It is one +verbatim string in the basic prefab's own Concat order, with original labels and +line breaks. It also appears in the standard host-side logs. The Journal download +remains your observations and submitted actions. The final action is always your +input, not the model's suggested behavior. +Sable-9, Thorn and the GM keep their existing composition and policies. + +The default remains `--player-prefab minimal`, the previous lightweight +configuration with no LLM-based player context processing. In `--role gm`, this +option still selects Ilyra's prefab, but Ilyra uses its normal LLM acting policy +and the human controls the GM. Python callers can use +`build_cast(..., player_prefab='basic')` or `play(..., player_prefab='basic')`. + +The library injection is reusable independently of this example or transport: + +```python +from concordia.components.agent.human_act_component import HumanActComponent +from concordia.prefabs.entity import basic + +player = basic.Entity(params={'name': 'Ilyra Venn', 'goal': 'Repair the loom.'}).build( + model=model, + memory_bank=memory_bank, + act_component_factory=lambda order: HumanActComponent(read, component_order=order), +) +``` + +The factory receives the exact order calculated inside the prefab (including +the goal placement); no ordering list is duplicated in the example. Both basic +and minimal also accept a prebuilt `act_component`, but the two options are +mutually exclusive. Omitting both leaves the library's default `ConcatActComponent` +(including its ordering and choice/name-prefix options) unchanged. No parallel +copy or subclass of the basic prefab is maintained. + +## Phone access on an existing tailnet + +The web server binds **only to 127.0.0.1**. Use Tailscale Serve, not Funnel. Inspect +current configuration first and add only the new path; never reset other routes. +For a host named `your-host.your-tailnet.ts.net`: + +```sh +tailscale serve status --json +# Include these flags on the web command above: +# --allowed-host your-host.your-tailnet.ts.net --root-path /astral-canticle-play +tailscale serve --bg --set-path /astral-canticle-play http://127.0.0.1:8767/astral-canticle-play +``` + +Open `https://your-host.your-tailnet.ts.net/astral-canticle-play/` on your phone. +The trailing slash matters for relative asset URLs. The proxy target preserves the mount +prefix; the adapter also accepts prefix-stripping proxies. Same-origin JSON +POSTs, host validation and a restrictive CSP protect the browser boundary. This +is a **single trusted tailnet controller**, not an authorization system: anyone +with access to this route shares control. Do not expose it publicly. Existing +`/astral-canticle`, `/astral-canticle-data`, and `/game-design-forum` are separate +log/forum routes and need not be changed. + +## Human game master and terminal input + +Launch with `--role gm` to control the GM instead. All three player entities then +use their default LLM policies. You provide observations, pick actors, create +valid next-action specs, resolve attempts and decide termination. GM decisions +are never silently filled in by model-based context components. Choice buttons +use exact option values; the action-spec builder creates validated JSON. Both +roles see only the controlled entity's complete pre-act context; unrelated NPC or +GM component outputs are never added to it. This is a developer-oriented secondary UX; +the default player mode is the polished single-human experience. + +The same adventure also works without **any web dependencies**: + +```sh +.venv/bin/python -m concordia.examples.astral_canticle.terminal --role player +# Use --role gm for terminal GM control. +``` + +A minimal transport implementation is simply a callable: + +```python +from concordia.components.agent.human_act_component import HumanActComponent + +def read(request): + print(request.context) # Already ordered and labeled; do not reassemble the map. + if request.error: + print(request.error) + return input(request.action_spec.call_to_action + '> ') + +act_component = HumanActComponent(read) +# Install in EntityAgentWithLogging, or pass to minimal.Entity.build( +# model=model, memory_bank=memory_bank, act_component=act_component). +``` + +`concordia.typing.human_input.HumanInputRequest` contains the entity name, unique +request ID, immutable context map, preassembled `context` string, action spec and +retry feedback. Core has no knowledge of HTTP, browsers, threads or Tailscale. Independent readers can be +wired to additional human entities in a future application; this example keeps +one inbox per controller and deliberately implements no multiplayer routing. + +Only `{name}` in a call-to-action is interpolated, without corrupting literal +JSON braces. Free prose must be nonempty, numbers finite, choices exact, and a +GM's `NEXT_ACTION_SPEC` must decode to a valid player `ActionSpec`. Skip actions +return without requesting input. Cancellation/EOF is raised, never converted to +an invented action. Context lifecycle and standard logging remain unchanged. +LLM-based context components can still use a model when someone composes a +human entity with them; the default minimal selection uses only non-LLM human +context components, while basic preserves its LLM-backed perceptions. + +### Context ordering contract + +`HumanActComponent(reader, component_order=None)` uses the context mapping's +iteration order. An explicit sequence uses that order first, then appends +unspecified keys **alphabetically**, exactly as the existing Concat implementation +does. Empty strings are skipped; all other labels, spaces and line breaks remain +intact. Explicitly named absent keys raise `KeyError` when acting; duplicate keys +raise `ValueError` at construction. `get_context_concat_order()` returns the +snapshotted order, and state saves/restores it with Concat's existing conventions +(including its empty-order-to-None state normalization). The reader is not saved. + +Both policies call the same standard `concat.concat_contexts` helper; transports +render `request.context` verbatim rather than adding dictionary headings. The +player and GM UI both show it expanded in the scrolling page (not a cramped +composer panel), and terminal input prints the very same string. Context only +comes from the entity attached to this HumanActComponent. Showing the human's +own perception outputs does not expose another entity's private components. + +## Composition and verification + +The example reuses `minimal.Entity` / `basic.Entity`, `EntityAgentWithLogging`, observation/memory +components, `SwitchAct`, `NextActingInFixedOrder`, `FixedActionSpec`, +`Sequential`, `SimulationLog` and its standard `to_html()` renderer. A constant small +embedding is sufficient because this composition retrieves chronological +observations, not semantic neighbors. The GM sees the recent event history and +setting; we do not duplicate an engine, event resolver, clock or logging system. +Unlike the heavier time-and-place prefab, the lean GM tracks the Canticle Clock +in narrative context rather than generating separate clock/location LLM calls. + +```sh +.venv/bin/python -m pip install pytest pytest-xdist pyink isort +.venv/bin/python -m pip install -r concordia/examples/astral_canticle/requirements-test.txt +.venv/bin/python -m playwright install chromium +.venv/bin/python -m pytest -n 0 \ + concordia/components/agent/human_act_component_test.py \ + concordia/components/agent/context_order_test.py \ + concordia/environment/engines/sequential_test.py \ + concordia/prefabs/entity/basic_test.py \ + concordia/prefabs/entity/prefabs_test.py \ + concordia/examples/astral_canticle +``` + +Unit and browser tests use mock models or transport requests, never a live model. +They cover exact Concat/Human context/order parity, full basic perception outputs +visible verbatim in player/GM mobile views, basic/default component parity and +perception lifecycle, CLI selection, player/GM contracts, normal NPC policies, a complete standard-engine +round, stale/duplicate actions, cross-origin rejection, reconnects, draft recovery, +mobile layout, safe text rendering, and GM action-spec controls.

The simultaneous engine +already uses standard concurrency utilities and a GM observation/log lock. +The asynchronous engine validates `ReactiveMeasurements` and has different +pause/capture behavior. Do not implement another scheduling loop or treat +async completion order as simultaneous choice. + +## Runnable simultaneous resource council + +This is a separate, deliberately small analogue of cooperative resource +governance, **not the full Bellwether game**. Nell, Ivo and Sam each hold one +unit. Each independently chooses: + +- `contribute`: explicitly authorize and execute donation of *their own* unit + once the complete batch has arrived; +- `keep`: retain their unit. + +Unlike Bellwether's request/accept/transfer/work stages, this contract makes the +choice itself authorization for immediate execution. There are no promises, +watch costs, hidden material effects, majority seizure or claimed social welfare +metrics. A member's choice cannot supply another member's consent. + +From the contribution checkout: + +```sh +python -m pip install -e '.[dev]' +python -m concordia.examples.bellwether.council --output runs/council-fixture +``` + +The command uses standard `NoLanguageModel`, fixed choice ordering and zero +fixture embeddings. Every fixture actor picks the first choice, `contribute`. +Expect one completed simultaneous round, three actions, Community3 / members0, +and the original3 units conserved. Outputs: + +- `trace.json` and `trace.html`: standard SimulationLog exports; +- `outcome.json`: fixture label, complete flag, round count, decisions and + inventory for this declared case. + +The output proves software wiring and accounting, not cooperation among people. +One round is a bound, not a method for hiding incomplete results: check +`complete`, participant set and recorded inventory. + +## Composition, reuse and failure semantics + +`council.configuration()` returns a fresh standard Config and CouncilLedger. +It composes existing minimal actors, SwitchAct, NextActingAllEntities, +FixedActionSpec, MakeObservation/ObservationQueue and Inventory.apply. +CouncilLedger implements only the *scenario-specific* complete-batch rule. +The executable uses generic.Simulation with standard Simultaneous; no custom +engine or server is introduced. + +All member/spec names are known before execution. Inputs are exact validated +choices. The engine may omit a failed actor task from its batch; the ledger +therefore rejects incomplete, duplicate, unknown or malformed batches **before** +any inventory mutation. A single Inventory.apply validates all contribution +deltas. Batch arrival/line ordering does not change the resulting balances. +Re-resolving the identical complete batch cannot spend resources twice. +An invalid batch raises an error; no silent partial round or inferred vote is +treated as success. + +The fixed initial public observation contains rules, not other actors' current +choices. Actions are exposed to the GM only for collective resolution; this +example has no public browser view or per-user authentication of its own. +Raw developer traces can contain actor context. Do not publish them unchanged +if adding private information. + +## Plug in real policies or human input + +Use the same returned Config with a configured standard language model for +actors, retaining the explicit moderator components. Reuse the local timeout, +call-limit and profiling wrappers in `run.py`; a live sample is not a guarantee +of the all-contribute fixture outcome.

Both can be pending concurrently; **do not share one +blocking terminal prompt or assume the sequential browser's one-active-turn +projection supports this council unchanged**. The main multiplayer transport +remains built for Bellwether's ordered night. HumanAct's normal choice validation +remains in force; other actors keep their standard policies. + +## Making another analogous example + +1. State the timing semantics: sealed simultaneous intentions, sequential + observable moves, or truly asynchronous interactions. +2. Use standard prefabs and choose the standard engine matching those semantics. +3. Define what a choice authorizes, what is only speech, and what evidence + material transitions need. Keep rules, beliefs, enforcement and compliance + distinct. +4. Test missing/failed actor behavior, partial effects, conservation, privacy, + scheduling boundaries and termination before interpretation. +5. Record engine/model/config/revision and full private traces, then produce + intentionally sanitized research outputs. Seeds do not make hosted models + deterministic, nor do traces create empirical warrant. + +For example, the same council contract can teach independent mutual-aid +contributions or a cooperative reserve decision.

This command uses the existing Ollama adapter; +requests have a 90-second HTTP timeout, 256 output-token cap, and a 256-call +wrapper limit. The standard per-run profiler records timings and token +**estimates**, not measured billing. Exhausted/invalid output cannot grant +consent. Model failures end the run with the retained journal and developer +error; there is no hidden fixture fallback. Use Ctrl-C to close the owned +listeners. A new process starts a new night; checkpoint continuation is not +implemented by this example. + +The standard `basic` prefab is an alternative via `--resident-prefab basic`. +Its perception components make additional model calls. Four residents share the +selected architecture but have separate standard memory, observations, goals, +accounts and affiliations. Developers can configure their individual instance +params in `game_prefab.configuration`. The human uses HumanAct, not an LLM. +The GM uses independently composed SwitchAct policies and explicit scenario +rules, not the resident decision logic. + +## Optional local memory embeddings + +The compatibility default is an eight-dimensional **constant placeholder**. +It permits fixture plumbing but does not provide meaningful semantic retrieval, +including when live residents use `basic`. To use real local embeddings, install +an embedding-capable model separately in your existing Ollama service: + +```sh +ollama pull all-minilm +python -m concordia.examples.bellwether.run --mode live --model llama3.2:3b --resident-prefab basic --embedding-model all-minilm --output runs/bellwether-embeddings +``` + +The optional adapter feeds the standard `generic.Simulation` callable-embedder +interface and existing `AssociativeMemoryBank`; it does not replace retrieval. +It uses only `127.0.0.1:11434`, does not inherit proxy settings, and makes no +automatic model downloads. Capability checks happen before memory transmission. +Requests use a 30-second HTTP timeout and reject truncation. Vectors must be +finite, nonzero, and dimension-consistent; they are normalized because the +standard bank scores with a dot product. A failed request is surfaced, never +silently changed to a constant embedding. + +Developer state and `outcome.json` identify constant, provided-callable, or +local-model embeddings. The existing private profiler records request counts, +failures, timings, and dimensions—not memory text or vectors. This metadata is +not added to player views. Model dimensions, vocabulary and latency vary; +`all-minilm` has a short input context and can reject long memories. Choose an +appropriate installed model for your text rather than silently truncating it. +This is not a quality benchmark or a guarantee that a chosen actor architecture +will use associative retrieval. Do not mix a saved bank's vectors with a different +model or placeholder; checkpoint compatibility/continuation is not implemented. + +Trusted Python callers can instead pass `embedder=callable` to `Game` or +`SharedGame`, using their existing embedding library. No web configuration can +load arbitrary Python callables. Slice mode keeps its original fixture default. + +## Playing + +Select suggestions to fill the input, or enter a command and your own words. +There is deliberately a small, conservative physical-action vocabulary. +Unrecognized or ambiguous physical instructions ask for clarification **before** +waking the pending human turn. The parser is not a general natural-language +physical simulator. + +| Intent | Example | +|---|---| +| Public conversation / open-ended proposal | `tell everyone: Can we find a plan that protects boats and families?` | +| Address one resident publicly | `tell Mara: What worries you about the cooperative?` | +| Private conversation | `message Nell: I want to hear your account.` | +| Ask for material consent | `ask Nell for fuel and part` | +| Ask for labor consent | `ask Ivo to repair` | +| Collect the agreed resources | `transfer reserve and part` | +| Ask Ivo to carry out accepted work | `order repair` | +| Allocate this watch's supply | `allocate all` or `allocate shelter and cold store` | +| Make your own promise | `promise shelter` | +| Withdraw your latest unfulfilled promise | `withdraw my promise` | +| Advance without agreement | `wait` | + +`propose to everyone: …` preserves creative prose for resident discussion. +It cannot invent a new action mechanic or bypass resource/consent checks. +Residents respond in their own voices. An explicit structured `accept` records +only that resident's requested commitment; spoken claims alone are not consent. +Residents may decline, counter, or revoke their own unfulfilled commitment. +The next proposal can take their response into account; acceptance is not forced. + +Nell's material commitment releases two fuel and the spare part. Collecting them +is a separate action. Ivo's labor commitment is distinct from performing the +repair: he may still refuse the work order. Repair requires accepted Ivo labor, +the delivered part, and actual performance **before Before Dawn**. A late repair +does not rewrite already-resolved services. General item trades and arbitrary +new engineering procedures are intentionally not silently adjudicated as valid. + +## Material rules and two strategies + +The generator has **6 fuel**, Nell has **2 reserve**, and there is **1 spare +part**. The beacon, shelter and cold store demand one fuel in each of three +watches: baseline demand 9. A completed repair removes only the final beacon +demand. The standard Inventory tracks Generator, Nell, Ivo and Used accounts; +fuel and the part never appear from narration. Requested allocation order +determines supply priority if there is insufficient fuel. Consumption occurs +at watch boundaries, after that choice's bounded resident responses. + +Two useful plans, not guaranteed live social outcomes: + +1. **Negotiate full service:** in Dusk ask Nell for fuel/part, collect them, + ask Ivo to repair, then wait. In High Tide order the accepted repair; + leave all facilities allocated and use the other choices for promises or + discussion. Keep all allocated Before Dawn. With Nell's acceptance and + Ivo's accepted **and performed** work, 8 fuel supplies all 9 facility-watches. +2. **Prioritize shelter and livelihoods:** allocate shelter and cold store in + each watch. This consumes 6 fuel, leaves Nell's reserve untouched, but + records three missed beacon watches and the associated harbor consequences. + +The fixture demonstrates both. Live residents can defeat either social plan +through refusal or changed commitments. Waiting always allows progression to +dawn even without agreement. Dawn shows actual service, fuel, repair, +honored/broken/revoked/unfulfilled commitments, and each resident's response. +Missed beacon service delays safe arrivals; missed shelter service removes +heating; missed cold-store service risks stock. These are explicit fictional +scenario consequences, not predicted casualties or economic estimates. + +At High Tide a **disputed** account of the previous storm is delivered to its +configured recipients. It does not establish objective truth or rewrite +memory. Use `--dispute-file account.json`: + +```json +{"text": "Mara says the cooperative did not help; Nell disputes that account.", "recipients": ["Coordinator", "Mara", "Nell"]} +``` + +The object is validated before building. Institutions distinguish charter, +membership, enforcement and who knows about the disputed account. The default +delegates reserve custody to Nell and labor consent to Ivo; membership does not +grant someone else's consent. Interaction records describe changing positions +without imposing scalar trust or a single psychological theory. + +## One service, three clients + +The existing `OperationService`, `SimulationServer` and attached +`concordia-session` CLI remain the authority. The player GUI uses the same +`human.respond` handler available on its listener. Developer GUI/CLI edits use +the same designated `component.edit` as [the original slice](README.md). + +Additional operations: + +| Operation | Audience | Meaning | +|---|---|---| +| `game.begin` | player | Explicit one-time start | +| `game.preview` | player/developer | Parse an attempt without effects | +| `run.resume` | developer | Resume the existing paused worker; never replay | + +```sh +concordia-session --url http://127.0.0.1:8786 discover +concordia-session --url http://127.0.0.1:8786 state +concordia-session --url http://127.0.0.1:8786 watch +concordia-session --url http://127.0.0.1:8787 state +``` + +A mutation uses the discovered arguments plus the current references/revision +and an exact retry key, as in README.md. Retry the identical request after a +lost response; stale edits fail atomically. Selecting Pause does **not** permit +editing while a worker or human request is still active. The designated edit is +safe before Run or after the worker has joined. Initial configuration remains +distinct from runtime. This is not a general mid-run transaction or checkpoint +interface. + +Player HTML/JSON/SSE contain only public facts, the coordinator's delivered +observations and messages they participated in. The standard observation queue +separately delivers private events to the relevant residents. Developer +checkpoints and traces stay on the trusted editor listener; they are never +hidden in player HTML. Both listeners bind to loopback. This example changes no +routes, account configuration, lobbies or access controls. + +## Verification and limits + +```sh +python -m pip install pytest playwright +python -m playwright install chromium +python -m pytest -n 0 concordia/examples/bellwether concordia/contrib/language_models/ollama/ollama_model_test.py +``` + +Rule tests exercise conservation, both strategies, refusal, commitment +revocation, late/missing-part repairs, malformed resident output, atomic +clarification, recipient privacy and fresh ownership. Chromium tests use real +components, HTTP, SSE and attached CLI with a synthetic pending input and +explicitly forbid simulation execution. + +Separate browser walkthroughs executed both complete fixture strategies and a +local live night through standard Simulation/Sequential: 12 human choices each, +four dawn responses, reload/reconnect recovery, matching CLI snapshots and no +JavaScript errors. The live run used 12 successful local llama3.2:3b calls +(about 2.9–6.0 seconds each); Nell declined and no reserve transfer or repair +was fabricated. Live timing is one machine/run observation, not a guarantee. +Automated browser submission timing is not a human play-duration measurement. + +Logs are standard `simulation.json` and `log.html`; `outcome.json` adds +the explicit night result, per-step timings, model profile and backend label. +The 15–25 minute human experience is a target, **not yet measured**. The full +Bellwether editor/showcase A–H, isolated checkpoint branches, experiments, +authoring assets/undo/breakpoints, every editor-family parity and fresh +environment export remain subsequent work. No original workflow acceptance +baseline is upgraded merely because this bounded game now reaches dawn. + +### Standard basic extensions + +The optional basic residents retain their standard perception chain and normal +ConcatAct policy. `basic.Entity` now supports `extra_components` and +`extra_components_index` using the **same extracted assembly helper** as +`minimal.Entity`; basic defaults and minimal insertion semantics are unchanged. +This supplies each resident’s account, affiliations, and scenario instructions +without copying the basic prefab or silently ignoring configuration. Default +and injected-policy regressions accompany both advertised configurations. + + +## Two human roles + +See [MULTIPLAYER.md](MULTIPLAYER.md) for optional host-approved Coordinator/Nell +play, private role journals, Android controls, and the HTTPS boundary. Omit +`--multiplayer` for the unchanged single-human game. + +## Optional voice + +[Local voice controls](VOICE.md) add opt-in spoken observations and editable +dictation on supported devices, retaining full text fallback. Android on-device +recognition is not assumed. + +## Contributor recipes + +The [researcher starter kit](RESEARCHER.md) maps the architecture and provides +tested mutual-aid, resource-governance and institutional-dispute variants, +with explicit assumptions and extension boundaries. + + +## First-play guidance and free interpretation + +The role banner states whether this is single-player (human Coordinator plus +four computer-controlled residents) or a shared night (human Coordinator and +Nell plus three computer-controlled residents). Fixture residents are labelled +scripted, not live-model results. **How to play your role** explains your own +controls; spectators see public information and no action controls. + +The Coordinator can type an attempt and choose **Check interpretation · free**. +This calls the same existing `game.preview` parser available to the attached +CLI. It does not send an action, reserve resources, spend a choice or predict +consent/success. Requests, accepted commitments, transfers, performed repairs, +allocations and service promises stay distinct. A message to everyone is public, +even if typed with the `message` prefix. Literal speech stays literal text. + +Only **Send action** submits an attempt. Checking first is optional. Editing the +draft or changing turn/role invalidates old interpretations; a delayed reply +cannot overwrite the interpretation of a newer draft. Connection loss cancels +the pending preview, and saved drafts reappear only after the service identifies +the session/role on reconnect. Nell keeps the structured accept/decline/speak UI, +not the Coordinator's action parser. + +Browser regression checks cover the standard service/HTTP parser, free-query +state equality, malformed/literal messages, stale delivery, reconnect and actual +host-approved Nell/spectator pages with simulation execution prohibited. They do +not establish physical Android usability or replace full played-night evidence. + +## Reading service status without relying on color + +Each map location now says **Not resolved yet**, or names the last resolved +watch and whether service was **Maintained** or **Unserved**. The generator yard +shows its current fuel stock. The glow and dashed border are supplementary; +keyboard and screen-reader names contain the same status in words. Map inspection +still has no turn cost. + +**Service across the watches** shows a native table with watch row headers and +facility column headers. **Not resolved** means there is no recorded outcome +for that watch; it does not predict success or failure. Requested allocations and +promises are not delivered service. The table and map reuse only the existing +public service records, so spectators receive the same accounting without role +journals or private conversation data. + +Browser checks use one watch resolved through the existing scenario component +as a deterministic fixture (no Simulation.play/entity.act/model invocation). +They verify the initial/served/unserved distinction, keyboard-only inspection +without API mutations, 360px portrait, 800px landscape, forced colors and enlarged +text. These are software/accessibility checks, not physical-phone or human +usability validation. + + +## Initial teaching presets + +Use `--recipe mutual-aid`, `resource-governance`, or `institutional-dispute` +with `--mode fixture` or `live` to play a trusted teaching variation through +the same server and engine. The default is `bellwether`. See +[RESEARCHER.md](RESEARCHER.md#select-the-same-initial-case-in-the-browser) for +commands, exact initial-condition changes and interpretation limits. A preset +is selected only at launch, not applied to a running night. Existing game +processes are never replaced by this option. + + +## Reading and composing during live updates + +Repeated snapshots no longer recreate unchanged resident buttons, action +suggestions or resident decision options. Keyboard focus stays on the same +native control. The journal appends new visible events without replacing its +unchanged prefix, and unchanged context text is retained, so copying a passage +does not lose the selection merely because another update arrives. Draft text +and its caret remain yours until an intentional edit or submission. + +A changed location filter, completed input session or role boundary still +updates which controls and content are available. Revocation clears the retained +journal immediately; rejoining as a spectator never restores the previous +role's private text or action controls. Retention is local presentation state, +not a durable checkpoint or a guarantee that an active operation can be cancelled. + +Real Chromium checks cover narrow portrait/landscape, native keyboard focus, +selection through repeated/appended journal snapshots, draft/caret retention, +changed filter/completion and host revocation/rejoin. These tests republish +scoped snapshots and component fixtures, without running a simulation or model. +They are not physical-device or screen-reader usability studies. + +## Optional model-side image drafts + +[Local visual notes](VISUAL-NOTES.md) provide an explicit image-to-text CLI with +an installed vision-capable model. On your own turn, the optional image-note +review control reads its JSON locally, lets you edit it, and explicitly append +the text to your existing draft before manual Send. It does not upload the note, +attach images to shared actor context, or automatically submit an action. + + +### Why a resolved service was supplied + +In **Service across the watches**, select **Served** or **Unserved** for a +resolved facility. This free inspection displays the boundary's recorded +request priority, available fuel and fuel spent, or the completed-repair rule. +An omitted request is distinguished from a requested facility that lacked fuel. +Requests are considered in their submitted order; later allocations or stock +changes do not rewrite the prior explanation. + +These are explanations of Bellwether's material accounting rules, not of a +resident's motives or the legitimacy of an institution. They do not establish a +scientific causal conclusion. Readable public accounts include the same notes; +public JSON adds an optional allowlisted service resolution object and demand. +Older service records without these fields say that boundary details were not +recorded, rather than inferring a reason from later stocks. + + +### Setup context in a public account + +Saved public JSON, readable HTML and the public SVG now carry the trusted +recipe's declared setup: recipe name, standard actor prefab/engine, human role +names and initial fuel assumptions. The mutual-aid recipe declares two units +used before play and six initially available; cumulative Used must not be +confused with consumption during play. + +This optional public projection is **not a complete run configuration**. +Private component edits, initial memories, prompts, model settings, browser +identities and session references are excluded. A recipe label neither captures +all interventions nor guarantees deterministic replay or empirical validity. +World-only/older records without setup provenance remain explicitly unknown; +the exporter never infers setup from later stock or narrative. + + +### Player names and watch labels + +The player UI calls the Coordinator **Coordinator Alice** and labels the first +watch **Watch 1 · Early evening**, so a time-of-night badge is not mistaken for +a resident. High Tide and Before Dawn retain their existing names. + +These are display aliases only. Authenticated role IDs, join request values, +draft recovery keys and entity names remain Coordinator; the first recorded +watch remains Dusk. Raw dialogue, the human component's assembled context, +public account records and API/CLI values are not rewritten. The role guide +explains this mapping. Existing hosted chapters are not reset by this change. + +### Sending and uncertain connections + +The action area distinguishes **Sending** (confirmation pending), **Action +received** (delivery confirmed, not a successful outcome), rejection, and an +unconfirmed network reply. A lost reply does not mean that nothing was sent: +check the journal before sending again. No automatic retry or fabricated model +progress is shown. If the same prompt is still open and the draft is unchanged, +a manual Send reuses the existing server idempotency key. + +You can edit your draft while an acknowledgment is pending. A late success +clears only the unchanged draft that initiated it; re-entering identical text +counts as a new edit. Revocation or a changed browser role clears the old +submission's presentation, and its delayed success or failure cannot modify +the new role's draft. Submission feedback is page-local; reload obtains the +current scoped server state, while existing draft recovery remains in use. + +Chromium regressions cover delayed success, pre-send network loss, a lost +successful reply, validation rejection, same-key manual retry, same-text edits, +role revocation/rejoin, and narrow portrait/landscape. They use synthetic human +input and real server/SSE delivery with simulated client network delays. +Simulation.play and resident-model calls are blocked; standard Inventory +construction still uses its NoLanguageModel helper. These are not measured +phone-network reliability or physical-device usability results. + +### Live basic residents and action-only structured output + +The live launcher uses two views of the same local model. The ordinary model +serves standard basic self-perception, situation-perception and +person-by-situation questions as prose. Only the final standard ConcatAct policy +uses Ollama's JSON-schema output for the existing decision/speech contract. +The schema permits every existing decision (including refusal and revocation); +it does not determine consent, truth or material consequences. The game still +validates actions and enforces the same resource and commitment rules. + +Resident configuration selects the standard prefix_entity_name option as false +so JSON is not prefilled with a resident name. Minimal now honors that option +with its previous true default unchanged; basic already supports it. Human +readers take precedence over the model-backed policy. The action-model binding +is runtime-only, not a serialized object or an imported module from a project. + +For already installed local models, select --mode live --resident-prefab basic +--model llama3.2:3b --embedding-model all-minilm in the normal source-checkout +launch command. Use unused private ports and a distinct output directory. +Sequential remains the engine. Each HTTP request is limited to 90 seconds and +256 generated tokens; the existing call-limit wrappers reserve 192 context +calls and 64 action calls, at most 256 total. The shared standard profiler counts +both paths. No provider/model download or silent embedding fallback is added. + +Basic makes additional component-generation requests compared with minimal; +semantic embedding makes additional local requests. Inspect the profiler and +invalid_resident_response events, not just HTTP status or a terminal phase. +Changing prompts or actor/memory configuration can change live behavior, even +for minimal actors. The provider may reject a schema, time out or truncate an +answer; those failures are not permission to invent a resident's consent. + +Two preliminary basic/local-embedding nights reached dawn but had ten and seven +malformed resident outputs respectively; successful transport was not valid +actor behavior. Their evidence is retained. The second private browser harness +also timed out on a large developer screenshot after reaching dawn; later +harnesses write machine-readable evidence before optional screenshots. +A subsequent basic/llama3.2:3b/all-minilm schema-routed night passed strict +format and Chromium checks: 12 automated human inputs, 24 Sequential steps, +48 successful local generation calls, 196 embedding requests, zero malformed +resident responses and no browser errors. It took about 305 seconds of +automated wall time. Six of nine facility-watches were supplied; no repair was +forced. This single run does not establish reliability across models or seeds. +Automated runs do not establish physical Android usability, human play duration, +deterministic replay or empirical social validity. + + +### Inspecting a large developer snapshot + +The attached editor receives authoritative state through the existing service. +Its Snapshot preview is closed initially and is explicitly abbreviated. Select +a state section (for example, target or join_requests) to inspect it, and use +Refresh preview when a newer received revision is indicated. Incoming updates +do not rewrite the preview being read or reset an unsent operation draft. A +stale edit is still rejected by the existing server validation. + +Download received JSON exports the original last-received event text, including +large integer identifiers; it does not parse and re-serialize them in JavaScript. +The preview marks unsafe integer values and limits nested values, text and lists. +It must not be used as a complete state or checkpoint. The downloaded developer +snapshot can contain private actor information; it is not the sanitized public +account, nor is it a complete resumable engine checkpoint. This change reduces +eager DOM rendering, not server/SSE payload size or +network cost. Full download occurs only when requested. + +### Unavailable resident responses + +A malformed resident response is a technical failure, not the resident's +refusal, uncertainty or speech. The game records a neutral response-unavailable +notice for the intended task audience without echoing the raw output. No new +decision, consent or material effect is inferred, and an existing commitment +is not silently revoked. Valid refusals and other valid decisions retain their +normal behavior. The turn still progresses; no automatic model retry or free +replacement player action is added. + +At dawn, an unavailable reply is represented by null in dawn_responses and is +labelled “Response unavailable” in the player view. It is not added to dialogue +as invented first-person words. Public accounts include only publicly delivered +failure notices; a private exchange's failure does not become public. The +private invalid_resident_response diagnostic is retained for developers. Old +saved records are not rewritten, and schema-constrained models can still fail. + +### Interrupted runs in the player view + +A closed human-input session is not evidence that a run completed. The player +view uses the existing run phase to distinguish completion, unexpected stop and +input closure. After failure, every approved role (including spectators) sees +a neutral stopped-run notice, not a success or indefinite waiting message. +Private provider diagnostics are not included in that notice. + +Recorded scoped journals, map inspection and the existing public-account +export remain available while the service is connected. Unsent local drafts +survive reload. The account export remains labelled interrupted and is not a +saved game. Reloading does not restart the run; no automatic retry, replay or +replacement worker is added. Human action/Begin controls stop accepting input, +and unrelated host-approval messages cannot overwrite the terminal status. + +### Current-state delivery to slow clients + +The attached SSE listener uses the standard operation service's optional +coalesced wakeups. It retains at most one pending notification per client, +instead of materializing and queueing full snapshots that the listener would +discard. The listener still builds the current authorized snapshot at delivery, +including rechecking the browser's role. Direct snapshot subscriptions retain +their existing default behavior. + +This is a current-state feed, not a promise to deliver every intermediate +revision separately. The domain event ledger and latest revision retain all +published updates. JSON envelopes, reconnect snapshots, heartbeat comments, +player privacy and read-only exports are unchanged. Full delivered snapshots +can still be large; this change does not compress their contents or establish +any model-latency, bandwidth or physical-device performance result. diff --git a/concordia/examples/bellwether/MULTIPLAYER.md b/concordia/examples/bellwether/MULTIPLAYER.md new file mode 100644 index 000000000..f321c7cfd --- /dev/null +++ b/concordia/examples/bellwether/MULTIPLAYER.md @@ -0,0 +1,91 @@ +# A shared Bellwether night + +This optional mode replaces **only Nell’s acting policy** with HumanActComponent. +A second person controls Nell while the coordinator makes the twelve watch +choices.

Each descriptor documents the +input fields. Session/project/run/branch references are explicit and +process-lifetime, not checkpoint identifiers. Retry keys are retained for that +lifetime; if the ledger reaches capacity, new mutations are rejected rather than +evicting replay protection. + +## Execution and privacy boundaries + +A pause flag does not prove quiescence. This first increment deliberately rejects +edits while the execution thread is alive, **including when awaiting a human**. +It permits the designated edit before starting, and after the worker has fully +returned with the controller paused. One run cannot be replaced or restarted. +Continuing, restoring, cancelling model calls, or editing in-flight work is not +supported. No engine or StepController stepping semantics are changed. + +The editor's graph/inspector remains a read-only view of initial prefab data; +its attached operation panel explicitly shows last-safe runtime state and traces. +Legacy run/edit endpoints are disabled for capability-bound listeners so no GUI +or CLI caller can bypass revisions or the quiescence guard. Normal +`SimulationServer` users without an operation service keep the existing routes. + +The player listener delivers only public scenario configuration and the human +coordinator's own `HumanSession` snapshot. It never sends developer checkpoints, +resident private observations, or the edited private account. Unknown/legacy +player routes are denied; the player cannot select a developer audience in JSON. +SSE uses that same filtered view and replays a current snapshot on reconnect. +The service chooses audiences **at listener construction**, not from user input. +These loopback listeners are not authentication against another process on the +same machine; the developer port is for a trusted author. Do not publicly expose +it. The example creates no tailnet route, lobby, credential, or access-control +configuration. Player and developer browsers must use their designated ports. + +## Tests and scope limits + +```sh +python -m pip install pytest playwright +python -m playwright install chromium +python -m pytest -n 0 concordia/examples/bellwether/service_test.py concordia/examples/bellwether/browser_test.py +``` + +Tests use real standard components and HTTP/CLI/Chromium, but prohibit +`Simulation.play` in the service/browser suite.

A max-step limit may stop before dawn; inspect +`case.world.finished` rather than calling a partial trace a complete night. + +The recipe helper only prepares a standard Config and fresh scenario component. +It does **not** run an engine, start a server, upload data, import user-supplied +Python, or serialize live human readers. Call it anew for every run; do not +reuse a built Config's attached components. These are headless/terminal recipe +examples, not a new browser project editor.

Standard minimal/basic builds retain their +normal components and acting order. Basic's perceptions make additional model +calls; enabling a human final action does not automatically disable its +LLM-backed context processing. + +## Included analogous recipes + +All cases deliberately retain the five fixed Bellwether role IDs and three +facility IDs so existing parsing, scheduling and accounting remain meaningful. +They are variations of one resource-sharing skeleton, not arbitrary-world +generators. + +| Recipe | Explicit change | Expected software effect | Not implied | +|---|---|---|---| +| `bellwether` | Original initial context and ledger | Baseline8 fuel,1 part,9 facility-watches | Fixture cooperation predicts people | +| `mutual-aid` | Ferry evacuation framing, Sam's goal/private report,2 fuel already consumed before play | Generator4 + reserve2 + Used2; only6 usable fuel, so even repair leaves unmet demand | Missing fuel vanished; the rumor is objective fact | +| `resource-governance` | Proposed transparent reserve charter and Nell's goal | Same text appears in institutional view and member context; dialogue may differ with a live model | New voting, sanction or veto enforcement exists | +| `institutional-dispute` | Different private recollections; High Tide note goes only to Mara/Nell | Coordinator/Ivo/Sam/spectator do not receive the direct note | Recipients cannot choose later to disclose it; either recollection is true | + +`case.manifest` records fixed IDs, engine, human roles, accounting baseline and +evidence class without exporting private accounts. For mutual aid, +`epilogue.fuel_used` is the **cumulative Used ledger**, including2 pre-play units. +Subtract `manifest['fuel_consumed_before_play']` to measure in-run consumption. +Do not compare it to the baseline as if both started at zero. + +## Tested modifications and extension boundaries + +### Private information and setting + +The recipe changes both the actor's `PreviousStormAccount` Constant and the +recipient-scoped initial observation. It does not leave a conflicting default +account in the queue. `StormNight.seed(opening=..., accounts=...)` validates all +resident names/text before emitting anything. Use `world.emit(..., audience=[...])` +for delivered facts/claims; a character goal or hidden account is not public. +Public player projections must not include developer checkpoints or raw logs. + +For browser use, `run --dispute-file file.json` accepts exactly: + +```json +{"text":"A disputed claim, not established history.","recipients":["Mara","Nell"]} +``` + +This changes a delivered account, not past objective events. Never patch module +globals to customize simultaneous runs. + +### Institutions: rule, belief, enforcement, compliance + +`StormNight(..., institutions=[...])` accepts unique named institutions with +known members and text `rule`/`enforcement` fields. The same per-world list +feeds member affiliation components and the player view; defaults are unchanged. +For example: + +```python +institutions = [{ + 'name': 'Mutual aid council', + 'members': ['Nell', 'Ivo', 'Sam'], + 'rule': 'Propose public notice before reserve release.', + 'enforcement': 'Proposal only; existing owner consent remains the gate.', +}] +``` + +Text is an actor-facing institutional description, **not executable authority**. +Changing actual enforcement requires a reviewed change to the relevant +`StormNight._human` / `_resident` transitions, explicit new records and tests +for refusal, revocation, unauthorized attempts and boundary timing. Do not +replace the consent gate with a prompt asking a narrator to infer compliance. +Membership, agreement, intended action and performed labor are separate facts. + +### Scarcity, repair and outcomes + +The supported teaching scarcity variation uses standard inventory transfers to +record prior consumption. Total conservation stays8 fuel and1 part. Changing +total resource supply, transfer amounts or facility demand beyond that requires +coordinated edits to `new_inventory`, invariants, reserve contract, opening, +repair/boundary rules, UI and outcome definitions. A hidden Constant edit alone +does not change inventory and must not be reported as a scarcity intervention. + +Likewise, changing `CONSEQUENCES` wording changes presentation, not the number +of supplied facility-watches. Add a new outcome only with an explicit data +source, denominator and interpretation. Tests should check changed transitions, +not assert a desired political narrative or winner. + +### Actor policy, human roles and roster + +```python +case = researcher.prepare_case( + 'resource-governance', + coordinator_reader, + actor_logic='basic', + human_readers={'Nell': nell_reader}, +) +``` + +Both readers use the existing transport-neutral HumanInput protocol; role +authorization remains the transport's responsibility. Other residents retain +ConcatAct. Choose `minimal` or `basic` without copying their build functions. +Individual trusted InstanceConfig `decision_logic`, `goal` and `account` +parameters can be edited **before** building Simulation. + +For live actors supply a local model through standard +`Simulation(..., override_agent_model=...)`, retaining the explicit GM policy. +Reuse the call-limit, profiling and bounded Ollama configuration in `run.py`; +do not silently fall back to fixture behavior on model errors. Zero embeddings +in the teaching snippet are not a realistic basic-agent retrieval setup. +For real local vectors use the optional callable adapter described in +[GAME.md](GAME.md#optional-local-memory-embeddings). The same embedder can be +passed directly to standard `generic.Simulation` in this terminal example. +Record the selected embedding model alongside the actor model and assumptions; +one small successful retrieval probe is not evidence of general memory quality. + +Humanizing a known resident via `human_readers` is supported. Arbitrary roster +size is **not** a one-line Bellwether option: add role/prefab instances, parser +targets, request ownership, observation recipients, agenda/dawn rules, role UI +and invariants together. The current browser authorizes only Coordinator/Nell +plus a spectator. Standard Config supports other entities, but this scenario's +fixed consent and resource contracts still name Nell/Ivo. Unknown role mappings +are rejected rather than silently ignored. + +### GM policy and other engines + +The existing GM composes standard SwitchAct with explicit rules. Alternative +GM context/action components can be composed through a trusted Config, but must +implement the selected engine's action-spec and next-actor contracts and +preserve declared observation/privacy boundaries. A new narrator is not +permission to grant consent or invent resources. + +The main game stays Sequential. Merely passing another engine is not a verified +variant: different scheduling/action-spec contracts can invalidate an agenda +designed for one actor at a time. A subsequent standard-engine example should +document and test those differences, not implement a replacement loop. + +## Validation, traces and research limits + +`researcher_test.py` constructs every recipe using standard Simulation, +checks minimal/basic human-vs-AI policies, fresh component ownership, exact +private account seeding, recipient-bound dispute delivery, valid/invalid +institution state and conservation. Direct rule tests are unit checks, not +live-model runs. The bounded integration smoke uses a scripted fixture and +standard Sequential; a completed night still says nothing about human validity. + +Keep the original configuration, explicit assumptions, backend/model/options, +software revision, human inputs, intervention timestamps and full raw trace +when doing private analysis. Logs include private prompts/memories: do not give +raw JSON/HTML to a player or public spectator. Export only intentionally +sanitized recipient projections. Seeds with hosted models are not a guarantee +of deterministic replay. Component state serialization is not a complete +checkpoint/engine continuation contract; create new independent cases until +that contract is implemented and verified. + +Research needs plural decision logic and a defensible design, not just fluent +dialogue: state hypotheses in advance, justify observations/outcomes, record +counterexamples, separate rules from beliefs/enforcement/compliance, and seek +external evidence. No scripted scientific conclusion, policy recommendation, +trust score, human usability result or social generalization follows from this +fixture, these tests, or a single local-model night. + +## Standard-engine companion + +[ENGINES.md](ENGINES.md) provides a runnable simultaneous resource council, +actual scheduling/API differences, and explicit asynchronous limitations. +The main Bellwether night remains Sequential. + +## Select the same initial case in the browser + +From this source checkout, choose a named trusted recipe explicitly: + +```sh +python -m concordia.examples.bellwether.run --mode fixture \ + --recipe mutual-aid --editor-port 8784 --player-port 8785 \ + --output runs/mutual-aid-fixture +``` + +Open the printed **Player** URL. The page labels the teaching case and its +initial assumptions. **Begin the night** is explicit; opening/reloading the +page never runs or resets a simulation. The server uses the exact +`prepare_case` Config/world described above, not a copied recipe interpreter. +For the host-approved two-human path add `--multiplayer`; Coordinator and Nell +retain their own input and observation scope. The host must approve both players. +Other residents keep the selected standard minimal/basic policy. + +Choose from `bellwether` (unchanged default), `mutual-aid`, +`resource-governance`, or `institutional-dispute`. To use available local +residents, replace `--mode fixture` with `--mode live --model llama3.2:3b`; +fixture results do not establish live behavior. This change verifies initial +recipe selection, not another live night or human usability result. + +`--recipe` is an initial-launch choice, **not** an editor operation for changing +an active game. Use a different output directory and unused ports for each +independent night. The one-turn `--mode slice` excludes non-default recipes. +`--dispute-file` is supported only with `--recipe bellwether`; combining it +with another case is rejected before reading the file or constructing a model +or service. No file may supply importable Python or a new recipe name. + +The mutual-aid case starts with Generator4 + reserve2 + Used2. **Used is a +cumulative ledger**: two units were consumed before play. The browser labels +this condition and the public account includes the declared opening/initial +condition events. The dawn `fuel_used` field remains cumulative for compatibility; +subtract the manifest's `fuel_consumed_before_play` when measuring in-night +consumption. This is not a post-hoc deletion of resources or an experimental +comparison with a shared baseline. + +The saved `outcome.json` player projection and developer initial view include +the public recipe manifest (not private account text). Existing JSON/HTML raw +traces still contain private context and must remain host-only. The public +account continues to omit recipient-only dispute notes and private accounts. + +Regression checks compare exact initial actor states, Config instances and +worlds against independent headless builds for every recipe and both standard +policies. Chromium verifies 360px openings, initial stocks/charters, reload and +host-approved recipient-only dispute delivery using a component fixture. These +checks do not invoke Simulation.play or a model; existing full-game execution +wiring is unchanged. Checkpoint, arbitrary project authoring, experimental and +physical-device acceptance remain separate. + +## Image input versus presentation + +The public service figure is a presentation artifact. [Visual notes](VISUAL-NOTES.md) +instead send bounded normalized pixels to an explicitly selected local vision +model and return a separate human-review draft. There is no automatic path into +an actor observation or scientific evidence. The standard actor interface stays +text-only; do not attach a player's private image to a model instance shared by +other roles. + + +### Setup context in a public account + +Saved public JSON, readable HTML and the public SVG now carry the trusted +recipe's declared setup: recipe name, standard actor prefab/engine, human role +names and initial fuel assumptions. The mutual-aid recipe declares two units +used before play and six initially available; cumulative Used must not be +confused with consumption during play. + +This optional public projection is **not a complete run configuration**. +Private component edits, initial memories, prompts, model settings, browser +identities and session references are excluded. A recipe label neither captures +all interventions nor guarantees deterministic replay or empirical validity. +World-only/older records without setup provenance remain explicitly unknown; +the exporter never infers setup from later stock or narrative. diff --git a/concordia/examples/bellwether/VISUAL-NOTES.md b/concordia/examples/bellwether/VISUAL-NOTES.md new file mode 100644 index 000000000..510406198 --- /dev/null +++ b/concordia/examples/bellwether/VISUAL-NOTES.md @@ -0,0 +1,100 @@ +# Optional local visual notes + +This is **model image input**, separate from the public SVG presentation and +browser speech controls.
