Subject: [PATCH 01/11] Raise repository snapshot limits and build snapshots
 through temp files

Repository workflows (site.health_improve, product.code_map) failed on the
workspace limits, and content delivery stopped on files over the 2 MB
per-file limit. Raise the runaway guards: 100,000 files (GitHub's recursive
tree truncates there anyway), 250 MB snapshot, 1 GB tarball, 10 MB per file,
500 blob fallbacks; selected-file reads 100 MB / 20,000 files.

The byte bounds are set by the switchboard VM (an e2-small with about 1 GB
of free RAM and under 5 GB of free disk), which every run in flight shares.
The verified files now wait in a temporary file instead of a dict in memory,
so the switchboard only holds the finished compressed archive. The isolated
sandbox's per-root entry bound rises to 400,000 so a 100,000-file snapshot
plus its .git objects fits (needs a template rebuild to take effect).

Subject: [PATCH 02/11] Let project memory read 700 KB of sources and keep the
 newest that fit

project.memory d711b841 failed with "memory sources exceed 200000 bytes".
The sources go whole into one gardener call and the index into later
sessions, so both stay within ~200k tokens: 700,000 bytes. Older sources
that no longer fit are left out instead of failing the run. The bounded
project-file read rises to match the index.

Subject: [PATCH 03/11] Start new hosted projects at $25 a run, $100 a month,
 $50 per scheduled run

75 scheduled runs were refused for no sufficient standing limit and four
manual starts for the $10 monthly limit. Only projects without a policy get
the new defaults; saved policies, credits and the welcome grant are unchanged.

Subject: [PATCH 04/11] Give content delivery 15 minutes to read and rebuild a
 repository snapshot

A refresh delivery downloads up to a 1 GB tarball and rebuilds a snapshot of
up to 250 MB on the shared-core switchboard before it commits; 5 minutes
could run out for a large repository. Activity timeouts are not part of

Subject: [PATCH 05/11] Model calls: 32,000-token default cap, 600-second
 default wait, stop signals on receipts

Production caps caused failures without saving money: billing charges the
tokens a call actually used, so a cap only decides when a long answer fails.

- ModelRequest.max_output_tokens defaults to 32,000 (was 4,096). Every
  native caller sets its own cap, so no current request or fingerprint
  changes.
- Provider clients wait 600 seconds by default (was 90), and so does
  TIN_LITE_LUNA_TIMEOUT, which also feeds the Responses client. Activities
  that wrap a default wait now outlast it: project memory, scan report and
  weekly brief 12 minutes, visibility audit 35, answer page 25, character
  design 45, organic panel preparation 85, observation 25, brand checks 35,
  and keyword collection 60. Timeout values are not part of replayed
  commands.
- An empty response at its cap, or one the provider says stopped there
  (Anthropic max_tokens, Gemini MAX_TOKENS, OpenRouter length), is
  output_truncated rather than invalid_result when its structured answer is
  empty or unparseable. Plain text at the cap is still returned.
- native_model_usage_v1 and model external_usage_v1 receipts add
  max_output_tokens, stop_reason and output_truncated. The fields are
  additive; pricing reads none of them.

Subject: [PATCH 06/11] Keyword plan v8: screening caps of 32,000 and 64,000
 tokens

v7 is deployed, so it stays as it is. In runs a59cded8 and de1a4d3e the
screening call stopped at exactly 5,000 output tokens after 3.5-4.2k tokens
of reasoning, and v7's 8,000/16,000 caps are sized like answer lengths
rather than runaway guards. New definitions pin keyword-plan-v8 (catalog
organic.keyword_plan 0.8.0): v7 with only the screening caps and their
reservations changed. Batches stay at 50; reasoning effort stays the
model's choice.

- First attempts get 32,000 output tokens and the one retry 64,000, half
  of GPT-6 Luna's 128,000.
- An 80,000-byte request is 84,096 input tokens to the recorder (standard
  band), so the largest first attempt costs $0.0265 and reserves $0.03,
  and the largest retry $0.0425 and reserves $0.045. Six batches and six
  retries reserve $0.45, and a full run at most $2.00: seeds $0.10,
  review $0.15, screening $0.45, 22 lookups $1.10, 40 samples $0.20. The
  $2 floor covers it exactly, so the floor, the catalog default and the
  organic system's keyword limit are unchanged.
- Seeds and review keep their caps; raising either would pass the floor.
- Screening waits up to 600 seconds per call (was 240) for every policy;
  waiting never changes a request.
- v2-v7 stay registered and send exactly what they did.

+- Screening now waits up to 600 seconds per call (it was 240), for every policy: waiting
+  longer never changes a request. `keyword_collect` may run for 60 minutes (it was 25), enough

+- Runs pinned to v2-v7 send exactly the requests they did.

+"""Keyword screening with output caps sized as runaway guards, not as expected lengths.
+
+v7 (deployed, so immutable) screens in batches of 50 with an 8,000-token cap and one retry at
+16,000. GPT-6 Luna counts reasoning against that cap, and in production the screening calls of
+runs a59cded8 and de1a4d3e stopped at exactly 5,000 output tokens after 3.5-4.2k tokens of
+reasoning. A cap only stops a run; billing charges the tokens a call actually used, so a tight
+cap saves nothing. v8 keeps everything else in v7 (batches, research, seeds, review,
+instructions, schemas and the saved-research retry) and changes only the screening caps and
+their reservations:
+
+- First attempts get 32,000 output tokens and the one retry 64,000, at least six times the
+  largest screening output observed. GPT-6 Luna allows 128,000 output tokens per response
+  (https://developers.openai.com/api/docs/models/gpt-6-luna); both caps stay below it.
+- Each screening request stays bounded to 80,000 bytes of JSON; Tin's model-usage recorder
+  counts those bytes plus 4,096 as input tokens (84,096, standard band). At the pinned rates
+  (`service_pricing.CARD`: $0.125 per million for input or cache writes, $0.50 per million
+  for output) the largest first attempt costs 84,096 x $0.125/M + 32,000 x $0.50/M = $0.0265
+  and the largest retry 84,096 x $0.125/M + 64,000 x $0.50/M = $0.0425. First attempts reserve
+  $0.03 and retries $0.045.
+- A run reserves at most six batches and six retries ($0.45), so its worst case is seeds
+  $0.10, review $0.15, screening $0.45, 22 lookups $1.10 and 40 samples $0.20: $2.00, exactly
+  v6's $2 floor, so a ceiling at the floor still never refuses a call.
+
+Seeds (2,000 tokens) and review (24,000 tokens) keep v7's caps: their requests may reach the
+long-context band, and raising either to 32,000 would lift the worst case past the $2 floor
+that the catalog, the organic system's default keyword limit and the start gate all share.

Subject: [PATCH 07/11] Raise native model step caps to 32,000 through each
 step's own versioning

A cap only decides when a long answer fails; billing charges the tokens a
step used. Runs pinned before keep their caps.

- content.plan 0.9.0 pins content-editorial-v8: v7 with 32,000 output
  tokens (was 16,000). At its bounds a plan costs at most $0.088, still
  under the $0.10 its $1 share in the organic system is sized from.
  Definitions pinned to v7 resolve to v7.
- style.capture 1.3.0 (policy 2, was 6,000), social.x_style 1.2.0 (policy 3,
  was 6,000) and social.x_revise 1.2.0 (x-feedback-v2, was 8,000). Style
  capture and X revisions now accept every policy version they shipped and
  send the pinned cap; contexts saved before keep 6,000. x_style's policy 1
  no longer follows style capture's current cap.
- growth.onboarding_plan steps all use 32,000 (were 6,000-16,000); the
  plan's contract digest changes, as with any change to its module.
- creative.character (was 24,000; four Sol calls at every bound cost about
  $1.73 of its $2 ceiling) and the site-health fix (was 16,000), which pin
  no cap.
- Skipped: the organic audit (its $2 ceiling is computed from 6,000-token
  calls), paid ads (Sol reservations sized from their caps), keyword seeds
  and review (would pass the $2 floor) and code workflows.

Subject: [PATCH 08/11] Raise code workflow limits to runaway guards; bound
 model input per run

Production runs kept hitting conservative code-workflow limits (#273's model
wait, the 64 KB read cap worked around in #89, #239, #261, #270). Limits are
now set well above real use, while model context stays bounded per run.

- timeout_seconds max 60 -> 900 (still the package window and each model
  call's wait; the provider now waits as long instead of its 90 s default);
  execute_code_workflow start_to_close 4 -> 20 min, heartbeats unchanged.
- Model routes: 8 -> 32 calls per run, 4 -> 16 per route, max_input_bytes
  32,000 -> 256,000, max_output_tokens 4,096 -> 32,000; response 64,000 ->
  1,000,000 bytes.
- New run-level budget: at most 700,000 model input bytes (~200k tokens)
  across a run's calls, counted from each call's receipt so retries cannot
  resend it; a call past it fails with model_input_budget.
- Run maximum: input priced at 3 bytes/token within the shared 700,000-byte
  budget, filled at the most expensive route first, plus each call's
  4,096-token envelope and full output. Per-call reservations use the same
  rate, so every admissible call sequence fits the pinned maximum. Admitted
  runs keep the terms pinned in their budget.
- File reads and output artifact 64,000 -> 1,000,000 bytes; file calls
  64 -> 256, bridge calls 32 -> 128; bridge message 128 KB -> 4 MB and
  result envelope sized for a 1 MB artifact.
- Service bindings: max_calls 8 -> 32 (per binding and total), responses
  64,000 -> 1,000,000 bytes; gateway wait 25 -> 60 s, Google 22 -> 55 s,
  custom API 20 -> 55 s.
- Authoring guide, creator contract and docs state the new bounds.

Subject: [PATCH 09/11] Raise Codex limits to runaway guards: contract v5, $10
 sessions, longer sandboxes

New Codex admissions pin tin-codex-api-v5: v4's 128,000-token output and
8 MiB requests with a 256,000-token context that compacts from 200,000.
Session-funded procedures keep no request/token stop; included, child,
Studio, diagram, design and task work pin the same shape with 256-request
and 8M-token runaway stops and a $1.93 per-request reservation. Funding is
unchanged: Start here work stays included and Tin-funded.

The default root Codex ceiling is $10 (children inside a parent budget keep
$5). Runs and still-valid quotes from before v5 keep v1-v4 and $5.

Procedure sandboxes may declare up to 7,200 s; design/task sandboxes default
to 1,800 s; compute activities allow 3 h (6 h with retries); proxy grants
cover the longest sandbox. Relay rejections (413 context bound, 422
contract, request/token limits, upstream errors) are stored on the attempt
receipt as relay_rejection and named in the run's failure message.

+
+New admissions pin **`tin-codex-api-v5`**. It keeps v4's 128,000 output tokens per response
+and 8 MiB requests, but the controller declares a 256,000-token context window and compacts
+from 200,000 tokens. A request therefore stays near 200,000 tokens of context in ordinary
+use, below the 272,000-token long-context price band; one large tool result can still exceed
+it until the next compaction. Session-funded procedures (`SESSION_CONTRACT`) have no request
+or lifetime-token stop, as in v4. Codex work that is not session-funded pins the same shape
+with runaway stops (`PROCEDURE_CONTRACT_V5`): 256 requests and 8,000,000 observed tokens,
+four times the most seen on v3 (64 requests, 2.04M tokens). That covers included Start here
+setup children, other parent children, Studio, diagrams/video (whose images fit in any 8 MiB
+v5 request, so the separate v3 diagram text bound is not carried over), `content.design_md`
+and `project.task`. Their funding is unchanged: included work stays Tin-funded with no
+customer reservation, and the others reserve per request. A v5 request reserves $1.93: its
+256,000-token context as cache writes, 128,000 output tokens and one search call.
+
+The default ceiling of a root Codex run is $10 for new admissions ($5 before; a child inside
+a parent budget keeps $5, since parent pools were composed from $5 children); explicit smaller
+ceilings such as `content-refresh.v1`'s $2.50 are unchanged. Runs and quotes admitted before
+v5 keep v1-v4 and $5: a still-valid quote issued before v5 is admitted with exactly the terms
+it showed. The controller image reads v5's window from its own protocol table, so deploying v5
+needs rebuilt isolated, browser API and Studio API templates that answer
+`codex_api_config.py --check-v5`; the runtime refuses to start a v5 run on an older image.

+## Codex procedure limits as runaway guards — October 2, 2026
+
+Over the 30 days before this change, two Codex sessions (a code map and an email shortlist)
+stopped at exactly $5; the code map's p90 was $4.30 and every other Codex workflow's p90 was at
+most $2.30. Older contracts stopped runs at 64 requests, 2M observed tokens or a 128,000-token
+context. New admissions now pin [contract v5](codex-api-pilot.md#contract-v5-a-bounded-context-and-10-sessions-october-2-2026):
+
+| Limit | Before | Now |
+| --- | --- | --- |
+| Default ceiling of a root Codex run (`content.generate`, code map, email shortlist and others without their own) | $5 | $10 |
+| Ceiling of a Codex child inside a parent budget | $5 | $5, unchanged |
+| `content-refresh.v1` ceiling | $2.50 | $2.50, unchanged |
+| Session context | 1,050,000 tokens, compaction at 922,000 | 256,000 tokens, compaction at 200,000 |
+| Per-request funded and included Codex work | v1/v3: 8-64 requests, 0.1-2M tokens, 4,096-8,192 output, 128,000 context | 256 requests, 8M tokens, 128,000 output, 256,000 context |
+| Per-request reservation | $0.41 (v3) | $1.93 |
+| Maximum declared procedure sandbox time | 3,600 s | 7,200 s |
+| Design and task sandbox time (`TIN_LITE_SANDBOX_TIMEOUT` default) | 900 s | 1,800 s |
+
+Funding is unchanged. Ordinary root procedures are sessions; Studio, diagrams/video, design,
+tasks and parent children reserve per request; both Start here workflows and their approved
+setup children stay included, Tin-funded and bounded by v5's request and token stops, with no
+customer reservation. Parent pools (for example the traffic system's) are unchanged and were
+composed from $5 children, so children keep $5. A procedure that does not declare a timeout
+still gets 900 s: that default is written into built-in definitions, and raising it would
+change pinned catalog contracts without a version. Runs and quotes admitted before
+the change keep their pinned contract and $5.
+
+A $10 session maximum is also its configured estimate. Admission refuses a run only when the
+estimate exceeds the per-run limit, so a $10 run fits a $10 per-run limit. It does count $10
+against the monthly limit while it runs: under the September 29 hosted defaults ($10 a month)
+one weekly `content.generate` can be admitted each month, not five, until those limits rise.

Subject: [PATCH 11/11] Make the code run's model input bound a logged soft
 gate

A run whose model calls pass 700,000 input bytes still sends the call; Tin logs one
warning for the run with its ID, workflow, step and byte counts. The run maximum
reserves every declared call at its full max_input_bytes (three bytes per token),
since the bound no longer refuses anything.
