cannot be read.
The honcho-specific extractor, its memo and its key tuple are gone from the
gateway. The pinPeerName cache-busting test now asserts on
memory.pin_user_identity.
The bot-mode dispatcher names another profile as bot:<profile>. The
resolver treated that like a human runtime id, so a configured
runtimePeerPrefix produced peers like telegram_bot:coder and a profile
that already owns an AI peer in the same workspace got a second one.
A bot:<profile> author now resolves in this order: a userPeerAliases entry
for the full bot id, else the sanitized profile name. A cloned profile's
aiPeer defaults to the profile name, so a same-workspace sender lands on
its existing AI peer. Prefixes never apply to bot ids. pinUserPeer still
collapses bot authors onto the pinned peer, the same as every other author.
sync_turn only knew the author through the on_turn_start stash. The memory
manager now passes turn_author and scope with the turn, and a caller
that skips on_turn_start left the stash empty or stale.
sync_turn takes both keywords and reads the author from turn_author first.
The stash stays as the fallback for callers that never pass it.
resolve_author_peer_id compared the author against the primary runtime id
only. A transport that names the participant by the alt id (Telegram
username instead of UID) got a second peer for the same person. Either
runtime id now counts as the session's own participant.
The manager resolved one user peer in `get_or_create` and froze it onto the
session, then `_flush_session` chose between it and the assistant peer by
role. Every user turn in a shared session landed on that one peer, so the
first person to message the agent collected everyone else's facts — and a
Honcho conclusion, once derived, is not self-correcting.
`resolve_author_peer_id` maps the turn's author onto its own peer using the
alias-then-prefix order `_resolve_user_peer_id` already applies, so an
aliased account reaches the same peer whichever turn it wrote. `sync_turn`
resolves it before starting the write thread, so a following turn cannot
retag a queued write. `_flush_session` then writes each user message under
that peer.
A shared session's roster is open — people and other agents arrive after
the session exists — so `_author_peer_for_session` joins a peer when it
first writes instead of enumerating participants at init. Joins are
remembered per session, and a failed join still writes under the right
peer, losing only the observe config.
Three cases return None and keep the session's own peer: no author named,
the author IS the session's peer, and `pinPeerName` set — that flag is an
explicit request to unify identities, so it still collapses authors in a
shared chat.
An unnamed author stays unattributed rather than defaulting to the owner.
That preserves today's behavior for the transports that send no author, so
those turns still reach the session peer; #83500 owner-gated the memory-file
migration for the same reason.
Display names never become peer IDs — they are attacker-influenceable on
any platform where participants set their own name.
